CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

1.0Executive Summary

 

1.1Introduction

 

Chilwa Minerals Ltd (CML) requested Belenos Holdings (Pty) Ltd (Belenos) to prepare a technical report for the Chilwa Critical Minerals Project in compliance with Item 1300 of Regulation S-K promulgated by the United States Securities and Exchange Commission (SEC). The Project is in southern Malawi along the shores of Lake Chilwa.

 

1.2Property Description

 

Lake Chilwa is in Southern Malawi on the eastern border with Mozambique. The Project is located along the shores of Lake Chilwa, covers an area of 881.0136 km2 and historic exploration work on the northern and western shores indicated the presence of well mineralized fluvial and aeolian deposits with potential for economic exploitation of ilmenite and zircon.

 

1.3Accessibility, Climate, Local Resources, Infrastructure and Physiography

 

Malawi is a landlocked country in Southeastern Africa. It is bordered by Zambia to the west, Tanzania to the north and northeast, and Mozambique to the east, south, and southwest The Nacala (harbour town on the Mozambique coast) Corridor railway line runs along the northern shore of Lake Chilwa. Access to the northern and western shore of Lake Chilwa is relatively easy in the dry season but can be tricky during the wet months. The area is densely populated and villages practicing subsistence farming widespread in the area.

 

Malawi’s climate is subtropical, characterized by two seasons: summer and winter. The climate is significantly modified by the varying country’s topography. Summer is wet but hot and starts from October to April.

 

Malawi is among the world’s least developed countries. Around 85% of the population lives in rural areas. The economy is based on agriculture, and more than one-third of GDP and 90% of export revenues come from this.

 

Malawi has 31 airports, seven with paved runways (two international airports) and 24 with unpaved runways. The country has 797 kilometres (495 mi) of railways, all narrow-gauge, and, as of 2003, 24,866 kilometres (15,451 mi) of roadways.

 

Lake Chilwa is in Southern Malawi, on the eastern border with Mozambique. The town of Zomba is located 20 km to the west of the EL, and the commercial capital of Blantyre, is located 80 km to the southwest.

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

1.4History

 

Historic work includes academic studies, prospecting by Brinkmann (Brinkmann 1991, 1992, and 1993), by companies (Millennium Mining Limited Investments, Tate Minerals, and Mota Engil Investments (Malawi) Limited) which included auger drilling, aircore drilling, pitting and bulk sample testing.

 

1.5Geological Setting, Mineralization, and Deposit

 

Malawi geology is dominated by the East African Rift with Lake Chilwa the most southern major lake associated with the rift valley.

 

The regional geology and structural evolution of the Lake Chilwa region in southern Malawi have played a pivotal role in the formation of the lake and in the deposition and preservation of heavy mineral sands (HMS) within the Exploration Licence area. The basement geology is dominated by Pre-Cambrian Age Basement Complex rocks, including paragneisses and orthogneisses, which are widely exposed across the region. These rocks mainly comprise charnockitic gneiss, hornblende-biotite gneiss, and biotite gneiss, with granulite and quartzite occurring particularly to the north of the lake. Many of these basement units contain ilmenite and zircon as accessory minerals. Some of the biotite gneisses are described as garnetiferous, suggesting localized enrichment of heavy minerals. In addition, Pre-Karoo igneous rocks such as the Domasi biotite-granite and associated microgranites, which crop out along the Domasi River, also host abundant titanomagnetite and ilmenite. These rocks contribute significantly to the regional heavy mineral assemblage and the source potential for HMS deposits. A substantial component of the local geology is made up of Jurassic and Cretaceous age alkaline intrusives of the Chilwa Alkaline Province. These include major geological features such as the Zomba Massive (Malosa Mountain) to the west, the Mulanje Massive to the south, and the Mongolowe/Chaone/Chikala Hills to the northwest. Dominant lithologies include nepheline syenite, quartz syenite, and nepheline, with additional intrusives such as the Mpuyupyu Hill syenite and the carbonatite complexes of Chilwa Island and Tundulu. These rocks are consistently reported to contain zircon and ilmenite as major accessory minerals, reinforcing their role as significant contributors to the regional HMS potential.

 

Sediments that were deposited as HMS deposits at Lake Chilwa were eroded and transported from the regional rock masses by various rivers. Studies have shown that because of a predominant SE wind, a north flowing longshore current developed along the western shore of Lake Chilwa during the 631 masl period. The current transported sediments supplied by the rivers northwards along the shore. Fine material was winnowed out through wave action and moved northwards while the larger particles and HMS lagged behind and was concentrated on the beach through the removal of the fine and lighter particles. The SE wind probably also removed fine particles from the beached during lower lake levels and further concentrated the larger and heavier grains. Sediments deposited on the beaches were constantly reworked and matured through a combination of the pulses of sediment supply by the rivers, the longshore current, wave and wind action and fluctuating lake levels.

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

1.6Exploration

 

Claus Brinkmann (Brinkmann, 1991; Brinkman, 1992; Brinkmann, 1993) worked on the Mpyupyu deposit between 1991 and 1993 as part of an initiative by the German Federal Government to aid mineral evelopment in Malawi.

 

Millennium Mining Limited Investments (MML) explored the north shore HMS deposits with an auger drill programme of 31 holes and 104 air core (AC) holes were completed by Wallis Drilling on a 100 m × 100 m grid.

 

Tate Minerals (Tate) applied for the Lake Chilwa EL in 2012. Tate retrieved and digitized all available data and reports and had independent consultants review the results. In 2014, Tate entered a JV with Mota-Engil Investments (Malawi) Limited (MEIML) to explore the HMS deposits identified by previous exploration activities.

 

MEIML undertook several early-stage assessment programmes, including metallurgical and process testwork studies, in 2014 and 2015 to verify the presence and HM content of the HMS deposits identified by earlier exploration work. This included auger drilling on existing and new targets as well preliminary process optimization and metallurgical studies.

 

In 2021, Luso Global Mining B.V. (LGM), a fully owned subsidiary of MEIML, expressed a renewed interest in the Project and requested AMC to update the previous MREs using the re-assayed samples. AMC produced an updated mineralized inventories for Bimbi (including Northeast Bimbi), Mpyupyu, Mposa, and Halala, reporting the inventories at 1.0%, 3.0%, and 5.0% THM cut-offs.

 

In 2022, Chilwa Minerals Ltd (CML) concluded the current agreement with LGM. CML requested AMC to constrain the MREs prepared for LGM in 2021 to demonstrate the requirement of reasonable prospects for eventual economic extraction (RPEEE). AMC reported the MREs for the Bimbi (including Northeast Bimbi), Mpyupyu, Mposa, and Halala, at 1.0%, 1.5%, and 3.0% THM cut-offs.

 

CML’s drilling program at the Mposa Main (Mposa) target area commenced on 9 October 2023. The drilling program was designed to test the extent of potential mineralisation at depth as well as its lateral continuity by twinning selected existing holes as well as drilling further holes in the areas adjacent to Mposa. (Chilwa Minerals, 2024). Drilling was spaced 25m across-strike and 100m along strike for most of the targets in the Chilwa project area. Except for Mposa and Mpyupyu Dune, the sonic drilling was on a nominal 50m across strike and 50m along strike grid.

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

1.7Sample Preparation, Analyses, and Security

 

The estimation relies on data from two distinct exploration phases, being the recent work undertaken by Chilwa Minerals, utilising sonic rigs to extract core for Heavy Liquid Separation (‘HLS’) assay (sonic), and the 2014-2016 work undertaken by previous owners MEIML, utilising Aircore rigs as the principal means of capturing samples for HLS assay (Aircore).

 

Sample representivity was ensured through field duplicates generated from the final split of randomly selected samples—one in every 20. Additionally, blanks, site-constructed reference samples, and umpire samples (5% replication) were inserted per batch to monitor data quality. The final 1 kg sample, produced using proper riffle splitting techniques, is considered representative, comprising roughly 10% of the original parent sample.

 

Sample preparation involved initial drying, then crushing to 80% passing 3mm, followed by splitting of a sub-sample on a rotary splitter. The sub-sample (approximately 500g) was sent by air freight to LDE where it was analysed for slimes %, Oversize % and THM %. The Qualified person is of the opinion that the sampling techniques were to industry accepted standards.

 

The samples were sent for Heavy Liquid Separation assay at ALS Laboratory in Perth, Austaralia and, from 2025, to LightDeepEarth Laboratory (LDE), in Pretoria, South Africa (Chilwa Minerals, 2025a).

 

Within the QAQC process, the statistics of the Mposa deposit were compared between the aircore samples and the sonic samples and they correlate very well with only higher variances within the sonic samples.

 

The QAQC analyses on the Mposa sonic drill hole samples, were done on the field duplicates, the standards, the blanks and the laboratory repeats and the summary results were mostly acceptable.

 

It is the Qualified persons’ opinion that the independent QAQC program has demonstrated that acceptable levels of accuracy and precision have been established.

 

1.8Data Verification

 

Verification includes various methods to check and validate the data supplied. It is the Qualified persons’ opinion that the data used for the mineral resource estimates were adequete for the purposes used for the reporting in this technical report summary.

 

1.9Mineral Processing and Metallurgical Testing

 

Several metallurgical studies were completed by SGS, Mintek, AML and LDE on representative samples from the HMS deposits of the Lake Chilwa project. Detailed reports are available for the studies. The studies show that the mineralized sand from the HMS deposits can be processed into high grade ilmenite and zircon products with high recovery rates.

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

1.10Mineral Resource Estimate

 

Sectional interpretation was done on all the Chilwa Northern Deposits (Nkotamo, Halala, Beacon and Namanja West) on the project. On each section line the basal clay contact were modelled. These sectional interpretations were then wireframed to form DTM surfaces. The modelled basal clay contact of Mposa used, was modelled by the project geologist in Leapfrog. The basal clay contacts of Bimbi, Bimbi NE and Mpyupyu used, was modelled by AMC.

 

Univariate statistical analysis was carried out on the variables, THM %, Slimes % and Oversize % of the 1 m composited drill hole data on all the deposits in the June 2025 estimations, using Excel and Surpac.

 

Reflecting an overall change in strike from NNE to NE over the 8km of strike of the Mposa deposits, three mineralised domains were created in the November 2025 update, Main NE, Main SW (together referred to as Mposa Main) and Mposa North, that were formed along the northwestern edge of Lake Chilwa. Univariate statistical analysis was carried out on the variables, THM %, Slimes % and Oversize %, HfO₂ %, TiO₂ %, and ZrO₂ % of the 1m composited drill hole data using Excel and Surpac for each domain.

 

The inverse distance method for grade interpolation was used for the project area, with the estimation parameters derived from calculated variograms. Variograms were modelled for the following variables: THM %, Slime % and Oversize % from the composite data for each deposit area: Mposa NE and SW, Mpyupyu, Bimbi, Bimbi NE and Chilwa North. Variograms were calculated in Surpac with the composite data.

 

Mineralogy has been undertaken on THM concentrates using chemical data obtained using XRF combined with QEMSCAN analysis.

 

Block models with block sizes of 100m X 100m X 1m and minimum sub blocking of 25m X 25m X 0.5m were created within Surpac for all the HMS deposits in the June 2025 estimations. A new block model with block sizes of 50m X 50m X 0.5m without sub blocking was created within Surpac for the Mposa deposits in the November 2025 update).

 

Inverse distance with the power of 3 was used for in situ grade interpolation for the THM %, Slime % and Oversize % with the 1m composites within their respective ore domains in the June 2025 estimations for all the deposits.

 

Inverse distance with the power of 2.5 was used for in situ grade interpolation for the THM %, Slime %, Oversize %, HfO₂ %, TiO₂ %, and ZrO₂ % with the 1m composites within their respective ore domains in the November 2025 estimation update for the Mposa deposits.

 

Block model validations were undertaken by visual checking on the block model sections comparing with drilling data, by comparisons of global average input composite data with the block model estimated grades of all the deposits and with swath plot checks on the block model estimates.

 

The resource classification was primarily based on the drill hole density. The estimation passes were used in the classification process.

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

1.11Conclusion and recommendations

 

Under the assumptions presented in this Report, the Chilwa Mineral Sands Project represents a substantial Mineral Resource that warrants technical evaluation and studies.

 

It is the qualified person’s opinion that additional work is justified on the Project to upgrade the mineral resource confidence categories that are relevant to the technical and economic factors likely to influence the prospect of economic extraction.

 

Belenos recommended the following:

 

Infill drilling in the Inferred and Indicated areas to increase the confidence level to higher categories.

 

XRF and QEMSCAN analysis in areas that that are not well covered to increase the confidence level to higher categories.

 

Use the QEMSCAN data to estimate the garnet values in the block models.

 

Updating the resource models periodic per deposit area as soon as all the new drilling assay and QEMSCAN data are available per deposit area.

 

  Define the optimum modelling THM % together with a maximum Slimes % from the metallurgical testings for the economic mining process and re-model the base clay footwall on all deposits accordingly.

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

3.3Environmental Factors and Assumptions

 

Lake Chilwa is recognized as a Ramsar-designated wetland. The Lake Chilwa EPL however covers grasslands along the lake shore used for grazing and farming, and none of the EL or deposits falls within the actual wetland.

 

The mineralized sand deposits are populated by rural farming communities and small villages as they are elevated above the surrounding low-lying areas.

 

Mining activities at Chilwa will involve dry mining methods using loaders and trucks with the expectation at this point in the project that all tailings will be backfilled into the mined-out areas. The low slimes levels of slime of the deposits should allow for the slimes directly backfilled with the gravity and oversize tailings.

 

An extension of the exploration licenses has been granted by the Commissioner of Mines and Minerals from 18/07/2025 for three years for EL0670/22R1, EL0671/22R1 and five years for EL0835/25.

 

At this time, no issues were identified that would materially impact the ability to eventually extract mineral resources at the project.

 

There is a risk that commodity prices may not be consistent with assumptions made as it is dependend on the world economic growth.

 

4.0Accessibility, Climate, Local Resources, Infrastructure and Physiography

 

4.1Accessibility

 

Malawi is a landlocked country in Southeastern Africa. It is bordered by Zambia to the west, Tanzania to the north and northeast, and Mozambique to the east, south, and southwest The Nacala (harbour town on the Mozambique coast) Corridor railway line runs along the northern shore of Lake Chilwa. Access to the northern and western shore of Lake Chilwa is relatively easy in the dry season but can be tricky during the wet months. The area is densely populated and villages practicing subsistence farming widespread in the area.

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

4.2Climate

 

Malawi’s climate is subtropical, characterized by two seasons: summer and winter. The climate is significantly modified by the varying country’s highlands and lowlands topography. Summer is wet but hot and starts from October to April. During the rainfall season, temperature can reach 37°C with relative humidity ranging between 50 to 80 percent. Annual rainfall ranges between 700 mm to 2,500 mm with the highest amounts being experienced over the highlands while the lowlands experience the lowest amounts. About 95 % of the annual precipitation falls during the wet summer season particularly from November to April with the highest rainfall experienced in January and February (Ngongondo et al. 2011 in: State of Malawi Climate, 2025).

 

4.3Local Resources

 

Malawi is among the world’s least developed countries. Around 85% of the population lives in rural areas. The economy is based on agriculture, and more than one-third of GDP and 90% of export revenues come from this. In the past, the economy has been dependent on substantial economic aid from the World Bank, the International Monetary Fund (IMF), and other countries. The Malawian government faces challenges in developing a market economy, improving environmental protection, dealing with the rapidly growing HIV/AIDS problem, improving the education system, and satisfying its foreign donors to become financially independent

(Wikipedia, 2025).

 

4.4Infrastructure

 

Malawi has 31 airports, seven with paved runways (two international airports) and 24 with unpaved runways. The country has 797 kilometres (495 mi) of railways, all narrow-gauge, 24,866 kilometres (15,451 mi) of roadways in various conditions, 6,956 kilometres (4,322 mi) paved and 8,495 kilometres (5,279 mi) unpaved. Malawi also has 700 kilometres (430 mi) of waterways on Lake Malawi and along the Shire River (Wikipedia, 2025).

 

Malawi’s water resources are plentiful, although some rural areas are inadequately supplied. Treated water for the major cities of Blantyre and Lilongwe is supplied by the Walker’s Ferry Scheme and the Kamuzu Dam, respectively. Most of the rivers are seasonal, but a few large ones, particularly the Shire River along its middle course, have considerable potential for irrigation and electricity generation. Power demands are met by hydroelectric schemes, including those at Nkula Falls, Kapichira, and Tedzani Falls, and by diesel plants. Major consumers of electric power include the industrial areas of the south near Blantyre, where electricity consumption has steadily multiplied, and the industrial area of Lilongwe; the vast sugar estates at Nchalo and Dwangwa also consume much electricity. By contrast, only a fraction of Malawians themselves have electrical access, and almost all domestic energy needs are met by firewood (Britannica, 2026).

 

4.5Physiography

 

Malawi is a landlocked country in southeastern Africa, bordered by Zambia to the northwest, Tanzania to the northeast, and Mozambique to the south, southwest, and general east. It lies between latitudes 9° and 18°S, and longitudes 32° and 36°E. The Great Rift Valley runs through the country from north to south, and to the east of the valley lies Lake Malawi (also called Lake Nyasa), making up over three-quarters of Malawi’s eastern boundary. Lake Malawi is sometimes called the Calendar Lake as it is about 365 miles (587 km) long and 52 miles (84 km) wide. The Shire River flows from the south end of the lake and joins the Zambezi River 400 km (250 mi) farther south in Mozambique. The surface of Lake Malawi is at 457 m (1,500 ft) above sea level, with a maximum depth of 701 m (2,300 ft), which means the lake bottom is over 213 m (700 ft) below sea level at some points (Wikipedia, 2025).

 

15

 

 

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

In the mountainous sections of Malawi surrounding the Rift Valley, plateaus rise generally 914 to 1,219 m (3,000 to 4,000 ft) above sea level, although some rise as high as 2,438 m (8,000 ft) in the north. To the south of Lake Malawi lies the Shire Highlands, gently rolling land at approximately 914 m (3,000 ft) above sea level. In this area, the Zomba and Mulanje mountain peaks rise to respective heights of 2,134 and 3,048 m (7,000 and 10,000 ft) (Wikipedia, 2025).

 

Lake Chilwa is in Southern Malawi, on the eastern border with Mozambique. The town of Zomba is located 20 km to the west of the EL, and the commercial capital of Blantyre, is located 80 km to the south-west (Figure 2).

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

Lake Chilwa measures 40 km from north-to-south and 30 km from east-to-west and is a shallow, saline body of water surrounded by dense swamps and marshes. A narrow belt of arable grassland surrounds the lake, which contains the HMS deposits that are being targeted by CML.

 

The lake is a Ramsar designated Wetland, however the EL is contained in a zone of arable grass along the western and northern shore of Lake Malawi.

 

Animal life indigenous to Malawi includes mammals such as elephants, hippos, antelopes, buffaloes, big cats, monkeys, rhinos, and bats; a great variety of birds, including birds of prey, parrots, and falcons; waterfowl and large waders; and owls and songbirds. Lake Malawi has been described as having one of the richest lake fish faunas in the world, being the home for some 200 mammals, 650 birds, 30+ mollusks, and 5,500+ plant species.

 

5.0History

 

Historic work includes academic studies, prospecting by Brinkmann (Brinkmann 1991, 1992, and 1993), by companies (Millennium Mining Limited Investments, Tate Minerals, and Mota Engil Investments (Malawi) Limited) which included auger drilling, aircore drilling, pitting and bulk sample testing (AMC, 2023).

 

In 2016, AMC prepared a MRE for internal use by then owners Mota Engil Investments (Malawi) Limited (MEIML). During this process, it was found that assaying had not been undertaken incorrectly by the assay laboratory and the resource was classified at an Inferred level of confidence. The affected samples were re-assayed and in May 2021 AMC updated the MRE following the receipt of the re-assayed sample data.

 

6.0Geological Setting and Mineralization

 

6.1Malawi Geology

 

Malawi geology (Figure 3) is dominated by the East African Rift with Lake Chilwa the most southern major lake associated with the rift valley. The geology of Malawi is broadly grouped into four main lithological units: the Basement Complex, the Karoo Super group, Tertiary to Quaternary sedimentary deposits and the Chilwa Alkaline province (AMC, 2023).

6.2Regional Geology

 

The regional geology (Figure 4) and structural evolution of the Lake Chilwa region in southern Malawi have played a pivotal role in the formation of the lake and in the deposition and preservation of heavy mineral sands (HMS) within the Exploration Licence area. The basement geology is dominated by Pre-Cambrian Age Basement Complex rocks, including paragneisses and orthogneisses, which are widely exposed across the region. These rocks mainly comprise charnockitic gneiss, hornblende-biotite gneiss, and biotite gneiss, with granulite and quartzite occurring particularly to the north of the lake. Many of these basement units contain ilmenite and zircon as accessory minerals. Some of the biotite gneisses are described as garnetiferous, suggesting localized enrichment of heavy minerals. In addition, Pre-Karoo igneous rocks such as the Domasi biotite-granite and associated microgranites, which crop out along the Domasi River, also host abundant titanomagnetite and ilmenite. These rocks contribute significantly to the regional heavy mineral assemblage and the source potential for HMS deposits. A substantial component of the local geology is made up of Jurassic and Cretaceous age alkaline intrusives of the Chilwa Alkaline Province. These include major geological features such as the Zomba Massive (Malosa Mountain) to the west, the Mulanje Massive to the south, and the Mongolowe/Chaone/Chikala Hills to the northwest. Dominant lithologies include nepheline syenite, quartz syenite, and nepheline, with additional intrusives such as the Mpuyupyu Hill syenite and the carbonatite complexes of Chilwa Island and Tundulu. These rocks are consistently reported to contain zircon and ilmenite as major accessory minerals, reinforcing their role as significant contributors to the regional HMS potential.

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

Following the emplacement of the Chilwa Alkaline Province rocks, tectonic activity along the Rift Valley Fault led to widespread erosion and peneplanation of the valley floor during the Late Cretaceous to early Tertiary periods. The modern landscape around Lake Chilwa consists of residual and colluvial deposits, along with extensive lacustrine and beach sediments composed of silts, clays, and sands. These sediments are closely tied to the lake’s tectonic and depositional evolution and serve as the primary host for current heavy mineral sand accumulations (AMC, 2023).

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

7.0deposit types

 

All the deposits are sedimentary with sediments and HM that were eroded and transported from the regional rock masses by rivers into the Lake Chilwa. A north flowing longshore current developed from the a predominant SE wind, which transported sediments northwards. The sediments transported on the beaches were constanly reworked and matured through a combination of the longshore current, wave and wind action, as well as fluctuating lake levels (AMC, 2023).

 

There is a difference, both in deposit morphology and HMS heavy mineral assembly between the north (Halala and Nemanja) and the western shore deposits (Mpyupyu, Bimbi, and Mposa). This is attributed to the differences in the depositional environment as well as sediment supply to the different areas (AMC, 2023).

 

Several terraces and raised beach levels can be identified around Lake Chilwa. The early Holocene age 631 masl raised beach and terrace are very well developed along the western shore of Lake Chilwa. The lake craved a new terrace out of the older lacustrine silts and clays during this period as well as becoming separated from Lake Chiuta by the formation of the sand bar to the north of the lake. The 631 masl level represents a steady period in the history of Lake Chilwa and the formation of the mineralized beach sand deposits found at Mposa, Bimbi, Namasalima and Mpyupyu were initiated during this period. The water level of Lake Chilwa dropped further and formed the 623 masl raised beach and terrace, a few meters above the present-day lake level. This terrace level slopes gently down to the current lake level, a total drop of almost 10 m from the stable 631 masl level. It is on this raised beach level that the silty mineralized sand deposits of Bimbi NE and Mpyupyu East are preserved and which probably consist of material supplied and reworked from the 631 masl beach deposits along with sediment supply by the inflowing rivers (AMC, 2016).

 

Sediments that were deposited as HMS deposits at Lake Chilwa were eroded and transported from the regional rock masses by various rivers. Studies have shown that because of a predominant SE wind, a north flowing longshore current developed along the western shore of Lake Chilwa during the 631 masl period. The current transported sediments supplied by the rivers northwards along the shore. Fine material was winnowed out through wave action and moved northwards while the larger particles and HMS lagged behind and was concentrated on the beach through the removal of the fine and lighter particles. The SE wind probably also removed fine particles from the beached during lower lake levels and further concentrated the larger and heavier grains. Sediments deposited on the beaches were constantly reworked and matured through a combination of the pulses of sediment supply by the rivers, the longshore current, wave and wind action and fluctuating lake levels (AMC, 2023).

 

Figure 5 is the simplified stratigraphy with a cross-section through Mpyupyu showing the resultant geology of these processes (AMC, 2023). All the deposits are a combination of these processes and can be summarized as in Table 3.

8.1Historic Exploration

 

Claus Brinkmann (Brinkmann, 1991; Brinkman, 1992; Brinkmann, 1993) worked on the Mpyupyu deposit between 1991 and 1993 as part of an initiative by the German Federal Government to aid mineral evelopment in Malawi. A total of 125 test pits were completed on a 500 m × 500 m grid to depths ranging from 2 m to 4.2 m, depending on the hight of the water table. HM-bearing sand was analysed for THM content and ilmenite. Brinkmann also undertook a radiometric survey of the Mpyupyu area. Eighty-eight (88) pits were used to delineate a grade and tonnage estimate of 125 Mt grading 4.3% THM at a cut-off grade of 2% THM (AMC, 2023).

 

Millennium Mining Limited Investments (MML) explored the north shore HMS deposits with an auger drill programme of 31 holes and 104 air core (AC) holes were completed by Wallis Drilling on a 100 m × 100 m grid. MML claimed to have defined a tonnage and grade estimate of 15.4 Mt grading 2.74% ilmenite and 0.2% zircon. No documentation to support the resource was made available to AMC. MML drilled a further 22 auger holes on the Namanja dune followed by an additional 58 auger holes on a 2 km line spacing and 100 m hole spacing. A compliant MRE was claimed by MML from the drilling programme. No supporting documentation was made available to AMC to support this estimate. MML also declared an Inferred Mineral Resource of 30 Mt comprising of 5.20% ilmenite, 0.14% rutile, 0.16% zircon, and 0.20% leucoxene for Halala. This is based on 10 auger holes to a depth of 10 m. No documentation supporting the resource estimation was made available to AMC. MML provided Ticor/Kumba with three bulk samples for testwork. The assemblages from the three samples average 9.8% THM, comprising 46% ilmenite, 6.4% magnetite, 0.7% rutile, 5.7% zircon, and 4.5% leucoxene. The remaining 37% was assumed to be garnets and amphiboles. There was no supporting documentation made available to AMC to justify these results. These MREs were for internal use only and were not publicly reported. AMC did not review the abovementioned statements or estimation methodology applied, and AMC does not assume any responsibilities for the accuracy of the figures (AMC,2023).

 

Tate Minerals (Tate) applied for the Lake Chilwa EL in 2012. Tate retrieved and digitized all available data and reports and had independent consultants review the results. The consensus opinion was that the quality of the previous exploration work accompanied by a lack of detail in the laboratory work and quality assurance and quality control (QAQC) data precluded its use for a compliant Mineral Resource reporting. In 2014, Tate entered a JV with MEIML to explore the HMS deposits identified by previous exploration activities (AMC,2023).

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

Mota-Engil Investments (Malawi) Limited (MEIML) undertook several early-stage assessment programmes, including metallurgical and process testwork studies, in 2014 and 2015 to verify the presence and HM content of the HMS deposits identified by earlier exploration work. This included auger drilling on existing and new targets as well preliminary process optimization and metallurgical studies. Regional auger programmes indicated the potential for additional large, high-grade deposits on the EL. Following the completion of the studies, it was concluded that additional exploration and testwork should be undertaken. In 2015, an air core drilling (AC) and diamond core drilling (DD) programme was undertaken, with the stated aim being to obtain sufficient geological data to allow for a MRE that could be classified and reported. A total of 9,922 m (1,492 holes) of drilling was completed on the Mpyupyu, Bimbi, Mposa, and Halala deposits. MREs were completed and reported for Bimbi (including Northeast Bimbi), Mpyupyu, Mposa, and Halala. Due to a failure in the primary laboratory (SGS in Johannesburg) a significant proportion of the samples were incorrectly assayed resulting in overstated slimes and slightly understated THM values. This resulted in the MREs being classified at the Inferred level of confidence. The MREs produced were in situ resources that were not constrained by a pit shell. These MREs were for internal use only and were not publicly reported. The compromised samples were re-assayed, however, MEIML had decided to discontinue the exploration programme and the relationship with Tate (AMC,2023).

 

In 2021, Luso Global Mining B.V. (LGM), a fully owned subsidiary of MEIML, expressed a renewed interest in the Project and requested AMC to update the previous MREs using the re-assayed samples. AMC produced an updated mineralized inventories for Bimbi (including Northeast Bimbi), Mpyupyu, Mposa, and Halala, reporting the inventories at 1.0%, 3.0%, and 5.0% THM cut-offs (AMC,2023).

 

In 2022, Chilwa Minerals Ltd (CML) concluded the current agreement with LGM. CML requested AMC to constrain the MREs prepared for LGM in 2021 to demonstrate the requirement of reasonable prospects for eventual economic extraction (RPEEE). AMC reported the MREs for the Bimbi (including Northeast Bimbi), Mpyupyu, Mposa, and Halala, at 1.0%, 1.5%, and 3.0% THM cut-offs (AMC,2023).

 

8.2CURRENT Exploration

 

CML’s drilling program at the Mposa Main (Mposa) target area commenced on 9 October 2023. The drilling program was designed to test the extent of potential mineralisation at depth as well as its lateral continuity by twinning selected existing holes as well as drilling further holes in the areas adjacent to Mposa. (Chilwa Minerals, 2024).

 

Sonic core drilling, using two Eijkelkamp CRS-V CompactRotoSonic rigs, was undertaken on the Mposa and Mpyupyu deposits (Chilwa Minerals, 2025a).

 

9.0Drilling

 

The MRE in June 2025 was based on the Sonic drilling undertaken by CML at the Mposa Main area, the Mpyupyu Dune area and Aircore drilling undertaken by previous project owners Mota Engil Investments (Malawi) Ltd (Chilwa Minerals, 2025a).

 

Drilling was spaced 25m across-strike and 100m along strike for most of the targets in the Chilwa project area. Except for Mposa and Mpyupyu Dune, the Sonic drilling was on a nominal 50 m across strike and 50m along strike grid (Chilwa Minerals, 2025a).

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

Drilling techniques for Aircore drilling have been previously reported as a component of the resource estimated by AMC (2023).

 

Drilling techniques for more recent sonic drilling, used for the Mposa and Mpyupyu deposit resource estimates are as follows (Chilwa Minerals, 2025a):

 

Drilling physicals are the same for both sonic rigs used.

 

Drilling was undertaken using a single barrel (CB3 SW CoreBarrel 2m), which produced core of Inner Diameter (ID) = 76mm and Outer Diameter (OD) = 102mm). Where waterlogged sediment or loose sediment was encountered, an Aqualock (AL70) Sampler 2m barrel was used, which produced core of Inner Diameter (ID) = 70mm and Outer Diameter (OD) = 92mm.

 

Drill rods were 1m in length.

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

10.0SAMPLE PREPARATION, ANALYSES, AND SECURITY

 

10.1Sample Preparation

 

The estimation relies on data from two distinct exploration phases, being the recent work undertaken by Chilwa Minerals, utilising sonic rigs to extract core for Heavy Liquid Separation (‘HLS’) assay (sonic), and the 2014-2016 work undertaken by previous owners MEIML, utilising Aircore rigs as the principal means of capturing samples for HLS assay (Aircore) (Chilwa Minerals, 2025a).

 

Aircore sampling and sub-sampling techniques included:

 

At a core yard, entire samples were placed in drying pans and sun-dried. Due to high clay content, many of the dried samples were cemented and required manual disaggregation using a mortar and pestle setup consisting of a steel bin and an RC blast hole bit welded to a steel pipe. The disaggregated material was weighed and then riffle-split multiple times using a 50-50 riffle splitter to obtain approximately 1 kg of representative sub-sample for submission to SGS (AMC,2023).

 

Sample representivity was ensured through field duplicates generated from the final split of randomly selected samples—one in every 20. Additionally, blanks, site-constructed reference samples, and umpire samples (5% replication) were inserted per batch to monitor data quality. The final 1 kg sample, produced using proper riffle splitting techniques, is considered representative, comprising roughly 10% of the original parent sample (Chilwa Minerals, 2025a).

 

Sonic sampling and sub-sampling methods included:

 

Prior to the commencement of drilling, logging, and sampling, the geological team developed a standardized set of protocols and procedures. Sonic core drilling, using two Eijkelkamp CRS-V CompactRotoSonic rigs, was undertaken. The core was logged, as a first pass, at the rig, then relogged and sampled at the Chilwa base camp, located in Zomba. Sampling was based on geological changes observed in the core, with a standard sample length of 1.0 m. Samples were first subject to sample preparation at the Company’s facility in Zalewa, Malawi, with the aim of generating a representative split sub-sample of 500g for Heavy Liquid Separation assay at ALS Laboratory in Perth, Australia and, from 2025, to LightDeepEarth Laborarory (LDE), in Pretoria, South Africa (Chilwa Minerals, 2025a).

 

Sample preparation involved initial drying, then crushing to 80% passing 3mm, followed by splitting of a sub-sample on a rotary splitter. The sub-sample (approximately 500g) was sent by air freight to LDE where it was analysed for slimes %, Oversize % and THM %. The Qualified person is of the opinion that the sampling techniques were to industry accepted standards (Chilwa Minerals, 2025a).

 

24

 

 

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

The core was logged and sampled at Chilwa base camp in Zalewa. Lose material was split using a scoop after having been homogenized; more competent core was split in the middle using a trowel or chisel. One half of the sample was bagged and labelled for submission and the other half stored on site in a plastic bag.

 

Blanks (5%), site-produced reference material (High and Low standards (5%) as well as duplicates (5%) were added to outgoing sample batches (Chilwa Minerals, 2025a).

 

10.2Analyses

 

The samples were sent for Heavy Liquid Separation assay at ALS Laboratory in Perth, Australia and, from 2025, to LightDeepEarth Laboratory (LDE), in Pretoria, South Africa (Chilwa Minerals, 2025a).

 

Heavy liquid separation (sink-float) was the assay method for all assays used in the MRE. Samples are received and reconciled against the client list, weigh and dry mass recorded. Samples are then soaked to allow complete wetting of clay minerals and then subject to light attrition scrubbing for clay dispersion. Material is then deslimed with the sub 45 µm fraction discarded, then dried and screened on 1 mm. + 1 mm mass is recorded as well as mass of 45 to 1,000 µm fraction. Prepare sand samples are then split to achieve mass circa 300 g which is submitted to sink-float using tetrabromoethane. Sink and Float fractions are cleaned with acetone and weighed (Chilwa Minerals, 2025a).

 

XRF, or X-ray fluorescence, analysis was used to determine the chemical composition of heavy mineral concentrates, including chemistry relevant to titanium, zirconium and associated mineral components. QEMSCAN, or Quantitative Evaluation of Minerals by Scanning Electron Microscopy, was used to determine the mineralogical composition of heavy mineral concentrates by identifying and quantifying the mineral phases present in the concentrates. The qualified person used XRF and QEMSCAN results together to support the interpretation of the THM assemblage, the estimation of the reported “Mineral in ROM” values, and the assessment of mineralogical continuity. QEMSCAN analyses performed by SGS were used in the June 2025 estimates, and QEMSCAN analyses performed by LightDeepEarth Laboratory for Mposa composite samples, with results received on November 13, 2025, were used in the Mposa Mineral Resource estimate update.

 

10.3Quality Assurance and Quality Control (QAQC)

 

AMC (2023) found in 2016 that the laboratory results from SGS compared with the standards and the umpire laboratory (AML), the slimes were high biased and the THM were low biased. Most of the samples were resampled as shown in Table 6 below. The QAQC was not done on the resampled data (AMC,2023).

 

Table 6. Resampled statistics (AMC,2023).

Sample representivity was ensured through field duplicates generated from the final split of randomly selected samples—one in every 20. Additionally, blanks, site-constructed reference samples, and umpire samples (5% replication) were inserted per batch to monitor data quality. The final 1 kg sample, produced using proper riffle splitting techniques, is considered representative, comprising roughly 10% of the original parent sample (Chilwa Minerals, 2025a).

 

The statistics of the Mposa deposit were compared between the aircore samples (94% resampled) and the sonic samples and they correlate very well with only higher variances within the sonic samples (Table 7) (Chilwa Minerals, 2025a).

The QAQC analyses on the Mposa sonic drill hole samples, were done on the field duplicates, the standards, the blanks and the laboratory repeats and the summary results were as follow (Chilwa Minerals, 2025a):

 

The summary of the field duplicates is shown in Table 8. The reason for the marginal precisions were their very low values (Chilwa Minerals, 2025a).

As has previously been reported, a subset of samples from the historic Aircore program (2015) were found to have been compromised by insufficient turnaround in sieves used at SGS laboratories. Compromised samples were identified and resampled. The MRE reported is based on the resampled data.

 

A visit to LDE laboratory was undertaken by Mr Bertus Cilliers November 2023. It is the Qualified persons’ opinion that the independent QAQC program has demonstrated that acceptable levels of accuracy and precision have been established.

 

11.0Data verification

 

Verification includes the following (Chilwa Minerals, 2025a);

 

Ensuring that all drill holes have appropriate XYZ coordinates.

 

Comparing the maximum depth of the hole against the final depth indicated in the collar file.

 

Comparing the final depth in the survey file against final depth in the collar file.

 

Comparing the final depths of all geology, assay, core recovery against the final depth in the collar file.

 

Checking for duplicate drill holes.

 

Validate tables against logging conventions defined per table in project definition e.g. check geology logs for gaps and overlaps or assay logs for just overlaps (gaps are allowed).

 

Checking that each depth interval has a main lithology.

 

Checking that all fields that were set up as mandatory fields contain entries.

 

Most of these validations protocols are generic come standard with database packages.

 

As a further check on the drill hole data supplied, it was imported into the Surpac modelling software. The data was validated for duplicates, gaps, overlaps, impossible intervals in down-hole sequence for assay, collar coordinates, geology data and survey data. The drill holes were also visually checked in plan (Figure 6, Figure 11, Figure 12, Figure 13, Figure 25, and Figure 26) and in the sections (Figure 7) in Surpac (Chilwa Minerals, 2025a).

 

The digital terrain model (DTM) created over the project areas from Lidar surveys, confined the boundary of the drill holes used and the block model. All the drill holes constrained in the DTM covered areas were draped onto its surfaces to determine the elevations (Z) of the coordinates. For the Chilwa North Deposits (Nkotamo, Halala, Beacon and Namanja West) the surveyed collars were used (Chilwa Minerals, 2025a).

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

Sampling techniques and data were reviewed by the previous Qualified person Mr Mark Burnett during a site visit completed in January 2025. The Qualified person’s review did not reveal any fatal flaws. The sampling and data collection techniques are considered to be industry standard.

 

A site visit to the exploration activities on the shores of Lake Chilwa, as well as the sample preparation facility at Zalewa was conducted in August 2025 by Bertus Cilliers. During the site visit the primary mineralization targets on both the western and northern shore of Lake Chilwa were visited.

 

During this site visit, all aspects of the exploration program were directly observed by the Qualified Person
  
Observations of the drilling highlighted the excellent sample recoveries achieved by the sonic drilling method
  
Logging of the sonic drilling was observed in the field and no issues were observed with the implementation of the standard protocol
  
Sampling preparation and sub-sampling was observed in detail. No major flaws were identified.

 

It is the Qualified persons’ opinion that the data used for the mineral resource estimates were adequate for the purposes used for the reporting in this technical report summary.

12.0Mineral Processing and Metallurgical Testing

 

Several metallurgical studies were completed by SGS, Mintek, AML and LDE on representative samples from the HMS deposits of the Lake Chilwa project. Detailed reports are available for the studies. The studies show that the mineralized sand from the HMS deposits can be processed into high grade ilmenite and zircon products with high recovery rates (Chilwa Minerals, 2025a).

 

12.1Mining method

 

The deposit characteristics, being predominantly unconsolidated sand in an area where the water table can be managed, are suited to dry mining with heavy earth moving equipment. Consequently, a dry mining method with a font end loader is preferred for the project concept as this allows for more flexibility than many other mining techniques and is better suited to mining of high slimes deposits (TZMI. 2015).

 

12.2Processing

 

For the concept study, TZMI reviewed various metallurgical reports detailing test work programs aimed at evaluating samples from the Halala, Mpyupyu and Mposa deposits. The processing and mineral separation concepts have been based on TZMI’s interpretation of the test work results combined with recognized industry benchmarks and standards (TZMI. 2015).

 

Three test work programmes were completed at different laboratories, including (TZMI. 2015):

 

SGS, South Africa: SGS is an analytical laboratory providing services to the mining industry. Two bulk composites were prepared from drill samples for evaluation.

 

Mintek, South Africa: Mintek is the Mineral Research Council of South Africa and provides test work and assessment services from their premises in Johannesburg, South Africa. Two bulk composites were prepared for initial flowsheet evaluation and sample characterization.

 

Allied Mineral Laboratories (AML), Western Australia: AML is a specialist mineral processing laboratory with specific experience and expertise in the processing of samples from mineral sands deposits. Two samples of approximately 20 kg each were provided for the purpose of assessing product characteristics.

 

The following conclusions were drawn based on the metallurgical test work results (TZMI. 2015):

 

The samples were highly variable in particle sizing and therefore separation response;

 

Gravity separation of the sand fractions using conventional equipment showed high separation efficiency;

 

29

 

 

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

Ilmenite product could be produced from all the concentrates with a TiO2 content ranging between 50 and 53%. The TiO2 balance indicated that more than 90% of the TiO2 in the gravity concentrate could be recovered to this product stream;

 

Processing of the non-magnetic stream indicated that a product with a high ZrO2 grade could be isolated;

 

Optical microscopy on samples generated by AML, indicated that some of the zircon in the tailings did have coatings and the impact of this on potential product recovery will have to be assessed.

 

A high-level flow diagram of the proposed process flowsheet for producing ilmenite and zircon concentrate as per the baseline project concept is shown in the following schematic (Figure 8) (TZMI. 2015).

 

 

 

Figure 8. High level process flowsheet (Ilmenite and zircon concentrate products), (TZMI. 2015).

 

The proposed operation will include a number of key stages (TZMI. 2015):

 

Mined ore is slurried and pumped to the primary concentrator plant (PCP) located at the mine site;
  
The Primary Concentrator Plant will consist of screening to remove coarse oversize, desliming to remove fines when necessary and gravity separation using spiral circuits to reject lighter gangue minerals;
  
A heavy mineral concentrate containing >90% HM is separated from the lower density sands, slimes and tailings.
  
The PCP tailings are pumped directly back into the mine void;

 

30

 

 

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

The HMC produced will be stockpiled adjacent to the PCP for loading onto haul trucks which will transport the concentrate to the mineral separation plant (MSP) at Liwonde;

 

The concentrate will be fed into the MSP where it will be dried and passed over magnetic and gravity separation stages to produce a magnetic ilmenite product and a zircon-rich non-magnetic concentrate;
  
The ilmenite and zircon concentrate products will be stored in a warehouse prior to being transported to the Nacala port by rail for exporting in bulk by ship.

 

The composition of the wet concentrator tailings, which make up the greatest volume of the tailings streams, is unchanged by the process and immediately returned to the back end of the mining void for stacking and re-profiling. Tailings streams produced at the MSP will be stockpiled and returned to the mine void via the haul trucks that are used to transport the HMC from the mine. The MSP tailings will be co-disposed with the wet concentrator tailings. TZMI has estimated product recovery figures for this study based on typical values experienced across the mineral sands industry and modified based on the outcome of the sighter evaluation work that has been completed. From this indicative flowsheet recoveries were modelled to provide the base for the concept study evaluation. The following table provides the mineral recovery figures which have been assumed for the proposed feed preparation circuit (TZMI. 2015).

 

Table 12. Process design criteria for Primary concentrator Plant (TZMI. 2015).

 

  Coarse Material Fine Material
HMC yield (% of feed) 3-5% 2-4%
HMC grade (% heavy mineral) 88-90% 88-90%
HM recovery to HMC 85-90% 85-90%
TiO2 recovery to HMC >95% >90%
ZrO2 recovery to HMC >95% >95%

 

The following preliminary process design assumptions have been used for the Mineral Separation Plant assuming production of an ilmenite product, with a zircon concentrate (TZMI. 2015).

 

Table 13. Process design criteria – Mineral Separation Plant (TZMI. 2015).

 

Primary Magnetic separation
  Coarse Material Fine Material
MSP TiO2 recovery to ilmenite product 90-95% 90-95%
TiO2 grade in ilmenite product 51-53% 51-53%
Non-Magnetic circuit
  Coarse Material Fine Material
MSP ZrO2 recovery to zircon concentrate 90-95% 90-95%
MSP ZrO2 recovery to zircon product 75-80% 70-75%

 

Process testwork indicated that the losses in the mineral separation plant were minimal for the production of ilmenite and a non-magnetic concentrate. However, significant losses would be incurred when producing a final zircon product as a more complex circuit will be required to reject contaminants from the zircon (TZMI. 2015).

 

All products from the MSP: ilmenite and zircon concentrate, are dry and will be transferred and shipped as dry product. Final products will be loaded from the load out bins and product stockpiles onto trains which will transport the final products a distance of 670km to similar product storage sheds located at the Nacala port (TZMI. 2015).

13.0Mineral Resource Estimate

 

13.1Modelling

 

Sectional interpretation was done on all the Chilwa Northern Deposits (Nkotamo, Halala, Beacon and Namanja West) and on the Mposa Deposit. On each section line the basal clay contact together with a 1% THM cut-off were modelled. These sectional interpretations were then wireframed to form DTM surfaces. The basal clay contacts of Bimbi, Bimbi NE and Mpyupyu used, was modelled by AMC (Chilwa Minerals, 2025a).

 

13.2Statistical Analysis

 

Univariate statistical analysis was carried out on the variables, THM %, Slimes % and Oversize % of the 1 m composited drill hole data on all the deposits in the June 2025 estimations, using Excel and Surpac (Chilwa Minerals, 2025a).

 

Reflecting an overall change in strike from NNE to NE over the 8km of strike of the Mposa deposits, three mineralised domains were created in the Novermber 2025 update, Main NE, Main SW (together referred to as Mposa Main) and Mposa North, that were formed along the northwestern edge of Lake Chilwa. Univariate statistical analysis was carried out on the variables, THM %, Slimes % and Oversize %, HfO₂ %, TiO₂ %, and ZrO₂ % of the 1m composited drill hole data using Excel and Surpac for each domain (Chilwa Minerals, 2025b).

 

13.3Variography

 

The inverse distance method for grade interpolation was used for the project area, with the estimation parameters derived from calculated variograms. The estimation parameters for the June 2025 estimations were summarized in Table 16 and in Table 17 for the Mposa deposits update. Variograms were modelled for the following variables: THM %, Slime % and Oversize % from the composite data for each deposit area: Mposa NE and SW, Mpyupyu, Bimbi, Bimbi NE and Chilwa North. Variograms were calculated in Surpac with the composite data, and the following is a summary of the procedures followed (Chilwa Minerals, 2025a and 2025b):

 

Variograms were calculated on all the composite data for their respective deposit area.

 

The variogram directions or ellipsoid bearings were chosen as the best fit variogram with their plunges and dip as horizontal.

 

13.4Mineral assemblages

 

13.4.1Mineralogy

 

Mineralogy has been undertaken on THM concentrates using chemical data obtained using XRF combined with QEMSCAN analysis (Chilwa Minerals, 2025b).

Ilmenite can be expressed as (Fe,Mg,Mn)TiO3. With alteration and natural weathering of ilmenite, the removal of Fe, resulting in the formation of alteration minerals with increased Ti-contents relative to that of ilmenite. The minerals such as pseudorutile, ferropseudobrookite and anatase were generally grouped under leucoxene (Table 15 and Figure 9). Generally, the term “leucoxene” is used in the heavy minerals industry as a collective description for ilmenite alteration products with TiO2-components ranging from 65-90%. (Wallmach et al, 2008). Rutile is 100 % TiO2.

 

Table 15: Ilmenite and associated minerals (Wallmach et al, 2008).

 

Mineral Formula Theoretical TiO2-content
Ilmenite Fe2+TiO3 52.7%
Pseudorutile Fe3+2Ti3O9 60.0%
Ferropseudobrookite Fe2+Ti2O5 69.0%
Rutile TiO2 100.0%

13.4.5Almandine Garnet

 

Almandine (Fe₃Al₂Si₃O₁₂) is the most common member of the Garnet group. Almandine is an iron aluminum silicate. The iron is sometimes partially replaced with magnesium and manganese. The variable formula for almandine: (Fe,Mg,Mn)₃Al₂Si₃O₁₂ (https://www.minerals.net/mineral/almandine.aspx).

 

13.4.6XRF and QEMSCAN Analysis

 

The XRF and QEMSCAN analysis was done to determine the mineralogy for the heavy mineral concentrates. SGS (2018) did QEMSCAN analysis that were used in the June 2025 estimates (Chilwa Minerals, 2025a).

 

LDE laboratory did QEMSCAN analysis for composite samples of the Mposa deposits with results received November 13, 2025, that were used in the Mposa MRE update (Chilwa Minerals, 2025b).

 

13.5Block Modelling and Grade Estimation

 

Block models with block sizes of 100m X 100m X 1m and minimum sub blocking of 25m X 25m X 0.5m were created within Surpac for all the HMS deposits in the June 2025 estimations (Chilwa Minerals, 2025a).

 

A new block model with block sizes of 50m X 50m X 0.5m without sub blocking was created within Surpac for the Mposa deposits in the November 2025 update (Chilwa Minerals, 2025b).

 

13.6Grade Estimation Plan and Parameters

 

Inverse distance with the power of 3 was used for in situ grade interpolation for the THM %, Slime % and Oversize % with the 1m composites within their respective ore domains in the June 2025 estimations for all the deposits (Chilwa Minerals, 2025a).

 

Inverse distance with the power of 2.5 was used for in situ grade interpolation for the THM %, Slime %, Oversize %, HfO₂ %, TiO₂ %, and ZrO₂ % with the 1m composites within their respective ore domains in the November 2025 estimation update for the Mposa deposits (Chilwa Minerals, 2025b).

 

All the estimation parameters used, derived from the variography, are listed in Table 16 and Table 17 for the June 2025 and November 2025 estimates respectively (Chilwa Minerals, 2025a and 2025b).

 

A three-pass grade interpolation plan was used. General aspects of the estimation are as follows (Chilwa Minerals, 2025a and 2025b):

 

A minimum of 3 samples and a maximum of 15 samples were used for all inverse distance runs;

 

Pass 1: search radii set to the range in the variogram for major and 20m for vertical;

 

Pass 2: search radii set to 1.5 times the range in the variogram for major and 30m for vertical;

 

Pass 3: search radii set to 1000m for major and 50m for vertical to estimate all the blocks;

 

35

 

 

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

With the THM % estimation, the blocks were flagged = 1 after the first inverse distance run or pass1, flagged = 2 after pass 2 and flagged = 3 after pass 3;

 

Block discretisation was set to 4(X) by 4 (Y) by 4 (Z);

 

An octant search estimation method was used with the maximum of 3 adjacent empty octants in pass 1, a maximum of 5 adjacent empty octants in pass 2 and a maximum of 7 adjacent empty octants in pass 3;

 

No sample limits per drill hole were applied.

 

The following were conduted in the November 2025 update for the Mposa deposits (Chilwa Minerals, 2025b):

 

Pass 1: search radii set to the range in the variogram for major and 6m for vertical;

 

Pass 2: search radii set to 1.5 times the range in the variogram for major and 9m for vertical;

 

Pass 3: search radii set to 300m for major and 20m for vertical to estimate all the blocks;

 

The parameters of the THM % were used for the estimations of HfO₂ %, TiO₂ %, and ZrO₂ % for their respective Mposa Main NE and SW domains except in the QEMSCAN zone of MPO-C09.

 

The parameters of Mposa NE were used for the Mposa North deposit.

13.8.1Visual Validation

 

The visual check on the block model sections generally correlates well with the input data. The blocks were coloured according to the THM % in the legend to compare with the drill holes with the same colour intervals (Figure 14 to Figure 22) (Chilwa Minerals, 2025a and 2025b).

13.8.2Average Grade Conformance

 

Comparisons of global average input composite data with the block model estimated grades of all the deposits in the June 2025 estimates compare reasonably well (Table 19). The higher difference in the THM % of Mposa was probably related to the high variances within the sonic samples (Chilwa Minerals, 2025a).

Comparisons of global average input composite data with the block model estimated grades of all the deposits or domains of Mposa November 2025 update compare reasonably well (Table 20. The higher differences in Mposa North were probably related to the greater drilling grid of 200m x 50m (Chilwa Minerals, 2025b).

13.8.3Swath Plot Check

 

The average grade conformance is a global representation over the entire domain. To assess average grade conformance progressively across the deposits, swath plots were used. In these plots, both data and model estimates are averaged into Easting, Northing and RL slices and the conformance of grade is assessed for each slice, in a particular direction. Swath plots, QQ plots and Scatter plots were run for all the 9 deposits. The overall grade conformance on the swath plots was acceptable, and it can be seen in the plots that the trends of the block means follow the sample means closely (Chilwa Minerals, 2025a and 2025b).

 

13.9 Cut-off grade

 

The 1.0% THM cut-off grade was selected by the qualified person based on the relationship between estimated operating cost per tonne of run-of-mine material and estimated recoverable revenue per tonne of run-of-mine material. The break-even cut-off grade is calculated as:

 

Break-even THM cut-off grade (%) = Estimated operating cost per tonne ROM ÷ Estimated recoverable revenue per tonne ROM generated by each 1.0% THM.

 

Estimated operating cost per tonne ROM includes mining cost, processing cost, site general and administrative cost, and other operating cost assumptions considered relevant by the qualified person. The unit operating cost for the base case model have been estimated at approximately US$8.65 per tonne by TZMI in 2015 (TZMI, 2015) (Figure 23). These 2015 costs were escalated on a yearly basis up to the year 2030. The average of the escalated costs for the period 2026 to 2030, equal to US$12.71 per tonne, was then used in the break-even calculation. Estimated recoverable revenue with the 1.0% THM cut-off and with a 90% recovery, were US$12.27 per tonne for the period to 2030 based on the applicable recovery assumptions (TZMI, 2015), and the commodity price assumptions (TZMI, 2026) for sulphate ilmenite, zircon, rutile and monazite. Based on the assumed operating costs, recoveries and commodity prices described in this technical report summary, the qualified person concluded that a 1.0% THM cut-off grade is reasonable for reporting Mineral Resources with reasonable prospects for eventual economic extraction. The 1.0% THM cut-off grade does not establish mineral reserves and should not be read as demonstrating economic viability.

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

14.0resource classification

 

The resource classification was primarily based on the drill hole density. The passes were used in the classification process. With the THM % estimation, the blocks were flagged = 1 after the first inverse distance run or pass1, flagged = 2 after pass 2 and flagged = 3 after pass 3 (see Section 13.6). The flagged 1 and 2 blocks were classified as Indicated and the flagged 3 blocks were assigned as Inferred in the June 2025 estimations. In the November 2025 Mposa update, the flagged 1 and some flagged 2 blocks were classified as Measured and the flagged 2 and 3 blocks were classified as Indicated. The coverage of the QEMSCAN samples were taken into consideration as the mineral assemblages in the THM were based on it. All the Mineral Resources were classified as Indicated except for Mposa, Bimbi NE and Mpyupyu. (Figure 24 to Figure 26) (Chilwa Minerals, 2025a and 2025b). The Measured Mineral Resource classification at Mposa was established by the qualified person based on all the estimated data derived from resent sonic drilling together with the good coverage of the QEMSCAN samples. At Mposa, approximately 83% of the Mineral Resources were classified as Measured and the remainder as Indicated The other deposits estimated with data derived from older air core drilling campaigns were classified as Indicated and Inferred. These are currently all being redrill with sonic drilling to be re-estimated for higher confidence categories.

 

The uncertainty associated with the Mineral Resource estimate varies by classification category. Measured Mineral Resources have the highest level of geological confidence and are supported by closer-spaced drilling, more complete mineralogical support, stronger grade-continuity evidence, and more robust QA/QC and database validation. Indicated Mineral Resources have a lower but sufficient level of confidence to support the application of technical and economic factors for purposes of assessing reasonable prospects for economic extraction. Inferred Mineral Resources have the lowest level of geological confidence and are based on more limited geological evidence and sampling. Inferred Mineral Resources are too speculative geologically to have modifying factors applied to them in a manner that would permit categorization as mineral reserves, may not be used to support economic viability, and may not be converted directly to mineral reserves.

15.0resource statement

 

The in situ Mineral Resource estimations reported from the block model with a 1.0% THM cut-off, are shown below for the project area (Table 21). The 1.0% THM reporting cut-off reflects the qualified person’s break-even assessment based on the estimated operating cost, metallurgical recovery and commodity price assumptions described in the Technical Report Summary. For the cut-off grade equation and the underlying inputs, see Section 13.9 of the Technical Report Summary. The HM recovery to HMC recovery is from 85% to 90% (TZMI, 2015).

 

Commodity price assumptions used in the Mineral Resource estimate

 

The following commodity price assumptions were used by the qualified person in preparing the Mineral Resource estimate. The prices are stated in Real 2025 US dollars on an FOB basis and are used solely for purposes of assessing reasonable prospects for eventual economic extraction in connection with the Mineral Resource estimate. They are not forecasts by the Company and do not establish mineral reserves or demonstrate economic viability.

 

Commodity Long-term price assumption Point of reference Notes
Sulphate ilmenite US$255 per tonne FOB Long-term price assumption used for mineral resource estimation
Zircon US$1,504 per tonne FOB Long-term price assumption used for mineral resource estimation
Rutile US$1,425 per tonne FOB Long-term price assumption used for mineral resource estimation
Monazite US$5,350 per tonne FOB Long-term price assumption used for mineral resource estimation

****Not separately estimated. The mineral is included within THM but has not been estimated separately for this deposit due to insufficient mineralogical support.” The Mposa (Main) and Mposa (North) rows keep their existing leucoxene, garnet and monazite values — those are the deposits with QEMSCAN support.

 

THM means total heavy minerals and represents the total heavy mineral content as a percentage of run-of-mine material. The “Mineral in ROM” columns express the grade of each individual mineral as a percentage of run-of-mine material. Accordingly, the sum of the individual “Mineral in ROM” columns for ilmenite, zircon, leucoxene, rutile, garnet and monazite represents the reported valuable heavy mineral assemblage within the broader THM grade, while the balance of THM comprises other heavy minerals that are not separately reported as planned products. For example, for the Mposa (Main) Measured Mineral Resource, the reported THM grade of 4.4% includes ilmenite at 3.00%, zircon at 0.39%, leucoxene at 0.40%, rutile at 0.04%, garnet at 0.12% and monazite at 0.02% of run-of-mine material, for a reported valuable heavy mineral assemblage of approximately 3.97% of run-of-mine material, with the balance comprising other heavy minerals.

 

Inferred mineral resources are subject to uncertainty as to their existence and as to their economic and legal feasibility. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for the evaluation of economic viability. For the meanings of certain technical terms used in this prospectus, see “Glossary of Terms.”

 

We have no mineral reserves. Mineral resources are not mineral reserves and do not have demonstrated economic viability. Inferred mineral resources are subject to uncertainty as to their existence and as to their economic and legal feasibility, and are too speculative geologically to have economic considerations applied to them in a manner that would permit categorization as mineral reserves. For the meanings of certain technical terms used in this prospectus, see “Glossary of Terms.”

 

In the opinion of the qualified person, the principal technical and economic factors likely to influence the prospect of economic extraction for the reported Mineral Resources include drilling density, geological and grade continuity, THM assemblage, slimes and oversize content, product specifications, metallurgical recovery, mining and processing cost assumptions, infrastructure access, environmental and permitting requirements, and market assumptions. Subject to the limitations and uncertainties described in this technical report summary, the qualified person believes that the issues relating to these factors are capable of being further evaluated through additional drilling, mineralogical and metallurgical test work, QAQC and database validation, engineering studies, environmental baseline work and future technical studies. This opinion does not constitute a determination of mineral reserves and does not demonstrate economic viability.

CHILWA MINERALS - TECHNICAL REPORT SUMMARY

 

16.0Conclusion and recommendations

 

Under the assumptions presented in this Report, the Chilwa Minerals Sand Project represents a substantial Mineral Resource that warrants technical evaluation and studies.

 

It is the qualified person’s opinion that additional work is justified on the Project to upgrade the mineral resource confidence categories that are relevant to the technical and economic factors likely to influence the prospect of economic extraction.

 

Belenos recommended the following:

 

Infill drilling in the Inferred and Indicated areas to increase the confidence level to higher categories.

 

XRF and QEMSCAN analysis in areas that that are not well covered to increase the confidence level to higher categories.

 

Use the QEMSCAN data to estimate the garnet values in the block models.

 

Updating the resource models periodic per deposit area as soon as all the new drilling assay and QEMSCAN data are available per deposit area.

 

Define the optimum modelling THM % together with a maximum Slimes % from the metallurgical testings for the economic mining process and re-model the base clay footwall on all deposits accordingly.
