Nature of operations

Goldgroup Mining Inc. is the parent company of its consolidated group ("Goldgroup'' or the "Company''). Goldgroup was incorporated in Quebec under the Business Corporations Act (Québec) and on July 28, 2011 it was continued under the Business Corporations Act (British Columbia). Its head office is located at Suite 410 – 1111 Melville St., Vancouver BC, V6E 3V6. Goldgroup together with its subsidiaries, is a Canadian-based gold producer and is focused on the acquisition, exploration and development of advanced stage gold-bearing mineral properties in the Americas. The Company’s current gold production and exploration and development related activities are conducted in Mexico. Goldgroup owns a property portfolio that includes a 100% interest in the operating Cerro Prieto project in Sonora. The Company is listed on the Toronto Venture Exchange (“TSX-V”) under the “GGA” trading symbol.

Going Concern

The Company has experienced recurring operating losses and has an accumulated deficit of $220,640 as at March 31, 2026. In addition, as at March 31, 2026, the Company has working capital deficiency of $30,947. Working capital is defined as current assets less current liabilities and provides a measure of the Company’s ability to settle liabilities that are due within one year with assets that are also expected to be converted into cash within one year. The Company’s ability to continue as a going concern is dependent upon its ability to generate future profitable operations and/or to obtain the necessary financing to conduct its planned work program on its mineral properties, meet its on-going levels of corporate overhead and commitments, keep its properties in good standing and discharge its liabilities as they come due. These matters result in material uncertainties which may cast significant doubt about the Company’s ability to continue as a going concern. These condensed interim consolidated financial statements do not include any adjustments that would be necessary if the going concern assumption were not appropriate. If the going concern basis was not appropriate for these condensed interim consolidated financial statements, then adjustments would be necessary in the carrying value of assets and liabilities, the reported revenues and expenses, and the classifications used in the statement of financial position.

Recent global issues, including political conflict in other regions, have adversely affected workplaces, economies, supply chains, and financial markets globally. It is not possible for the Company to predict the duration or magnitude of the adverse results of these issues and their effects on the Company's business or results of operations at this time.

These condensed interim consolidated financial statements have been prepared in accordance with IAS 34 – Interim Financial Reporting as issued by the International Accounting Standards Board (“IASB”). Accordingly, certain disclosures included in annual financial statements prepared in accordance with IFRS Accounting Standards (“IFRS”) as issued by the IASB have been condensed or omitted and these condensed interim consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2025.

The accounting policies applied in these condensed interim consolidated financial statements are consistent with those applied and disclosed in the Company’s audited financial statements for the year ended December 31, 2025.

The Company’s interim results are not necessarily indicative of its results for a full year.

These condensed interim consolidated financial statements were approved by the Board of Directors on June 1, 2026.

The preparation of financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

The Company’s management makes judgments in its process of applying the Company’s accounting policies in the preparation of its condensed interim consolidated financial statements. In addition, the preparation of the financial data requires that the Company’s management make assumptions and estimates of the effects of uncertain future events on the carrying amounts of the Company’s assets and liabilities at the end of the reporting period and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates as the estimation process is inherently uncertain. Estimates are reviewed on an ongoing basis based on historical experience and other factors that are considered to be relevant under the circumstances. Revisions to estimates and the resulting effects on the carrying amounts of the Company’s assets and liabilities are accounted for prospectively.

Significant judgments in applying accounting policies

The critical judgments that the Company’s management has made in the process of applying the Company’s accounting policies, apart from those involving estimations, that have the most significant effect on the amounts recognized in the Company’s condensed interim consolidated financial statements are as follows:

The carrying value of property, plant and equipment and the Company’s mineral property is reviewed each reporting period to determine whether there is any indication of impairment. If the carrying amount of an asset exceeds its recoverable amount, the asset is impaired and an impairment loss is recognized in profit or loss. The assessment of fair values, including those of the cash-generating units, require the use of estimates and assumptions for recoverable production, long-term commodity prices, discount rates, foreign exchange rates, future capital requirements and operating performance. Changes in any of the assumptions or estimates used in determining the fair value of assets could impact the impairment analysis.

Management applies judgment in assessing whether facts and circumstances indicate that the carrying amount of exploration and evaluation assets may exceed their recoverable amount. In making this assessment, management considers, among other matters, the period for which the entity has the right to explore in the specific area, plans for further exploration and evaluation, the results of exploration work to date, whether substantive expenditure on further exploration is budgeted or planned, and whether data exists that suggest the carrying amount is unlikely to be recovered in full from successful development or by sale. The use of judgment is particularly important in the early stages of a project where limited information may be available.

Management has determined that exploratory drilling and evaluation costs incurred which have been capitalized are economically recoverable. Management uses several criteria in its assessments of economic recoverability and probability of future economic benefit including geologic and metallurgic information, history of conversion of mineral deposits to proven and probable reserves, scoping and feasibility studies, accessible facilities, existing permits and life of mine plans.

The functional currency for each of the Company and it’s subsidiaries is the currency of the primary economic environment in which the entity operates. The Company has determined the functional currency of each entity is the US dollar. Determination of functional currency may involve certain judgments to determine the primary economic environment and the Company reconsiders the functional currency of its entities if there is a change in events and conditions which determined the primary economic environment.

Key sources of estimation uncertainty

The areas which require management to make significant estimates and assumptions in determining carrying values include, but are not limited to:

The carrying value and recoverability of mineral properties requires management to make certain estimates, judgments and assumptions about each project. Management considers the economics of the project, including the latest resources prices and the long-term forecasts, and the overall economic viability of the project. The determination of mineral resources also requires the use of estimates. The Company estimates its mineral resources based on information compiled by Qualified Persons as defined in accordance with Canadian Securities Administrators National Instrument 43-101, Standards for Disclosure of Mineral Projects. There are numerous uncertainties inherent in estimating mineral resources and assumptions that are valid at the time of estimation which may change significantly when new information becomes available. Changes in the forecasted prices of commodities, exchange rates, production costs or recovery rates may change the economic status of resources and may result in changes to resource estimates.

Plant and other facilities used directly in mining activities are depreciated using the unit-of-production (“UOP”) method over a period not to exceed the estimated life of the ore body based on recoverable ounces to be mined from estimated resources. Mobile and other equipment are depreciated, net of residual value, on a straight-line basis, over the useful life of the equipment to the extent that the useful life does not exceed the related estimated life of the mine based on estimated recoverable resources.

The calculation of the UOP rate, and therefore the annual depreciation and depletion expense, could be materially affected by changes in the underlying estimates. Changes in estimates can be the result of actual future production differing from current forecasts of future production, expansion of mineral reserves through exploration activities, differences between estimated and actual costs of mining and differences in gold price used in the estimation of mineral reserves.

Significant judgment is involved in the determination of useful life and residual values for the computation of depreciation and depletion and no assurance can be given that actual useful lives and residual values will not differ significantly from current assumptions.

The Company assesses its provision for reclamation and remediation on an annual basis or when new material information becomes available. Mining and exploration activities are subject to various laws and regulations governing the protection of the environment. In general, these laws and regulations are continually changing and the Company has made, and intends to make in the future, expenditures to comply with such laws and regulations. Accounting for reclamation and remediation obligations requires management to make estimates of the future costs the Company will incur to complete the reclamation and remediation work required to comply with existing laws and regulations at each mining operation and exploration and development property. Actual costs incurred may differ from those amounts estimated. Also, future changes to environmental laws and regulations could increase the extent of reclamation and remediation work required to be performed by the Company. Increases in future costs could materially impact the amounts charged to operations for reclamation and remediation. The provision represents management’s best estimate of the present value of the future reclamation and remediation obligation. The actual future expenditures may differ from the amounts currently provided.

Due to the size, complexity and nature of the Company’s operations, various legal and tax matters are outstanding from time to time. In the event that management’s estimate of the future resolution of these matters changes, the Company will recognize the effects of the changes in its consolidated financial statements on the date such changes occur.

In assessing the probability of realizing income tax assets recognized, management makes estimates related to expectations of future taxable income, expected timing of reversals of existing temporary differences and the likelihood that tax positions taken will be sustained upon examination by applicable tax authorities.  Estimates of future taxable income are based on forecasted cash flows from operations and the application of existing tax laws in each jurisdiction. Forecasted cash flows from operations are based on life of mine projections internally developed and reviewed by management.  The likelihood that tax positions taken will be sustained upon examination by applicable tax authorities is assessed based on individual facts and circumstances of the relevant tax position evaluated in light of all available evidence. Where applicable tax laws and regulations are either unclear or subject to ongoing varying interpretations, it is reasonably possible that changes in these estimates can occur that materially affect the amounts of income tax assets recognized. At the end of each reporting period, the Company reassesses unrecognized income tax assets.

The fair value of the warrant liabilities is determined using the Black-Scholes option pricing model, which requires the use of estimates and assumptions, including share price volatility, expected life, risk-free interest rate and expected dividends. Changes in any of the assumptions or estimates used in the valuation could impact the fair value of the derivative warrant liabilities and the amounts recognized in profit or loss.

Expenditures incurred, and depreciation and depletion of assets used in mining and processing activities are deferred and accumulated as the cost of ore in stockpiles, ore on leach pads, in-process and finished metal inventories. These deferred amounts are carried at the lower of average cost or net realizable value (“NRV”). Write-downs of ore in stockpiles, ore on leach pads, in-process and finished metal inventories resulting from NRV impairments are reported as a component of current period costs. The primary factors that influence the need to record write-downs include prevailing and long-term metal prices and prevailing costs for production inputs such as labour, fuel and energy, materials and supplies, as well as realized ore grades and actual production levels.

Costs are attributed to the leach pads based on current mining costs, including applicable depreciation and depletion relating to mining operations incurred up to the point of placing the ore on the pad. Costs are removed from the leach pad based on the average cost per recoverable ounce of gold on the leach pad as the gold is recovered. Estimates of recoverable gold on the leach pads are calculated from the quantities of ore placed on the pads, the grade of ore placed on the leach pads and an estimated percentage of recovery. Timing and ultimate recovery of gold contained on leach pads can vary significantly from the estimates. The quantities of recoverable gold placed on the leach pads are reconciled to the quantities of gold actually recovered (metallurgical balancing), by comparing the grades of ore placed on the leach pads to actual ounces recovered. The nature of the leaching process inherently limits the ability to precisely monitor inventory levels. As a result, the metallurgical balancing process is constantly monitored and the engineering estimates are refined based on actual results over time. The ultimate recovery of gold from a pad will not be known until the leaching process is completed.

The allocation of costs to ore on leach pads and in-process inventories and the determination of NRV involve the use of estimates. There is a high degree of judgment in estimating future costs, future production levels, reserves estimates, gold and silver prices, and the ultimate estimated recovery for ore on leach pads. There can be no assurance that actual results will not differ significantly from estimates used in the determination of the carrying value of inventories.

New accounting standards

IFRS 18, Presentation and Disclosure in Financial Statements

In April 2024, the IASB issued IFRS 18, Presentation and Disclosure in Financial Statements, which will replace IAS 1, Presentation of Financial Statements. IFRS 18 introduces new requirements for presentation within the statement of profit or loss, including defined categories and subtotals, and requires additional disclosure for certain management-defined performance measures. The standard also includes enhanced guidance on aggregation and disaggregation of information in the financial statements. IFRS 18 is effective for annual reporting periods beginning on or after January 1, 2027, with earlier application permitted. The Company is currently assessing the impact of IFRS 18 on its financial statements.

Fair values of financial instruments

The accounting classification of each category of financial instruments, and the level within the fair value hierarchy in which they have been classified are set out below:

Credit risk

Credit risk is the risk of an unexpected loss if a customer or third party to a financial instrument fails to meet its contractual obligations. Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash. The majority of the Company’s cash are held through large Canadian financial institutions. Receivables are primarily due from government agencies.

Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company manages liquidity risk through the management of its capital structure as described in note 21. The accounts payable and accrued liabilities, and current lease liability are due within the current operating period. The Company is exposed to liquidity risk.

Price risk

Price risk is the risk that the trading price of the Company’s shares will fluctuate and result in an increase or decrease in value of the warrant liability.

Commodity price risk

The Company is exposed to commodity price risk given that its revenues are derived from the sale of metals, the price of which have been historically volatile.

Interest rate risk

Interest rate risk is the risk that the fair value of future cash flows from a financial instrument will fluctuate because of changes to market interest rates. The Company is exposed from time to time to interest rate risk as a result of holding fixed income cash equivalents and investments, of varying maturities and loans payable. A 1% change in market interest rates would result in no significant change in value of cash or fixed income securities. The risk that the Company will realize a loss as a result of a decline in the fair value of these assets is limited as they are generally held to maturity.

Foreign exchange risk

The Company operates in Canada and Mexico and is exposed to foreign exchange risk arising from transactions denominated in foreign currencies.

The operating results and the financial position of the Company are reported in United States dollars. Fluctuations of the operating currencies in relation to the United States dollar will have an impact upon the reported results of the Company and may also affect the value of the Company’s assets and liabilities.

The Company’s financial assets and liabilities as at March 31, 2026 are denominated in United States Dollars, Canadian Dollars, and Mexican Pesos, and are set out in the following table:

Goldgroup Mining Inc.

(amounts expressed in thousands of US dollars, except where indicated - Unaudited)

The Company’s financial assets and liabilities as at December 31, 2025 are denominated in United States Dollars, Canadian Dollars, and Mexican Pesos, and are set out in the following table:

The Company’s reported results will be affected by changes in the US dollar to Canadian dollar and US dollar to Mexican Pesos exchange rate. As of March 31, 2026, a 10% appreciation of the Canadian dollar relative to the US dollar would have decreased net financial assets by approximately $3,334 (December 31, 2025 - $4,045). A 10% depreciation of the US Dollar relative to the Canadian dollar would have had the equal but opposite effect. A 10% appreciation of the Mexican Pesos relative to the US dollar would have decreased net financial asset by approximately $1,207 (December 31, 2025 -$1,196) and a 10% depreciation of the Mexican Pesos would have had an equal but opposite effect. The Company has not entered into any agreements or purchased any instruments to hedge possible currency risk.

The table below summarizes the maturity profile of the Company’s non-derivative financial liabilities.

On September 1, 2006, the Company entered into an Earn in/Option Agreement (“the Agreement”) with DynaResource de Mexico S.A. de C.V. (“DynaMexico”) and its parent company, DynaResource, Inc. (“DynaUSA”). Under the Agreement, the Company had the right to earn up to a 50% equity interest in DynaMexico by funding up to $18 million in exploration and development expenditures on the San Jose de Gracia property (“SJG”). On March 14, 2011, the Company completed its Earn in/Option Agreement with DynaMexico for its 50% equity interest by reaching the expenditure funding requirement of $18 million. Subsequent to this date there have been legal claims filed in Mexico and the United States which resulted in the foreclosure of the Company’s share ownership.

On October 13, 2015, the Company was made aware of a news release disseminated by DynaMexico which claimed DynaMexico was awarded a $48 million judgement against the Company’s subsidiary Goldgroup Resources Inc. The Company’s position in response to the $48 million claim is that the Company was never notified of the purported court case, and does not recognize any of the claims mentioned therein and is of the belief that such claims are entirely without merit. The Company pursued the case to the Mexican Supreme Court level to get the judgment overturned.

On December 6, 2019, the 11th Federal Circuit Collegiate Court in México denied Goldgroup’s amparo regarding the $48 million claim and on February 20, 2020 a Mexico City court issued a judgment in favour of DynaMexico.

On December 4, 2020, DynaMexico filed another claim seeking recognition of the judgment under the Texas Uniform Foreign-County Money Judgment Recognition Act. The Company filed a Special Appearance, Motion to Dismiss for Improper Venue, and Motion for Non-Recognition in response. A hearing was held on the Special Appearance and Motion to Dismiss for Improper Venue on February 8, 2021 and on May 12, 2021, the 134th Judicial District Court, as a District Court of the State of Texas, ruled it is not required to recognize DynaMexico’s foreign judgment from the country of Mexico. DynaUSA has appealed this decision and the appeal has been fully briefed and oral arguments were held on April 20, 2022. On May 2, 2023, the court of appeals dismissed DynaUSA’s appeal.

On March 6, 2023, the Company announced that its subsidiary, Goldgroup Resources, filed a Request for Arbitration on February 17, 2023 with the International Centre for Settlement of Investment Disputes (“ICSID”) against the United Mexican States. The treatment and inaction by the Mexican courts have resulted in a judicial expropriation of Goldgroup Resources’ investment in DynaMexico and a denial of justice in breach of Mexico’s obligations under the North American Free Trade Agreement (“NAFTA”). On February 7, 2024, Goldgroup Resources filed its Memorial on the Merits related to the NAFTA claim and received Mexico’s Counter Memorial on the Merits and Memorial on Jurisdiction on June 19, 2024. On December 12, 2024, Goldgroup Resources filed its Reply on the Merits and Counter Memorial on Jurisdiction and received Mexico’s Rejoinder on the Merits and Reply on Jurisdiction on April 28, 2025. On June 11, 2025, Goldgroup Resources filed its Rejoinder on Jurisdiction. On August 15, 2025, Goldgroup Resources and Mexico filed their respective Comments on the Non-Disputing Party Submissions filed by Canada and the United States of America pursuant to NAFTA Article 1128. On September 23, 2025, Goldgroup Resources’ damages experts filed a Supplemental Report on Quantum, and Goldgroup Resources received the Supplemental Report on Quantum of Mexico’s damages experts on November 18, 2025. Goldgroup Resources is seeking monetary damages as a result of Mexico’s breaches of NAFTA, as well as declarations from the arbitral tribunal to counter any potentially detrimental consequences stemming from the continued existence of the $48 million judgment issued by the Mexican courts in favour of DynaMexico.

The Company’s mining concessions have an existing 2% net smelter royalty (“NSR”).

During the year ended December 31, 2025, the Company acquired the San Francisco mine (Note 12). The San Francisco Mine is a large-scale, formerly producing open pit gold mine. The San Francisco Project encompasses concessions in the north central portion of the state of Sonora, Mexico, north of the state capital, Hermosillo.

The operation is comprised of two previously producing open pits (San Francisco and La Chicharra), together with heap leach processing facilities and associated infrastructure located close to the San Francisco pit.

The Company’s San Francisco mining Project has the following obligations owed to SA Targeted Investing Corp., a subsidiary of Royal Gold Inc. (“Royal Gold”):

(i) Gold Delivery: Commencing 5 (five) business days after restart of operations, and every month thereafter, deliver 75 gold ounces per month for 20 months; (Note 12)

(ii) Net Smelter Royalty: the Company will pay to Royal Gold a 1% NSR on each of the following mining concessions: San Francisco, Patricia, Norma, La Pima, Dulce, and San Judas. The NSR will commence once the Gold Delivery obligation is complete.

On August 13, 2024, the Company entered into an agreement (the “Agreement”) to acquire all of the interests owned by a group of creditors (the "Creditor Group") who own a loan facility pursuant to which various advances were made to Minera Apolo, S.A. de C.V. (“Apolo”) (the “Loan Facility”). The outstanding amount under the Loan Facility is currently approximately USD $2.7 million and the facility was secured against the assets and shares of Apolo located in San Luis Potosi, Mexico. In consideration for the acquisition of the Loan Facility from the Creditor Group, the Company agreed to issue 50 million common shares pro rata to the members of the Creditor Group, pay cash consideration of $0.5 million within 18 months of the closing date of the Agreement, and pay $1.5 million in contingent consideration which is only due upon the completion of certain criteria, including a positive pre-feasibility study at the Pinos Project, the advancement of the project into commercial production, publishing an updated 43-101 with greater than 200,000 ounces of contained gold equivalent ounces for the Pinos Project, or the Company’s owned interest in the Pinos Project falling to less than 51%.

On January 16, 2025, the Company obtained TSX-V approval for the acquisition of the Loan Facility and began the process of enforcing its rights under its security provisions.

On March 7, 2025, the Company entered into an Agreement to Suspend Enforcement Proceedings (the "Non-Enforcement Agreement") dated March 6, 2025, with Candelaria Mining Corporation ("CMC"), who is the 100% owner of Apolo, with respect to the Loan Facility.

Pursuant to the terms of the Non-Enforcement Agreement, CMC will deliver all of the issued and outstanding shares of Apolo to the Company provided that certain conditions set out in the Non-Enforcement Agreement are satisfied, including receipt of all required approvals from the TSX Venture Exchange (“TSXV”). As part of the agreement, the Company agreed to:

On June 30, 2025, the Company obtained 100% ownership of the outstanding shares of Apolo.

Apolo is the 100% owner of the fully permitted gold project located east of the capital Zacatecas in the state of Zacatecas, Mexico (the “Pinos Project”).

On December 31, 2025, the Company entered into a Share Purchase Agreement where it has agreed to sell all the Apolo Shares to a private arm’s length British Columbia company (the “Purchaser”) in consideration of the payment of $5,000 in stages, with $2,450 ($2,445 received as at December 31, 2025) deposit payable on signing which will be refunded if the transaction does not close by February 16, 2026, $550 to be paid on closing and $2,000 to be secured by a promissory note and paid on or before the date that is six (6) months from the closing date. Further, the Purchaser has agreed to assume any and all liabilities of the Company associated with Apolo acquisition, including the assumption of $400 remaining payable on the original purchase agreement in addition to debt in the amount of $1,500 payable to the previous owners of Apolo that will be triggered by the sale of Apolo. The Company concluded that the sale meet the definition of an asset held for sale. During the period ended March 31, 2026, the Company closed the sale of the Pinos Project.

As at December 31, 2025, the impairment of the proposed sale is calculated as follows:

As at December 31, 2025, assets available for sale included:

As at December 31, 2025, liabilities available for sale included:

During the year ended December 31, 2025, the Company commenced an exploration program and identified additional mining areas within its concessions, that the Company is adding to its mine plan.

On December 23, 2025, the Company acquired all of the issued and outstanding Series “A” shares in the fixed capital and all the issued and outstanding Series “B” shares in the variable capital (collectively the “Molimentales Shares”) of Molimentales del Noroeste, S.A. de C.V. (“Molimentales”) through a Concurso Mercantil process (restructuring proceeding equivalent to Chapter 11 in the United States). The Company has received approval from the Second District Court for Commercial Bankruptcy Matters (the “Mexican Court”) to the plan of arrangement (the “Plan of Arrangement”) the Company filed with the Mexican Court under the Concurso Mercantil process.

As part of the acquisition, the Company acquired 60.24% of the debts owed to certain major creditors (the “Major Creditors”) as recognized by the Mexican Court for $8,971 of which of $1,417 remains to be paid. Under the terms of the Plan of Arrangement, the Company has agreed to pay $2,566 in three equal installments in December 2026, 2027 and 2028 to the remaining creditors holding 39.76% of the recognized debt in addition to all outstanding mining concession fees (including penalties and interest), taxes, fees owed to the National Water Commission, supplier debts and certain expenses related to the Concurso proceedings currently estimated at approximately $8,026. Some of the payments described above are facilitated through the Company acquiring the Molimentales Shares by paying the owners of the Molimentales Shares MXN$100 and capitalizing Molimentales with MXN$99,900 for a total of MXN$100,000. The Company determined that the acquisition met the definition of an asset acquisition.

*The Royalty Payable was estimated using a discounted cash flow method. Projected royalty receipts were calculated based on 75 ounces per month and forecast gold prices over the payment period, then discounted to December 23, 2025 at rates of 18.0% to 24.0% to reflect asset-specific risk. This produced a fair value range of $4,100 to $4,470, with a selected value of $4,284. During the period ended March 31, 2026, the Company recorded accretion of $223 on the Royalty Payable which had a balance of $4,507 of which $1,098 is disclosed as current.

During the period ended March 31, 2026, the Company incurred $831 in expenses related to the San Francisco carrying costs.

The fair value allocated to the warrants as at March 31, 2026, was $36,517 (December 31, 2025 - $45,992) and was recorded as a derivative financial liability as these warrants were exercisable in Canadian dollars, differing from the Company’s functional currency.

The fair value of the warrants was calculated using the Black-Scholes Option Pricing Model. Option pricing models require the input of highly speculative assumptions, including the expected future price volatility of a Company’s shares. Changes in these assumptions can materially affect the fair value estimate and, therefore, existing models do not necessarily provide a reliable single measure of the fair value of the Company’s warrants.

On January 26, 2026, the Company announced that it has entered into a definitive arrangement agreement and plan of merger (the “Arrangement Agreement”) with Gold Resource Corporation (NYSE American: GORO) (“GRC”), whereby Goldgroup has agreed to acquire all of the issued and outstanding shares of GRC’s common stock. Pursuant to the arrangement agreement, GRC’s stockholders will receive 1.4476 common shares of the Company for each share of GRC’s common stock adjusted to 0.3619 common shares of Goldgroup for each share of GRC’s common stock as a result of a proposed four-for-one share consolidation to be completed by the Company prior to closing. Since the transaction had not closed as of the financial statement date, the initial accounting for the acquisition is incomplete and certain IFRS 3 disclosures cannot yet be provided. The Arrangement Agreement includes a reciprocal termination fee of $5 million, payable by either party under certain specified termination circumstances. On May 15, 2026, the Company announced an amendment to the Arrangement Agreement. Under the amendment, the parties agreed to replace the previously contemplated four-to-one share consolidation ratio with a consolidation ratio to be jointly determined by the Company and GRC, subject to TSX Venture Exchange approval, prior to the effective date of the transaction. The consolidation is intended to assist the Company in meeting the listing requirements of the NYSE American following completion of the proposed transaction. Upon completion of the transaction, GRC stockholders are expected to own approximately 40% of the combined company on a fully diluted in-the-money basis, with existing Goldgroup shareholders holding the remaining approximately 60%. The Company also announced the anticipated director nominees for the combined company.

Subsequent to March 31, 2026, the Company has issued 5,183,500 common shares as a result of warrant exercises for gross proceeds of approximately $665 (CAD $919).
