Notes to the Interim Condensed Consolidated Financial Statements (unaudited)

(All amounts expressed in U.S. Dollars, unless otherwise indicated)

On June 23, 2025, the Company exercised its option to acquire the mining concession contract under the option agreement entered into on June 24, 2020 (the “First Guayabales Option”). As a result, the Company and the optionor executed an addendum to the original agreement pertaining to the First Guayabales Option. Consequently, the Company has expedited the timeline for obtaining full ownership of the mining concession contract and no longer has the option to terminate the agreement (See Note 7(a)(i)).

In accordance with the Company’s accounting policy under IFRS 6, the total consideration owing to the optionor under the amended agreement has been reflected as a mining concession contract with a corresponding financial liability (for the unpaid portion) (See Note 12).

As at June 30, 2026, the remaining fair value of the long-term liability outstanding for this agreement is $nil (December 31, 2025 - $1,425,561). (See Note 12).

As part of the acquisition of the mining concession contract, the Company has estimated a provision for environmental remediation of $1,857,509 (See Note 9). This provision relates primarily to the treatment and closure of two small tailings ponds, a waste dump, and sealing and backfilling of historical mining tunnels. The obligation arises from past activities conducted in the concession area prior to the Company’s acquisition (See Note 7(a)(i)).

The Company expects to undertake a progressive remediation program beginning in 2026 and continuing through 2033, with the objective of completing the environmental remediation works required under applicable regulations.

The provision for environmental remediation has been measured at present value using a discount rate of 9.50% over the expected remediation period from 2026 to 2033, resulting in an initial recognised provision of $1,589,371.

In accordance with IAS 37 Provisions, Contingent Liabilities, and Contingent Assets, the provision represents the estimated present obligation for remediation. Consistent with IAS 16, Property, Plant and Equipment, the related cost has been capitalised as part of the acquisition cost of the mining concession, as it is directly attributable to the acquisition of the mining concession contract.

On March 27, 2026, the Company entered into an irrevocable agreement to acquire rights derived from a mining concession application related to the Trap target at the Guayabales Project for total consideration of $3,482,718, payable in three equal instalments through 2028. The present value of the total consideration was determined to be $3,185,535 using a discount rate of 9.50% for the period 2026–2028 (See Note 12 (d)).

Completion of the assignment is contingent upon the granting of the mining title by the National Mining Agency (“ANM”) to the current applicants and the subsequent registration of the assignment in favor of the Company.

In accordance with the Company’s accounting policy under IFRS 6, the total consideration owing to the seller under the amended agreement has been reflected as a mining concession contract with a corresponding financial liability (See Note 12).

As at June 30, 2026, the remaining fair value of the long-term liability outstanding for this agreement is $2,076,633.

(All amounts expressed in U.S. Dollars, unless otherwise indicated)

On July 16, 2025, the Company signed an agreement to acquire a mining concession for a total consideration of $750,000. The present value of the total consideration is determined to be $703,401 using a discount rate of 9.25% for the period 2025–2027.

In accordance with the Company’s accounting policy under IFRS 6, the total consideration owing to the seller under the amended agreement has been reflected as a mining concession contract with a corresponding financial liability (for the unpaid portion).

As at June 30, 2026, the remaining fair value of the long-term liability outstanding for this agreement is $356,955 (See Note 12).

Equipment and other fixed assets consist of the following:

During 2025, the Company completed land acquisitions within the Guayabales Project area. These acquisitions consolidated ownership of strategically located properties to support the future infrastructure and operational development of the Apollo discovery.

(All amounts expressed in U.S. Dollars, unless otherwise indicated)

During 2026, the Company continued to acquire strategic land parcels within the Guayabales and San Antonio Project areas to support its exploration activities and potential future project infrastructure and development. Certain land acquisitions have fixed purchase prices payable in instalments over multiple years, resulting in the recognition of financial liabilities for the unpaid consideration. The long-term liabilities arising from these arrangements are further described in Note 12(c). Land additions during the period include the following:

Guayabales Project

San Antonio Project

Right of use assets as at June 30, 2026 comprise one vehicle lease agreement for multiple vehicles with an initial term of three years, two warehouse leases (one with an initial term of three years and another with a total extended term of fifty-six months) and two administrative office leases (one with an initial term of 2 years, renewable for additional 1-year terms, and a second corporate office lease with an initial term of sixty-three months). The value of additions is determined as the present value of lease payments at the inception of the lease (See Note 11).

Lease modifications, net

During the period ended March 31, 2026, the Company modified certain lease agreements, resulting in the remeasurement of lease liabilities with corresponding adjustments to ROU assets in accordance with IFRS 16.

Effective January 1, 2026, the Company modified its warehouse lease by extending the lease term from 36 months to 56 months and increasing the leased area. As a result, the ROU asset was remeasured and the carrying amount increased from $46,709 to $365,435.

The Company also modified its vehicle lease by increasing the fleet and as a result the ROU asset was remeasured and increased from $702,104 to $1,762,332.

The Guayabales Project consists of mining titles, exploration applications, mining concession option agreements and a number of surface rights option agreements. The Guayabales Project is located in the Middle Cauca belt in the Department of Caldas, Colombia.

The Company has entered into four option agreements (the “First Guayabales Option”, the “Second Guayabales Option”, the “Third Guayabales Option” and the “Fourth Guayabales Option”) with third parties to explore, develop and acquire exploration property within the Guayabales Project.

On June 23, 2025, the Company accelerated the terms of the First Guayabales Option agreement, resulting in the transfer of 100% of the mining concession to the Company. The formal transfer was completed on December 30, 2025, at which time the mining concession was formally transferred and registered in the Company’s name with the Colombian National Mining Agency (Agencia Nacional de Minería, “ANM”). In January 2026, the Company made the final payment in lieu of the net smelter return (NSR), and as a result the First Guayabales Option has been fully executed.

In September 2025, the Company secured two additional option agreements (the “Third Guayabales Option” and the “Fourth Guayabales Option”) with third parties to explore and acquire mining concessions.

In October 2023 and May 2024, the Company secured option agreements to purchase surface rights.

First Guayabales Option – Executed Agreement

On June 24, 2020, the Company entered into the First Guayabales Option to acquire a 100% interest in the property.

On June 23, 2025, the Company exercised the option and entered into an addendum with the optionor to accelerate the remaining consideration. The total consideration remained unchanged from the original agreement.

During the year ended December 31, 2025 and in January 2026, the Company accelerated and fully settled all remaining payments under the agreement. Accordingly, as at January 26, 2026, there are no outstanding obligations related to the First Guayabales Option.

In connection with the acquisition of the mining concession contract, the Company recognised a provision for environmental remediation of $1,589,371 (see Note 9), primarily related to legacy site rehabilitation obligations. In accordance with IFRS 6, these costs were capitalised as part of the mining concession asset, resulting in a total recognised asset of $10,918,302 (see Note 5).

Long-term receivable represents value added taxes in respect of exploration activities that will be recovered when the related project commences production, subject to local regulations.

As part of the acquisition of the mining concession asset (See Note 5), the Company recognised a provision for environmental remediation. This amount primarily covers the treatment and closure of two small tailings ponds, a waste dump, and the sealing and backfilling of historical mining tunnels arising from activities conducted prior to the Company’s acquisition (see Note 7(a)(i)). Management has assessed the necessity to undertake the required remediation works to comply with regulatory and operational requirements.

The Company expects to undertake a progressive remediation program from 2026 through 2033 in order to complete the required environmental remediation works under applicable regulations. The provision has been measured at present value using a discount rate of 9.50% over the expected remediation period. In accordance with IFRS 6, these costs were capitalised as directly attributable to the acquisition.

The provision for environmental remediation reflects management’s best estimate based on information available as of the reporting date. The ultimate remediation costs may differ from the amounts recorded due to uncertainties inherent in site conditions, the results of further technical assessments, changes in remediation strategies, regulatory requirements, and other factors not yet fully known. Management intends to continue conducting site investigations and technical evaluations to refine the cost estimate and will adjust the provision as additional information becomes available.

The following represents warrants denominated in Canadian dollars and classified as derivative financial liabilities:

Subscription Warrants – March 2024 Offering

On March 4, 2024, the Company closed a strategic investment by a single purchaser on a non-brokered private placement (the “March 2024 Offering”) of C$18,900,000 ($13,925,729). The March 2024 Offering consisted of the sale of 4,500,000 Units at a price of C$4.20 per Unit.

Each Unit was comprised of one common share in the capital of the Company (“Common Share”) and one-half of one common share purchase warrant (each whole common share purchase warrant, a “Warrant”). Each Warrant entitles the holder thereof to acquire one Common Share, subject to standard anti-dilution provisions, at a price of C$5.01 until March 4, 2027, however the Company has the right to accelerate the expiry of the Subscription Warrants in the event that the Company’s closing price on the TSXV remains equal to or higher than $6.00 for 20 consecutive trading days following the date that is 24 months after the Closing Date, the Company may accelerate the Warrant Term to the date which is 30 trading days following the date a notice is provided to holders of Warrants and a press release is issued by the Company announcing the accelerated Warrant Term. 

The Warrants were classified as derivative financial liabilities as they were denominated in Canadian dollars and the Company’s functional currency is the US dollar. Proceeds from the March 2024 Offering were allocated between Common Shares and Subscription Warrants based on the residual fair value method within the unit.

The issue date fair value of the Warrants was determined to be C$0.72 per warrant with the resulting allocation of the total proceeds for the March 2024 Offering being:

For the year ended December 31, 2025, the Company recognised a derivative loss of $10,564,475, in the consolidated statement of operations and comprehensive loss for the revaluation of the Warrants.

(All amounts expressed in U.S. Dollars, unless otherwise indicated)

Fair value for the Subscription Warrants was determined using the Binomial pricing model using the following weighted average assumptions as at March 20, 2025:

On March 20, 2025, all 2,250,000 Warrants – March 2024 Offering were exercised with total proceeds received of $7,857,044 (C$11,272,500).

During the period ended March 31, 2026, the Company modified certain lease agreements, which resulted in the remeasurement of lease liabilities in accordance with IFRS 16. The remeasurement reflects changes in lease terms, including an extension of lease duration and an increase in the scope of leased assets (See Note 6 (b)).

These modifications did not result in new lease arrangements but rather represent changes to existing contracts. Accordingly, lease liabilities were adjusted to reflect the revised lease payments, discounted at the applicable incremental borrowing rates at the date of modification. The corresponding adjustments were recognised against right-of-use assets.

The lease liabilities were measured on inception of the lease at the present value of the lease payments over the lease term, discounted using a weighted average discount rate of 20.52%, based on the Company’s incremental borrowing rate.

Interest accretion expense or amortization of the discount on the lease liability is charged to the interim condensed consolidated statement of operations and comprehensive loss using the effective interest method.

For the three months and six months ended June 30, 2026, the Company made lease payments of $162,400 and $325,890, respectively (three and six months ended June 30, 2025 – $231,887 and $281,844, respectively) for contracts with terms of 12 months or less and which were recognised as lease expense within exploration and evaluation expenses.

On June 23, 2025, the Company recognised a financial liability as a result of the exercise of its option to acquire the mining concession contract under the First Guayabales Option.

The present value of the total consideration owing to the optionor under the terms of the amended First Guayabales option agreement of $9,833,334 has been adjusted to reflect the time value of money using a discount rate of 9.25% over a period from 2025 to 2027 resulting in the recognition of a mining concession contract of $9,328,931 and a corresponding financial liability (See Note 7 (a)).

The final balance of $1,500,000 was paid on January 26, 2026. Upon completion of these payments, the total outstanding obligation under the agreement was fully settled.

On July 16, 2025, the Company recognised a financial liability as a result of the acquisition of a mining concession under a two-year term for a total consideration of $750,000.

The present value of the total consideration owing to the seller under the terms of the agreement of $750,000 has been adjusted to reflect the time value of money using a discount rate of 9.25% over a period from 2025 to 2027 resulting in the recognition of a mining concession of $703,401 and a corresponding financial liability (See Note 5 (d))

Fair value measurement

Fair market value represents the amount that would be exchanged in an arm’s length transaction between willing parties and is best evidenced by a quoted market price, if one exists.

Fair value measurement is determined based on the fair value hierarchy as follows:

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2: Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices); and

Level 3: Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs).

The carrying values for financial assets and liabilities for cash and cash equivalents, accounts payable and accrued liabilities, lease liabilities and other long-term liabilities approximate their fair values as at June 30, 2026.

Other financial liabilities of $40,857,548 as at June 30, 2026 (December 31, 2025 – $6,510,620) were as follows:

There were no transfers between the fair value hierarchy during the six months ended June 30, 2026.

The Company’s activities expose it to a variety of financial risks, which include currency risk, credit risk, liquidity risk and interest rate risk.

Risk management is carried out by the Company’s management with guidance from and policies approved by the Board of Directors.

Financial Risk Factors

Foreign currency risk

Foreign currency risk arises from future commercial transactions and recognised assets and liabilities denominated in currency that is not the entity’s functional currency. The Company’s functional currency is the U.S. dollar. The Company conducts some of its operating, financing and investing activities in currencies other than the U.S. dollar. The Company is therefore subject to gains and losses due to fluctuations in these currencies relative to the U.S. dollar. The Company does not use derivative instruments to hedge exposure to foreign exchange risk.

As at June 30, 2026, the exchange rates were COP:US$3,443.59, based on Banco de la Republica – Colombia, and CAD:US$0.7037, based on Bank of Canada, respectively (June 30, 2025, COP:US$4,069.67 and CAD:US$0.7330, respectively).

For the six months ended June 30, 2026, the average was COP:US$3,655.50 and CAD:US$0.7257, respectively (six months ended June 30, 2025, COP:US$4,196.15 and CAD:US$0.7095, respectively).

The Company had the following foreign currency balances:

The Company is exposed to foreign currency risk on fluctuations on the balances that are denominated in Canadian dollars and Colombian pesos. As at June 30, 2026, had both the Canadian dollar and the Colombian peso strengthened/weakened by 10% against U.S. dollar with all other variables held constant, the Company would have reported an increase/reduction in the net loss for the six months ended June 30, 2026, of $109,087 and $133,328 (December 31, 2025 - $29,870 and $36,507), respectively.

Credit risk

Credit risk is the risk of loss associated with a counter party’s inability to fulfil its payment obligations. The Company’s credit risk is primarily attributable to cash and cash equivalents and receivables. The Company has no significant concentration of credit risk arising from its properties. The majority of the Company’s cash and cash equivalents are held with banks in Canada and Colombia. Funds held in banks in Colombia are limited to yearly forecasted Colombian denominated expenses. The Company limits material counterparty credit risk on these assets by dealing with financial institutions with credit ratings of at least “BBB-” or higher, or those which have been otherwise approved. Receivables mainly consist of receivables for refundable commodity taxes in Canada and Colombia. Management believes that the credit risk concentration with respect to remaining amounts receivable is minimal.

Liquidity risk

Liquidity risk is the risk that the Company will not have sufficient cash resources to meet its financial obligations as they come due. The Company regularly evaluates its cash position to ensure preservation and security of capital as well as maintenance of liquidity. The Company manages its liquidity risk by proactively mitigating exposure through cash management, including forecasting its liquidity requirements with available funds and anticipated investing and financing activities.

As at June 30, 2026, the cash balance was $93,726,809 (December 2025 – $129,647,421). However, the cash balance is not sufficient to continue to explore, build a mine, and meet all of its future obligations in respect of the option contracts in Note 21 if the Company elects to exercise all its options in respect of all the contracts. Thus, continued operations of the Company are dependent on its ability to develop a sufficient financing plan, receive continued financial support from existing shareholders and/or new shareholders or through other arrangements, complete sufficient public equity financing, or generate profitable operations in the future.

Interest rate risk

Interest rate risk is the impact that changes in interest rates could have on the Company’s earnings and liabilities. The Company’s cash balances are not subject to significant interest rate risk as balances are current.

The Company manages its capital to maintain its ability to continue as a going concern in order to pursue the exploration and evaluation of its mineral interests. The Company mainly relies on equity issuances to raise new capital. The capital structure of the Company includes the components of equity as well as cash and cash equivalents.

The Company prepares annual estimates of exploration and administrative expenditures and monitors actual expenditures compared to estimates to ensure that there is sufficient capital on hand to meet ongoing obligations. The Company maintains its cash in highly liquid short-term deposits which can be liquidated immediately without interest or penalty.

The Company’s overall strategy with respect to capital risk management has remained consistent for the period ended June 30, 2026.

Authorized share capital consists of an unlimited number of common shares without par value. All issued shares are fully paid. No dividends have been paid or declared by the Company since inception.

During the six months ended June 30, 2026 and 2025, the Company issued shares resulting from the following transactions:

Basic earnings (loss) per share are calculated by dividing net income (loss) attributable to equity holders of the Company by the weighted average number of common shares outstanding as follows:

The Company incurred a net loss for each of the periods of six months ended June 30, 2026 and 2025; therefore, all outstanding stock options and share warrants have been excluded from the calculation of diluted loss per share since the effect would be anti-dilutive.

The Company adopted a stock option plan (the “Plan”) pursuant to the Securities Act of Ontario (the “Act”). The aggregate maximum number of shares reserved for issuance under the Plan and all other security-based compensation arrangements (together “Share Compensation Arrangements”) at any given time is 10% of the Company’s issued and outstanding shares as at the date of the grant of the Share Compensation Arrangement. Any shares subject to a stock option under the Plan which have been exercised, cancelled, repurchased, expired or terminated in accordance with the Plan will again be available under the Plan.

Under the Plan, the Company may grant to directors, officers, employees, and consultants stock options to purchase common shares of the Company. Stock options granted under the Plan will be for a term not to exceed 10 years.

The continuity of stock options during the period were as follows:
