Notes to the condensed consolidated interim financial statements

(Unaudited - Expressed in thousands of US dollars, unless otherwise indicated)

1. NATURE OF OPERATIONS

Luca Mining Corp. is the parent company of its subsidiary group (collectively, the "Company" or "Luca") and is a publicly traded corporation incorporated in Canada, with its head office located at 410 – 1111 Melville Street, Vancouver, BC, V6E 3V6 and its registered and records office at 2501 – 550 Burrard Street, Vancouver, BC V6C 2B5. Luca's common shares are listed on the TSX Venture Exchange ("TSXV") under the symbol "LUCA", quoted on the OTCQX over-the-counter market in the USA under the symbol "LUCMF" and quoted on the Frankfurt Stock Exchange under the symbol "Z68".

The Company is a producer of base and precious metals and is also engaged in the acquisition, exploration and development of resource properties. The Company is currently producing gold, silver, zinc, copper and lead at the Campo Morado mine and mill ("Campo Morado") located in the state of Guerrero, Mexico and the Tahuehueto mine and mill ("Tahuehueto") located in the state of Durango, Mexico.

2. BASIS OF PREPARATION

These unaudited condensed consolidated interim financial statements ("Interim Financial Statements") have been prepared in accordance with International Accounting Standards ("IAS") 34 - Interim Financial Reporting and do not include all of the information required for a full annual financial statements and should be read in conjunction with the Company's audited consolidated financial statements for the year ended December 31, 2024 (the "Annual Financial Statements").

The preparation of consolidated financial statements requires management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates.

These Interim Financial Statements are presented in United States dollars ("US") and include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation of these subsidiaries.

On May 30, 2024, the Company sold its 99.98% interest in Prestadora de Servicios Arcelia, S.A. de C.V. ("PSA") to a third party in Mexico for $2 ($45 Mexican Pesos) recognizing a gain on the sale of $2,087 in the unaudited condensed consolidated interim statements of (loss) earnings and comprehensive (loss) earnings. This gain represents the difference between the sale price and the carrying amounts of the assets and liabilities that were derecognized at the date of disposition. The results of PSA's operations are reflected in the consolidated financial statements through the date of sale, May 30, 2024.

These Interim Financial Statements were approved by the Company's Board of Directors on November 17, 2025. Certain comparative figures have been reclassified to conform to the current period presentation.

As described in Note 13, during the year ended December 31, 2024, the Company identified that the amendments made to the Stream Agreement on August 13, 2024 resulted in the Amended Streaming Agreement being recognized as a derivative financial liability. The Company's previously-filed interim financial statements as at and for the three and nine months ended September 30, 2024 presented the Amended Streaming Agreement as deferred revenue. As a result, certain comparative information presented herein for the three and nine months ended September 30, 2024 has been restated to reflect the impact of the reclassification of the Amended Streaming Agreement from deferred revenue to a derivative financial liability on August 13, 2024.

The following tables summarize the impact of the restatement on the interim statements of loss for the three and nine months ended September 30, 2024.

For the three months ended September 30, 2024 As previously reported Adjustment As Restated
Fair value of derivative liability in excess of deferred revenue $ - $(14,440) $(14,440)

3. MATERIAL ACCOUNTING POLICIES, ESTIMATES AND JUDGMENTS

The material accounting policies applied in these Interim Financial Statements are the same as those applied in the Company's Annual Financial Statements as at and for the year ended December 31, 2024, which included information necessary or useful to understanding the Company's business and financial statement presentation.

In preparing these Interim Financial Statements, the significant judgements made by management in applying the Company's accounting policies and the key sources of estimation uncertainty were the same as those that were applied to the Annual Financial Statements and should be read in conjunction with the Annual Financial Statements.

The accounting policies presented in Note 3 to the Annual Financial Statements have been applied consistently to all years presented and by all subsidiaries in the group in the preparation of the Interim Financial Statements.

4. AMOUNTS RECEIVABLE

September 30, 2025 December 31, 2024
Trade receivables $ 3,799 $ 770
VAT recoverable 3,318 6,608
Income tax receivable 607 -
Other receivables 1,013 267
$ 8,737 $ 7,645
Less: non-current portion of VAT recoverable 732 8
$ 8,005 $ 7,637

The Company's trade receivables from concentrate sales are expected to be collected in accordance with the terms of the existing contracts with its customer. No amounts were past due as at September 30, 2025.

At the reporting date, the Company assessed the timing of collection of the total VAT receivable of $3,318 (December 31, 2024 – $6,608) and concluded that $732 (December 31, 2024 – $8) of the VAT recoverable is not expected to be collected within the next 12 months, therefore it was classified as non-current other assets.

a) Trafigura (Campo and Tahuehueto)

The Company has had loans outstanding to Trafigura since 2017. As a result of previous non-compliance with the terms and conditions of the Company's loans with Trafigura, on November 12, 2020, the Company agreed to transfer all of its assets in the Campo Morado and Tahuehueto mines into a trust, governed by a trustee and a trust agreement (the "Trust"), in order to secure the full repayment of the outstanding loans.

On January 1, 2024, the Company had two outstanding loans to Trafigura, the Trafigura Campo loan ("Trafi Campo") and the Trafigura Tahuehueto loan ("Trafi Tah") for $1,385 and $12,602 respectively (collectively the "Trafigura Loans"). The Trafi Campo loan bore interest at three-month SOFR plus 5.26% and matured on June 30, 2024, and the Trafi Tah loan bore interest at one-year SOFR plus 6.72% and matured on December 31, 2024.

On January 11, 2024, the Company received an additional loan from Trafigura for $2,500 under the Trafi Campo loan agreement, converted $5,800 of the Trafi Tah loan into a non-interest-bearing convertible debenture (The "Convertible Debenture") and concurrently amended the terms of the Trafigura Loans. The Trafi Campo loan's maturity date was extended to June 30, 2025, with repayments of $260 plus interest commencing on April 30, 2024. The Trafi Tah loan's maturity date was extended to January 3, 2026, with repayments of $200 plus interest commencing on March 31, 2024. After six months, the repayments on the Trafi Tah loan will increase to $345 plus interest.

Trafigura conditionally assigned the Convertible Debenture to its affiliate Urion Holdings ("Malta") Limited ("Urion"), with such assignment to be executed upon Urion being included in the existing security arrangements between the Company and Trafigura (the "Condition"). The Convertible Debenture had originally been signed and placed in escrow, and was released on August 22, 2024 when the Condition was met. The Convertible Debenture was set to mature three years from the date it was released from escrow and made effective but could have been repaid prior to that date upon providing 60 days written notice, provided that the Trafigura Loans and the Breakwater Loan (Note 11(b)) had been repaid in full (the "Early Prepayment Option"). Trafigura could have elected to convert, in whole or in part, the Convertible Debenture principal at any time prior to the maturity date at a conversion price of CAD$0.35 per common share. Any Shares issued under the Convertible Debenture would have been subject to a four month plus one day hold period under applicable Canadian securities laws.

The conversion option in the Convertible Debenture does not meet the fixed-for-fixed criterion under IAS 32 due to the currency mismatch between the US dollar denominated debenture and the Canadian dollar denominated conversion price and functional currency of the Company. This results in a variable conversion outcome driven by exchange rate fluctuations. The Early Prepayment Option also meets the definition of an embedded derivative because its value fluctuates based on interest rates and it is not closely related to the debt host instrument. Consequently, the entire debenture is classified as a financial liability, with the conversion feature and Early Prepayment Option recognized separately as a combined embedded derivative liability, measured at fair value through profit or loss (FVTPL) under IFRS 9. The host debt instrument is classified at amortized cost. The conversion

11. LOANS PAYABLE (continued)

of a portion of the Trafi Tah loan into the Convertible Debenture was accounted for as an extinguishment of the portion of the Trafi Tah loan. The portion of the Trafi Tah loan settled as part of this transaction was derecognized at its carrying amount, and the Convertible Debenture was recognized at its fair value, including the debt host component and the embedded derivatives. The difference between the carrying amount of the Trafi Tah loan that was extinguished, and the fair value of the Convertible Debenture was recognized as a loss of $5,766 in the year ended December 31, 2024.

On August 22, 2024, the Company and Trafigura further amended the outstanding Trafigura Loans to extend the maturities of the Trafi Campo loan to December 2025 and the Trafi Tah loan to July 2026. For Trafi Campo, repayments are to be made in fifteen equal installments commencing in October 2024 at $130 and increasing to $300 in January 2025. For Trafi Tah, repayments are to be made twenty-two installments commencing October 2024 at $200 and increasing to $345 in April 2025. The Company recognized a loss of $40 in the period ended September 30, 2024, through the unaudited condensed consolidated interim statements of (loss) earnings and comprehensive (loss) earnings for the change in fair value due to the amendment to the terms of both loans.

On January 7, 2025, the Company, along with an arm's-length third-party, Jaluca Limited ("Jaluca"), reached an agreement with Urion to repurchase 100% of Luca's $5,800 Convertible Debenture held by Urion. The Company and Jaluca purchased 43% and 57% of the Convertible Debenture, respectively. The total price paid for Luca's portion of the Convertible debenture was $3,099, which was allocated between the debt and the derivative liability in the amounts of $1,572 and $1,527, respectively. Upon closing of the transaction, the Company immediately canceled its portion of the Convertible Debenture and Jaluca converted its purchased share of the Convertible Debenture at the Convertible Debenture's exercise price of $0.35 for a total of 13,566,771 shares, extinguishing the debt. The Company recognized a gain on the debt settlement of $150 in the period ending September 30, 2025, through the unaudited condensed consolidated interim statements of (loss) earnings and comprehensive (loss) earnings.

b) Breakwater Loan Agreement

The Company has a loan outstanding to Breakwater Resources Ltd. ("Breakwater"), a subsidiary of Trafigura Mexico, S.A. de C.V. ("Trafigura") which bears interest at 10% per annum and is repayable in equal monthly installments of $207. On January 11, 2024, the Company and Breakwater amended the terms of the loan agreement to extend the maturity date to June 2025 with repayment to commence in April 2024 with equal monthly principal repayments of $110 plus interest. On August 22, 2024 the Company and Breakwater further extended the maturity date of the loan to December 2025 with repayment to commence in October 2024 with payments initially at $55, increasing to $124 in January 2025.

c) Accendo Loan Facility

The Company had a loan facility agreement with Accendo Banco, S.A., Institución de Banca Multiple ("Accendo") for $12,000 (the "Loan Facility"), of which $6,200 had been drawn down. The Loan Facility was for a four-year term with equal monthly principal repayments commencing after a twelve-month grace period, bore interest at 13.5% per annum, payable quarterly on the drawn amount and was secured by a second ranking security interest over all the assets of the Company.

On September 29, 2021, the Mexican National Banking and Securities Commission revoked Accendo's operating license to organize and operate as a multiple banking institution and commenced a liquidation process to protect the savings of the bank's clients. The Company had a balance of $5,800 available from the Loan Facility for drawdown. However, due to the ongoing liquidation process, the Company's ability to access this remaining balance was impaired.

The Company's Loan Facility was assigned to Latapi Consultores, S.A. de C.V. ("Latapi") by Accendo and on December 6, 2023, the Company and Latapi agreed to settle the outstanding Loan Facility's principal and interest of $7,993 by the Company issuing 17,750,000 common shares of the Company at $0.45 per share to Latapi and Latapi forgiving $2,205 of the Loan Facility. The transaction closed on January 23, 2024, with the issuance of the common shares. As a result of the settlement, the Company recognized a gain of $4,542 in the period ended September 30, 2024, through the unaudited condensed consolidated interim statements of (loss) earnings and comprehensive (loss) earnings.

13. STREAM AGREEMENT (continued)

On April 14, 2021, the Company entered into a silver stream agreement (the "Stream Agreement") with Empress Royalty Corp. ("Empress") in which Luca will deliver to Empress silver credits in an amount equivalent to 100% of the first 1,250,000 ounces of payable silver contained within produced lead and zinc concentrates from the Tahuehueto mine; thereafter, the stream percentage of silver delivery will step down to 20% of the payable silver from produced lead and zinc concentrates. All streaming obligations will fully terminate after 10 years. To accommodate the arrangement, Empress has been accepted into the Trust Agreement. Empress, to secure the Stream Agreement advanced a total of $5,000 with a first initial payment of $2,000 received on April 29, 2021, and the remaining $3,000 advance payment received on July 22, 2021. At inception, the streaming arrangement was determined to be deferred revenue and subject to variable consideration, and it contains a significant financing component. As such, the Company recognizes a financing charge at each reporting period which increases the deferred revenue balance to recognize the significant financing element that is part of the arrangement. In addition to the deposit amount, Luca is also compensated for delivering silver credits at 20% of the silver purchase price, further impacting the overall economics of the transaction.

On August 13, 2024, the Company and Empress amended the streaming agreement whereby, with the completion of the construction at Tahuehueto, the Company will deliver silver under the agreement beginning in July 2024, except the delivery of ounces of refined silver attributable to production for the month of July 2024 will be delivered on the earlier of (i) the completion of the Company's next equity financing or (ii) the date on which refined silver attributable to production for the month of September 2024 is delivered (The "Amended Streaming Agreement"). The Company fulfilled this obligation on September 11, 2024, and delivered 9,098.71 ounces for July production.

Additionally, as part of the Amended Streaming Agreement, on August 16 and August 30, 2024, the Company purchased from third parties 5,454.50 ounces and 10,221.46 ounces of refined silver valued at $150 and $300 respectively and delivered the ounces to Empress, and on September 26, 2024, the Company paid to Empress $150 in cash which was converted to the equivalent of 4,710.32 ounces of refined silver.

As a result of the Amended Streaming Agreement, the Company was required to settle the Stream Agreement other than with the delivery of silver from the Tahuehueto mine; therefore, the Stream Agreement no longer meets the criteria to be accounted for as deferred revenue and has been accounted for as a derivative instrument since August 13, 2024. The fair value was determined using a discounted cash flow model based on the expected future deliveries of silver to Empress, the future silver price and an appropriate discount rate.

| Inputs | September 30
2025 | December 31
2024 |
| --- | --- | --- |
| Silver Spot Price (per ounce) | $ 46.65 | $ 28.91 |
| Discount rate | 16.75% | 20.01% |

Further, the Amended Streaming Agreement provides that, in addition to the regular monthly streaming payments, commencing on October 31, 2024, the Company will deliver a total of 45,085.16 ounces of refined silver over twelve equal monthly installments of 3,757.10 ounces each.

For the three and nine months ended September 30, 2025, the Stream Agreement was remeasured, and the Company recognized losses of $10,067 and $19,094, respectively (September 30, 2024 - $2,274 and $2,274), due to changes in the fair value of the derivative liability recorded in (loss) earnings.

Risk-free interest rate - 2.97%
Expected life of options (years) - 1.5 years
Expected annualized volatility - 87%
Expected dividend yield - Nil

b) Stock Options

The Company has adopted an Omnibus equity compensation plan (the "Plan") under the rules of the TSXV pursuant to which the Company's Board of Directors is authorized, from time to time, to grant a varying range of incentive awards, including stock options, restricted share units ("RSU"), deferred share units ("DSU"), performance share units ("PSU") and other share-based awards (the "Awards") to employees, consultants, directors and officers. The Plan is a rolling Awards plan whereby the number of Awards issuable under the plan shall not exceed, on a rolling basis, 10% of the Company's issued and outstanding common shares at the time of grant.

16. RESERVES (continued)

Under the Plan, the exercise price of each stock option will be determined by the Board but may not be less than the market price of the Company's common shares on the date of grant, subject to any discount permitted under applicable stock exchange rules which, in the case of the TSXV, is currently a maximum of 25%. The stock options can be granted for a maximum term of 10 years with vesting terms determined by the Board of Directors. No individual may be granted options exceeding 5% and no consultant or individual employed to provide "investor relations activities" may be granted options exceeding 2% of the Company's common shares outstanding in any 12-month period.

16. RESERVES (continued)

In determining the fair value of the stock options issued, the Company used the Black-Scholes option pricing model to establish the fair value of options granted during the period by applying the following assumptions:

September 30, 2025 December 31, 2024
Risk-free interest rate 2.69% 3.18%

Expected dividend yield Nil Nil

c) Restricted share units

The Company's Restricted share units ("RSUs") are settled in equity. The fair value is determined based on the quoted market price of the Company's common shares at the date of the grant. The RSUs are recognized as share-based compensation and are expensed over the vesting period with corresponding amount recorded in equity reserves. All the RSUs vest on August 15, 2025.

24. FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

Fair value hierarchy

Financial instruments included in the consolidated statements of financial position are measured either at fair value or amortized cost. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

The fair value hierarchy establishes three levels to classify the inputs to valuation techniques used to measure fair value:

  • Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.
  • Level 2 inputs are quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, inputs other than quoted prices that are observable for the asset or liability (for example, interest rate and yield curves observable at commonly quoted intervals, forward pricing curves used to value currency and commodity contracts and volatility measurements used to value option contracts), or inputs that are derived principally from or corroborated by observable market data or other means.
  • Level 3 inputs are unobservable (supported by little or no market activity). The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs.

The table below summarizes the valuation methods used to determine the fair value of each financial instrument:

Financial asset or liability Methods and assumptions used to estimate fair value
Trade receivables Trade receivables arising from the sales of metal concentrates are subject to provisional pricing, and the final selling price is adjusted at the end of a quotational period. These are marked to market at each reporting date based on the forward price corresponding to the expected settlement date.
Derivative Liability The fair value of the derivative liability arising from a convertible debenture used to cancel debt, is measured using a partial differential equation approach.
Stream Agreement The fair value of the Stream Agreement is determined based on a discounted cash flow model using the assumptions outlined in Note 13.

The carrying value of cash and cash equivalents, other receivables, other assets, amounts payable and accrued liabilities and loans payable, all of which are carried at amortized cost, approximate their fair value given their short-term nature. Trade receivables and related derivatives and derivative liability arising from the convertible debenture are classified within Level 2 of the fair value hierarchy. The fair value of the Stream Agreement is classified with level 3 of the fair value hierarchy.
