Luca Reports Strong Q1 2024 With C$7.3m Of Net Income

VANCOUVER, May 30, 2024 - Luca Mining Corp. ("Luca" or the "Company") (TSXV: LUCA) (OTCQX: LUCMF) (Frankfurt: Z68) is pleased to announce financial results for the three months ended March 31, 2024.

Highlights

• Production of 14,148 troy oz of gold equivalent up 20% from Q4 2023, being comprised of 4,297 ounces of gold, 207,505 ounces of silver, 3,068 tonnes of zinc, 791 tons of copper and 661 tonnes of lead.
• Total Net Revenue of C$22.04 million, an increase 21% from Q4 2023
• A milestone achievement of Positive Operating Earnings: generated C$4.8 million in operating income and C$7.3 million in net income.
• Cash Flow: C$4.04 million in positive operating cash flow before working capital changes.
• Operating Costs: All-in Sustaining costs per AuEq oz produced ("AISC") was US$1,325 at Campo Morado and US$1,690 at Tahuehueto for consolidated AISC of US$1,549. We note that AISC is expected to decrease at Tahuehueto and at Campo Morado as both mines continue to ramp up production in 2H 2024.
• Construction at Tahuehueto nearing completion: The third filter press, being the last major component to complete construction at Tahuehueto is currently being installed with commissioning upon completion of installation and expected to be operational in Q2 2024.
• Campo Morado Improvement Project ("CMIP") moving forward: The two major steps we are focused on going forward are to increase throughput at the Campo Morado mine, which is well underway and to implement the copper lead separation process to produce three separate concentrates (copper, zinc and lead).

Ramon Perez, President stated, "We are very proud to announce our Q1 2024 results. We have achieved a number of significant milestones that are key to our overall growth plans, including increasing revenues, and most importantly generating positive operating cash flow, before working capital changes, and positive net income. We started Q1 with pre-production at Tahuehueto averaging 250 tpd and ended Q1 with an average 450 tpd. We are now expecting to commission Tahuehueto at the end of Q2 at which point we expect to increase production to +800 tpd. At Campo Morado, the Mine Improvement Program we initiated in Q4 2023 has resulted in better recoveries which is reflected in the financial information presented. The Q1 2024 results at Campo Morado are based on an average throughput of approximately 1,390 tpd, and we are currently in the process of ramping up to our next target of 2,000 tpd as we move into June 2024.

It is a great position to be in. We have two long life mines - a producing copper-zinc mine and a brand new gold-silver mine moving to commercial production at a time when metal prices are rising. We expect to continue creating significant shareholder value and take advantage of our unhedged gold, silver and copper production".

Lisa Dea, Chief Financial Officer, commented, "Looking ahead, we anticipate that the positive trajectory observed in Q1 2024 will persist throughout the second quarter and the remainder of the 2024 year. These developments affirm our commitment to driving growth and shareholder value creation."

Qualified Persons

The technical information contained in this News Release has been reviewed and approved by Mr. Chris Richings, Vice-President Technical at Luca Mining as the Qualified Person for the Company as defined in National Instrument 43-101.

Cautionary Note Regarding Production Decisions and Forward-Looking Statements

It should be noted that Luca declared commercial production at Campo Morado prior to completing a feasibility study of mineral reserves demonstrating economic and technical viability. Accordingly, readers should be cautioned that Luca's production decision has been made without a comprehensive feasibility study of established reserves such that there is greater risk and uncertainty as to future economic results from the Campo Morado mine and a higher technical risk of failure than would be the case if a feasibility study were completed and relied upon to make a production decision. Luca has completed a preliminary economic assessment ("PEA") mining study on the Campo Morado mine that provides a conceptual life of mine plan and a preliminary economic analysis based on the previously identified mineral resources (see news releases dated November 8, 2017, and April 4, 2018).

Positive operating cash flow is defined as excluding capital, debt repayment and Trafigura financing.

Statements contained in this news release that are not historical facts are "forward-looking information" or "forward-looking statements" (collectively, "Forward-Looking Information") within the meaning of applicable Canadian securities laws. Forward Looking Information includes, but is not limited to, disclosure regarding the planned program to improve mining operations at Campo Morado; and other possible events, conditions or financial performance that are based on assumptions about future economic conditions and courses of action; the timing and costs of future activities on the Company's properties, such as production rates and increases; success of exploration, development and bulk sample processing activities, and timing for processing at its own mineral processing facility on the Tahuehueto project site. In certain cases, Forward-Looking Information can be identified using words and phrases such as "plans," "expects," "scheduled," "estimates," "forecasts," "intends," "anticipates" or variations of such words and phrases. In preparing the Forward-Looking Information in this news release, the Company has applied several material assumptions, including, but not limited to, that the current exploration, development, environmental and other objectives concerning the Campo Morado Mine and the Tahuehueto Project can be achieved; that the program to improve mining operations at Campo Morado will proceed as planned; the continuity of the price of gold and other metals, economic and political conditions, and operations. Forward-Looking Information involves known and unknown risks, uncertainties and other factors which may cause the actual results, performance, or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the Forward-Looking Information.

NON-IFRS FINANCIAL MEASURES

The Company has disclosed certain non-IFRS financial measures and ratios in this MD&A, as discussed below. These non-IFRS financial measures and non-IFRS ratios are widely reported in the mining industry as benchmarks for performance and are used by Management to monitor and evaluate the Company's operating performance and ability to generate cash. The Company believes that, in addition to financial measures and ratios prepared in accordance with IFRS, certain investors use these non-IFRS financial measures and ratios to evaluate the Company's performance. However, the measures do not have a standardized meaning under IFRS and may not be comparable to similar financial measures disclosed by other companies. Accordingly, non-IFRS financial measures and non-IFRS ratios should not be considered in isolation or as a substitute for measures and ratios of the Company's performance prepared in accordance with IFRS.

Non-IFRS financial measures are defined in National Instrument 52-112 - Non-GAAP and Other Financial Measures Disclosure ("NI 52- 122") as a financial measure disclosed that (a) depicts the historical or expected future financial performance, financial position or cash flow of an entity, (b) with respect to its composition, excludes an amount that is included in, or includes an amount that is excluded from, the composition of the most directly comparable financial measure disclosed in the primary financial statements of the entity, (c) is not disclosed in the financial statements of the entity, and (d) is not a ration, fraction, percentage or similar representation.

A non-IFRS ratio is defined by 52-112 as a financial measure disclosed that (a) is in the form of a ration, fraction, percentage or similar representation, (b) has a non-IFRS financial measure as one or more of its components, and (c) is not disclosed in the financial statements.

Working Capital

Working capital is a non-IFRS measure that is a common measure of liquidity but does not have any standardized meaning. The most directly comparable measure prepared in accordance with IFRS is current assets and net of current liabilities. Working capital is calculated by deducting current liabilities from current assets. Working capital should not be considered in isolation or as a substitute from measures prepared in accordance with IFRS. The measure is intended to assist readers in evaluating our liquidity.

Mine Operating Cash Flow before Taxes

Mine operating cash flow before taxes is a non-IFRS measure that does not have a standardized meaning prescribed by IFRS and therefore may not be comparable to similar measures presented by other issuers. Mine operating cash flow is calculated as revenue minus production costs, transportation and selling costs and inventory changes. Mine operating cash flow is used by management to assess the performance of the mine operations, excluding corporate and exploration activities and is provided to investors as a measure of the Company's operating performance.

EBITDA

EBITDA is a non-IFRS financial measure, which excludes the following from net earnings:

• Income tax expense;
• Finance costs;
• Amortization and depletion.

Adjusted EBITDA excludes the following additional items from EBITDA:

• Share based compensation;
• Non-recurring impairments (reversals);
• Loss (gain) on Settlement of debt;
• Significant other non-routine finance items.

Adjusted EBITDA per share is calculated by dividing Adjusted EBITDA by the basic weighted average number of shares outstanding for the period.

Management believes EBITDA is a valuable indicator of the Company's ability to generate liquidity by producing operating cash flow to fund working capital needs, service debt obligations, and fund capital expenditures. Management uses EBITDA for this purpose. EBITDA is also frequently used by investors and analysts for valuation purposes whereby EBITDA is multiplied by a factor or "EBITDA multiple" based on an observed or inferred relationship between EBITDA and market values to determine the approximate total enterprise value of a Company.

EBITDA is intended to provide additional information to investors and analysts. It does not have any standardized definition under IFRS and should not be considered in isolation or as a substitute for measures of operating performance prepared in accordance with IFRS. EBITDA excludes the impact of cash costs of financing activities and taxes, and the effects of changes in operating working capital balances, and therefore is not necessarily indicative of operating profit or cash flow from operations as determined by IFRS. Other companies may calculate EBITDA and Adjusted EBITDA differently.

Realized Price per Ounce and Realized Price per Tonne

Realized price per ounce or per tonne are based on provisional prices received from the sales of gold, silver, zinc, copper and lead before price adjustments and treatment and refining charges.

Operating Cash Flow before Working Capital Changes

Operating cash flow before working capital changes per share is a non-IFRS measure that does not have a standardized meaning prescribed by IFRS and therefore may not be comparable to similar measures presented by other issuers.Operating cash flow per share is calculated by dividing cash from operating activities by the weighted average shares outstanding.Operating cash flow per share is used by management to assess operating performance on a per share basis, irrespective of working capital changes and is provided to investors as a measure of the Company's operating performance.

Cash Cost per Au/Eq Ounce, All-In Sustaining Cost per Au/Eq Ounce, All-In Cost per Au/Eq Ounce and Production Cost per Tonne

Cash costs per gold equivalent oz and production costs per tonne are measures developed by precious metals companies in an effort to provide a comparable standard; however, there can be no assurance that the Company's reporting of these non-IFRS measures and ratios are similar to those reported by other mining companies. Cash costs per gold equivalent ounce and total production cost per tonne are non-IFRS performance measures used by the Company to manage and evaluate operating performance at its operating mining unit, in conjunction with the related IFRS amounts. They are widely reported in the silver mining industry as a benchmark for performance, but do not have a standardized meaning and are disclosed in addition to IFRS measures. Production costs include mining, milling, and direct overhead at the operation sites. Cash costs include all direct costs plus royalties and special mining duty. Total production costs include all cash costs plus amortization and depletion, changes in amortization and depletion in finished goods inventory and site share-based compensation. Cash costs per gold equivalent ounce is calculated by dividing cash costs and total production costs by the payable gold equivalent ounces produced. Production costs per tonne are calculated by dividing production costs by the number of processed tonnes. The following tables provide a detailed reconciliation of these measures to the Company's direct production costs, as reported in its consolidated financial statements.

All-in Sustaining Costs ("AISC") is a non-IFRS performance measure and was calculated based on guidance provided by the World Gold Council ("WGC"). WGC is not a regulatory industry organization and does not have the authority to develop accounting standards for disclosure requirements. Other mining companies may calculate AISC differently as a result of differences in underlying accounting principles and policies applied, as well as differences in definitions of sustaining capital expenditures. AISC is a more comprehensive measure than cash cost per ounce and is useful for investors and management to assess the Company's operating performance by providing greater visibility, comparability and representation of the total costs associated with producing gold equivalent ounces from its current operations, in conjunction with related IFRS amounts. AISC helps investors to assess costs against peers in the industry and help management assess the performance of its mine.

AISC includes total production costs (IFRS measure) incurred at the Company's mining operation, which forms the basis of the Company's total cash costs. Additionally, the Company includes sustaining capital expenditures, corporate general and administrative expense, operating lease payments and reclamation cost accretion. The Company believes this measure represents the total sustainable costs of producing silver and gold concentrate from current operations and provides additional information of the Company's operational performance and ability to generate cash flows. As the measure seeks to reflect the full cost of gold equivalent ounces from the zinc and lead concentrate production from current operations, new projects capital at current operation is not included. Certain other cash expenditures, including share-based payments, tax payments, dividends and financing costs are also not included.

The following tables provide detailed reconciliations of these measures to cost of sales by quarter and year to date.
