LUCA REPORTS RECORD NET QUARTERLY REVENUE IN Q2 2024 OF

US$18.2 MILLION, UP 49% YEAR-OVER-YEAR

Vancouver, British Columbia, August 29, 2024

Luca Mining Corp. (“Luca” or the “Company”) (TSX-V: LUCA; OTCQX: LUCMF; Frankfurt: Z68) is pleased to announce

its financial results for the six months ended June 30, 2024.

Highlights

• Record Net Quarterly Revenue for Q2 2024 of US$18.2 million, up 49% from Q2 2023. Total Net Revenue

for the six months ended June 30, 2024, of US$34.5 million, an increase of 33% over the same 2023 period.

• Positive Net Earnings of US$4.7 million for Q2 2024, an increase of 217% over Q2 2023. Q2 Earnings per

share (“EPS”) increased 130% over the same 2023 period at US$0.03 per share. Total Net Earnings for the six

months ended June 30, 20 24, were US$10.0 million, a 303% increase over the same 2023 period with EPS

increasing 175% to US$0.06.

• Cash flow from Operations: US$739,000 in positive cash flow from operations, with cash flow from operations

before working capital changes at US$3.4 million.

• Positive EBITDA and Adjusted EBITDA : US$6.1 million in positive EBITDA and US$4. 1 million in positive

Adjusted EBITDA for Q2

• Production of 13,947 troy oz of gold equivalent: being comprised of 4,278 ounces of gold, 188,267 ounces

of silver, 3,125 tonnes of zinc, 706 tons of copper and 667 tonnes of lead.

• Operating Costs: All-in Sustaining costs per AuEq oz produced (“AISC”) was US$1,714 at Campo Morado and

US$1,677 at Tahuehueto resulting in a consolidated AISC of US$1,766. AISC increased in Q2 due to a reduction

in tonnes milled over Q1, offset by reduced overall sustaining capital expenditure as Tahuehueto construction

completed. AISC is expected to decrease at both Tahuehueto and at Campo Morado as production ramps up in

the second half of 2024.

• Tahuehueto Construction Completed: The installation of the third filter press in August 2024 marked the

completion of major construction at Tahuehueto. The Company is now commissioning the plant and anticipates

ramping up to full production by Q4 2024.

• Campo Morado Improvement Project (“CMIP”): Progress continues on refurbishment of float cells,

thickeners and filters to ensure reliable plant operation. The focus remains on two key objectives: increasing

mill throughput, and sustaining plant performance. T he copper-lead separation stage of the project is

advancing and is expected to be completed by Q4 2024.

Dan Barnholden, CEO stated, “I am very pleased with our Q2 2024 results. We have achieved positive net income,

positive EBITDA and positive Adjusted EBITDA for the second quarter in a row, as well as positive cash flow from operations.

I fully expect this trend to continue as Campo Morado and Tahuehueto continue to ramp up to full capacity. We have

engaged a leading mine contractor, Cominvi, S.A. de C.V., for our Campo Morado operations which will improve our mobile

equipment availability as well as pro vide enhanced efficiencies going forward. These improvements, along with the

ongoing Campo Morado Improvement Project and Tahuehueto achieving commercial production in the near future, sets

the stage for exciting growth in the second half and substantial cash flows in 2025. ”

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 fea sibility 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

Luca Mining Corp.

Suite 410, 1111 Melville Street

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, s uch 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 t o

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. There can be no assurance that Forward-Looking Information will prove to be accurate, as actual

results and future events could differ materially from those anticipated in such statements. Accordingly, readers should

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.

Luca Mining Corp.

Suite 410, 1111 Melville Street

Vancouver, BC, V6E 3V6, Canada

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 accordanc e 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 deter mined 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. It also excludes income from streaming.

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 sha re is calculated by dividing cash from operating activities by the basic 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 AuEq Ounce, All-In Sustaining Cost per AuEq Ounce, All -In Cost per AuEq 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.
