LUCA MINING CORP. REPORTS $10.5 MILLION OF NET EARNINGS IN Q2

Q2 Revenue Increases to 58.4 Million; First-Half Net Earnings Reach 23.1 Million

VANCOUVER, BC, Aug. 17, 2026 /PRNewswire/ -- Luca Mining Corp. ("Luca" or the "Company") (TSX-V: LUCA) (OTCQX: LUCMF) (Frankfurt: Z68) is pleased to report operational and financial results for the second quarter and six months ended June 30, 2026. The Company delivered another strong financial quarter, generating revenue of $58.4 million, net earnings of $10.5 million, adjusted net earnings of $6.9 million and Adjusted EBITDA of $14.3 million. Revenue increased 47% and mine operating earnings increased 90% compared to Q2 2025, supported by significantly stronger realized metal prices and continued contributions from both operations.

For the first six months of 2026, Luca generated $116.0 million of revenue, $23.1 million of net earnings and $36.7 million of Adjusted EBITDA. Strong operating cash generation enabled the Company to fund significant underground development, sustaining capital, infrastructure and exploration expenditures, substantially reduce debt, meet its obligations under the Empress silver stream, repurchase shares under its Normal Course Issuer Bid ("NCIB"), and maintain a cash balance of $24.7 million at June 30, 2026.

Q2 2026 Highlights

• Strong and consistent quarterly revenue: Revenue increased 47% to $58.4 million compared with $39.7 million in Q2 2025 and remained above the $57.6 million generated in Q1 2026. First-half revenue reached $116.0 million, an increase of 43% over the comparable period of 2025. Q2 revenue included $1.9 million of negative provisional pricing adjustments related to concentrate shipments made in prior periods.

• Strong profitability continued in Q2: Net earnings were $10.5 million, or $0.04 per share, compared with a net loss of $3.2 million in Q2 2025. Together with the $12.6 million earned in Q1 2026, Luca generated $23.1 million of net earnings in the first six months of 2026, compared with $1.3 million in the first half of 2025. Adjusted EBITDA increased 156% year-over-year to $14.3 million for Q2 and for the first six months of 2026, Adjusted EBITDA reached $36.7 million.

• Positive free cash flow while continuing significant investment: Operating cash flow before working capital changes was $13.9 million during Q2 2026. After approximately $11.3 million of capital investment, the Company generated free cash flow before working capital changes of $2.6 million, compared with negative $3.2 million in Q2 2025. The quarter's capital investment included continued spending on underground development, infrastructure and record levels of exploration activity.

• Tahuehueto exceeded expected throughput: Tonnes milled increased 13% from Q1 2026 and 23% year-over-year, with the operation averaging 1,115 tonnes milled per operating day, exceeding its 1,000 tpd installed plant capacity. Tonnes mined increased 28%, silver production increased 39%, copper production increased 47% and overall AuEq production increased 10% compared with Q2 2025.

• Advanced Campo Morado optimization strategy: Campo Morado produced 32.3 million ZnEq pounds, an increase of 6% compared with Q2 2025. Mining continued to outpace processing as the Company intentionally built ore stockpiles to increase near-term feed blending flexibility while advancing long-term metallurgical optimization initiatives.

• Continued investment in future production flexibility: Sustaining capital expenditures totaled $8.5 million during Q2 and $16.6 million during the first six months of 2026. Investment remained focused on underground development, mine infrastructure, tailings management, processing improvements and operational reliability.

Production and financial performance in Q2 2026 continued to reflect the Company's strategy of investing operating cash flow into underground development, mine preparation, infrastructure and exploration to strengthen the operating platform at both mines. Consolidated tonnes mined increased 6% and tonnes milled increased 3% compared with Q2 2025, while silver production increased 19% and copper production increased 3%.

Dan Barnholden, Chief Executive Officer, commented: "The second quarter reflects another period of significant investment as we continued to strengthen both operations. During the first half, we invested more than $21 million into underground development, infrastructure and exploration, including our highest quarterly exploration drilling activity in at least a decade. These investments are focused on improving operating performance, increasing production flexibility and advancing the significant growth opportunities across our properties.

Operationally, Tahuehueto continues to perform strongly, with mill throughput exceeding budgeted capacity during the quarter, while at Campo Morado we built a stockpile to advance metallurgical optimization initiatives designed to improve near-term recoveries ahead of the Campo Morado Expansion. At both operations, we remain focused on converting these investments into improved operational performance and long-term cash flow generation.

At the same time, we have made significant progress strengthening the balance sheet. We have substantially reduced our debt while continuing to meet our obligations under the Empress silver stream and advance toward its stepdown threshold. With these financial obligations increasingly behind us, we expect a greater proportion of future operating cash flow to be available to support our operations, growth initiatives and shareholders."

Operational Performance

Consolidated tonnes mined increased 6% to 267,028 tonnes during Q2 2026 over Q2 2025 and tonnes milled increased 3% to 260,461 tonnes. Consolidated silver production increased 19% to 334,237 ounces, while copper production increased 3% to 2.7 million pounds. Gold production decreased 7% to 6,161 ounces, zinc production decreased 26% to 8.9 million pounds and lead production decreased 12% to 1.9 million pounds.

Campo Morado (Guerrero, Mexico)

Campo Morado produced 32.3 million pounds of ZnEq during Q2 2026, an increase of 6% compared with 30.4 million pounds in Q2 2025. Tonnes mined totaled 174,497 while tonnes milled totaled 171,237, as mining intentionally outpaced processing to build ore stockpiles and improve future feed blending and operating flexibility.

Precious metal grades improved significantly during the quarter, with gold grades increasing 42% and silver grades increasing 45% compared with Q2 2025. Silver production increased 13% to 234,896 ounces. Metallurgical recoveries, however, remained below prior-year levels as the operation processed ore from multiple mining areas while advancing feed blending and metallurgical optimization initiatives.

The Company continued implementing reagent optimization, flotation circuit improvements and feed blending controls while advancing rehabilitation and optimization of flotation circuits, pumping systems, tailings infrastructure and other critical plant assets. Underground development remained focused on the Naranjo, Largo Norte, Fish and Southwest areas.

Cash cost per ZnEq payable pound sold was $1.02/lb compared with $0.91/lb in Q2 2025. AISC was $1.33/lb, compared with $1.29/lb in Q2 2025, reflecting increased mining and development activity, higher treatment charges and continued investment in sustaining capital. ZnEq payable pounds sold increased 7% during the quarter.

Exploration activity remained significant, with approximately 9,000 metres of diamond drilling completed at Campo Morado during Q2, including underground, surface and geotechnical drilling. The program continues to target near-mine resource additions and the broader district-scale exploration potential of the property.

Tahuehueto (Durango, Mexico)

Tahuehueto continued to strengthen its operating performance during Q2 2026 over Q2 2025. Tonnes mined increased 28% to 92,531 tonnes and tonnes milled increased 23% to 89,224 tonnes. Average throughput reached 1,115 tonnes milled per operating day, exceeding the plant's 1,000 tpd installed capacity.

Higher throughput and stronger silver and base-metal grades supported improved production across several metals. Silver production increased 39% to 99,340 ounces, zinc production increased 16% to 1.6 million pounds and copper production increased 47% to 434 thousand pounds. Overall AuEq production increased 10% to 7,397 ounces.

Gold production decreased 8% to 4,461 ounces as lower gold grades and metallurgical recoveries offset higher throughput. The operation continued advancing underground development into additional mining areas while implementing flotation optimization, reagent adjustments and feed blending controls to improve metallurgical stability.

The transition of underground mining activities to contractor La Cantera continued to support increased mining and processing activity, with additional infrastructure investments in power distribution, compressed air, ventilation, pumping and underground preparation intended to improve production flexibility and operational continuity.

Cash cost was $3,011 per AuEq ounce sold and AISC was $3,538 per AuEq ounce sold, reflecting the increased operating scale, underground development and mine preparation activity, lower gold grades and recoveries, and continued investment in mine and processing infrastructure. Sustaining capital totaled $2.5 million during the quarter.

The Company remains focused on converting the investments made across both operations into improved metallurgical recoveries, production consistency and operational efficiency for sustainable long-term free cash flow generation.
