Luca Mining Corp. reports operating and exploration developments from its Mexican mining portfolio, including the Tahuehueto gold-silver mine in Durango and the Campo Morado polymetallic VMS mine in Guerrero State. Recurring updates cover underground and surface drilling, assay results, mineralized zones near existing workings, and resource-expansion targets tied to gold, silver, copper, lead and zinc mineralization.
Company news also covers production results, cash flow and debt updates, exploration budgets, mine sequencing, and technical work related to Campo Morado mill optimization and expansion. These releases frame Luca as an operating precious- and base-metals miner with active near-mine exploration and processing-improvement initiatives.
Luca Mining (LUCMF) reported mixed third-quarter 2026 production results, with gains at Campo Morado and lower output at Tahuehueto. Campo Morado gold, silver and zinc production and sales rose quarter over quarter as grades and metal recoveries improved; copper declined on lower feed grades. Temporarily reduced access to higher-grade mining areas lowered Tahuehueto grades, production and sales despite modest recovery improvements.
Consolidated production included 5,351 ounces of gold and 334,043 ounces of silver. Cash fell to approximately $19.1 million at September 30 from $24.7 million at June 30. Third-quarter drilling totaled approximately 12,100 metres. Pending acquisitions include Cozamin, with $290 million upfront and up to $95 million in deferred and contingent consideration, and El Barqueño, expected to close in Q4 2026 subject to regulatory approvals and customary closing conditions.
Capstone Copper (LUCMF) agreed to sell its Cozamin copper-silver-zinc-lead mine in Zacatecas, Mexico to Luca Mining for total consideration of up to $385 million.
The consideration comprises $275 million in upfront cash (subject to customary closing adjustments), $15 million in Luca shares issued at closing, $35 million in deferred consideration on the first anniversary of closing, and up to $60 million in contingent cash payments tied to average annual LME copper prices for 2027–2029. Net proceeds are expected to strengthen Capstone’s balance sheet and support its growth pipeline in Chile and the United States. The transaction is expected to close in Q4 2026, subject to customary conditions and regulatory approvals, including stock exchange and Mexican antitrust clearance, and is not subject to shareholder or financing conditions.
Luca Mining (LUCMF) signed a definitive asset purchase agreement on September 17, 2026 to acquire 100% of the El Barqueño gold-silver-copper project in Jalisco, Mexico from a Mexican subsidiary of Agnico Eagle.
The over-32,000-hectare property has road access and hosts a 2025 historical mineral resource estimate of 399,265 ounces gold equivalent indicated at 1.47 g/t AuEq and 650,046 ounces inferred at 1.43 g/t AuEq, which Luca treats as historical and not current and states should not be relied upon. Consideration includes an initial US$10 million in Luca shares at closing, up to US$30 million in drilling and production-linked contingent payments in cash or shares, and up to US$20 million tied to production milestones, plus a 2.0% NSR on certain areas with a buyback right for half at US$12.5 million. Closing is targeted for Q4 2026, subject to Mexican and TSX Venture Exchange approvals and customary conditions.
Luca Mining (LUCMF) reported new 2026 exploration drill results from the Tahuehueto gold-silver mine in Durango, Mexico, including the first surface drilling at the Catorce Zone since 2008.
The key Catorce intercept from hole DDH26-RCE-01 returned 9.9 m of 5.39 g/t AuEq from 199.5 m, including 1.0 m of 27.56 g/t AuEq from 205.4 m. Catorce lies about 250 m from existing underground development and is interpreted as a southern extension of the Creston Vein. At Creston, new underground holes such as DDH26-248 and DDH26-249 delivered intervals including 6.2 m of 6.37 g/t AuEq and 3.4 m of 4.77 g/t AuEq in areas 20–35 m below Level 20, with all 14 drillholes in this new area intersecting the vein.
A Termite underground rig confirmed mineralization at the Perdido Vein with 0.9 m of 7.60 g/t AuEq in TRT26-07, close to planned H2 2026–H1 2027 mining areas. Two contract diamond rigs are on site and a third surface rig is en route, supporting ongoing near-mine resource expansion drilling.
Luca Mining (OTCQX: LUCMF) reported strong Q2 2026 results, with revenue rising 47% year-over-year to $58.4 million and net earnings of $10.5 million ($0.04 per share), versus a $3.2 million loss in Q2 2025. Adjusted EBITDA increased 156% to $14.3 million, despite a $1.9 million negative provisional pricing adjustment on prior concentrate shipments.
For the first half of 2026, Luca generated $116.0 million in revenue, $23.1 million in net earnings and $36.7 million in Adjusted EBITDA. Operating cash flow before working capital was $13.9 million in Q2, funding about $11.3 million of capital investment and yielding $2.6 million of free cash flow before working capital. The company reduced debt, met Empress silver stream obligations, repurchased shares under its NCIB and ended Q2 with $24.7 million in cash. Operationally, Tahuehueto throughput averaged 1,115 tpd, above its 1,000 tpd capacity, while Campo Morado delivered 32.3 million ZnEq pounds, up 6% year-over-year.
Luca Mining (OTCQX: LUCMF) reported new underground and surface drill results from the Campo Morado polymetallic VMS mine in Guerrero State, Mexico. Key highlights include underground hole CMUG-26-50 at Largo Norte intersecting 183.7 m grading 1.18 g/t Au, 72.42 g/t Ag, 0.39% Cu, 0.45% Pb and 1.67% Zn from 3.6 m, with higher‑grade subintervals.
At the unmined Naranjo zone, surface hole CMNJ-26-02 cut 9.6 m of 4.05 g/t Au and 241.09 g/t Ag from 175.3 m, while underground hole CMUG-26-46 returned 90.6 m of 0.99 g/t Au, 40.07 g/t Ag and 0.94% Cu from surface. Additional significant intercepts were reported at Naranjo, El Rey and Estrella de Oro. According to Luca, 13,571 m have been drilled from 60 underground holes and 20,063 m from 75 surface holes in the current campaign, aimed at expanding near‑mine resources, improving production flexibility and potentially extending Campo Morado’s mine life.
Luca Mining (OTCQX: LUCMF) reported Q2 2026 production with consolidated payable output of 5,373 oz gold, 267,404 oz silver, 656k lbs lead, 6,347k lbs zinc and 1,963k lbs copper. Produced metal totaled 6,161 oz gold, 334,237 oz silver, 1,942k lbs lead, 8,879k lbs zinc and 2,660k lbs copper.
As of June 30, 2026, Luca held cash of $24.7 million, down from $36.4 million on March 31, 2026, reflecting underground development, record exploration drilling of about 12,400 metres in Q2 (about 22,000 metres year-to-date), lump-sum tax payments and share repurchases under its NCIB. Revenue was negatively affected by lower gold and silver prices and downward provisional pricing adjustments on prior concentrate shipments.
At Campo Morado, efforts to build a stockpile increased mined tonnes but reduced milled tonnes, temporarily lowering metal production and cash generation. According to Luca, debt has been reduced to approximately $1.4 million, with full repayment expected in July 2026, and both mines continue to undergo optimization and exploration to extend mine life and improve flexibility.
Luca Mining (OTCQX:LUCMF) reported new 2026 drill results from the Tahuehueto gold-silver mine in Durango, Mexico, outlining a new high-grade breccia zone in the Creston vein system.
Highlights include 4.7 m of 6.73 g/t AuEq and multiple other high-grade intercepts near existing underground workings, confirming down-plunge continuity below Level 20 and supporting potential near-mine resource expansion and integration into the near-term mine plan.
Luca Mining (OTCQX: LUCMF) reported new drill results from the Campo Morado mine in Mexico, including 28.4 m at 2.28 g/t gold, 134.89 g/t silver, 0.57% copper, 0.95% lead and 3.69% zinc at the unmined El Rey zone.
Underground holes at the Naranjo zone intersected up to 93.7 m of polymetallic mineralization. Luca has drilled 12,035 m underground and 16,535 m from surface in 2026 and is using VRIFY’s DORA AI software, which has outlined six priority target zones for further evaluation.
Luca Mining (OTCQX: LUCMF) reported operational progress at its Campo Morado and Tahuehueto mines as of May 31, 2026. Key updates include higher stockpiles, steady mill throughput, improved mining and milling rates, new operational leadership, and the departure of two senior technical executives.
