Luca Reports robust Q1 production results and materially strengthens balance sheet

Luca Mining Corp. (“Luca” or the “Company”) (TSX-V: LUCA; OTCQX: LUCMF; Frankfurt: Z68) is pleased to report production results for the three months ended March 31, 2026, alongside continued strengthening of its balance sheet.

As at March 31, 2026, Luca’s cash position increased to approximately $36.4 million, compared to $25.5 million at year-end 2025. The increase was primarily driven by strong operating cash flow, supplemented by approximately $2.1 million in proceeds from warrant and option exercises and net realized gains of approximately $3.6 million from silver call options. These options were implemented to re-establish exposure to silver prices in light of the silver stream at Tahuehueto.

As previously disclosed in the Company’s Q4/25 financial results, debt has been reduced to approximately $1.4 million, with the remaining balance expected to be fully repaid by mid-2026.

Exploration Update

During the first quarter of 2026, the Company completed approximately 10,058 metres of drilling. Exploration activities were primarily focused on near-mine and resource expansion targets, achieving the objectives of extending mine life and improving production flexibility at the Company’s operating assets.

CEO Commentary

“We started 2026 on strong footing, with solid operating performance and strong silver production in a favorable price environment,” said Dan Barnholden, Chief Executive Officer. “We remain focused on operational improvements at both mines, with particular emphasis on Campo Morado as we advance the Campo Morado Expansion study toward a technical report in the second half of 2026.”

“With a significantly strengthened balance sheet, Luca is well positioned to continue executing on its growth strategy, including advancing exploration, operational optimization, and broader corporate initiatives.”

Non-GAAP Financial Measures

Management believes that the reported non-GAAP financial measures will enable certain investors to better evaluate the Company’s performance, liquidity, and ability to generate cash flow. These measures do not have any standardized definition under IFRS and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Other companies may calculate these measures differently.
