Vancouver, B.C., April 28, 2025, Luca Mining Corp. (“Luca” or the “ Company”) (TSX-V: LUCA; OTCQX:

LUCMF; Frankfurt: Z68) is pleased to announce that Luca investors , including certain insiders, have

exercised an aggregate of 38.8 million share purchase warrants worth USD$14.0 million ( CAD$19.8

million). The Company has substantially reduced its debt by USD $8.4 million since January 1, 2025 ,

resulting in a current debt balance of USD $8.5 million . Luca’s total cash and cash equivalents balance

(including silver bullion on hand ) is currently US$ 20.6 million and growing, a s strong cash flow from

operations continues and further warrant exercises are expected.

Total Warrants Outstanding

Dan Barnholden, CEO, commented, “With the expiry and exercise of most of the warrants associated

with the recapitalization of the Company in 2023, Luca finds itself in a very strong financial position with

a modest number of dilutable securities remaining. While we have a stated goal of eliminating debt as

quickly as possible, we will also continue to fund high impact capital improvements at both of our mines,

aggressively explore our broader property packages, pursue strategic M&A activity and consider the

potential to return capital to shareholders. The improvement in our financial position over the course of

the past year is nothing short of incredible and we appreciate the ongoing support of our shareholders

as well as the excellent work conducted by our employees and various contractors.”

The number of outstanding warrants has been reduced materially, resulting in the Company being well-

funded, with a strong balance sheet. In addition, Luca expects to generate free cash flow in the range

of USD$30 million to USD$40 million in 2025, resulting in one of the best cash flow yields amongst its

peers. Luca is in a unique position to benefit from the continuing strong commodity demand cycle with

its diversified metal production profile. Along with its strong and growing cash balance, debt elimination

in 2026, and expanding production levels, the Company is set for a year of exceptional performance.

Inclusion in Solactive Index Fund

Additionally, Luca notes that the Company has met the inclusion criteria and has been added to the

Solactive Global Copper Miners Total Return Index, with an inclusion date of May 1, 2025. This index is

tracked by the Global X Copper Miners ETF (COPX). Further information is available on the respective

websites for Solactive and Global X.
