Luca's Cash Balance Surges To Us$21 Million Through Warrant Exercise And Cash Flow

VANCOUVER, 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, as strong cash flow from operations continues and further warrant exercises are expected.

Outstanding warrants have been reduced to the following with the total outstanding common shares of the Company at 253.7 million:

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.

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.
