10:12 AM EDT, 08/28/2025 (MT Newswires) -- Luca Mining ( LUCMF ) was edging up early Thursday after saying it has secured a 100% interest in a large mining concession adjacent to the company's Tahuehueto Mine in Durango, Mexico, for US$400,000 cash.

A statement noted the Humaya 3 mining concession, which covers 2,507 hectares and directly surrounds the Tahuehueto Mine, is not subject to any underlying NSR royalties. With this acquisition, Luca expands its land position at Tahuehueto by more than 25%, to 10,000 hectares.

"The Humaya 3 mining concession surrounds the Tahuehueto Mine and with this acquisition we have significantly increased both the size and exploration potential of our mineral tenure at Tahuehueto," said Paul Gray, vice president, exploration. "Known veins hosting our current mineral resources are interpreted geologically to extend along strike both to the northeast and the southwest onto this newly acquired concession. In particular, the Santiago vein, which hosts Mineral Resources and Reserves at the mine and is the focus of our current surface drilling program, extends to the northeast directly onto this ground and represents a high-priority drill target."

Luca Mining ( LUCMF ) shares were up $0.01, to $1.55, on the TSX Venture Exchange.
