News Release
LUCA MINING CONFIRMS FULL OPERATIONAL CONTINUITY AT
TAHUEHUETO MINE FOLLOWING ENVIRONMENTAL INSPECTION
Vancouver, British Columbia , October 9, 2025 – Luca Mining Corp. (“Luca” or the “Company”)
(TSX-V: LUCA; OTCQX: LUCMF; Frankfurt: Z68) is pleased to confirm that operations at its
Tahuehueto Gold Project, located in Tepehuanes, Durango, continue running normally following
an inspection by Mexico’s environmental authority, PROFEPA (Procuraduría Federal de Protección
al Ambiente).
The inspection, part of Mexico’s standard environmental oversight process, reviewed the
project’s compliance with its Environmental Impact Authorization (MIA) issued by SEMARNAT.
During the site review, PROFEPA requested clarification regarding a small legacy area previously
used for tailings storage, located near the processing plant. This area is inactive and does not
affect ongoing mining or processing operations.
As part of the administrative procedure, PROFEPA placed a temporary closure notice on that
specific inactive area pending submission of updated technical documentation. Luca Mining
expects to develop a remediation plan for this area that will not impact ongoing operations.
“Environmental compliance and transparency are central to Luca Mining’s operations,” said
Ramón Pérez, President of Luca Mining. “The temporary notice applies only to a non-operational
section of 0.3 hectares and does not affect current production. We continue to work
constructively with PROFEPA and SEMARNAT. Responsible mining is fundamental to how we
operate.”
Luca Mining continues to operate normally at both its Tahuehueto and Campo Morado mines,
advancing production, optimization, and sustainability initiatives.

Cautionary Note Regarding Forward-Looking Statements
It should be noted that Luca declared commercial production at Campo Morado prior to
completing a feasibility study of mineral reserves demonstrating economic and technical
viability. Accordingly, readers should be cautioned that Luca’s production decision has been
made without a comprehensive feasibility study of established reserves such that there is
greater risk and uncertainty as to future economic results from the Campo Morado mine and
a higher technical risk of failure than would be the case if a feasibility study were completed
and relied upon to make a production decision. Luca has completed a preliminary economic
assessment (“PEA”) mining study on the Campo Morado mine that provides a conceptual life
of mine plan and a preliminary economic analysis based on the previously identified mineral
resources (see news releases dated November 8, 2017, and April 4, 2018).
