NEWS RELEASE

LUCA COMMENCES EXPLORATION DRILLING AT TAHUEHUETO GOLD MINE

Vancouver, British Columbia, October 23, 2024 - Luca Mining Corp. (“Luca” or the “Company”) (TSX-V:

LUCA; OTCQX: LUCMF; Frankfurt: Z68) is pleased to announce the start of an exploration drilling campaign

at the Tahuehueto gold mine in Durango State, Mexico. The Tahuehueto property comprises a large,

epithermal gold/silver vein system and this campaign is the first significant exploration drill program on

the property in over 10 years. The Company expects the current campaign to include up to 5,000 metres

of diamond core drilling in 26 holes from underground over the next 4-6 months. The drill plan takes

advantage of recently developed areas to potentially extend the resource along the modeled veins.

Dan Barnholden, CEO, commented, “Tahuehueto is a brand new mine which will soon be in commercial

production. There are all the indicators of significant resource expansion potential at this project, and I

am excited that our recently completed financing enables us to not only explore that potential but

expeditiously. We have barely scratched the surface at Tahuehueto, and we are focused on unlocking all

potential value for shareholders. Tahuehueto, and this new drill program, will provide ongoing drill results

and steady material news flow for investors over the coming months and into the new year.”<Listen to

Dan provide details>

Mineralization is open along strike and at depth for most of the modeled resource area and the objective

of the current campaign will be a combination of infill and step-out drilling to determine the vertical and

lateral extent of mineralization as well as to identify mineralized brecciated zones within the epithermal

vein system. Recent mining in L evel 23 encountered higher grade mineralization averaging 3.30 g/t Au

over vein widths up to 20 metres (with values up to 65.04 g/t Au) in ore shoots branching off the main

Creston vein (see news release dated May 29, 2024).

In addition to the four veins that make up the mineralized resource, there are at least 14 additional

prospective veins or splays in the current concession area that show a potential to host low-sulphidation

epithermal mineralization. In some cases, the prospective veins and splays may be extensions or

continuations of the currently defined resource. The Company estimates that there are more than 11 km

of prospective vein structures ( measured along strike ), compared to 4.5 km of mineralized veins that

support current resource models. Figure 1 below shows the relative location of prospective veins (yellow)

and veins modeled for resources and reserves (pink) within the Company’s concession area (white).

Surface mapping has been carried out by Company geologists and outside consultants during different

phases of the project to identify potential areas of epithermal mineralization. The prospective veins have

not yet been systematically sampled or explored a nd there is no guarantee that they host a mineralized

resource.

The technical information contained in this News Release has been reviewed and approved by Mr. Chris

Richings, Vice-President Technical at Luca Mining as the Qualified Person for the Company as defined in

National Instrument 43-101.

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).
