Luca Commences Exploration Drilling at Tahuehueto Gold Mine

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 explore that potential.  We have barely scratched the surface at Tahuehueto. Tahuehueto, and this new drill program, will provide ongoing drill results and steady news flow for investors over the coming months.”

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 Level 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 and 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).

Luca Provides Update on Campo Morado Performance and Commencement of Stage 3 of Improvement Project

Luca Mining Corp. (“Luca” or the “Company”) (TSX-V: LUCA; OTCQX: LUCMF; Frankfurt: Z68) is pleased to announce the successful implementation of the first two stages of the Campo Morado Improvement Project (CMIP) and commencement of Stage 3.

In Q4 2023 the Company partnered with Ausenco México S. de R.L. de C.V. (“Ausenco”) to implement a staged improvement project designed to increase metallurgical performance, mill throughput, sustaining plant performance and operating cash flow. The initial phase of the project (Stage 1) included a comprehensive geometallurgical program focused on sampling, training and procedures as well as optimizing the process controls in the plant. The primary goal of Stage 2 was sustainable operations and improving plant reliability. Stage 3 will now build on the improvements to date and implement a new flow sheet with modest modifications to the plant with the goal of producing three high-quality, saleable concentrates of copper, lead and zinc.

The CMIP has already delivered significant financial benefits to the Campo Morado operation with only minor changes to the process plant. These benefits have mostly come from higher copper recovery which has improved by 53% over the same period in 2023. Copper recovery to the bulk concentrate year-to-date (YTD)1 is 68.5% compared to 44.7% during the same period in 2023. Figure 1 below shows bulk concentrate copper grade and Figure 2 shows copper recovery over the last 21 months. This has resulted in an estimated 10% increase of revenue per milled tonne2 over the same period year-on-year assuming constant metals prices.

Figure 1 – Campo Morado Bulk Concentrate Grade

Figure 2 – Campo Morado Copper Recovery to Bulk Concentrate

Work has begun on Stage 3 of the CMIP project which consists of modest but important modifications to the processing plant, including:

  • Revised metallurgical sampling systems.
  • Modernization of reagent dosing systems.
  • New flotation cell air flow monitoring and control.
  • Installation of next generation pH/ORP probes.
  • New bulk rougher concentrate surge tank.
  • Modifications to the bulk regrind circuit to operate with 2-stage regrinding.

Completion of Stage 3 will increase the degree of liberation of the copper and lead minerals, allowing for collection in two separate concentrates through a sequential flotation process. In conjunction with the refurbishment of equipment and a new mine-to-mill strategy, it is anticipated that the CMIP will deliver more robust revenues for the Campo Morado operation. The Company expects to test the copper-lead separation process by the end of the year, with full project completion by Q2 2025.

The Company, together with Ausenco, has demonstrated that the Campo Morado mine and mill are capable of sustained profitable operations and future work will continue to enhance the value of the asset.

CEO Dan Barnholden commented, “The improvements at Campo Morado have been an outstanding success to date and moving to Stage 3 of this program demonstrates Luca’s commitment to ongoing improvement at our assets.

We intend to produce three clean, fully saleable and higher value concentrates of copper, zinc, and lead, which will have an immediate, positive impact on revenues and, ultimately, cash flow.”

  1. YTD includes preliminary production data up to and including September 2024.
  2. It is noted that this calculation is approximate given that total revenue received in any given period is based on several factors including but not limited to head grade, recovery and prices of multiple, marketable metals over time.
