Luca Mining Corp. Expands Gold Mineralization at Santiago Deposit

Luca Mining Corp. recently announced impressive developments at the Santiago Deposit located in Durango, Mexico. As part of their ongoing exploration initiatives, the company has successfully extended high-grade gold mineralization by more than 100 meters to the west, moving towards the producing Perdido vein, which is situated approximately 600 meters away.

These encouraging outcomes are part of Luca's systematic exploration approach. Current drilling efforts are focused on confirming the connection between Santiago and Perdido veins, which may potentially reveal a continuous mineralized structure. While further drilling is necessary to establish this continuity firmly, initial results are highly promising.

Highlighted Findings at Santiago Deposit

The Santiago Deposit has seen its first drilling activity since 2008, marking a significant milestone for Luca Mining. Noteworthy drill results include:

• - DDH25-SGO-008: 2.4 meters of 12.2 g/t gold
• - DDH25-SGO-009: 3.2 meters of 2.17 g/t Au

These results alone contribute to extending the deposit’s strike length by over 100 meters, confirming the robustness of the mineralized structure in this area.

In addition to these high-grade intervals, recent drilling also uncovered the following results:

• - DDH25-SGO-006: 5.7 meters of 6.10 g/t gold
• - DDH25-SGO-007: 6.7 meters of 3.76 g/t gold

Such results not only exceed the modeled grades in the existing resource estimate but also highlight the potential for growth in the company’s gold resources.

The Importance of Santiago Deposit

Located approximately one kilometer from existing mine infrastructure, the Santiago Deposit has never been tapped for mining, making it a prioritized exploration target for the company. This deposit is particularly interesting as it trends onto a recently obtained concession from Fresnillo Plc, setting the stage for extended mineralization exploration.

Underground Drilling Reassures Future Resource Additions

Luca's underground drilling efforts at Tahuehueto are also yielding positive results, indicating the presence of mineralization in every hole drilled thus far. The recent drilling conducted north of the current underground workings has unveiled previously untested, gold-rich breccia zones. For instance:

• - DDH25-236: 5.3 meters of 2.23 g/t AuEq

This result showcases the favorable lateral and vertical continuity within the Creston vein system, reinforcing Luca's agenda to add economically viable resources close to existing mining operations.

Future Exploration Strategies

Luca Mining’s 2025 exploration campaign represents the most significant exploration effort on the property in over a decade. It aims to:

• - Expand existing mineral resources
• - Identify high-grade breccia zones
• - Add immediately mineable material
• - Explore multiple untested vein systems across the concession area

With over 11 kilometers of potential vein structures identified, the company recognizes substantial opportunities for resource expansion beyond the current footprint.

Expert Insights

Paul D. Gray, Vice President of Exploration at Luca Mining, remarked on these developments, stating, “Mineralized veins have been intersected in every drill hole at Santiago this season, with recent results demonstrating the potential to significantly expand the Santiago Deposit. This supports our view that it’s part of a broader mineralized vein system linked to Perdido.”

Summary

The advancements at the Santiago deposit are a key part of Luca Mining Corp.'s ambitious exploration program, which highlights its operational prowess in the mineral-rich landscape of Durango, Mexico. The potential for resource growth is substantial, especially with ongoing drilling campaigns expected to yield further exciting results. Investors and stakeholders will undoubtedly be keeping a close eye on Luca Mining as it continues to unveil the rich potential lying beneath the surface at Santiago and beyond.
