Centenario Gold Corp. Initiates Exploration Program at Los Reyes Copper-Gold Project in Mexico

Centenario Gold Corp. has commenced the first phase of work at the Los Reyes copper and gold exploration project in Chihuahua, Mexico, initiating detailed mapping and sampling of historic underground mine workings that date back to the early 1900s and have never been systematically sampled. This initial program focuses on a north-south trending contact zone extending one kilometer, with subsequent plans for a 1,500-meter diamond drilling program designed to test extensions of a high-grade copper-zinc-silver skarn zone previously mined by ASARCO, a historic U.S. mining company. The company expects to receive necessary permits by late April 2026, with drilling to follow immediately.

The Los Reyes property is located approximately 170 kilometers south-southeast of Chihuahua city and covers an area of historical mining activity along the western contact of a large granodiorite intrusive body. Historical mining dates to the early 1700s, with ASARCO extracting approximately 200,000 tons of high-grade copper-zinc-silver material from the Jibosa mine workings in the late 1800s. More recent exploration by Valterra Resource Corporation in 2019 along an 800-meter strike identified a copper-gold skarn zone over 100 meters wide with strongly copper-enriched mineralization. Surface sampling from that program averaged 3.1% copper, with 22 of 28 samples exceeding 1% copper, and anomalous samples contained elevated precious and base metal values including up to 0.57 g/t gold, 25.3 g/t silver, 0.47% molybdenum, and 1.7% zinc.

The implications of this exploration program are significant for understanding the full potential of the Los Reyes project, as systematic modern exploration could confirm the continuity and depth extensions of mineralization that has shown historical high-grade results. The project's location in a historically productive mining region, combined with previous sampling results indicating substantial copper grades, suggests potential for economic mineralization that could contribute to Mexico's mining sector. The drilling program specifically targets depth extensions beyond 100 meters, which could substantially increase the known mineralized zone and provide critical data for resource estimation.

This work represents an important step in advancing the Los Reyes project toward potential development, with the initial mapping and sampling providing essential geological context for the planned drilling. The project's historical significance, demonstrated by early 20th century mining and ASARCO's operations, combined with modern exploration techniques, creates opportunity for discovering substantial mineral resources. The company's progress through permitting and planned drilling activities will be closely watched by industry observers interested in copper and gold exploration in Mexico, particularly given growing global demand for these metals.
