LOS ANDES COPPER ANNOUNCES EXPANSION OF LAND PACKAGE

Los Andes Copper Ltd. has expanded its land package by obtaining first-priority exploration claims over new areas within and adjacent to the current property boundaries for Los Andes' Vizcachitas copper project in Chile.

The claims cover an 18-square-kilometre block within the current property boundary, and another seven-square-kilometre block adjacent to the northeast corner of the property boundary.

The 18 square km block within the current property boundary covers the higher ground bordering the Vizcachitas deposit to the southeast, near the mineralized extensions identified in the 2023 drill program.

Following the ruling made on Feb. 12, 2025, the cancellation of the existing exploitation claims was certified by the Court in Putaendo on March 5, 2025, and recorded in the Putaendo Mine Registration Office on April 1, 2025.

Santiago Montt, chief executive officer of Los Andes, commented: "We are very pleased to have expanded our land package to have first-priority exploration claims over a new combined area of 25 square km. These additional new claims have increased our total land package to 474.4 square km. This new ground has highly prospective geology, providing further potential upside for the Vizcachitas project and the company."
