The 18km² 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 February 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, CEO 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 25km². These additional new claims have increased our total land package to 474.4km². This new ground has highly prospective geology, providing further potential upside for the Vizcachitas project and the Company."
