On Sunday, May 4, we reported the completion of an initial mineral resource estimate for the Filo del Sol sulphide deposit, the updated mineral resource estimate for the Filo del Sol oxide deposit, and the updated mineral resource estimate for the Josemaría deposit (collectively referred to as the "Vicuña Mineral Resource"). This new evaluation consolidates the project's position as one of the world's largest copper, gold and silver deposits.

Dave Dicaire, Vicuña's Chief Executive Officer said, "This resource estimate is a major milestone for Vicuña, which significantly advances its vision of developing an integrated project. He added, "With this new and expanded resource base, we are in an optimal position to continue progressing towards the development of a high potential mining district, which is expected to have a substantial impact on local and national populations and economies. Vicuña reaffirms its commitment to work closely with all stakeholders to drive the responsible advancement of this deposit".
