    Among the largest undeveloped VMS deposits in the prolific Iberian Pyrite Belt

Proyecto Masa Valverde

Proyecto Masa Valverde (“PMV”) consists of several undeveloped volcanogenic massive sulphide (“VMS”) type deposits and targets that are strategically located approximately 28 km from Proyecto Riotinto.

Atalaya acquired a 100% interest in PMV in October 2020, after conducting a period of due diligence and exploration on the property under an earlier option agreement.

PMV is made up of three investigation permits that total approximately 45km 2 and are located along the prolific southern domain of the world-class Iberian Pyrite Belt.

The region benefits from well-developed and modern infrastructure and a long mining history, hosting many world-class mines and deposits.

The project includes the Masa Valverde deposit, the Majadales discovery and the Campanario-Descamisada target. The Masa Valverde deposit is one of the largest single undeveloped VMS systems in the world. The Majadales deposit was discovered by Atalaya and is smaller in scale, but also shallower and higher grade. The Campanario Trend is a 5 km long parallel mineralised corridor, located 1 km north of Masa Valverde and Majadales.

PMV has the potential to be developed as a satellite deposit, whereby material could be mined via underground methods, trucked to Proyecto Riotinto via existing public highway and processed at Proyecto Riotinto’s existing 15 Mtpa plant.
