About the Company

Astra Exploration Inc. is a precious metals exploration company based out of Vancouver, BC that is actively building a portfolio of high-quality projects in some of the most important mining jurisdictions in Latin America.

The La Manchuria gold-silver project in Santa Cruz, Argentina, over which Astra has an option to acquire 90% interest from the owner, Patagonia Gold Corp, is a high-grade gold and silver low sulphidation epithermal (LSE) deposit located in the prolific Deseado Massif which hosts multiple world-class LSE precious metals deposits including Cerro Vanguardia and Cerro Negro, Santa Cruz, Argentina.

The 100% owned Pampa Paciencia gold and silver project in northern Chile is located in the Paleocene mineral province in proximity to such major operating mines as Spence and Sierra Gorda. The project shares several important geological similarities to other Paleocene LSE gold-silver deposits including Faride and El Peñón.

The 100% owned Cerro Bayo project in northern Chile is located in the Maricunga belt approximately 20 km from the Refugio Mine. The project hosts a high sulphidation epithermal (HSE) +/- porphyry gold system with similarities to the Salares Norte deposit to the north in the same belt. The Maricunga belt is one of the most endowed regions in the world for gold and copper deposits.
