Domeyko Sulfuros Project

The Domeyko Sulfuros Project is an exploration property situated in the Atacama Region of northern Chile. The project encompasses 75 mining concessions, covering an area of 10,056 hectares within the Dos Amigos mining district.

Strategically positioned 53 kilometers south of Vallenar, the property offers exceptional accessibility, located just 60 kilometers from the Pacific coast and less than one kilometer from the Pan-American Highway, and adjacent to the town of Domeyko. This advantageous positioning significantly enhances its logistical potential. Its low-altitude setting, combined with excellent connectivity and access to critical infrastructure such as electrical power, water, and logistical support, provides substantial operational advantages.

From 1997 to 2015, the enrichment blanket at the Dos Amigos target was the focus of open-pit mining operations. During this period, approximately 12 million tonnes of ore, with copper grades exceeding 0.85% (predominantly secondary sulfides), were extracted and processed using heap leaching and solvent extraction-electrowinning (SX/EW) methods at an on-site facility. Currently, the primary objective of the Domeyko Sulfuros project is to evaluate the copper-gold (Cu-Au) porphyry potential, with a focus on delineating primary Cu-Au resources.

In February 2024, Tintina completed a NI 43-101 Independent Technical Report for the Domeyko Sulfuros Project (see news release dated February 15, 2024), providing a comprehensive overview of the technical characteristics of the property.
