ATERRA Metals Inc. is focused on the exploration of copper and gold deposits in Chile. Management has been active in Chile since the early 1990s and has made numerous major discoveries over the years including the Volcan Deposit (Andina Minerals), the Fenix Deposit (Atacama Pacific - recently put into production by RIO2) and the Valeriano Deposit (ATEX Resources).
Totora Cu/Au Project
ATERRA recently acquired a group of copper-gold porphyry properties in Chile’s Region III with the goal of outlining a group of near-surface, economically viable copper-gold deposits. Located 60 kilometres south of Vallenar adjacent to Highway 5, the properties include: the Frontera Property which hosts the Frontera copper-gold deposit; the Clinton Property which hosts the Clinton copper-gold porphyry; and the Taruca Property which hosts a number of copper-gold systems including the Totora and Algarrobilla porphyries. A fourth property was recently added to the portfolio – the Sevilla Project. The four properties are collectively referred to as the Totora Cu/Au Project. ATERRA continues to review properties for acquisition in the Totora area.
ATERRA is currently conducting a Phase I drilling program on the Totora Project focusing on infill drilling and identifying extensions of the Totora Cu/Au Porphyry and the Frontera Cu/Au Deposit. The drilling program is scheduled to be completed during the 2nd quarter of 2026. The results of the program will be incorporated into a new mineral resource estimate scheduled for the 2nd half of 2026.
Geological Summary of the Totora Cu/Au Project
The Totora Project area covers a portion of an important NE-SW fault, informally called the "Pajonales Structural Corridor", which hosts a series of mineralized copper-gold porphyries such as Frontera (ATERRA), Pajonales (CMP), Pajonales Norte (CMP), and Clinton (ATERRA).
The Totora Project area lies at the boundary between the Coastal Cordillera to the west, and the Atacama fault system to the east. During the Cretaceous, a thick sequence of andesites and minor sediments developed in an extensional regime within volcanic island-arc settings. A variety of porphyritic stocks have intruded this sequence, some of which are probably contemporaneous with the volcanics. Late Cretaceous porphyritic intrusions host the majority of the copper-gold deposits observed in the area including those within the Totora Project.
