Santa Helena

High grade gold and copper potential.

Overview

Santa Helena spans 17,587ha in the Juruena Belt, 60km SW of the Jaca porphyry discovery, with excellent highway access (BR-163). Surface sampling has returned up to 172 g/t gold and 0.96% copper, with multiple targets showing high-grade gold values (Gabriel, Flecha Dourada, Dorival, Tucura).

A 1.5km diameter copper-in-soil anomaly with a coincident magnetic anomaly and evidence of stockwork veining in trenches suggest a large-scale hydrothermal alteration system with porphyry potential.

With its combination of high-grade gold, strong copper potential, and underexplored large-scale anomalies, Santa Helena stands out as an exciting investment opportunity in Brazil’s emerging gold-copper frontier. Ongoing assessments and upcoming drill programs could unlock substantial value, positioning Santa Helena as a key asset in the Alta Floresta/Juruena Belt.

Technical Report Corporate Presentation

Santa Helena

Exploring the Future of Gold and Copper in South America.

Our flagship Cajueiro Project holds a 700,000+ oz NI 43-101 gold resource, with expansion potential. Santa Helenaoffers high-gradcopper, while Apiacas is a key gold exploration target. Three additional projects support small-scale production for near-term value. With a proven team, strong infrastructure, and sustainable practices, Altamira Gold is unlocking Brazil’s next major gold and copper discoveries.

Advancing a New Porphyry Copper-Gold Frontier in Brazil

Santa Helena is a high-potential copper-gold project located in the prolific Alta Floresta Belt. With strong trenching results, widespread alteration, and large-scale geophysical anomalies, it offers clear potential for a significant porphyry discovery near infrastructure.
