Apiacas

Historic production of over 1Moz of placer gold

Overview

The Apiacás Project spans 82,000 hectares in Brazil’s Alta Floresta Belt, with historic production of over 1Moz of placer gold—90% from the Mutum target. Drilling confirms disseminated gold mineralization over a 4km x 1km area, with results including 30.5m @ 0.52 g/t and 62m @ 0.32 g/t gold. Trenching includes highlights of 9m @ 9.4 g/t gold.
Drill results to date do not yet explain the very significant amount of placer gold previously recovered at Mutum. There is a broad spatial relationship between areas of hydrothermal alteration hosting gold mineralization and magnetic lows.
Strong geophysical potential and under-explored primary gold sources make Apiacás a high-upside investment opportunity. Planned drone magnetometer surveys aim to further delineate these trends and to define further drill targets.

Apiacas

Unlocking a New Era of Gold Discovery in Northern Brazil

The Apiacas Project is one of Brazil’s most promising underexplored gold opportunities. Located in the heart of the Alta Floresta Belt, it boasts a legacy of ~1 million ounces of historic placer gold production and compelling drill results across multiple targets. With widespread mineralization, high-grade veins, and bulk-tonnage potential, Apiacas is positioned as a key asset in Altamira Gold’s growth strategy—supported by strong infrastructure, community engagement, and a commitment to sustainable development.

Unlocking Value at Apiacas – Brazil’s Largest Historic Placer Gold Camp

Altamira Gold is advancing the Apiacas Project, a highly prospective gold asset located in the heart of Brazil’s renowned Alta Floresta Belt. With a history of major artisanal production and promising drill results, Apiacas offers scale, untapped discovery potential, and a clear path toward bulk-tonnage development.
