The Alta Floresta Gold Province

The Alta Floresta gold province is located in the South of the Amazon Craton, in the state of Mato Grosso. It is an established gold producing jurisdiction with an estimated 300,000 kg of placer gold recovered historically mainly by artisanal miners.

Alta Floresta Mining Overview

The Alta Floresta gold province is considered the most desirable gold exploration district in Brazil with large scale historical production from over 40 known deposits.

The area consists of primarily pluto-volcanic sequences generated in a continental arc setting during the Paleoproterozoic.

Between 1980-2000 the province produced approximately 160 tons of gold from alluvial and high grade primary deposits.

Mining activities in Brazil are primarily regulated by the Mining Code of 1967 and the Mining Code Regulation of 1968, which were updated in 2018 to attract more foreign investment and better address environmental concerns.

Exploration and mining activities require the authorization and/or concession of the Federal Government of Brazil, with gold mining being regulated by the federal National Mining Agency (ANM) under the Ministry of Mines and Energy.
