The NX Gold Mine consists of fully integrated underground mining and processing facilities located in southeastern Mato Grosso State, Brazil, approximately 670 kilometers east of the capital city of Cuiabá. It is accessible all-year round by gravel road from the town of Nova Xavantina 18 kilometers to the east, and the site is connected to the national electrical grid. The total NX Gold Mine claim area currently covers approximately 45,300 hectares.

The high-grade, shear-zone hosted, quartz vein system is accessed via a single decline, and current mining operations are focused on the Santo Antonio vein. Ore is processed using a conventional three-stage crushing circuit, milling, and a combination of gravity concentration and intensive leaching and flotation followed by carbon in leach processing. The NX Gold Mine processing facilities have capacity to process approximately 300,000 tonnes of ore per year.

Near mine exploration activities are focused on down-plunge extensions of the Santo Antonio vein, the Matinha vein and untested near-mine targets. Regional exploration targets outside of the mine area have also been identified.
