EMA

The EMA Gold Project is located 30 km south of Apui, Brazil with year-round access by gravel roads. The area is located over the mapped Colider group, a Proterozoic volcanic sequence known for gold and base metal deposits.

Location
✔ 30km south with of Apui with year round access by gravel roads;
✔ Covers an area of 18,873.91

Geology and Mineralisation
✔ Initial soil sampling revealed the presence of an extensive gold-in-soil geochemical anomaly associated with a magnetic low within a high magnetic trend;
✔ Gelogical mapping revealed that the magnetic features are related to mafic intrusives (gabbro) emplaced along a regional structural trend;

Trial Mining Licence
✔ Trial mining license granted in 2019. It allows Brazilian Critical Minerals to mine 50,000 tonnes of mineralised rock per annum. The license is renewed annually. Brazilian Critical Minerals has applied for renewal;

Drilling
✔ Brazilian Critical Minerals has drilled a total of 2,246 meters at the Ema Project

Geology

Initial soil sampling at Ema revealed the presence of an extensive gold-in-soil geochemical anomaly associated with a magnetic low within a high magnetic trend (see Fig. 1 below). Geological mapping has revealed that the magnetic features are related to mafic intrusives (gabbro and dolerite) emplaced along a regional structural trend. The low magnetic zones within the mafic bodies may be the result of magnetite destruction by hydrothermal fluids.

Field reconnaissance has revealed the presence of extensive small-scale artisanal workings mainly within felsic volcanics and intrusives (rhyolite and quartz-porphyry) adjacent to the mafic bodies.

Trial Mining License

Brazilian Critical Minerals has been formally granted a trial mining license for Ema, announced in the Amazonas State Government Gazette on June 7, 2019. The trial mining license allows Brazilian Critical Minerals to mine 50,000 tonnes of mineralised rock per annum. The license is renewed annually.Brazilian Critical Minerals has applied for renewal.
