The NX Gold Mining Complex is located in southeastern Mato Grosso State, Brazil, approximately 670 km east of the capital city of Cuiabá. Doré bars containing gold and silver, as well as lesser amounts of lead, are shipped from the mine weekly by airplane via a gravel airstrip located on the property.

Mineral Reserve & Resource Notes:
1. Effective date of August 31, 2018.
2. Presented mineral resources inclusive of mineral reserves. All figures have been rounded to the relative accuracy of the estimates. Summed amounts may not add due to rounding.
3. Mineral resource gold cut-off grade of 1.40 gpt gold. Mineral resources have been estimated using ordinary kriging inside 10m by 10m by 2m block sizes (with sub-blocks of 2.5m by 2.5m by 0.5m). The mineral resource estimates were prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards for Mineral Resources and Mineral Reserves, adopted by the CIM Council on May 10, 2014 (the "CIM Standards"), and the CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines, adopted by CIM Council on November 23, 2003 (the "CIM Guidelines"), using geostatistical and/or classical methods, plus economic and mining parameters appropriate to the deposit.
4. Mineral reserve estimates were prepared in accordance with the CIM Standards and the CIM Guidelines, using geostatistical and/or classical methods, plus economic and mining parameters appropriate for the deposit. Mineral reserves are based on a long-term gold price of US$1,250 per ounce ("oz"), and a USD:BRL foreign exchange rate of 3.20. Mineral Reserves are the economic portion of the Indicated Mineral Resources. Mineral Reserve estimates include mining dilution at 5% grading 0.5g/t Au and 7% grading 0.5g/t Au for the Brás and Buracão Veins, respectively. Practical mining shapes (wireframes) were designed using geological wireframes / mineral resource block models as a guide.
