The Robertson property is located in one of the most highly mineralized areas of ground in Nevada, approximately 100 km southwest of Elko, Nevada within the Battle Mountain-Eureka Gold Trend. The property lies at the north end of the Cortez District. Robertson is owned by Nevada Gold Mines (NGM), a joint venture between Barrick Gold Corp. (61.5%) and Newmont Corporation (38.5%). The property is located less than 10 km east of the Pipeline/Cortez Mine Complex, a well-known mining district that hosts NGM gold production from the operating Pipeline and Cortez mines. Mineralization at Robertson occurs as fine-grain particulate free gold hosted in contact-metamorphosed sedimentary rocks and intrusive rocks.
As of December 31, 2022, Robertson’s Proven and Probable Reserves are 1.6 Moz contained in 110 Mt at 0.46 g/t within Measured and Indicated Resources of 160 Mt at 0.42 g/t for 2.2 Moz gold (inclusive resources, 100% basis, cut-off grade not disclosed).
The ongoing Feasibility Study is targeted for completion in 2024 with production targeted for 2027. Production is anticipated from two open pits that will feed NGM’s nearby Cortez Mill Complex with mainly oxide gold mineralization.
The project is being qualified by NGM as an emerging “Tier Two” gold asset which NGM defines as having reserve potential to deliver a minimum 10-year life, annual production of at least 250,000 ounces of gold and total cash costs per ounce of gold over the mine life that are in the lower half of the industry cost curve.
