Summary:
North Deposit
The North Deposit of mineralization is located 1,500 ft north of the South Deposit and is centered on a subhorizontal, pipe-like, copper- rich, magnetite-poor skarn and skarn breccia body hosted by hornfels of the Gardnerville Formation (Northwest Deposit). The higher grade mineralization in the skarn breccia grades into a zone of lower copper grade mineralization hosted by granodiorite endoskarn and marble (North Deposit).
The combined Deposit has a 3,500 ft strike length, with true widths of 200 to 900 ft, and a down-dip extent of 1,500 ft and remains open in several directions. Retrograde alteration and sulfide deposition in the North Deposit was focused along fractures at angles to bedding and overprints earlier prograde alteration. Retrograde alteration and mineralization along fractures diminishes away from the breccia core. Chalcopyrite tends to be the last sulfide phase deposited.
South Deposit
The South Deposit, the first discovery on the Property, is a skarn-IOCG magnetite-chalcopyrite body closely associated with an intrusive contact of granodiorite into limestones of the Mason Valley Formation. The deposit is roughly tabular, measuring 3,600 ft along strike, 1,800 ft down- dip, trends northeast, and dips steeply to the northwest. The mineralized section, as defined by USS, can be divided into two zones: a footwall or proximal zone consisting of a 400 to over 1,000 ft thick relatively high grade magnetite with low ........

Summary:
The Open Pit Project is currently designed as a 37,000 stpd operation, expanding in Phase II to a 70,000 stpd operation, The Open Pit Project has two mining areas, the North Pit and the South Pit.
Open pit mining will commence mining with the North Pit, which possesses higher grade followed by the lower grade, South Pit. Four phases were designed for the North Pit and two phases were designed for the South Pit. Ore from the pits will be hauled to a primary crusher, or to the stockpile, located to the west of the pits. Waste will be hauled to the waste rock storage facility (WRSF), which was designed to accommodate waste from both the North Pit and South Pit. Once the North Pit is exhausted, South Pit waste is used to backfill the North Pit.
