On March 10, 2019, Barrick entered into an implementation agreement with Newmont to create a joint venture, named Nevada Gold Mines.
On July 1, 2019, Phoenix was contributed to Nevada Gold Mines, a joint venture between Barrick and Newmont.
Barrick is the operator of the joint venture and owns 61.5%, with Newmont owning the remaining 38.5% of the joint venture.

Summary:
Phoenix is a skarn-hosted polymetallic massive sulfide replacement deposit.
Au-Cu-Ag-Pb-Zn skarn mineralization at Phoenix is centered about the Eocene Copper Canyon granodiorite porphyry stock. Paleozoic sedimentary rocks within two miles of the stock have undergone strong thermal metamorphism (hornfels) and metasomatism (skarn). Metal zonation is manifest by a CuMo core close to the stock grading outward into proximal Cu-Au-Ag, Au-Ag and distal Pb-Zn-Ag mineralization.
The Phoenix Project site lies within the Basin and Range physiographic province and is composed of two relatively flat valleys and steep-sided ranges with approximately 3,700 feet of relief. Elevations range from approximately 4,520 feet along the Reese River to 8,232 feet at Antler Peak. The mountains serve as hydrologic divides that separate drainage basins. The mountain flanks are deeply incised in places, and the resulting canyons collect and discharge runoff to creeks and alluvial fans. The valley floors grade toward the Reese River and Buffalo Valley Playa.
Quaternary alluvial deposits cover most of the valley floors and lower drainage basins. In general, the alluvium fan away from the mountain fronts, with the coarsest material having accumulated in upper alluvial fan deposits and the finest material being deposited in the center of the valleys away from the mountain front. The valley fill in many basin and range valleys in Nevada can be more than 3,000 feet thick.
