About the Venus Copper Project

The Venus Copper Project, which is 100% owned by Altan Nevada, is located within the Yerington copper porphyry district in the Walker Lane mineralized belt in Nevada. It is approximately six miles east-southeast of the Yerington township, and easily accessible by both paved and dirt roads. Altan Nevada's decision to advance exploration at the Venus Copper Project coincides with the recommencement of development at Nevada Copper Corp.'s (TSX: NCU) ('Nevada Copper') Pumpkin Hollow Copper Mine immediately to the north and less than one mile from the tenement boundary.

Pumpkin Hollow, 100%-owned by Nevada Copper, is a fully permitted project, encompassing both underground and open cut mines, and is expected to produce an average 50 million pounds of copper annually over 23 years commencing mid-2019. Located on-strike from Pumpkin Hollow, Altan Nevada's Venus Copper Project now consists of 208 unpatented mining claims covering approximately 4,169 acres (16.9 km2), all situated on Bureau of Land Management (Federal) land.
