Value Proposition – The Company will find undervalued mining projects that can be explored and then advanced to development and production. The core competence of the management includes advanced stage exploration, permitting, stakeholder agreements, development and construction and operations of underground and open pit mines.
Lone Mountain, New Mexico
The 1530 acre (629 ha.) Lone Mountain property in the Chino-Tyrone Copper District covers a near surface copper oxide deposit underlain by a deeper porphyry copper-skarn deposit. The property lies proximal to and between Freeport McMoRan’s two open pits (Chino and Tyrone) – both with SX- EW plants. Lone Mountain has a Level 4 exploration permit, which allows for up to 176 drill sites with 3 holes per site. This permit, along with environmental bonds in place and recently renegotiated surface landholder agreements makes this project drill-ready.
Historical drilling by past explorers largely targeted the sub vertically oriented copper oxide deposit with vertical holes, however, the shift to angled drilling in 2011 resulted in improvements in grade and size of the deposit. Cornerstone will use angled RC drilling with an aim to quickly justify a sizeable new copper oxide resource.
Mimbres, New Mexico
The 2040 acre (803 ha.) Mimbres project lies 4 kilometres southeast of Freeport McMoRan’s operating Chino open pit copper mine. Mimbres has potential to host a significant copper oxide deposit.
West Jerome, Arizona
The 2579 acre (1020 ha.) West Jerome property lies 2.4 km south of the past producing United Verde Mine, a VMS deposit that produced 33 MT @ 4.36% Cu or 2.9 billion lbs. of copper. Both geological and geophysical indications on West Jerome support the potential of a large buried VMS body. A modest drill program can test that hypothesis.
Twin Peaks, Arizona
This project has copper oxide at surface. Historical drilling shows the potential for a copper oxide deposit at Twin Peaks in an area of excellent infrastructure.
