About Cornerstone Metals Inc.

Cornerstone’s objective is to advance exploration/development stage copper, precious and strategic minerals properties to production in the Americas. The Company’s Management and Board Core Competence is in exploration, permitting, development, construction, and operation of mining projects.

The Company has an option to earn a 100% interest in the Carlin Vanadium Project, which has one of the largest, richest known primary vanadium deposits in North America. The Carlin Vanadium Project is located in Elko County 22km by road (14 miles) from the town of Carlin, Nevada, and is comprised of 72 contiguous unpatented mineral claims totaling 461 hectares (1,140 acres). The Carlin Vanadium deposit was discovered by Union Carbide Corp. (UCC) in the 1960’s, which completed surface mapping, trenching and 152 rotary drill holes in 11,133m (36,525 feet) of drilling. The average drill hole spacing was 60m (200ft) apart within the more densely drilled areas. Drilling indicates a zone of mineralization approximately 55m (180 feet) thick striking north-south over 1,860m (6,100ft) in length and dipping 5°-30° east and west averaging 760m (2,500ft) of down dip extent from surface. The mineralized unit is locally exposed on surface, where it cuts topography, but mostly is found at shallow depths, commonly between 15-60m (50-200 ft) below surface.

Cornerstone also owns 100% (subject to 1.5% NSR) of the West Jerome property, near Jerome, Arizona, on the west side of Freeport McMoRan patented lands. The property, in a Volcanogenic Massive Sulfide camp, is a high-grade, massive sulfide target located 2.4 km south of the past-producing United Verde (32 million tons grading 4.4% copper, 1.5 oz/t silver and 0.04 oz/t gold). The West Jerome property has attractive untested drill targets.
