November 28, 2017 - Vancouver, British Columbia – Cornerstone Metals Inc. (TSX-V – CCC) (“Cornerstone” or the “Company”) is pleased to announce that the Company is initiating field preparations for its diamond drill program on the Carlin Vanadium Project. Company geologists have designed a drill plan of 1,900m of diamond drilling in 23 holes to verify the grade and zone thicknesses of the historic resource already established from the 1960’s Union Carbide drilling of the vanadium deposit and to provide samples for metallurgical testwork. The Company submitted its Notice of Intent (NOI) application for the drill program to the Bureau of Land Management (“BLM”) November 7, 2017 and is awaiting approval, normally a 45 day process. In anticipation of this approval, crews are going to the Carlin Vanadium property this week to initiate the logistical set-up for the planned diamond drill program. The Company has requested quotes from several drill contractors for the program and will be meeting contractors on site. Company crews will also mark the drill collars in the field as well as the pre-existing roads and for 350m of new road building to access drill sites.

The Carlin Vanadium Project has one of the largest known primary vanadium deposits in the U.S.A. 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 50-200 ft below surface.
