Latest Metallurgical Test Results Exceed 95% Vanadium Extraction from Cornerstone Metals Inc.'s Carlin Vanadium Project
Vancouver, British Columbia--(Newsfile Corp. - June 20, 2018) - Cornerstone Metals Inc.(TSXV: CCC) (OTCQB: CCCCF) (FSE: 1PY)("Cornerstone" or the "Company") is pleased to announce additional preliminary results of metallurgical test work being conducted on its Carlin Vanadium Project in Nevada. The third round of testing has achieved vanadium extraction levels of 95.5%.
"Our testing has very quickly moved the needle from the low 80's, which were strong, to outstanding numbers, far exceeding even our metallurgists' expectations," said Cornerstone President and Chief Executive Officer, Paul Cowley. "These numbers show a clear sign of a major technical breakthrough for our project."
Test work continues on a sample composite generated from an 18.9 metre drill core intercept from the Company's recent diamond drilling verification program on the deposit. The latest results employed a roast/leach/pressure oxidation approach. Ongoing test work will continue to optimize various parameters with the aim of developing a conceptual flowsheet. Once a conceptual flowsheet has been defined, tests will be run across the deposit on a full range of samples. The tests to date have been conducted to demonstrate potential recoveries. At this stage, there is no suggestion that these tests demonstrate economic viability.
Metallurgical test work continues at Sherritt Technologies in Fort Saskatchewan, Alberta, the leader in the development and commercialization of pressure hydrometallurgical processes. Sherritt is a one-stop shop that has a proven track record of developing projects from concept-to-operation with a skilled and experienced team, including process and equipment specialists.
The Carlin Vanadium deposit is considered one of the largest, highest grade primary vanadium deposits in North America (USGS Professional Paper 1802 Critical Mineral Resources of the United States—Economic and Environmental Geology and Prospects for Future Supply dated December 18, 2017).
Vanadium's Growing Importance for Steel Manufacturing and the Energy Sector
Vanadium is growing in importance for key industrial manufacturing sectors, most notably steel and renewable energy. Today, more than 85 percent of the world's vanadium is used in steel manufacturing applications. Its importance to the energy sector is also growing rapidly with more than 10 percent of vanadium production used in energy storage where its substantial cost and performance benefits make it an alternative choice to lithium ion in several areas. Vanadium pentoxide flake prices have risen over the last 2.5 years from under US$3/lb to US$15.7/lb today.
