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 prices for 98% flake V2O5 have steadily risen from under US$3.00/lb less than 3 years ago, to its current price of US$19.30/lb.

About the Company

The Company has an option to earn a 100% interest in the Carlin Vanadium Project, located in Elko County 22 km by road (13 miles) from the town of Carlin, Nevada. The project is comprised of 72 contiguous unpatented mineral claims totaling 461 hectares (1,140 acres). The Carlin Vanadium Project hosts the Carlin Vanadium Deposit which is flat to shallow dipping and at shallow depths, 0-60 m (0-200 ft) below surface. 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).

The Company 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.
