Corvus's Alaskan subsidiary sold the West Pogo project and Goodpaster database to Millrock Resources for US$120,000 in cash, keeping net smelter return royalties, and gave Millrock until September 1, 2015 to option the LMS project (US$775,000 over 5 years, with a retained 3% precious-metals royalty). The company calls these non-core and says the cash will fund exploration at North Bullfrog in Nevada, so it is moving away from the Alaskan assets it reported on in the 2014 LMS technical report. The LMS option is not yet exercised.
Corvus released a preliminary economic assessment (PEA) and updated resource estimate for its North Bullfrog project in Nevada, built around the newly discovered Yellowjacket deposit.
