Nighthawk Gold Corp.

TORONTO, ONTARIO--(Marketwired - April 19, 2017) - Nighthawk Gold Corp. ("Nighthawk") (TSX VENTURE:NHK) is pleased to announce encouraging preliminary results from its ongoing metallurgical test work program on the Colomac Gold project. Testing was completed at Bureau Veritas in Richmond, BC, and audited by Starkey & Associates Inc. in Oakville, Ontario. Three drill core bulk samples from various portions of the Colomac gold deposit were assayed and tested for grindability using the SAGDesign methodology. A master composite was then amalgamated from the bulk samples and used for additional metallurgical testing. Initial results indicate that gold recoveries of up to 96.5% may be achieved and the rock is amenable to all standard gold recovery technologies. This represents a significant increase in recovery over the historic production results of 88.1% (1994 to 1997). Additional testwork is expected to yield further optimization and confirmation of these results.
