Nighthawk Reports Gold Recoveries of up to 98.0 percent from the Latest Colomac Metallurgical Test Work

Nighthawk Gold (“Nighthawk” or the “Company”) (TSX: NHK; OTCQX: MIMZF) is pleased to announce results from the second generation of preliminary metallurgical test work on material from the Colomac deposit (“Colomac”), part of the Colomac Gold Project. This second phase of testing focused on the high-grade mineralization and showed exceptional gold recoveries of up to 98.0 percent.

Dr. Michael Byron, President & CEO commented:

“Results from metallurgical testing to-date (both the low-grade and the high-grade material), although preliminary in nature, show the rock at Colomac to be exceptional in terms of grind characteristics, gold recoveries, purity, and responsiveness to all standard gold recovery technologies.

We were particularly encouraged by the preliminary heap leach bottle roll test recoveries on the lower grade rock which showed recoveries of 81.8%. As such we have performed another bottle roll test on the higher-grade material and a more strenuous column percolation test, the results of which will be provided once available.”
