Nighthawk Gold Corp (CVE:NHK) has posted encouraging preliminary results from ongoing metallurgical test work at the Colomac gold project in the Northwest Territories, which indicate gold recoveries of up to 96.5% may be possible.
The findings come from three drill core bulk samples from the property.
This represents a significant increase in recovery compared to historic production results of 88.1%, which were seen between 1994 and 1997, the group added.
Further testwork is expected to yield further optimisation and confirm these results.
"Results from this initial metallurgical testing have significantly exceeded our expectations in comparison to Colomac’s known historical recoveries”, said Nighthawk chief executive Dr Michael Byron.
“In particular, Colomac material shows excellent grind characteristics, exceptional gold recoveries and responsiveness to all standard gold recovery technologies, comparing favourably to similar projects in North America.
"It’s also important to note that the rock is exceptionally clean as no deleterious materials were detected that could otherwise adversely affect processing, or impact the environment.
"We are very pleased with the initial results, and expect the final testwork to confirm these findings”.
Nighthawk is a Canadian-based explorer focused on acquiring and developing gold mineral properties in the Northwest Territories.
