Mining News: Northern Neighbors: Replacement-style gold found at Yellowknife

TerraX Minerals Inc. Oct. 26 reported results from additional channel sampling of replacement-style mineralization in the Hebert-Brent Shear area of its Yellowknife City gold project, Northwest Territories. In August, TerraX reported 11 meters of 7.55 grams-per-metric-ton gold from channel sampling at the Hebert-Brent Zone; followed by six meters of 10.26 g/t gold at the Hebert-Brent South zone and 17.86 meters of 2.21 g/t gold (previously reported as 15.3 meters of 2.23 g/t gold) at the Hebert-Brent East zone. Since September extensive hand excavation and washing was carried out in the Hebert-Brent Shear area to allow more channel sampling and detailed mapping of the mineralized zones. In particular, the original H-B and the H-B East zones were expanded along and across strike. On sample from the original H-B zone returned 17 meters of 1.93 g/t gold. Additionally, excavation was carried out along the North-South trending Brent zone, allowing six channels to be cut across this zone, with particular interest in the area where the Brent zone intersected the northeast trending H-B East zone, were one trench returned four meters of 13.89 g/t gold. TerraX President Joe Campbell said, “The recent work on the Hebert-Brent area has confirmed that gold mineralization resides in multiple surfaces of sulphide replacement at the intersection of north trending mineralizing shears with the contacts between felsic intrusives and their host rocks. Replacement-style deposits, such as Hemlo and Éléonore, can be very large gold producers, and recognition of this deposit type on the YCG property adds a previously unrecognized and important target type to TerraX’s exploration focus.”
