Hinterland Discovers 7.5g/t Gold at Hearne Project, Manitoba
Friday, October 12th, 2007
Hinterland Metals Inc. is pleased to announce the results of its 2007 surface prospecting and sampling program on the Hearne project located approximately 120km west of Churchill in Northern Manitoba. The primary goal of the program was to examine visible outcrops on the property for uranium. The work instead uncovered a significant gold discovery as well as unusually rich chromite concentrations.
Anomalous gold values up to a maximum of 7.5g/t were obtained along a 4.5km segment of sulphide-bearing quartzite and quartz-pebble conglomerate outcrops marked by a distinctive green colour. Grab samples returned chrome values up to a maximum of 1.8% and more than 55% of the samples returned greater than 1000ppm Cr. Iron and chrome values show a strong correlation indicating the presence of detrital chromite. The green colour of the outcrops is most likely caused by fuchsite mica derived from the alteration of chromite grains.
It is well documented on Archean cratons elsewhere in the world that fuchsite-bearing quartzites and quartz pebble conglomerates are prospective for paleo-placer deposits of gold and/or uranium. Chromite is commonly found in the heavy mineral suite accompanying gold and/or uranium in alluvial placers. Placer deposits form as a result of the weathering and erosion of bedrock material followed by the concentration of that material at a distance from its source.
