Assay results from rock chip samples from the Blue Creek and Emery Creek targets included gold values up to 1.75 grams per tonne of gold (g/t) and 105 grams of silver. Blue Creek is currently host to 163,000 ounces of the yellow metal at a grade of 0.51 g/t.
Alan Roberts, Otis’s vice president of exploration, said the latest work extended and built upon the mineralization observed in past drilling in a third area, Matrix Creek.
“The surface geochemistry from the Emery Creek target shows potential for subsurface mineralization,” he added.
Roberts told investors that gold and silver found within altered Palaeozoic sediments pointed to surface areas for follow-up.
Planning for 2019
The latest data will feed into the development of a significant drill program to test these detachment structures at depth.
“These results combined with those reported for Cold Creek confirm our belief in the district scale potential throughout the Oakley Project.”
In total this year, 475 soil samples have been analyzed by Otis geologists for gold and silver from Blue Hill Creek. A further 140 rock-chip samples were collected across the target area and were analyzed for gold and silver. In all, 235 soil samples were taken from Emery Creek.
The Oakley gold-silver project is epithermal hot spring-type mineralization, which has been found in multiple areas.
Last month, Otis said it had found a 3.5 km long by 0.5 km wide silver and gold anomaly. The area lies at the north end of the group's Oakley project.
