Vancouver, BC, October 22, 2013 - Adamera Minerals Corp. (TSX V: ADZ) announces that it has identified a second high priority gold target area on the Poland China property in Washington State. This second area, located 1.5 kilometres north of the historic Poland China mine, is marked by extensive historic "placer" mine workings that extend for about 500 metres.
Recent work completed by Adamera suggests that gold found in soil in this new area may not be part of an actual placer deposit, and may be residual gold derived from shallow, underlying weathered bedrock. The original nearby Poland China Mine was discovered over 100 years ago by farmers who accidently found gold in the roots of grass.
Coarse gold grains up to 2 mm in size were recovered from soil in this area by hand panning. The gold grains examined under binocular microscope exhibit primary textures, which suggests a nearby bedrock source. These textures include sharp angularity of gold grains and the presence of gold grains with quartz still attached to them. Washington Department of Natural Resources geologists documented similar observations.
Placer gold occurrences typically form in river or stream sediments where the gold has been concentrated by moving water. In this new area, gold occurs in a silty soil that has apparently not undergone a concentrating process. For historic mining of this gold bearing soil to have been economically viable, the gold content of underlying bedrock must have been significant.
The presence of pathfinder elements associated with gold on the property also supports the existence of a nearby bedrock source. These pathfinder elements are found in sulfide minerals that typically deteriorate as they travel farther from their source. In this new target area, the preservation of pathfinder elements has been interpreted to reflect underlying bedrock mineralization.
"Almost every significant gold deposit in the Cordilleran has an associated nearby placer component. The "placer" gold occurrence at the Poland China property has been previously overlooked with regards to originating from a nearby bedrock source, and we now recognize it as being far more important than initially thought. It is unusual to find this high concentration of coarse local gold in unsorted soil. This, along with the Poland China Mine and the many other showings and anomalies found elsewhere, demonstrates how widespread gold mineralization is on the property," says Mark Kolebaba President and CEO of the company. "This second gold occurrence is well-suited to excavator trenching due to the shallow depth to bedrock in much of the area and the private land status".
Jim Ebisch, P.Geol is a Qualified Person as defined by National Instrument 43-101 reviewing the data in this release. Gold grain review under binocular microscope and handheld XRF analysis of soil samples was conducted by the company.
Adamera's strategy in Washington State is to discover high-grade gold mineralization near established infrastructure. Specifically, the company is targeting areas near the Kinross Kettle River Mill. The Kinross mill is reported to be operating at half capacity with ore shipped 70 kilometres from the 1.3 million ounce Buckhorn mine which has only 2 years mine life remaining. Average grade of the Buckhorn mine is 11.3 g/t gold and production costs are reported to be between $420 and $500 per ounce. The Poland China property is only 80 kilometres by road to the Kinross Mill.
