NewCastle Gold has a 100% interest in the Castle Mountain property in San Bernardino County, California. The Castle Mountain heap leach gold mine produced over one million ounces of gold from 1992 to 2004. The Mine and Reclamation Plan, under which the mine operated, was authorized by the County of San Bernardino as the Lead Agency and remains in effect. Water for the current drill programs was accessed from existing patented wells on the Project.
An updated NI 43-101 resource for the project was announced September 11, 2017 which includes Measured Mineral Resources of 135.0 million tonnes grading 0.64 g/t gold containing 2.8 million gold ounces, Indicated Mineral Resources of 57.2 million tonnes grading 0.64 g/t gold containing 1.2 million gold ounces along with Inferred Mineral Resources of 102.3 million tonnes grading 0.48 g/t gold and containing 1.6 million gold ounces.
The Project hosts a disseminated low sulphidation epithermal gold system. Gold is primarily hosted by late-stage rhyolite volcanic units within zones of silicification and brecciation associated with north to northeast trending/southeast dipping fault structures.
