Geology & Mineralisation

PGM’s Mining Lease covers approximately 37.84 hectares and contains what is currently the only known large Green Chert deposit in Western Australia. Geological mapping has identified a continuous mineralised zone extending approximately 500 metres in length and 200 metres in width. Based on current geological interpretation, the jade-bearing formation is considered to continue to an estimated depth of approximately 200 metres. The material has an in-situ specific gravity of approximately 2.68.

These dimensions are derived from geological mapping and are provided to illustrate the scale and geometry of the mineralised system. They do not constitute a Mineral Resource or Ore Reserve estimate and have not been prepared in accordance with the JORC Code. Any future Mineral Resource estimate will require systematic drilling, representative sampling, laboratory testing and independent geological evaluation.
