William B. Earnshaw

Consultant- Milling and Extraction Processing New Enterprise, Marco & Gold Lake

Bill Earnshaw is the Company’s milling and extraction consultant, on the New Enterprise, Marco and, Gold Lake Projects. Mr. Earnshaw has been a designer and innovator of extraction methods and refining techniques in precious metals recovery for the bulk of his 37 years in mining. He has responsible for substantial work on devising and establishing extraction and recovery methodologies on ore from Pershing Resources current properties. He started his career in a small gold refinery in Carson City, Nevada, where he learned the basic principles of extraction and recovery techniques and moved on to work on numerous projects in the US and South America. In 1984, he developed and built portable, hydraulically driven placer plants to make placer mining more accessible to the small miner. In 2002, he developed a hydrogen fire assay and successfully extracted precious metals that were not found in chemical or standard fire assays methods. This work led him to focus more efficient commercial recovery techniques. He formed Simple Recovery Inc. in 2003 to pursue this work. He has since researched, developed and scaled up many methods to increase recovery rates on complex ores. Mr. Earnshaw has also pioneered the use of environmental/green innovations and cost effective practices in the mining and milling operations he has developed. Pershing Resources purchased Simple Recovery in May of 2015.
