Exploration Manager

Mr Groombridge is an experienced geoscientist with more than 20 years’ experience in mineral exploration, resource development and project evaluation.

His previous roles include Exploration Manager at Medallion Metals (ASX: MM8); Chief Executive Officer of Riedel Resources (ASX: RIE) and Senior Geologist at Silver Lake Resources (now a subsidiary of Red 5 Limited).
