Nick Winer

Chief Operating Officer

B.Sc. Hons, Macquarie Univ. Australia

Nick has had a successful career and made discoveries with BHP Exploration, Horizonte Minerals and AngloGold Ashanti. In 2013 he led the AngloGold Colombian team that discovered and then delivered the resource model and Scoping Study for the “blind”, Nuevo Chaquiro Cu/Au deposit. This world class deposit starts 250m below the surface and contains 8Blbs of copper and 5.6Mozs Au with significant Ag & Mo credits (*). The discovery of the high grade zone in 2014 was the result of developing and deploying an integrated exploration dataset together with the knowledge and experience of the team.

Nick’s technical expertise in exploration and experience in Colombia, combined with a drive to make discoveries, make him a valuable asset to the management team where he will lead the Company’s exploration activities, in particular the advancement of the portfolio of gold assets in the Quinchia district.
