Investor Presentation – Prieska Project Bankable Feasibility Study – Mining Journal Select 2019 Orion Minerals Limited Incorporated in the Commonwealth of Australia Australian Company Number 098 939 274 ASX share code: ORN JSE share code: ORN ISIN: AU000000ORN1 (“Orion” or “the Company”) INVESTOR PRESENTATION – PRIESKA PROJECT BANKABLE FEASIBILITY STUDY – MINING JOURNAL SELECT 2019 On 24 June 2019, Orion Minerals Ltd (ASX/JSE: ORN) (Orion or Company) announced the positive outcomes of a Bankable Feasibility Study for the Foundation Phase of its Prieska Copper-Zinc Project (Prieska Project), located in the Northern Cape Province of South Africa (BFS). The BFS results highlight that the Prieska Project is a long life, high margin copper and zinc development project, with exceptional opportunities for future growth. Based on the BFS assumptions, the Project will provide excellent financial returns, for a relatively modest capital investment, given the scale of operations envisaged and the fact that the new production hub is located within a highly-endowed but under-explored volcanic massive sulphide district, with significant long-term exploration potential. Orion’s Managing Director and CEO, Mr Errol Smart is presenting today at Mining Journal Select 2019, in London.
