Name of the Project
Okiep copper project (OCP).
Northern Cape, South Africa.
In July 2021, Orion exercised its exclusive option to acquire a controlling interest in several of the properties comprising the OCP.
Orion has also applied for additional prospecting rights to supplement the OCP mineral rights. The mineral rights are intended to be held by two newly formed Orion companies – New Okiep Exploration Company (initially 100% Orion) and the New Okiep Mining Company (initially 56.3% Orion and 43.7% Industrial Development Corporation, or IDC). Both companies will, in future, include empowerment partners in compliance with Mining Charter 2018.
A scoping study completed in May 2021 has proposed a proof-of-concept-scale copper mining operation at the brownfield OCP, and has confirmed that the project’s deposits have the potential to be mined at low cost using openpit and underground mining methods.
The outcome of the scoping study, based on five initial deposits, supports the economic merit of developing a foundation-phase mining operation, while Orion conducts the required work and engineering studies to evaluate the potential to re-establish mining operations.
The life-of-mine for the proof-of-concept foundation phase is modelled for 12 years, during which concurrent exploration and mine expansion scenarios will be planned and potentially implemented.
The proposed foundation-scale mining operations could run at a design processing plant throughput of 780 000 t/y, resulting in 9 000 t/y of copper sold in marketable concentrates. This could potentially supplement the 23 000 t/y of copper production planned from Orion’s flagship Prieska copper/zinc project.
Underground and surface mining methods will be used in conjunction with mineral processing using conventional froth-flotation concentration to produce the copper concentrates for export.
The proof-of-concept phase of the proposed operation targets the development of only those Okiep copper deposits for which Orion has verified and reported mineral resources during the early phase of the due diligence period. The milled production target comprises a measured mineral resources of 33%, indicated mineral resources of 46% and inferred mineral resources of 21%.
Potential Job Creation
Net Present Value/Internal Rate of Return
The project has a pretax net present value, at a 10% discount rate, of R1.9-billion and an internal rate of return of 44%, with a payback from first production of 3.25 years.
Peak funding is estimated at R643-million.
Planned Start/End Date
First production is possible within 16 months from the start of construction.
Orion Minerals has announced plans to raise up to A$20-million in a three-tranche share placement to sophisticated and professional investors.
Orion has received firm commitments for the first two tranches, which will raise a combined near A$6-million.
Priced at 2c a share, the first tranche of the placement will comprise 156-million shares, raising an initial A$3.1-million under the company’s existing 15% placement capacity.
The second tranche of 145-million shares will raise a further A$2.9-million, with chairperson Denis Waddell and nonexecutive director Tom Borman subscribing for a combined A$2.2-million in shares.
The second tranche placement will be subject to shareholder approval.
Part of the capital raised will be used to progress a feasibility study on the Okiep copper project.
