Name of the Project
Orom-Cross graphite project.
Graphite, nickel and copper developer Blencowe Resources.
A prefeasibility study (PFS) has highlighted an exceptional long-life project that delivers considerable returns over an initial life-of-mine of 14 years.
An estimated 600 000 t/y of ore will be mined from the commissioning date and this will increase to 2.4-million tonnes a year by the time the project is fully ramped up in Year 10.
Mining will be free-dig, with no drill-and-blast required. Initial ore will come from saprolite (clay) at about 15 m to 20 m depth on average. Both deposits (Northern syncline and Camp lode) identified in the drilling programmes will be mined and a composite blend of both will be fed into the processing plant that will be built on site.
An initial 36 000 t/y of end-product will be delivered from the plant as concentrates, which will increase in two additional stages to 147 000 t/y once the mine is fully ramped up.
Further resources, higher production volumes and an extended mine life can all be obtained at any stage by drilling additional ready-targets. This, however, is not currently considered a priority.
The processing flowsheet comprises a flash and rougher flotation stage, followed by a primary cleaning circuit with a polishing mill and three stages of cleaner flotation. The intermediate concentrate is classified and then further upgraded in secondary cleaning circuits with stirred media mills, followed by cleaner flotation.
Orom-Cross will deliver at least five different end-products, characterised by size fractions of +50 mesh, + 80 mesh, +100 mesh, +150 mesh and -100 mesh. These products will have different markets and will be branded and packaged at site.
Initially, transport to port will be by road, but it is expected that a rail option might be available nearby by 2025, further reducing logistics costs.
Potential Job Creation
Net Present Value/Internal Rate of Return
The project has an after-tax net present value, at an 8% discount rate, of $482-million and an internal rate of return of 50%.
The initial capital requirement has been lowered by 23% to $62-million since the preliminary economic assessment was announced in 2021.
Planned Start/End Date
Blencowe will start the main operations from 2025 at an initial output of 36 000 t/y of end-product.
Blencowe Resources has raised £635 000 through the issue of 12.7-million new shares to maintain momentum on the definitive feasibility study (DFS) that is under way at the Orom-Cross graphite project.
Work on the DFS began early this year and is being managed by CPC Engineering.
Blencowe recently announced that it had passed the key screening hurdles by the Development Finance Corporation (DFC) regarding a $4.5-million technical assistance grant to fund 50% of the DFS. The company expects to complete the process of obtaining the grant with DFC over the coming weeks and then draw down funds for the DFS work.
The net proceeds of the capital raise enable Blencowe to avoid an immediate delay to the DFS programme while the DFC grant is being finalised.
Key Contracts, Suppliers and Consultants
