Name of the Project
Ewoyaa lithium project.

Location
Ghana.

Project Owner/s
Aim-listed lithium explorer and developer Atlantic Minerals. Piedmont has an earn-in right of 50% of Atlantic’s Ghanaian projects, including Ewoyaa, and the company holds a 10% equity interest in Atlantic Lithium.

Project Description
A prefeasibility study (PFS) has delivered robust project economics. The project includes the Ewoyaa, Abonko and Kaampakrom deposits.

The project has probable ore reserves of 18.9-million tonnes grading 1.24% lithium oxide.

A contract mining operation is proposed, owing to an abundance of experienced, well-established local contractors in Ghana.

The PFS envisages an openpit mining operation with a 12.5-year mine life, which includes a two-million-tonne-a-year conventional dense-media separation processing facility producing about 255 000 t/y of 6% lithium spodumene concentrate (SC6).

Life-of-mine production is estimated at 3.18-million tonnes.

In addition to SC6 production, the PFS incorporates two additional revenue streams from by-products – a saleable direct shipping ore (DSO) fines product and a saleable feldspar by-product.

DSO is estimated at 3.74-million tonnes and feldspar at 4.12-million tonnes.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has a pretax net present value, at an 8% discount rate, of $1.33-million and an internal rate of return of 224%, with a payback of less than five months.

Capital Expenditure
Capital expenditure has increased from $70-million in the scoping study to $125-million in the PFS, as a result of the crushing being done in house as opposed to outsourcing it.

Planned Start/End Date
The proposed project development programme targets first production of SC6 in the third quarter of 2024, based on receiving a mining licence in the third quarter of 2023, which, in turn, is subject to meeting all statutory requirements.

Latest Developments
None stated.
