Global Mining Review,

Atlantic Lithium Limited, the funded African-focussed lithium exploration and development company targeting to deliver Ghana’s first lithium mine, has announced the completion of the pre-feasibility study (PFS) on the Ewoyaa Lithium Project in Ghana, West Africa, demonstrating the significant profitability potential of this stand-out project.

The PFS was managed directly by the company, engaging experienced internationally recognised consultants, and incorporates the increased JORC resource of 30.1 million t at 1.26% Li2O, as announced on 24 March 2022.


  • Post-tax NPV8 of US$1.33 billion with free cash flow of US$2 billion from life of mine (LOM) revenues of US$4.84 billion.
  • Internal rate of return of 224% and payback less than five months, with average LOM EBITDA of US$248/yr.
  • Maiden ore reserve of 18.9 million t at 1.24% Li2O declared, demonstrating sound resource to reserve conversion.
  • 12.5-year mine life, 2 million tpy conventional dense media separation (DMS) processing facility with average 255 000 tpy 6% lithium spodumene concentrate (SC6) production.
  • C1 cash operating costs of US$278/t of SC6 free-on-board (FOB) Ghana Port, after by-product credits.
  • In addition to SC6 production, the PFS incorporates two additional revenue streams from by-products:
    • A saleable direct shipping ore fines product (DSO fines).
    • A saleable Feldspar by-product
  • Capital cost estimate of US$125 million, including integrated 3-stage crushing facility ahead of the DMS processing facility; a major design change to the scoping study concept of contract crushing, reducing plant OPEX, improving operational control and reducing lithium losses. 
  • Key assumptions: Long-term average SC6 price of US$1359/t FOB over 12.5 years, project funding via Piedmont agreement and cost estimation at +/- 20% level of accuracy.

Commenting on the company’s latest progress, Lennard Kolff, Interim Chief Executive Officer of Atlantic Lithium, said:

“We are delighted to release our PFS for the Ewoyaa Lithium Project in Ghana, which further illustrates Ewoyaa as an industry-leading lithium asset, generating in excess of US$4.84 billion in revenues over a 12.5-year mine life.

"The study outlines a robust 2 million tpy operation which can deliver excellent cash flows, an exceptional 20-week payback and a post-tax NPV8 of US$1.33 billion producing a coarse, premium DMS SC6 product including credits from DSO fines and feldspar by-products.

“The study used a long-term average SC6 price of US$1359/t FOB Ghana, with recent equivalent grade prices as high as US$7708/t being achieved on Pilbara Minerals Limited BMX platform and representing a mid-range forecast when compared to other commentators.

“Every US$100/t increase in SC6 price forecast results in an additional 9% increase to the post-tax NPV8, highlighting the significant potential value uplift to the Project.

“We are also pleased to declare a maiden ore reserve of 18.9 million t at 1.24% Li2O, presenting sound resource to reserve conversion and confirming the robust project fundamentals.
