PERTH ( – An updated disseminated mineral resource estimate (MRE) for the Black Swan project, in Western Australia, has resulted in a 48% increase in the contained nickel at the deposit, said ASX-listed Poseidon Nickel.

The project is now estimated to host an MRE of 26.3-million tonnes, at 0.72% nickel for 189 000 t of contained nickel, of which some 118 000 t is estimated in the measured and indicated category, a 48% increase on the previous estimate.

Compared with the 2022 resource estimate, the updated mineral resource also saw a 14% increase in the average nickel grade, an 8 000 t increase in total contained nickel, and provided increased confidence in the nickel grade distribution and the metallurgical characterisation of the mineralisation.

“Completion of the updated Black Swan disseminated resource and block model is an important milestone for the company, underpinning the project operating model as we move towards the final investment decision,” said Poseidon MD and CEO Peter Harold.

“Black Swan has a 2.2-million-tonne-a-year process plant and this resource upgrade is a key deliverable in our “Fill the Mill” strategy to leverage off the existing infrastructure and large resource base at Black Swan.”
