Australian uranium miner Bannerman Resources has extended its preliminary feasibility study (PFS) on the Etango uranium project in Namibia to take into account recent positive developments, the company said.

The extended study will focus on the recently announced increase in mineral resources at the site.

It will also consider the impact of larger sized heap leach test results, which have indicated faster leach kinetic and can improve operating flexibility and project economics, Bannerman said.

The effect of recent preliminary flotation beneficiation tests, which can materially influence the choice of processing route, will also be investigated.

The delay in the release of the PFS from the current quarter will enable the company to fully evaluate the favourable results obtained from recent tests, Bannerman CEO Len Jubber said.

“While we had initially planned to release the results of the preliminary feasibility study in the current quarter, we feel the recent favourable results obtained from continued heap leach test work and, in particular, from flotation test work, are significant for Bannerman and demand to be fully evaluated prior to finalising the preferred processing flow sheet,” Jubber said.
