Peninsula Energy secures approval to begin low pH uranium recovery process trial

Preparation work for the field leach trial is being conducted on site and the trial is expected to commence in late 2018.
Trial demonstration is expected to run for six to eight months

Peninsula Energy Ltd (ASX:PEN) has secured approval from the Wyoming Department of Environmental Quality (WDEQ) for a non-significant revision (NSR) to its existing Permit to Mine (PTM) related to testing low pH lixiviant for suitability as a uranium recovery process.

The NSR authorises Peninsula to conduct field trials using low pH lixiviant at the Lance Projects in Wyoming, US.

This approval follows a submission by the company to the WDEQ requesting authorisation of a small-scale field demonstration.

In addition, the WDEQ continues to conduct its review of Peninsula’s requests to amend the existing PTM and Source Material and By-product License (SML).

Preparation work for the low pH field leach trial is being conducted on site and it is anticipated that the trial will commence in late 2018.

The planned trial demonstration comprises both mining and restoration phases and is expected to run for six to eight months.

Designated field trial areas

Peninsula managing director and CEO Wayne Heili said: “This authorisation from the WDEQ enables us to validate in a limited field operating environment the successful low pH results that we have obtained under laboratory conditions.

“Importantly, we may conduct the field demonstration concurrently with the WDEQ progressing their reviews of our major amendment requests, providing both parties timely, valuable operating insight and data.

“This approval to commence a low pH field demonstration is a very positive step forward for the company and potentially allows for a faster ramp-up of low pH operations.”
