MOORCROFT -- Strata Energy, Inc. has submitted a request to the Wyoming Department of Environmental Quality to amend its Permit to Mine to allow for the use of low-pH recovery solution in the Ross Permit Area of the Lance Projects near Oshoto, in the northeastern corner of the state.
The permit to mine for the Lance Projects currently authorizes the use of alkaline and oxidant solutions in the in-situ recovery process.
Since uranium recovery efforts commenced in December 2015, the ore deposit at the project has proven only moderately amenable to these alkaline solutions, although below targeted levels.
A successful transition to low-pH operations could align the operating performance and cost profile of the Lance Projects with current industry leading global uranium production projects.
No changes have been requested to the target restoration values previously approved for each mine unit.
