Stria Lithium Metallurgical Tests Yield Recovery of 53.9% Li

Stria Lithium Inc. (TSXV:SRA) reported that its dense media separation study demonstrates that the Pontax mineralization can generate an initial spodumene concentrate recovery of 53.9% Li grading at 6.03% Li2O. This confirms the viability of feedstock for the 2015 pilot plant. The Pontax Lithium Project is in the James Bay Region of Northern Quebec.

As quoted in the press release:

Mineralogical and metallurgical testing was undertaken by SGS Canada at their Lakefield, Ontario facilities. It included sample preparation, head sample analysis, mineralogical analysis, heavy liquid separation (“HLS”) tests and the grindability characterization. Upon completion of the gravity separation tests, dense media separation and magnetic separation were conducted to improve the grade and recovery of the spodumene.

SGS reported that conventional HLS processes indicated the Pontax mineralization can generate an initial spodumene concentrate recovery of 53.9% Li grading at 6.03% Li2O. With fine portions added, the total spodumene concentrate is capable of achieving 94.9% Li purity.

Work continues at SGS using a small parallel flotation circuit to upgrade the middlings and to improve overall recoveries and lithium purity. HLS testing also demonstrated it was possible to reject 61% of the original mass as mainly silicate gangue with a resulting Li loss of only 5.1% of that mass.

Stria President and Chief Operating Officer Julien Davy said:

We are very pleased with these metallurgical test results. They confirm our Pontax spodumene mineralization is a viable feedstock for a planned 2015 pilot plant.
