Pure Energy Minerals Limited (TSX-V:PE) (FRANKFURT:A111EG) (OTCQB:PEMIF) (the “Company” or “Pure Energy”) is pleased to announce that it has completed a constant-rate pumping test at its newest exploration well, CV-7. The test ran continuously for two days and included collection of brine samples along with extensive hydrogeological data on the brine aquifer system. The pumping test was designed and supervised by Pure Energy’s hydrogeological consulting specialists, Montgomery & Associates (“Montgomery”). This successful test of CV-7 provided valuable additional data for Pure Energy’s technical team to advance and refine its understanding of the Clayton Valley South (CVS) lithium resource.
The pumping test was configured using an electric submersible pump and monitoring apparatus in CV-7, and ran at a constant pumping rate of approximately 5 litres per second (80 gallons per minute) for its duration. The hydrogeologists collected approximately 32 separate brine samples (including QA/QC samples) for lithium analysis over the 48-hour pumping period. Monitoring revealed that the extracted brine from CV-7 reached near steady-state elevated fluid conductivity and fluid density, comparable to other brine wells on the CVS Project. This suggests the production of consistent lithium-bearing brine during the entire pumping test. Detailed, depth-specific brine samples have also been collected from the well, and the analytical results are expected by mid-March. The upcoming Preliminary Economic Assessment (PEA) will include a full discussion and interpretation of the data from CV-7.
Patrick Highsmith, Pure Energy Minerals CEO commented, “Now that the Phase 3 drill program has concluded, it is gratifying to see the data collection finish on a strong note. The pumping test at CV-7 went very smoothly and we expect to test CV-8 very soon. The team has steadily improved in our ability to execute on deep drilling, well construction, sampling, and the all-important hydrogeological test work. We are processing the data from this most recent test, and we shall incorporate the technical parameters, along with the lithium content of the brine from CV-7 into the upcoming resource update.”
This pumping test was performed in accordance with State of Nevada waivers and permits issued to Pure Energy by the Nevada Division of Water Resources and the Division of Environmental Protection, which allowed for the extraction of brine from the well and subsequent discharge to surface.
