Today, Sienna Resources Inc (TSXV:SIE) (A1XCQ0-FSE) (HBNRF-OTCBB) Clayton Valley Nevada lithium neighbour announced that “The Pure Energy and TBT team has achieved several intermediate milestones on the preliminary process engineering work for the Clayton Valley South (CVS) lithium brine project(full release below)”. Sienna has the property that is in the deepest sections of this basin that is the only basin in North America that is in production and Sienna has started work right beside Pure. Please refer to the map to see how Sienna is situated in the DEEPEST sections of this basin.
Management is very optimistic about Sienna as we have started operations. Sienna is in the deepest sections of the only basin in North America that is in production for Lithium. Sienna President Jason Gigliotti has recently purchased over 800,000 shares in the market between .21-.22 cents.
Pure Energy Minerals Ltd. is providing an update regarding its mini-pilot plant work with Tenova Bateman Technologies at its research and development centre in Katzrin, Israel, and at other off-site locations. The Pure Energy and TBT team has achieved several intermediate milestones on the preliminary process engineering work for the Clayton Valley South (CVS) lithium brine project:
- Brine pretreatment (LiP) testing exceeded expectations for lithium recovery and rejection of magnesium and calcium; two membranes have been shortlisted and are undergoing additional testing;
- Confirmed initial favourable results from the solvent extraction lithium recovery circuit (LiSX) — highly efficient lithium recoveries into solvent and very low levels of lithium in residual brine;
- Successful conversion of lithium sulphate into lithium hydroxide by electrolysis (LiEL) — achieving higher current efficiencies than anticipated.
The CVS mini-pilot plant program is beyond its halfway point, and progress has been excellent. This larger-scale study of Pure Energy’s proposed processing technology route for the CVS project is on track to highlight the advantages of a real-time new technology approach to lithium recovery. The team is advancing simultaneously on several areas of the program, as described in more detail below. All of these data will be integrated into the process design flow sheet and engineering studies that will comprise the company’s forthcoming preliminary economic assessment( PEA).
Patrick Highsmith, Pure Energy Minerals chief executive officer, commented: “We are very excited by our progress with Tenova Bateman Technologies on the mini-pilot plant. Last year’s preliminary test results showed the solvent extraction technology to be viable at bench scale, and this work is confirming success at a much larger scale while also providing engineering design data. As we reported in April of this year, the brine from our CVS project has among the lowest magnesium contents of any lithium brine resource in the world. This makes it well suited for new direct lithium extraction technology, such as the TBT process. We look forward to building on this interim technical success to highlight its potential for low-cost, highly sustainable and environmentally friendly lithium production technology.”
