[{"type":"text","content":" Highlights Heavy Liquid Separation (“HLS”) testwork on eleven (11) core sample composites indicate that a Dense Media Separation (“DMS”) process is applicable to the greater CV5 Pegmatite body. HLS sample head grades ranged from 0.67% to 2.73% Li2O, resulting in an average spodumene concentrate grade of 5.98% Li2O at 77% recovery. Results affirm previous HLS and DMS results and bolster confidence that a simple DMS driven flowsheet, without the need of flotation, is applicable to the greater CV5 Pegmatite. Testwork indicates that a marketable spodumene concentrate exceeding 5.5% Li2O at high 70’s recovery is achievable using a DMS process. Five (5) composite samples have been selected from the CV13 Pegmatite for HLS testing to evaluate the potential of DMS on this material. Mineral Process Consultant and Project Steering Group member, Brett Grosvenor, comments: “The results of this HLS testwork, which encompasses a wider sampling of the overall CV5 Pegmatite, are very positive and give us a strong confidence that DMS will be applicable to the CV5 Pegmatite as a whole. These results demonstrate similar liberation and process characteristics are present across the pegmatite body at various depths along its length, along with high lithium recoveries in-line with the prior HLS and DMS work. Collectively, the results of the test program provide a strong ‘vote of confidence’ in a simple DMS process plant design without the need for flotation.” SYDNEY, Australia, Feb. 21, 2023 (GLOBE NEWSWIRE) -- Patriot Battery Metals Inc. (the “Company” or “Patriot”) (TSX-V: PMET) (ASX: PMT) (OTCQX: PMETF) (FSE: R9GA) is pleased to announce the results of the Heavy Liquid Separation (“HLS”) Phase II testwork program on CV5 Pegmatite material, completed as follow-up to the successful Phase I HLS and Dense Media Separation (“DMS”) testwork program (see news release dated December 19th, 2022). The prior Phase I HLS and DMS testwork, completed on CV5 Pegmatite material from drill holes CF21-001 and 002, affirm that bench scale HLS testing is a cost-effective way to rapidly assess the applicability of larger scale DMS processing, which is more reflective of an operating and continuous process (Table 1). As a next step, the HLS testwork program was expanded (i.e., Phase II) with the objective to assess the liberation and recovery characteristics of spodume...
