- Initial mineralogy completed on select samples from drill holes CF21-001 and 002 (CV5 Pegmatite), 004 (CV6 Pegmatite), and 014 (CV12 Pegmatite), indicate:
- Spodumene is the dominant lithium-bearing mineral present – of the samples probed grading >0.4% Li2O, spodumene accounts for 86-99% of the lithium deportment
- No significant petalite, lithium-phosphate minerals, or apatite present
- Columbite/tantalite are the dominant tantalum-bearing minerals present
- Preliminary Metallurgical program initiated at SGS Canada (Lakefield) supported by 225 kg of sample drill core from holes CF21-001 and 002 at the CV5 Pegmatite
- Primary objective is to develop preliminary flowsheet to produce spodumene concentrate – grading >6% Li2O – at high recovery
- Focused on head sample characterization and mineralogy, grindability, heavy liquid separation (HLS), dense media separation (DMS), magnetic separation, and flotation
Patriot Battery Metals Inc. (the “Company” or “Patriot”) (CSE: PMET) (OTCQB: PMETF) (FSE: R9GA) is pleased to announce the results of initial mineralogical characterization of drill core samples from the Company’s wholly owned Corvette Property (the “Property”), as well as the commencement of a preliminary metallurgical test program. The Property is located proximal to the regional and all-weather Trans-Taiga Road and powerline infrastructure, within the James Bay Region of Quebec.
Initial mineralogical work was completed by SGS Canada on twenty-two (22) drill core analytical reject samples collected across four (4) of the first five (5) drill holes to target lithium pegmatite in 2021 – CF21‑001 and 002 (CV5 Pegmatite), CF21-004 (CV6 Pegmatite), and CF21-014 (CV12 Pegmatite). All samples were analyzed by XRD (X-ray diffraction) for modal mineralogy, four (4) samples by TIMA-X (Quantitative Evaluation of Materials by Scanning Electron Microscopy) for mineral associations and elemental deportment, and four (4) samples by Electron Probe Micro-Analysis (EPMA) and Laser Ablation by Inductively Coupled Plasma Mass Spectrometry (LA by ICP-MS) for mineral chemistry. The purpose of the mineralogy work is to provide a preliminary characterization of the lithium pegmatite at Corvette, and to orient ahead of preliminary metallurgical (mineral processing) test work.
The modal mineralogies for the pegmatites, as determined by XRD, support geological core logging. The major minerals include quartz, feldspar (albite, microcline), and spodumene, with minor to accessory muscovite and tourmaline. Uncommon accessory minerals (typically <3% if present) include lepidolite, chlorite, biotite, and beryl.
The combined results of the mineralogy and mineral chemistry indicate that spodumene is the dominant lithium-bearing mineral at Corvette. No petalite or lithium phosphate minerals were observed from XRD; although, trace to minor lepidolite (Li mica) and lithium bearing muscovite and tourmaline are present in some samples. However, where spodumene is present, it is the dominant lithium-bearing mineral. Moreover, of the samples probed grading >0.4% Li2O, spodumene accounts for 86-99% of the lithium deportment, further supporting that lithium grade is carried by spodumene. Collectively, these preliminary results indicate that the mineral spodumene carries the vast majority of the lithium at Corvette and supports the visual observations by the field geologists.
An additional suite of core billets and analytical rejects are being compiled for follow-up mineralogical analysis that will include XRD, TIMA-X, EPMA, LA by ICP-MS, as well as thin section analysis. The work will improve the understanding of the pegmatites at Corvette and guide metallurgical test programs.
In addition to the initial mineralogical work, a preliminary metallurgical test program is now underway at SGS Canada’s Lakefield, ON, facility. Approximately 225kg of quarter-core NQ samples, comprising mineralized intervals from drill holes CF21-001 and 002, have been received by the lab for the initial testwork. Material preparation has recently been completed and test work begun.
The testing is anticipated to include head sample characterization and mineralogy, grindability, heavy liquid separation (HLS), dense media separation (DMS), magnetic separation, and flotation. The primary objective of the preliminary metallurgical program is to evaluate the beneficiation performance of the Corvette material using a conventional lithium pegmatite flowsheet, and to produce a spodumene concentrate of >6% Li2O and <1% Fe2O3, while maximizing lithium recovery.
About the CV Lithium Trend
The CV Lithium Trend is an emerging spodumene pegmatite district discovered by the Company in 2017 and spans the FCI West, FCI East, and Corvette claim blocks. The core area includes an approximate 2 km long corridor (the CV5-1 Corridor), which is part of the more than 25-km long CV Lithium Trend extending across the Property. It consists of numerous spodumene pegmatite occurrences, which include the CV1, CV2, CV3, CV5, CV6, CV7, and CV11 pegmatites and has returned drill intercepts of 0.94% Li2O and 117 ppm Ta2O5 over 155.1 m (CF21-002), and 2.22% Li2O over 70.1 m, including 3.01% Li2O over 40.7 m (CV22-017). Drilling to date indicates a principal pegmatite body of significant size and has been traced by drilling over a distance of at least 1.4 km, and therefore, is considerably larger than that observed in outcrop. The high number of well-mineralized pegmatites in this core area of the trend indicate a strong potential for a series of relatively closely spaced/stacked, sub-parallel, and sizable spodumene-bearing pegmatite bodies, with significant lateral and depth extent, to be present.
