Web30 mrt. 2024 · Assay results from drillholes 3-6 🔄. With the first two drillholes containing high grade lithium oxide, we will be watching to see these high grades continue along strike in drillholes 3-6. Noting that defined hard rock lithium deposits generally have grades between 1-1.5%, we expect to see the grades come down as the project size increases. WebMaterial and Methods: Serum lithium levels were measured with spectrophotometric and ISE methods. The performances of both methods in measurement of lithium were evaluated. Results: Between-run and within-run coefficient of variations (CV) for both assays were evaluated using commercial controls (Data-Trol Abnormal and Normal).
