Charger confirms high-grade lithium at the Medcalf Spodumene Discovery

Charger Metals NL (ASX: CHR, “Charger” or the “Company”) is pleased to advise that assay results from the maiden drill programme, targeting spodumene-pegmatites at the Medcalf Spodumene Discovery within the Company’s Lake Johnston Lithium Prospect in the Yilgarn province of Western Australia, have returned high-grade lithium intersections in 14 of the 17 holes drilled in 2022.


Highlights:
  • First assays from the maiden reverse circulation (RC) drilling programme at the Medcalf Spodumene1 Discovery, have returned high grade2 lithium intersections.
  • Multiple stacked spodumene-pegmatites have been intersected within a 100m-wide zone, with an aggregated thickness of up to 12m.
  • Significant lithium intersections3 include:
    • 22CRC002: 5m at 2.55% Li2O4 from 68m including 2m at 4.19% Li2O
    • 22CRC005: 3m at 1.25% Li2O from 6m and
          • 6m at 1.52% Li2O from 26m and
          • 3m at 1.21% Li2O from 40m
    • 22CRC007: 5m at 1.86% Li2O from 24m and
          • 2m at 1.12% Li2O from 47m and
          • 4m at 1.83% Li2O from 56m and
          • 3m at 1.79% Li2O from 71m
    • 22CRC008: 5m at 1.12% Li2O from 52m
          • 1m at 4.02% Li2O from 63m; and
          • 2m at 1.74% Li2O from 84m
    • 22CRC009: 3m at 1.59% Li2O from 21m
    • 22CRC017: 6m at 1.16% Li2O from 93m; and
          • 4m at 1.27% Li2O from 200m
  • Drilling is continuing to test for extensions to the spodumene pegmatites1, both along strike and at depth.

Charger’s Managing Director, David Crook, commented:

The first very encouraging drilling results are now to hand and drilling is continuing to intersect similar multiple-sheet pegmatites within a plunging, 100m-wide, structural zone. The drill holes reported here confirm high grade lithium from surface down to a vertical depth of 210m, and the ongoing drill programme is expanding the extent of the spodumene-pegmatites along the strike direction and at progressively greater depths.”

Summary of the drilling programme and first assay results

The Medcalf Spodumene Discovery represents a swarm of anastomosing to tabular pegmatites hosted in sheared mafic amphibolite.

Medcalf spodumene-pegmatites are members of the lithium-caesium-tantalum (LCT) pegmatite family (albite-spodumene type).

Spodumene, which is clearly observed in many outcrops and supported by laboratory analyses, is the preferred mineral for the commercial production of lithium, a component of modern lithium batteries.

The current drilling programme saw 17 RC holes drilled during late 2022, and up to a further 23 holes to be drilled during January and February 20235.

The Medcalf Prospect is also being prepared for a programme of core drilling later this year, which can test for mineralisation at a depth greater than the current RC drilling rig’s capability.

Rio Tinto Shares Initial Resources and Ore Reserves for Rincon Lithium Project

Rio Tinto ( ASX:RIO,NYSE:RIO,LSE:RIO) released an initial mineral resources and ore reserves report for its 100 percent owned Argentina-based Rincon project on Wednesday (December 4).

Mineral resources inclusive of ore reserves comprise 1.54 million tonnes of lithium carbonate equivalent in the measured category, with 7.75 million tonnes in the indicated category and 2.29 million tonnes in the inferred category.

Probable ore reserves are made up of 2.07 million tonnes of lithium carbonate equivalent.
