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.

• 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.
