Nimy Resources’ (ASX: NIM) maiden lithium drilling at the Mons Project in Western Australia has revealed extensive pegmatite discoveries beneath significant lithium soil anomalies, covering a strike length of 19.4km.

Pegmatite Intersections

The drilling program targeted the South Lake and Royale prospects, which were identified following soil sampling results returning anomalous lithium levels of up to 232 ppm Li₂O and 131ppm Li₂O respectively. These results were significantly higher than previous soil sampling data and comparative benchmarks.

Pegmatites were intersected in all eight holes drilled at Royale for a total strike of 1.3 kilometres, with the maximum pegmatite interval measuring 189 metres in hole NRRC083. Similarly, at the South Lake Prospect, pegmatites were intersected in ten out of twelve drill holes over a 640-metre strike, with the thickest interval being 187 metres in hole NRRC080.

Notable intersections at the Royale Prospect included:

  • NRRC082 (168m from 72m)
  • NRRC083 (189m from 64m)
  • NRRC084 (176m from 64m)
  • NRRC085 (147m from 48m)
  • NRRC086 (153m from 75m)
  • NRRC087 (113m from 75m)
  • NRRC088 (170m from 54m)
  • NRRC089 (125m from 72m)

Notable intersections at the South Lake Prospect included:

  • NRRC078 (172m from 68m)
  • NRRC079 (159m from 81m)
  • NRRC080 (187m from 53m)
  • NRRC081 (110m from 34m)

All samples collected have been submitted for assay, including both 4 metre composite and 1 metre intervals within mineralised zones.

Operational Updates

The Company also shared an operational update on the Mons Project, announcing the completion of the initial phase of the reverse circulation drilling program. The program consisted of 70 holes spanning 16,783 metres.

Samples collected during drilling are currently undergoing geochemical assaying at Intertek Laboratories in Kalgoorlie or Perth. Once the assay results are received, Nimy plans to proceed with infill drilling and comprehensive geological logging.

Located in the Karroun Hill district of the Forrestania belt, the Mons Project covers a significant land area with approved and pending tenements. The Project’s geological setting within nickel-rich komatiite sequences offers potential for both nickel and other valuable metals crucial for the decarbonisation of the economy.

Looking Forward

The positive findings have bolstered confidence in the efficacy of lithium soil sampling as an exploration tool at the Mons Project with the Company now planning to extend the soil anomaly, which remains open along the strike, and is considering follow-up drilling.

“To intersect such extensive pegmatites below a strong lithium soil anomaly is highly promising. Favourable assays would confirm that the soil sampling is an effective lithium exploration tool at Mons and in this event we will move quickly to expand the anomaly, which remains open,” Geological Consultant Fergus Jockel said.

Nimy Resources Australian Stock Exchange-listed share price has surged 63.83% in response to the announcement and is currently trading at 38 cents (12:28 pm UTC+ 8 hours).
