28 May 2026 | South Australia - Marmota has reported strong new gold assay results from the Greenewood discovery, part of its Gawler Craton Gold Project in South Australia.

The latest results come from Stage 2 of Marmota’s maiden drilling program at Greenewood and include detailed 1m split assays following earlier 4m composite results announced in February. Marmota said the results continue to grow the discovery, with mineralisation remaining open along strike and at depth.

New high-grade 1m assays include:

  • 41 g/t gold from 82m downhole in hole 25GWRC241
  • 40 g/t gold from 84m downhole in hole 25GWRC249
  • 28 g/t gold from 74m downhole in hole 25GWRC215
  • 27 g/t gold from 86m downhole in hole 25GWRC210
  • 26 g/t gold from 36m downhole in hole 25GWRC208
  • 26 g/t gold from 96m downhole in hole 25GWRC253

Across Marmota’s maiden Stage 1 and Stage 2 program at Greenewood, the company has now reported 6 intersections over 40 g/t gold, 18 intersections over 20 g/t gold, 55 intersections over 10 g/t gold and 119 intersections over 5 g/t gold.

Marmota said Stage 2 has been particularly encouraging because it was a smaller program than Stage 1, with 10,117m of drilling compared with 15,480m in Stage 1, yet still delivered a large number of high-grade results.

The company highlighted several broader intersections from the maiden program, including 12m at 5.4 g/t gold, 5m at 10 g/t gold, 9m at 7.1 g/t gold, 8m at 6.1 g/t gold, 21m at 2.6 g/t gold, and earlier Stage 1 results including 33m at 10 g/t gold and 22m at 5.1 g/t gold.

Why it matters: Greenewood is emerging as a significant high-grade gold discovery in South Australia’s Gawler Craton. Marmota said the results show the development and extension of multiple high-grade zones, particularly to the northeast along strike, with the orebody extending in multiple directions and remaining open.

The company said the maiden program has delineated a nearly continuous high-grade mineralised system, with bonanza gold grades close to surface and continuity along strike. A follow-up Stage 3 RC drilling program has already commenced, targeting major extensions at Greenewood and the southern Mainwood area, with the aim of potentially extending the system’s strike to around 2km.

Greenewood is located about 35km northwest of Marmota’s Aurora Tank gold deposit and about 30km northeast of the Challenger Gold Mine. The project is part of the Golden Moon JV, where Marmota holds a 90% interest.

Marmota Chairman Dr Colin Rose said Greenewood “keeps growing and getting better” with each stage of the maiden program, adding that Stage 3 drilling is already underway and progressing well.

For South Australia’s gold sector, the results add further momentum to the Gawler Craton, where Marmota is building a broader gold project around Greenewood, Aurora Tank and other nearby deposits.
