• New assays for 13 of 28 drill holes have returned results up to 3,160ppm TREO, adding to the 5,125ppm TREO intercept from maiden drilling at Destiny
  • High-value magnet rare earth oxides such as NdPr comprise a high percentage of TREO, 19% on average across all drill holes
  • Priority is now on further exploration and resource definition drilling


Special Report: A follow-up drilling program completed earlier this month at St George’s Destiny project in WA’s Eastern Goldfields has confirmed further continuity of the clay-hosted REE discovery announced in December 2023.

The maiden drilling program confirmed high-grade total rare earth (TREO) mineralisation across a strike of 7km along the Ida Fault, a regional scale crustal shear zone gaining popularity as a control on major mineral deposits in WA.

Rare earth elements such as neodymium and praseodymium are needed for the permanent magnets used in electric vehicle motors and wind turbines – two markets expected to drive a more than doubling in demand by 2030.

Together with the scale of the prospective geology, which St George Mining (ASX:SGQ) believes could extend for more than 70km, the ‘ground-breaking results’ revealed for the first time the impressive potential of the project.

Now, the most recent follow-up drilling campaign – comprising a total 28 drill holes – has been successful again, this time in identifying continuity in the distribution of TREO zones.

Strike of more than 10km

New standout results include:

  • 34m @ 1,363ppm TREO, 245ppm MREO from 12m including 3m @ 2,910ppm TREO, 550ppm MREO from 41m;
  • 30m @ 1,581ppm TREO, 310ppm MREO from 19m including 3m @ 2,629ppm TREO, 474ppm MREO from 28m;
  • 29m @ 1,394ppm TREO, 266 ppm MREO from 6m including 3m @ 2,065ppm TREO, 408ppm MREO from 13m; and
  • 18m @ 1,919ppm TREO, 378ppm MREO from 18m including 3m @ 2,015ppm TREO, 359ppm MREO from 21m.

SGQ says the strike of mineralisation has also been extended even further to more than 10km, while providing confidence in the consistency of the mineralisation along this trend.

Grades and thicknesses – and importantly, the high proportion of magnetic rare earths (MREO) such as neodymium and praseodymium (together, NdPr) – are similar to the results from the maiden drilling, pointing to the potential of a continuous high-grade REE deposit.

‘Very large footprint’

“These latest assay results confirm that the near-surface high-grade mineralisation is widespread and consistent in grades and thickness across the 15km2 area tested by drilling to date,” SGQ executive chairman John Prineas says.

“This is a very large footprint and – impressively – the mineralisation remains open in all directions.

“The attractiveness of the Destiny project is also underscored by the high proportion of heavy and magnetic rare earths in the mineralisation – with the magnetic rare earths such as neodymium and praseodymium highly sought-after by the clean energy sector.”


Next exploration push in the works

A completed gravity survey over several prominent magnetic features has also demonstrated the likelihood of a carbonatite intrusive, potentially associated with the REE mineralisation, Prineas says.

“Modelling of the data is in progress and will be fed into our next exploration push,” he says.

“We look forward to planning the next round of drilling at Destiny with a clear focus on establishing a significant deposit of mineralisation at what is shaping as a highly exciting REE discovery in a prime mining province.”
