Electro-magnetic targets reveal a suite of mineralised settings at Block 3

Nimy Resources (ASX:NIM) is pleased to advise that drilling at Block 3 within its Mons project in WA has returned intersections of elevated copper, gold, silver mineralisation in massive sulphides plus high-grade gallium and rare earth oxide mineralisation.

A gradient array induced polarisation (GAIP) survey is planned over the Block 3 Prospect targeting copper, gold, and silver hosted by sulphide mineralisation.

Mineralisation

  • Drilling encountered intercollated suites of felsic, mafic and ultramafic derived rocks.
  • Note: the distance between Block 3 West and Block 3 East is two kilometres. No exploration of any type has been completed in this area by previous companies or Nimy. The aeromagnetics indicates a total strike length of three kilometres.
Block 3 West
  • Massive and disseminated sulphides with elevated copper (0.20%), silver (2.2g/t) and sulphur (13%) values hosted by mafic rocks highlighting
  • potential for VMS mineralisation. Felsic rocks anomalous in rare earth oxides up to 0.58%, with magnetic rare earths up to 30% of total rare earth oxides.
Block 3 East
  • Copper, rare-earth oxides and high-grade gallium trioxide (up to 495ppm) in ultramafic rocks (MgO to 28%) at Block 3 East.

Greenstone Belt

  • Block 3 is 14.2kms south of the Masson copper-nickel sulphide discovery, Nimy has now encountered mineralisation extending 53.5kms along strike of the estimated 80km greenstone length.
  • Full geological and structural interpretation of the newly discovered greenstone belt is underway.

Next Steps

  • Follow-up exploration strategies are planned:
    • At Block 3, DHEM survey of NRRC0103 to test for EM conductors which will continue the massive sulphide trend south, south-west of the drillholes.
    • Conduct a gradient array induced polarisation (GAIP) survey to detect disseminated sulphides down to 150m depth and conductive trends to around 50m depth, which consists of two 1km x 1.5km grids that extend across the Block 3 area taking in the east and west drill lines.
    • Downhole EM and extend the FLEM survey area at the Masson Prospect discovery (copper, nickel, cobalt, and PGE’s) to identify high-grade zones. Full structural and geological interpretation of identified zones leading to new targets – including a focus on gold potential.
    • EM strategy at Block 1 and Vera’s Gossan Prospects (copper, nickel, cobalt, and PGE’s)
    • Investigating the potential of identified rare earth and gallium mineralisation.

Nimy Executive Director Luke Hampson said:

The drill campaign at Block 3 has provided further evidence of the significant potential within the newly discovered greenstone belt at Mons. Nimy has now located and drilled two prospects containing massive sulphides within a 3004km² holding with several more targets pending exploration. The mineralisation differs to that at the Masson Prospect discovery some 14kms north of Block 3, (see ASX release dated March 12, 2024).

The massive sulphides at Block 3 West are carrying elevated levels of copper, gold and silver. Substantial rare earth oxide mineralisation is located above and below the mafic rocks containing massive sulphides. An IP survey is now planned to track the sulphide trend along strike in search of higher grade copper, gold, and silver.

Extremely high levels of gallium and elevated copper in oxide 2kms along strike at Block 3 East highlight a potential VMS discovery.

Gallium is often associated with copper, lead, and zinc mineralisation. Gallium is accompanied by anomalous levels of rare earth oxides. Gallium trioxide values above 100ppm are considered high grade and two substantial intervals of 52m at 105ppm and 72m at 117ppm are present within the Nimy drill holes.

Gallium production is dominated by China, which imposed export restrictions in the second half of 2023 causing an emergence of gallium focused exploration worldwide. A US designated critical metal, gallium has a variety of important uses within the semi- conductor space. Given the high-grade large intervals of gallium Nimy will investigate the stand-alone commercial value of gallium, along with its role as a base metal pathfinder”.
