Duketon Mining holds tenure within the highly prospective Duketon Greenstone Belt, north of Laverton in the Eastern Goldfields mineral province.

The belt has been explored for both gold and nickel since the late 1800’s and total discoveries of this belt stand at over 71,000 tonnes of nickel and 8 Million ounces of gold.

Duketon’s tenement package lies along strike and adjacent to Regis Resources’ landholding including the Rosemont, Garden Well and Moolart Well Gold Mines.

Duketon Nickel

The Bulge Ultramafic Complex, a folded and thickened sequence of ultramafic, is host to the Rosie and C2 nickel sulphide resources and the Nariz discovery.

Prior to the South Boulder Mines Ltd / Independence Group NL JV only sporadic exploration for nickel had been completed in the Belt, mainly in the 1960’s and 1970’s.


The Rosie Deposit was discovered in 2006 by IGO-STB JV. Mineralisation is characterised by massive, matrix, breccia and disseminated Ni-Cu-PGE magmatic sulphides and the basal contact of the komatiite ultramafic flow.

JORC 2012 Inferred and Indicated Mineral Resource of 1.94Mt @ 1.7% Ni for 33,000T Ni, 7,760T Cu and 118,000oz Pt+Pd.


Duketon Mining Limited Rosie Nickel Rescourse Table


Discovered in 2006 by IGO-STB JV. The C2 deposit consists of a series of disseminated, blebby and matrix sulphide zones within and proximal to the contacts of the ultramafic complex. Three broad zones of mineralisation have been interpreted. JORC 2012 Mineral Resource estimate is 38,000t Nickel, 2370t Copper and 26,000oz Platinum and Palladium. C2 is open at depth and along strike.

The Nariz Prospect was discovered by Duketon Mining in 2014. The Maiden drillhole intersected 5.65m of massive sulphides at 7.09% Ni, 0.5% Cu and 3.76 g/t Pt+Pd within a broader intersection of 9.22m @ 4.96% Ni, 0.41% Cu and 2.41 g/t Pt+Pd (DKMDD0005)

Further intersections include:

3.73m @ 2.04% Ni, 0.54% Cu, 1.91 g/t Pd+Pt and 1.51m @ 1.01% Ni, 0.11% Cu, 2.65 g/t Pd+Pt (DKMDD006)

2.0m @ 2.1% Ni, 0.4% Cu and 0.7g/t Pt+Pd (DKMDD008)

1.2m @ 1.2% Ni, 0.3% Cu and 0.6g/t Pt+Pd (DKMDD009)


The Somerset Nickel Prospect, located 30km north of Laverton, has been identified for its potential to host nickel sulphide mineralisation. Historical regional spaced aircore drilling across the magnetic high has intersected cumulate textured ultramafic and returned anomalous nickel results. The ultramafic unit extends over approximately 7km with interpreted structural repetition of the ultramafic adding another 3km of prospective contact to explore. Possible embayment features can be seen in the ultramafic unit from the magnetics which are targets for nickel sulphides.

Significant Intersections from historical drilling include;

  • 12m @ 0.77% Ni & 209 ppm Cu inc. 8m @ 0.94% Ni & 359 ppm Cu
  • 10m @ 0.73% Ni & 70 ppm Cu
  • 16m @ 0.62% Ni &145 ppm Cu

XRF results from iron rich drill chips collected in the field include;

  • 5.84% Ni & 1,607 ppm Cu
  • 2.97% Ni & 91 ppm Cu
