TRANSCRIPT
• Mineralised ultramafic rocks with high grade gossans over a 40 km belt "
• 3 priority targets:!– Red Hill: lmpact discovery of
30 m thick high grade PGE-Cu-Ni mineralisation!
– Platinum Springs: previous drill intercept of 2 m at 10.9 g/t Pt, 23.6 g/t Pd, 4.5% Cu, 6.1% Ni
– Moorkaie: Exceptional rock chip samples eg 6.8 g/t Pt, 28 g/t Pd, 9% Cu, 2.6% Ni!
!
Highest platinum grades in Australia
Moorkaie!
Platinum Springs!
Red Hill!
• Early 1900’s: Red Hill Mine
• About 500 t was mined with face grades of: – 2 to 4% copper – 2 to 3% nickel – 5 to 41 g/t plaBnum – 22 to 70 g/t silver
• 1969: Two drill holes by CRA but in wrong direcBon
• 2014: Significant soil and rock chip results
Emerging Discovery at Red Hill"
Eagle Deposit, USA: 5Mt at 3.7%Ni and 3%Cu"
Sold to Lundin Mining by Rio Tinto for US$325 million

Size of Eagle Intrusion
Mineralised zone
Red Hill: PotenTal"• Hundreds of
metres of untested strike extent
• Untested EM anomaly
• Many strike
kilometres of untested targets

6500 t at 6 g/t Au, 150 g/t Ag, 2% Cu, 15% Zn & 7% Pb
• Poorly explored: 66 drill holes for an average depth of 53 metres.
• Previous exploraBon focus along 250 m strike at Commonwealth
• Acquired in March 2013 as one licence with 4 km of strike potenBal
• Silurian VMS Deposit • 17.7 Mt at 1.4 g/t gold, 80 g/t silver, 1.7% copper, 9.9% zinc, 3.8% lead for 7.1 million oz gold eq.
• 3.5 Moz gold equivalent underground resource and reserve
• MulBple lenses down to at least 630 m depth
