Peako Limited (ASX:PKO) is a mineral explorer primarily focused on our flagship Eastman PGE Project in the East Kimberley region of Western Australia.

Extending over a length of 16.5km with established platinum group element (PGE) mineralisation, the Eastman layered mafic-ultramafic intrusive complex has scope for a significant PGE resource.

Peako’s Eastman Project lies within a large underexplored intrusive complex that the Company considers prospective for a major PGE resource.

The Eastman intrusive complex is located within the Central Zone of the Halls Creek Orogen, where an array of mineralised layered magic-ultramafic intrusive complexes are defined with an established mineral endowment.

Known endowment from layered intrusions in the Halls Creek Orogen includes:

  • Panton – 6.9 Moz PdEq PGE resource
  • Savannah – Ni-Cu 13.5Mt resource @ 1.56% Ni, 0.7% Cu, 0.1% Co
  • Copernicus – Ni-Cu  0.825 Mt @ 1.24% Ni, 0.81% Cu
  • Lamboo PGE – Large PGE discovery

The Eastman Intrusion appears geologically similar to the nearby northerly Panton and Lamboo Intrusions. The three intrusive complexes each have the same ultramafic-mafic rock types and similar intrusion sequencing. Moreover, historical work at all three intrusive complexes has focused on stratiform chromite layers in the ultramafic rocks.

Previous exploration at the Eastman Intrusion, like at the nearby Panton and Lamboo intrusions, focused on the discontinuous stratiform chromitite lenses rather than the wider more extensive PGE-rich stratabound mineralisation that Peako is targeting which has become recognised within the mafic-ultramafic layers of the intrusive complex.
