Sinclair Nickel Project

Sinclair Nickel Project tenements within the Agnew-Wiluna Greenstone Belt

The Sinclair Nickel Project is located in the southern portion of the Agnew-Wiluna Greenstone belt in Western Australia, one of the world’s premier nickel sulphide provinces.

Talisman acquired Sinclair from Glencore subsidiary Xstrata Nickel Australasia Operations in October 2014 and the project represents a potential development opportunity under the right nickel market conditions.

The Sinclair deposit was discovered in 2005 and a mine was developed and brought into production in 2008 and operated successfully until August 2013 before being placed on care and maintenance.

In the five years it operated, the mine produced 38,500 tonnes of nickel from ore with an average head grade of 2.44% Ni.

Sinclair is an exceptional nickel sulphide exploration opportunity in a fertile belt. Target areas exist throughout the tenement package including:

  • Potential immediate extensions of the Sinclair deposit itself;
  • Near-mine targets within close proximity of the existing mine infrastructure; and
  • A number of exploration prospects within a 30km radius of the mine.

In 2018 Talisman established a JORC 2012 Indicated and Inferred Mineral Resource of 16,200t of contained nickel. A summary of the Mineral Resource is contained Table 1.

JORC Category – Indicated
Grade Cut-Off (Ni %) Tonnage Grade (Ni %) Contained Ni (t)
0.5 370,000 2.0 7,400
1.0 350,000 2.1 7,300
1.5 250,000 2.4 6,000
2.0 140,000 2.9 4,100

 

JORC Category – Inferred
Grade Cut-Off (Ni %) Tonnage Grade (Ni %) Contained Ni (t)
0.5 1,080,000 1.6 17,200
1.0 910,000 1.7 15,900
1.5 460,000 2.2 10,200
2.0 180,000 2.9 5,400

This Mineral Resource has further upside from an additional Exploration Target and multiple EM plates which support the potential continuity of mineralisation down-plunge and along strike.

The Sinclair Nickel Project includes a fully developed underground mine and extensive high-quality surface infrastructure.

This infrastructure includes:

  • A 350ktpa concentrator
  • Open pit, decline and underground mine
  • 200-person accommodation village
  • Administration buildings and fully equipped stores warehouse
  • Core yard and exploration office
  • Mining contractor facilities
  • Reverse osmosis plant and waste water treatment plant
