Ajana Project

The Ajana Project is located in Northampton, Western Australia, a proven and established mining province for zinc, lead, silver and graphite.

The project is situated within the prospective historic mining centre of Ajana. The tenements, E66/89 and E66/94, and E66/100 (under application) are located 130kms north of Geraldton and on the North West Coastal Highway.

Highlights of the Ajana Project include:

• 2012 JORC Pb Resource at Mary Springs
• The global Indicated and Inferred Resource estimate is 390,000 tonnes grading at 6.5% Pb.
• Four Regional Graphite Prospects
• Walcott (reprocessed historic EM targets)
• Mary Springs (rock chip/Mullock samples)
• Geraldine, and
• Warrianno
• Jumbo flake (>300 microns)
• Rock chips up to 42%TGC
• High grade metamorphism with hydrothermal alteration
• Graphite schist within a Proterozoic Gneiss

The Ajana area is dominated by the Proterozoic gneiss with conformable lenses of meta-sediment, pelitic gneiss, meta-quartzite, mafic gneiss and graphitic schist known as the Northampton Metamorphic Complex. This gneissic geological environment, typically hosts high grade graphite deposits in Western Australia.

The Northampton Complex is intersected by a closely spaced swarm of dolerite dykes striking north northeast associated with shear zones and parallel to the fold axes. All the lead-silver and copper mines in the Northampton Complex appear to be related to the same north northeast trending fault system that has controlled the intrusion of dolerites.

Mary Springs Lead Resource 

The updated Mineral Resource has been reported at a cut-off grade of 1%Pb, a summary of the estimate is shown in Table 1 below.

Category Indicated Inferred Total
  BCM Tonnes % Pb BCM Tonnes % Pb BCM Tonnes % Pb
+ 1% Pb 80,000 240,000 6.6 50,000 150,000 6.2 130,000 390,000 6.5

The strings in the Block Model were created from cross sectional interpretation and were wireframed into 5 solids (designated lodes 100, 200, 300, 400 and 500) as shown in Figure 1. Zones of Pb-Zn-Cu-Ag rich mineralisation have been intersected in recent drilling but were not included in modelling the resource, see Table 1. Further drilling may enable the zinc, copper and silver bearing zones to be modelled as part of a future resource.

Ajana Graphite Project

The initial small drilling program showed a graphitic rich clay horizon (surface to 25m) and a graphitic schist below that with graphitic grades increasing with depth.
Graphite mineralisation intersected at Mary Springs North included:

• 30m @ 2.3% TGC from surface (up to 4.1% TGC)
• 5m @ 5.5% TGC
• 3m @ 4.8% TGC
• Shallow mineralisation similar to previously tested samples at Mary Springs, 1.5km to the south:
• Average floatation concentration value of 94.1% TGC
• Spherical graphite purified to 99.7% TGC


Research work carried out has shown that:

  • Pristine sheets of graphene could be produced, particularly, single layers;
  • The graphene has shown to be uniform and defect free;
  • Ajana graphite is said to be of very high quality resembling a highly ordered pyrolytic graphite (HOPG).
