Armadale Capital Plc upgraded inferred resources at its Mahenge Liandu graphite project in Tanzania to the indicated category, and more than 75% of the total resource is now in the higher-confidence classification.
The total now comprises 51.1 million tonnes at 9.3% total graphitic carbon, or TGC, including indicated resources of 38.7 million tonnes at 9.3% TGC and 12.4 million tonnes at 9.1% TGC, using a 3.5% TGC cutoff.
The upgrade represents a 25% increase from the previous 40.9 million tonnes of inferred resource at 9.41% TGC, the company said Feb. 7.
The deposit remains open to the north, south and downdip, indicating significant potential to increase the resource further. The company is planning a diamond drilling program for later in 2018.
"The results of this, together with the expanded and upgraded resource, will feed into the ongoing scoping study, which is targeted for completion by the end of the first quarter and will give further clarity on the commercial potential of Mahenge Liandu," said Nick Johansen, an Armadale director.
According to the company, test work to date has confirmed that premium-quality, high-purity concentrates can be produced using a conventional flotation circuit.
