Tanzania – Armadale Capital has signed the drilling contract with CoreworthyDrilling (T), an established Tanzanian based drilling company. Mobilisation of the reverse circulation drill rig has commenced and drilling is anticipated to begin imminently.
The exploration programme for 2017 is focused on upgrading the size of the JORC compliant resource as well as upgrading the resource category so that a significant portion of it moves into the indicated category. The maiden JORC resource estimate for the project is currently 40.9 Mt at 9.41% total graphitic content (TGC).
Areas of near surface higher grade mineralisation have been identified for closer spaced drilling. Initial drilling will be RC with selected areas in-filled with diamond drilling to provide samples for more detailed metallurgical test work.
“Our 2017 exploration programme has now commenced in earnest with the mobilisation of the drill rig and commencement of bulk sampling on site. Although delayed somewhat by an extended rainy season, I am confident that we remain on target to increase our total resource tonnes and also move a substantial portion of our maiden JORC resource into the higher confidence indicated category to enable a prefeasibility study to commence before the end of the year,” says Armadale Capital director Nick Johansen.
In tandem with Armdale Capital’s drilling activities, test work will continue including the production of samples of graphite concentrates for the expandable graphite market and the lithium ion battery market, together with the traditional graphite markets.
Test work conducted to date has delivered highly positive results, with purity of above 99.95% being achieved for size fractions between 106 µm and 500µm, which are typically used for the production of spherical graphite.
“These consistently encouraging results underpin the project’s ability to produce high quality graphite concentrates, which should be suitable for a number of commercial applications.”
