The company’s shares are trading about 8% higher intra-day following the update, at 3.9 cents.
Black Rock despatched large volume samples produced from its initial 90-tonne pilot plant test work in Canada to 22 potential customers.
Initial feedback has been positive, with Black Rock’s recently introduced Ultra Purity-FP™ Flake Graphite, with a minimum purity of 99.0% LOI (Loss-on-Ignition), well received by potential customers.
The company has received confirmation that the 1% or less total ash content offers the ability for specific applications to use this new high-purity flake graphite without the concern of any caustic chemical intervention to reach the 99% LOI purity target.
Black Rock chief executive officer John de Vries said: “We are very pleased with the positive feedback we have received on our graphite concentrate.
“We remain the only graphite developer that can produce a 99%+ concentrate and interestingly this is resulting in more approaches by new potential customers.
“The feedback confirms we have a unique graphite concentrate that will be sought after by a multitude of graphite users for a wide range of applications.”
One of the largest flake graphite resources globally
Black Rock’s 100%-owned Mahenge Graphite Project is one of the largest JORC-compliant flake graphite resources globally, with 211.9 million tonnes at 7.8% TGC (total graphitic carbon) for 16.6 million tonnes of contained graphite.
The company had released an exceptional pre-feasibility study (PFS) for the project, which considered a three-stage construction to deliver up to 250,000 tonnes per annum of 98.5% graphite concentrate for 31 years.
Black Rock is continuing to progress discussions with respect to construction and financing support, off take and agency agreements to advance the Mahenge Graphite Project.
