Black Rock Signs Third Offtake for Mahenge Graphite

“This offtake agreement is significant as having effectively sold out modules 1 and 2,” said CEO John de Vries.

Black Rock Mining (ASX:BKT) has signed a third offtake agreement for natural flake graphite from its Mahenge mine in Tanzania, this time with Chinese trading house Taihe Soar.

The agreement, announced on Monday (January 7), is set to last three years and will see Black Rock supply up to 37,500 tonnes of sized graphite concentrate in the first year, up to 80,000 tonnes in the second year and up to 100,000 tonnes by the third year.

Black Rock’s other offtake agreements are with Qingdao Fujin Graphite Company, signed in October 2018, and Heilongjiang Bohao Graphite, also signed in October 2018. The combined material allocated to all three companies accounts for approximately 85 percent of Mahenge’s proposed 240,000-tonne annual production rate by the third year.

“This offtake agreement is significant as having effectively sold out modules 1 and 2, clearly demonstrates that strong market demand exists for Mahenge’s unique premium and ultra products,” Black Rock CEO John de Vries said in a statement.

He added, “[t]his offtake would not have been possible, without access to concentrate from Black Rock’s study staged pilot plant, the largest in the sector. The pilot plant has been fundamental to the success of our marketing strategy.”

The company made steady progress on Mahenge through 2018, including pilot plant production that saw an average grade of 99.3-percent graphite concentrate using only flotation methods.

Later in the year, Black Rock released a definitive feasibility study for Mahenge that indicates a 32-year mine life, an ore reserve of 70 million tonnes at 8.5-percent total graphitic carbon (TGC) and resources of 212 million tonnes at 7.8 percent TGC.

Pricing for the offtake agreement with Taihe Soar has not yet been determined, but will be established through a formal agreement entered into within a year of the offtake’s execution.

Going forward, Black Rock is working to optimize its mine plan to “compress” its development schedule and increase production by adding a fourth self-funding module.

Graphite Metallurgical Test Work Update


  • Bulk sample of Springdale graphite concentrate estimated to be completed in Q2 2021.
  • Concentrate material will then be sent to Germany to test its amenability for the production of battery anode material suitable for use in EVs.
  • Final test results expected in Q3 2021.

Comet Resources Ltd (ASX:CRL) is pleased provide an update on ongoing test work on natural flake graphite from its Springdale Graphite Project (Springdale) located in Western Australia. Both excellent grade and recoveries were achieved on initial tests, leading to commencement of work to produce a bulk sample for further testing. Importantly, the graphite concentrates previously produced demonstrated a unique and potentially very valuable characteristic in its small size distribution, with two-thirds of the product passing the 38 µm size fraction screen. Generally, this small size fraction of graphite is a by-product of processing of larger flake fractions, which produces smaller size graphite, but in doing so also damages the smaller flake material in the process, reducing their performance and value. Deposits that contain high quality ultra-fine graphite are uncommon and are potentially suitable for supplying the expanding battery anode market, which continues to grow as the sales of electric vehicles (EVs) increase. Graphite suitable for battery anode production also achieves premium pricing in graphite markets, making it a highly sought-after product.
