Black Rock Mining Limited is an Australian based company listed on the Australian Securities Exchange (ASX:BKT).  The Company has an 84% interest in the world-class Mahenge Graphite Project (Mahenge) located in Tanzania.  Mahenge has a JORC compliant Mineral Resource Estimate of 213m tonnes at 7.8% TGC.  It also has Ore Reserves of 70m tonnes at 8.5% TGC. The Ore Reserves support a mine life of up to 350k tonnes of graphite per annum for a reserve life of 16 years.  Since the release of the Mineral Resource Estimate, the Company confirms that it is not aware of any new information or data that materially affects the Mineral Resource Estimate.   

In October 2018, the Company released a Definitive Feasibility Study (DFS) for Mahenge, which was based on strong customer demand. This was enhanced (eDFS) in July 2019 (ASX Announcement 25 July 2019).  Black Rock has obtained all Environmental approvals, Mining Licences and its Resettlement Action Plan with clear title to the eDFS project area. 

In June 2020, the Company announced a Strategic Alliance with POSCO Group for the development of Mahenge.  This included an equity investment of US$7.5M, signed in February 2021, followed by an offtake agreement, with a US$10M prepayment facility.  In December 2021, Black Rock signed a Framework Agreement with the Government of Tanzania confirming their 16% Free Carried Interest shareholding, agreed to consolidate its Mining Licenses into a Special Mining Licence (SML) and committed to jointly develop Mahenge.  The Company is construction-ready subject to financing and issue of the SML.

Black Rock completed a FEED process (Front End Engineering Design) in September 2022, re-estimating the capital and operating costs for Mahenge as part of the debt financing process.  The FEED work confirmed Mahenge as a robust project with attractive returns.  Key project metrics comprise:

  • Tier 1 Scale: Mahenge has a resource of over 200mt and the 2nd largest graphite reserve globally
  • Modular development approach: Module 1 Capex of US$182m*
  • 1st quartile on the global cost curve: Adjusted C1 Cash cost of US$359/t**
  • Attractive projected returns: Unlevered IRR post-tax, post free carry of 36%***
