Black Rock Mining Limited (ASX:BKT) is focused on developing its Mahenge Graphite Project, which holds the largest high-grade flake graphite resource in Tanzania – the fourth largest contained graphite resource in the World. Following positive scoping study results released in March 2016, Black Rock released its preliminary feasibility study (PFS) with outstanding results – refer to ASX announcement from 24 April 2017. The PFS will now roll directly into a DFS.
A global Total JORC Resource of 203Mt at Mahenge contains nearly 16Mt of graphite at an average grade of 7.8% TGC (total graphite contained), and includes a high grade proportion of 38Mt at 9.9% TGC.
JORC Ore Reserve of 48.3Mt at 8.7% TGC. Initial 32 year LOM is less than half of the contained graphite.
Excellent large flake distribution, coupled with high purity product: nearly 68% of flakes in the resource are large size and above, with leading concentrate grades of 98% to 99%.
Compelling project metrics: Mahenge is a high margin project. Black Rock Mining has the peer leading absolute percentage of large and jumbo flake sizes, along with sector leading concentrate grades of 98% to 99%, both of which should attract pricing premium in a tight market. On the opex side, bottom quartile LOM cash costs to port are US$382/t, a function of low LOM strip ratio of 0.8:1, and high grade.
Robust capex focus: Lowest pre-production capex of 100ktpa+ production development projects. US$90M delivers phase one production of 83.3ktpa, planned for 2019. Phase two is self-funded from cash flow to add another 83.3ktpa from 2021, for a combined 167ktpa. The project strikes the balance between the scale to attract investment against ability to fund the project.
NPV10 of US$624M (post tax) based on realistic basket pricing of US$1,241/t (NPV10 jumps to US$1.1B using basket price of highest peer). Post tax unlevered IRR is 48.7%. Compares very favourably against peers, especially considering its low pre-production capex profile.
There have been management changes to set the company up for development and production. John de Vries has recently joined as COO and has now been made interim CEO and appointed as an Executive Director, and brings deep experience in mine building and operational excellence, across a number of commodities and continents.
Recently signed a MOU with Japanese conglomerate Meiwa Corporation, graphite product user, and not merely a graphite trading house, which participates in the global lithium-ion battery market.
The large resource with high-grade zones, high proportion of coarse flake and potential to produce exceptionally high purity coarse graphite flake offers flexibility to develop a long life mine that can supply high quality graphite products to customers for decades.
