TMR is first and foremost interested in the graphite sector from the strategic point of view. We are interested in the potential value that specific natural-graphite deposits and their development could have, in the furtherance of the needs and demands of the overall technology supply chain.

The TMR Advanced Graphite Projects Index consists of natural-graphite projects currently underway around the world, which have been formally defined as mineral resources or reserves under the guidelines of a relevant scheme such as NI 43-101 or the JORC Code.

The Index, last updated on July 18, 2014, currently consists of 29 graphite mineral resources, associated with 26 advanced graphite projects21 companies and located in 8 countries, as shown in the table below.

Including the projects on the Index, TMR is currently monitoring a total of 306 graphite projects under development associated with 138 companies in 27 countries.

In addition to the grade and in-situ quantity, the size distribution of graphite flake within a resource is a critical parameter for evaluating its value. In general, the larger the flake size, the more valuable the graphite.

Characterizing a graphite deposit in terms of flake size, however, is something of an arbitrary process; graphite is categorized according to the mesh sieves through which material does or does not pass. There are a wide range of mesh sizes available, and unfortunately there is no standard set of mesh size ranges in use. Furthermore, there is no consistency from one company to another in the use of terms such as "large", "medium" or "fine" to describe categories of flake size (at least one company uses a mesh size range that it describes as "large flake", which other companies categorize as "medium flake", further confusing matters).

This means that unlike, for example, the rare-earths sector, where we can easily compare the relative distribution of individual rare-earth elements between deposits, comparing flake size distributions between projects is not straightforward.

Therefore, instead of a simple comparison chart for flake-size distributions, we present the published data and comments for the projects above as follows:

Flake size distribution
Albany Hydrothermal (non-flake) deposit.
Balama East 2.4% @ +50 mesh (98.2% Cg); 32.7% @ -50/+80 mesh (97.5% Cg); 26.6% @ -80/+140 mesh (97.6% Cg); 16.6% @ -140 mesh (94.0% Cg).
Balama North "High grade large flake graphite".
Balama West 5% @ +300 µm; 42% @ 150-300 µm; 45% @ 75-150 µm; and 8% @ -75 µm.
Bissett Creek 18.0% @ +32 mesh (95.1% Cg); 31.0% @ -32/+50 mesh (95.1% Cg); 28.2% @ -50/+80 mesh (94.5% Cg); 5.0% @ -80/+100 mesh (97.3% Cg); 7.0% @ -100/+150 mesh (98.0% Cg); and 11.0% @ -150 mesh (92.7% Cg).

Other Notes:

  • Over time, the Index will expand as mineral-resource estimates for additional projects are defined.
  • The Index includes advanced graphite projects known to Technology Metals Research, LLC (TMR), based on public-domain information only. Therefore, it is possible that there are other advanced graphite projects currently in development or operation, which are not included in the Index, and / or at the time of the last update, were not known to TMR.
  • Only advanced graphite projects that are fully or partially owned or operated by corporations, or other non-state-run entities, are included in the Index.

Disclosures concerning the above companies: Neither Gareth Hatch nor Jack Lifton is a shareholder of, director of nor a consultant to any of the companies listed in the TMR Advanced Graphite Projects Index (statement current as of July 18, 2014).
