TMR Advanced Graphite Projects Index
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 September 22, 2015, currently consists of 36 graphite mineral resources, associated with 33 advanced graphite projects, 25 companies and located in 10 countries, as shown in the table below.
Including the projects on the Index, TMR is currently monitoring a total of 331 graphite projects under development associated with 159 companies in 31 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:
|Project||Flake size distribution|
