If they've got similar "upgrading" by contact metamorphism going on, like SYR has, then they should be able to find pockets that match SYR's more prospective defined resources.

The holy grail would be near surface mineralisation with highly weathered silicates but graphite preserving the decontaminated and coarse crystallography resulting after heating by localised intrusions. Flat lying and / or thickening in fold axes would be a triple bonus, but that's probably wishing too much.

IMO, an issue for TONners is that the market has yet to be convinced that they do have some mineralisation that can more than compete with those zones SYR has defined in resource. But in the scheme of things globally the mineralisation is clearly going to be good enough - IMO, it is off-takes that will make it or break it.
