drill core.All i know is that, in my experience, not very many companies show you a visual of the drill core before releasing assays and the ones they showed a few weeks ago looked pretty good (to my untrained eye). also, they got a little more financing shortly after they got those first core samples out of the ground. it seems like they were eager to do some more drilling..... why? I think this will be a make or break moment for mtb and i'm thinking they have something decent.
