Inferred Resource would seem to be open at depthMcMaster (TMEx), according the the Press release, has been able to create cross sections:
"This compilation has allowed for the presentation of cross sections and quantifiable data on 8 of the 10 sections that show the surface profiles and the grades of recoverable gold to enable the resource calculation. "
Without the Company's website being available, McMaster's JORC report cannot be seen. How the report treated depth and whether bedrock had been found is not known.
However, we do have some information from our representative shareholder observer, tobinator. His report pointed out that generally, the recoverable grade of gold increased with depth. He also reported that Douglas Lake had been finding that the conglomerate layer was richer than that above. Toby reported that the majority of the pits were about 33 feet (10 meters) in depth, with the deepest being be about 42 feet (12 meters). (Trip Report pp. 10-11)

Significantly, imo, bedrock had not been hit when Toby observed the diggings that apparently forms the basis of the JORC report. Accordingly, the depth of conglomerates, typically the lowest strata, as I understand, would seem not to have been quantified, and the potential recoverable gold in the Matandani prospect could well be understated.
