The feasibility talks about them re-logging and sampling of the historical core samples.
"Between and August and November of 2011, select holes and intervals of historic
drill core were re-logged to test and formulate a consistent geological and structural
interpretation, to provide input for the construction of a 3D model, and to provide a
robust framework for future work."
They also state: "During this program, the rejects of 5,359 historic samples were re-assayed
at Acme Analytical Laboratories Ltd. (AcmeLabs) in Vancouver, BC."
This was awhile ago, but they might have cores to do some of that work they are supposedly doing to improve the recoveries.
