I beg to differ with you but Dynacor, to my knowledge has done no drilling.
From the eResearch Report I quote "In 2001 Dynacor drove drifts into the Principal and Carnero Veins to define and bulk sample the ore shoots. Dynacor believes using drifts for these structures is more efficient and cost effective rather than diamond drilling and the increased amount of information acquired is much more useful, offering a 3D view, access and better sampling.
More over, a complete detailed mapping of roofs of the drafts has helped understand structural complexities, source and controls of the mineralization. ALL INDICATIONS are that this is a HIGH GRADE GOLD SYSTEM"
Production cash costs were expected to be $260 per oz and recovery rates expected to be 94.5 %
