Ann: Grande Cote Mineral Resource and Ore Reserve Update, page-2

It is not clear from this announcement if there has been any new drilling - (extra hand augering or drilling) to increase the ore reserve.   In 5 years (2022) a company tax of 25% will apply at the same time as the mining cut-off grade reduces from 1.3%HM to 1.%HM.
If 1.3% is the current mining cut-off grade then the GCO operation (assuming an even ore grade throughout - which they claim) should be outperforming the nameplate capacity!

The ore reserve states that "There is sufficient record-keeping and reconciliation of the mining and separation
processes. There are no significant changes planned for mining and processing."

Why can't MDL provide this reconciliation (comparing ore mined to the ore reserve of mined blocks) to shareholders?  The second part of the quote
"There are no significant changes planned for mining and processing." could be interpreted that 82% (current production) or thereabouts of nameplate capacity is the best we can expect."
From management announcements, I still do not know or understand how GCO is performing in its quest to reach nameplate capacity or whether the ore reserve grade is inaccurate or the lost 18% of production is going into tailings.

The reporting by management is opaque, we need some clarity!
