why cdu has to be a lt investment, page-85

it doesn't matter that they chose the best stuff.
If they can show the grade returned was substantially higher than either of both of the last two jorc's, in that same location, that would be confidence building, provided the sample was of comparable size to the block sizes in the models.
It would be better than just leaving it to speculation.

the trouble with waiting for mining is.. without the same sort of comparison, no-one has any idea how much bonanza there is. It would help their cause to show the market.

They could mine for years without disclosing a model versus actual reconciliation like this.
