Lukie1,

The company has already announced 1m tonnes at 8.3%. As for what is in the ground, time will tell. We should find out soon enough. As noted by PDZ an updated resource calculation is now in preparation and is expected to be complete in August.

Lukie1, to me, the recent institutional acquisition of 6m Shares at .91c (not discounted) and recent appointment of Charlie Karelse as Chief Operating Officer indicating the company's intent to mine, suggests that PDZ are sitting on a significant resource. As for how much, my guess would be as good as yours.
I don't think the institutinal investors would have invested as they did unless they were pretty sure that PDZ was sitting on very sizeable Zinc deposit. Anyone want to take a guess as to how much they have?

Given the price of Zinc and the company's small current market cap of roughly $45m (fully diluted) I predict that it won't be long before the SP exceeds the recent $1.30 highs witnessed in June.
