RE: Not near 36,000 Oz any time soon?

RE: Not near 36,000 Oz any time soon?I'll make it easier to you. First excerp of news release:

"The average grade of  mineralisation placed in the above vats, based on the updated pit design, is estimated to exceed 5.5g/t gold.  Based on feasibility and commissioning studies, it is estimated that 50% of the leachable gold will be leached in the first 21 days, with the remaining 50% over the following 50 days.  Expected recovery at this stage is 80%.  The production of gold in any given vat is thus dependent on time and will decrease over time.  Monthly production will show significant variations, particularly depending on the amount of new mineralisation placed in any vat."

All you need to know that there's 46 tonnes leaching in May, ramping up to 57 t in next months. 57 tonnes contain 8000 oz gold that is leached in 71/30 months. -> 3500 oz per month. To keep up this rate you need to replace 24 tonnes ore in month (on average). There's not much to replace in June since ore is still new, but in July they are already putting 27 tonnes of new material in.

Production on spec ~42000 oz/a. Do not worry.
