I’m a bit behind, haven’t even read todays conversation.
The HL timeframes annoyed me when I first invested and tried to understand the length of a HL cycle. Robbie in an interview stated ‘20,000t - and that’s EVERY MONTH’ (he was talking about plant 3). It seemed to confirm the cycle is 1 month. APG, your numbers tie in with the June presentation, so I am prepared to ignore Robbie’s comment. As you say the recovery factor will go up for a 90day leach, not included in the presentation figures.
One question, APG. If HL (plant 3 +4) is 140,000 tonnes every 3 months, 560,000t a year. Then the remaining tonnage is 364,000t (from the 924,000t figure).
This is 30,000 t a month through plants 1 and 2. But (I think) your numbers stick with half this, 15000 tonnes a month through plants 1 and 2;
‘15tpm x 2.5g/t x 91% / 31.1 = 1,097oz’
Using 15000tpm does give gold production numbers that match the presentation but there seems to be a missing 15000tpm? To balance the 924,000tpm plants 1 and 2 should be processing 30,000tpm?
Knowing me I’ve probably missed something.
