Can they mine enough ore? Always been a question.
Using aprogersons numbers and the October presentation on the Caracal website.
Plant 1
- Oct presentation = 10515oz full capacity. Assuming half this as 1 not 2 rock crushers = 5257oz a year = 438 oz a month.
- Aprogerson : 10000t ore x 1.7g/t x 80%recovery / 31.1 = 447oz
- The numbers tie together nicely
- plant capacity = 500t/day… 10000t =20 days
- assuming full capacity for a month = 15000t and 657oz a month
Plant 3
- Oct presentation = 2343oz a year = 195oz a month
- Aprogerson 35kt x 0.93g/t x 53% recovery / 31.1 = 554oz for the 3 month cook time so 554oz a quarter or 185oz/month
- ore needed = 35kt
Ore required
For 437+195= 632oz a month they need 3x10,000 +35,000= 65,000t of ore in a quarter
For 657+195= 852oz a month they need 3x15000+35000= 80,000t of ore in a quarter
In Q3 they mined 64,639t ore. So (in theory) they can mine enough ore for 632oz.
And in previous quarters they have mined near 45,000t ore (no HL - so high grade underground, assuming the low grade comes from a digger and too soil at the top of the hill - ie not underground)
To my mind they can mine and process enough ore for 650oz. Whether they can mine enough for more than this I’m still not sure (depends if the low grade stuff is from strip mining).
So I still do not understand why the gold sold a mi th is half the 650oz number!!
