OK !!! What we actually know for sure
6749 oz produced to the end of Aug
as of Sept 21st a further
1700 oz was poured, with 9 days left in the month to end of 1/4
processing is at 600 tonnes per day processed,
with a call grade of 10.9 gpt.
= 8449 oz poured for sure,
plus
600 tonnes x 9 days = a further 5400 tonnes likely processed
5400 tonnes x 10.9 gpt = 58860 grams
58860 grams / 32 = a further 1839 oz produced in those nine days to end of 1/4
Total likely oz in this 1/4 = 10,288 + gold in circuit
A full high grade 1/4 at forecast should produce
12,500 - 15000 oz from 32,500 tonnes
We will be around 33,800 tonnes at end of 1/4 right up there.
Coyote Plant in operation with Tanami Gold had 1861 oz gold in circuit in the Coyote plant, as of end of 2012, you can see this in 2013 End of year accounts around page 43.
10,288 + 1861 gold in circuit = 12149 oz "the upper end of forecast" for oz produced,
plus this includes 12,000+ tonnes of low to medium grade ore throughput.
Everything we have been told and know is telling us we are on target at the upper end, even with many tonnes of low grade ore being processed and no further news.
Grade this 1/4
12149 oz x 31 = 376619 grams
376619 grams divided by 38,800 tonnes = 9.706 gpt
at least 30% of the ore was lower grade averaging 5.7gpt
replace that with 10.9 gpt and
12,000 low grade tonnes x the difference in grade 5.3 gpt = 62400 grams
62400 grams / 32 = another 1950 oz that would have been produced in a full grade 1/4
for a total of 14099 oz exceeding upper forecast.
A full high grade 1/4 at forecast should produce
12,500 - 15000 oz from 32,500 tonnes
