Hi
@Saltiga62 - as promised, I've collated the grades reported from 28 Dec through to 27 Feb, which from what I can tell is when they started reporting results from using hammer mills (ie starting with the baby 200 k/h).
There have been 9 ANN's in total:
Cascavel: 7 announcements in total
- 35 samples announced in 5 Batches. Samples are random and dispersed across Mestre, Central and Northern zones of Cascavel. Majority of batches were 1 tonnes, and then a few were larger/smaller (as noted in below table).
- Approx 60 panel samples announced in 2 batches. Samples are 2m long continuous along vein throughout the mine up to around 20 kg.
**Interesting note included in the 28 Dec ANN. The reported recovery rate in this announcement was 93%. The sample labelled MSM reported 26.64g/t and was a blend of both stope and development ore. This same batch was processed in a much larger quantity of 100 tonnes through the gravity plant a week earlier on December 22, and achieved a grade of only 2 g/t. Hence this note gives an insight into the potential of the tailings.
Cuca:
35 panel samples, also 2m long continuous along vein throughout the mine up to around 20 kg.
Tailings:
5 one tonne samples (3 at base and 2 vertical channels). Base samples are reported at a depth of 4m, and vertical channels as 0 - 4m. This indicates that the tailing piles are approx 4m high (assuming all piles are stacked to similar heights). Another interesting observation is that the 2 vertical channels have returned similar results to base samples, indicating the gold is evenly disbursed through out the piles.
Grades:
Cascavel: Total = 3,921 g (126 oz) Avg = 36.64 g/t (1.18 oz/t)
Mestre: Total = 1,101 g (35.42 oz) Avg = 31.7 g/t (1.02 oz/t)
Tailings: Total = 46.37 g (1.46 oz) Avg = 9.27 g/t (0.30 oz/t)
I acknowledge these reported samples are still only scratching the surface, however to date the Cascavel samples are random and disbursed across various zones with grades reporting from as low as 0.21 g/t through to 265 g/t. If the average grade of approx 1 oz/t continues and becomes the benchmark - well, we are certainly in for interesting (golden!) times.
Hope everyone had a good weekend.
Hopefully also a good week ahead of us. Personally, I think we'll be getting an ANN early this week, in particular for the 2nd batch of Cuca samples and hopefully for HM3.
