Its worth Re-Reading Ann 31st October 2018. Taking into account, we are about to begin commercial processing the level 7 Metstre Vein .
Quote today's AnnI am looking forward to seeing if we can increase gold output in the near term as we have now commenced the processing of stoping ore from the Level 7 Mestre vein.
Extracts from CIL Tests tailing & Mestre ore -Forget tailings component for the time being even though their great, focus on what independent processing of the menstre vein achieved.
Quote-An independent third party ball mill & CIL testprocessed 8.94t of our underground Mestre ore and 22.11t of tailings and returned an average grade of 28.75 g/t Au and 6.143 g/t Au respectively. • The extremely high grade resultsgo a long way to show Cascavel is a potentially rich and large gold system which has so far not performed to its true potential. • When we ran the same test through our own gravity only Hammer Mill 3 and Gekko circuit using similar material from Mestre and tailings, we recovered only 8.75 g/t Au and 2.11 g/t Au respectively – pointing to gold recoveries of less than 40%.
Figure 1. 258 grams of gold recovered from 3rd party ball mill & CIL processing of 8.94t of Cascavel u/g feed averaging 28.75 g/t.
To achieve up to 95% recovery a regrind ball mill and flash floatation circuit is recommended by Gell Street Mining for a cost of A$200,000 - $300,000. We received similar third party advice from Mr Rob Riggir also of Innovative Metallurgical Designs and Management, prior to Gell Street Mining’s visit.
Clearly this is integral moving forward -Plant modifications pending -targeting improved recovery & supplying feed from the Mentre level 7 zone-that just happens to be what was sent for third party analysis. Lots of info here is the link-
