@Dave RNS 15-Oct-20 gives Operations Update with routemap to first production ...
"The Company is focused on producing first gold and silver from the MJ operation this year and has continued to make good progress as it develops this mineral rich asset, where work in progress consists of:
· Transportation of bulk material from the high altitude site
· Assaying material and commencement of a leach testing programme
· Further evaluation of long-term production options
· Processing first gold and silver via a gravity separation circuit
......... Great Western's immediate aim is to prove up the concept of recovery from spoil heaps in 2020 by producing first gold and silver. "
> current approval for MJ licence allows for removal of up to 900t of spoil heap material .... "and will deliver 25 tonnes during October."
> Recent "fire assay of crushed and pulverised sub-samples, reporting 2.28 grams/tonne gold plus 658 grams/tonne silver "
> Recent lab tests showed "achieved 87% gold recovery and 46% silver recovery from a 48 hour leaching process.
"Great Western Chairman Brian Hall commented: "We are on track to produce our first precious metals from the spoil heaps at Mineral Jackpot and to prove our concept. Until the recent completion of laboratory testing, we could not be sure that gravity separation would be a viable option for producing gold and silver from Mineral Jackpot, but I am now pleased to report that we believe it is. In the immediate term, therefore, we expect to produce gold and silver through gravity separation while for the longer term we will develop an optimised leaching facility, based on the data acquired from the ongoing extensive testing programme, to achieve a higher long-term recovery rate. We will provide further updates as appropriate."
