HUNCH ?MY OWN THOUGHTS ON - - IMPERIAL ? The average gold content of this material was determined by mine staff to be 3.02 grams per tonne. The material was fed into the mill at a rate of approximately 50-100 tonnes per hour over a 2 day period, comprising a maximum of 10 per cent of the total mill feed. Robertson (2001) reports that gold recovery in the milling circuit was good; however, boosting the amount of pyrite pulled off to increase gold recovery in the flotation circuit had an adverse effect on the copper concentrate grade. As a result it was concluded that the Spanish Mountain material was not suitable for blending with the Mount Polley mill feed owing to the fact that the added precious metals credits were more than offset by the reduced copper grade. ----------------------------------------------------------------------------------------------------------------------------
Was it really a
pyrite issue in Imperials - flotation - or more like - graphitic pyrite.
Doesn't Spanish mention the issue of - graphitics - in thier own flotation testing ?
Ahhhh... ha.
Now... can we please see the graphitic + carbon values.
Please and thank you.
This is beyond delay....drills, test pits, pfs, etc....
Shareholders need far more answers...
I'm seeing - carbon black, and perhaps, graphitic grey pyrite.
Now... look at al lthe other cores still in thier core trays...
Pretty consistent - black carbons...
I'm thinking - Imperial's flotation was not set up for - carbons + graphitics.
Who the heck would shun an averaging of - 3.2/gtoone of gold...lol
IMPERIAL DRILLED ALL NEAR SURFACE - - 13m DEPTHS....
This issue is... the more spanush drilled elsewhere... and kept tacking on the
ore tonnage and new grades = it diluted the original hogher gold grams...
Then.. .throw in nuggety or placer effect- much can be lost in translation of
what the real gold gram vlaue really is.... bulk testing is needed in such unique - deposits.
Spanish recently - performed another - 84 test pits...nearly 6 months ago.
Yeah... that kind of - kept in the dark.
