Boy, Chuca, that Tintina NR reads like a lot of dry scientific journal reports I used to have to pore over in University! I guess such thorough reporting is necessary with innovative methodologies like the Ateba Mines' "deflocculant" (FYI, for a brief explanation of this exciting new sample processing see this link: Message 8991261 ).
============
This deflocculant process may be a Godsend for some AB mineral exploration companies.
-WRT the TTS news, support for this new methodology, first in testing for diamonds and DIM's, and in Au/ heavy mineral assaying is certainly there:
From the TTS nr of today,
"..Examination of two recently prepared concentrates from two new samples has reported diamond indicator minerals but as yet reported no gold and intentions are to broaden this work in the months to come."
- -
Also from the same NR,
"..The high clay content of the smectitic shales has continued to present challenges to standard sample crushing and pulverization procedures as has their high organic content varying 5 per cent to 11 per cent organic carbon by weight. Due to their often ductile behaviour during crushing, many of the samples have necessarily required longer than normal sessions in the crusher circuit to achieve acceptable disaggregation, occasionally resulting in sample weight losses varying 2 per cent to 10 per cent...
The tests do, however, suggest that repeated sample handling and pulverization of isolated small subsamples may indeed contribute to significant gold losses since assaying of some pulverized as well as unpulverized test charges with known gold content under reported the reconstructed calculated gold grade or reported nil."
and,
"..Although the tests were orientative, results therefrom served to confirm extractability of gold by conventional leaching, following deflocculation, using activated carbon. Of the total of 12 charges tested, only charges which were deflocculated reported gold. Fire assaying carried out by Lakefield of 11 head samples of the material cyanidated reported highly variable results reiterating that considerable nugget effect is associated with routine gold analyses of the shales and suggesting the presence of coarse gold therein."
And lastly,
"..In closing, most of the results from the recent work indicate that subgram overall gold grades from the zones with an apparent enrichment nearer the upper and lower contacts of the Second White Specks formation. Whether these grades will ultimately prove to be economic is as yet unknown although overall grades ranging 0.5 g/t one g/t must be regarded as highly significant given the economic latitude afforded large unconsolidated surface bulk-minable deposits."

This new methodology could be very significant for many players in the ADP, and for many co's in mineral exploration period!

WRT to the ACS release, gotta wait for results I guess!

(You are more of an expert, Chuca!)
