Gold-silver potential

SGS Peru has been appointed to undertake metallurgical test
work from the recently completed 15,000m drilling programme
at Antilles Gold Ltd’s La Demajagua gold-silver deposit in south-
west Cuba.
The aim of the test work will be to establish preliminary
concentrate mass recoveries and upgrade factors, along with
indicative process design criteria.
SGS will also undertake oxidation tests using the flotation
concentrate for both the pressure oxidation process and
Glencore Technology’s Albion process to determine likely gold
and silver recoveries from cyanide leach after oxidation, for an
initial project evaluation should the company decide to process
the concentrate to produce higher value gold doré.
A concentrate sample will also be provided to a pressure
oxidation facility in Russia permitted to import and process
