In general, the flotation performance of these composites was v ery good, with high silver
recoveries achieved using Potassium Amyl Xanthate (PAX) as the primary mineral collector. Silver

reported using this simple approach. Silver recovery appeared to be relatively insensitive to pulp pH
although finer grinds and the addition of a secondary collector appeared to give marginal increases
in metallurgical performance for the transition composite.

The oxide composite also responded well to standard sulphide flotation conditions with silver
recoveries in the 90% range. Maximum recoveries were achieved us i n g n i t r o g e n g a s f o r o x i d e
composite flotation, although this slight improvement appears t o have been achieved primarily as
a result of higher concentrate mass pull.
These initial scoping tests show that silver minerals can be ef ficiently concentrated using relatively
simple froth flotation conditions. Flotation concentrates conta ining 2,500 – 3,000 g/t silver were
produced without using a cleaner flotation stage.
Bottle Roll Leach Testing
Four metallurgical composites of oxide, transition and sulphide mineralization were prepared for
cyanide leaching test work as summarized in Table 3. The bottle roll test work program comprised
of a battery of 33 individual scoping tests, each running for 72 hours and using a variety of
conditions (grind sizes, cyanide solution strength, oxygen leve ls, and temperatures) to assist begin
definition of the metallurgical characterization of Silver Sand mineralization.
