Minco Silver Reports Over 97% Silver Recoveries from Initial
Metallurgical Tests at the Fuwan Project
======================================================================
Minco Silver Corporation (the "Company" or "Minco Silver")(TSX: MSV) is
pleased to report that the initial metallurgical testing has been
completed on material representative of the mineralization at the Fuwan
silver project located in Guangdong Province, China. The work was
carried out by Process Research Associates (PRA) of Vancouver and
included options of gravity separation, cyanidation, and flotation. As
a basis for the test work, 400 kilograms of representative material of
the Fuwan deposit was taken from drill core and pulp rejects from the
drill core to form three samples. These included a sample from Zone 1,
a sample from Zone 2, and a composite sample prepared from Zone 1 and 2
samples.
Following a series of "open cycle" tests using different grind sizes
and a variety of reagents, it was found that a simple flow sheet using
conventional flotation, standard reagents, provided encouraging
recoveries. Subsequent "locked cycle" flotation tests on the composite
sample have resulted in overall recoveries for silver from lead and
zinc concentrates of 97.9%. In addition, good results were obtained for
other contained metals with recoveries of 97.9% for zinc, 94.0% for
lead, and 77.4% for gold.
Of particular note is the substantial upgrading in silver that occurred
in the lead concentrate. For the composite sample, the head grade of
244.5 g/t silver increased to a concentrate grade of 9,325.1 g/t
silver. Flotation tests for the individual samples (Zones 1 & 2)
provided similar results.
Results of the Locked Cycle Test are as follows:

Other results completed by PRA during the metallurgical testing
included a determination of the Bond ball-mill index. Based on a closed
screen size of 200 microns, this was calculated to be 17.8kWh/tonne.
The Fuwan ore is therefore judged to be of average hardness.
The results of the PRA metallurgical work will be used for the
preliminary plant design in the Preliminary Economic Assessment
currently being conducted by SRK Consultants.
Minco Silver Chairman and CEO Dr. Ken Cai commented: "We are very
pleased with the recoveries from this round of testing at the Fuwan
project. These results indicate that we can expect excellent silver
recoveries using conventional flotation with standard, readily
available reagents. We can also expect substantial value from the
other contained metals that will be recovered from a deposit located so
close to existing infrastructure and domestic markets."

Dwayne Melrose, P. Geo, Vice President Exploration for Minco Silver and
Qualified Person responsible for verification and quality assurance of
the company's exploration data and analytical results.
