QUESNEL, BC, Nov. 22 /PRNewswire/ - Richfield Ventures Corp.
(TSX.V:RVC) ("Richfield" or the "Company") is pleased to report the
results of preliminary metallurgical testing on samples from the
Blackwater Gold Project approximately 100 km south of Vanderhoof, BC.
Composite samples of drill core from three holes
drilled during 2009, namely BW 43, BW 46 and BW 59, were selected
for initial testing. Samples are of selected sections from the
three drill holes and represent different rock and alteration
types; the samples are of drill core sawed in half lengthwise.
The samples responded well to direct whole ore
cyanidation tests with an average of 92% gold recovery across three
tests at different conditions on each composite (9 tests in
total). Accessory silver was recovered at an average of
47%.
The three composites were also subjected to
flotation testing to produce a bulk sulphide concentrate under
three different grinding and reagent conditions. The samples
also responded well to this test and the best recoveries obtained
under one set of test conditions returned an average for the three
composites of 94% of the gold and silver reporting to the bulk
sulphide concentrate.
The composites were also subjected to direct
gravity concentration, and again the samples responded well with
the three composites averaging 51% gold recovered into a gravity
concentrate.
Drillhole BW 46 is on ground owned 100% by
Richfield. BW 43 and BW 59 are on ground in which Richfield
has earned a 75% interest from Silver Quest Resources Ltd.
Peter Bernier,
CEO, comments, "We are extremely pleased with these preliminary
results which show the tested samples from the Blackwater project
are amenable to high recoveries of gold by conventional
cyanidation. The high recoveries of gold and silver into a
bulk sulphide flotation concentrate and the modest recoveries of
gold by simple gravity concentration are also very encouraging. As
we move forward with additional metallurgical testing these results
provide confidence that an optimized process flow sheet can be
developed using conventional gold ore processing techniques."
The test results reported in this news release
were performed by Metallurgical Division of Inspectorate
Exploration and Mining Services Ltd. in Richmond BC and have been reviewed by
Rob Pease P.Geo., who is a
