VANCOUVER, Feb. 28, 2013 /CNW/ - Kootenay Silver Inc. (TSX VENTURE: KTN.V) is pleased to announce results from preliminary metallurgical testing
conducted by ALS Minerals of Kamloops, British Columbia on the gold
component contained within the diatreme hosted Promontorio Silver
resource. Results from the ALS gold extraction tests show that recovery
of gold from the Promontorio resource is possible using post pressure
oxidation. After pressure oxidation 94.5% of the gold was extracted
from pyrite concentrate.
The economics and capital costs of recovering the gold using pressure
oxidation/cyanidation will require further evaluation. The Company
reports an additional test is now underway to assess the gold recovery
with partial oxidation of the pyrite concentrate of approximately 50%.
States Kootenay President and CEO James McDonald "The results from this
metallurgical testing is a positive development as the Promontorio
resource and mineral system contains a substantial amount of gold that
has yet to be factored into any of our resource calculations. While
additional work is required to assess the economics and capital costs
of oxidation, and what the potential net benefits would be, these
results are a promising first step, as we continue to assess the gold
component at Promontorio."
The testing was conducted on a pyrite concentrate derived from flotation
testing completed at ALS Minerals in Kamloops British Columbia. The
pyrite concentrate had a gold head assay of about 3.0 gpt and about 98%
of the pyrite was oxidized.
The pyrite concentrate was treated through a batch pressure oxidation
testing unit at about 200 degrees Celsius and a pressure of 2000 kPa
for 2 hours. Post oxidation the residue was further treated through a
standard bottle roll cyanidation test. After 48 hours of direct
cyanidation leaching 94.5 % of the gold contained in the pressure
oxidation residue was leached into the solution phase. This preliminary
test indicates that the gold in the pyrite concentrate can be
effectively recovered through post pressure oxidation treatment.
The Company reiterates it is important to note that the economics and
capital costs of recovering the gold contained within the Promontorio
Silver Project using pressure oxidation/cyanidation will require
further evaluation and assessment, which is currently underway on
