AuEx Ventures, Inc.: Initial Column Leach Test Results Announced for Long Canyon
June 11 2009 - 7:00AM
Marketwired
AuEx Ventures, Inc. ("AuEx" or the "Company") (TSX: XAU) is pleased
to announce that gold recoveries averaging as high as 90.1% have
been received from the initial series of column leach tests
performed on four bulk samples of gold mineralization from the
Company's Long Canyon gold deposit in joint venture with Fronteer
Development Group Inc. These results provide continuing support
that gold mineralization at the Long Canyon Venture is readily
amenable to standard heap-leach process technology.
In late 2008, four bulk samples, each weighing approximately 1.5
tons, were obtained from outcrop exposures of gold mineralization
in road-cuts at the Company's Long Canyon gold project and
submitted to McClelland Laboratories, Inc. of Sparks, Nevada for a
series of column leach tests at crush sizes of -25mm (-1 inch) and
-75mm (-3 inch). Gold recovery rates for all of the samples were
rapid and gold extraction was substantially complete within the
first 10 to 15 days of leaching. Gold recoveries for the -75mm feed
size ranged from 84.2% to 96.6% (89.7% average) in approximately 65
days of leaching and rinsing. Column leach gold recoveries for the
-25mm feed size ranged from 85.6% to 96.3% (90.1% average) in
approximately 69 days of leaching and rinsing. Reagent consumption
levels were low and no solution percolation, fines migration,
solution channeling or slumping problems were evident in this
initial phase of column leaching. Cumulative recovery charts for
the column leach tests on the four samples are posted on the
Company's website.
Additional column leach test work is planned during 2009 as part
of the current $14.1 million work program currently underway at
Long Canyon. These new column leach metallurgical tests will be
performed on deeper, sub-surface samples of gold mineralization
obtained from drilling of 17 PQ sized (4.5 inch diameter) core
holes that were completed in May. The results of this work will be
available later in 2009.
