AuEx Ventures, Inc.: Initial Metallurgical Results for Long Canyon Announced
April 27 2009 - 6:00AM
Marketwired
AuEx Ventures, Inc. ("AuEx" or "Company") (TSX: XAU) is pleased to
announce encouraging recoveries of about 90% of contained gold from
the first two series of bottle roll tests conducted on surface
samples of gold mineralization collected from its 49% owned Long
Canyon project in Elko County, Nevada. Long Canyon is a joint
venture with Fronteer Development Group Inc. who owns 51% and is
operator.
The first series of samples submitted for testing were four grab
samples averaging about 2 kilograms each collected from four
different exposures of gold mineralization in access roads
constructed for drilling. These samples included mineralized Notch
Peak and Pogonip formation limestones selected based on prior road
cut channel sampling and geological mapping. The samples were
submitted to McClelland Metallurgical Laboratories, Inc. of Reno,
Nevada to determine the amenability of Long Canyon gold
mineralization to standard recovery technology by way of bottle
roll testing. The samples were screened at 6mm into two fractions
and the resulting eight samples were subjected to evaluation. Gold
extraction from the plus 6mm fraction samples ranged from 70.4% to
98.4% and gold extraction from the minus 6mm fraction samples
ranged from 90.9% to 97.9%. The overall weighted recovery averaged
93% and reagent consumptions were low.
The second series of four samples submitted for testing were
larger bulk samples averaging about 1.5 tonnes each and were taken
from the same general location as the earlier grab samples. These
samples were also submitted to McClelland Metallurgical
Laboratories for bottle roll evaluation and, in addition, for
column leach testing. Eight bottle roll tests were performed
yielding an average of about 94% recovery of contained gold with
low reagent consumption from material ground to 80% passing 106
micrometers. Eight column leach tests (two from each bulk sample)
are presently underway using material crushed to minus 25
millimeters (1 inch) and four columns (one from each bulk sample)
are underway from material crushed to minus 75 millimeters (3
inch). Results from these column tests should be available by the
end of May.
These initial metallurgical results are encouraging and indicate
that the Long Canyon gold mineralization is likely amenable to
standard extraction techniques including heap leaching. The results
from the ongoing column testing on surface samples are expected to
support this conclusion. Additional metallurgical testing is
planned using samples from deeper in the mineral system which will
be obtained from core drilling scheduled to begin in May. All gold
mineralization identified to date at Long Canyon appears oxidized
and will be confirmed by the ongoing metallurgical program.
