Midway Gold Corp.: Positive Drilling and Metallurgical Results in Spring Valley Update
30 Novembre 2009 - 2:00PM
Marketwired
Midway Gold Corp. ("Midway") (TSX VENTURE: MDW)(NYSE Amex: MDW) is
pleased to announce continued success from third quarter work
reported by Barrick Gold Exploration Inc. ("Barrick") at Midway's
Spring Valley Project, Nevada. Significant intercepts include fire
assays of 339.5 feet of 0.037 opt gold (including 10 feet of 0.485
opt gold) and 156 feet of 0.028 opt gold in SV09-461C. Metallic
screen assays include 220 feet of 0.034 opt gold in SV09-456, 45
feet of 0.058 opt gold including 5 feet of 0.400 opt gold and 110
feet of 0.031 opt gold in SV09-466, and 140 feet of 0.033 opt gold
and 100 feet of 0.021 opt gold in SV09-450. Additional high grade
intercepts include a metallic screen assay of 52.5 feet of 0.889
opt gold including 5 feet of 9.101 opt gold in SV09-451C and a fire
assay of 15.8 feet of 1.731 opt gold including 5 feet of 6.038 opt
gold in SV09-454C.
"We are pleased with the progress Barrick has made this year in
improving the quality of the resource with their program that
tested the grade and distribution of gold, filled internal gaps in
the resource area, and conducted extensive metallurgical tests,"
said Alan Branham, President and CEO of Midway Gold Corp. "These
tests highlight the presence of abundant coarse gold in the Spring
Valley deposit, exhibited in numerous high grade results noted in
this release. Metallurgical tests are examining the effect of
coarse gold to better establish overall grade and determine optimal
gold recovery methods. All of Midway's exploration permits have
been assigned to Barrick so they may test to the north and south of
the resource where there are untested areas with unmistakable
potential for growth. We anticipate an aggressive expansion drill
program in 2010."
Barrick estimates that expenditures through the third quarter
stand at 94% of their US$4,000,000 firm commitment for the year
ending December 31, 2009. Barrick drilled 34 holes in 2009,
totaling 29,002 feet of reverse circulation (RC) drilling and 8,738
feet of core. Fire assay results have been received for all 2009
holes but metallic screen assays are pending on ten holes,
including two of the twin holes. New drill intercepts provided to
Midway by Barrick are summarized in Table 1 below.
Bottle roll and gravity separation tests have been completed and
column leach tests are still underway. Metallurgical testing of
thirteen composite samples continues to give positive results.
Initial Bottle Roll tests are complete and preliminary results were
reported in a previous update (See 24 August 2009 report). Column
Leach tests must run to completion before final conclusions can be
made, but already five of the samples have recovered more gold than
was estimated from the head grade assays.
Results from the gravity testing indicate that substantial
amounts of the gold in the samples could be recovered by simple
gravity methods without fine grinding, but that gravity alone may
not be the optimal processing option. Gravity separation tests
showed gold recoveries in the range of 91% to 50.6% of the
calculated head grade. The majority of gravity recoverable gold was
released with the coarsest grind. Gravity tails were found to be
amenable to leaching of the remaining gold.
Midway and Barrick entered into an agreement on March 9, 2009
for the exploration and development of the Spring Valley property
in Pershing County, Nevada, covering approximately 18.4 square
miles. Under the terms of the agreement, Barrick may earn a 60%
interest in the property by spending US$30,000,000 in work
expenditures by December 31, 2013. Midway is a gold exploration and
development company that currently has four advanced stage gold
resources in Nevada and Washington. Aggressive exploration has
resulted in new discoveries in Nevada. For additional information,

Data reported to Midway by Barrick and disclosed in this press
release has been reviewed for Midway by William Neal, (M.Sc., CPG),

Reverse circulation drilling was conducted by Hard Rock Drilling of
Elko, Nevada. Core drilling was conducted by Boart Longyear of Salt
Lake City, Utah. Drill hole numbers ending with a "C" indicate core
holes. Samples were assayed by ALS-Chemex Labs, in Sparks, Nevada by
30 gram fire assays (FA). Intervals with quartz veining, strong
alteration, visible gold, or anomalous fire assays were re-assayed
using 1000 gram metallic screen assays (MS). Results reported represent
thickness along the trace of the drill hole and do not necessarily
represent true thickness.
