Merc Releases Further Gold Intersections at BIF Island Zone
15 Juni 2010 - 2:30PM
Marketwired Canada
Merc International Minerals Inc. ("Merc") (TSX VENTURE:MRK) is pleased to report
results today for fourteen new drill holes from its 2010 Winter Drill Program on
its Damoti Lake Gold Project in the Northwest Territories. Drill results include
the final eleven holes at the BIF Island Zone, and three holes at the Granite
Showing located between the BIF Island and Horseshoe Zones.
Sectional drilling at the BIF Island Zone has confirmed a strong core of gold
mineralization that conforms to the general plunge of the fold structure. The
limits and expansion opportunities of this mineralized zone will be further
evaluated in the coming months. The eleven BIF Island holes represent the
remaining holes drilled at this location over the current program, and include
the following highlights: 4.89 grams per tonne gold over 7.55 meters, including
15.10 grams per tonne gold over 1.50 meters in hole D10-402, and 12.97 grams per
tonne gold over 1.50 meters, including 26.30 grams per tonne gold over 0.50
meters in D10-403B. Several reconnaissance holes, aided by geophysical data,
were laid out away from known mineralization in order to explore for extensions
along strike and down plunge. Drilling of these sections was successful in
helping to validate a new geological model for gold mineralization, one that
will evolve as Merc continues to explore Damoti's fertile stratigraphy.
"We are extremely pleased with our drilling results to date. Since initiating
our first program in July 2009, Merc has repeatedly intersected both high-grade
gold mineralization and broader zones of significant values, all within the
near-surface environment. Exciting opportunities exist for additional
discoveries at depth, along strike, and in similar structures lateral to those
hosting known mineralization. All remain to be tested. If successful, these
ongoing initiatives will add significant value to the entire Damoti Lake Gold
Project," said Dr. Michael Byron, President and CEO of Merc.

D10-424 BIF Island Extension - iron formation intersected,

----------------------------------------------------------------------------
(i) Lengths are reported as core lengths. True widths are not known at this
time.
The BIF Island Zone, an area of folded iron formation similar to the Horseshoe
Zone, is located 3.5 kilometers northeast along strike from the Horseshoe Zone.
Drilling at BIF commenced on March 19, 2010 (March 24, 2010 news release) as
part of a 10,000 meter program to extend known mineralization at BIF, as well as
within the Horseshoe North and Red Mountain Zones, and to test other targets
identified by the recently completed ground geophysical surveys (March 4, 2010
news release). Initial drill results were reported in a May 08, 2010 news
release in which holes intersected broad zones of gold mineralization containing
high-grade cores. For additional information on drill hole locations and Merc's
drill program please visit Merc's website www.mercinternational.ca.
Three holes were drilled at the Granite showing to test mineralized areas of
iron formation 1,500 metres northeast of the Horseshoe Zone. Although the holes
were drilled below several surface showings with associated favorable
geophysical responses, they failed to return significant mineralization.
Quality Control
Merc International Minerals Inc. has implemented a quality-control program to
ensure best practice in the sampling and analysis of the drill core. NQ-size
drill core is saw cut and half the drill core is sampled in standard intervals
not exceeding 1.5 metres in length while core from the main mineralized horizons
or core displaying visible gold or significant sulfides are sampled in greater
detail generally not exceeding 1 metre in length. The remaining half core is
stored in a secure location.
Core samples are transported in security-sealed bags for analyses at ALS Chemex
Assay Laboratory, Vancouver, BC. ALS Chemex is an ISO 9001:2000 certified
laboratory. Gold assaying is done by a fire assay - atomic absorption
spectrometry method on a 30-gram charge of a 1,000 gram pulp. Samples returning
values exceeding 3 gpt Au are re-checked by fire assay with a gravimetric
finish. Pulp and metallics assaying for gold is conducted on the entire
pulverized sample for all samples within the main mineralized horizons and those
samples with visible gold or significant sulfides.
As part of its QA/QC program, Merc International Minerals Inc. inserts external
gold standards (low to high grade) and blanks every 20 samples. This is in
addition to the standards, blanks and pulp duplicates inserted by ALS Chemex. In
addition, samples of pulps have been collected from ten percent of all samples
analyzed and will be submitted to a second independent laboratory for comparison
purposes.
The Damoti Lake Gold Project is being supervised by William Waychison, M.Sc.A.,
P.Geo., the Qualified Person (QP) for this project.
