Millrock Announces Positive Drilling
and Sampling Results at Bluff Project, Alaska
January
22, 2009
VANCOUVER,
BRITISH COLUMBIA, January 22, 2009. Millrock Resources Inc. (MRO - TSX:V)
("Millrock" or the "Company") is pleased to announce
results from drilling at the Daniel's Creek prospect and surface sampling at
the Koyana prospect of the Bluff Project, east of Nome, Alaska.
Highlights
of the Daniel's Creek prospect drilling program include:
- 5.94 meters 1.397 g/t gold in hole BLF1001
- 1.37 meters 3.819 g/t gold in hole BLF1003
"We
are pleased with the outcome of this drilling program. We had encouraging
near-surface intersections of gold mineralization in all five short holes
drilled, even though it was diminished by poor drill production,"
commented Gregory Beischer, Millrock President & CEO. "While we were
unable to verify the previously reported resource, the 2008 drill program was
not a fair test of the property, with only 400 meters of the planned 1,500
meter drill program completed. We hope to accomplish more drilling in 2009 to
further test this prospect as well as the other great targets on the
property. "
Five holes
totaling 403.26 meters were drilled with a goal of substantiating historic
drill results reported by BHP and expanding the estimated boundaries of the
reported mineralization to previously untested soil anomalies. The following
table provides a list of all mineralized intersections using a cutoff grade
of 0.5 g/t gold.

The true
thicknesses of these intercepts are unknown. Mineralization orientations are
unknown due to a lack of outcrop and strongly broken ground.
Reconciling
the 2008 drill program with BHP's 1987 to 1990 drill program has proven
problematic. Consistent lack of repeatability of all comparisons of past and
recent drilling, duplicate samples and re-sampling of past drill core suggest
an underlying nugget effect. The challenge of reconciling past and recent
drill programs is magnified since both programs experienced very low core
recoveries due to strongly broken ground. It is unclear which of the BHP or
Millrock 2008 drill programs are more representative of true grade since a
nugget effect and low core recoveries can both upgrade and/or downgrade assay
values.
Millrock's
2008 drill program was designed to minimize a nugget effect through drilling,
sampling, sample preparation and assaying procedures and maximize core
recovery through drill techniques. Despite best efforts, ground conditions
limited core recovery to 75% - an improvement over drill core recoveries
obtained by BHP. Duplicate assays and re-assays of Millrock samples also have
the highest correlation of all the programs, but inconsistencies are still
exhibited throughout the results. Future drilling will have to more
aggressively address low recovery issues and a nugget effect.
The Koyana
zone, which is located approximately 2.7 kilometers east of the Daniel's
Creek prospect, is known from three prior BHP drill holes. Prospecting and
surface sampling carried out by Millrock in 2008 extended this zone 500
meters southeast to what is now known as the Koyana Beach showing. Grab
samples of quartz-carbonate-arsenopyrite veins returned strong assay results
at this location. The following table provides highlights of these results:

The
intervening area between the known drill intercepts and the beach showing has
not been drill tested and is a target for future drilling programs.
Additionally, at the Saddle Zone a drill intersection of 5.4 g/t over 10.9
meters previously reported by BHP warrants follow-up drilling.
Large soil
anomalies in the surrounding area remain untested and are potential targets
for future drilling programs.
For
Millrock's 2008 Bluff exploration program, mineralized intervals were sampled
and placed in sealed bags then delivered to Alaska Assay Lab in Fairbanks,
Alaska for analysis. Each sample was screened for metallics and a 1000-gram
aliquot was used for a fire assay atomic absorption finish. The core was not
split because of gold loss problems previously encountered at this property
and other nearby properties. All core was carefully logged and photographed
with visible depth markers. All unanalyzed drill core and coarse rejects from
the core samples have been retained for geological record. A sample quality control/quality
assurance program was implemented and results of the program determined to be
acceptable.
The Bluff
prospect is situated about 100 kilometers east of Nome and 35 kilometers
south of the village of Council on one of three land parcels that are the
subject of a previously announced agreement between Millrock and the Bering
Straits Native Corporation, owner of the prospect's mineral rights. White
Mountain Native Corporation is the owner of the prospect's surface rights.
The Bluff prospect is on the coast with barge and landing craft-accessible
beaches, an airstrip and the Nome-Council seasonal gravel road providing
ready access for personnel and equipment. Nome is serviced by three scheduled
jet aircraft flights a day from Anchorage, daily air freight service, and has
a small port for use for barge delivery of fuel, supplies, and equipment from
the Pacific Rim.
The 2008
exploration program at the Bluff Project was supervised by Millrock President
and CEO, Gregory Beischer, a Qualified Person as defined by NI 43-101 who
