/PRNewswire-FirstCall/ -- Mountain Boy Minerals Ltd. announce that
a drilling program on Mountain Boy's 100% owned MB property
confirmed bonanza style silver mineralization. The MB property is
located about 22 kilometres north of Stewart and is road accessible
along the American Creek valley. Replacement type mineralization on
the property consists of at least seven main and four minor
replacement zones tested with trenches, previous open cuts, limited
diamond drilling and/or adits in the past. The mineralization
occurs along wide bodies that are up to 15 meters thick consisting
of mainly barite, quartz, jasper, carbonates and sulfides with
local native silver. Acanthite (silver sulphide) and stromeyerite
(silver-copper sulphide) occur as veinlets, stringers and lenses in
the High Grade and No 3 vein, giving rise to bonanza style grades.
Between 1929 and 1938, the MB property produced 60 tons of hand
cobbed material that yielded an average 546.8 oz/ton silver, 3.2 %
copper and 3.15 % lead per ton of ore. In 1940, mining extracted
3.08 tons grading an average 0.09 oz/to gold, 248 oz/ton silver,
2.2 % copper, 4.9 % lead and 5.8 % zinc. In 1999, Mountain Boy
Minerals extracted a13.6 tonne (15 ton) sample from the High Grade
vein with results from the smelter indicating a value of
18,854-grams/tonne silver (550 oz/ton), 1.1 % zinc and 2.5 % lead
for this shipment. Based on the surface and underground sampling
and drilling, an indicated resource totaling 105, 555 tonnes
grading 0.064 % copper, 0.69 % lead, 2.01 % zinc, 208.9 g/t silver
and 13.59 % barite has been outlined in a very small portion of
three different veins. A complete report is filed on Sedar dated
June 20, 2003. Due to the steep nature of the terrain, a drill
station was blasted out below the High Grade vein and 14 holes
drilled from this station using an underground drill to fan a
series of holes from this location. In the course of stripping of
the High Grade vein using a small excavator in order to build the
drill station, massive acanthite (argentite) stringers up to 15 cm
wide were exposed along several meters of length in a fault zone
that intersects the vein. The full length of the mineralization was
not exposed due to the deep overburden on either end of the
exposure. This orientation of veining has never been seen in the
past and may represent feeders to high grade mineralization found
in the High Grade and No 3 veins. Grab sampling of these stringers
has yielded over 15,000 g/t silver. Results from the short holes
drilled at this station are listed below:

It should be noted that the High Grade vein has only been tested
along a 100 meter section in the southern portion of the Mountain
Boy claim. Based on newspaper accounts, bonanza style silver
mineralization apparently occurs several hundred feet (60 meters)
south of the area of drilling. In addition the No 3 vein located
100 meters topographically above the High Grade vein has reported
grades that contain 0.91 meters of 12,917 g/T, 0.46 meters of
18,361 g/T, 0.91 meters of 13,569 g/t and 1.22 of 6,361 g/T silver
over a strike length of 100 meters along this vein.. The High Grade
vein has been traced over a length of 457 meters and the No 3 vein
has been traced over a strike length of 550 meters. The No 3 vein
appears to strike into the former Silver Mask claim (present
Stromeyerite claim owned by Mountain Boy) which appears to have
similar high grade mineralization. On the Silver Mask claim, an
article in the June 28, 1929 edition of the Stewart News indicates
that a vein 1.83 meters (6 feet) wide was located on this claim.
The article describes the vein as similar to the High Grade vein on
the Mountain Boy property approximately 500 meters away with
"copper sulphides mixed with bunches and stringers of native
silver. Four additional veins have been located, some of them with
similar high grade ore and some carrying galena in massive form".
Future work will try to locate all previously reported
mineralization on the High Grade and Mo 3 vein as well the showings
on the former Silver Mask claim and extend the known strike length
of the cross-cutting massive argentite found during stripping for
the drill station.. E. Kruchkowski, P. Geo., a qualified person
under National Instrument 43-101, is in charge of the exploration
programs on behalf of the Company. Drill core and trench samples
are assayed by Assayers Canada of Vancouver, BC. Mountain Boy
Minerals Ltd is a Canadian based mineral exploration company whose
activities are in the Stewart and McKenzie area of BC. It is
actively exploring for gold-silver-base metals on the Silver Coin
project, silver-base metals on their American Creek properties,
copper-gold in the Stewart area, porphyry molybdenum in the Stewart
and McKenzie areas and copper-nickel-platinum group metals in the
McKenzie area. ON BEHALF OF THE BOARD "Ed Kruchkowski" Ed
