Mr. Peter Mordaunt reports
The continuing drilling at the company's Alamo Dorado silver/gold property
in Sonora, Mexico, has presented very interesting results early in the
campaign.
A recently drilled hole outside of the known resource/reserve model has
returned the highest silver grade drill intercept on the property to date.
On line 3+50 South, drill hole AD-49 has returned 52.5 metres grading 697
grams silver and 0.41 grams of gold per tonne or a silver equivalent grade
of 719 grams per tonne (based on $5.50 (U.S.) per ounce Ag and $300 per
ounce Au). This mineralization displays good continuity with the southern
extension of the starter pit area, occurring slightly deeper. The intercept
was cut from 220.5 metres to 273 metres down the hole, which was drilled
due east at minus 45 degrees (vertically -- 155 metres). Individual assay
values of high-grade gold and silver are disseminated throughout the
intercept. Moreover, no significant sulphide mineralization was identified
and the host rocks appear oxidized as are all other drill intercepts in the
reserve/resource model.
Hole AD-48 drilled on the same section (3+50 South) is thought to have been
drilled on the opposite side (south) of a cross-cutting fault where no
significant silver or gold extends directly. The company appreciates the
need for more drilling in this area.
Current plans are to systematically drill to the south of hole AD-49. Other
holes drilled to the south in past programs include AD-12, AD-11, AD-19 and
AD-36 and may not have been drilled far enough. All of these holes will be
extended as part of the continuing program. Assaying from the drill program
is carried out by Bondar Clegg Intertek Testing Services.
Other new drill holes drilled thus far in this 10,000-metre campaign are
included in the table of intercepts below:

Metallurgical work related to column leach test work is continuing. There
are now seven columns under leach that are investigating optimum size for
leaching, solution flow rates and the starter pit area. In addition, two
other columns will be loaded this week to investigate the difference in
metal extraction for low- and high-grade materials as they are represented
in the reserve/resource report completed by MINTEC Inc. last fall. The
metallurgical work will be continuing for some time to come and results are
expected on the initial work before summer.
