Additional Positive Diamond Drill Results at Shirotnaia
CALGARY, Canada, June 28 /PRNewswire/ -- Alhambra Resources Ltd. ("Alhambra" or the "Corporation") announces the
results for the last 6 of the 18 diamond drill holes ("DDH") completed in
2007 on the Shirotnaia zone within its Uzboy Project area in the Republic
of Kazakhstan.
Mr. Elmer B. Stewart, President, COO and the designated Qualified
Person for Alhambra stated, "We are very excited about the analytical
results from the remaining 6 DDH since the grade and continuity of the gold
mineralization in these holes combined with the 2006 trenching results
support the interpretation that the Shirotnaia zone is a continuous 1,350
metre ("m") zone of gold mineralization. Due to these positive results and
the close proximity of the Shirotnaia zone to the producing gold deposits at
Aksu, additional exploration, including diamond drilling, is planned for
Shirotnaia later in 2007."
The Shirotnaia zone is located 3 kilometres ("kms") northeast of the
Aksu and Quartzite Hills gold deposits. These two gold deposits are
operated by KazakhGold Group Limited ("KazakhGold") and are reported in a
prospectus filed in November 2005 to support KazakhGold's listing on the
London Stock Exchange to have Proven and Probable gold reserves of 5.4
million and 10.0 million ounces of gold resources, respectively. Alhambra's
Qualified Person has not verified the resource and reserve information set
out in KazakhGold's prospectus. The resources and reserves set out in the
KazakhGold prospectus do not comply with definitions of resources and
reserves as defined by the Canadian Institute of Mining and Metallurgy and
the Standard of Disclosure for a Mineral Property. The gold mineralization
in the Aksu gold deposits is not necessarily indicative of the gold
mineralization in the Shirotnaia zone. The geology and structures that
hosts these two gold deposits are interpreted to extend northeast towards
the Shirotnaia zone.
Diamond Drilling Results
Seventeen of the 18 DDH completed (including 5 of the last 6 holes
drilled) over a strike length of 1,350 m within the Shirotnaia zone have
intersected multiple intervals of significant gold mineralization (greater
than 0.2 grams/tonne ("g/t")) in each hole. The mineralized intervals range
in thickness from 2.0 to 73.0 m and extend from surface to a depth of 125 m
on Section 28.
The results for 12 of the 18 DDH were previously reported in
Alhambra's News Releases dated March 21, 2007 and April 26, 2007. The
locations of the 18 DDH are shown in Figure 1 (see Figure 1 at the
following link: http://files.newswire.ca/483/Figure1ShirotnaiaZone.doc).
The weighted average grade of the mineralized intervals was estimated using
atomic absorption analysis, a 0.2 g/t cutoff and no top cut. The weighted
average grade of the mineralized intervals for the last 6 of the 18 hole
drilling program are shown in Table 1.
Detailed Results - Shirotnaia Zone
Five of the last 6 DDH drilled have intersected multiple intervals of
significant gold mineralization (see Table 1). DDH C-871 and DDH C-872 were
drilled on Profile 87 (see Figure 1 at the following link:
http://files.newswire.ca/483/Figure1ShirotnaiaZone.doc) to test the depth
extent of gold mineralization located by a trenching program completed in
2006. DDH C-872 was drilled below DDH C-871 and intersected four intervals
of significant gold mineralization. DDH C-871 was located too far south and
failed to intersect the mineralization exposed in trenches on this profile.
DDH C-1, DDH C-2 and DDH C-3 were drilled on Profile 0. DDH C-2 and
DDH C-3 are interpreted to have intersected a separate zone of gold
mineralization located approximately 40 m northwest of the mineralization
intersected in DDH C-1. DDH C-1 is interpreted to have intersected the
southwest extension of the mineralization intersected on Profiles 12, 20
and 28 and previously reported in Alhambra's News Release dated March 21,
2007.
DDH C-242 was drilled on Profile 24 to test the down dip extension of
the gold mineralization in DDH C-241. The mineralization in DDH C-242
consists of three narrow intervals which is significantly different than
the two wide mineralized intervals (39.7 m and 41.0 m, respectively)
intersected in DDH C-241.
The geology of the Shirotnaia zone consists of middle Ordovician
dacite and andesite sub-aerial volcanics and tuff that have been intruded
by granite dikes. The gold mineralization is interpreted to be controlled
by the northeast trending Aksuyski fault zone. The upper portions of the
mineralized intervals are oxidized to an average depth of 25 metres. The
gold mineralization is hosted in metasomatically (sericite-pyrite-quartz)
altered dacite and andesite. Underlying the oxidized zone, the mineralized
intervals are characterized by fine grained disseminated pyrite, pyrite
veinlets and quartz-carbonate veining. The pyrite content of the
mineralized intervals ranges from 1% to 7%.
The preliminary interpretation of the results for the 18 hole
drilling program suggests that the gold mineralization intersected on
Profiles 103, 87 and 71 is the southwest extension of the gold
mineralization intersected between Profiles 0 and 32. Although no drilling
has been completed between Profile 0 and Profile 71 (a distance of 710 m),
trenching completed in this part of the Shirotnaia zone in 2005 and 2006
intersected significant intervals of gold mineralization (see Alhambra's
News Releases dated December 5, 2006 and February 23, 2006). The
mineralized intervals in all 17 holes are open along strike and at depth.
Between Profile 24 and Profile 28 an interpreted northwest trending fault
appears to offset the mineralized zones between these two sections.
The mineralization between Profiles 0 and 32 (a distance of 320 m) is
the most significant intersected to date with respect to average gold grade
and width of mineralization. The mineralization is interpreted to dip
steeply (75 degrees) to the West, ranges from 10 to 70 m in thickness and
has been intersected to a depth of 125 m on Profile 28. The analytical
results for DDH C-281 (1.79 g/t over 73 m) and DDH C-282 (1.80 g/t over 38.
8 m) were reported in Alhambra's News Release dated March 21, 2007. DDH C-
282 was terminated at a depth of 142.8 m in significant gold mineralization
with the last sample in this hole yielding a gold grade of 1.33 g/t.
The mineralization intersected in DDH C-2, DDH C-3 and DDH C122 (see
Alhambra's News Release dated April 26, 2007) appears to be a separate zone
located approximately 40 m north of the mineralization intersected between
Profile 0 and Profile 32. DDH C-1 is interpreted to have intersected the
southwest extension of the mineralization intersected between Profile 12
and Profile 32.
DDH C-872 intersected four steeply dipping (80 degrees) sub-parallel
zones of gold mineralization. These mineralized intervals are interpreted
to be the northeast extension of the mineralization intersected in DDH C-
1031 and DDH C-1032. The mineralized intervals in this part of the
Shirotnaia zone are interpreted to dip to the West and are open along
strike and at depth.

Diamond Drilling and Sampling Procedures
Diamond drilling is completed using a 76 mm diameter core barrel. Core
recovery is estimated to be greater than 97%. After cutting with a diamond
saw, one half of the core is collected for sample preparation and analysis
and the other half is retained for future reference. Sample intervals were
selected based on lithologies and intensity of alteration. The sample
interval and sample weight averaged one-meter and 2.0 kilograms
respectively. Sample preparation was completed by Chemical and Analytical
Laboratory Quartz LLP located in Stepnogorsk, Kazakhstan using the
following procedure: core samples were pulverized in a jaw crusher to minus
1 mm, mixed and split into two 0.75 kilogram sub-samples. One sub-sample is
ground to -200 mesh and the other sub-sample is retained for reference
purposes. A 10 gram sample of the -200 mesh material is used for atomic
absorption analysis and the balance is retained for fire assaying and
reference purposes. Chemical and Analytical Laboratory Quartz LLP is
certified in the Republic of Kazakhstan, does not have an International
Standard Organization ("ISO") rating and is independent of Alhambra.
Quality Control
Alhambra follows a rigorous Quality Assurance/Quality Control program
consisting of inserting standards, blanks and duplicates into the sample
stream submitted to the laboratory for analysis.

Corporation's nominated Qualified Person responsible for monitoring the
