19 Mayo 2011 - 7:00AM
Marketwired Canada
Alhambra Resources Ltd. (TSX VENTURE:ALH)(PINK SHEETS:AHBRF)(FRANKFURT:A4Y)
("Alhambra" or the "Corporation"), an international gold producer and explorer,
announces that its diamond drilling program at Dombraly has resulted in the
discovery of four new zones of gold mineralization. In addition,
reverse-circulation drilling intersected significant gold mineralization in both
the low-grade stockpile and material used to back fill the old open pit. The
former Dombraly gold mine ("Dombraly") is located within Alhambra's 100% owned
Uzboy Project in Kazakhstan (see Figure 1).
HIGHLIGHTS
-- The successful diamond drilling program intersected four new zones of
gold mineralization (see Figure 2),
-- The new zones of gold mineralization located south of the Dombraly open
pit have increased the strike length of the Dombraly mineralized zone by
300 metres ("m"). Mineralization is mainly oxide with average gold
grades ranging from 0.45 to 3.95 grams per tonne ("g/t") and a high peak
sulfide gold grade of 40.50 g/t over 1.0 m,
-- The new zone located north of the Dombraly open pit is outside of the
previously known areas of gold mineralization, is open to the north, is
estimated to be more than 100 m long and varies in width from 9 to 14 m.
Mineralization is sulfide with average gold grades range from 0.48 g/t
over 10.0 m to 4.08 g/t over 4.3 m included in a gold grade of 2.06 g/t
over 10.3 m and a high peak gold grade of 10.30 g/t,
-- RC drilling intersected significant gold mineralization in both the low-
grade stockpile and the material used to back fill the old open pit (see
Figures 3a and 3b). The low-grade stockpile gold grades ranged from less
than 0.1 to 19.3 g/t while the back fill material gold grades ranged
from 0.1 to 11.2 g/t.
Mr. John J. Komarnicki, Alhambra's Chairman and Chief Executive Officer stated,
"The discovery of four new zones of gold mineralization at Dombraly has very
exciting implications for Alhambra! Dombraly was one of our 2010 priority
exploration targets and will continue to be a priority for 2011. We are very
excited about this drilling program for the positive results should allow us to
re-classify the historical Soviet resource and reserve data (which has been
acknowledged by the Kazakhstan State Reserve Committee) into a compliant
National Instrument 43-101 resource estimate for Dombraly, as it should be."
DRILLING PROGRAM OBJECTIVE
Alhambra's focus was to further define the extent and continuity of the gold
mineralization at Dombraly, leading to a National Instrument ("NI") 43-101
compliant resource estimate (see News Release dated May 10, 2010). Alhambra has
engaged the independent geological and mining consultants, ACA Howe
International Limited to consult on the drilling program in preparation for the
resource estimate.
DRILLING PROGRAM SUMMARY
The 2010 drilling program at Dombraly consisted of 8,511 m (see News Release
dated May 3, 2011) of core and non-core drilling (see Figure 2). Three different
types of drilling were conducted and the meterages are as follows:
-- 3,788 m of diamond drilling (a 15 core hole program),
-- 883 m of reverse-circulation ("RC") drilling (37 holes), and
-- 3,840 m of rotary air-blast ("RAB") drilling (192 holes).
1. DIAMOND DRILLING
Of the 3,788 m of diamond drilling, 1,682 m were drilled south of the known
zones of gold mineralization where the gold mineralization is open-ended and
2,106 m were drilled at the northern flank of the Dombraly main zone of gold
mineralization.
Three new zones of gold mineralization were discovered south of the
mineralization that has been explored by previous core drilling (see Figure 2).
These new zones, mainly represented by shallow oxide material, have increased
the known mineralization strike length by 300 m and are up to 7 m in width with
average gold grades ranging from 0.45 to 3.95 g/t (see Table 1). However, DDD
00-03 also intersected sulfide mineralization with a gold grade of 40.50 g/t
over 1.0 m. At least one of the zones could be extended further to the south
with additional drilling and all together, they could significantly add to the
resources at Dombraly.
Drilling north of the open pit resulted in the discovery of a new zone of
sulfide gold mineralization (see Figure 2). As this zone was open to the north,
it could only be approximated as being more than 100 m. Its total width ranges
from 9 to 14 m and is traced up to 250 m along the dip. This new zone,
intersected in DDH 48-03, has an average gold grade of 4.08 g/t over 4.3 m
included in an interval with a gold grade of 2.06 g/t over 10.3 m (see Table 1).
Individual gold grades ranged from 0.13 to 10.3 g/t. This zone is a blind zone
(not outcropping on the surface) and being established northward of the known
limit of the mineralization, could significantly increase the size potential of
the Dombraly deposit. This northern extension has revealed a new expanded area
for further exploration drilling.
2. RC DRILLING
The gold mineralization in the existing low-grade stockpile and associated open
pit back-fill, generated by a mining cooperative in the mid 1980s, was drilled
via RC drilling to validate and reclassify the historical Soviet resource and
reserve data. Alhambra anticipates this data would be included in a NI 43-101
resource estimate (Note: Soviet resources and reserves are not compliant with NI
43-101 and, although meaningful, no resources or reserves to date have been
defined at Dombraly). Another objective of the RC drilling was to check for near
surface oxide gold mineralization northward of the open pit.
The locations of the 37 RC holes completed at Dombraly are shown in Figures 2
and 3. The depth of the RC holes ranged from 40 to 57 m.
Gold grades in the low-grade stockpile are not homogeneous in distribution (see
Table 2 and Figure 3a) and ranged from less than 0.1 g/t to 19.3 g/t. The
significant range in gold concentration suggests a significant nugget effect.
The thickness of the mineralized intervals in the low-grade stockpile outlined
using a 0.1 g/t gold cut-off varies from 2 to 20 m. It is anticipated that the
data from this RC drilling program would be used in an initial NI 43-101
resource estimate.
The open pit back fill material ranged in depth from 24 m to 74 m (see Table 3
and Figure 3b). The objective of this drilling was to prove the presence of a
significant amount of gold in the material used to back fill the old open pit.
The average gold concentration of the back fill material is approximately the
same as in the low-grade stockpile and ranges from 0.1 g/t to 11.2 g/t. The gold
distribution in the back fill material is more homogenous than the low-grade
stockpile.
3. RAB DRILLING
RAB drilling was completed south of the low-grade stockpile, as well as 900 m
north-east of the open pit, to follow-up gold anomalies in both rock and soil.
Previously reported grab rock samples in these areas returned up to 5.6 g/t
gold. Alhambra will announce the results of the RAB drill program upon receipt
and interpretation of drill assays.

Based on the results of the 2010 diamond drilling program at Dombraly, the
Corporation anticipates a more aggressive 2011 drilling program at Dombraly
including a large number of core holes.
As a part of Alhambra's 9,800 square kilometre ("km2") mineral license located
within the Central Asia-Chinese Altayshan Gold Belt traversing northern
Kazakhstan, the Corporation controls at least 50 kilometres ("kms") of a rapidly
emerging significant gold trend. This trend extends from the gold mineralization
exposed at North Balusty in the north to Shirotnaia in the south and includes
the Dombraly gold deposit and gold mineralization exposed at Kerbay (see Figure
4 and previous news releases made by Alhambra regarding North Balusty,
Shirotnaia and Kerbay). This gold trend extends south of Alhambra's license and
hosts the multi-million ounce Aksu and Quartzite Hills gold deposits held by
KazakhGold Group Limited located approximately 3 kms southeast of Alhambra's
Shirotnaia Project.
DRILLING AND SAMPLING PROCEDURES
For the core drilling, an NQ diamond drilling core barrel was utilized and
average core recovery was 99%. The core was split by the drilling contractor
under the supervision of the Corporation's geologists with one half used for
sampling and another half left for references. Every meter of core was sampled
and the exact borders of the sampling interval were determined according to the
lithological contacts. The average sample weight was 2 kilograms.
For the RC drilling, a standard technique was utilized and sample recovery was
excellent. The rock chips coming to the cyclone through dual tubes were split
using a riffle splitter by the drilling contractor under the supervision of the
Corporation's geologists. Every meter of hole was sampled. The average sample
weight was 5 kilograms.
Sample preparation was completed by Stewart Assay and Environmental Laboratories
located in Kyrgyzstan using the following procedure: samples were crushed to
minus 2 mm, mixed and split into two 200 gram sub-samples. One sub-sample was
pulverized to - 200 mesh and the other sub-sample was retained for reference
purposes. A 30 gram sample of the -200 mesh material was used for fire assay
atomic absorption finish. Stewart Assay and Environmental Laboratories is
independent of Alhambra and does have an International Standard Organization
("ISO") 17025 accreditation.
QUALITY ASSSURANCE QUALITY CONTROL
The Kyrgyzstan Stewart Assay and Environmental Laboratories, as a part of
Stewart Group, have stringent quality assurance and quality control ("QA/QC")
procedures. Alhambra also follows a rigorous QA/QC program consisting of
inserting standards, blanks and duplicates into the sample stream submitted to
the laboratory for analysis to ensure that the sampling and analysis of all
samples is conducted in accordance with the best possible practices.
