Alhambra Resources Ltd. (TSX VENTURE:ALH) ("Alhambra" or the "Corporation"), an
international gold producer and explorer, announces reverse circulation ("RC")
drilling results from its 100% owned advanced exploration drilling target at the
Shirotnaia project area ("Shirotnaia"). The recent 43 hole RC drilling program
has expanded the 2007/2010 core drilling defined area of gold mineralization and
has provided new priority targets for immediate core drilling follow-up.
Prior to 2010, previous drilling at Shirotnaia had identified a large gold
anomaly and significant gold mineralization with a high peak gold grade of up to
51.6 g/t (see news release dated March 4, 2010). In addition, two significant
widths of higher-grade gold mineralization were encountered within a large area
of lower grade gold mineralization, suggesting the probable continuation of the
higher-grades to depth typical of this orogenic style of mineralization. Core
drilling reported in January, 2011 (see News Release dated January 5, 2011)
yielded very encouraging results both in widths and gold grade.
Shirotnaia is located within Alhambra's 100% owned Uzboy Project in Kazakhstan
(see location map, Figure 1) and is immediately adjacent to the world-class Aksu
and Quartzite Hills gold deposits currently being mined by KazakhGold Group
Limited ("KazakhGold").
HIGHLIGHTS
-- The successful RC drilling program confirmed the presence of gold
mineralization outside the boundaries of that previously known,
-- Broad intervals of anomalous gold concentrations (for +0.15 g/t) were
intersected in 34 of 43 holes drilled,
-- Petrological studies indicate this is the top of the mineralized system
and higher-grades are anticipated at depth,
-- A link was established between previous successful core drilling
programs which proved the existence of at least one continuous and
significant higher-grade mineralized zone.
DRILLING PROGRAM
The RC drilling program completed consisted of 43 holes totaling 2,250 metres
("m"), averaging 52 m (see Figure 2). The objective of this program was to drill
the north-east extension of the mineralization, thus furthering the
understanding of the geometry of the large zone of anomalous gold
mineralization. This program provided new targets for further core drilling.
However, to ensure sample quality where high groundwater flows were encountered,
the RC holes were drilled generally shallower than planned.
Many wide, low grade, zones of oxide gold mineralization were encountered by the
RC drilling program. Petrological studies indicate that this is the very top of
the mineralized system. Furthermore, in this district, hypogene gold grades are
typically higher than the surface supergene grades. Hence, higher grades of gold
mineralization are anticipated at depth, in planned future follow-up drilling
programs. A link was also established between the successful 2007 and the 2010
core drilling programs which proved the existence of at least one continuous
1,000 m long by 15-30 m wide higher-grade mineralized zone.
A completed geochemical study from results of fire assay and inductivity coupled
plasma ("ICP") analyses of the 323 samples, taken from diamond drill holes DDH
32-02 and DDH 100-02 drilled in 2010 at Shirotnaia, concluded that:
-- The hydrothermal process in the area was developed in three major stages
but gold was mostly concentrated at the latest one, producing typical
epizonal orogenic style mineralization including concentrated Au, Ag,
Pb, Sb, Hg and less Zn. Sulfides and sulfosalts are associated with
silicification.
-- Mesothermal and epithermal style alterations at the same level implies
telescoping of the alteration zones suggesting a long-lived hydrothermal
system typical of world class districts.
-- The Hg, Sb and gold association suggests a very high level of the
hydrothermal system and possible preservation of most of the
mineralization.

The intervals set out in the above table are not true widths and the assay
results are uncut.
The drill results at Shirotnaia support the interpretation that the three zones
of gold mineralization are the northern extension of the multi-million ounce
Aksu and Quartzite Hills deposits. The combination of the hydrothermal
alteration style and distinct zones of widespread gold mineralization supports a
significantly expanded exploration program in 2011.
Upon completion of the planned 2011 drilling program, Alhambra anticipates that
a National Instrument ("NI") 43-101 resource report will be completed for
Shirotnaia by year-end 2011.
REVERSE CIRCULATION DRILLING AND SAMPLING PROCEDURES
Standard RC drilling technique was utilized and sample recovery was excellent.
The rock chips coming to the cyclone through dual tube 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.

ABOUT SHIROTNAIA
Shirotnaia is one of Alhambra's 2011 advanced drilling targets within the
Corporation's 100% owned, 2.4 million acre (9,800 km2), Uzboy Project located in
north central Kazakhstan. The Shirotnaia gold discovery is located approximately
3 kilometres ("kms") northeast of the KazakhGold Group Limited ("KazakhGold")
mining allotment which hosts the Aksu and Quartzite Hills gold deposits having
reported resources of approximately 15 million ounces(1). The large target area
of Shirotnaia, as indicated by gold soil anomaly, measures approximately 3.4 kms
by 1.5 kms and is contained within the even larger original target area of 10.0
kms by 2.0 kms which remains to be explored by more modern methods. More details
about the project geology and the previous exploration results are available on
the Corporation's website.
