The Dombraly 2011 Core Drill Program Discovers New Zones of Gold Mineralization and Significantly Extends and Upgrades Other ...

Alhambra Resources Ltd. (TSX VENTURE:ALH) (PINKSHEETS:AHBRF) (FRANKFURT:A4Y)
("Alhambra" or the "Corporation") announces that its core drilling program at
the Dombraly gold deposit ("Dombraly") has resulted in the discovery of two new
zones of higher grade gold mineralization and has extended the known areas of
gold mineralization both north and south. Dombraly is located within its 100%
owned Uzboy Project in Kazakhstan (see location map, Figure 1).
HIGHLIGHTS
-- At least five known zones of gold mineralization have been significantly
extended or the mineralization in these zones has been upgraded in terms
of both grade and width, the best mineralized intervals being 17.29 g/t
over 3.9 m, 4.40 g/t over 14.1 m and 3.57 g/t Au over 14.7 m,
-- Two new zones (i.e. lenses) of gold mineralization have been discovered,
one being a northern extension of the hanging wall mineralized lens 1
(see Figure 3) with a maximum grade of 9.95 grams per tonne gold ("g/t
Au") over 1.5 metres ("m"), and the second being two new foot wall zones
situated below the main mineralized zone with maximum grades of 1.66 g/t
Au over 8.2 m and 1.18 g/t Au over 4.0 m.
"These drill results continue to support our interpretation that the gold
mineralization at Dombraly has the potential to increase significantly," stated
Mr. John J. Komarnicki, Alhambra's Chairman and Chief Executive Officer. "In our
opinion, the discovery of these new zones of gold mineralization combined with
the significant extension of previously known mineralization supports an initial
2012 Dombraly exploration program of seven core drill holes (2,200 m) which will
be focused on further defining the upside potential of Dombraly."
DRILLING PROGRAM
The 2011 drilling program consisted of 32 core holes (5,528 m) of which 28 core
holes (4,938 m) were drilled in the central part of Dombraly and 4 scout holes
(590 m) were drilled far beyond its southern edge southward of the low grade
stockpile (see Figure 2).
The objective of the 28 core hole drilling program was to allow further
re-classification of historical Soviet resources ultimately leading to an
updated National Instrument ("NI") 43-101 compliant resource estimate and to
further define the extent and continuity of the gold mineralization at Dombraly.
The objective of the 4 scout hole drill program was to check the main tectonic
zone which had been recognized as a main gold mineralization controlling
structure and to check the weak gold anomaly established there by the 2010
rotary air-blast ("RAB") drilling program.
The 28 core hole program has been successful as the program has discovered two
new zones of gold mineralization and further extended the known areas of at
least five known zones of gold mineralization. Table 1 summarizes the results of
the holes drilled in the central part of the deposit. The 4 scout hole program
did not encounter gold mineralization.
A newly discovered northern extension of the hanging wall (situated above the
main mineralization zone) mineralized lens 1 (between hole DP 44-26 and hole DDD
52-01 and taking into account holes DDD 48-03 and DDD 48-04 drilled in 2010) has
been identified as being about 120 m long and 1.5 to 20.8 m wide remaining open
to the north. The average gold grades in different intercepts of this
mineralization range from 0.77 g/t over 20.8 m to 9.95 g/t over 1.5 m. At the
same time the known southern part of lens 1 has been significantly upgraded when
hole DP 40-25 discovered its uppermost (closest to the surface) part which was
displaced by a fault (see Figure 4). The thickness (along the hole) of this new
oxide mineralization is 14.7 m with an average gold grade of 3.57 g/t.
Drill hole DP 28-21 has discovered a new, uplifted, faulted part of mineralized
lens 2 at the hanging wall of the main zone of gold mineralization. This new
mineralized part is about 65 m along the dip and 14.1 m thick (along the hole)
with an average grade of 4.40 g/t Au in transitional material. This hole has
also extended the main zone of gold mineralization and lens 3 by about 40 m
along the dip and confirmed the presence of lens 1 at depth (see Figure 3).
Two new foot wall mineralized lenses, situated below the main mineralization
zone, have been discovered by hole DP 12-07. The lenses demonstrated significant
width (4.0 m at 1.18 g/t Au and 8.2 m at 1.66 g/t Au) along the hole of
transitional mineralization and remain open along strike in a northerly
direction.
Three of four mineralized zones identified in 2010 on the southern edge of the
deposit have now been extended by at least 60 m. One of these zones containing
oxide mineralization, and intersected by hole DDD 21-02, consists of several
subzones forming probably a tectonic duplex with a width of 50 m. Average grades
in these subzones reach 1.52 g/t Au over 3.0 m (not true width). All zones
remain open to the south.
Drill hole DP 24-18 (located immediately south of DP 28-21), extended lens 2 by
65 m along the dip. Drill hole DP-10, located 200 m farther to the south, after
an interval of relatively low grades, returned 0.91 g/t Au over 14.3 m at a
depth of about 140 m along the lens dip. Hole DP 04-02 intercepted and further
extended lens 2, showing several mineralized intervals, the best being 2.01 g/t
Au over 9.0 m in oxide material, and confirmed the continuity of gold
mineralization in this direction.

The intervals set out in the above table are not true widths and the assay
results are uncut. The cut-off grade used is 0.2 g/t Au and the maximum internal
waste is 2.0 m.
The Corporation anticipates that the presence of numerous new significant
mineralized lenses, especially in the hanging wall of the Main zone, should lead
to a significant increase of resources, as compared to the resources estimated
in the maiden NI 43-101 for Dombraly (as noted at the end of this news release).
DIAMOND DRILLING AND SAMPLING PROCEDURES
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 2.4 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 the
worldwide ALS 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.
