Alhambra Diamond Drilling Intersects Best Gold Drill Intercepts to Date at Shirotnaia; Including 14.71 g/t Au Over 10.1 Metres
CALGARY, ALBERTA--(Marketwired - Sep 25, 2013) - Alhambra Resources Ltd. (TSX VENTURE:ALH)(PINKSHEETS:AHBRF)(FRANKFURT:A4Y) ("Alhambra" or the "Corporation"), an international gold producer and explorer, announces assay results for three diamond drill holes ("DDH") completed in 2012 at its 100% owned Shirotnaia Gold Project ("Shirotnaia") (see location map, Figure 1).
Diamond drilling has intersected higher-grade gold mineralization in DDH 28-08 that yielded a weighted average grade of 4.75 grams per tonne gold ("g/t Au") over a core interval of 33.4 metres ("m"), including 14.71 g/t Au over 10.1 m. The highest grade interval was intersected less than 100 m below surface. Together with several other drill intercepts in this area, this higher-grade interval defines a new high-grade zone of gold mineralization trending and plunging to the northwest ("NW"). These results constitute the best drill intercepts to date from Shirotnaia.
As reported in January 2012 (see Table 2 and footnotes below), Shirotnaia is a mineral resource exposed on surface within an envelope of sporadic low-grade gold mineralization and alteration that measures more than 1,800 m long and 750 m across. The current inferred mineral resource for this deposit is approximately 645,000 ounces of gold contained in 35 million tonnes at an average grade of 0.58 g/t Au using a 0.18 g/t Au cutoff. Shirotnaia is one of numerous targets on the Corporation's 9,800 square kilometres ("km2") mineral license. Shirotnaia is approximately 3 kilometres ("kms") NW of the reported multi-million ounce Aksu and Quartzite Hills Deposits currently being mined by KazakhGold Group Ltd. ("KazakhGold"). The technical information on the Aksu and Quartzite Hills gold deposits have not been verified by Alhambra.
Mr. John J. Komarnicki, Alhambra's Chairman and Chief Executive Officer commented on the drilling, "These latest Shirotnaia results are most exciting. This high-grade intercept will markedly improve the grade and thickness of this portion of Shirotnaia. Delivering our fourth Shirotnaia drill hole with more than 100 gram-metres of gold is an indication that our technical team is advancing our knowledge of this emerging discovery. Now that we have identified new targets of structurally controlled high-grade shoots, follow-up drilling will likely result in an increase in both the tonnes and grade of gold mineral resources at Shirotnaia."
DRILLING PROGRAM SUMMARY
In 2012 the Corporation completed 18 DDH totaling 3,691 m. The average depth of the holes was 205 m. In late 2012, the Corporation reported assay results for eight of those holes, totaling 1,408 m (see News Release dated November 14, 2012). The objective of the 2012 drilling program was to confirm and extend the previously identified higher grade gold mineralization zones along strike and to depth (see News Releases dated March 10, 2010 and April 28, 2011). The results to date indicate that this objective has been achieved, resulting in a number of new targets requiring follow-up drilling.
Due to the Corporation's recent financial difficulties, it has been forced to conserve its working capital and defer payment of some invoices. As a result, assay results are being reported as received from the laboratory. At the time of this release, the assays are still pending for 7 DDH from the 2012 drill program. The results from the three DDH discussed here are summarized in Table 1 and Figures 2 and 3.
The geological model of the Shirotnaia gold mineralization includes an interpreted higher-grade (+1.0 g/t Au) zone that is about 1,200 m long and has variable width (see Figure 2). The higher-grade zone is interpreted to trend more E-W than the broader mineralized zone, which is orientated NE-SW. The higher grades are controlled by shear zones, cross structures and related breccias and are generally related to more intense alteration, including pervasive silicification. The mineralized zones dip generally to the NW at an angle of 60°to 70°.
The most significant intervals that were received are summarized in more detail below:
The best mineralized interval reported was in DDH 28-08, which yielded a weighted average of 33.4 m @ 4.75 g/t Au (including 10.1 m @ 14.71 g/t Au) and 13.0 m @ 1.46 g/t Au (including 2.0 m @ 7.60 g/t Au). This hole included numerous other significant intercepts up to 19.6 m in thickness and bottomed in low-grade mineralization at 280.1 m. The hole was steeply inclined in a SE direction, targeted as a 25 m step-out to the NE from DDH 28-09 (see news release dated November 14, 2012), which yielded 136 m of 1.12 g/t Au, including some higher grades over narrower widths. The 2012 Shirotnaia mineral resource does not include results from either of these drill holes.
The broad and higher-grade mineralization in this area is related to a NW striking cross-cutting structure. This structure exhibits significant higher-grade gold values associated with intense silicification, carbonate veining, sulphides, and quartz veining. The higher-grade mineralization extends and deepens the +1 g/t Au mineralization reported in the resource estimate dated January 9, 2012. This zone remains open to the NW and at depth; and it is also poorly constrained on the NW and SE (see Figure 2).
DDP 15-14 targeted the area between the western end of the higher-grade zone and the mineralization situated farther to the west and drilled in 2007. The higher-grade mineralization comes to surface in this area, resulting in a weighted average of 8.9 m of 4.07 g/t Au in oxide to transitional material, including a 1.0 m intercept of 30.9 g/t Au from 16 to 17 m depth. This narrow high-grade interval is open to the west (see Figure 2). Having confirmed the presence of the high-grade mineralization on the west end of the deposit, follow-up drilling will focus on identifying cross structures and other controls on this good quality mineralization.
DDP 52-04 intercepted four narrow zones of mineralization down to 157 m below surface. This step out drill hole targeted the deeper part of the higher grade zone established by hole DDH 52-01 (21.3 m @ 1.43 g/t Au), and is in an area of relatively sparse drilling.

SHIROTNAIA REGIONAL SETTING AND MINERALIZATION
Shirotnaia is just one target within Alhambra's 9,800 km2 (2.4 million acre) mineral license, located in the world-class Central Asia-Chinese Altayshan Gold Belt.
At Shirotnaia, gold mineralization consists of numerous zones of intensive hydrothermal alteration occurring within a generally east-west oriented, structurally controlled, low grade gold aureole, which is at least 1,800 m long, 750 m wide. Mineralization remains open in several directions as well as at depth. Four zones of gold mineralization are presently known in the explored portions of the system.
The gold mineralization at Shirotnaia is hosted in a sequence of mostly dacitic to andesitic volcanic and volcaniclastic rocks. The oxidized zone extends to an average depth from surface of about 20 m and a transition zone about 16 m thick below that, underlain by primary gold mineralization.
DRILLING AND SAMPLING PROCEDURES
For the core drilling, an NQ diamond drilling core barrel was utilized and core recovery was close to 100%. The core was split by the drilling contractor under the supervision of the Corporation's geologists with one half sampled for assay and another half left for references. Every metre of core was sampled and the exact borders of the sampling interval were determined according to the lithological contacts. The average sample weight was 2.0 kilograms.
Sample preparation was completed by Stewart Assay and Environmental Laboratories (now part of the ALS Group) 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 is accredited to International Standard Organization ("ISO") 17025 for certain relevant assay methodologies.
QUALITY ASSSURANCE QUALITY CONTROL
The Kyrgyzstan Stewart Assay and Environmental Laboratories 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.
