Alhambra Announces Maiden NI 43-101 Gold Resource Estimate for Shirotnaia; 71,000 Ozs Indicated and 645,000 Ozs Inferred

Marketwired

CALGARY, ALBERTA--(Marketwire - Feb. 28, 2012) - Alhambra Resources Ltd. (TSX VENTURE:ALH.V - News) ("Alhambra" or the "Corporation"), an international gold explorer and producer, announces that the Corporation has received the results of an initial independent National Instrument 43-101("NI 43-101") gold resource estimate (the "Estimate") for Alhambra's 100% owned Shirotnaia Gold Project ("Shirotnaia"). Shirotnaia is one of three advanced exploration project areas Alhambra is exploring within its 9,800 square kilometre ("km2") (2.4 million acre) Uzboy Gold Project located in north central Kazakhstan (see location map, Figure 1).

The Estimate was prepared by ACA Howe International UK ("ACA Howe") and Micromine Consulting Services UK ("MCS"). The Estimate includes all exploration data up to October 30, 2011. The final technical report will be filed within the regulatory required 45 days on SEDAR at www.sedar.com and will be posted on the Corporation's website.

Mr. John J. Komarnicki, Alhambra's Chairman and Chief Executive Officer stated, "The initial NI 43-101 resource estimate of 421,000 ounces of gold at a cut-off of 0.5 grams per tonne gold ("g/t Au") and a grade of 1.03 g/t Au certainly supports our confidence that this is just the beginning of our understanding of a potentially very extensive and complex deposit. The 2010/11 drilling program attempted to define the limits of this large deposit. The drilling results identified thirteen mineralized domains which remain open along strike and depth. The higher grade lodes which are now known to exist, and whose contribution to the average grade has been greatly diluted in the current estimate by the lower grade blocks, will be followed up with focused and closer spaced drilling in 2012 with the objective of increasing resources and gold grade."

HIGHLIGHTS





--  The Estimate represents the maiden NI 43-101 gold resource estimate for

    Shirotnaia, 

--  645,000 ounces ("ozs") of Inferred mineral resources contained in 34.6

    million tonnes grading 0.58 g/t Au have been identified (see Table 1), 

--  An additional 71,000 ozs of Indicated mineral resources contained in 2.9

    million tonnes grading 0.76 g/t Au were identified (see Table 1).



The Estimate, as summarized in Table 1, includes the results of 73 diamond drill holes (9,597 metres ("m") and 43 reverse circulation ("RC") holes (2,249 m). Due to the timing of the Estimate, it does not incorporate the analytical results for three diamond drill holes (489 m) from the 2011 drilling program.

RESOURCE ESTIMATE HIGHLIGHTS

The reader's attention is drawn to the following Canadian Institute of Mining and Metallurgy ("CIM") definitions:

'Inferred Mineral Resource' is that part of a Mineral Resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.

An 'Indicated Mineral Resource' is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confidence sufficient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.

NI 43-101 requires it to be stated that mineral resources that are not mineral reserves do not have demonstrated economic viability.

The Estimate was prepared by ACA Howe and MCS and has an effective date of January 9, 2012. Contributors to the preparation of the Estimate included Mr. J.N. Hogg MSc., MAIG, Senior Geologist with MCS and Mr. L. McGarry BSc., FGS, Geologist with ACA Howe. Inputs for economic cut-off calculations for resource reporting were prepared by Mr. B. S. Brady, P.Eng., Senior Associate Mining Engineer with ACA Howe, in consultation with his senior colleagues.

At Shirotnaia, mineralization occurs within three main east-northeast trending structural zones, namely North, Central and South.

In the North zone corridor, resources are defined within discreet steep northeast dipping structures in four sub-zones over a 2.0 kilometre ("km") strike length, to maximum depth of approximately 200 metres below surface ("mbs"). Mineralized zones are open along strike and at depth, with evidence of continuation of mineralization indicated by trench and shallow rotary air-blast drilling ("RAB") drilling. Within the 2.0 km strike length a 400 m section between northwest and northeast domains remains untested, offering significant potential for further immediate resources.

In the Central zone, resources are defined within discreet moderate to steep northeast dipping structures over a 1.2 km strike length, to a maximum depth of approximately 200 mbs. Mineralization is open along strike and at depth, with evidence of continued mineralization indicated from trenching and shallow RAB drilling.

In the South zone, resources are defined within shallow northeast dipping structures in three sub-zones over a 1.1 km strike length to a maximum depth of approximately 150 mbs. Mineralization remains open along strike and at depth. An untested area of 300 m strike length between west and east mineralized domains offers significant immediate resource potential.

The in-situ gold mineralization at Shirotnaia is hosted in a sequence of mostly andesitic volcanic and volcaniclastic rocks with rare sediment horizons. There is an oxidized zone 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. Due to the various styles of gold mineralization, ACA Howe estimated natural cut-off grades for the oxide and primary styles of gold mineralization.

ACA Howe and MCS completed studies according to NI 43-101 and best practice guidelines. Resource modeling and estimations being completed used the industry accepted Micromine 2012, 3d modeling software package.

Indicated category resources are reported to be contained in oxide, transitional and primary material. Of the 645,000 ozs in the Inferred resource category, 137,000 ozs (21%) are reported to be contained in the oxide material. Primary material accounts for 414,000 ozs (64%) while the remaining 93,000 ozs (15%) is transitional material.

Shirotnaia mineralization comprises multiple structurally and lithologically controlled mineralized zones. Thirteen mineralized in-situ domains were modeled for this Estimate each comprising oxide, transitional and primary material types.

For this Estimate, grade interpolation was performed using the inverse distance weighted method. Resources are reported using an economic marginal cut-off, determined by use of simple block revenue factor methodology and a two year trailing average gold input price.

Tables 2 and 3 as noted below set out the Shirotnaia Estimate for oxide, transitional and primary gold material types by category and material type as reported by ACA Howe and MCS at block revenue calculated cut-offs and selected cut-off of 0.5 g/t Au.

Based on the geological model, exploration grid, search ellipsoid ranges, composite sizes and mining method, the data used in the Estimate was block modeled with a block size of 10 m x 10 m x 10 m for the in-situ mineralization and sub-blocking to 2 m x 2 m x 2 m was performed to achieve accuracy along domain wireframe boundaries.

Following statistical analysis of domain input Au sample data, top cuts of 5 g/t Au were applied to three mineralized domains, 10 g/t Au to three mineralized domains and 15 g/t Au to one mineralized domain. Input sample data were composited to 1 m intervals for all zones.

As of January 31, 2012 the gold mineralization at Shirotnaia remains open to the north, northeast and southwest as well as at depth.

Saga Creek Gold Corporation LLP ("Saga Creek"), a 100% owned subsidiary of the Corporation, is responsible for the exploration activities conducted on Shirotnaia. Saga Creek employs approximately 320 people in its exploration and mining related activities and contributes significantly to the local economy.
