Jul. 26, 2011 (Marketwire Canada) --
CALGARY, ALBERTA -- Alhambra Resources Ltd. (TSX VENTURE:ALH) ("Alhambra" or the "Corporation"), an international gold producer and explorer, announces that a rotary air-blast ("RAB") drilling program completed in 2010 at its 100% owned Zhanatobe project area ("Zhanatobe") has resulted in the discovery of two possible "Carlin-style", zones of gold mineralization. Zhanatobe is one of Alhambra's 2011 early stage exploration targets within the Corporation's 100% owned, 2.4 million acre, Uzboy Project located in north central Kazakhstan (see Figure 1). Zhanatobe is located approximately 90 kilometres ("kms") southeast of Alhambra's Uzboy gold deposit and 40 kms northwest of the City of Stepnogorsk, Alhambra's Kazakhstan operating base.
- The RAB drilling program discovered two possible Carlin-style zones of gold mineralization – one in the Central area and the second in the Northern area (see Figure 2),
- The mineralization exhibits many similarities to sediment hosted disseminated style gold mineralization in Nevada ("Carlin-style" gold mineralization) which is completely new for the region,
- The zone of gold mineralization discovered in the Central area is approximately 850 metres ("m") in length and 100 m in width,
- The zone of gold mineralization discovered in the Northern area is approximately 400 m in length and 150 m in width and open on both ends,
- Gold grades range from 0.10 to 1.72 grams per tonne gold ("g/t Au") in the Central zone and from 0.19 to 0.51 g/t Au in the Northern zone,
- As a result of the positive 2010 drilling results, the Corporation has updated and expanded its anticipated 2011 core, RC and RAB drilling program for Zhanatobe to approximately 12,000 m.
John J. Komarnicki, Alhambra's Chairman and Chief Executive Officer stated, "This is a very exciting development at Zhantobe. We have discovered two possible Carlin-style zones of gold mineralization, which suggests that we may have located a new very large, prolific area of gold mineralization. As a result, we anticipate implementing a more aggressive 2011 drilling program including deeper, more precise core drilling, with the objective of reclassifying Zhanatobe from early exploration status to advanced exploration status in 2012."
The objective of the 2010 exploration program at Zhanatobe was to determine the nature of the gold mineralization established in 2009 by rock chip sampling and to check for gold mineralization at shallow depth. Fifteen lines of RAB drilling amounting to 483 drill holes totaling 4,744 m were completed in both the Northern and Central areas of Zhanatobe (see Figure 2).
Drilling to date has resulted in the discovery of a zone of gold mineralization of a new style, in the Central area (see Figure 3). This new ENE orientated zone has confirmed the presence of gold mineralization along a strike length of approximately 850 m and is up to 100 m in width with gold grades ranging from 0.10 to 1.72 g/t Au. Hole JT-0518 intersected four, 2 m long samples that returned 1.69, 1.72, 0.89 and 0.22 g/t Au, respectively. This zone is interpreted to be related to the contact of a silicified body with sandstone, calcareous sandstone and epiclastic sandstone host rocks.
Previously interpreted drilling results led to the discovery of the second zone of gold mineralization in the Northern area with a strike length of 400 m and a width of 150 m with gold grades ranging from 0.19 to 0.51 g/t Au (see Figure 4). The zone trends ENE and corresponds with a silicification and brecciation zone at the contact between calcareous and epiclastic sandstone and siltstone horizons.
The district scale geology is characterized by the presence of calcareous and terrigenous sediments intruded by granitoid massifs, collapse breccias and barren jasperoid caps on the top of the sequence. It appears that there is sediment hosted, fine grained disseminated gold, accompanied by de-calcification and brecciation, a spatial link to granitoid intrusions, strong silicification expressed as jasperoid, the secondary mineral jarosite and, as indicated by the rock chip sampling program, high Ag and strongly elevated As and Sb.
All this leads Alhambra to believe that the two discovered zones of gold mineralization may be Carlin-style in nature, named after the Carlin Mine on the Carlin Trend in Nevada (USA). Carlin-style gold mineralization has not been previously recognized in Northern Kazakhstan but has generated a significant percentage of the world's gold production.
Mapping and surface rock chip sampling carried out in 2009 outlined two very large zones measuring 12 kms by 3 kms and 10 kms by 2 kms with a high density of anomalous gold concentrations (above 70 parts per billion gold ("ppb Au")) in volcano-sedimentary rocks. There are several clusters of higher (+0.1 g/t Au) grade rock chip samples inside both anomalous zones. Two of them, the Northern and Central areas, look the most prospective, demonstrating not only high peak grades (34.4 g/t and 11.5 g/t Au respectively, reported previously) (see News Release dated May 17, 2010) but also consistent spatial distribution of the rock samples grading more than 0.1 g/t Au.
In the Central area, the exploration drilling program on 8 drill lines comprised 291 vertical RAB holes totaling 2,850 m. Six drill lines from 400 to 1,000 m long, spaced 200 m apart, were located in the northern and southern parts of the Central area. Each hole was about 10 m deep and one sample was taken from the bottom of the hole. Two additional RAB lines, 370 and 500 m long with closer hole spacing were drilled in the northern part of the Central area to test its geologically most promising part where a silicified body was discovered. These holes were also 10 m deep but in this case the entire hole was sampled in 2 m intervals (as per hole JT-0518).
In the Northern area, 192 vertical RAB holes were drilled totaling 1,900 m on 7 drilling lines ranging in length from 600 to 700 m, spaced 200 m apart and located in the northern, central and southern parts of the Northern area. Each hole was about 10 m deep. One sample was taken from the bottom of the hole.
Based on these positive 2010 Zhanatobe RAB drilling results, the Corporation has updated and expanded its anticipated 2011 exploration drilling program for Zhanatobe to approximately 12,000 m. This will be a sequenced drilling program with 856 RAB holes, 17 RC holes and 5 core holes. The objective of the drilling program will be to test other prospective areas of the project, determine the shape and size of the discovered zones of mineralization, prove the mineralization style, and most importantly, define gold grade at depth.
DRILLING AND SAMPLING PROCEDURES
Rotary Air Blast or RAB drilling is a type of compressed-air driven percussion drilling used in the early phases of mineral exploration for a quick assessment of a relatively large area which normally precedes deeper, more precise Reverse Circulation or RC percussion drilling and core drilling.
The drilled RAB holes had a 7.6 centimeter diameter. The cuttings from the interval sampled in each hole were mechanically split into two samples. The samples selected for analysis were placed in a cloth bag and weighed at the drill site. The weight of the samples ranged between 5 and 7 kilograms. Based on sample weight, the recovery from the holes is estimated to be almost 100%.
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 with atomic absorption finish. Stewart Assay and Environmental Laboratories is independent of Alhambra and has 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.
