Columbus Copper Reports 54.0 m Grading 3.3gpt Gold from Continuous Rock Chip Sampling at its Kavaklitepe Project
11.06.2013 | Marketwire
VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 06/11/13 -- Columbus Copper Corporation ("Columbus Copper") (TSX VENTURE: CCU) (formerly Empire Mining) is pleased to provide additional exploration results from its 100% owned Kavaklitepe gold project in western Turkey. Continuous rock chip sampling along a forest track running across one of the mineralized zones returned 54.0 metres grading 3.33 grams per tonne ("gpt") gold including 21.5 metres grading 7.2 gpt gold where the mineralization is better exposed and no contamination with overburden was observed. Scattered rock chip composite samples were also collected within the zone and returned 22.7 gpt, 13.2 gpt and 1.91 gpt gold respectively, and confirm previously announced positive gold results. The gold mineralization was found within a well-defined soil anomaly that measures 850 metres by 250 metres elongated northeast to southwest, that might be displaced about 700 metres by a northwest-trending fault, and continuing for another 800 metres to the southwest. The limited outcrop found and sampled within the zone led to identify brecciated schist with dark silica infill suggestive for a low-sulphidation epithermal type of gold mineralization.The results from the rock chip sampling are presented in the table below together with the original reconnaissance rock sampling by Columbus Copper that was reported in news releases of January 17, 2013 and March 1, 2013 respectively. Results from the current sampling are highlighted in grey.

The two previously reported soil sampling areas that returned open gold anomalies in all directions have now been extended and connected by additional 512 soil samples collected in a 50 metre x 50 metre grid. The new sampling brings the total number of soil samples collected on the project, including standards and field duplicates to 1,583 of which 176 return gold grades higher than 50 parts per billion ("ppb"), 70 - higher than 100 ppb and 40 - higher than 250 ppb with 5 of these samples containing more than 1000 ppb (1 gpt) gold.
Columbus Copper reported the discovery of gold mineralization at Kavaklitepe in a news release dated January 17, 2013. The discovery was made by following up a stream sediment anomaly and resulted in an average of 2.67 gpt gold over 21 metres of exposure. Follow up on a soil sample anomaly led to identification of a brecciated zone striking 50NE with low-sulphidation epithermal gold signature at about 1.4 kilometres northwest from the discovery outcrop. Four rock samples collected there returned 28.2 gpt, 21.7 gpt, 6.7 gpt and 3.66 gpt gold respectively (see news release of March 1, 2013). The additional sampling confirmed the presence of high-grade gold mineralization returning 54.0 metres of continuous rock chips with an average grade of 3.33 gpt gold and delineated a mineralized zone measuring 850 metres by 250 metres. The zone is possibly displaced by a northwest southeast trending fault at its southern margin, but possibly continues for another 800 metres to the southwest where gold grades are strongly anomalous.
Columbus Copper's Kavaklitepe Project is situated 120 kilometres south-southeast of Istanbul in western Turkey, immediately north of a fertile zone demonstrating copper, molybdenum and gold porphyry systems. A set of dominantly dextral strike-slip and cross sinistral faults have been interpreted to form extensional strain anomalies and pre-mineral shear zones and folds in the area. The dextral faults are also parallel to the Eskishehir Fault that is regionally important and is considered to penetrate deeply into the Earth's crust and probably controls the emplacement of the two known porphyry systems in the area.

Columbus Copper plans to open up trenches where the soil anomalies are defined and conduct orientation IP geophysics. A shallow drill-hole campaign is also intended once the follow-up has been completed.
Quality Assurance/Quality Control
All soil sampling was carried out according to procedures described in the Bursa CPR and comprise 'B' horizon soils sent under chain of custody to ALS Chemex in Vancouver after preparation in ALS' preparation facilities in Izmir, Turkey. In addition to the 512 soil samples, 27 standard reference materials and 25 duplicates were included in the sample batch.
All rock samples were sent under chain of custody to ALS Chemex in Vancouver after standard preparation in ALS' preparation facilities in Izmir, Turkey. Rock samples were analysed for gold by the ALS Au-AA25 method, while multi-element geochemistry was done by the ALS ME-ICP61 method, determining 33 elements. The rock sample batches included 2 standard reference materials.
All standard reference material samples for both soil and rock samples reported within their respective certified ranges.
In addition, ALS Chemex performed internal check assaying on about 5% of the samples, and also included analyses of internal standards inserted into the sample string.
