Vancouver — Initial drilling by Bell Resources (BL-V, BZRSF-O) on its Sombrero Butte project in Pinal Cty., Ariz., has delivered a wide copper-mineralized interval.
Hole SB-02 intersected 48 metres (from 286 metres down-hole depth) averaging 1.06% copper, including a 10-metre section of 2.04% copper in the Magna breccia pipe. The hole also cut zones of porphyry intrusives, forming sections of the breccia matrix, supporting the company’s hypothesis of a possible underlying porphyry copper system.
The breccia pipes exhibit oxidized and leached caps near surface, with an underlying supergene copper enrichment zone containing chrysocolla and chalcocite mineralization.
Bell’s land position at Sombrero Butte consists of about 2.6 sq. km in the Copper Creek district and is the first time the claim package has been consolidated since mining started there in the 1920s. The project consists of a cluster of almost 20 copper-bearing breccia pipes where the company is targeting a potential 10 to 20 million tonnes of higher-grade (1.5% to 2.5%) copper mineralization in the breccias with a possible underlying, large tonnage copper-porphyry system.
Based on its initial results, Bell’s planned drill program has been doubled to about 3,000 metres to more thoroughly test additional breccia pipes and is expected to carry into early 2007.
