Tintina Resources has reported the assays of 10 more holes drilled at the Black Butte copper project in USA. The company has intersected 0.11% cobalt, 2.12% copper and 11.9 g/t silver over 42.34 m in hole SC11-076, 0.14% cobalt, 2.84% copper and 24.0 g/t silver over 11.70 m and 0.10% cobalt, 1.83% copper and 18.7 g/t silver over 43.75 m in hole SC11-079.
Strawberry East Plan Map - Black Butte Copper Project
These 10-hole assays along with other previous results reported by the company have shown that high-grade mineralized copper is present in significant widths in the Strawberry East Target. The Lowry deposit, including five separate zones, is present in this Strawberry East Target. Tintina has encountered good results from the Lowry middle zone (LMZ). Sufficient data is available for commencing the LMZ resource model. The company is continuing the work to determine an Inferred Resource estimate.
This LMZ is a tabular layer and measures 500x300 m. It contains mineralization of cobalt, copper and silver. This mineralization, associated with strong, high-grade chalcopyrite, is present in a wide silicified and dolomitized, fragmental carbonate and shale region. The LMZ is present in the lower Newland shale and is located at depth that ranges from 300 to 500 m beneath the surface. The LMZ stays open towards the south.
Infill drill program has been recommenced on 12 January, 2012, at the Johnny Lee lower zone using two rigs that are present on site. This drilling has been aimed to gather adequate information to advance the Johnny Lee lower zone’s inferred resource estimate. The company is expecting to complete the in-fill drill program at this Johnny Lee lower zone on April 1, 2012.
