Tintina Resources, a Canadian junior company headquartered in Vancouver, has announced a new resource estimate for the Lowry deposit on its 100%-owned Black Butte copper project located about 100 km south of Great Falls, Montana, USA. When combined with a previously announced resource of the Johnny Lee deposit, the two deposits give the project a measured and indicated resource of 1.18 billion lb of copper at a grade of 3.4% copper and an inferred resource of 140 million lb of copper at a grade of 2.8% copper. The resource also includes cobalt and silver values.

Tintina has completed more than 54,500 m of drilling at Black Butte since September of 2010 and has based its resource estimates on this drilling as well as on about 37,500 m of historic drilling. At least five additional copper mineralized zones have been identified in the resource area.

Tintina is working on an updated preliminary economic assessment of the Black Butte project that will include the resources of both the Johnny Lee and Lowry deposits, with completion of the study expected by the end of the second quarter of 2013. The company has submitted an application for an exploration decline to the Montana Department of Environmental Quality, with approval expected during the second quarter of 2013.
