The Black Butte Copper Project is located in central Montana and owned by Tintina Resources. The project comprises three main horizons of copper-cobalt mineralization, which are hosted in Proterozoic sediments of the Belt Supergroup. The deposits are thought to have formed near seafloor hydrothermal vents during the deposition of the host shale.

At April’s MineQuest-Tucson, long-time MineSight user, Mike Lechner of Resource Modeling Inc., explained how the software is being used to model Black Butte’s copper-rich zones. RMI elected to use a variation of relative elevation modeling in order to select eligible drillhole composites, which were used to estimate block grades. This method minimized grade smoothing and preserved the distinct synsedimentary geometry of the high-grade copper-cobalt mineralization that was deposited near the hydrothermal vents.
A Preliminary Economic Assessment was completed in late 2012 by Tetra Tech and several other consulting groups. An Expanded PEA is anticipated to be completed in the second quarter of 2013.
