Proposed Black Butte Copper Mine in Meagher County

Metal Mines Reclamation Act (MMR) Information

Tintina Resources submitted on December 15, 2015 an application with the Department of Environmental Quality for a Mine Operating Permit for an underground copper and related minerals mine in Meagher County in west-central Montana.

The proposed mine is approximately 20 miles north of White Sulphur Springs, the Meagher County seat. The deposits lie within the Belt Supergroup, an extensive sedimentary formation that extends from central Montana into northern Idaho.

In 2010, Tintina (formerly Mantra Alaska Exploration) applied for an exploration license to conduct core drilling on the Black Butte Project. This work was approved under Exploration License #00710 and bonded accordingly. Since then, several rounds of core drilling have been conducted under amendments to the license and have further defined the extent of the mineralization in the project area. The drill holes have also been used for an aquifer pump test which provided hydrologic information of the Belt Supergroup rocks in which the deposits are hosted.

All of the work Tintina is currently permitted and bonded for is available at DEQ's Hard Rock website
