White Sulphur Springs, MT – September 19, 2016 – Tintina Montana Inc. (“Tintina” or the “Company”) is pleased to announce that it has submitted responses to questions from the Montana Department of Environmental Quality (DEQ) in regards to the underground Black Butte Copper Mine Operating Permit application (“MOP”). This thorough review of the MOP includes detailed studies by third party consultants which have been peer reviewed to ensure the most robust and complete application possible.
A summary of the proposal can be found on our website http://blackbuttecopper.com along with a 3D animation of the planned project showing what the site will look like before and during mining operations as well as after reclamation.
Key aspects of the original MOP remain unchanged and are designed to protect the Smith River Watershed:
- All openings and entry point to the mine (including underground vent raises) will be located well above the water table to prevent water from ever leaving the mine.
- Ground water from the mine will receive reverse osmosis water treatment before being returned back to the ground water system through an underground infiltration system. No surface water will be used during mining.
- A reverse osmosis water treatment plant will treat water on-site from construction through reclamation and will remain as long as it’s needed to ensure all water involved in the operation will meet Montana’s non-degradation water standards in reclamation and closure.
- Our mining plan fills all mined areas with cemented mill tailings (finely ground rock left after removal of copper minerals). This way, only a small percentage of underground mine is open at any given time during mining. There will be no large open spaces left underground and thus no possibility of underground water reserves or surface subsidence.
- Mill tailings that are not returned underground (approx. 55%) will be cemented, and will harden in a double-lined surface facility. This innovative use of existing mine technology eliminates any need for a tailings pond, eliminates windblown dust and prevents acid runoff. All unmilled rock brought to the surface will also be stored in this facility.
- During reclamation, the cemented tailings facility will be sealed with another liner, covered with several feet of cover and original top soil. After reclamation the entire site will be returned to the traditional use of cattle grazing.
John Shanahan, CEO stated, “I want to thank the Montana Department of Environmental Quality for their professional and thorough approach. Our application is now more comprehensive because of the excellent questions posed by the DEQ. We look forward to working with the department as they continue the review process through the Completeness and Compliance phase of permitting.”
Jerry Zieg, VP of Exploration closed by stating, “This is where I grew up, so I am proud to be part of a project that successfully protects traditional uses of our watershed, fits well in my community and safeguards the environment; all while providing tremendous economic opportunities for Central Montana. Our highly engineered plan and quality design is one that Montanans and the mining industry can be proud of.”
