New 21st Century Copper Mine Planned for Central Montana


BILLINGS, MT (November 9, 2015) – Tintina Resources Inc. is a Vancouver, British Columbia, Canada based resource company focused on the development and mining of its 100{257ecae47c7fec349321aca28547072fa2160c1991a573be7695613338f0f130} owned flagship property, the Black Butte Copper Project in central Montana. The Black Butte Copper Project is one of the highest grade copper projects in North America.

Tintina is led by a highly experienced executive management team that has an impressive track record of successfully building shareholder value through exploration, corporate finance and mine development.

The Black Butte Copper Project is located approximately 20 miles north of the community of White Sulphur Springs in central Montana and is approximately 100 miles south from Great Falls, MT.

The Black Butte Copper property consists of approximately 12,000 acres of both long-term mining leases on private ranch lands and 100{257ecae47c7fec349321aca28547072fa2160c1991a573be7695613338f0f130}-owned federal mining claims. The property has maintained gravel road access and is within two miles of an all-weather highway. The property is also near a high-voltage power line and is 50 miles from rail service.

Members of the Northern Ag Network Team recently toured the proposed Black Butte Copper Project footprint and spoke with people on both sides of the issue. The following video was produced by the Northern Ag Network’s Russell Nemetz .

The copper-cobalt-silver deposits at Black Butte Copper occur in extensive shale-hosted bedded sulphide zones. These sulphide zones contain copper, cobalt, silver and barite, and occur at multiple levels throughout at least 750 meters of stratigraphy. Some zones show great lateral extent and some reach over 100 meters thick.


Tintina is pleased to provide an update outlining development plans for the Johnny Lee copper deposit at its flagship Black Butte Copper Project. These plans incorporate best industry practices and outline the details for management of mill tailings (finely ground rock left after copper minerals are removed) which include cementing tailings for storage both underground and in a double lined surface tailings facility. 

The Company has completed design level studies for both returning cemented tailings underground during ‘cut and fill’ mining as paste backfill, and storing the remainder of the cemented tailings in a double lined surface Cemented Tailings Facility (“CTF”). The studies also include plans for reverse osmosis (“RO”) water treatment of all site waters, including precipitation run off water that comes into contact with the CTF, no discharge of water to surface, and complete mitigation of all beneficial water use by the operation. The Mine Operating Permit (“MOP”) application scheduled for submission to the Montana Department of Environmental Quality (“DEQ”) later this year will include detailed studies in support of these designs. Explanations of these designs are available on the Tintina website ( 


The CTF design eliminates certain risks associated with the more traditionally used and industry standard sub-aqueous tailings impoundment. The Company chose this design because it provides enhanced protection of all surface and ground water and meets Montana’s non-degradation water standards for industrial activity. In addition, this design inhibits the potential for errant dust from the CTF and allows for expedited reclamation at mine closure which includes a geotextile over-liner sealed to the underlying double liner and all covered with fill and capped with top soil. The design will receive peer review under Montana’s comprehensive regulatory process, including the recently adopted 2015 legislation related to tailings disposal. The design exceeds the most stringent earthquake and storm event standards for the area.
