For Immediate Release

Black Butte Copper Project Achieves Major Milestone-

Advances into Next Step of the Permitting Process after Receiving Complete and Compliant

Notification

White Sulphur Springs, Montana– August 14, 2017 – Tintina Resources, Inc.

(“Tintina” or the “Company”) is pleased to announce that it has received notification

from the Montana Department of Environmental Quality (“MT DEQ”) that the Black Butte

Copper Mine Operating Permit (“MOP”) is now considered to be Complete and Compliant

in accordance with all state rules and regulations relating to the operating plan of its

proposed underground copper mine in Meagher County, Montana.

The permitting process now moves to the development of a comprehensive Environmental

Impact Study (EIS). The selection of an independent and third party EIS contractor and

issuance of a draft Mine Operating Permit are in the final stages and the EIS is expected to

commence within the next 30 days. The EIS process, scheduled to take approximately

twelve months, will include public input through the public comment process and will be a

comprehensive analysis of project alternatives as required under the Montana

Environmental Policy Act (”MEPA”). In addition, the Company is required to obtain other

state operating permits including a Montana Pollutant Discharge Elimination System

(MPDES) permit, an Air Quality permit, and a Public Water Supply permit. The Company

will also complete a Hard Rock Mining Impact Plan as required by Montana statute. A

Federal Clean Water Act 404 permit is also currently in process. Upon completion, the

Company’s goal is that the EIS will result in a Final Record of Decision allowing

construction and development of this underground mine on private ranch land in Meagher

County.

A summary of the MOP can be found on our website www.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. The proposed underground mine,

located 15 miles north of White Sulphur Springs, is designed to provide economic

opportunity to Central Montana while fully protecting the Smith River Watershed:

 All designed openings and entry points to the underground mine are located well

above the water table.

 Surface irrigation rights have been leased for instream flow to ensure there is no

change to the water levels in Sheep Creek.

 A reverse osmosis water treatment plant will treat water on-site from construction

through reclamation, and will return clean water back to the same ground water

system through a buried infiltration system. The water treatment plant will remain

active as long as needed to ensure all water involved in the operation meets

Montana’s strict non-degradation water standards through reclamation and closure.

 Our mining plan fills all underground mined areas in the copper deposit with paste

backfill ensuring that only a small percentage of the underground mine is open at

any given time and that no large open spaces are left underground.

 Mill tailings that are not returned underground (approx. 55%) have cement added to

them and will be placed in a double-lined facility. This innovative use of existing

mine technology eliminates windblown dust and prevents acid runoff. Any un-

milled rock brought to surface will be stored here. During reclamation, the

cemented tailings facility will be sealed with another liner, covered with several

feet of cover and original top soil and returned to grazing.

 Our reclamation plan returns the entire site to agricultural and cattle grazing with

no treatment of water in perpetuity necessary.

John Shanahan, CEO stated, “This has been a long and involved process, and we now can

clearly demonstrate that the development and operation of this state-of-the-art project

meets and exceeds all state rules and regulations. Our objective is very clear; to

responsibly develop this project and provide both economic opportunity and complete

protection of the environment. The ongoing support and vision of our major shareholder,

Sandfire Resources, along with the unwavering support of White Sulphur Springs and

surrounding communities has made this all possible. We also gratefully thank the Montana

DEQ for their thorough and exacting review.”

Jerry Zieg, VP of Exploration closed by stating, “This is a real milestone for Tintina, the

Black Butte Copper Project, and the residents of Meagher County and surrounding

counties. Everyone has worked diligently for years, both managing and carrying out

extensive supporting studies, and communicating their constant and strong support for the

project. The Tintina team, both staff and third party contractors, are leading the world in

showing how to build a mine which will exceed regulations at all levels in true

comprehensive environmental protection while providing a much needed economic boon

to the state of Montana. All of us can be very proud of this accomplishment.”
