  Mines Management Inc.: Mines Management Inc. Corrects the Record Regarding
                             Montanore Litigation

Spokane, Washington - June 18, 2014 -- MINES MANAGEMENT, INC, (NYSE-MKT:  MGN, 
TSX: MGT)  ("MMI" or  the "Company"),  is issuing  this statement  to  provide 
accurate information to the public  and shareholders of the Company  regarding 
recent federal and state court  rulings in litigation involving the  Company's 
Montanore project, and to correct recent incorrect and misleading reports  and 
statements in various publications by third parties.

As previously reported, the Company has  been involved in disputes in  Montana 
state and federal  courts regarding  unpatented mineral  claims located  above 
portions of  the  Libby Adit  which  provides underground  access  toward  the 
Company's Montanore  deposit, and  overlapping certain  of Mines  Management's 
patented claims, mill sites and tunnel sites.

MMI received favorable rulings earlier this year in both the state and federal
lawsuits pertaining to the Montanore project. In January, the Montana Supreme
Court reversed a March 2013 state district court ruling on the validity of the
unpatented mineral claims, now owned by Optima Inc., by vacating an injunctive
order due, in part, to faulty reasoning and lack of evidence.

In addition, based upon  a June 2013  lawsuit filed by  the Company, the  U.S. 
District Court  in Missoula  (1) granted  in March  2014, MMI's  motion for  a 
preliminary condemnation  order giving  MMI an  easement through  the  alleged 
unpatented mineral claims controlled by  Optima; and (2) issued an  injunction 
to prevent interference with MMI's use of the Libby Creek adit.

The federal court ruling confirms the  Company's ongoing unimpeded use of  the 
Libby Adit, which we have continued to maintain in accordance with our current
operating permit.

The subject claims  were acquired  from previous  holders by  Optima, Inc.,  a 
Montana corporation formed in 2013. According  to filings with the State  of 
Montana, Optima's board of directors includes Mr. Frank Duval and his daughter
Heather Duval Ennis,  former Montana Governor  Brian Schweitzer who  currently 
serves as Board Chairman of Stillwater Mining (NYSE-MKT: SWC), Vancouver stock
trader and  V.P. with  Haywood Securities,  Mr. David  Elliott, and  a  former 
official with the U.S. Forest Service minerals division, Mr. Bruce Ramsey.

Mr. Glenn Dobbs, the Company's chairman and CEO, stated, "Mines Management  is 
vigorously responding to Optima on all fronts, including in the courts. Among
other things, the Company has filed a motion to strike Optima's demand for $10
million as compensation for  MMI's successful condemnation of  a right of  way 
through Optima's  asserted claims.  We believe  that Optima's  claim for  $10 
million is frivolous  because it attempts  to establish value  based upon  the 
wrong measure, not in accordance with the law, and we are confident our  legal 
initiatives will continue to be successful."

Mines Management owns 100%  of a large  silver/copper deposit in  northwestern 
Montana. According  to public  filings, the  Montanore project  contains  at 
least 81.5 million tons  of mineralized material with  average grades of  2.04 
ounces  silver  per  ton  and  0.75%  copper.  A  2011  preliminary  economic 
assessment listed the pre-tax  net present value of  the project at more  than 
$400 million.

Libby, Montana, is a small town of approximately 3,000 people and about 15,000
people in the immediate county. The area  has been hit hard by the  recession 
and loss of its logging industry  to environmental activism and, as a  result, 
has an unemployment rate of about 15%. A mine at the Montanore project  could 
create 350 new direct jobs in this small community.
