Montanore Project Receives Sentinels of Safety Award

Spokane, Washington - November 21, 2011 -  Mines Management, Inc. (NYSE-Amex:
"MGN", TSX: "MGT") (the "Company") is pleased to announce that its Montanore
Silver-Copper Project has been awarded the Sentinels of Safety Certificate of
Achievement in Safety for the calendar year 2010.  Montanore Minerals
Corporation, the Company's wholly owned subsidiary, received the state award for
outstanding safety performance in the category of small underground metal mines
in the Rocky Mountain District.  Additional information regarding Mines
Management, Inc., and the Montanore Silver-Copper Project may be obtained at the
Company's website at:www.minesmanagement.com.

Certificates of Achievement in Safety are awarded to participating operations
that have met all of the award criteria as established by the Mine Health and
Safety Administration ("MSHA") and the National Mining Association.

The Company's President and CEO, Mr. Glenn M. Dobbs, stated, "We are grateful
for MSHA's recognition of our efforts to create a safe working environment at
our operations.  Montanore employees have completed significant work already
with 7,200 feet of underground rehabilitation and dewatering in the Libby
Evaluation Adit, as well as construction of infrastructure and surface
facilities at the site.  We will continue to focus on excellence to set a strong
foundation for not only safety, but also environmental stewardship, community
responsibility, and operational efficiency as we advance the Montanore through
the permitting phase toward development."

Sentinel of Safety Award

The annual Sentinels of Safety award program recognizes achievement of
outstanding safety records, to stimulate greater interest in safety and to
encourage development of more effective accident prevention programs among the
Nation's mineral extractive industries.  This program is co-sponsored by the
MSHA and the National Mining Association.  All active and intermittently active
mineral mining operations required to report injury and employment data under
the Federal Mine Safety and Health Act of 1977 are eligible to participate.  Ten
separate groups consisting of mining operations having similar characteristics
are identified for the program.  They are:  underground coal mines, surface coal
mines, coal processing facilities, underground metal mines, underground nonmetal
mines, open pit mines (metal and nonmetal except stone), open pit stone
quarries, sand and gravel bank or pit operations, sand and gravel dredge
operations, and metal and nonmetal mills.  Each of the groups are further
divided into large and small mine categories resulting in a total of twenty
separate groups.  The median hours worked at all mines in each group will
determine eligibility in the large and small categories.  The median hours
worked will define the upper limit for the small mine categories.

Mr. John E. Thompson, the Company's Vice President of Operations and General
Manager at the Montanore Project, stated, "Receiving the Sentinels of Safety
Certificate of Achievement Award is recognition for the hard work and dedication
of our outstanding employees at the Montanore Project site.  I want to thank
each employee for their part in achieving this award.  The award reflects the
successful pursuit of a culture of safety as the top priority at the Montanore
site and throughout the Mines Management organization."

To be eligible for an award, a mining operation must have reported employment
data to MSHA for each quarter in the calendar year, not experienced a work
injury that resulted in a fatality, permanent disability, restricted work or
days away from work greater than the national average and accumulated at least
4000 employee hours during the calendar year.

About Mines Management

Mines Management, Inc. is engaged in the business of acquiring and exploring,
and if exploration is successful, developing mineral properties containing
precious and base metals.  The Company's primary focus is on the advancement of
the Montanore silver-copper project located in northwestern Montana.  The
Montanore is an advanced stage exploration project, which contains a Canadian
NI43-101 compliant resource of approximately 81.5 million tons of material with
average grades of 2.04 ounces silver per ton and 0.75% copper, in the measured
and indicated category, plus an inferred resource of 35.1 million tons with
average grades of 1.85 ounces silver per ton and 0.71% copper.

Cautionary Note to U.S. Investors concerning estimates of Measured, Indicated
and Inferred Mineral Resources:
This press release uses the terms "Measured Mineral Resources," "Indicated
Mineral Resources" and "Inferred Mineral Resources."  We advise U.S. investors
that while those terms are recognized and required by Canadian NI 43-101, the
Securities and Exchange Commission does not recognize them.  U.S. investors are
cautioned not to assume that any part or all of the mineral deposits in these
categories will ever be converted into mineral reserves.  Inferred Mineral
Resources have a greater amount of uncertainty as to their existence and as to
their economic and legal feasibility.  In accordance with Canadian rules,
estimates of Inferred Mineral Resources cannot form the basis of feasibility or
other economic studies.  U.S. investors are cautioned not to assume that part or
all of the Inferred Mineral Resources exists, or is economically or legally
mineable.  Disclosure of "contained ounces" in a Mineral Resource is permitted
under Canadian regulations, however, the SEC normally only permits issuers to
report mineralization that does not constitute 'reserves' by SEC standards as in
place tonnage and grade without reference to unit measures.  Accordingly, the
information contained in this press release may not be comparable to similar
information made public by U.S. companies that are not subject to NI 43-101.
