ITEM 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year

On April 15, 2009, the Board of Directors of Mines Management, Inc. (the “Company”) approved the First Amendment (the “Amendment”) to the Bylaws of the Company (the “Bylaws”). Pursuant to the Amendment, Article II, Section 10 was added to the Bylaws to require a shareholder who seeks to present business or to nominate directors for election at a shareholders’ meeting to provide notice to the Company in advance of the meeting and to include in such notice certain disclosures about the shareholder and the business to be proposed. Article II, Section 8 of the Bylaws was amended to (a) eliminate cumulative voting rights set forth in the Bylaws to make them consistent with the Company’s Articles of Incorporation, which prohibit such voting and (b) eliminate the Bylaw provision requiring that the record date for any shareholder meeting be not more than forty (40) days prior to the date of such meeting, rather than seventy (70) days, as permitted by Section 30-1-707 of the Idaho Business Corporation Act.

The Amendment became effective upon its approval by the Board of Directors. The foregoing description of the Amendment is only a summary and is qualified in its entirety by reference to the full text of the Amendment and the Bylaws. A copy of the Amendment is attached hereto as Exhibit 3.2 and is incorporated by reference herein.
