August 30, 2005
Press Release
SPOKANE, Wash -- August 30, 2005 -- Mines Management, Inc. (AMEX: MGN) announces financial results for the second quarter.

Mines Management, Inc. reported a net loss for the quarter ended June 30, 2005 of $1,118,794, or $0.10 per share versus a loss of $239,483, or $0.02 per share for the prior year’s quarter ending June 30, 2004. The increase in net loss for 2005 of $879,311 was due to an increase in activity on the Montanore Project for environmental, engineering, and permitting expenses.

For the six months ended June 30, 2005 the Company had a net loss of $2.3 million, or $0.21 per share compared to a net loss of $1.8 million, or $0.19 per share for the same 2004 period. The increased loss for the year is attributable to the increased activity and expenses for the Montanore Project, and fewer options granted in the 2005 period than in the 2004 period; plus there was no financing activity through the second quarter 2005 offsetting 2004 fees. Administrative expenses increased as a result of greater outlays for investor relations and compensation as a result of hiring additional employees.

For the quarter ending June 30, 2005, net cash used for operating activities was $776,260, most of which was attributed to permitting and engineering expenses for the Montanore project. This amount was offset by proceeds from the exercise of warrants for the period of $511,518. The net decrease in cash for the second quarter was $301,156. Year to date, net cash used was $916,677.

It is anticipated that expenditures will continue to increase through the end of 2005 as the company moves through re-permitting, feasibility, and development of the Montanore Project. The Company expects to spend approximately $1.0 million per quarter for the remainder of the year 2005.
