Mines Management, Inc. (NYSE Amex:MGN) (TSX:MGT) (the “Company”) is pleased to announce completion of a study to monitor the grizzly bear in the Montanore project area, which is located in a portion of the Cabinet/Yaak Ecosystem recovery area. The study utilized technologically advanced sampling methods that included DNA analysis, and seeks to assist with monitoring and mitigation efforts to understand and support the health of the grizzly bear population.

During the summer of 2009, scientists from the University of Washington and Kline Environmental Research were contracted by the Company to conduct a study in and around the Montanore Project area to assess the current condition of the grizzly bear population using DNA analysis of grizzly bear scat.

From the results of the study, a number of conclusions were reached, including the following:
  • There are very likely significantly more grizzly bears in the Cabinet Mountains than has been previously reported.
  • Either through augmentation or transient bears, the region may be at a stable condition and at its natural carrying capacity for grizzly bears.
  • Current grizzly bear management activities in the recovery area should be reviewed due to recent grizzly mortalities and the increase of bears leaving the recovery area.
  • DNA studies can identify individual grizzly bears from collected scat samples, which can be used to assess habitat and numbers of bears in the study area. The method proved to be an effective, non-intrusive method for monitoring grizzly bears, as compared to radio collars or hair sampling.


As part of its environmental review process and its extensive efforts to minimize the Montanore project’s impact to the environment, the Company has proposed measures to protect and monitor local threatened species, including the grizzly bear.

As part of its activities to develop effective monitoring methods, the Company engaged the University of Washington to implement and test a grizzly bear monitoring program. The collection of data included the use of specially trained dogs to detect and locate bear scat in the approximately 675 square kilometer sample area in an around the Cabinet/Yaak Ecosystem. Recently concluded testing and analysis of the data found that a larger and more diverse population of grizzly bears is likely to exist in the region than previously reported.

Results of the study are very important and can assist government wildlife agencies in the development of an effective mitigation program that reflects the current state of health of the grizzly bear population in the region of the project, and can assist them in achieving their stated goal for sustainable recovery of a population of grizzly bears. The study also provides a new and better understood baseline for the current population and health of the grizzly bear in the region.

Mr. Glenn Dobbs, the Company’s President and CEO, stated, “We are pleased that recent results of the study show an improved population of grizzly bears in the Cabinet/Yaak recovery zone. The method of analysis has been demonstrated to be highly effective at better understanding the health and population of the bears, and will assist our efforts to develop a management plan to further stabilize the grizzly bear in northwest Montana. As the Montanore project approaches development, we look forward to assisting with this management effort over the long term.”

The Montanore project is a large underground silver and copper mineral project which, if approved, could employ more than 300 permanent workers for the life of the mine.
