Seymour Exploration Receives Positive Signal from Manitoba Government

Sudbury, Ontario – September 8, 2005 – Seymour Exploration Corp. (TSX-V: SEZ) announced today that as part of registering the Company’s ownership of the Lynn Lake nickel mine property, the Manitoba Government has confirmed that Seymour and its subsidiary Lynn Lake Nickel Mining Company will not incur liability for existing site contamination. In reaching this conclusion the Manitoba Department of Industry, Economic Development and Mines conducted extensive research into the history of ownership and liability for in situ contamination resulting from former mining operations.

Commenting on this positive development, Richard Murphy President and CEO of Seymour Exploration stated “We are very pleased with this decision, which demonstrates responsible leadership on the part of the Manitoba Government. Since January 2005, we have been working closely with the Department and are impressed with their efforts to clarify the complex history of site ownership and liability. This establishes a framework for future resource development at Lynn Lake and clears the way for us to begin exploration and resource expansion at the former mine site.”

Seymour Exploration Corp.’s objective is to establish the existing mineral resource in the Lynn Lake nickel mine and add new resources through exploration so that the economics of reopening the mine can be determined. The Company expects to release the results of the ongoing resource calculation in the second half of September.
