Seymour Exploration Corp. Unveils Exploration Targets At Lynn Lake Nickel Mine Property

Sudbury, Ontario – September 27, 2005 – Seymour Exploration Corp. (SEZ: TSX-V) is pleased to release details of diamond drilling targets for the Lynn Lake Mine property. As a result of analyzing all historic data for the mine, the Company has outlined 15 first-priority targets. These targets were identified by digitally constructing a 3-D computer model of the mine incorporating previous exploration holes. Each of the targets is characterized by widely spaced historic drill holes that intersected mineralization, but were not followed up with further drilling. Highlights of these new targets include:

• ‘Echo,’ a 1,200 foot long zone with an average of 66 feet true thickness that was intersected in 13 boreholes between the 740 foot level and the 3,180 foot level (2,440 feet). Mineralized intersects included high grade intervals of up to 2.18% nickel and 1.06% copper over 14.7 feet. ‘Echo’ is open to surface and at depth.
• ‘Golf,’ where an historic fan of seven drill holes encountered consistent mineralization including 54 feet of 1.72% nickel, 0.62% copper, as well as 75 feet of 1.22% nickel and 0.52% copper in another hole. This target is 1,600 ft wide and open at depth.

Seymour plans on initiating a diamond drilling program this fall to begin testing these targets. For the first time at Lynn Lake, borehole electromagnetic geophysics will also be used to help determine the shape, size and continuity of each of the target zones. It is expected that this technology will be highly effective in detecting and characterizing sulphide bodies in the mine environment.

The Company has developed a phase one exploration plan, which will see nine of the top priority targets tested by diamond drilling. The following table provides highlights of historic results of drilling in these areas.

The Company’s recently announced resource calculation has a high degree of confidence, as definition drilling undertaken during the operation of the Lynn Lake Mine was closely spaced. This was not the case, however, for exploration drilling. Exploration drilling was executed along developed levels, leaving up to 1,000 foot areas between levels untested. As a result, Seymour has established that approximately 50% of the host intrusion is unexplored. The Company considers any area in the geological mine environment that is greater than 300 feet from any mine opening or historic drill hole to be unexplored.

The Company’s goal is to determine the economic potential of the Lynn Lake mine. To that end, it will commission a scoping study based on the measured and indicated resource of 6.4 million tons grading 0.85% nickel and 0.39% copper (see press release dated Sept. 19, 2005).
