St. Eugene Intersects High Grade Gold at Tartan Lake and Announces Termination of Churchill Group Private Placement

TORONTO, ONTARIO -- (Marketwire - July 12, 2011) - St. Eugene Mining Corporation Limited (TSX VENTURE: SEM) (“St. Eugene“ or the “Company“) announces that it has received initial drill assay results from its Phase 1 drilling program on its wholly-owned Tartan Lake Gold Mine project in Flin Flon, Manitoba. Drill hole TL-11-01 was collared along a surface shear structure and has encountered gold mineralization over good-sized widths. Assay results include intercepts as follows:

Hole       Visible
                   Width (m)    From (m)    To (m)   Au g/t
TL-11-01 	1 	33 	34 	5.86
				
TL-11-01 	2.15 	88.55 	90.7 	3.38
Including 	1.15 	88.55 	89.7 	10.8
				
TL-11-01 	1.34 	92.14 	93.48 	1.94
				
TL-11-01 	2.65 	130.35 	133.00 	2.15
Including 	0.65 	130.35 	131.00 	3.40

Jennifer Boyle, President and CEO of St Eugene Mining commented, “Conducting an exploration program on a Canadian gold project that has sat dormant for decades and that has never had the benefit of modern day exploration tools, is where we are looking to see resource growth. We are very pleased that our initial results confirm the consistency and continuity of the mineralized vein structures. Additional results from Tartan Lake are in process and the Company is considering expanding the drill program.“

Hole TL-11-01 is 450 meters long, collared at 334° azimuth and -55° dip, and is located in the vicinity of the South Zone of the Tartan Lake deposit identified and worked on by the previous operators, Claude Resources Inc. (“Claude“) and Granges Exploration Inc.

At the Tartan Lake Gold Mine Project, approximately 1,495 meters have been drilled to date (7 holes) of a proposed 4,000 meter surface drilling campaign. Assays announced in this news release are preliminary and reflect results received up to date (first two batches which contained 200 core samples). Further assay results from the same hole are pending. The potential grade disclosed herein is conceptual in nature and there has been insufficient exploration to define an updated mineral resource on the Tartan Lake Gold Mine Project. It is uncertain if further exploration will result in the target being delineated as an updated mineral resource.

The Company further announces that it has formally terminated the previously suspended transaction with Churchill Natural Resource Partners, L.P. in light of the unsolicited proposal from Claude referenced in Claude's press release dated July 11, 2011.

The special committee of independent directors continues to consider Claude's proposal and intends to comment further following careful consideration of the terms and Claude's purported value for the proposal to St. Eugene shareholders.

The Company has implemented a rigorous Quality Assurance and Quality Control program to ensure best practices in sampling and analysis of drill core. Drill core was halved and samples averaging 0.5 to 1.5 metres were submitted to TSL Laboratories in Saskatoon, Saskatchewan, ISO approved facilities. Quality assurance and quality control procedures have been implemented including the use of blanks, standards and duplicates. Core samples were analyzed by a 30 gram gold fire assay with an atomic absorption, conventional gravimetric and/or screen fire techniques.
