DRILL TARGETS CONFIRMED AT SKY LAKE GOLD PROJECT

Tri Origin Exploration Ltd. (TSX-V: TOE) (?Tri Origin? or the ?Company?) is pleased to announce that induced polarization (?IP?) geophysical surveying has identified very strong anomalies in covered terrain nearby historic gold occurrences at the 70 square kilometre Sky Lake gold property located 35 kilometres southwest of Pickle Lake in north-western Ontario. The IP program covered an area of approximately 2 kilometres by 2 kilometres at the east-central part of the property approximately 3 kilometres west of significant gold occurrences last explored in the 1980?s. The objective of the program was to confirm that sulphide-bearing rocks associated with these gold occurrences extended to the west under overburden cover and, if surveying was successful, to delineate and prioritize targets for a follow-up diamond drilling program.

Results from the IP program have been received and analysed. A total of 23 discreet anomalies ranging from 200 metres to over 800 metres in length were detected. Of these, 7 are very strong responses and another 10 are classified as moderate to strong and 6 of these are coincident with conductive responses detected by an airborne VTEM electromagnetic survey completed by the Company in 2010. These results are very encouraging and significant as review of historic information from the region indicates that gold is associated with sulphide mineralization that has given moderate to strong IP response in earlier surveys. The association with airborne electromagnetic responses may also indicate the presence of buried massive sulphide occurrences which are also noted to be associated with gold deposits elsewhere in the Canadian Shield.

The Sky Lake gold property covers a 23 kilometre long portion of an extensive and well-mineralized belt of volcanic and sedimentary rocks that lies midway between the past-producing gold deposits of the 2 million ounce Pickle Lake Gold District to the northeast and the Golden Patricia gold mine to the west.  Gold occurrences related to sulphide-rich iron formation and altered, pyritic felsic volcanic rock were identified in these rocks during the 1950?s and early-stage evaluation of these occurrences was conducted up to the 1980?s. Early exploration for extensions or repetitions of these occurrences was hampered by extensive overburden cover. It is the belief of Tri Origin?s management that the effective use of modern exploration techniques will be successful in tracking extensions of these gold zones under cover and in detecting and delineating new prospective targets which may represent as yet undiscovered deposits of gold.

Communication with local native communities in the Pickle Lake region continues in order to inform and consult with them regarding Tri Origin?s on-going exploration and drilling programs within this multi-stakeholder jurisdiction. The Company is working with native communities to ensure that any potential impact to other land uses in the area will be identified and kept to a minimum.

Tri Origin is now planning a diamond drilling program to test selected geophysical targets identified by the IP survey. Depending on winter conditions, the property may be accessible for drilling by skidding a drill across a network of trails and frozen lakes. Otherwise, the property is best accessed by airlift in the spring. It is the Company?s intention to commence drilling as soon as possible during the coming year. Shareholders will be notified upon commencement of the drilling program.
