UPDATE ON TRI ORIGIN DRILLING AT RED LAKE, ONTARIO.

AUSTRALIAN AFFILIATE FILES ANNUAL REPORT AND QUARTERLY UPDATE.

Tri Origin Exploration Ltd. (the ?Company? or ?Tri Origin?) (TOE: TSX-V) is pleased to announce it has recently completed its first phase diamond drilling program at its Red Lake Extension project (?RLX?) at Red Lake, Ontario. The Company is now planning a winter drilling program at RLX to explore additional targets identified through recent geochemical and geophysical work. This second phase of drilling is planned to commence once ground conditions are favourable for access to drill sites in the area. Core samples from the recently completed program are at the lab awaiting assay. Results will be made public once all assays have been provided to the Company.

RLX is a gold exploration project comprised of approximately 30,000 acres located adjacent to Goldcorp?s mine property and 15 kilometres southeast of Goldcorp?s Red Lake mine. The highly prolific Red Lake District hosts several other major, past-producing gold mines and has produced over 20 million ounces of gold. The Company?s work continues to validate its hypothesis that RLX is underlain by the important mine trend rock units that host the nearby Red Lake gold mines.

Dr. Robert Valliant, president of the Company said, ?We are eager to continue our work in the Red Lake District. Our large land position of approximately 30,000 acres has been ignored previously and is virtually unexplored. We continue to believe the area has the potential to host significant, and as yet undiscovered, mineral deposits.?

The Company is also pleased to announce that its Australian affiliate, Tri Origin Minerals Ltd. (?TRO?), has filed its Annual Report and the report for its most recent quarter ended September 30, 2008. During the quarter TRO completed the feasibility study for the Woodlawn Retreatment Project (?WRP?) and commenced post feasibility project refinement and optimization. As well, TRO completed the final tranche of an equity issue commenced in the previous quarter. TRO?s cash balance at September 30, 2008 was $3.2 million AUD. TRO is continuing to seek off-take agreements and financing arrangements for concentrates from WRP.

The Company will post TRO?s Annual Report and quarterly report on its website at www.triorigin.com. Alternatively, interested parties may view TRO?s Annual Report and quarterly report on the Australian Securities Exchange website at www.asx.com.au (use TRO as the search criteria once on this website).
