DRILLING CONFIRMS DEEP EXTENSIONS TO BASE METAL DEPOSITS AT WOODLAWN, NSW

TriAusMin, the registered Canadian trading name of Tri Origin Minerals Ltd. (TOR:TSX, TRO:ASX) is pleased to announce interim results from a preliminary drilling programme being conducted at its Woodlawn Project, 200 kilometers southwest of Sydney, NSW. The Company has intersected base metal-rich mineralization at significant depths below historic underground workings at the past-producing Woodlawn mine. A first deep hole has been completed to a depth of 1236.1 metres and a "wedge" or daughter hole started at 404 metres down the first hole has also been completed to a depth of 955.4 metres as measured from surface. The second hole is currently being completed and a wedge hole will be extended from it to investigate a strong down-hole electromagnetic geophysical anomaly detected during surveying just completed by the Company. Sample results from the first hole and its wedge cut have been received. Significant results are:

The wedge hole (WLTD009A) intersected 2.35 metres (approximate true thickness 2.00 metres) grading 0.9% copper, 1.3% lead and 13.8% zinc at 658.75 metres down-hole as measured from surface. This intersection is believed to represent the edge of the down-plunge extension of the "D" zone approximately 300 metres below the deepest level where it was previously mined.

The "parent" hole (WLTD009) intersected down-plunge extensions to mineralization representing the previously mined "I", "B" and "J" zones. In this hole these zones are represented by strongly altered rock containing metre-thick beds of massive pyrite and wide zones of disseminated pyrite across down-hole intervals of up to 60 metres.

Assaying through these zones revealed elevated base and precious metal values of up to 7 grams per tonne silver, 0.7% copper, 0.4% lead and 0.7% zinc across 1 metre at 535 metres down-hole at what is believed to be the down-plunge extension of the "I" zone and 2.2% zinc at 907 metres down-hole at the southern limit of the down-plunge extension of the "B" zone. At 1068 metres down-hole an 11 metre interval of sulphide-rich rock was intersected which is believed to represent the fringe of the down-plunge extension of the "J" zone. It was also anomalous in metal content with 1 metre samples returning values of up to 0.6% zinc, 0.5% copper and 4 grams per tonne of silver.

While in production, the Woodlawn open pit and underground mine produced approximately 13.4 million tonnes of high-grade ore from a number of separate, fault-bounded massive sulphide zones or lenses mined to a maximum depth of 600 metres below surface. At the commencement of this drilling programme, it was the Company's belief that some of these lenses remained open both at depth and at shallower levels along strike.

Management is very pleased to report that its first deep drill hole, completed with little geological data to be used as a guide, has intersected an ore grade extension to one of the lenses targeted. Very strong sulphide mineralization and alteration was intersected at a second, third and fourth anticipated target. Furthermore, geophysical surveying conducted in the second hole now in progress has returned a strong anomaly nearby the hole in the anticipated location of another targeted lens. This adds well-founded confidence to the Company's geological interpretations and its belief that significant new deposits remain to be discovered at Woodlawn.

These two holes are the commencement of a longer-term drilling programme designed to test for the possible occurrence of extensions to ore lenses or new deposits nearby the past-producing mine. A substantial Mineral Resource previously released by the Company exists in the vicinity of historic underground workings and it is TriAusMin's objective to add to this Resource through continued drilling at Woodlawn.

All samples are of sawn � NQ diameter drill core, sampled to geological intervals or nominal 1metre intervals. Drill core recovery through the sampled zones was generally 95 to100%. Samples were analysed at ALS Chemex Labs in Orange, NSW. Initial assays are by method ME-MS61, (48 elements) which is four acid digestion followed by ICP-MS and ICP-AES analysis. Base metals (Cu, Pb, Zn) greater than 1% and Ag >100 ppm are re-analysed by method ME-OG62, which is a four acid digest with HCL Leach and AAS finish. Gold analysis is by method Au-AA25, which is a 25g fire assay with AAS finish. TriAusMin inserts Certified Standards and Blanks at regular intervals to verify assay and sample preparation procedures.
