FOR IMMEDIATE RELEASE:
TRI ORIGIN?S AUSTRALIAN AFFILIATE COMMENCES AIRBORNE GEOPHYSICAL SURVEY OF LEWIS PONDS, NSW
Tri Origin Exploration Ltd. (TOE: TSX.V) is pleased to announce that its Australian affiliate, Tri Origin Minerals Ltd. doing business in Canada under the registered name TriAusMin, has engaged the services of Geotech Airborne Pty Ltd (?Geotech?) to undertake a helicopter-borne geophysical survey of approximately 1,170 line-kilometres over its Lewis Ponds exploration licence located near the town of Orange, 200 kilometres west of Sydney, New South Wales.
Geotech?s Versatile Time-Domain Electromagnetic (VTEM) geophysical system will be used to perform the airborne electromagnetic and magnetic survey which is intended to investigate further the mineral potential within the Lewis Ponds tenement area. The survey is expected to take approximately two weeks to complete after which data compilation and analysis will be carried out.
The Lewis Ponds tenement covers part of an extensive Silurian volcanic and sedimentary belt hosting the major volcanic-hosted massive sulphide deposits of the Lachlan Fold Belt, one of the major mineral producing provinces of southeast Australia. These same rocks host TriAusMin?s Woodlawn base and precious metal deposit 200 kilometres to the south where drilling is currently in progress.
Prior exploration of the Lewis Ponds tenement for gold and base metal deposits by TriAusMin has included both resource delineation drilling and regional exploration activities. Through this earlier work, TriAusMin has discovered, delineated and reported a JORC compliant, Indicated Mineral Resource1 of 6.35 Mt grading 2.4% zinc, 0.2% copper, 1.4% lead, 1.5 grams per tonne of gold and 68 grams per tonne of silver. Numerous other gold and base metal occurrences have been identified on the property. Furthermore, a recently completed exploration data review has generated several high priority target areas and the current airborne survey will assist in prioritizing these areas and lead to the identification of new, prospective targets which will subsequently be investigated by diamond drilling.
The Lewis Ponds tenement is located within a re-emerging gold district which hosts the Cadia and Ridgeway mines operated by Newcrest Inc. and the McPhillamys gold deposit that is owned by Alkane Resources Ltd and is being explored in joint venture with Newmont Australia Limited. Management has long-recognized the favourable exploration environment in the Lewis Ponds region and this programme enhances TriAusMin?s renewed commitment to increase its resource base through exploration.
