FOR IMMEDIATE RELEASE:
April 11, 2007
DRILLING
COMMENCES FOR WOODLAWN FEASIBILITY STUDY, NSW
Tri Origin Exploration Ltd (TOE: TSX-V) is
pleased to announce that its 53.9%-owned subsidiary Tri Origin Minerals Ltd.
(TRO) has commenced drilling as part of its feasibility study at the Woodlawn
Underground project in New South Wales, Australia. An initial
geotechnical hole has been completed and was successful in intersecting mine
openings at the past producing Woodlawn Mine. The deepest of these openings
was at 300 metres below surface and was dry. This is significant as it
will allow TRO to access underground workings without the time and cost
involved in dewatering to that depth. Drilling will continue at the mine
and at other TRO exploration projects within the Lachlan Fold Belt.
The News Release as issued by TRO to the
Australian Stock Exchange (ASX) is as follows:
Last week Tri Origin Minerals Ltd
(TRO) announced the commencement of the Woodlawn Zinc Copper Project
feasibility study. The Company is pleased to announce it has commenced drilling
at Woodlawn as part of this study and drilling activities will be ongoing at
and near Woodlawn and other TRO tenements within the Lachlan Fold Belt of New
South Wales.
As part of the feasibility study a
hole was drilled to ascertain the water level in the existing underground
workings. This hole intersected two separate mine voids and did not
encounter any water. The workings at the base of the hole are approximately 300
metres below surface. This is a significant finding in that gaining access to
underground to at least this depth will not entail mine dewatering. This may
reduce the cost of mine evaluation during the feasibility study and estimates
for mine rehabilitation. The mine was considered a relatively dry operation as
verified by this initial result.
It is planned to also use the drill
rig to conduct mine and infrastructure site geotechnical surveys.
Within the Lachlan Fold Belt the
Company has a significant exploration landholding considered highly prospective
for volcanogenic massive sulphide (VMS) deposits.
Two drill holes are planned within EL
6493, each targeting coincident geophysical and geochemical anomalies within
the prospective Woodlawn Volcanics about 4 kilometres west of the Woodlawn
Mine. Around 600 metres of drilling is planned with follow up down hole
electromagnetic surveys. The Company is exploring for Woodlawn style
mineralisation (zinc rich VMS).
Following the completion of these
holes and prior to further drilling at Woodlawn drilling is planned at the
Overflow Prospect (EL5878) located approximately 180 kilometres west of Dubbo, New South
Wales. Drilling at Overflow will:
·
Further assess the extent of mineralisation
below the old Overflow Mine; and
·
Evaluate down dip potential of highly
anomalous gossans (assaying up to 18% lead) and coincident geophysical
anomalies.
Previously reported drill results
from the Overflow Mine that reflect the target mineralisation potential include
significant intercepts such as:
·
Hole TBB001 (7 metres from 163 metres @
5.93g/t Au, 28g/t Ag, 0.1% Cu, 1.7% Pb, 4.0% Zn); and
·
Hole TBB008 (6 metres from 236 metres
@ 7.61g/t Au, 22g/t Ag, 0.4 % Cu, 1.6 % Pb, 2.2 % Zn).
