DRILLING
RESULTS AND PROPERTY ACQUISITION AT KEEWATIN COPPER, GOLD AND URANIUM PROJECT, NUNAVUT
Tri
Origin Exploration Ltd. (TOE:TSX-V) reports that final
assay results have been received and new claims acquired as a result of a
diamond drilling program conducted at the Keewatin project located 120
kilometres west of Arviat in the Kivalliq District of Nunavut. The program
consisted of 6 diamond drill holes totaling 563 metres to test airborne and
ground electro-magnetic geophysical targets within 4 widely-spaced areas
outlined by the Company’s previous work.
Hole EL07-02 contained
7 samples representing 6.9 metres of core, between the depths of 21.5 and 167.4
metres down-hole which returned anomalous values in copper ranging up to 341
ppm (0.034%). The same hole returned anomalous values in uranium intersected in
5 samples representing 5.5 metres of core with values ranging up to 134 ppm
(0.35 lbs U3O8 per tonne). Previous work in the area by Tri
Origin had identified a significant new uranium target area defined by grab samples
of boulders, located nearby the drill site of hole EL07-02 which returned
assays of 8,500 parts per million and 3,380 parts per million uranium, which
equate to 22.1 and 8.8 lbs U3O8 per tonne, respectively.
Hole EL07-03 intersected weakly anomalous gold mineralization with a maximum
assay value of 741 ppb across 1 metre. This hole was located near the
interpreted head of a boulder field which returned values of up to 18.7 grams
of gold per tonne from grab samples of the boulders taken during the
Company’s previous work programs.
These results are
considered important by management as drilling has now confirmed that bedrock
on the property is copper, gold and uranium-bearing. This is the first time
that drilling has been conducted at these targets and represents a very
positive base to move ahead with detailed exploration in these areas. Prior to
this work, important occurrences of copper, gold and uranium had been
identified by the Company but only sampled in boulders of an indeterminate
origin not directly tied to the extensive airborne and ground geophysical
targets defined by Tri Origin.
Based on these results,
Tri Origin has acquired, by staking, mineral rights to an additional 4 claims
totaling approximately 10,000 acres. The initial Keewatin
property consisted of 5 separate claim blocks comprising a total area of 24,275
acres in which Tri Origin was earning a majority interest from BHP Billiton
Diamonds Inc. The new claim acquisition brings the total land package to over
34,000 acres.
Management is
encouraged by the extent and style of mineralization detected during its work programs
at Keewatin. Management has also recognized
distinct similarities between Proterozoic-age rocks at Keewatin
and others of the same age world-wide that are important hosts to major
uranium, gold and base metal mining districts. The Company is planning for a
continuation to its field program at Keewatin
this coming spring.
The Keewatin project was conducted under
the supervision of Chris Pegg, Kirkland
Lake, Ontario, a
geological consultant to Tri Origin Exploration Ltd. with more than 30 years
experience in the exploration industry. Swastika
Laboratories in Kirkland Lake,
Ontario provided the analytical
services for base and precious metal analyses. Gold assaying was performed by
fire assay with an atomic absorption measured finish using 30 gram aliquot
charges. The lower detection limit on these fire assays is reported to be 1
part per billion. Uranium and thorium analyses were performed by Assayers
Canada in Vancouver
B.C.
