VANCOUVER, June 16 /PRNewswire-FirstCall/ - Copper Ridge
Explorations Inc. (TSX.V:KRX) (the "Company") is pleased to
announce that a 1,500m drill program has commenced at its Duke
Island copper-nickel-platinum-palladium (Cu-Ni-PGE) property in
southeast Alaska. The Company has
the right to earn up to a 65% interest in the Duke Island property
from Quaterra Resources Inc. (NYSE-A: QMM / TSX-V: QTA)
("Quaterra").
The planned drill holes will target high grade massive to
semi-massive Cu-Ni-PGE sulphide mineralization within the Marquis
Zone of this ultramafic intrusive complex. The drill targets have
been defined by interpretations based on geological mapping,
historical drill results and three-dimensional modeling of a
variety of geophysical surveys including magnetics,
electromagnetics, induced polarization, magnetotellurics and
gravity. The historical drilling did not extend to the basal
contacts or the feeder/conduit area of the intrusive complex, where
highest grades of sulphide mineralization are expected to
occur.
Cu-Ni-PGE sulphide mineralization was discovered on Duke Island
by Quaterra in 2001. Between 2001 and 2006, Quaterra completed
geological mapping, soil and rock sampling, ground and airborne
geophysical surveys and 1,820 m of core drilling in 11 holes. The
discovery includes copper, nickel and PGE enriched sulphide
mineralization within an Alaska-type zoned ultramafic intrusion in
Alaska's Alexander Platinum Belt.
The occurrence is unique in the high percentage of disseminated and
net-textured to massive sulfide mineralization within certain
phases of the ultramafic intrusions. Outcrop samples have returned
values from less than 10 ppm Cu to 2.8% Cu, from less than 10 ppm
Ni to 0.25% Ni and from less than 5 ppb to over 1 ppm PGE from the
South Rim of the Marquis prospect. Nine of eleven core holes
drilled at the South Rim of the Marquis prospect intercepted from 6
to 90 m of semi-massive to massive sulfide containing highly
anomalous values for Cu (10 to 12,500 ppm), Ni (27 to 4,694 ppm),
Pt ((less than)5 to 680 ppb), and Pd ((less than)5 to 548 ppb) and
established a north dip to the upper contact of sulfide
mineralization. Modeling of EM and Natural Source Audio-frequency
Magnetotellurics (NSAMT) survey results defines an eastern plunge
and a wine-glass shaped conduit below the covered conductive
anomaly at the Marquis prospect, reminiscent of other high grade
magmatic sulfide deposits. The historical drilling focused on the
western periphery and shallower southern portions of the main
Marquis Zone. The current drill program will focus on the area of
Quaterra's best drill results, in the area of the strongest
geophysical targets, but will extend the tests to greater depth.
