COPPER RESOURCES CORPORATION
GOLD MINERALISATION DISCOVERED AT HINOBA-AN
COPPER PROJECT IN THE PHILIPPINES
LONDON, United Kingdom - 5 September 2006.
Assay results of cores from the recently completed geotechnical drilling
programme at the Hinoba-an Copper Project of Copper Resources Corporation (AIM:
CRC.L) ("CRC", "the Company") confirm gold-bearing mineralisation. These
results indicate the potential for a significant gold system to the northeast
of the main porphyry copper mineralisation at Hinoba-an.
Geotechnical drilling for the copper project at the northeast wall of the
proposed Don Jose ("DJ") open pit, intersected several intrusive dacites
(silica-rich igneous rocks) and associated hydrothermal breccias (rocks broken
by hot fluids). These rocks represent the feeder zone for dacitic and rhyolitic
(more silica-rich) volcanic rocks that represent the last phase of volcanism in
the belt (circa 13 million years). These late-stage volcanic events are often
associated with metal-rich fluids, which represent the last phase of volatile
release from the underlying magmas. It is these fluids that often cause the
brecciation, or else percolate through a pre-existing breccia and deposit
metals, including base metals, gold and silver.
Mark Gordon, CRC's Chief Geologist, interpreted that these units are
sub-vertical, and trend NW-SE, that is, parallel to the trend of the porphyry
copper deposit. The mineralisation is adjacent to the intersection of a
NW-trending structural zone and a SW-trending structural zone. The SW structure
extends to the Bulawan Gold Project, which is located at the intersection of
this and another NW trending zone 5km to the southwest of DJ. The Bulawan
project, which is also hosted in a similar age dacitic complex, produced some
300,000 ounces of gold before being put onto care and maintenance in 2002, due
to low gold prices.
Significant results show gold grades up to 1.9 g/t, and include the following:
Hole CDG-012
* 85m to 107m - 22m @ 0.35 g/t (0.1g/t cutoff), including 6m @ 0.9g/t from
92m (0.5 g/t cutoff, peak value 1.4 g/t)
* 142m to 161m - 19m @ 0.18 g/t (0.1 g/t cutoff), including 4m @ 0.38 g/t
from 147m
Hole CDG-013
* 99m to 101m - 2m @ 0.506 g/t (0.1g/t cutoff)
Hole CDC-014
* 27m to 29m - 2m @ 1.1g/t (0.1g/t cutoff), including 1m @ 1.9 g/t (1.0g/t
cutoff)
* 128m to 132m - 4m @ 0.11 g/t (0.1 g/t cutoff)
The geotechnical drilling programme included 17 holes for 1976.5 metres, of
which seven intersected rocks associated with the dacitic intrusive complex and
three returned significant gold assays.
As the geotechnical drill holes were drilled at a spacing of 200 metres, as
required for the bankable feasibility study (BFS) for the copper project, and
have not covered the full extent of the area considered prospective for gold
mineralization, there is significant potential for the area to host a major
gold system. CRC will embark on a 50x50 metre drilling programme to ascertain
the extent of the mineralization and contained gold. The latter grid will bring
the new gold drilling up to a BFS standard as well. CRC will use the drill rig
still at site to complete this programme.
Chris Jordinson, CEO of CRC, stated, "The substantial gold discovery is
exciting, as it has the potential for increasing the returns and the Hinoba-an
project economics to a very attractive level."
