» Summary
Of the 40,670 ha comprising the Woodjam
North property only 10% has been explored by Fjordland
to date. Takomkane intrusives in Takla volcanics form
a contact halo producing multiple alkalic to sub-alkalic
gold-copper porphyry deposits. Grades of mineralized drill
intersections have a relatively high gold to copper ratio
with trace amounts of molybdenum similar to Northgate
Mineral's Kemess South and Kemess North deposits in northern
British Columbia (Kemess South – Original Resources (1998):
202 Mt @ 0.224% Cu, 0.63g/t Au). The Kemess South Mine
produces approximately 300,000 ounces of gold and 75 million
pounds of copper per year. Further information about the
Kemess gold-copper porphyry deposits is available at www.northgateminerals.com.
Three open-ended zones of porphyry mineralization
have now been drill tested on the Woodjam property; namely
the Megabuck, Deerhorn and Takom Zones. Drilling
in each of the zones continue to support the property's
potential to host large bulk-mineable gold+copper deposits.
» Megabuck
Zone
The Megabuck Zone is located on the
flanks of a large IP chargeability high. A total of 17,236
metres of drilling in 67 holes have been drilled into
the Megabuck Zone from 1974 to the present.
Mineralization in the Megabuck Zone
occurs as a large, irregular and complex tabular-shaped
gold-copper mineralized zone approximately 175 metres
thick trending northeast and dipping approximately 45°
to the southeast. Drilling has extended mineralization
over 300 metres to a depth of over 400 metres.
Mineralization is consistent with a porphyry-type
goId-copper style of mineralization, occurring in a complex
pile of brecciated monzonite intrusives and potassic-sericitic
altered volcanics and subvolcanics. Although gold and
copper content of the volcanics is markedly less than
that of the monzonite, it still contains up to 1.85 g/t
gold. Gold-copper ratios are consistent at approximately
1g/t Au to 0.14% Cu.
The continuity of mineralization from drilling
to date suggests that the system has a strong likelihood
for continued expansion to the south and east and to depth.
Monzonite intrudes highly altered, fractured and brecciated
volcanics, containing numerous irregular monzonite lenses
and fragments.

» Takom
Zone
The Takom Zone, located approximately
2.5 kilometres south of the Megabuck Zone, is defined
by large (~ 500m x 1500m) coincident IP chargeability
and copper geochemistry anomalies. The zone is underlain
by hard dark grey andesitic rocks of the Takla Group volcanics
composed of partly brecciated augite and feldspar porphyry
flows and volcaniclastics containing patchy chlorite and
argillic alteration, cut by quartz-carbonate veins. The
volcanics are intruded by granodiorites, biotite-quartz
diorites and monzodiorites likely related to the Takomkane
Batholith.
The Takom Zone has seen a limited amount
of previous drilling (18 holes totalling 3,366 m) and
mostly to shallow depths. Successive drilling programs
have returned progressively better results; the highest
grade and most northerly hole assaying 127.4 m grading
0.13 g/t Au and 0.26% Cu, including 32.8 m grading 1.04
g/t Au and 0.45% Cu.
There is a high gold-copper corridor transecting
the lower grading Takom Zone copper mineralization,
apparently striking 46° and dipping 61° SE evidenced by
the IP chargeability pattern and 3-point extrapolation
from drill holes.

At this time the potential for copper-gold
mineralization is open laterally and to depth.
» Deerhorn
Zone
The Deerhorn Zone is located 1.5
kilometres northeast of the Megabuck Zone. The
zone is characterized by a chargeability high zone delineated
by the 2007 IP survey and was drill tested in 2008 by
2 holes located 100 metres distant from each other. Gold-copper
mineralization was encountered near the bedrock surface
in both holes and is open in all directions. Deerhorn
represents a very significant discovery because of its
similar character and spatial association to the Megabuck
area.
Overburden thicknesses average ~ 50 metres
and outcrop is non-existent. The geology, as understood
from current drilling, is a magnetite/chlorite altered
quartz monzonite with grey quartz vein stockwork containing
chalcopyrite mineralization.
Drill results from all holes drilled to
date in the Deerhorn Zone follow:
An interval containing 42.3 ppb Au and 0.90%
Cu over 15.4 metres, including a sub-interval of 340 ppb
Au and 7.2% Cu over 1.14 metres, was intersected in hole
03-30. This higher grading interval came from quartz-carbonate
veining and semi-massive chalcopyrite mineralization in
fractured, brecciated and altered volcanics.
