George Sanders, President of Goldcliff Resource Corporation (TSX
VENTURE: GCN) is pleased to report that highly anomalous silver
values in stream samples highlight the exploration targets on the
Ainsworth Project. These stream samples of 26.61 and 30.01 grams
silver per tonne, in conjunction with additional geochemical and
geophysical anomalies associated with the targets, have confirmed
that three of the established five target areas are of high
exploration priority for silver.
The 26.61 grams silver per tonne result is related to Target 2
(No.1), and corresponds to the No.1 mine geological system. The
No.1 mine, the largest producer in the Ainsworth silver camp, had
historical production of 1.99 million ounces of silver at a grade
of 49.64 ounces per ton. The 30.01 grams silver per tonne result
was discovered by Goldcliff on Target 5 (Bjerkness), which is
eleven kilometres to the north of Target 2.
The five silver targets on the Goldcliff Project claims are
north of the historical Ainsworth silver camp, between Ainsworth
Hot Springs and Kaslo, British Columbia. The five target areas
occur over a distance of 13 kilometres in a north-south direction.
The exploration program on Goldcliff's claims has consisted of
prospecting, geological mapping, stream sediment and soil sampling,
and a 910 kilometre combined electromagnetic, magnetic and
radiometric "Resolve" airborne geophysical survey carried out by
Fugro Airborne Surveys Corp. Follow-up prospecting, geochemical
sampling and trenching are underway.
Acquired by staking in early 2006, the Ainsworth Project claim
position is owned 100 per cent by Goldcliff. The Ainsworth Project
area occurs in the Kootenay Arc -- highly prospective geologic
terrain for silver deposits. The historic silver production for the
Kootenay Arc was from three camps -- Ainsworth, Slocan-Sandon and
Slocan City -- and total silver was 92,500,000 ounces. The Coeur
d'Alene camp, a similar silver camp in the Kootenay Arc, located in
the State of Idaho, USA, had historical silver production of 1.2
billion ounces.
Geological Setting
The Ainsworth silver camp is located in the central part of the
Kootenay Arc, a curving belt of complexly deformed Paleozoic
sedimentary and volcanic rocks (older rocks). The older rocks have
been intruded by Mesozoic and Cenozoic intrusive rocks and range in
age from Lower Cambrian to Upper Triassic. The older rock
lithologies include mica schists, limestones and marbles, homblende
schists, quartzites and slates of the Lardeau, Milford, and Kaslo
Formations, and the Slocan Group. Throughout the region, the rocks
are metamorphosed and strongly foliated in a north-south direction,
dip to the west and are split by strike faults essentially parallel
to the foliation. The older rocks are intruded by Jurassic Nelson
and Cretaceous-Tertiary plutonic rocks. In the Ainsworth silver
camp, the silver deposits occur in the sedimentary, volcanic and
plutonic rocks. The silver deposits have mineralization occurring
as disseminations, replacements and veins.
The silver ore mineralization is associated with sulphides of
pyrite, galena, sphalerite, chalcopyrite, pyrrhotite and
arsenopyrite. Wire silver (native silver) is the only silver
mineral recognized in the camp. The gange minerals are quartz,
calcite, siderite and fluorite. The wallrock alteration is
chlorite, sericite, carbonates, and manganese-bearing minerals.
Located in the Milford Formation (limestone), the No.1 mine --
the largest silver producer in the Ainsworth silver camp -- has had
an historical production of 1.99 million ounces of silver at a
grade of 49.64 ounces per ton. The other significant silver
producers were the Kootenay-Florence, Highland and Highlander
mines, where the silver mineralization was related to the Milford
and Kaslo (volcanic) Formations. In the Slocan-Sandon and Slocan
City camps, the silver is related to the Slocan Group of limestones
and slates.
Airborne Geophysical Survey
The airborne geophysical survey produced encouraging results
that provided important new exploration targets and offer
significant potential for the discovery of additional silver
occurrences within Goldcliff's claims. Due to glacial cover, some
of these geophysical targets, which were in regions of known silver
mineralization, were found in areas devoid of any previous
exploration.
Five high priority target areas were identified that showed a
combination of interpreted potassic alteration, magnetic
association, favourable structural relationships and strong
electromagnetic response. In order to establish priorities and
locations for diamond drill testing, these targets were the first
to be recommended for follow-up ground geochemical and geophysical
exploration. Geophysical anomalies of lower priority, although
still important, are recommended for later ground follow-up.
Ainsworth Project Property Targets
The five silver target areas on the Goldcliff Project claims
occur over a distance of 13 kilometres in a north-south direction
from Ainsworth Hot Springs to Kaslo. Target 2 is to the south and
Target 5 is to the north.
Target area 1 (Big "C") is located in Milford and Kaslo
Formation rocks that are covered with glacial overburden. The "Big
C" geophysical anomaly is a moderate-strength, airborne EM
conductive feature within a group of similar anomalies existing
below glacial cover. Reconnaissance ground VLF EM survey confirmed
the location and the presence of the Big C and of other conductors
near and parallel to a mapped NNW fault. A reconnaissance soil
survey has confirmed anomalous silver, cadmium, lead and zinc
values associated with the geophysics. Target 1 is being permitted
for detailed geophysical and geochemical surveys, trenching and
drilling.
Target area 2 (No.1) is located in Milford Formation rocks and
contains the 26.61 grams silver value in a stream sediment sample.
Target area 2 contains conductors that correlate with a geological
contact near a fault interpreted from a north-south magnetic low
lineament. The most northerly EM conductive trend correlates with a
localized area of interpreted potassic alteration. The moderate to
strong EM geophysical anomalies in this area are about 1 1/2 to 2
km northwest of the "No.1" silver mine and constitute important
targets for ground follow-up exploration.
Target area 3 (Fletcher) is located in Milford and Kaslo
Formation rocks. The Fletcher Target 3 area contains four moderate
strength linear EM conductors that parallel or correlate with
northerly trending mapped faults. Two of these conductive trends
are coincidental with linear magnetic highs and one is associated
with interpreted potassic alteration. Two other conductors are
contiguous with, or close to, geologic contacts. Ground follow-up
exploration is required.
Target area 4 (Woodbury) is located in Milford and Kaslo
Formation rocks. Geophysical anomalies in the Woodbury Target 4
area are similar to those in the Fletcher area just to the north. A
large number of conductive features indicate a complex conductive
environment. Most conductors in Target 4 area correspond with
localized potassic alteration. Ground follow-up exploration is
required.
Target area 5 (Bjerkness) is located in the Slocan Group rocks
and contains the 30.01 grams silver value in a stream sediment
sample. The Bjerkness Target 5 area contains the strongest
conductive features. Conductive trends are predominantly northerly
trending, except for one multiple conductive zone that groups
around a linear conductor associated with a north-south fault.
Mapped and interpreted faults suggest a multiple structural
intersection at the south end of the north-south fault related
conductor. Significant interpreted localized potassic alteration is
associated with most EM anomalies in this area. A reconnaissance
soil survey has confirmed anomalous silver, cadmium, lead and zinc
values associated with the geophysics. Target 5 requires detailed
ground follow-up exploration.
