Vangold Resources Ltd.: 3D IP Survey Report for Fergusson and 3D IP Survey Update for Mt Penck Papua New Guinea
10 September 2010 - 4:56AM
Marketwired
Vangold Resources Ltd. ("Vangold" or the "Company") (TSX VENTURE:
VAN) is pleased to report it has completed a three dimensional
induced polarisation (3D-IP) geophysical survey conducted at Mt
Penck EL 1322 (area 102 sq km) located on New Britain Island and
the Igwageta Prospect, EL 1324 - Fergusson (area 115 sq km), Milne
Bay Province, Papua New Guinea. The 3D-IP preliminary reports at Mt
Penck define five geophysical targets which are interpreted to
related sulphides including pyrite, chalcopyrite and arsenopyrite.
An association of arsenopyrite with gold occurs in drillholes at
Kavola. The 3D-IP survey at the Igwageta Prospect (Fergusson) EL
1324 defines the presence of excellent new targets for bulldozer
trenching and drilling, shows significant mineralisation depth
potential, and has confirmed the existing gold mineralisation and
structural interpretation.
A seven week exploration program at the Igwageta Prospect, which
commenced in April and was completed in late May 2010, covered an
area of approximately 1.0 km2 (1.2 x 0.8 km). The area of interest
was cut with access/soil sampling lines at nominal 100m spacing. A
three dimensional induced polarisation (3D-IP) chargeability and
resistivity survey was completed over the gridded area.

The 3D-IP survey was designed to test for geophysical responses
related to the Igwageta Prospect and to locate additional,
potentially gold and silver epithermal mineralised trends. The
modelled resistivity results are being used as a diagnostic tool to
interpret silica flooding targets, which management believes may be
related to gold mineralisation. The chargeability defines anomalies
related to sulphide mineralisation, and is potentially associated
with gold veining and gold mineralisation.
A total of nine targets have been identified that are either
associated with gold mineralisation, or are potentially related to
additional gold bearing quartz reefs. The Igwageta gold vein
assemblage (IG1) occurs as an elongated 430m long zone of slightly
anomalous resistivity (300 to 400 ohm.m) trending west-northwest.
The eastern section of this vein assemblage is interpreted to be
faulted to the north and re-occur as an anomaly (IG7).
Within the gold anomalous areas of Igwageta at IG 1, 3, 4, 5
& 6, higher chargeability values occur over an area of 400m by
250m and extend to more than 200 meters in depth. These zones of
higher chargeability potentially reflect gold mineralisation
associated with arsenopyrite sulphides.
The Igwageta vein systems (IG 1, 2 and 3) and associated
'historic' gold in soil geochemistry, correlate with a linear zone
of magnetite alteration (destruction due to hydrothermal fluid
flow, that is, it is a gold mineralising environment) in the
airborne geophysical data. A similar magnetic low lineament to the
Igwageta vein that has not been investigated is located about 600m
to the northeast. These areas occur in a broader (3 1/2 sq. km)
circular zone of alteration, and are evident as anomalously low
airborne magnetic and radioelement signatures.
The Igwageta vein system, the magnetic lineament to the
northeast, and the surrounding zone of magnetite alteration, are
proposed as locations for a future expanded soil sampling and 3DIP
geophysics survey. These surveys are recommended to cover 1.4 km by
1.6 km and may delineate further drill targets by defining
anomalies related to concentrations of gold vein and gold sulphide
related mineralisation. As discussed above, the resistivity
component of the survey is expected to help delineate areas of
silica flooding that may be related to gold mineralisation. Gold in
trench samples also correlate with arsenic, which may be detected
as sulphide related anomalies in the IP component.
For part of the survey, five pits were dug and sampled and
visible gold were observed from weathered C-horizon rock collected
from the base of the pits that was panned. In addition, a zone of
soil and drill hole gold anomalism shows visible gold in the
altered rhyolitic volcanics. Several occurrences were noted by
macroscopic evaluation at the locality, but the occurrences are too
fine grained for standard photography.
Within the next ten days, Vangold expects to receive
comprehensive reports from SJ Geophysics with processed results on
the geophysical surveys conducted on each of the Company's three
gold properties (Mt. Penck, Fergusson and Allemata). Peter
Swiridiuk, a consulting geologist and member of the Australian
Institute of Geoscientists and Australian Society of Exploration
Geophysicists, will be interpreting the results.
Vangold also announces that it has received preliminary results
from it 95% owned prospect on New Britain Island, Mt Penck. The
3D-IP which has recently been completed indicates the presence of
an IP anomaly located in the area of Kavola South. This geophysical
anomaly expands at depth. The Company expects elevations and
sections of the 3D IP work conducted at Mt Penck within a week. At
which time it will issue a comprehensive Press Release.
Vangold's three gold properties (Mt. Penck, Fergusson and
Allemata) are located in Papua New Guinea along the "Pacific Rim of
Fire", the active circum-Pacific volcanic belt that is host to
large copper-gold porphyry systems (Grasberg, Ok Tedi, Panguna and
Frieda River) and to a number of world class epithermal gold
deposits including Porgera and Lihir.
