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.
