Highlights
• Gold assays at Sutakiki confirm widespread high grade gold in quartz
veins up to 39 g/t gold with spot assays up to 1020 g/t gold, 3.3per cent.
copper and 228 g/t silver. Average grades, in the veins sampled, are 7.34
g/t gold and 0.41 per cent. copper.
• Coherent high grade gold mineralisation in multiple quartz veins at
Sutakiki evident over a 150m wide 1500m long zone. Extensions to 500m wide.
• Additional drilling rig contracted for 5000m drilling program at
Sutakiki
• Drilling at Mbetilonga encounters mineralised and altered porphyry
system at Hahala
• Eight drillholes for 2400m planned at Grovers Hill, and Vatuchichi,
Mbetilonga project
• Access agreement in principle reached at Kuma project
The Directors of Solomon Gold plc ('The Company' or 'Solomon Gold') are pleased
to advise of the latest exploration and operations activities on the Company's
search for world class copper gold orebodies on the Island of Guadalcanal,
Solomon Islands.
Since the last Operations Update, on 8 August 2006, the Company has continued to
advance the exciting Sutakiki gold discovery and has advanced to drilling
activity on the Hahala porphyry project north of Hambusimaloso at Mbetilonga, 14
km south of the national capital and the Company's base in Honiara.
Recently the Company reached agreement in principle with landowners to gain
access to the Kuma Valley to the immediate south of Sutakiki and the east of
Koloula. Subject to documentation this will provide Solomon Gold with access to
a highly prospective mineralised system believed to include the Sutakiki project
and the upper Koloula Valley, covering approximately 50 sq. km within which
there are numerous drilling targets. The Company is negotiating a second
agreement with a new drilling contractor for 5000m of diamond core drilling in
the Sutakiki Valley.
Sutakiki is ready to drill
The Sutakiki gold prospect has now been defined as a zone of high grade gold
mineralisation in quartz veins, emplaced in a mineralised porphyry system. The
project occurs in prospective host rocks over an area of approximately 4 sq. km
in a drainage basin of the upper Sutakiki River, 30 km south east of Honiara.
The veining carrying the rich gold overprint has been defined over an extent of
approximately 1 km long and 150m wide. Recent sampling has also indicated an
extension to mineralisation up to 500m wide.
Solomon Gold mapped and sampled 68 individual and separate veins crossing a
tributary of the Sutakiki River. All samples carried potential ore grades
commonly ranging up to 39.6 (and a maximum of 1020) g/t gold in veins up to 5 cm
thick.
Only areas of outcrop were sampled and numerous fine veins were not specifically
sampled. Recent sampling by Solomon Gold geologists has indicated that the host
porphyry is also mineralised at up to 0.8g/t gold and 0.25 per cent. copper. In
the sampling programs to date, copper grades up to 3.3 per cent. were returned.
The chemical signature of the samples continues to indicate that it is the upper
part of the mineralised system that is exposed.
In the veins sampled in the two recent sampling programs gold grades averaged
7.34 g/t gold and copper grades averaged 0.41 per cent.. Solomon Gold considers
on the characteristics of a typical southwest Pacific copper gold porphyry
system, that both copper and gold grades in both the veins and the host porphyry
should increase with depth.
Owing to the size of the system and the apparent high tenor of mineralisation at
surface, Solomon Gold is moving to drill test the target immediately. Ten drill
holes have been planned to test the mineralised zone to a vertical depth of
approximately 500m. Drilling activity is scheduled to commence in late October.
A plan of the proposed drillhole locations and the accompanying plan of assay
results from mapping and sampling in the Sutakiki River are available on the
Solomon Gold website www.solomongold.com
Mbetilonga - Mineralised porphyry encountered in drilling
At Mbetilonga, the company has completed drilling MB 04 at the Hahala prospect.
The drill hole terminated at a depth of 200m and intersected a variably
fractured and mineralised porphyry from surface. The drillhole was designed to
test an area of relatively high gold in soil samples, coincident with a magnetic
feature thought to indicate a magnetite rich porphyry system, Elsewhere in the
Mbetilonga area, pieces of highly magnetic and copper mineralised volcanic rock
occur in the volcanic agglomerates without yet presenting a copper mineralised
porphyry host. The drilling rig has been turned around on the same drilling pad
and is now drilling MB05 to test the same porphyry to the south, including the
contact zone with the surrounding host volcanic rocks. The contact zone is
thought to be the source of high grade mineralisation, assaying 55 g/t in a
reconnaissance sample from the area previously.)
Assays are awaited for drill holes MB03 and MB04
Following the completion of Hahala hole MB5 the Company will commence drilling a
line of coincident gold and magnetic anomalies to the north at Vatuchichi, where
epithermal gold vein float has been sampled returning 55 g/t gold. Recent
mapping has also identified a further area of visible base metals sulphides in
loose vein material at surface and assays are awaited. Vatuchichi is believed to
be geologically similar to Newcrest Mining's Halmahera (Indonesia) mine, where
high grade epithermal gold mineralisation underlies a limestone cap . The
Vatuchichi and Grovers Hill gold in soil and magnetic anomalies are planned to
be tested with a further eight drill holes for approximately 2400m of drilling
in the next half year. Definition of drill targets at Vuralanggoma on the east
side of the Mbetilonga project is continuing. An extensive zone of
silicification and sulphide mineralisation has been mapped and assay data is
awaited. A plan of the proposed drillhole locations and the accompanying plan of
assay results to date from mapping and sampling in the Mbetilonga area are
available on the Solomon Gold website www.solomongold.com
Kuma access agreement
Solomon Gold has successfully negotiated access in principle to the Kuma Valley.
The agreement is currently being documented. The Kuma valley lies to the south
of the Sutakiki area and has not previously been the subject of any recorded
geological exploration whatsoever. From the air Solomon Gold has recognised an
extensive alteration system covering over 4 sq. km in an eroded drainage basin
and a trail of mineralised boulders visible in the Kuma River which emanate from
the centre of the drainage.
Geophysical and geochemical reconnaissance stream sediment sampling data
suggests that the Kuma Valley mineralisation may be contiguous with the Sutakiki
Valley approximately 10 km to the north north west, now known to be highly
auriferous; and the Mbina and Chikora prospects in the Koloula Valley
approximately 8km to the west north west, also known to be highly auriferous.
Sampling and mapping work conducted previously by Solomon Gold's wholly owned
subsidiary Australian Resource Management in 1997, has led to the identification
of geological, geochemical and geophysical features which define a highly
prospective 50 sq. km priority target area in host rocks diagnostic of an
environment capable of hosting a major world class copper gold orebody.
Aeromagnetics and Electromagnetics to target sulphide bodies
Solomon Gold is currently finalising details for a comprehensive stream sediment
and river float sampling program in the Kuma Valley and other highly prospective
drainages east of the SutakikiValley and an airborne aeromagnetics and
radiometrics program over the Kuma tenement. In addition the airborne survey
will include an electromagnetic survey over the Mbetilonga project area and the
50 sq. km priority target area over the upper Kuma, Koloula and Sutakiki
Valleys. The airborne electromagnetic survey is expected to rapidly define
conductive sulphide targets for drilling.
