Summary
The Solomon Gold exploration effort on Guadalcanal continues to deliver results
which indicate the extensive nature of mineralized intrusive host rocks in the
tenement area. Mineralisation extends in a 4 km wide corridor from the south
coast of Guadalcanal to the Gold Ridge deposit, a distance of some 28 km over
which Solomon Gold holds tenure over 25 km. The results to date while not yet
having defined a definitive resource, confirm the presence of suitable intrusive
host rock bodies at several locations over this distance and at heights ranging
from 600 to 1250m above sea level. Mineralisation ranges from porphyry style
copper molybdenum at the low levels ( Chikora Prospect, 600m asl, currently
being drilled ) and the high level Sutakiki epithermal low temperature veins at
1250m asl.
The exploration program in the Sutakiki and Koloula Valleys to date has
identified east west vein sets which are mineralized at potentially economic
grades, subject to the discovery of sufficiently intense veining. The
exploration programs at Sutakiki, including Valehailala creek and at Mbina, 4 km
to the south, at both locations of which mineralised vein sets have been
identified, are focused on that aim. Post mineralization faulting has disrupted
these vein sets resulting in the unpredictability of drill results to date
The exploration effort at Chikora, 2 km south south west of Mbina is targeting a
copper molybdenum porphyry in an area where vertical drilling by Utah in the
1970s is believed to have underestimated the grade of the mineralized porphyry
system.
Sutakiki and Koloula
Since the Company's previous exploration update in July 2007 it has completed a
further five drillholes and commenced two more in the Sutakiki and Koloula
Valleys for 2,277 metres of drilling. Assay results have been received for SK07
and SK08, and results are awaited for SK09 and SK10. Holes SK07 and SK08 were
drilled on the western side of the SK01 discovery hole and outcrop. Both holes
intersected predominantly Suta volcanics with only minor alteration and
mineralization. These results and the regular identification of mineralization
in east west trending veins support a model for structural control of gold
mineralization at Sutakiki. A similar structural control is evident at Mbina,
4km south of Sutakiki, in the Koloula Valley. Sutakiki and Mbina lie within the
same north north east trending structural zone, which also hosts the 2M ounce
Gold Ridge gold deposit 13 km north east of Sutakiki and the promising Chikora
copper-molybdenum porphyry prospect 2km south south west of Mbina.
At Valehailala Creek, 500 m north of the SK01 discovery hole at Sutakiki, a
landslide has exposed an outcropping zone of east west quartz carbonate and
sulphide veining approximately 50 metres wide containing gold grades up to 3.99
g/t from rock chip samples of the mineralized veins. The Company has commenced
drilling this zone with drillhole SK1, currently at a depth of 80m in
mineralisation
At Mbina channel sampling of outcropping polymetallic veins emplaced in broad
zones of low grade mineralized host porphyry returned grades of up to 1.5m @
9.34 g/t gold, 393 g/t silver, 0.94% copper and 0.74% zinc.
Drillhole KL01 was drilled into this zone of gold and copper mineralization and
encountered anomalism over the entire hole with best results over 1m intervals
of 6.77, 2.36, 1.28, 1.25, 1.26, 3.61, 3.43, and 1.93 g/t gold in thin veins
with associated copper, zinc and lead mineralization.
Assay results have so far only been received to a depth of 454 metres and the
balance of the assay results for this hole to total depth of 554 metres are
awaited. The mineralization at Mbina is diagnostic of a gold and zinc rich halo
on the margins of a significant porphyry copper body. The Solomon Gold
exploration team believes the source porphyry zone to lie to the south west
within 2 km. Chikora is the main target and is currently being drill tested.
(see below)
Drilling of hole KL02 has commenced and is testing the eastern extension of
these vein sets and associated magnetic lows postulated to have developed as a
result of more intense alteration and mineralization. Drillhole KL02 is
currently at a depth of 117 metres and has intersected vein style mineralization
in altered and weakly mineralized host rocks from 60 metres. A further drill
hole KL03 is planned to test vein extensions and an additional target to the
west, exhibiting an intense magnetic high signature, considered diagnostic of a
magnetite rich porphyry core zone.

Chikora - Vurakave.
At Chikora copper and molybdenum mineralization is evident over a 2.5 x 1.5 km
zone in which soil sampling data collected by Utah International in the 1970s
and Solomon Gold's subsidiary ARM in the late 1990s and augmented by recent
sampling, has returned values over 3000 ppm copper. Molybdenum is also present
and has been assayed up to 0.17% in rock chip samples at the Vurakave prospect
on the north east of the Chikora grid. Mapping and rock chip sampling at
Vurakave has identified intermittent zones of quartz veining containing visible
molybdenite over a 600m x 200m zone of interest.
At Chikora, Utah drilled 13 short vertical holes in the 1970s. The best hole was
CH08 returning 115m @ 0.34% Copper and 142 ppm Molybdenum from 152m to 266m and
showing mineralisation strengthening with depth,. Maximum values of 0.76% Cu and
820ppm Molybdenum (0.082%) were intersected in the zone near the end of the
hole. The hole was drilled vertically and is believed to have missed the
sub-vertical quartz copper molybdenum sulphide veins outcropping in the Chikora
prospect area.
Solomon Gold has designed a two hole inclined programme to a depth of 600 metres
to test the true grade of the mineralization evident on north south and east
west vein sets at Chikora. Field work is continuing on the Vurakave area on the
north eastern part of the Chikora grid, where high grade molybdenum samples on
the north south vein set have been outlined.
The Chikora prospect is situated at a vertical elevation of between 650 and 1000
metres above sea level, and only 6 km from the south coast of Guadalcanal. The
Chikora prospect is believed by Solomon Gold geologists to represent a deeper,
copper and molybdenum phase of the gold/ zinc/ lead mineralization evident at
higher elevations at the Mbina (850 to 1100 m asl ) and Sutakiki prospects ( 950
to 1300 m asl).
Nickel exploration
Nickel exploration has commenced on the Nggela prospect in the Florida Islands,
north of Honiara. The area was selected by Solomon Gold as a lateritic nickel
target, after the identification of nickeliferous ultrabasic rocks in the area.
Solomon Gold geologists have identified a 5 km2 area underlain by weathered
ultrabasic rocks with visible nickel oxides and silicate mineralization
characteristic of the saprolite or lower horizon in a nickel laterite prospect.
Upper iron rich levels are also evident in surface scrapes and cuttings on the
outcrops.
The company has commenced a program of pitting to collect bulk samples on a 150
x 150 m grid for analysis.

About Solomon Gold plc
Solomon Gold holds extensive tenements on the main Island of Guadalcanal Solomon
Islands, for minerals exploration, focusing on Copper and gold rich porphyry
systems. The company listed on AIM on 10/2/06 after a £5m capital raising. The
company has identified a very extensive area of mineralisation indicative of
significant porphyry copper gold and epithermal gold mineralization systems and
is currently conducting a three rig program drilling key targets. Solomon Gold
believes the area to host potential for the discovery of a world class copper
gold porphyry system similar to other large orebodies in the region such as Ok
Tedi, Grasberg and Bougainville. The company is staffed by an active team of
expatriate and Solomon Island geologists and field hands, supported by
integrated logistics support services including a helicopter contract.
The program is now augmented by the services of two drilling contractors
operating a total of three rigs for Solomon Gold, and a helicopter service
contract.
It is the current intention of Solomon Gold to define a world class porphyry
copper gold deposit with an overprinted epithermal gold deposit and ultimately
bring it to production. Solomon Gold has access to the required exploration
development and financing skills to achieve this goal. The south western Pacific
Rim of Fire is host to a number of ore bodies which have hosted in excess of 40
million ounces of gold and copper as gold equivalent. These projects exemplify
the potential evident between Sutakiki and Chikora.
