Goldplat plc ('Goldplat' or 'the Company')
Kenyan Lolgorien Licence Area Update
Goldplat Plc, the AIM listed gold producer, is pleased to provide an
update with regards to its ongoing evaluation programme at its 50%
owned joint venture Lolgorien project within the historically
producing Migori Archaean Greenstone Belt in south western Kenya.
Its joint venture partner is Oslo and Swedish-NGM listed
International Gold Exploration AB ("IGE").
Highlights
* Kilimapesa Hill - Rock chip sampling at a 3m spacing in a strike
drive has identified a stretch of 42m at 10.13 g/t gold ("Au")
* Kilimapesa Hill - two parallel auriferous veins, situated
approximately 60m apart can be traced over a strike length of
600m
* Kilimapesa Hill - auriferous quartz veins can be traced along
surface for up to 1.2km as marked by artisanal workings
* Alpha Ray and Red Ray - Induced Polarisation ("IP") surveying has
defined a geophysical anomaly 2 km in length striking east-west
* Alpha Ray and Red Ray - Drill programme planned to test the
quartz veins currently being worked by artisanal miners at
surface level
* Tailings derived from colonial operations have been auger drill
sampled and a JORC compliant mineral resource of 51,648t at
2.52g/t Au defined.
* Planning a refurbishment programme on existing gold processing
plant on site providing short term production potential
Demetri Manolis, CEO of Goldplat said, "These results represent yet
another step towards achieving our strategy of becoming a leading
mid-tier gold mining house. Historical workings and artisanal mining
attracted us to this prospect and the results from the first phase of
our evaluation programme are highly encouraging. Importantly, this
initial evaluation programme aimed at defining a mineral resource
from the surface tailings was completed ahead of schedule and within
budget. As a result, we are delighted to be in a position where we
can plan a refurbishment programme on an existing plant, with the aim
of processing the ore produced from primary and tailings targets in
the near future."
Results
The joint venture initially identified 10 prospective targets in its
Lolgorien project. Its current areas of focus are Kilimapesa Hill,
Alpha Ray and Red Ray, and Maghor:
Kilimapesa Hill - Adits
Five adits have now been groove sampled and four strike drives, which
were previously developed on quartz veins, were channel sampled. The
mapping of two adits in Kilimapesa Hill shows that two parallel
veins, situated approximately 60m apart, can be traced over a strike
length of 600m. Rock chip sampling at a 3m spacing from the
western-most adit, Adit B, has returned a 42m stretch averaging 10.13
g/t over a stoping width of 1.4m. Samples taken from the eastern and
western extremities of the drives confirm that the gold
mineralisation continues to the east and west as well as at depth.
In addition, rock chip samples taken up to 4.5m on either side of
the quartz vein show gold values up to 3.7 g/t Au, demonstrating
that, in this area, gold is not merely restricted to the quartz
veins.
The quartz veins lie within intercalated shales, banded iron
formations and greywacke metasediments. Correlation of the
stratigraphy and quartz veins has been proved by geological mapping
in the adits and of the surface artisanal workings. The surface
expression of the veins, as marked by artisanal workings,
demonstrates a potential strike length of 1.2 km.
Maghor, and Alpha Ray and Red Ray - Geophysics
Two IP programmes were completed at the Maghor target area, and the
Alpha Ray and Red Ray target area. IP at the Maghor area has
identified chargeability and resistivity highs over fault
intersections, which are coincident with the site of artisanal
activity. The IP at the Alpha Ray and Red Ray target areas has
identified a high chargeability and resistivity anomaly 2km in length
striking east-west, which is considered to be the IP response to
quartz veins currently being mined by artisanal miners.
Tailings
Tailings derived from colonial operations in the mid-1900s have been
auger drill sampled and a JORC compliant mineral resource defined by
external consultants. Combined measured, indicated and inferred
mineral resources are 51,648t at 2.52g/t Au. The majority of these
tonnes lie within 200 metres of the existing plant infrastructure.
Initial gravity and carbon-in-leach metallurgical testwork on the
colonial tailings show that recoveries are in excess of 65%, and on
the ore derived from the quartz vein ore bodies in excess of 85%.

Company's net interest in the project is 50%.
Next Steps
At Kilimapesa Hill the next phase is to increase exposure of the
quartz veins. The existing reef drives at Kilimapesa Hill will be
extended to the east and west with a total of five ends being
developed. The joint venture is also planning to develop an adit some
40-50m vertically below the existing adits to access the down dip
extension of the quartz veins.
At Red Ray and Alpha Ray the adits will be developed to intersect the
quartz veins currently being worked by artisanal miners at surface
level. It is anticipated that up to four development ends will be
created. Further drilling along strike will help to evaluate the
quartz veins as indicated by the IP response. All material emanating
from development along quartz veins will be stockpiled for future
processing.
Some of the other IP targets are considered drill-ready and will be
drilled when the large capacity RC drill rig, currently in transit
from Sweden and scheduled for arrival in November 2007, is
operational.
Goldplat and IGE are sufficiently satisfied as to the future
potential of the targets selected to now start planning a
refurbishment programme on the existing plant. A metallurgical team
is currently assessing the work required to get the plant into
working condition. The plant is in a good condition.
Further details
The joint venture, in which the Company has a 50% interest, was
signed in July 2007 with Oslo and Swedish-NGM listed International
Gold Exploration AB ("IGE") and registered in Kenya as Kilimapesa
Gold (Pty) Ltd., has adopted a phased approach for the development of
the highly prospective Lolgorien project. The initial phase involved
an evaluation of the 10 selected targets within the licence area
including sampling within existing adits developed in the 1980s,
undertaking IP programmes, and shallow auger drilling of historic
tailings. This phase was completed on budget ('$109,000') and three
weeks ahead of schedule. Notably, the current work is expected to be
financed from existing cash resources.
The Migori Archaean Greenstone Belt, where the Lolgorien licence area
is located, is a northern continuation of the Lake Victoria
Goldfields, which hosts many major gold deposits including Barrick's
multi-million ounce North Mara mine, which lies approximately 40 km
to the southwest of the Lolgorien property. The licence area has
been the site of considerable historical gold mining and is still the
focus of artisanal mining. Official reports, starting from the early
1900s, show that between 1920 and 1950 the area produced nearly 1
million ounces of gold.

Notes
The underground chip sampling was done using a pneumatic Atlas Copco
rock hammer. The samples were assayed by Set Point Laboratories Ltd
in Johannesburg. Samples were milled in an LM2 mill to a nominal 85%
passing 75µm. A 50g sub-sample of the assay pulp is fused in a lead
collection fire assay with silver as a co-collector. The resulting
prill is dissolved in aqua regia and presented for ICP-OES finish to
quantify the gold content in the sample. Detection limits were set at
0.01 ppm. The joint venture uses blanks and certified standards to
ensure QA-QC. The values received from Set Point displayed high
correlation with the inserted controls.

geological and/or grade continuity but are spaced closely enough for
continuity to be assumed.
INFERRED RESOURCE: that part of a mineral resource for which tonnage,
grade and mineral content can be estimated with a low level of
confidence. It is inferred from geological evidence and assumed but
not verified geological and/ or grade continuity. It is based on
information gathered through appropriate techniques from locations
