Cikoleang Indonesian Gold Project Update
London 27 April 2010 - Central China Goldfields plc (AIM: GGG) is pleased to
announce an update on the Cikoleang Gold Project in the Banten Province,
Indonesia.
As announced on 15 December 2009, the Company entered into an exclusive option
agreement over the Cikoleang Gold Property with a local partner company PT Fino
Bersaudara ("Fino") with a view to entering a definitive joint venture
agreement (the "Joint Venture") within six months. A further announcement was
made on 27 January 2010 following the commencement of field work and the
Company is now pleased to provide an update on the findings so far.
Highlights:
* Thirteen gold vein prospects have now been identified on the Cikoleang
Project area.
* The most promising targets are the Cimapag, CLK and Cimubui vein zones in
the western part and Cikecapi and Cicurug in the southeastern part of the
Cikoleang Project. These areas will now form the focus of our exploration
efforts.
* At Cimapag and CLK, 100-150 metres long NNW-trending vein zones have been
identified and these remain open to the south. Ten rock samples tested from
ore extracted by local artisanal miners returned 0.86 to 22.2 grammes per
tonne ("g/t") gold and 5.5 to 232 g/t silver.
* At the Cimubui prospect, which may be continuous with the CLK vein, two
rock samples taken from a quartz veinlet zone returned 1.19 to 1.48 g/t
gold and 2.7 to 16.8 g/t silver.
* To the southeast of the Cikoleang Project, at Cikecapi, a NNW-trending vein
zone potentially 300 metres long is exposed at surface. A single sample of
artisanal miners' ore returned 18.1 g/t gold and 1140 g/t silver. A further
four rock samples of vein outcrops returned between <1.0 and 26.6 g/t gold
and <1.0 and 96.3 g/t silver.
* Also in the southeast at Cicurug, three vein zones trending NW to NNE are
exposed at surface. Six samples of artisanal miners' ore returned between
less than 1 and 11.9 g/t gold and 9.9 and 256 g/t silver while one outcrop
sample returned 0.58 g/t gold and 80.4 g/t silver.
PROSPECTS & ROCK SAMPLING RESULTS:
Thirteen vein prospects have been geologically mapped and sampled within the
7,891 hectares exploration licence (KP) area. The mineralisation is of an
intermediate sulphidation epithermal vein type where gold and silver are
accompanied by variable amounts of base metal sulphides.
Two dominant structural trends have been recognised: NNW to NW at the eastern
and western portions and ENE to NE at the central portion. From west to east,
the prospects are Cimapag, CLK (previously known as Cikoleang), Cimubui,
Cinyukcruk, Cimancak, Pasir Munding, Sibokor, Lamping Timur, Ciuluran, Cikeper,
Cicurug, Cikecapi and Ciurug Beber. The veins widths are up to 1.5m wide with
strike lengths of up to 300m long.
The most promising of the gold prospects are the Cimapag, CLK and Cimubui vein
zones in the western part and Cikecapi and Cicurug in the southeastern part of
the property. Results of grab samples are shown below:

At Cimapag and CLK, artisanal mining has exposed 100-150 metres long
NNW-trending vein zones which may extend under the rice fields to the south.
Individual veins are <1 to 1.5m thick. Ten rock samples taken from ore
extracted by the artisanal miners returned <1.0 to 22.2 g/t gold (Au) and 5.5
to 232 g/t silver (Ag). Fourteen rock samples taken from vein float and
outcrops returned <1 to 4.1 g/t Au and <1 to 15.1 g/t Ag. The Cimubui prospect
located approximately 500 metres to the southeast of the CLK vein is possibly
an extension of the CLK vein. Two rock samples of a quartz veinlet zone
returned 1.19 to 1.48 g/t Au and 2.7 to 16.8 g/t Ag.
Cikecapi is a NNW-trending vein zone, up to 300 metres long, that is exposed by
artisanal mining. Maximum vein thickness observed is one metre. One sample of
the artisanal miners' ore returned 18.1 g/t Au, 1140 g/t Ag and 3.5% manganese
(Mn). Four rock samples of vein outcrops returned <1.0 to 26.6 g/t Au and <1.0
to 96.3 g/t Ag. At Cicurug, west of Cikecapi, three vein zones trending NW to
NNE are exposed at surface. Six samples of artisanal miners' ore returned <1.0
to 11.9 g/t Au and 9.9 to 256 g/t Ag while one outcrop sample returned 0.58 g/t
Au and 80.4 g/t Ag.
There are eight other vein prospects in the KP area. From west to east, they
are listed below:

ORIENTATION SOIL SURVEY
During March 2010, an orientation soil survey was undertaken at the CLK and
Cikecapi-Cicurug prospects. For each area, two picket lines 100 metres apart
were laid out across known mineralised veins. Soil samples were collected every
25 metres along each picket line including field duplicates every ten samples.
A total of 158 original soil and 15 duplicate samples were collected.
Two sampling and analytical techniques were applied to the soil survey to
determine the most effective sampling method at the Cikoleang Project. The
first technique used total digest analytical methods, i.e. Au by fire assay
with atomic absorption spectrometry (AAS) finish and Ag, Cu, Pb, Zn, Mo,
arsenic (As) and antimony (Sb) by inductively coupled plasma-optical emission
spectroscopy (ICP-OES). The second technique used a partial digest method using
the patented Mobile Metal Ion (MMI) technology of the SGS Group. Based on the
effectiveness of these methods in pinpointing known vein gold mineralisation,
the Company will use the most appropriate technique in future routine soil
surveys across the prospects.
Analytical results from both labs have been received recently. Data
interpretation is still in progress.
ROCK SAMPLING & ANALYTICAL DETAILS
Rock samples, each weighing 0.5 to 1.5 kilograms, were processed and analysed
by PT. Intertek Utama Indonesia, a subsidiary of Intertek. The entire samples
were dried, crushed and fine pulverized to minus 75 microns. Gold was analysed
by 50 grammes fire assay with atomic absorption spectrometry (AAS) finish. For
the other 35 elements including Ag, the pulp samples were digested in aqua
regia and analysed by inductively coupled plasma-optical emission spectroscopy
(ICP-OES). Routine international-standard QA/QC procedures were used by
Intertek. Four elements are reported here: Au, Ag, Zn and Mn. The detection
limit for the various elements are - 0.01 parts per million (ppm) for Au, 0.1
ppm for Ag, and 1 ppm for Zn and Mn.
NEXT STEPS
The initial results are encouraging, but the Company is continuing to conduct
its detailed geological, legal and financial due diligence during its exclusive
six month Option Period over the Cikoleang Project. This Option Period runs to
14 June 2010 and a further update will be provided in due course.
Should GGG decided to form a Joint Venture, GGG will pay additional US$ 10,000
upon signing. GGG's total exposure during the first six months Option Period is
US$ 75,000.
Subject to due diligence Joint Venture terms are as follows:
* GGG will own 75% and Fino will own 25% of the Joint Venture company over
the Cikoleang Project.
* GGG will fund the first US$ 2 million of expenditure.
* Beyond US$ 2 million expenditure both parties will contribute pro rata with
the JV proportions.
* In the event of Fino deciding it does not wish to contribute its interest
will be diluted in proportion down to 12.5%.
* Fino's interest is then held constant at 12.5% unless GGG buys their JV
share based on a mutually agreed price.
