ROCK SAMPLE RESULTS AT WEST GUQING AREA INDICATE FOURTH PORPHYRY
COPPER CENTRE AT GANGJIANG LICENCE AREA
LONDON - 20 May 2009 - Central China Goldfields plc (AIM: GGG) and
its partner the Sichuan Bureau of Metallurgy and Geological Exploration are
pleased to report sampling results at the West Guqing prospect on the
Gangjiang exploration licence area, Nimu Copper-Molybdenum Project ("Nimu").
Highlights:
- Channel rock sampling results at West Guqing prospect confirm
continuous shallow porphyry copper-molybdenum mineralisation including
supergene copper oxide zones present in the area. Three of the sampling
sites returned continuous significant copper and molybdenum
mineralisation. These are:
- 12 metres @ 0.23% copper equivalent (0.22% Cu and 0.001% Mo)
at site GJT22
- 58 metres @ 0.35% copper equivalent (0.26% Cu and 0.010% Mo)
at site GJT29
- 80 metres @ 0.22% copper equivalent (0.14% Cu and 0.009% Mo)
at site GJT30
- West Guqing is now the fourth copper-molybdenum prospect at the
Gangjiang exploration licence area and reinforces the possibility that
mineralisation occurs as a continuous envelope around the 1.5 x 1
kilometre rhyodacite stock centred at Nading.
Jeff Malaihollo, Managing Director of Central China Goldfields plc,
comments:
"Following the discoveries at the Guqing, East Nading and Gelong
porphyry centres, we have now identified a fourth mineralised centre called
West Guqing.
Drilling in 2008 clearly demonstrated that the East Nading and
Gelong centres are continuous and we have now identifed further mineralisation
in trenches between East Nading and Guqing, between Guqing and West Guqing and
to the west of Gelong.
With this new and significant discovery, the presence of
mineralisation has now been identified along at least 2.5 kilometres and
strengthens the likelihood that the total 5 kilometres corridor surrounding
the central rhyodacite stock in Nading may be mineralised."
ACCESS ROAD CUT SAMPLING RESULTS:
West Guqing prospect is located approximately 500 metres to the
west of the Guqing prospect. It was first recognised in 2007 when trench GJT11
was dug and returned 32 metres of 0.38% copper equivalent (0.16% Cu & 0.025%
Mo). In 2008, a drill road access was constructed and exposed further
copper-molybdenum ("Cu-Mo") mineralisation.
Four sites along the access road at the West Guqing prospect area
exposed mineralised outcrops and sub-outcrops of quartz monzonitic rocks with
Cu and Cu-Mn stains. The road cuts were mapped and continuous 2 metres long
rock chip samples were taken for analysis. The significant assay results of 3
of the 4 sampling sites are outlined in the table below. Results of analysis
for fourth site, GJT28, are still pending.

Note: % Cu Equivalent (%Cu Eq) = %Cu + 9 x % Mo assuming recovery
for both Cu and Mo is 100%
These sampling results confirmed continuous shallow porphyry Cu-Mo
mineralisation at West Guqing prospect including supergene Cu oxide zones.
West Guqing is the fourth prospect recognised in the Gangjiang exploration
licence area and reinforces the possibility that Cu-Mo mineralisation occurs
as a continuous envelope around the 1.5 x 1 kilometre rhyodacite stock centred
at Nading.
SAMPLING & ANALYTICAL DETAILS:
Continuous channel rock samples were taken over two metre intervals
on exposed outcrops and sub-outcrops using a chisel and hammer with a canvas
sheet to catch all the broken rocks. Each sample weighed between 2 to 3
kilograms. A duplicate sample was taken, as close as possible to the original
sample site, after every 20th sample.
The samples were processed and analysed by SGS-CSTC Standards
Technical Services Co., Ltd in China. Sample preparation is done by the
SGS-Xian branch office whilst chemical analysis is done by the SGS-CSTC office
in Tianjin. Pulp samples were digested in aqua regia and analysed for thirty
five elements by inductively coupled plasma-optical emission spectroscopy
(ICP-OES). Routine international-standard QA/QC procedures were used by
SGS-CSTC. Three elements are reported here: copper (Cu), molybdenum (Mo) and
silver (Ag). The detection limit for Cu is 3 parts per million (ppm), while
for Mo and Ag, it is 1 ppm.
