DRILLING RESULTS CONTINUES TO EXPAND THE RESOURCE SIZE POTENTIAL - RUNRUNO
PROJECT
The Board of Metals Exploration PLC ('the Company') is pleased to announce that
recent drill results have been received for drill holes MXD26 to MXD31 of the
current diamond drilling programme being undertaken at its Runruno Project.
The current diamond drilling programme is continually producing excellent
results and the Company is well on track with reaching its target of defining a
resource containing in excess of 3 million ounces of contained gold and 50
million pounds of contained molybdenum.

Notes:
1. Collar Coordinates are the coordinates of the collar of the drill-holes. The
drill-holes are inclined -70degrees from horizontal (except hole MXD27 which is
inclined at -55degrees from horizontal), and orientated towards a grid azimuth
of 100degrees (easterly). In general, the drill-holes are spaced on a 100 metres
grid pattern.
2. Reporting of the above intercepts was determined by applying an upper and
lower boundary defined by a low grade cut-off of 0.7g/t Au. Some composited
intercepts include single metre, internal intercept grades of less than 0.7g/t
Au. Isolated single metre intercepts are not reported unless considered to be
significant (i.e. >5.0g/t Au). No high grade cut-off has been applied to the
individual gold or molybdenum assays.
Hole MXD26 intersected one of the high-grade miners' tunnels and was therefore
terminated prematurely at 65 metre depth. Drillhole MXD27 was then drilled from
the same position but inclined at a shallower angle to intersect the same area
as the tunnel and to continue onwards to its final depth of 150 metres.
Importantly, it should be noted that these holes were drilled in an area that is
interpreted to be faulted, with the main fault being the Malilibeg Fault, a
moderately west-dipping extensional fault. The fault is interpreted to obliquely
cut across the mineralised zone, therefore it is possible that the mineralised
zone adjacent to the fault will have been offset.
All of the previously reported holes (MXD1-MXD25, RUD001 & RUD004) were drilled
to the west of the Malilibeg Fault. Drill-holes MXD29 and MXD30 were drilled
more or less through this fault zone. As a result, it is thought that the holes
were collared in the western, down-thrown block and consequently did not
intersect the majority of the mineralised zone in that fault block. The holes
continued eastwards through the fault and intersected the eastern block, beneath
the footwall of the mineralised zone. Although the holes intersected some minor
mineralisation, the main zone was not intersected.
Drill-hole MXD31 was the first hole to be collared in the eastern side of the
fault, and is located 400 metres from the nearest hole. It was an exploratory '
wildcat' hole to determine the stratigraphy and potential for mineralisation.
Although the alteration and geology looked promising, the mineralisation was not
significant in terms of assay results.
Drillhole MXD38 has just been completed, and the Company anticipates that the
results for the outstanding drill-holes will be received within 2 weeks time.
RUNRUNO - RECONNAISSANCE MAPPING
The Company has also been carrying out some reconnaissance mapping in the area
to the northeast of the drilling area, and several outcrops of the main
lithologies hosting the mineralisation have been observed. This is considered to
be very encouraging, providing excellent potential for the discovery of
additional mineralisation to the north and east of the current drilling
programme.
RUNRUNO - METALLURGY
The Company has just engaged the services of a consultant metallurgist to
commence a metallurgical testwork programme with the aim of determining the
various recovery parameters for gold, silver and molybdenum, for a variety of
processing and metal extraction options, such as gravity, cyanide leach and
flotation. This programme is expected to be completed and results received in
about 8 weeks time

RUNRUNO - SAMPLING & ANALYSIS
Sample Preparation
The drill core is taken from the drill site to a secure compound at the
Company's field camp and is logged by the geologist. The drill core is then
split into two equal halves along its long axis, with one half being sampled at
predetermined intervals, bagged and sent for analysis. The remaining half-core
is retained in core boxes and stored on site for future reference.
The bagged half-core samples are being submitted to an independent 'ISO17025
accredited' laboratory for sample preparation and analyses for gold and
molybdenum. All of the half-core samples are crushed by the laboratory and a
900-1000 gram split is taken, pulverized and presented for analysis.
The remaining crushed sample is retained in bags and stored at the laboratory
for a period of three months before being returned to the Company for storage.
These remaining crushed samples will be used in the future for additional
analyses for gold, molybdenum, silver, sulphur and other elements as deemed
necessary, for example, for resource estimation work.
Analytical Techniques
Gold: Gold analysis is by classical 'Screen Fire Assay' technique that involves
sieving a 900-1000 gram sample to 200 mesh (75 microns). The entire oversize and
duplicate undersize fractions are fire assayed and the weighted average gold
grade calculated. This is one of the most appropriate methods for determining
gold content if there is a 'coarse gold' component to the mineralisation.
Molybdenum: The sample is dissolved in Aqua Regia (3:1 HCl:HNO3) and Molybdenum
analysis is carried out by Inductively Coupled Plasma - Optical Emission
Spectrometry (ICP-OES) method.
