AYM Anglesey Mining Plc

    Core drilling programme at Parys Mountain

Anglesey Mining plc is pleased to report the long awaited commencement of a
planned drilling programme at its Parys Mountain copper-lead-zinc-silver-gold
property in Anglesey, North Wales. A Boyles drilling rig, contracted from Irish
Drilling Limited, arrived on site on 9 June and the first hole was spudded on 11
June. The diamond drill is operated by drillers all of whom have previous
experience of drilling at Parys Mountain.
The programme is planned to consist of up to 2,000 metres of surface diamond
drilling in four holes to further explore for mineralisation at three different
targets: the Northern Copper, White Rock and Engine zones.
Despite its long history, and the identified resource base of 6.5 million tonnes
at over 10% combined metals, the Parys Mountain deposit is only partially
explored and considerable potential remains to significantly increase the
resources already identified on the property. The proposed drilling is based on
a comprehensive reassessment of the geology of Parys Mountain carried out by the
company over the past eight years.

Northern Copper Zone
Throughout the 1800s there was extensive underground mining over a strike length
of 1.2 kilometres aimed at extracting the siliceous copper ores, lying beneath
and to the north of the old open pit, at the top of the volcanic setting. In the
1960s drilling by various companies explored the down-dip continuation of this
mineralisation to depths 500 metres below surface. A geological resource of 30
million tonnes, with an average grade of about 0.7 per cent copper, was
estimated at that time, based on widely spaced drill holes, some of which
intersected only part of the total thickness of mineralisation.
However, of current note, the drill core in this northern Copper Zone was not
routinely assayed for gold (not unusual in the 1960s when gold was at a value of
US $35 per ounce) and only scant information is available as to the distribution
of gold within the Northern Copper zone. Drill hole AMC14, the last hole drilled
by the company in its previous programme in 1998, intersected 2.49 grams per
tonne of gold, with low base metal values, over 0.65 metres, at the projected
updip periphery of the Northern Copper zone.
One of the objectives of the current drill programme is to follow up on hole
AMC14 and obtain data on the distribution and grade of gold within the Northern
Copper zone. At an estimated 30 million tonnes, the Northern Copper Zone is a
large deposit but with an average copper grade of less than 1% it is unlikely to
be economic. The identification of higher grade areas which might be selectively
mined within the overall Northern Copper area, together with information on gold
distribution, will be valuable.
The first drill hole of the current programme is located on the northern flank
of Parys Mountain and is targeted to intersect the Northern Copper Zone horizon
at a projected depth of about 200 metres and then go on to explore for Engine
zone horizons at greater depths. At 7.30am on Monday 20 June 05 the hole was at
a depth of 148 metres.
The drilling programme at Parys Mountain is expected to continue for about four
months throughout the summer.
