Parys Mountain Scoping Study Update

Anglesey Mining plc (“Anglesey” or the “Company”) reports that work on
Scoping Study on the Parys Mountain copper-lead-zinc project in North Wales is
continuing.  The study is being undertaken by Micon International Limited and
Fairport Engineering, in collaboration with company personnel, based on the
resource estimate calculated by Micon in 2012.

The 2012 JORC Code compliant resource estimate reported a resource of 2.1
million tonnes at 6.9% combined base metals in the indicated category and 4.1
million tonnes at 5.0% combined base metals in the inferred category.

The initial approach adopted for the Scoping Study was a plan to mine these
resources at 500 tonnes per day, or 165,000 tonnes per annum, commencing with
development of the mineral deposits closest to surface.  The Company had
chosen this throughput rate as it was believed that the low capital cost
associated with this approach would provide the most beneficial outcome. 
Given the level of indicated resources defined by Micon in 2012, this would
result in a mine life of around 16 years, with mining of the indicated
resources only and none of the inferred resources.

The Company has reviewed the initial outcome of the study, based on a daily
processing plant input of 500 tonnes per day of ore, and concluded that an
accelerated development of the indicated resources over a shorter initial mine
life should be economically more attractive.

Fairport has considered some processing alternatives, specifically the
introduction of dense media separation, that would increase the effective
daily production rate by about 40% with only a limited increase in capital. 
This would result in a shortened mine life based on the existing indicated
resources and should generate an enhanced financial outcome.

In addition, on reviewing the current indicative levels of the capital cost of
mill equipment, including readily available used processing plant, it was felt
that construction of a larger processing plant with a higher throughput rate
could be justified. The feasibility study completed in 1991 was based on a
throughput rate of 1,000 tonnes per day, or 350,000 tonnes per year.

Obviously, a higher initial daily throughput rate would require additional
mine development, a higher capital cost and result in a shortened mine life
based only on the existing 2.1 million tonnes of indicated resources, but it
should generate an enhanced financial outcome.

However, recognising the significant inferred resources of 4.1 million tonnes,
being almost twice the current indicated resources, it would be expected that
during the operation of the mine definition and exploration drilling would be
carried out from underground locations that should be expected to bring much
of the current inferred resources into the indicated category, and that would
then extend the mine life significantly.

Based on an initial review of the preliminary results of the draft Scoping
Study, Anglesey has asked both Micon and Fairport to consider alternative
production and throughput scenarios, at various levels between 500 and 1,000
tonnes per day, and expects to receive modified mine production schedules and
alternative capital cost estimates in the near future.  The inputs will then
be incorporated into updated financial models, with a view to having optimized
development scenarios available for consideration before the end of June 2017.
