THOR MINING PLC
COMPLETION OF DRILLING AT PILOT MOUNTAIN - NEVADA USA
The Board of Thor Mining Plc ("Thor" or the "Company") (AIM,
ASX: THR), is pleased to report completion of drilling at the Pilot
Mountain tungsten project in Nevada, USA.
Highlights:
-- Mineralisation identified extending a further 60 metres down dip at Desert Scheelite
-- Potential second lode identified 20 metres to the north of the existing Desert Scheelite lode.
-- 28 metre wide zone of copper, zinc and tungsten
mineralisation intersected near surface at the Good Hope
prospect.
Detailed logging of the drill core is now complete and samples
submitted for laboratory assay.
Mr Mick Billing, Executive Chairman of Thor:
"Very encouraging initial results from Desert Scheelite and Good
Hope, and hopefully the assays, expected in several weeks, will
confirm this.
"Desert Scheelite in particular continues to shape as very
exciting amongst the suite of deposits at Pilot Mountain, and the
depth extension and potential additional lode to the north
identified in this program represents extremely promising growth
potential."
"The rising Tungsten commodity price recently has increased
interest in tungsten explorers and developers. We have spent
several years building a quality tungsten portfolio and with Pilot
Mountain in the US and Molyhil in Australia, the Company is
uniquely positioned to benefit from a resurgent tungsten
sector."
Desert Scheelite
Drill hole 17DSDD-02 intersected two mineralised zones; the
first representing a potential second new lode approximately 20
metres to the hangingwall (north) of the existing Desert Scheelite
lode. The second intersection down hole represents a 60 metre down
dip extension to the existing Desert Scheelite lode.

Two diamond drill holes were planned at the Desert Scheelite
prospect however only one was completed after 17DSDD01 was
abandoned due to drilling difficulties. Alternative drill collar
locations are in the process of being permitted for subsequent
drilling.
Good Hope
Four reverse circulation (RC) holes and one diamond drill core
hole were completed at the Good Hope prospect. Robust
mineralisation was identified by drilling following up the historic
drill hole result from RGH-02 (36.5m @ 0.4%WO(3) , 0.25%Cu,
0.47%Zn).
-- Assay results are awaited to confirm preliminary XRF results
of 27m @ 1.1% Cu, 1.3% Zn and 0.19%WO(3) from surface including 10m
@ 0.32% WO(3) from 17.5m down hole (reported on 18 August
2017).
-- The Good Hope drilling has delineated a 28-metre-wide zone of
copper zinc and tungsten mineralisation beneath shallow alluvial
cover.
-- Drill hole 17GH-RC02, 70 metres west of 17GHRC-01 (Figure 5) failed to intersect significant mineralisation possibly due to unidentified fault displacement.
A strong mineralising system has been demonstrated at Good Hope
and there remains good potential of further drilling success.

Competent Person's Report
The information in this report that relates to exploration
results is based on information compiled by Richard Bradey, who
holds a BSc in applied geology and an MSc in natural resource
management and who is a Member of The Australasian Institute of
Mining and Metallurgy. Mr Bradey is an employee of Thor Mining PLC.
He has sufficient experience which is relevant to the style of
mineralisation and type of deposit under consideration and to the
activity which he is undertaking to qualify as a Competent Person
as defined in the 2012 Edition of the 'Australasian Code for
Reporting of Exploration Results, Mineral Resources and Ore
Reserves'. Richard Bradey consents to the inclusion in the report
of the matters based on his information in the form and context in
