Thor Mining : 20/09/2017 Pilot Mountain Drilling Completion

Company Announcements Office, ASX Securities Limited, 20, Bridge Street, Sydney, N.S.W. 2000 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 (Figure 1).

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 drillcoreis 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 (Figure 2).

  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.

  Other 2017 holes noted are from the reverse circulation drill program earlier in 2017.

  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%WO3, 0.25%Cu,0.47%Zn).

  • Assay results are awaited to confirm preliminary XRF results of 27m @ 1.1% Cu, 1.3% Zn and0.19%WO3fromsurface including 10m @ 0.32% WO3from17.5m 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.
