51 METRES OF MINERALISATION INTERSECTED

 PILOT MOUNTAIN - NEVADA

The Board of Thor Mining Plc ("Thor" or the "Company") (AIM, ASX: THR), is pleased to advise the intersection of 51 metres of mineralisation from the second drill hole designed to test for extensions to the Desert Scheelite deposit at the Company's wholly owned Pilot Mountain tungsten project in Nevada, USA.

Highlights:

·     51 metres of scheelite mineralisation, including 9 metres of visible sulphide mineralisation, including visible chalcopyrite, intersected 25 metres to the east and approximately 50 metres closer to surface from high grade Desert Scheelite intersection from DSDD015;

·     Drill hole designed to follow up the 2012 high grade intersection at DSDD015 (17.5m @ 5.7% Cu equivalent) which comprised; 13.9 metres (m) @ 0.89% tungsten trioxide (WO₃) from 198m, and 17.5m @1.80% copper and 2.2% zinc from 196m (Figure 2);

·     Drill hole sample assays expected within several weeks;

·     Following this very encouraging result, a previously unplanned third hold hole has commenced targeting a further 25 metre extension of the Desert Scheelite deposit;

·     The first hole at Desert Scheelite terminated without intersecting any visible mineralisation, due to what appears to be a fault displacement above the targeted zone of mineralisation.

Mr Mick Billing, Executive Chairman of Thor:  "The objective of testing for potential extension of high grade mineralisation at the eastern end of the Desert Scheelite resource appears to have achieved that aim.  While we await assays to have an indication of the grade of mineralisation, and estimation of the true thickness, extension of the zone with an apparent thickening, is an exciting development for the project."

"While the initial planning for this program at Desert Scheelite included plans for only two holes, we are sufficiently encouraged by this result to immediately conduct a third drill hole to test for further extensions".

The Desert Scheelite deposit currently comprises 100% of the Pilot Mountain Resource estimate of 6.7Mt.  The objective of the two holes programmed at this deposit is to test for extensions to the high grade mineralisation intersected in the last hole drilled into this deposit in 2012.

The two initially planned drill holes targeting Desert Scheelite mineralisation in the vicinity of previously drilled DSDD15 have now been completed.

The first of these (Hole 1) was designed to test for mineralisation 100 metres vertically above DSDD15. This hole failed to intersect mineralisation due to what appears to be fault displacement.

Hole 2 targeted mineralisation 75 metres above and 25 metres to the east of DSDD15 and intersected 51 metres of visible scheelite mineralisation from 142 metres down hole including 9 metres of higher sulphide style mineralisation, including visible chalcopyrite from 172 metres down hole. While this very encouraging drill intersection appears to be comparable with the intersection of DSDD15, assay results are required to confirm actual metal content.

Intersections quoted in this hole, and also for previous drilling results for DSDD15, are down hole measurements only, as at this stage there is insufficient data to adequately assess true width of mineralisation.

A third hole has now commenced targeting mineralisation a further 25 metres to the east of this second hole, following which drilling will commence on the Garnet prospect.
