THOR MINING PLC
DRILLING SUCCESS AT PILOT MOUNTAIN TUNGSTEN PROJECT - NEVADA
USA
Further to the announcement of 19 September 2017, the Board of
Thor Mining Plc ("Thor" or the "Company") (AIM, ASX: THR), is
pleased to advise that it has received positive laboratory assays
from the recent drilling program at the Company's wholly owned
Pilot Mountain tungsten project in Nevada, USA.
Highlights:
Desert Scheelite
-- A second lode 20 metres to the north of the existing Desert Scheelite lode is confirmed.
-- A down dip extension to mineralisation of 60 metres is also confirmed.
Good Hope
-- The 28 metre-wide zone of copper, zinc and tungsten
mineralisation intersected near surface confirmed from laboratory
assays,
-- Drill intersections 70 metres to the west of previous
drilling at Good Hope have added significantly to the known strike
length of this deposit.
Mr Mick Billing, Executive Chairman of Thor:
"I am very pleased to announce, what are for the Thor Mining
board and operational team, exciting drill assay results from both
Desert Scheelite and Good Hope.
"We have long suspected, from geophysical studies, that
additional mineralised lodes exist at Desert Scheelite, and it is
very rewarding to have this validated. This is a very strong target
for drill testing along the entire strike length of the existing
resource with potential, if successful, to add substantially to the
resource inventory'
"Additionally, the high grade and near surface mineralisation at
Good Hope transforms this into a deposit with genuine
potential"
"During recent meetings at the International Tungsten Industry
Association conference in Moscow we have received positive feedback
from a number of parties commenting on the results of our
exploration work, and quality of the asset, at the Company's Pilot
Mountain project."
Desert Scheelite
Significant Assays(1):
-- 17DSDD02: 23.3m @ 0.21% WO(3) from 198m and 15.2m @0.25% WO(3) from 253.3m
(1)Refer to Table 1 for complete intercept summary.
Drill hole 17DSDD-02 intersected two mineralised zones; the
upper intersection represents a new second lode previously
identified by geophysical targeting prior to drilling. The new
second lode sits approximately 20 metres to the hanging wall
(north) of the existing Desert Scheelite lode and may extend the
entire strike length of the Desert Scheelite resource.
The lower 17DSDD-02 intersection represents a 60 metre down dip
extension to the existing Desert Scheelite lode. This down dip
extension may occur along the entire length of the resource.
Good Hope
Significant Assays(1):
-- 17GHRC01: 26.6m @ 0.21% WO(3) , 1.2% Zn, 1.0% Cu from 0.8 metres downhole
-- 17GHRC02: 12.2m @0.12% WO3 from 57.8m and 3m @0.37% WO(3) within 8.4m @ 0.59% Cu from 80.8m.
(1)Refer to Table 1 for complete intercept summary.
A 28-metre-wide zone of copper zinc and tungsten mineralisation
has been confirmed beneath shallow alluvial cover at the Good Hope
prospect.
Better than expected assay results for drill hole 17GHRC-02 mean
a potential 70 metre strike extension of the Good Hope lode to the
west at 423,870mE.
