PILBARA GOLDFIELDS - VISIBLE GOLD IN FOLLOW-UP SAMPLING
The directors of Thor Mining Plc ("Thor") (AIM, ASX: THR) are
pleased to advise visible gold from sample panning of the second
phase of gold, nickel, and chromium geochemical sampling at the
100% owned Pilbara Goldfield tenements (E46/1262 and E46/1190) in
Western Australia.
HIGHLIGHTS:
-- 17 of the 32 stream sediment samples had visible gold in panning
-- Two of the 2019 sample sites (19PST22 and 19PST32) had
visible gold in multiple follow up stream sediment samples (tables
1 & 2)
-- Samples 20PST04 and 20PST24 returned 13 and 11 grains respectively from panning
-- Gossan with prior nickel in rock chips was mapped and sampled over 800 strike metres.
Mick Billing, Executive Chairman of Thor Mining, commented:
"This appears to be a highly successful follow up, to the
previous, very successful, sampling program."
"To find visible gold in multiple sites in very close proximity
to previous gold samples is very encouraging".
"We look forward eagerly to confirmatory gold assays along with
assays of the potential nickel site samples".
A total of 32 stream sites and 49 gossan sites were sampled
(tables 1 & 3) and are now undergoing laboratory assay with
results expected to be available in two to three weeks.
The program was designed to follow up the eight most encouraging
sites from the 2019 reconnaissance program in addition to locating
and testing the area of gossan identified by the WA Geological
Survey.

Gold Anomalism
Eight stream sediment sample sites from the 2019 sampling
program had follow up sampling. The best gold panning results show
further gold in multiple stream sediment samples upstream of two of
the 2019 test sites 19PST22 and 19PST32. These two sites have
similar geological settings and are situated approximately 800
metres along strike of each other. The areas directly up stream of
each site require follow up evaluation as well as the entire 800
metre strike length between the sites.
Gold assay results are to follow.

Nickel Anomalism
An extensive area of gossan was located within the north south
trending band of ultramafic rocks along the western side of the
tenement. The gossan extends over 800 metres of strike length and
is up to 75 metres wide. A previous WA Geological Survey rock chip
sample assayed 1080 ppm Ni.
Rock chip samples were collected from 49 sites covering as much
of the gossan as outcrop and topography would allow. These samples
have been despatched for laboratory assay.
Observations of the sampled gossan included; colloform textures,
spongy leached jarasitic/limonitic rock, massive ironstone,
silcrete capping and manganese staining. No preserved primary
textures or structures were observed within the gossan.
