THOR MINING PLC
Completion of initial drilling program with positive Copper and
Gold results
Alford East Copper-Gold ISR Project, South Australia
The directors of Thor Mining Plc ("Thor") (AIM, ASX: THR, OTCQB:
THORF) are pleased to advise copper and gold intercepts
significantly above the Mineral Resource Estimate (MRE) cut-off
grade, on completion of the initial diamond drilling program at the
Alford East Copper-Gold Project, SA.
Project highlights:
-- Nine diamond drillholes totalling 878m are now complete; with
assays from first two drillholes received.
-- Significant intercepts including:
21AED001 32.9m @ 0.4% Cu and 0.31g/t Au from 81.5 m, and
5m @ 0.5% Cu and 1.02g/t Au from 102m
21AED002 59.9m @ 0.31% Cu from 21.9m
-- Positive correlation between assay results and preliminary
pXRF readings for 21AED001 and 21AED002, gives Thor greater
confidence in pXRF for future drill targeting (AIM: THR
Announcement 2930 June 21).
-- Significant pXRF copper readings (to be confirmed by
laboratory assays) including:
21AED005 73m @ 0.74% Cu from 6.3m (pXRF)
21AED004 50m @ 0.45% Cu from 6m (pXRF)
-- 21AED002, 21AED006 and 21AED007 were drilled up to 100m to
the north of the MRE domain, with assays extending the known copper
mineralisation along strike
-- Assays from the first two drillholes highlight grade uplift
along the north-south trending controlling structure, validating
the new geological model and structural controls on
mineralisation.
-- A water bore was successfully completed for initial ISR pump
testing and hydrometallurgical test work.
-- Remaining assays expected over the coming weeks.
Nicole Galloway Warland, Managing Director of Thor Mining,
commented:
" The new geological model and drill targeting is paying off.
The uplift in copper and especially gold grade, adjacent to what
appears to be a controlling structure is very exciting and beyond
the Directors expectations, suggesting potential for an extended
zone of higher-grade copper and gold along this structure.
The intersections of copper mineralisation in three drillholes
drilled up to 100m north of the AE-5 MRE, suggests a structural
link to the AE-8 domain to the NE, and potentially significant
upside to the Mineral Resource Estimate.
These initial copper and gold grades, wide intercepts and
increased depth of weathering are all very encouraging for In-Situ
Recovery, the innovative mining technique that has minimal impact
on the surrounding environment in contrast to conventional open cut
mining".

Project Background
The Alford East Copper-Gold Project is located on EL6529, where
Thor is earning up to 80% interest from unlisted Australian
explorer Spencer Metals Pty Ltd, covering portions of EL6255 and
EL6529 (ASX: THR Announcement 23 November 2020).
The Alford East Project covers the northern extension the Alford
Copper Belt, located on the Yorke Peninsula, SA. The Alford Copper
Belt is a semi coherent zone of copper-gold oxide mineralization,
within a structurally controlled, north-south corridor consisting
of deeply kaolinized and oxidized troughs within metamorphic units
on the edge of the Tickera Granite, Gawler Craton, SA.
Utilising historic drillhole information, Thor completed an
inferred Mineral Resource Estimate (MRE) (ASX: THR Announcement 27
January 2021):
-- 125.6Mt @ 0.14% Cu containing 177,000t of contained
copper
-- 71, 500oz of contained gold
www.thormining.com/sites/thormining/media/pdf/asx-announcements/20210127-maiden-copper.gold-estimate-alford-east-sa.pdf
Based on the nature on the oxide mineralisation, the deposit is
considered amenable to In Situ Recovery (ISR) techniques.

Alford East Diamond Drilling Program Update
Nine diamond drillholes totalling 878m are now complete, with
assays received for the first two drillholes - 21AED001 and
21AED002. This initial program for Thor, focussed only on the
northern portion of the Alford East copper-gold deposit around the
AE-5 mineralised domains, with drilling targeting areas open at
depth and along strike.
Drillhole assay results are reported in Table B and C
(Appendices), with significant copper and gold intercepts
including:
-- 21AED001 : 108.2m @ 0.17% Cu and 0.1g/t Au from 6.2m, including
25.3m @ 0.11% Cu from 6.2m
32.9m @ 0.4% Cu and 0.31g/t Au from 81.5 m, and
5m @ 0.5% Cu and 1.02g/t Au from 102m
-- 21AED002 : 59.9m @ 0.31% Cu from 21.9m, including
Note for In Situ Recovery Thor is targeting broad copper-gold
oxide intervals above the MRE cut-off grade of 0.05% copper.

An inhouse Vanta Series C portable X-ray fluorescent (pXRF)
analyser was used in the field to take copper readings every 0.5m
down each of the holes (gold not measured by pXRF). Preliminary
pXRF copper results as reported for 21AED001 and 21AED002 (AIM: THR
Announcement 29 June 2021), are almost identical to the assay
results, with the assays results slightly higher over some
intervals (Table C). This positive correlation gives the Directors
of Thor greater confidence with the pXRF readings for future drill
targeting.
Preliminary significant pXRF copper readings for all drillholes
include:
21AED001 33m @0.4% Cu from 81.5 (previously reported)
21AED002 55.5m @ 0.28% Cu from 28m (previously reported )
21AED003 26m @ 0.1% Cu from 15m
21AED004 50m @ 0.45% Cu from 6m
21AED005 73m @ 0.74% Cu from 6.3m
21AED006 16.5m @ 0.06% Cu from 44.5m
21AED007 29m @ 0.12% Cu from 20.5m
21AED008 5m @ 0.09% Cu from 36.5
21AED009 NSI - No Significant Intersection above 500ppm Copper
Important notice: The pXRF copper readings are indicative only
with samples being submitted to laboratory for analytical analysis
including gold assay. The Directors believe that with adequate
sample preparation the pXRF analyser will yield high-quality
analytical data. However, there can be no guarantee that this
method provides accurate results similar to those from the
laboratory analysis.

For ISR purposes, drilling was limited to the deeply weathered
lithological profile, testing the extent of the oxide zone and the
depth boundary of the Top of Fresh Rock (TOFR). The copper-gold
oxide mineralisation is hosted within deeply kaolinised (clay) and
metasomatic altered units on the contact between the Olympic Domain
Wallaroo Group metasediments and the Hiltaba Suite Tickera Granite,
Gawler Craton. Copper oxide mineralogy is dominated by malachite
and chalcocite.

Drill targeting based on a new geological model has allowed Thor
to vector in on key controlling mineralised structures and more
importantly zones of higher copper and gold grades. Assay results
from both 21AED001 and 21AED002 highlight grade uplift on the
hanging wall side of the north-south trending controlling
structure, validating the new geological model and structural
controls on mineralisation.
Drillholes 21AED001, 21AED003 and 21AED005 (Section A-A'
6,256,360mN), were drilled through the central portion of AE_5
(Figure 4), designed to validate the geological model and test
areas, open at depth. The high-grade copper and gold intercepts in
21AED001, significantly above the MRE cut-off, opens the
mineralisation up at depth, with 21AED005 pXRF copper readings
highlighting the grade uplift along the controlling north-south
structure.

21AED004 (Section B-B' 6,235,440mN) was drilled along strike to
the north 21AED005, with pXRF reading validating geological model
and higher copper grades along controlling structure (Figure 2, 3
and 5).

21AED002, AED006 and 21AED007 (Section C-C' 6,235,600mN) were
all drilled to the north of the AE-5 MRE domain, with assay results
extending the known copper mineralisation along strike towards
AE-8.

Multi-element analysis of the assay results from both 21AED001
and 21AED002, highlights two distinct higher-grade zones of
copper-gold mineralisation within a broader mineralised envelope.
The lower of the two has a distinct IOCG geochemical signature -
elevated Cu, Au, Mo, Co, Se, Bi & REE (Figure 7 & 8 log
plots). This potentially reflects sulphide oxidation of primary
mineralisation; whilst the upper zone reflects supergene weathered
mineralisation. Once all assays are received a detailed geochemical
analyses and modelling of the zones will be completed.

Remaining drill core is currently being prepared for sample
submission to the laboratory, with all assay results anticipated in
approximately 4 weeks.
In conjunction with the diamond drilling program a water bore
was successfully developed for pump testing. This is part of the
initial hydrogeological baseline work forming part of the 'proof of
concept' for ISR, including water characteristics, porosity, and
permeability testing. Subsequently preliminary metallurgical
studies on potential lixiviants for copper and gold recovery will
commence using ground water samples.
