THOR MINING PLC
PILBARA GOLDFIELDS - FOLLOW UP GOLD SAMPLING AT RAGGED RANGE
The directors of Thor Mining Plc ("Thor") (AIM, ASX: THR) are pleased to advise the completion of the third phase of gold geochemistry reconnaissance at the 100% owned Pilbara Goldfield tenements (E46/1262 and E46/1190) in Western Australia.
The program was designed to follow up previously reported success from stream sediment samples collected across the tenements, which defined a highly anomalous 13km long gold target zone, with gold values up to 256ppb (19PST 19F -AR25) and 130ppb (20PST 24F-BLEG); (https://www.thormining.com/sites/thormining/media/pdf/asx-announcements/20200902-asx-rr-gold-sample-results.pdf).
Highlights:
The geochemical program focused on follow up stream sediment gold results, with sampling upstream toward potential source rock, with some additional reconnaissance sampling and one traverse sampled (sediment and rock chip) across the stratigraphy in the anomalous areas (Figure 1).Sampling conducted primarily within the 13 km gold corridor (target zone) trending NW-SE along the mafic/ultramafic thrust faulted contact (Figure 1).The geochemical samples are currently in transit to the Perth laboratory, with assay results anticipated mid-November.The close spaced airborne geophysical survey (airborne magnetics) flown over the full tenure as previously announced is now completed with data processing and modelling underway.

Mick Billing, Executive Chairman of Thor Mining, commented:
"We will continue to aggressively work towards drill target selection at Ragged Range, and this sampling program, along with the airborne magnetic survey just completed, is aimed at achieving that objective."
"We look forward to providing progress updates on Ragged Range, and other projects in the Thor portfolio, as information becomes available."
Gold Anomalism
Approximately five anomalous sample zones (based on 2019 and 2020 sampling programs) were designated for follow up, with sampling upstream toward potential source rocks. These zones reported either or both of elevated assay gold geochemical anomalism, or gold in the pan. In addition, further reconnaissance sampling was conducted in prospective areas where there were gaps in the data.
Sampling focussed predominately along the 13km long gold target zone trending along the thrust faulted mafic/ultramafic contact.
The program also included one rock chip traverse within the anomalous gold zones, designed to sample across the stratigraphy.
Program detail
The program comprised stream sediment trap site sampling with a 3kg -5mm+2mm fraction (coarse) and a 4kg -2mm fraction (fine) sample collected for geochemical analysis for Au 2kg BLEG (fine fraction), aqua regia (fine and coarse fractions) and multi-element analysis.
As well, a further 10-12 kg sample of -2mm material was collected from the trap site for panning in the field. The benefit of this is that eventually we will have four results for gold, (three from the laboratory plus physical gold in the pan) as well as multi-element results.

About Thor Mining PLC
Thor Mining PLC (AIM, ASX: THR) is a resources company quoted on the AIM Market of the London Stock Exchange and on ASX in Australia.
Thor holds 100% of the advanced Molyhil tungsten project in the Northern Territory of Australia, for which an updated feasibility study in August 2018¹ suggested attractive returns.
Adjacent Molyhil, at Bonya, Thor holds a 40% interest in deposits of tungsten, copper, and vanadium, including an Inferred resource for the Bonya copper deposit².
Thor is also acquiring up to a 30% interest in Australian copper development company EnviroCopper Limited, which in turn holds rights to earn up to a 75% interest in the mineral rights and claims over the resource on the portion of the historic Kapunda copper mine in South Australia recoverable by way of in situ recovery⁴. Thor also holds rights to earn a 75% interest in portion of the Moonta Copper project also in South Australia, and is also considered amenable to recovery by way of in situ recovery⁵.
Thor holds 100% of the Pilot Mountain tungsten project in Nevada USA which has a JORC 2012 Indicated and Inferred Resources Estimate³ on 2 of the 4 known deposits. The US Department of the Interior has confirmed that tungsten, the primary resource mineral at Pilot Mountain, has been included in the final list of Critical Minerals 2018.
At the 100% owned Ragged Range Project in the Pilbara region of Western Australia, Thor has exciting early stage results for which gold and nickel drilling is planned.
Thor holds mineral claims in the US states of Colorado and Utah with historical high grade uranium and vanadium drilling and production results.
