The 2021 precious metals exploration program at Liwa, which included extensive surface sampling and a drilling campaign, has just been completed. Drilling has intersected zones of heavy sulphide mineralization accompanied by promising geological indicators such as silicification and banded veins at 100m downhole (Figure 1). Core samples from this year’s drilling program have been submitted to ALS Australia for assay.

Expansion of Mineralization
Mapping north of the current exploration zone has revealed a previously undiscovered expression of breccias and banded quartz veins seen elsewhere on the property (Fig.2). This indicates that hydrothermal activity was present over a much greater area than previously thought.
This region forms a 1km extension of the prospect and represents a roughly 50% increase of the total area of interest. The company hopes to reinforce these observations with the upcoming results of this seasons’ soil sampling program and will be using this data to plan its 2022 drilling campaign.
Surface sampling has uncovered a previously undiscovered outcrop of breccia with grades of up to 1.01 grams/tonne (g/t) gold (Au) and 22.3g/t silver (Ag) (Table 1). This new outcrop has allowed for structural measurements of the breccia to be taken and will greatly aid in targeting future drill programs.

Soil sampling and portable x-ray fluorescence (pXRF) analysis at the Korokayiu Volcanogenic Massive Sulphide (VMS) prospect has now been completed and has highlighted several base and precious metals anomalies within the surveyed areas (Figure 3 and 4).
All six of the soil sample grids returned anomalous copper and zinc (+/- lead-silver) pXRF anomalies. The Kula 1 grid has proven to be the most promising, as it shows anomalous copper-zinc values over and 500 metres trend that is open off the grid to the east and west.
Soil and rock samples collected during 2021 were analyzed using pXRF, which benefits from being fast, convenient, and low-cost when compared to laboratory analysis. The results of pXRF soil and rock sampling are considered semi-quantitative. To verify the accuracy and precision of this data, select samples have been sent to ALS Australia.
Silver grades have been promising in soil samples, with grades of up to 21 g/t Ag. Copper and zinc grades have also been significant, with the pXRF analysis returning up to 0.41% Cu (Figure 3) and 0.96 % Zn (Figure 4) in soils. Of the six soil sampling grids, Kula 1 has proven to be the most promising, as it shows a good trend of Cu and Zn anomalies open towards the east and west. Additionally, pXRF analysis of crushed rock samples returned grades of up to 6.8% Zn, 0.94% Cu and 24.52 g/t Ag. These results coincide with prospective surface geology and will be targets for future infill sampling and drilling.
The company would like to remind readers that pXRF is a “first pass” analytical method that benefits from being fast, convenient, and low-cost when compared to laboratory analysis. To verify the accuracy and precision of this data, select samples have been sent to ALS Australia.

Following the positive results of the Korokayiu field program, the company will be carrying out a preparatory field campaign on its Nakoro VMS prospect. This will be a short campaign focused on ground-truthing historical data through mapping, grab sampling and structural measurements and analysis (Fig.5). This work will lay the foundation for further work in 2022.

Viti Levu, the main island of Fiji, has a long mining history. It is on the prolific Pacific Ring of Fire, a trend that has produced numerous large deposits, including Porgera, Lihir and Grasberg. The island of Viti Levu hosts Namosi, held by a joint venture between Newcrest and Mitsubishi. Newcrest published Proven and Probable Reserves for Namosi of 1.3 billion tonnes at 0.37% Cu and 0.12 g/t Au (5.2M ounces Au and 4.9M tonnes Cu). Namosi is now undergoing environmental assessment as part of the permitting process. Lion One Metals is now developing its Tuvatu Project, with Indicated Resources of 1.00 million tonnes at 8.48 g/t Au (274,600 ounces Au), and Inferred Resources of 1.33 million tonnes at 9.0 g/t Au (384,000 ounces Au) reported at a 3.0 g/t Au lower cutoff. The Vatukoula Gold Mine has been operating for 80 years, producing in excess of 7 million ounces.

Methodology and QA/QC
The analytical work reported on herein was performed by Australian Laboratory Services Pty. Ltd. (ALS) at Perth, WA. ALS is an ISO-IEC 17025:2017 and ISO 9001:2015 accredited geoanalytical laboratory and is independent of the Thunderstruck Resources and the QP.
Rock samples were subject to crushing with 85% passing 3.15mm and then pulverised to better than 85% passing minus 75 micron. Samples were then split using a riffle splitter. A 0.25 gram sample pulp was then subject to 4-acid (HF-HNO3-HClO4) digestion and analysis through a combination of ICP-AES & ICP-MS (ME-MS61) for most elements, including silver. A 30 gram fire assay fusion (Au-ICP22) was used for gold determination.
Portable X-Ray Fluorecence (pXRF) analysis was performed on dried soil samples through a clear plastic bag. Samples were not sieved or pressed. Regular calibration was performed, with blanks and standards being introduced into the analysis at regular intervals. Approximately 16% of samples will be submitted for confirmation analysis at ALS Australia.
Thunderstruck Resources follows industry standard procedures for the work carried out on the Liwa prospect, with a quality assurance/quality control (QA/QC) program. Blank, duplicate and standard samples were inserted into the sample sequence sent to the laboratory for analysis. Thunderstruck Resources detected no significant QA/QC issues during review of the data. Thunderstruck Resources is not aware of any sampling, recovery, or other factors that could materially affect the accuracy or reliability of the data referred to herein.
