Field Work Extends Liwa Creek Gold Prospect; Samples 55 g/t Gold and 379 g/t Silver in Outcrop And Discovers Significant New Gold Zone
In particular, sampling programs have returned high-grade gold and silver assays over previously discovered zones and expanded those zones. In addition, a potentially significant new zone, featuring the highest-grade soil sample yet collected, has been discovered.
Brien Lundin, Thunderstruck’s Chairman stated, “Following up on the successful results from our Rama prospect, field work continues to expand our Liwa prospect as well. In combination with our Nakoro and Wainaleka VMS discoveries, it’s becoming obvious that our Fiji properties offer tremendous potential. We are excited about continuing to advance on all fronts.”
As detailed in the Appendix, prospecting and geochemical sampling programs at Liwa Creek have resulted in the discovery of multiple gold showings over a three-km, northeast-trending structural corridor that is open in all directions.
Two distinct styles of gold mineralization have been identified at Liwa Creek: narrow northeast-trending high-grade gold plus base metal veins lacking significant wall rock alteration typified by the Jensen’s Showing; and dominantly north-south trending wide zones of gold-silver mineralized quartz-sericite-illite-pyrite altered volcanic rocks such as those occurring at the Liwa Ridge Showing and possibly the newly discovered Lower Vatuvatulevu gold target.
The two styles of mineralization exhibit characteristics of sub-epithermal gold-base metal and intermediate sulphidation epithermal gold-silver veins, respectively. The classification is significant in that both deposit styles are interpreted to have close copper porphyry deposit association, with intermediate sulphidation veins being interpreted as shallow-level counterparts of deeper gold plus base metal sub-epithermal veins located alongside porphyry copper deposits.
Juxtaposition of relatively shallow high-level intermediate sulphidation gold-silver vein system and deeper sub-epithermal high grade gold veins is interpreted to indicate overprinting of early deep copper porphyry related high grade gold veins by relatively late high-level gold-silver mineralization. The Company believes this indicates the presence of a significant and long-lived hydrothermal system at Liwa Creek.
Lawrence Roulston, Thunderstruck Director, noted, “The methodical exploration program at Liwa continues to be very effective at outlining this extensive gold system under soil cover. On-going work continues to push out the limits in prospective areas. Liwa already has a footprint in line with major gold-bearing systems. The size and the gold tenor of this system are extremely encouraging, especially in this Pacific Ring of Fire setting that hosts multiple world-class gold deposits.”
Thunderstruck is advancing toward securing joint venture partners on its VMS and porphyry targets as it focuses on this highly prospective gold zone.
About Fiji
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 1.1 million tonnes at 8.17 g/t Au (294,000 ounces Au), and Inferred Resources of 1.3 million tonnes at 10.6 g/t Au (445,000 ounces Au). The Vatukoula Gold Mine has been operating for 80 years, producing in excess of 7 million ounces.

APPENDIX – LIWA CREEK GOLD PROJECT EXPLORATION DETAILS
Rock Sampling
At Liwa Creek exploration was designed to follow-up and expand on broad trenched gold zones at the Liwa Ridge Showing (0.61 g/t gold over 71.3 metres; including 1.2 g/t gold over 26.5. metres); further develop the high-grade Jensen’s Showing (previous outcrop quartz vein rock grab samples returning 36 and 32 g/t gold from outcrop); and locate the source of widespread gold in float rock located within confined drainages of the Lower Vatuvatulevu Creek and Gun showing areas (see the Company’s February 13, 2018 news release).
Of the 55 current rock grab samples collected at Liwa, a total of 15 samples returned greater than 1 g/t gold or 10 g/t silver; and up to 55.2 g/t gold and 379 g/t silver (Table 1).
At the Jensen’s Showing two parallel, northeast trending, high-grade gold bearing quartz veins are exposed in the bed of Wainamoli Creek over a distance of 50 metres. The veins dip 60 to 80 degrees to the northwest and occur along the upper and lower contacts of an approximately 10 metre thick intrusive dyke cutting volcaniclastic rocks of the Wainimala Group.
Rock grab and small diameter backpack core drilling of the northern vein resulted in four (4) samples returning gold assays of 55.2 , 40.2 , 31.9, and 25.5 g/t gold (the later cored over a 0.22-metre true-width of the vein) with associated lead, copper and zinc values. Jensen’s Showing quartz veins are brecciated and contain massive to semi-massive galena, chalcopyrite and sphalerite with vuggy comb to crustiform banded quartz vein textures in association with sericite-illite host rock alteration. The Jensen’s south vein ranges in width from 0.1 to 0.5 metres in width and exhibits similar polyphase brecciated, anastomosing pinch-and-swell, comb and crustiform banded textures, with a total of 6 rock outcrop samples returning between 1.45 to 7.13 g/t gold.

A distance of 100 metres to the east of the main Jensen’s discovery outcrops a rock grab sample of silicified and comb textured quartz veined Wainimala Group volcanic breccia rocks returned 4.62 g/t gold.
Rock outcrop and subcrop float grab sampling within Liwa Creek at the northern extent of the Liwa Ridge Showing, 800 metres west of Jensen’s, returned 4.53 g/t gold and 379 g/t silver (the highest silver assay to date at Liwa Creek), respectively, from silica-flooded and quartz stockwork veined intrusive.
Soils
A total of 141 additional ridge-and-spur aguer soil geochemical samples were collected Liwa Creek. Sampling was designed to isolate potential source zones to the northeast of the Jenson’s gold zone, and widespread gold in float rock recovered within the Lower Vatuvatulevu Creek and Gun showing areas.
Auger soil sampling within the Lower Vatuvatulevu Creek area resulted in the discovery of a significant new gold zone. Prior stream BLEG and prospecting float rock grab sampling within this small 400 x 400 metre drainage returned anomalous gold values. Current soil sampling along the southern ridge resulted in 8 soils collected over a 160-metre interval returning greater than 20 ppb gold, and up to 2,480 ppb gold (2.48 g/t gold) in soil. The result is four times greater than any previous soil sample collected on the project (643 ppb gold from the Liwa Ridge Gold Zone 1.5 km to the west). The five highest soils samples returned 707, 804, 894, 1050 and 2,480 ppb gold. The orientation of this newly discovered gold zone is presently not known. An aggressive follow-up via intensive prospecting, hand trenching and expansion of ridge-and-spur aguer soils to the south is warranted.
In addition, soil sampling along the Gun Showing ridge returned isolated anomalous gold values including 336 ppb and 82 ppb gold, which warrant additional follow-up sampling and prospecting.
Trenching
Hand excavated trenching at three locations (GT1, GT2, and GT3) totaling 29 metres within the Gun Showing area was designed to follow up on previously reported anomalous gold in soil values of 65 and 82 ppb gold (see the Company’s February 13, 2018 news release). Trenches were excavated to a depth of 1 metre into the subsoil, however competent outcrop was not reached in any of the trenches. Trench GT3 returned 0.2 g/t gold over 2 metres from 0 to 2 metres; and 0.17 g/t gold over 3 metres between 8 and 11 metres. Trench GT2 returned 0.12 g/t gold over 2 metres; in addition to silicified and veined float rock grab samples recovered during excavation that returned 0.44, 0.20, and 0.15 g/t gold; including 4.5, 6.2 and 9.6 g/t silver, respectively. Trench GT1 did not return significant values.
Stream BLEG Sampling
Completion of stream BLEG geochemical sampling in the Noda Creek drainage designed to evaluate the potential southern extension of the north-south trending Liwa Ridge Gold Zone. Of the 23 Noda Creek stream BLEG samples collected a total of 13 samples returned greater than 20 parts-per-billion (ppb) gold and are considered anomalous. A stream BLEG collected from the Noda Creek headwaters at the southernmost known extent of the Liwa Ridge gold zone returned 93 ppb gold. This sample represents the highest gold in stream sediment value returned form the Project to date, and underscores the potential to expand the Liwa Zone southward.

Significant High-Grade Lithium Achieved Following Completion of Drill Hole 2 at Rio Grande Sur
HIGHLIGHTS
- Drillhole 2 (DDH-2) at the Sal Rio 02 tenement of the Rio Grande Sur Project, has been completed with substantial high grade intercepts of lithium brine discovered at depths as low as 484m.
- High-grade assays include the following intervals:
- 527mg/L (“milligrams per liter of Lithium”) from an interval of 263m to 265m
- 520mg/L from an interval of 63m to 65m
- 511mg/L from an interval of 159m to 161m
- 506mg/L from an interval of 121m to 123m
- Importantly, some of these grades over 500mg/L were discovered at depth and are beneath the currently calculated mineral resource estimate and are expected to add to its size and grade.
- With completion of DDH-2 the drilling crew has demobilised from site. Demobilisation and suspension of drilling activities whilst interpretting the results from the first two holes has significantly reduced expenditure levels.
- The Stage 1 Drilling Program is targeting resource growth to the existing inferred JORC resource of 251.3kt LCE @ 351mg/L1.
- Following completion of DDH-2, Company’s focus is now on production of Lithium Carbonate from 250tpa Pilot Plant in Salta.
In relation to the completion of DDH-2 at the RGS Project, Pursuit Managing Director & CEO, Aaron Revelle, said:
“The results from DDH-2 continue to be significant as we demonstrate the world class potential of the Rio Grande Sur Lithium Project. With completion of DDH-2, we are seeing consistent increases in Lithium grades to depths both through and below the current mineral resource estimate with the results confirming the potential large scale of the project which the Company anticipates will support a significant low cost, high-grade long-term Lithium carbonate operation. With outstanding high grade brine intercepts of ~500mg/L at depths of ~60m and those grades continuing to ~380m, the project is continuing to exceed our expectations.
“We continue to progress with permitting at our highly prospective Mito tenement in the north of the Rio Grande Salar which will be the location of DDH-3, with the planned location of the hole less than 2km from a neighbouring companies drill hole which achieved 900mg/l Li intercepts being some of the highest grades achieved in Argentina. The decision to drill DDH-3 will be made in 2025, following completion of the permitting process as well as the interpretation of the first 2 drill holes into the resource model which is expected to yield a significant scale where future exploration expenditure may only be warranted in more favourable market conditions.
“In the immediate term we continue works at our Lithium Carbonate Pilot Plant which remains on track to produce our first Lithium Carbonate in the coming months, with Pursuit advancing off-take discussions with multiple requests for product samples from potential off-take partners.”
High-Grade, Deep Depth Lithium Brine Assay Results
Drillhole 2 (DDH-2) of the Stage 1 drilling program was completed on site at the Rio Grande Sur Project in October 2024 having reached a depth of 500m.
Throughout the progress of Drillhole 2, the on-site geologists and drilling team were extremely encouraged by the geological units encountered across the depths of the hole. Of particular interest were 2 sections, the first between 122 and 186 meters, where a sequence of porous sandstone, occasionally interbedded with anhydrite returned lithium grades up to 511 mg/L. A second significant interval was encountered between 240-300m formed by sandstone alternating with gravel, associated with grades up to 527 gm/L of lithium. Both sections returned highly positive results for RBRC (Relative Brine Release Capacity) and Specific Yield, important factors when taking into account locations of pumping well locations for production.
Table 1 – Lithium Assays, Interval Data and Drillhole Collar
Intercepts from DDH-2 have shown highly favourable geology in line with, and exceeding expectations from historical drilling (to depths of 50m) carried out on the Rio Grande Salar. Lithium brine sample grades from the sampling of the hole are averaging above 500mg/L Li against the average grade of 351mg/L Li used to develop the current Mineral Resource Estimate (“MRE”). Additionally, the mineralisation extended to a depth of ~480m also well below the depth used to develop the MRE1.

Industrial Forward Osmosis Update
CleanTech Lithium PLC (AIM:CTL, Frankfurt:T2N, OTCQX:CTLHF), an exploration and development company advancing sustainable lithium projects in Chile, is pleased to update that the industrial forward osmosis ("iFO") unit has arrived and is being installed at the facilities of Condutive Energy in Chicago, USA, where concentrated eluate from the Company´s pilot plant will be converted into battery-grade lithium carbonate. This marks the final piece of equipment required for the downstream conversion process to begin.
Figures 1 to 3: iFO demonstration unit with capacity to process 35 m3/day of eluate arriving at Conductive Energy's site in Chicago, USA
Using iFO has several benefits to the downstream conversion processs, as communicated previously (RNS 19th Sept 2024), such as higher water recovery and lower energy consumption and CO2 emissions compared to using conventional thermal evaporators. This further enhances the potential environmental benefits and process efficiency that the Company aims to achieve in applying Direct Lithium Extraction ("DLE") to produce lithium from brine.
The initial volume of 88m3 of concentrated eluate from Laguna Verde, equal to approximately one tonne of lithium carbonate equivalent ("LCE"), is at Conductive Energy´s facility, with the conversion process to battery-grade lithium to begin in the coming days. With this product, the Company plans to engage with strategic partners for product qualification.
