Green Technology Metals Limited (ASX: GT1) (GT1 or the Company) is pleased to advise that drilling has commenced at its Root Project, located approximately 200 km west-north-west of GT1’s flagship Seymour Project. Drilling is initially focussed on the McCombe LCT pegmatite.
HIGHLIGHTS
- Phase 1 diamond drilling has commenced at the McCombe LCT pegmatites (Root Project).
- Initial 22-hole, 2,500m program set to confirm McCombe historical drilling and sampling results.
- Phase 2 diamond drilling to target significant expansion of the known McCombe mineralisation.
- Historical drilling demonstrated down-dip continuity at McCombe (including 67m @ 1.75% Li20).
- Total 24,000m diamond drilling program initially planned over McCombe and Morrison pegmatites.
- Targeting rapid delineation of a maiden Mineral Resource estimate for the Root Project.
- Drilling continues in parallel at Seymour with two drill rigs operating
“Commencingdrilling at Root is another significant milestone for our business. The initial focus at the advanced McCombe LCT pegmatite is confirmation and extension of known mineralisation, followed by rapid estimation of a maiden Mineral Resource estimate. We then plan to target other known spodumene-bearing LCT pegmatites at Root, including Morrison and Root Bay.”
- GT1 Chief Executive Officer, Luke Cox
McCombe drilling program at Root
Initial drilling at McCombe (22 holes for 2,500m) is targeted to confirm historical drilling and sampling. The second phase of drilling is then planned to test for extensions of the mineralised pegmatites in all directions, infill key sections and rapidly facilitate delineation of a maiden Mineral Resource estimate for the Root Project.
The McCombe LCT (Lithium-Caesium-Tantalum) pegmatite is the most advanced prospect at Root. Historical drilling completed by Ardiden Limited in 2016 saw six holes drilled, which intersected numerous pegmatites, generally dipping to the south and striking east-west. This drilling confirmed historical drill results and demonstrated the down dip continuity of the lithium mineralisation, including a key extensional intercept of 67m @ 1.75% Li2O (see GT1 ASX release dated 8 November 2021, Prospectus).

Field geologists continue to map the known LCT pegmatites, and determine their exposed lateral extents, across the broader Root Project. In combination with the recently acquired aerial photography, aerial geophysics and Lidar bare earth interpretations, a pipeline of initial targets for further field testing is being established at Root.

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).

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.

Drilling to Commence at Big Bell North Gold Project
HIGHLIGHTS
- Up to 4,500m aircore drilling program set to commence testing priority greenstone-splay, fault-hosted gold targets interpreted under cover at Big Bell North, along strike from the 5Moz Big Bell Mine and Garden Gully Projects in Western Australia’s world-class Murchison Gold Province.
- The Big Bell North tenements cover an extensive 337km2 area where little previous exploration has been carried out due to extensive regional soil cover and the historic lack of recognition of greenstone lithologies.
- Interpretation of recently completed aeromagnetic and gravity surveys has defined greenstone-splay fault priority drilling targets on both the eastern and western zones of the Big Bell North tenements.
- Drilling will initially focus on the Eastern Zone over a 9km north-south trend interpreted to be a faulted greenstone corridor (interpreted to be 700-1,400m wide) splaying from the regional scale Chunderloo Shear Zone. This setting is identical to the Garden Gully highgrade gold project, immediately along strike to the northeast, held by Ora Gold Ltd (OAU).
- The Eastern Zone drill targets have been further refined to align magnetic lows from the aeromagnetic survey with strong positive gravity survey responses, indicative of denser greenstones (dominated by prospective mafic rocks) in the interpreted shear zone. Shear zones associated with magnetic lows commonly coincide with quartz veining/alteration2.
- Soil sampling is also underway across the Western Zone target. Subject to results, a drilling program will follow to test bedrock targets for buried gold deposits at the Western Zone, where shallower cover exists.
- Anomalous gold results in the aircore drilling programs will be followed up with deeper RC drilling to test across the gold-anomalous structures.

Metals Australia Ltd CEO Paul Ferguson commented:
“The drilling program we are set to commence at our highly prospective Big Bell North gold project in Western Australia’s prolific Murchison Gold Province is the latest step in the Company’s aggressive push to unlock value from our suite of gold and critical mineral projects, which are all located in wellestablished mining regions in Australia and Canada.”
Our Big Bell North project, where there has been no modern-day exploration, has advanced rapidly during 2024 on the back of a methodical, phased exploration approach from our geological team. This started with an extensive fixed wing aeromagnetic survey covering over 5,200-line km which yielded two interpreted shear zones of significance.
We followed this up with detailed gravity survey work, which revealed the likelihood of greenstones within the shear zones. This is significant because gold mineralisation within the Murchison domain is often concentrated within such greenstone belts and is structurally controlled, thus enhancing the potential of the targets we are now set to drill.
In addition to Big Bell North, we continue to advance plans for an extensive soil survey and follow-on drilling program at the Warrego East copper-gold project in the Northern Territory, which is on track to commence later this year, ahead of the wet season, once permitting and land access arrangements are finalised.
We are also awaiting results and interpretation from two other recently completed exploration programs at Warrambie in the Pilbara, where our aircore drilling program has been completed; and our Corvette River project in Quebec’s James Bay region in Canada, where assay results from the phase one field program are imminent. Exploration at Corvette River is extensively focused on gold, silver, base metals (Cu-Pb-Zn) and lithium.
At our flagship Lac Carheil high-grade flake graphite project in Quebec, positive dialogue continues as we seek to build alignment on the project’s benefits with all stakeholders. Our significant cash reserves leave us well-placed to accelerate our various exploration programs as we continue striving to unlock the true value of our suite of projects in Australia and Canada.”
