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 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.

Forward Water Technologies
Overview
Forward Water Technologies (TSXV:FWTC) is helping lithium mining companies and other industries reduce their environmental impact through its innovative wastewater treatment technology that enables industrial operations to reduce liquid waste volume by up to 95 percent.
Environmental, social and governance (ESG) ratings continue to be a key business strategy for organizations as they impact public perception and partnership possibilities. For water-intensive industries, such as mining, sustainable wastewater management is critical.
Transformative wastewater technologies are critical for both businesses and the world’s population. In fact, unless sufficient progress is achieved, UNICEF and WHO estimate that 1.6 billion people will be without access to safe drinking water by 2030, and 2.8 billion will be without access to safe sanitation and hygiene. Water treatment technologies can disrupt current trends and improve global access to safe drinking water.
Through its Forward Osmosis (FO) technology, Forward Water is providing an environmentally friendly alternative to traditional wastewater disposal. Traditionally, wastewater disposal requires transporting untreated wastewater for deep well disposal or high-intensity thermal treatment.
Forward Water’s FO system is installed at the client site, and wastewater is treated to reduce waste volume and produce valuable clean water for reuse in the manufacturing process. Then, the significantly reduced volume of wastewater is transported and disposed of, significantly saving on transportation and disposal costs.
The FO technology targets three massive sectors: industrial wastewater, mining and food manufacturing. Forward Water’s unique and patented FO technology achieves high-rate water extraction within a low-energy continuous process. The process reduces waste and allows up to 95 percent water recovery, ready for reuse.
Forward Water’s Li-FO™ technology is ideal for lithium-brine mining operations, allowing mines to “fine tune” brine sources to improve concentration by up to 20 times. This results in improved recovery and makes lower-concentration brines economically viable. Forward Water is currently embarking on an early development testing project to further evaluate and refine the technology’s viability in lithium mining.
In 2023, the company’s wholly owned subsidiary, Forward Water Technologies Inc., licensed specific intellectual property from FUJIFILM Corporation to solidify the protection of its water treatment technology platform.
CleanTech Lithium (AIM:CTL,Frankfurt:T2N,OTC:CTLHF) has contracted FWT to provide advisory services for the support and development of CleanTech Lithium's direct lithium extraction (DLE) process in Chile. The collaboration will use FWT’s industrial forward osmosis system in the hyper-concentrating of CleanTech Lithium's eluate and its conversion into battery-grade lithium carbonate through Conductive Energy's DLE process.
Howie Honeyman, CEO, explained in an interview how the company’s technology can improve lithium mining operations. “A lot of lithium being mined today around the world is coming from underground aquifers that store the lithium brine. The challenge is that the lithium is surrounded by other minerals and salts, requiring chemical ‘tweezers’ to pluck out that lithium. What we can do is, at multiple places in that process, we can concentrate that lithium-containing water stream, which makes it far easier for these miners to handle the volumes they need to extract that lithium.”
An experienced management team with technical expertise leads the company towards further refining and deploying its technology. The team includes experts in materials science, chemistry and engineering. Additional experts in corporate administration and financing round out the leadership team to lead the company toward its goals.

Key Project
Forward Osmosis Water Treatment
Forward Osmosis is a naturally occurring process in which water is spontaneously drawn across a membrane when one solution is higher in salt concentration than the other. The difference in salinity, known as the osmotic gradient, creates a low-energy water treatment process.
Forward Water Technologies has leveraged the naturally occurring process to innovate its patented, three-step FO technology, enabling a 95 percent wastewater reduction and 95 percent water recovery.
Project Highlights:
- Patented Three-Step Process: Forward Water Technologies FO process achieves low-energy and high-rate water extraction with a unique three-step design:
- Water Extraction: Water is drawn across the FO membrane into a salt draw solution. The combination of the patented draw solution and unique membrane “locks” the draw solution on one side of the membrane, creating a true closed-loop process.
- Water/Salt Separation: Next, a switchable water salt (SWS) achieves water/salt separation as low-grade heat is applied, and it phases from liquid to gas. As the gas leaves the solution, clean water is left behind. The energy necessary for this step is often found in many facilities in the form of waste heat.
- Salt Draw Reconcentration: Finally, as the gas leaves the solution, it is captured within the closed-loop system and is passively cooled, causing it to phase back into liquid form as an SWS. The SWS liquid is collected and recycled back to the front of the membranes in the water extraction step, creating a continuous process.
- Widely Applicable Water Treatment: The low-energy process allows organizations across several industries to improve water reclamation and reduce wastewater by up to 95 percent. Additionally, the process allows for up to 20 times concentration, making the process amenable to lithium-brine extraction and other potential applications.
- Significant Cost Savings: The primary value proposition for the FO process is cost reduction in wastewater transportation and disposal. With the process in place, more water is reclaimed for reuse in manufacturing, which reduces the raw volume of wastewater that must be transported and disposed of.
