SUMMARY OF MINING EXPLORATION FOR THE QUARTER
Bitterwasser Lithium Project
Assay results for the outstanding 32 drill holes from the 64-hole follow-up auger drilling campaign completed on 9 February 20224 over the Eden Pan was received during the quarter. All the drill holes commenced in the mineralised Upper Brown Clay Unit and every hole, except two drill holes where thin clay units were intercepted at the edges of the Eden Pan, were sampled from top to bottom up to a depth of 9.60m. Notably, the entire sequence of the drill holes sampled (i.e. Upper Brown Clay Unit and Middle Green Glay Unit) returned lithium mineralisation5.
The Middle Green Clay Unit, lithologically named the Middle-Unit (MU), comprises the dominant lithological unit from which the maiden Mineral Resource6 was derived. This green clay unit was intersected in 18 of the 32 drill holes from which assay results were received and extended from a depth of 1.4 m below surface to the maximum End-of-Hole (EOH) depth of 9.60m. A total of 43 holes from the 64-hole follow-up auger drilling campaign intersected the Middle Green Clay Unit at similar depths.

Kum-Kum Nickel Project Mineral Systems Approach Results
HIGHLIGHTS
- The Department of Earth Sciences at the University of Stellenbosch concluded a Minerals Systems Approach investigation over the Kum-Kum Ni-Cu-PGE Project Licenses
- During the investigation several historical documents containing exploration results over the Kum-Kum Project were discovered, which reported best historical borehole intersections from three boreholes drilled by Rio Tinto Exploration, Tantalite Valley Minerals and Southern Sphere between 1972 and 1976 as follows:
- 16.00 m @ 0.65% Ni, 0.16% Cu
- 6.00 m @ 0.61% Ni, 0.30% Cu
- 2.44 m @ 0.62% Ni, 0.30% Cu
- Historical core samples obtained were sampled and returned the first known record of PGE and Au mineralisation in the ultramafic units of the Tantalite Valley Complex. The best results indicated mineralisation of:
- 0.71% Ni, 0.28% Cu, 0.84 g/t Pd and 0.4 g/t Pt in orthopyroxenite
- 0.58% Ni, 0.30% Cu, 0.69 g/t Pd, 0.31 g/t Pt and 0.26% Au in orthopyroxenite
- The primary magmatic sulphides comprise of coarse-grained pentlandite, pyrrhotite, and chalcopyrite
- Whole rock geochemistry highlights the geochemical similarities between the TVC and the Kum-Kum complexes. The TVC crystallized as a mafic/ultramafic layered intrusion and likely from a primitive mantle-derived parental magma.
Philip le Roux, the CEO of Arcadia stated:
“Historical drilling results reporting high values of Nickel and Copper mineralisation attracted us to the Kum-Kum Project. From the work done by the team from the University of Stellenbosch it is evident that PGE and Au mineralisation is also present and that we are looking at a geological environment that possibly could contain a stratiform Ni-Cu-PGE disseminated sulphide ‘reef’ horizon. The prospect of possibly discovering a polymetallic (Ni, Cu, Au & PGE’s) deposit has increased the allure of the KumKum Project for us, which we will eagerly follow up with further exploration. The results of the study will assist the Company to focus its exploration efforts in order to define drill targets.”
Mineral Systems Approach Results
The Tantalite Valley Complex (TVC) has been subject to a geological study by a team from Arcadia and the University of Stellenbosch involving two field sampling campaigns (8 days; 94 field samples collected) augmented with detailed consideration of historical drill core segments (57 samples), and supporting data from historical records, hyperspectral mapping, and stream sediment sampling.
Collected field- and core- samples were subjected to a suite of analytical protocols including reflected- and transmitted-light optical petrography, whole-rock major and trace element chemistry, precious metal assays, sulphur isotope analyses, scanning electron microscopy with associated spectrometries and in-situ Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) of individual sulphide grains. Together, these results provide novel insights into the known mineralisation and prospectively of the TVC.
The TVC is a ~7 km long by 3.3 km wide and roughly oval-shaped mafic-ultramafic complex representing a fault-bound block inside a dextral Pofadder Shear Zone (PSZ) that cuts across southern Namibia. Existing geochronology places the TVC as a ~1.2 Ga intrusion and roughly coeval with a Kum Kum Klippe mafic complex that is located roughly 40 km south-east and along the strike of the PSZ.
Whole rock geochemistry highlights the geochemical similarities between the TVC and the Kum Kum suite, but with the former uniquely showing much stronger geochemical evidence for overwhelmingly cumulate rocks. This implies that the TVC crystallized as a significant mafic/ultramafic layered intrusion and likely from a primitive mantle-derived parental magma that originated from a metasomatized mantle.

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.

Results From First Drilling at Abbotts North Confirm LCT System
HIGHLIGHTS
- Assay results from Abbotts North confirm continuation of LCT system
- Focus shifts to targets identified to the north and east of previous drilling
- Field work over these newly identified areas has commenced
- Premier1 is fully funded for second phase exploration in these areas
A total of 11 RC holes for 1,623m were drilled to test the main outcropping pegmatites at the Buttamiah Prospect. Additional studies of the outcropping pegmatites in the larger Buttamiah Prospect area including fractionation vectoring using K/Rb ratios suggest the core of the system to be located to the east of the previous drilling.
In addition, the data indicate that LCT pegmatites occur within the granites to the north of the drill area. Further mapping and sampling of pegmatites in these areas as well as over the remaining tenement package has commenced. Focus is to delineate drill targets of higher grades and greater thickness that have the potential to form a significant lithium deposit within the existing LCT system.
Premier1 is fully funded for any subsequent phase two drilling program.
