About the Reconnaissance Field Trip
Lithium expert geologists Mr George Karageorge, Mr Pedro Kastellorizos along with Dr Darren Holden and Mr Ian Shackleton, (founding Geologist of the Global Lithium Resources ASX-GLI Archer Lithium deposit in Marble Bar) conducted a helicopter reconnaissance program over the Tambourah North Lithium Project, Haystack Well Lithium Project, and the Coondina South Lithium Projects.
MinRex Resources Limited Non-Executive Director Mr Karageorge commented:
“We are delighted to have identified spodumene within extensive outcropping pegmatites over 3 Projects areas. These rich spodumene stacked pegmatites have extensive width, strike and zoning which have all the hallmarks of a potential Archer Lithium Deposit.
MinRex is currently working on the first RC drill program to test the extensive stacked pegmatites over all 3 project areas with a view of signing the drilling contractor to undertake drilling over the projects once all approvals have been issued.
Tambourah North Lithium Project
Tambourah is located approximately 200 km south southeast of Port Hedland and 80km southwest of Marble Bar within the Pilbara Mineral Field. Access is via the Great Northern Highway or the Marble Bar – Port Hedland Road and the connecting Woodstock – Hillside Road. In 2013 Altura Mining Limited identified outcropping lithium mineralisation hosted within pegmatites. Initial investigation of the licence for rare metal mineralisation suggests that lithium is present as lepidolite in pegmatites located along the granite-greenstone margin. The dykes are up to 1 km in strike and 100 meters width and trend east-west across the dominant structural trend at Tambourah. 2
During the reconnaissance, a series of stacked pegmatites hosting spodumene striking 3300 over 1 km with approximately 50m in width were located within the greenstone belt. Acicular-lepidolite-albite-muscovite rich pegmatites were located on the contact zone between the Petroglyph Gneiss and Apex Basalt greenstone belt.

Top 5 Canadian Lithium Stocks of 2025
As the global push toward electrification accelerates, lithium remains a critical piece of the energy transition.
Continued oversupply remained a persistent headwind for lithium prices through the first half of 2025. Demand for the battery metal jumped 29 percent year-over-year in 2024, fueled by surging electric vehicle sales and rising power needs from sectors like data centers and heavy industry.
Fastmarket’s analysts expect lithium demand to grow 12 percent annually through 2030, supported by structural trends such as renewable energy integration and battery energy storage.
However, a rapid increase in global supply — particularly from China, Australia and South America — has driven prices to multi-year lows, raising concerns about project economics and the sustainability of new production.
Against this backdrop, Canadian lithium stocks are gaining attention as investors look for companies positioned to benefit from long-term demand growth while navigating short-term price pressure.
The Investing News Network breaks down the top-performing Canadian lithium stocks of 2025 for investors below. This list was created on July 22, 2025, using TradingView's stock screener, and all data was current at that time. Only companies with market caps above C$10 million for the TSX and TSXV and above C$5 million for the CSE are included.
1. NOA Lithium Brines (TSXV:NOAL)
Year-to-date gain: 58.82 percent
Market cap: C$488.32 million
Share price: C$0.30
NOA is a lithium exploration and development company with three projects in Argentina’s Lithium Triangle region. The company’s flagship Rio Grande project and prospective Arizaro and Salinas Grandes land packages total more than 140,000 hectares.
As NOA works to advance its flagship asset, the company brought on Hatch in April to lead the preliminary economic assessment (PEA).
The PEA will evaluate the project's economic and development potential with a target production of 20,000 metric tons of lithium carbonate equivalent (LCE) annually, with a scalable plant design that could double capacity to 40,000 metric tons per year.
NOA has also been working to secure a water source in the arid region through a drilling program targeting fresh water. In late June, the company discovered a fresh water source at the project, located near high-grade lithium zones in the project's northeast area. According to the company, the location means the water source could support future production facilities or evaporation ponds.
The well, drilled to 190 meters in the northern part of the property, is being tested and developed.

Top 3 US Lithium Stocks of 2025
As the global economy shifts toward electrification and clean energy, lithium has emerged as a cornerstone of the energy transition, and the US is racing to secure its place in the supply chain.
Lithium-ion batteries are no longer just critical to electric vehicles (EVs); they're becoming vital across sectors to stabilize power systems, particularly amid growing reliance on intermittent renewables.
According to Fastmarkets, demand for battery energy storage systems (BESS) is accelerating, driven by data centers, which have seen electricity consumption grow 12 percent annually since 2017.
In the US, where data infrastructure is heavily clustered, BESS demand from data centers alone could make up a third of the market by 2030, with a projected compound annual growth rate of 35 percent.
As the US works to expand domestic production and reduce import dependence, policy uncertainty, including potential rollbacks of EV tax credits and clean energy incentives, clouds the investment outlook.
Against this backdrop, the Investing News Network has created an overview of the top-performing US lithium stocks on the NYSE and NASDAQ. This list was created on July 22, 2025, using TradingView's stock screener, and all data was current at that time. Only companies with market caps above C$10 million were considered.
1. Sociedad Química y Minera (NYSE:SQM)
Year-to-date gain: 10.43 percent
Market cap: US$10.82 billion
Share price: US$40.64
SQM is a major global lithium producer, with operations centered in Chile’s Salar de Atacama. The company extracts lithium from brine and produces lithium carbonate and hydroxide for use in batteries.
SQM is expanding production and holds interests in projects in Australia and China.
Shares of SQM reached a year-to-date high of US$45.61 on March 17, 2025. The spike occurred a few weeks after the company released its 2024 earnings report, which highlighted record sales volumes in the lithium and iodine segments. However, low lithium prices weighed on revenue from the segment, and the company's reported net profit was pulled down significantly due to a large accounting adjustment related to income tax.
In late April, Chile’s competition watchdog approved the partnership agreement between SQM and state-owned copper giant Codelco aimed at boosting output at the Atacama salt flat. The deal, first announced in 2024, reached another milestone when it secured approval for an additional lithium quota from Chile's nuclear energy regulator CChEN.
Weak lithium prices continued to weigh on profits, with the company reporting a 4 percent year-over-year decrease in total revenues for Q1 2025.
2. Lithium Americas (NYSE:LAC)
Year-to-date gain: 9.67 percent
Market cap: US$719.1 million
Share price: US$3.29
Lithium Americas is developing its flagship Thacker Pass project in Northern Nevada, US. The project is a joint venture between Lithium Americas at 62 percent and General Motors (NYSE:GM) at 38 percent.
According to the firm, Thacker Pass is the “largest known measured lithium resource and reserve in the world.”
Early in the year, Lithium Americas saw its share rally to a year-to-date high of US$3.49 on January 16, coinciding with a brief rally in lithium carbonate prices.
In March, Lithium Americas secured US$250 million from Orion Resource Partners to advance Phase 1 construction of Thacker Pass. The funding is expected to fully cover development costs through the construction phase. On April 1, the joint venture partners made a final investment decision for the project, with completion targeted for late 2027.
Other notable announcements this year included a new at-the-market equity program, allowing the company to sell up to US$100 million in common shares.
3. Lithium Argentina (NYSE:LAR)
Year-to-date gain: 8.46 percent
Market cap: US$467.28 million
Share price: US$2.90
Lithium Argentina produces lithium carbonate from its Caucharí-Olaroz brine project in Argentina, developed with Ganfeng Lithium (OTC Pink:GNENF,HKEX:1772).
The company is also advancing additional regional lithium assets to support EV and battery demand.
Previously named Lithium Americas (Argentina), the company was spun out from Lithium Americas in October 2023.
While shares of Lithium Argentina spiked in early January to a year-to-date high of US$3.10, the share price has been trending higher since June 19 to its current US$2.90 value.
Notable news from the company this year includes its name and ticker change and corporate migration to Switzerland in late January and the release of the full-year 2024 results in March.
In mid-April, Lithium Argentina executed a letter of intent with Ganfeng Lithium to jointly advance development across the Pozuelos-Pastos Grandes basins in Argentina. The plan includes a project fully owned by Ganfeng as well as two jointly held assets majority-owned by Lithium Argentina.
The company released its Q1 results on May 15, reporting a 15 percent quarter-over-quarter production reduction, which it attributed to planned shutdowns aimed at increasing recoveries and reducing costs.
Overall, the production guidance for 2025 is forecasted at 30,000 to 35,000 metric tons of lithium carbonate, reflecting higher expected production volumes in the second half of the year.

Lithium Market Update: Q2 2025 in Review
The second quarter of 2025 brought more downward pressure for lithium prices, as values for lithium carbonate continued to contract, slipping to their lowest level since January 2021.
After starting the year at US$10,484.37 per metric ton, battery-grade lithium carbonate rose to a year-to-date high of US$10,853.85 on January 27. Prices sank through Q1 and most of Q2, bottoming at US$8,329.08 on June 24.
Lithium hydroxide followed a similar trajectory, with Fastmarkets analysts noting an 89 percent drop in prices for battery-grade lithium hydroxide monohydrate between 2022 and 2025.
“The lithium industry is definitely navigating a period of complexity,” said Paul Lusty, head of battery raw materials at Fastmarkets, at Fastmarkets' Lithium Supply & Battery Raw Materials conference in June.
“We're facing headwinds, no doubt, and we're also seeing quite a lot of negative or bearish sentiment widespread in the market, and I think at times, it's amplified by voices that really overlooked the phenomenal levels of demand that we're seeing in many aspects of the market.”
However, Lusty explained that despite facing a multi-quarter price slump, lithium’s long-term drivers remain robust, and are primarily driven by what he described as “mega trends.”
“The fundamentals are really still very strong, and these are anchored in some very powerful, mega trends that we see developing within the global economy; the urgent drive for climate change mitigation, the once in a generational shift in the global energy system, and also the rise of energy intensive technologies such as artificial intelligence,” he said.
Chinese expansions behind lithium oversupply
Although the long-term outlook for lithium remains positive, oversupply and market saturation have added headwinds during the first half of 2025. Demand, particularly from the electric vehicle (EV) sector, remains strong, but global lithium mine supply has outpaced it, rising by an estimated 22 percent in 2024 alone.
“We're forecasting similar year on year increases for both 2025 and 2026 equivalent to around 260,000 tons of additional (lithium carbonate) alone just this year,” explained Fastmarkets' Lusty.
“Chinese producers have been particularly aggressive in terms of expanding capacity.” Australia, Argentina and Chile are also driving growth alongside emerging producers like Brazil, and several African nations.
According to data from the US Geological Survey, mined supply from China increased 14.85 percent from 35,700 metric tons in 2023 to 41,000 in 2024, however an asterisk notes that the tallies are estimates, and exact numbers may be “withheld to avoid disclosing company proprietary data.”
For Fastmarkets, the total is likely higher.
“China has rapidly expanded its mining footprint, boosting domestic lithium output by 55 percent since 2023 and is on track to surpass Australia as the world’s top producer by 2026," said Lusty. “One of the most notable developments has been the rise of African supply that we started to see over the last two years,” said Lusty.
Africa’s emerging role in the lithium sector
The importance of African supply to the future lithium market was also the topic at Claudia Cook’s presentation, "The Lithium Market Shift: China’s and Africa’s Role in Redefining Supply."
During the 20 minute overview Cook explained that China is increasingly looking to African hard-rock lithium supply to provide feedstock for the country’s growing chemical segment.
So much so that by 2030 18 percent of global hard-rock lithium supply will originate from the continent.
Additionally, the continent will see a 170 percent uptick in hard-rock lithium supply output between 2025 and 2035, according to Cook, who attributes the massive expansion to China’s need to diversify its lithium sources due to domestic supply constraints. To facilitate this demand, China has invested heavily in African production.
“In 2025, 79 percent of African output will be China owned,” she said. “That percentage reduces down to 65 percent in 2035 however, with the increase in tonnage, even though there's a reduction in percentage, there'll be an almost doubling in terms of how much that's actually being put out.”
Regionally, Cook pointed to Zimbabwe and Mali as the country’s poised to see the most growth.
In 2025, Zimbabwe alone is expected to account for 70 percent of African lithium supply, though its share is projected to fall to 43 percent by 2035 as new countries come online.
Despite that shift, African output overall is set to rise significantly, with nations like the DRC, Ethiopia, and Namibia expected to begin production by 2035, said Cook.
Lithium demand surges, but prices lag
The rapid increase in supply has pushed prices to multi year lows, levels that are unsustainable and fail to incentivize new production. Despite this demand remains strong and is expected to grow.
According to the US Geological Survey, global consumption of lithium in 2024 was estimated to be 220,000 tons, a 29 percent increase from revised consumption of 170,000 tons in 2023.
Much of the demand story is attributed to soaring global EV sales, which were up 35 percent in Q1. Lithium consumption in this segment is projected to grow 12 percent annually through 2030.
“Globally, electric car sales this year are forecast to surpass about 20 million units in 2025 representing more than a quarter of all cars sold,” said Lusty.
Future lithium demand remains underpinned by deep structural shifts in global energy consumption.
“We’re witnessing extraordinary battery demand tied to the electrification of the global economy and the rise of renewable energy,” said Lustyt, pointing to surging electricity needs and the increasing role of storage solutions.
In 2024, global electricity demand rose by over 4 percent, adding 1,100 terawatt-hours to the grid, more than Japan’s total annual consumption. This marks the largest year-on-year increase outside post-recession rebounds and reflects broad trends such as greater electricity access, the proliferation of energy-intensive appliances, the expansion of artificial intelligence and data centers, and the shift to electric-powered heavy manufacturing.
Notably, 95 percent of future demand growth is expected to be met by renewables like solar and wind, further boosting the need for battery energy storage systems (BESS) to manage intermittency and stabilize grids.
“Batteries are now essential — not just for EVs, but to balance power systems across sectors,” Lusty added.
Data centers, in particular, are becoming a key growth driver. Since 2017, their electricity use has grown 12 percent annually, according to Fastmarkets, with the US seeing half its centers concentrated in five regional hubs.
By 2030, BESS demand from data centers alone could represent a third of the market, with a projected compound annual growth rate of 35 percent over the next five years.
Overall, lithium demand is forecast to grow 12 percent annually through 2030, underpinned by EV adoption, renewable integration, and digitalization. While China currently accounts for 60 percent of global demand, that dominance is expected to wane as other regions scale up.
“The long-term fundamentals remain intact,” he said, “and it's hard to envision a future where lithium isn’t central to the global economy.”
What's next for lithium in 2025?
After June saw prices slip to year-to-date lows, lithium saw a brief uptick in early July amid speculation about supply cuts from Australian miners Mineral Resources (ASX:MN,OTC Pink:MALRF) and Liontown Resources (ASX:LTR,OTC Pink:LINRF). However, gains were reversed after the rumors were denied.
In the US, policy uncertainty continues to weigh on sentiment. A rollback of EV tax credits under the Trump administration could spark a short-term sales bump, but longer-term support appears fragile.
New fair competition rules in China, aimed at curbing downstream dumping, have fueled speculation about broader impacts. While upstream effects are unclear, the policy contributed to July’s brief price rise.
“The nascency of the lithium market means that it is prone to be led by sentiment,” wrote Cook in a monthly update.
"We have especially seen this at play this month as prices ticked up momentarily mainly from rumors of supply cuts, highlighting how twitchy and reactive the market currently is," she continued.
"These rumors have since been denied … However, with healthy inventory levels and continued ramp-up of production, the reported supply cuts, even if they proved true, may not be enough to dip the market into a deficit.”

Ekin Ober on Why AI Could Be Mining’s Most Valuable Tool Yet
For Ekin Ober, bringing generative artificial intelligence (AI) to the critical metals sector through her work at Aethos Labs wasn’t just about technological innovation — it reshaped how she thinks about strategy and sustainability in mining.
Now a principal at Kinterra Capital, Ober applies that broad, cross-disciplinary lens to investment decisions, emphasizing the importance of digital fluency, stakeholder alignment and long-term viability.
Her experience helps her identify operational bottlenecks and social license challenges early — essential in guiding assets like nickel and copper projects from concept to production.
The Investing News Network (INN) sat down with Ober during the Fastmarkets Lithium Supply & Battery Raw Materials conference in Las Vegas, to learn more about the amalgamation of AI and mining.
While mining has long been viewed as a slow adopter of new technologies, Ekin Ober sees the tide turning — especially when it comes to AI.
However one of the largest learning curves has been educating industry stakeholders about the value of generative AI.
“They don’t need to be tech experts,” she said, “but it’s our job to show them how the tools work, and how their concerns can be addressed.”
As AI gains traction across the sector, she noted that even conservative markets are beginning to host dedicated discussions on the technology — a sign that change is accelerating.
How AI is being deployed
In addition to benefiting project planning through better modeling and digital twin, AI is making mining more efficient, safe and environmentally responsible.
In exploration, startups like KoBold use machine learning to analyze geological data, drastically cutting the time and cost of identifying potential lithium, copper, nickel and cobalt deposits
Operationally, majors such as Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO), BHP (ASX:BHP,NYSE:BHP,LSE:BHP) and Freeport-McMoRan (NYSE:FCX), deploy AI-powered autonomous haul trucks, drills and predictive maintenance systems that have slashed downtime and fuel use by up to 15 percent, while boosting throughput by 10 to 15 percent.
On the environmental front, AI tools optimize water management, monitor air quality and reduce waste, BHP’s Escondida mine reportedly saved over 3 gigaliters of water and 118 gigawatt hours of energy since 2022.
While AI isn't without its own controversy, usually arising from its energy consumption, Ober explained that AI integration can help reduce a mining site's overall energy intensity.
It is estimated that one billion daily AI prompts utilize 340 megawatt hours of electricity each day, while a mining site can use upwards of 1000 - 5000 megawatt hours. According to data from Natural Resources Canada, global mining operations consume 3 percent - 6 percent of the world's electricity.
Together, AI can help the mining sector better target deposits and reduce the amount of energy deployed.
“Drill holes (alone) use 3000 liters of diesel. And when you look at grinding, grinding ore is 70 percent of the mine’s electricity (consumption),” said Ober.
She added: So if you're using the technology for scans, you're able to use computer vision and scan a core, or look at the geography to reduce the number of drills, or the grinding exercise that you're going through, then it can actually save 1000s of hours of energy, conserving more than it consumes.”
From policy bottlenecks to permit approvals
This efficiency has made AI data sets appealing to governments as well. Through initiatives like DARPA’s CriticalMAAS and a collaboration with the US Geological Survey, AI models can now transform geologic map processing — from years to mere days — by automating georeferencing and mineral feature extraction.
These tools help rapidly assess hundreds of critical minerals across vast regions, accelerating decision-making and reducing exploration risk.
Meanwhile, the Pentagon’s AI-driven metals forecasting program, now managed by the Critical Minerals Forum, models supply, pricing and policy scenarios to bolster US sourcing strategies — especially for rare earths, nickel and cobalt.
For Ober, AI can also be integral to the often extended permitting process, while also implementing ESG goals and best practices. She explained that at Kinterra, AI is already playing a key role in streamlining permitting assessments, one of the most complex hurdles in mine development.
The firm has built a closed-loop system using large language models layered with its own criteria and values, including permitting stages, Indigenous engagement and community sentiment. The tool filters thousands of data points — from state filings to news releases and emails — extracting only what’s relevant.
Jurisdiction-specific updates are then summarized and delivered directly into Microsoft Teams, offering a real-time, digestible overview of key permitting signals.
“We need the company and the community to be engaged,” she said. “We take a very proactive approach. We engage very early on.”
Industry wide Ober sees AI improving the efficiency and transparency of mining permitting.
“One of the biggest concerns we hear is around security,” said Ober. “But we already trust companies like Google, Microsoft and Apple with sensitive data every day. If you’re using legitimate tools with strong policies in place, it’s manageable.”
Ober believes AI’s biggest value lies in its ability to accelerate slow, document-heavy government processes.
“Permitting can stall a project for years — not because of technical issues, but because no one has time to read the documents,” she said. “That’s where AI can help. Large language models can extract key information, layer in governance or environmental criteria and summarize it in a way that’s actionable.”
To address the risk of accuracy, Kinterra has designed its systems to generate traceable outputs.
“You can click a link and go straight to the original document and quote,” she explained, adding that this level of transparency is crucial for regulators and investors alike.
“It’s hard to commit capital when you don’t know if or when a permit will be granted,” she said. “AI won’t replace people, but it can get us to decision points faster — something the entire sector needs.”
