Background on Ignacio Mehech

During his tenure at Albemarle, a US-listed company with a current market cap of around US$6 billion as of 8^th April 2025, Mr Mehech played a pivotal role in driving production growth, strategic negotiations, and sustainability initiatives, significantly impacting Albemarle’s operations in Chile and the broader region. Since 2015, Chile has been Albemarle’s largest single operation – depending on market prices – accounting for 30 to 40% of its global production.

A landmark achievement under his guidance was securing the first-ever IRMA (Initiative for Responsible Mining Assurance) certification for a lithium operation worldwide at the Salar de Atacama plant-a testament to his commitment to environmental and social responsibility.

Previously to Albemarle, Mr Mehech has worked as a legal manager at Freeport-McMoRan, one of the largest copper and molybdenum producers in the world, with multiple assets around the globe. In Chile, it operates SCM El Abra, a joint venture with Codelco, located in Calama and where Mr Mehech was responsible for developing and leading the legal strategy for the business, assuring operational continuity, building relationships with regional authorities, indigenous and non-indigenous communities.

Ignacio Mehech Castellon, aged 42, has held the following directorships and/or partnerships in the past 5 years:

Mr Mehech currently holds no ordinary shares or other securities in the Company.

Notes

CleanTech Lithium (AIM:CTL, Frankfurt:T2N) is an exploration and development company advancing lithium projects in Chile for the clean energy transition. CleanTech Lithium has two key lithium projects in Chile, Laguna Verde and Viento Andino, and exploration stage project in Arenas Blancas (Salar de Atacama), located in the lithium triangle, a leading centre for battery grade lithium production.

The two most advanced projects: Laguna Verde and Viento Andino are situated within basins controlled by the Company, which affords significant potential development and operational advantages. All three projects have good access to existing infrastructure.

CleanTech Lithium is committed to utilising Direct Lithium Extraction (‘DLE’) with reinjection of spent brine resulting in no aquifer depletion. Direct Lithium Extraction is a transformative technology which removes lithium from brine with higher recoveries, short development lead times and no extensive evaporation pond construction.

Meeting rising metals demand with tech solutions

Global copper demand is expected to double by 2035, reaching approximately 50 million metric tons annually, driven largely by energy transition technologies, electric vehicles and infrastructure development.

But even as mining companies race to keep pace, challenges like declining ore grades, environmental restrictions and rising costs continue to limit production.

Maverick states that its proprietary lixiviant works at ambient temperatures and neutral pH levels, offering a safer, cheaper and more sustainable alternative to traditional acid leaching.

The technology enables the recovery not only of copper, but also valuable by-products such as molybdenum, gold, silver and even rare earths from a variety of unconventional sources — including tailings, smelter slag and coal fly ash.

According to Maverick, its LithX technology has demonstrated a range of benefits that could reshape the economics and the overall environmental footprint for metals processing.

For instance, the technology increases recovery rates at ambient temperatures, significantly reducing energy costs. It also eliminates the need for acid addition, offering a safer and more sustainable alternative to traditional methods.

In addition, Maverick notes that the process mitigates the risk of acid contamination and hazardous reagent exposure, enhancing worker safety — a key concern in traditional mining operations.

“We are pleased to announce our investment in and support of Maverick Metals,” said Nichola Eliovits, managing partner at Olive Tree Capital, in the company’s release. “We believe LithX has the potential to significantly increase the range of viable resources available to help alleviate global supply constraints.”

While copper remains a primary focus, LithX has shown versatility for a range of critical metals, such as high lithium extraction from spodumene and enhanced rare earths and gallium recovery from minerals like allanite and monazite.

Double hit: Tariff shock and OPEC+ supply surge

The catalysts for the broad decline are a one-two punch of a deepening trade conflict between the US and China, and a surprise production surge from OPEC+ nations.

Trump’s tariff announcement — described by JPMorgan (NYSE:JPM) as the ‘largest tax hike on Americans since 1968’ — has rattled global markets and sent oil traders into a panic over demand destruction.

Beijing has responded with defiance, promising to fight to the end and calling Washington’s demands “blackmail.’

At the same time, OPEC+ — the alliance of major oil producers led by Saudi Arabia and Russia — announced an unexpected increase of 411,000 barrels per day in May output, compressing three months of planned supply expansion into a single move. The boost comes after months of US pressure to increase supply and push down energy prices.

But the timing could not have been worse for American producers. Analysts say the combined impact of slowing global trade and higher supply of the energy fuel has left the American oil industry vulnerable. Prices have dropped below the US$65 threshold needed to sustain profitable drilling activity across much of the US.

According to the latest Dallas Federal Reserve energy survey, even operations in the Permian Basin — the lowest-cost production zone in the country — require crude to trade above US$61 to remain economically viable.

“You’re probably seeing more pauses of initial investment intention than the initial Covid shock. It’s really bamboozling,” Rory Johnston, a veteran oil analyst and publisher of the Commodity Context newsletter, told Heatmap.

“Everything else is really, really starting to grind to a halt, and you’re not seeing anyone jumping over themselves to ‘drill, baby, drill,’ despite the White House’s claims,” Johnston added.

Equity markets have punished energy companies accordingly. Oilfield services giant Halliburton (NYSE:HAL) shed 20 percent in a single week, while Nabors Industries (NYSE:NBR) lost 30 percent in just five days.

The oil majors fared slightly better, but still saw significant losses, with ExxonMobil (NYSE:XOM) down 10 percent, Occidental Petroleum (NYSE:OXY) down 15 percent and Chevron (NYSE:CVX) falling 13 percent.

Tariff fallout threatens global energy outlook

There is growing concern among market watchers that if economic activity continues to weaken under the weight of tariffs, further declines in both oil and gas demand are likely.

Crucially, many of the countries most affected by Trump’s tariffs — particularly in Southeast Asia — were previously projected to drive the bulk of oil and energy demand growth over the next decade.

Vietnam, Cambodia and four other Southeast Asian nations were hit with tariffs exceeding 45 percent, prompting concerns that their economies could stall or contract.

“The macro concern is that if these tariffs stay where they are, this is in a global recession, if not a depression-making place,” Johnston elaborated in his conversation with Heatmap. “And given that the highest tariff rates are on Asia in particular, and that’s where all growing oil demand is, it’s not good for oil.”

Meanwhile, US producers are grappling with higher costs for drilling inputs due to tariffs on steel, aluminum and other industrial goods. Johnston explained in a Bluesky post that drillers have reported a 30 percent spike in the cost of tubular steel pipe, a critical material for oil and gas wells, since Trump implemented a 25 percent steel tariff in February.

So far, OPEC+ officials have not signaled any plans to curb output again.

For now, the market remains volatile, and producers are in a state of limbo. Despite early promises of energy dominance and renewed drilling, Trump’s policy choices have left the sector reeling.

“The administration’s chaos is a disaster for the commodity markets. ‘Drill, baby, drill’ is nothing short of a myth and populist rallying cry. Tariff policy is impossible for us to predict and doesn’t have a clear goal,” one executive told the Dallas Fed last month.
