Ioneer Ltd just delivered a major update on its 100%-owned Rhyolite Ridge Lithium-Boron Project in Nevada. The company announced a huge 308% increase in Ore Reserves, along with fresh economic projections for the project.
Ioneer’s High-boron Strategy: Weathering the Weak Lithium Market
The miner revealed that the Ore Reserve has jumped by 186.6 million tonnes, bringing the total to:
- 246.6 Mt at 1,464 ppm lithium and 5,444 ppm boron,
- Containing 1.92 Mt of Lithium Carbonate Equivalent (LCE)
- And 7.68 Mt of Boric Acid Equivalent (BAE)
Nearly 48% of the Mineral Resource has now been converted into Reserve. Ioneer claims this makes Rhyolite Ridge the world’s largest known lithium-boron deposit.
The project is now expected to produce:
- 17,200 tonnes of LCE per year (life-of-mine average)
- 60,400 tonnes of boric acid per year
But for the first 25 years, the company plans to focus on high-boron ore (Hi-B), which would boost output to about 19,200 tonnes of LCE and 116,400 tonnes of boric acid annually.
Lithium’s Low-Cost Advantage Despite Market Woes
With lithium prices under pressure, Ioneer is leaning into boric acid as a stable revenue stream. Boric acid is used in everything from agriculture and construction to pharmaceuticals. For the first 25 years, it’s expected to account for about 25% of revenue.
It’s because of this boron credit, Rhyolite Ridge is now projected to sit in the lowest cost quartile for global lithium production:
- US$5,745/t all-in sustaining cost (battery-grade lithium hydroxide)
- C1 cost of US$3,858/t after boric acid revenue offsets

Capital Costs and Future Upside
Ioneer has also refined its cost estimates using detailed engineering. It now expects to spend US$1.67 billion to bring the project online, including a 10% contingency. Around 70% of engineering work is already complete.
The team has taken a more conservative stance on plant uptime and equipment maintenance, prioritizing long-term reliability over short-term gains.
Still, there’s room to grow. Recent testwork showed that reducing leach time from 3 days to 2 could boost acid yield by 7–14%, increasing lithium and boron output with minimal added costs. This faster process will be adopted once a new mine plan is ready.
Stockpiles and Stage 2 Potential
Hi-B ore will be the priority early on, which means a large amount of low-boron (Lo-B) ore will be stockpiled. This shift explains the lower life-of-mine mining cost ($9.90/t) compared to the first 25 years ($23.50/t). Much of the later production will come from these stockpiles.
Interestingly, Ioneer is exploring the option of using gravitational concentration to upgrade Lo-B ore by 1.4 to 2.0 times, potentially making it ideal for a future Stage 2 processing facility.
Rhyolite Ridge: A Key Lithium Project Powering the EV Future
Rhyolite Ridge is one of only two advanced lithium projects in the U.S. and is already fully funded up to the Final Investment Decision stage. Its valuable boron by-product and smart, cost-saving design stand out as a low-cost and sustainable operation.
Over its 26-year life, the project is expected to support battery production for more than 50 million electric vehicles. Thus, it’s all set to boost the U.S. lithium supply and will help reduce fossil fuel dependence. Overall, it supports the shift to low-carbon transport.
Furthermore, by processing materials directly on-site, Ioneer avoids the delays and costs of shipping to off-site facilities. This allows faster and more efficient production of lithium carbonate, which is a critical material for EV batteries.
Broadly speaking, Ioneer works closely with industry leaders and stakeholders who share a common vision: advancing electrification and cutting emissions.
Smart, Sustainable Operations
What sets Rhyolite Ridge apart is its world-class, environmentally focused design. The entire operation is built around sustainable practices:
- Low Water Use
Uses around 4,000 acre-feet of water each year — about the same as seven irrigation pivots. It means the mine uses very little water and recycles contact water as much as possible. - Lower Emissions
Relies on carbon-free energy and keeps greenhouse gas emissions to a minimum. Runs on a closed-loop steam system that generates green energy with zero carbon dioxide (CO₂) emissions. - It doesn’t rely on outside electricity from the grid.
- Smaller Footprint
No evaporation ponds. No tailings dam. Less impact on the environment.
Why Market Challenges Remain for Ioneer?
While the long-term vision looks strong, recent lithium price declines have made investors cautious. Earlier this year, Ioneer lost Sibanye-Stillwater as a joint venture partner, partly due to the weak pricing environment.

Despite this, Ioneer remains confident. Its strategy of front-loading boron-rich ore could provide valuable cost support, especially if lithium prices remain volatile. The company says its diversified product mix and large reserve base position Rhyolite Ridge as a top-tier global project.

How Climate Change Is Raising the Cost of Living
Americans are paying more for insurance, electricity, taxes, and home repairs every year. What many people may not realize is that climate change is already one of the drivers behind those rising costs.
For many households, climate change is no longer just an environmental issue. It is becoming a cost-of-living issue. While climate impacts like melting glaciers and shrinking polar ice can feel distant from everyday life, the financial effects are already showing up in monthly budgets across the country.
Today, a larger share of household income is consumed by fixed costs such as housing, insurance, utilities, and healthcare. (3) Climate change and climate inaction are adding pressure to many of those expenses through higher disaster recovery costs, rising energy demand, infrastructure repairs, and increased insurance risk.
The goal of this article is to help connect climate change to the everyday financial realities people already experience. Regardless of where someone stands on climate policy, it is important to recognize that climate change is already increasing costs for households, businesses, and taxpayers across the United States.
More conservative estimates indicate that the average household has experienced an increase of about $400 per year from observed climate change, while less conservative estimates suggest an increase of $900.(1) Those in more disaster-prone regions of the country face disproportionate costs, with some households experiencing climate-related costs averaging $1,300 per year.(1) Another study found that climate adaptation costs driven by climate change have already consumed over 3% of personal income in the U.S. since 2015.(9) By the end of the century, housing units could spend an additional $5,600 on adaptation costs.(1)
Whether we realize it or not, Americans are already paying for climate change through higher insurance premiums, energy costs, taxes, and infrastructure repairs. These growing expenses are often referred to as climate adaptation costs.
Without meaningful climate action, these costs are expected to continue rising. Choosing not to invest in climate action is also choosing to spend more on climate adaptation.
Here are a few ways climate change is already increasing the cost of living:
- Higher insurance costs from more frequent and severe storms
- Higher energy use during longer and hotter summers
- Higher electricity rates tied to storm recovery and grid upgrades
- Higher government spending and taxpayer-funded disaster recovery costs
The real debate is not whether climate change costs money. Americans are already paying for it. The question is where we want those costs to go. Should we invest more in climate action to help reduce future climate adaptation costs, or continue paying growing recovery and adaptation expenses in everyday life?
How Climate Change Is Increasing Insurance Costs
There is one industry that closely tracks the financial impact of natural disasters: insurance. Insurance companies are focused on assessing risk, estimating damages, and collecting enough revenue to cover losses and remain financially stable.
Comparing the 20-year periods 1980–1999 and 2000–2019, climate-related disasters increased 83% globally from 3,656 events to 6,681 events. The average time between billion-dollar disasters dropped from 82 days during the 1980s to 16 days during the last 10 years, and in 2025 the average time between disasters fell to just 10 days. (6)
According to the reinsurance firm Munich Re, total economic losses from natural disasters in 2024 exceeded $320 billion globally, nearly 40% higher than the decade-long annual average. Average annual inflation-adjusted costs more than quadrupled from $22.6 billion per year in the 1980s to $102 billion per year in the 2010s. Costs increased further to an average of $153.2 billion annually during 2020–2024, representing another 50% increase over the 2010s. (6)
In the United States, billion-dollar weather and climate disasters have also increased significantly. The average number of billion-dollar disasters per year has grown from roughly three annually during the 1980s to 19 annually over the last decade. In 2023 and 2024, the U.S. recorded 28 and 27 billion-dollar disasters respectively, both setting new records. (6)
The growing impact of climate change is one reason insurance costs continue to rise. “There are two things that drive insurance loss costs, which is the frequency of events and how much they cost,” said Robert Passmore, assistant vice president of personal lines at the Property Casualty Insurers Association of America. “So, as these events become more frequent, that’s definitely going to have an impact.” (8)
After adjusting for inflation, insurance costs have steadily increased over time. From 2000 to 2020, insurance costs consistently grew faster than the Consumer Price Index due to rising rebuilding costs and weather-related losses.(3) Between 2020 and 2023 alone, the average home insurance premium increased from $75 to $360 due to climate change impacts, with disaster-prone regions experiencing especially steep increases.(1) Since 2015, homeowners in some regions affected by more extreme weather have seen home insurance costs increased by nearly 57%.(1) Some insurers have also limited or stopped offering coverage in high-risk areas.(7)
For many families, rising insurance costs are no longer occasional financial burdens. They are becoming recurring monthly expenses tied directly to growing climate risk.
How Rising Temperatures Increase Household Energy Costs

The financial impacts of climate change extend beyond insurance. Rising temperatures are also changing how much energy Americans use and how utilities plan for future electricity demand.
Between 1950 and 2010, per capita electricity use increased 10-fold, though usage has flattened or slightly declined since 2012 due to more efficient appliances and LED lighting. (3) A significant share of increased energy demand comes from cooling needs associated with higher temperatures.
Over the last 20 years, the United States has experienced increasing Cooling Degree Days (CDD) and decreasing Heating Degree Days (HDD). Nearly all counties have become warmer over the past three decades, with some areas experiencing several hundred additional cooling degree days, equivalent to roughly one additional degree of warmth on most days. (1) This trend reflects a warming climate where air conditioning demand is increasing while heating demand generally declines. (4)
As temperatures continue rising, households are expected to spend more on cooling than they save on heating. The U.S. Energy Information Administration (EIA) projects that by 2050, national Heating Degree Days will be 11% lower while Cooling Degree Days will be 28% higher than 2021 levels. Cooling demand is projected to rise 2.5 times faster than heating demand declines. (5)
These projections come from energy and infrastructure experts planning for future electricity demand and grid capacity needs. Utilities and grid operators are already preparing for higher peak summer electricity loads caused by rising temperatures. (5)
Longer and hotter summers also affect how homes and buildings are designed. Buildings constructed for past climate conditions may require upgrades such as larger air conditioning systems, stronger insulation, and improved ventilation to remain comfortable and energy efficient in the future. (10)
For many households, this means higher monthly utility bills and potentially higher long-term home improvement costs as temperatures continue to rise.
How Climate Change Affects Electricity Rates
On an inflation-adjusted basis, average U.S. residential electricity rates are slightly lower today than they were 50 years ago. (2) However, climate-related damage to utility infrastructure is creating new upward pressure on electricity costs.
Electric utilities rely heavily on above-ground poles, wires, transformers, and substations that can be damaged by hurricanes, storms, floods, and wildfires. Repairing and upgrading this infrastructure often requires substantial investment.
As a result, utilities are increasing electricity rates in response to wildfire and hurricane events to fund infrastructure repairs and future mitigation efforts. (1) The average cumulative increase in per-household electricity expenditures due to climate-related price changes is approximately $30. (1)
While this increase may appear modest today, utility costs are expected to rise further as climate-related infrastructure damage becomes more frequent and severe.
How Climate Disasters Increase Government Spending and Taxes
Extreme weather events also damage public infrastructure, including roads, schools, bridges, airports, water systems, and emergency services infrastructure. Recovery and rebuilding costs are often funded through taxpayer dollars at the federal, state, and local levels.
The average annual government cost tied to climate-related disaster recovery is estimated at nearly $142 per household. (1) States that frequently experience hurricanes, wildfires, tornadoes, or flooding can face even higher public recovery costs.
These expenses affect taxpayers whether they personally experience a disaster or not. Climate-related recovery spending can increase pressure on public budgets, emergency management systems, and infrastructure funding nationwide.
Reducing Climate Costs Through Climate Action
While this article focuses on the growing financial costs associated with climate change, the issue is not only about money for many people. It is also about recognizing our environmental impact and taking responsibility for reducing it in order to help preserve a healthy planet for future generations.
While individuals alone cannot solve climate change, collective action can help reduce future climate adaptation costs over time.
For those interested in taking action, there are three important steps:
- Estimate your carbon footprint to better understand the emissions connected to your lifestyle and activities.
- Create a plan to gradually reduce emissions through energy efficiency, cleaner technologies, and more sustainable choices.
- Address remaining emissions by supporting verified carbon reduction projects through carbon credits.
Carbon credits are one of the most cost-effective tools available for climate action because they help fund projects that generate verified emission reductions at scale. Supporting global emission reduction efforts can help reduce the long-term impacts and costs associated with climate change.

Carbon credit project stewardship: what happens after credit issuance
A carbon credit purchase is not a transaction that closes at issuance. The credit may be retired, the certificate filed, and the reporting box ticked. But on the ground, in the forest, in the field, and in the community, the work continues. It endures for years. In many cases, for decades.
