ARI recovers antimony and other critical minerals from historic mine waste in South Africa, builds a secure supply for the United States and its allies, and gives the land back to nature and the community.
Scroll to see a pile become land
Satellite screening and field geologists map historic tailings across Africa, with a focus on South Africa's antimony districts. Every candidate is sampled by an accredited laboratory.
Licensed local partners reprocess the pile into antimony concentrate. Nothing new is dug. Tracking technology makes every shipment traceable, from the pile to a Western refinery.
The hazard is removed, dust and runoff are controlled, and the ground is rehabilitated for nature and the community.
Watch how ARI turns a century-old problem into a resource the West needs.

Antimony is a critical mineral for defense, energy and industry, and most of the world's supply runs through China. For the United States, a secure supply is a question of national security. ARI is a US company building an alternative source, with no Chinese involvement at any point in the chain.
Old piles leave dust, polluted runoff and unusable ground behind. Recovering what is left in them pays for cleaning them up, for landowners, for communities and for the environment.

We start by sourcing critical minerals already processed by local South African producers, and grow into recovering our own. Each phase pays for and de-risks the next.
Antimony concentrate from licensed South African producers, lab-tested and delivered under long-term contracts.
Agreements with landowners and asset holders. Licensed partners reprocess historic piles and rehabilitate the land.

Two sides of one supply chain: the land and the people in South Africa, and the buyers and capital in the United States.
An old pile on your land can become income and restored ground.
Local jobs, training, and cleaner air and water close to home.
Material without the capital or plant to process it.

Antimony is a critical mineral for the United States and its allies. Their defense, energy and industrial base cannot run without it, and today they import almost all of it.
Western processing capacity is thin, and the largest supplier has already used exports as leverage. For buyers and governments alike, a reliable supply is now a strategic priority.
The United States lists antimony as a critical mineral and imported 91% of what it used in 2025. China is the largest producer and processor. In December 2024 it banned antimony exports to the United States; the ban was suspended in November 2025 for one year. American buyers need sources they can rely on.

Through much of the twentieth century, processing methods left a meaningful share of antimony in the waste. South Africa's historic antimony districts hold that material today, above ground, without the need for a new mine.
The West is short of processed antimony, and governments are stockpiling it. Concentrate that South African producers have already processed can be tested, shipped and delivered to a Western refinery quickly, long before any new mine could produce.

The plan
ARI is a US company building a China-free antimony supply from South Africa, and cleaning up the land it comes from. This is how we get there.

Antimony in South Africa is concentrated in two ancient greenstone belts in the north-east of the country. Our first area of interest is the Antimony Line, between Gravelotte and Leydsdorp in Limpopo. Both belts are within reach, by road and rail, of the Indian Ocean ports of Maputo, Richards Bay and Durban.
Home of the Antimony Line, one of the best-known antimony-gold districts in the world. Historic processing left a meaningful share of the antimony in the waste.
One of the oldest mining districts in the world. Parts of the belt carry antimony-bearing ore, and small historic mines left piles on private farms that have never been reprocessed.
Each phase pays for and de-risks the next.
Many South African producers already have processed concentrate but no route to Western buyers. We locate it, test it and deliver it.
We secure historic piles and reprocess them with licensed partners, from sampling to rehabilitated land.

Targets, not promises. Every step depends on sampling results and agreements.
We are putting a great deal of energy into shortening every step of this timeline.
Intensive work on the ground with community leaders, landowners and partners, and visits to candidate sites. We build each project around shared interests: returns for investors, and jobs and restored land for the community.

Phase 1 supply contracts and the first tailings agreement.
Retreatment starts with a licensed partner, about six to eight months after site selection.
Financed against offtake contracts and proven results.
Antimony is less than one percent of a pile. The rest is not reburied. Once it is cleaned and tested, it goes back to the community as building material.
We recover the antimony for Western refiners, and clean what remains of arsenic and other historic toxins. An accredited laboratory tests it before anything leaves the site.
The clean sand passes to a local community trust, within South Africa's B-BBEE framework, together with our local partner.
ARI seeds an industrial block press and cement. The community owns and runs its own plant, making affordable building blocks for schools, clinics and homes.
Nothing is wasted, and the value stays in the region. The community block plant is a concept we are developing with our local partner.

We are building long-term partnerships on both sides of the supply chain. Find the part that fits you.
Many farms and game reserves carry old mine waste on their land. It can become a source of income and a cleaner property.
We want every project to leave the area better than we found it.
For liquidators, trustees and license holders who have material but not the capital or plant to process it.
We are looking for experienced geologists and metallurgists who know South Africa's greenstone belts.
For refiners, processors and industrial users who need antimony concentrate from a Western supply chain.
For investors, lenders and trade-finance partners looking at critical minerals and Western supply chains.
