Frontier delivers high-energy, premium-quality thermal coal that industrial businesses across Southern Africa can count on: consistently, and at scale. For more than 20 years we have built our reputation on one uncompromising principle: we focus only on the highest-quality coal. We don't chase volume at the expense of grade. Every ton we supply is sourced from the richest seams, washed and processed to exacting standards, so our clients receive a reliable, uninterrupted supply of superior coal that keeps their operations running at peak efficiency.
Our team are recognised leaders in mineral resource mining, processing and development. We combine deep industry knowledge with innovative engineering, advanced fabrication techniques and uncompromising quality control, the same disciplines that have kept our clients loyal for years.
Strategically located for optimal service - Our operations are situated between Emalahleni and Middelburg in Mpumalanga, at the heart of South Africa's richest coal region. This prime position lets us service clients quickly and dependably, and to export across borders to Botswana, Lesotho, Mozambique and Eswatini - extending our reliability well beyond South Africa.
Built on relationships - We believe long-term partnerships, not one-off transactions, are what drive real value. Our team is dedicated to understanding each client's specific requirements and delivering fuel quality that measurably improves their performance and process efficiency. That commitment is why our coal has powered production lines across Southern Africa for many years, with consistently high client satisfaction.
Choose Frontier for unparalleled energy solutions - Partner with Frontier for premium thermal coal that drives efficiency, reliability and sustainability in your operations. We deliver energy solutions tailored to your needs - and we stand behind every ton.
Quality isn't one of our priorities — it's the only one. Frontier sources exclusively the highest-grade coal from the rich seams of Mpumalanga and washes and processes it to an exacting standard, so every single load delivers consistent, high-energy value. We never compromise on grade, and we never sell what doesn't meet it.
That discipline pays off in your operation. Cleaner, higher-energy coal burns hotter and more completely — so you burn less coal for the same output, move fewer loads, handle less ash and cut operating costs across your boilers and furnaces. The result is steadier combustion, higher efficiency, and real, measurable savings on every ton.
We guarantee our product quality - every grade, every load, every time.

We believe in transparent, competitive pricing. Frontier coal is A-Grade (28cv+) thermal coal, washed and processed to specification, with a typical quality of 28cv, 13% ash, 25–27% volatiles, 55%+ fixed carbon and 0.4–0.7% sulphur. Our headline grades start from:
| Product | Size | Price (from) |
| A-Grade Peas | 8 x 28 mm | R1 500 / ton |
| A-Grade Grains | 2 x 10 mm | R1 050 / ton |
| A-Grade Duff | 0 x 6 mm | R900 / ton |
Prices are quoted per metric ton, Free-on-Truck (FOT), exclude Value Added Tax (VAT), and are subject to Frontier's terms and conditions. Volume, delivery and specification all affect final pricing — contact us for a formal quote. Other product sizing and grades are available on request.
The same engineering capability we bring to clients, we apply to our own coal operation. Our Middelburg plant is the engine of Frontier's supply - where raw run-of-mine coal from Mpumalanga's seams is screened, washed, crushed and dewatered under strict quality control to deliver the consistent, high-energy product our clients rely on. Every stage is engineered, monitored and continuously optimised, so every ton that leaves our plant meets the Frontier standard.
Our processing capability spans four integrated circuits:
Screening is where raw coal is separated into precise size fractions — the foundation of a consistent, on-spec product. Frontier's screening circuits classify run-of-mine feed accurately and efficiently, removing oversize and undersize material and preparing each stream for washing and crushing. Accurate sizing at this stage is what allows us to deliver the tight product specifications our clients depend on, from Peas down to Duff.
Washing is at the heart of Frontier's high-energy value proposition. Using dense-medium and gravity-separation techniques, our washing circuits remove ash, rock and impurities from the coal, lifting calorific value and delivering a cleaner, higher-performing fuel. The result is more consistent combustion, lower ash handling and reduced operating costs for our clients' boilers and furnaces - the measurable benefits that set washed coal apart from raw product.
Crushing reduces washed coal to the exact size fractions our clients require, without generating excessive fines. Frontier's crushing circuits are engineered for controlled size reduction and high throughput, producing our full sized range : Peas (8 × 28 mm), Grains (2 × 10 mm) and Duff (0 × 6 mm) to consistent, repeatable specification.
Responsible water management is essential to sustainable coal processing. Frontier's flocculant plant treats process water by dosing flocculants that bind fine particles together, allowing solids to settle and clean water to be recovered and recirculated. This dewaters the fine slurry, recovers usable fines, reduces fresh-water consumption and minimises our environmental footprint - directly supporting our commitment to clean water (SDG 6) and responsible production (SDG 12).
