Terra is set to mine millions of tonnes of magnetite at Extension Hill
Terra is Mining
In May of 2023, Terra Mining entered into contracts to operate the Extension Hill Magnetite mine in the Mid-West region of Western Australia outside Perenjori.
A Tier 1 resources project, Extension Hill has an inferred resource of 341 million tonnes with a DTR of 37.3%, and a concentrate grade of 65.2% iron. All Stage 1 project milestones, including state and federal approvals, have been completed. Offtake agreements with Baowu, the largest steel producer in the world, have been secured.
Road and rail contracts have been agreed, with the first shipment of ore expected in Q4 of 2023. Current production planning calls for 3M tonnes of direct shipping ore across 2024 and 2025, scaling up to 5M tonnes in 2026 following completion of the dry processing facility onsite. Initial workforce planning sees upwards of 200 personnel on-site post construction, which is projected itself to create over 200 jobs.
Extension Hill is a landmark in the story of our business.

Magnetite
Magnetite is a vital component in steelmaking. As the world transitions to a lower-carbon footprint within industry and materiel manufacturing, magnetite is positioned to continue its rise as a mineral in demand.
Magnetite, with a higher iron content than the traditional hematite ore mined widely throughout Australia, is a key element in the production of low impurity, high quality steel products and derivatives.
Magnetite ore is typically processed post-production, transforming into a high iron grade concentrate with acutely low levels of impurities and imperfections. Further processing by offtake partners of this concentrate then produces magnetite pellets, ready for steel production by furnace or direct reduction.
It’s unique post production process makes for a seamless product that is ready to produce high-grade steel, particularly when compared to hematite (conventional) iron ore that is mass produced.
Magnetite attracts a premium in today’s market.

Vital component in steelmaking
Magnetite is highly prized for its ability to produce high-grade steel with low impurities.

low carbon production
Produces high grade concentrate with lower carbon intensity than hematite iron ore.

A mineral for the future
Magnetite is highly prized today, and will continue to be so as industry changes.

Mine Approvals
With all State, Federal, environment and regulatory approvals in place, Terra has already commenced mining at Extension Hill.
All approval barriers have been cleared, allowing us to proceed to production with confidence.
Land use rights are in place, and all environmental approvals are standing. This includes provision for Native Title, as well as heritage agreements that cover site sensitivity.
Extension Hill is a long-term project with low risk.
Extension hill Infrastructure
Road, Rail and Port infrastructure is established for Extension Hill. We’ve strategically engaged key partners to ensure fulfilment from pit to port.
Production
Current production planning calls for 3M tonnes of direct shipping ore across 2024 and 2025, scaling up to 5M tonnes in 2026 following completion of the dry processing facility onsite.
Terra is now a major player on Australia’s magnetite scene.
With the completion of on-site processing plant (scheduled for commissioning inside 24 months), Terra will become the fourth largest producer of magnetite on the continent.
Our track-record for production has been a hallmark of Terra Mining since its inception. We’re confident of steady, sustainable production throughout the life of the mine.
Think magnetite. Think Terra Mining.
4th largest magnetite miner
Terra will become Australia’s fourth largest miner of magnetite.
6M p/a tonnes scheduled
Production schedules call for rapid scaling up from 3m tonnes to 5m tonnes
TERRA - A major player in magnetite
Australia has a rich history in the production of raw materiel for steel construction.
Terra is proud to join this pantheon of market-proven providers of magnetite.
Over time, we seek to expand this footprint and climb the ladder as we transition to becoming a globally recognised provider of mining across magnetite and other minerals.
Extension Hill is forecast to have production of upwards of 5-6m tonnes of magnetite at the peak of operations.
Jobs
Throughout the construction phase, infrastructure development calls for upwards of 180 FTE jobs to service Extension Hill’s project planning. These will cover areas such as civils development, mining plant construction, pit development and other site infrastructure requirements.
Several employees and contractors are already on-site as construction ramps up, with the processing plant due for completion in 2026.
At peak production, Extension Hill will require a large workforce forecast to be upwards of 270 personnel. These jobs will cover a range of different disciplines, including plant and equipment operation, drilling, blasting, hauling and processing facility management.
We will have on-site fixed maintenance capacity, as well as permanently stationed geology and quality teams. As production scales up, so will the workforce requirements across both FTE and contractor verticals.
Diversification equals opportunity. Where there’s minerals, there’s mining.
