How we operate — and why it matters
Built to leave
less behind.
Sustainability at Metabore is not a reporting exercise. It is the natural consequence of doing the work properly — extracting precisely, disturbing minimally, and restoring completely.
Our philosophy
The method is the sustainability strategy.
Micro Mining is inherently a sustainable discipline. When you extract only what is valuable, access the orebody through the smallest possible opening, and use clean energy to do it — you are not making concessions to sustainability. You are simply doing the work well.
We don't believe environmental responsibility requires compromise. In the case of narrow-vein underground mining, precision and sustainability point in exactly the same direction. A smaller tunnel requires less energy to ventilate. Electric equipment eliminates diesel emissions underground. Selective extraction produces less waste. These outcomes reinforce each other — and they reinforce the economics.
"The most sustainable mine is the one that takes only what it came for."
Electrification
Clean power underground. Already operating.
Metabore operates a fully electric underground equipment fleet. This is not a target or a transition plan — we have the equipment and we use it. Electric machinery eliminates diesel particulate matter from enclosed workings, removes combustion heat from narrow tunnels, and dramatically reduces ventilation requirements. The result is a cleaner, safer, and more efficient operation at every level.
Electrification and narrow-vein precision mining reinforce each other directly. Smaller tunnels need less air volume to stay safe — and with no diesel combustion, that ventilation demand drops further still. Less ducting. Less fan infrastructure. Less energy to run it. The tunnel is small by design, and the equipment keeps it that way.
On each project, our intent is to achieve net zero emissions. Electric equipment underground, renewable energy sources at surface where available, and a minimal operational footprint that limits emissions at every stage. This is not an offset strategy — it is an operational one.
- ✓No diesel exhaust or particulate matter in underground workings
- ✓No combustion heat — critical for safety and comfort in narrow tunnels
- ✓Reduced ventilation demand — smaller infrastructure, lower energy consumption
- ✓Significant reduction in carbon emissions across the operational footprint
- ✓Lower fire risk underground — no stored fuel, no ignition sources
- ✓Quieter operation — reduced noise impact at surface and for personnel
- ✓Compatible with solar and renewable energy at remote project sites
- ✓Net zero emissions target on each project — operational, not offset-driven

Tunnel design
Small by intention. Not by constraint.
In conventional underground mining, large tunnels are a necessity of scale — built to accommodate large diesel equipment, high ventilation volumes, and bulk ore movement. In Micro Mining, the tunnel is sized for the task. Development headings are kept as narrow as the geology and the equipment allow.
This matters for sustainability in ways that compound. A smaller tunnel disturbs less rock, generates less spoil, requires less concrete and ground support, and demands significantly less energy to ventilate. Over the life of a project, the cumulative difference in material consumption, energy use, and waste generation is substantial.
Narrow headings also improve safety. Less exposed rock face means less risk of ground instability. Shorter bolt patterns. More manageable working environments. The precision of the tunnel mirrors the precision of the extraction — and both are better for it.
Less rock disturbed
Development headings follow the ore, not a predetermined profile. Only the rock that needs to come out does — reducing spoil volumes, waste handling costs, and surface disposal requirements.
Lower energy consumption
Ventilation is one of the largest energy costs in any underground mine. Narrow headings combined with electric equipment cut ventilation demand significantly — reducing both energy use and the infrastructure required to deliver it.
Improved ground stability
Smaller openings require less ground support and present less exposed face. This reduces the risk of unplanned ground movement, lowers support material consumption, and improves the working environment for personnel.
Reduced surface infrastructure
Narrow development means less ore and waste movement, which means smaller surface handling facilities. The portal, waste pad, and processing footprint are all proportionally reduced — and the land around them remains undisturbed.
Sustainability principles
Six things we commit to on every project.
01 · Electrification
Clean energy underground, always.
We operate electric equipment in all underground workings. No diesel exhaust, no particulate matter, no heat load from combustion. This is standard practice on every Metabore project — not a future commitment.
02 · Precision
Extract only what is valuable.
Selective extraction means less waste rock, less processing, less energy, and less surface disposal. Sustainability and grade discipline are the same decision — made correctly every time ore is taken from the ground.
03 · Footprint
Occupy only what is necessary.
Surface infrastructure is limited to the absolute minimum required to operate. Portal, ventilation, processing, and personnel facilities — nothing more. The surrounding land is not a staging area. It is left as we found it.
04 · Waste
Minimise what leaves the vein.
Narrow-vein selective stoping produces far less waste rock than bulk methods. What waste is generated is managed on-site where possible — used as backfill underground rather than stockpiled at surface.
05 · Safety
A safe mine is a better mine.
Electric equipment eliminates fire risk from diesel fuel underground. Narrow headings reduce exposed ground. Smaller crews working with precision equipment in well-managed environments are safer crews. Safety and sustainability are inseparable.
06 · Rehabilitation
Plan the end from the beginning.
Rehabilitation is designed into every project from the first permit application. Bonds are held, milestones are defined, and outcomes are measurable. Underground portals can be sealed cleanly — and they will be.
Our commitment in practice
Sustainability built into the process, not bolted on.
Rehabilitation plan prepared, bonded, and submitted before any ground is broken. Environmental baseline documented. Community and regulatory engagement completed.
Fully electric equipment fleet operating underground — zero diesel exhaust, zero combustion heat. Ventilation on demand. Real-time air quality monitoring. Renewable energy at surface where available. Net zero emissions target pursued on every project.
Regular environmental monitoring and reporting to regulators and stakeholders. Surface footprint reviewed and reduced as operations evolve. Water management active throughout.
Portal sealed, surface restored, rehabilitation milestones met and verified. The site returns to its pre-mining state — or better. Closure is not an afterthought. It is the final deliverable.
