Sandvik to Supply 15-Unit Underground Fleet at Karowe Mine

Sandvik has received orders from Lucara Botswana to supply a 15-unit fleet of underground drills and loaders, plus parts and services, for the Karowe diamond mine in Botswana.

Sandvik has landed orders to supply a 15-unit fleet of underground drills and loaders to Lucara Botswana for the Karowe diamond mine, in a package that also covers parts and services. It is a modest headline in equipment terms and a significant one operationally: Karowe is one of the few diamond mines in the world attempting the jump from open-pit to underground production, and the machines being bought now are the ones that will do the digging.

The order was reported by Mining Technology. No value was disclosed for the fleet or the accompanying service commitment.

Why a diamond mine buys drills and loaders at the same time

Underground hard-rock mining runs on a repeating cycle: drill the face, charge and blast it, then muck out the broken rock and haul it away. Drills and loaders are the two halves of that loop. Ordering both together, in a single 15-machine package from one supplier, tells you an operator is standardising a fleet rather than trialling equipment — one parts catalogue, one training regime, one set of service technicians on site.

The inclusion of parts and services in the same order matters more than it sounds. Underground availability is the number that decides whether a development schedule holds. A machine that is down waiting for a component is not just idle capital; it stalls the entire cycle behind it. Tying supply and support into the same contract is how operators in remote jurisdictions try to buy uptime rather than just iron.

For Sandvik, the commercial logic runs the same direction. Equipment sales are lumpy and cyclical; aftermarket parts and service revenue is recurring and higher-margin, and it is attached to the installed base for the life of the fleet. Every underground package delivered today is an annuity for the next decade of rebuilds, consumables and technician hours.

Karowe’s move below the pit

Karowe, in Botswana, is best known for producing exceptionally large, high-value stones — the kind that make headlines individually rather than as carats per tonne. That output profile is precisely why an underground project is worth attempting. Open pits get uneconomic as the strip ratio climbs, meaning more waste rock has to be moved for each tonne of ore. When the resource continues at depth and the ore is valuable enough per tonne, sinking underground infrastructure to reach it can beat digging an ever-wider hole.

Diamond mines are unusual underground candidates. Most underground operations chase a metal with a quoted market price; a diamond project chases a distribution of stone sizes and qualities, which makes revenue harder to model and financing harder to secure. Delivering a mobile fleet is one of the later, more tangible milestones in that sequence — it comes after the shafts, declines and ventilation are far enough along to justify putting machines to work.

What the order does not tell us is timing. Neither the delivery schedule nor the ramp-up profile was disclosed, and readers should not assume the fleet arrives all at once. Staged deliveries matched to development progress are the norm on projects of this type.

What the order says about underground equipment demand

Fleet orders of this size are a useful read on where mining capital is actually being spent, as opposed to announced. Underground development is capital-intensive and slow, so operators only commit to machine packages when the financing and the schedule are firm enough to absorb delivery slots. A 15-unit order is a decision that has cleared a board.

The broader pattern across the sector has been a shift of spending toward depth and complexity: the easy near-surface ore is worked out, and the next tonnes sit further down. That favours suppliers with underground-specific product lines — low-profile loaders, development and production drills, and the automation and remote-operation layers that increasingly ride on top of them. Botswana adds a jurisdictional angle: the country’s economy is deeply tied to diamond output, so extending the life of a producing asset carries weight beyond the operator’s own accounts.

What to watch next

• Disclosed order value. Neither the equipment nor the service component has been priced publicly. Any subsequent disclosure would frame how material this is to Sandvik’s mining segment book.
• Delivery and commissioning dates. The gap between order and first machine underground is where schedule risk lives.
• Automation content. Whether any of the 15 units are configured for teleremote or autonomous operation would signal how Karowe intends to run its underground levels.
• Follow-on orders. Trucks, ancillary equipment and ventilation gear typically follow a drill-and-loader package. A second tranche would confirm the underground build is progressing on plan.

The market backdrop on the day

The order landed into a quiet, marginally positive session for US equities. As of the last trade at 13:55 GMT on 14 August 2026, the S&P 500 tracker (NYSEARCA: SPY) was at $778.51, up 0.08% from the previous close of $777.88 and holding a tight day range of $777.66 to $778.60. The Nasdaq 100 proxy (NASDAQ: QQQ) traded at $733.42, up 0.18%, and the Dow 30 fund (NYSEARCA: DIA) at $538.21, up 0.06%.

None of that is a reaction to a single fleet order — Sandvik is a Swedish-listed industrial, and an unpriced equipment contract rarely moves an equipment maker’s shares. But the flatness is context worth noting: capital equipment orders in mining are being placed against a market that is neither pricing in a commodity boom nor a bust, and decisions like Karowe’s are being made on mine-specific economics rather than a rising tide.

The honest read on this news is narrow and useful. A producer with an unusual, high-value orebody has committed to the machines it needs to work that orebody from below, and has bought the support contract alongside them. That is a vote of confidence in the underground plan, expressed in the only currency that counts on a mine site: equipment on the ground.

Frequently asked questions

What exactly did Sandvik win at Karowe?

Sandvik received orders to supply a 15-unit fleet of underground drills and loaders to Lucara Botswana for use at the Karowe diamond mine. The package also includes parts and services, meaning aftermarket support is bundled with the equipment supply. No contract value was disclosed for either the machines or the service component.

How much is the order worth?

The value has not been made public. Neither the equipment portion nor the parts-and-services element was priced in the announcement, so it is not possible to say how material the order is to Sandvik’s mining equipment book without further disclosure from either party.

Why is Karowe going underground?

Open pits become uneconomic as the strip ratio rises — more waste rock must be moved for each tonne of ore. Where the orebody continues at depth and the ore is valuable enough, building underground access can be cheaper than widening the pit. Karowe is known for exceptionally large, high-value diamonds, which supports that economics.

Why do drills and loaders get ordered together?

Underground mining runs a cycle: drill the rock face, blast it, then load and remove the broken material. Drills and loaders are the two halves of that loop. Buying both from one supplier standardises spare parts, training and service, which helps maintain machine availability — the figure that usually determines whether a development schedule holds.

Why does the services element matter to Sandvik?

Equipment sales are cyclical and lumpy, while aftermarket parts and service revenue is recurring and attached to the installed base for the life of the fleet. Each underground package delivered creates years of consumables, rebuilds and technician work, which is why suppliers push to bundle support into the original order.

What should investors watch from here?

Four things: any disclosure of the order’s value, the delivery and commissioning timetable, whether any units are configured for teleremote or autonomous operation, and whether follow-on orders for trucks and ancillary underground equipment appear. A second tranche would indicate the underground build is tracking to plan.
