Drill rig finance for exploration and geotech contractors

Price bands are wide because these machines do genuinely different jobs. Geotech and blasthole rigs generally run A$300,000 to A$800,000. RC and diamond exploration rigs — the track and truck-mounted units doing most of Australia's greenfields work — sit between A$500,000 and A$2.5 million depending on depth capacity, rod-handling automation and whether the unit is new. Underground jumbos start around A$1 million and rise from there once the drilling and bolting package is specified. Used examples of all three trade well below those figures, which is where most owner-operators actually buy.

The rig is only part of the spread. A productive job also needs a support truck, an auxiliary compressor or booster, water cartage, rod racks and a service ute — commonly another A$150,000 to A$400,000 on top of the rig. Financing the package as one facility is usually cleaner than funding the rig and then bleeding cash for the ancillaries: one settlement, one repayment, one asset schedule. Put the whole spread on the supplier quotes before approval rather than adding items afterwards, because a documented package finances far more smoothly than a rig plus a scatter of later receipts.

Drill rigs are not read like excavators. A rig on a double-shift program can accumulate five thousand hours a year, so an 18,000-hour machine is unremarkable rather than finished — what matters is what has been rebuilt, and when. Deck engine hours, carrier hours, rotation-unit hours and mast condition are separate questions, and a rig with a documented power-pack rebuild and a recent mast inspection presents better than a lower-hour unit with nothing in writing. Keep every rebuild invoice, NDT report and service record. On this asset class the paperwork is not administration; it is a large part of the value the lender is lending against.

Provenance is the second hurdle, and it is where deals stall. Plenty of Australian rigs are owner-built or heavily modified — a mast and drilling package fabricated onto a used truck chassis — which leaves a valuer with no comparable to reference and narrows the panel to lenders willing to send an assessor rather than rely on a book value. Serial numbers, compliance plates and a clean PPSR search are non-negotiable on private sales. Imported rigs add a further layer: most lenders will not draw down until the unit has landed, cleared customs and been inspected here, so the deposit wired offshore is your cash at risk for weeks.

Nothing moves a drilling application further than a signed contract, but lenders look past the metres to who is paying for them. A multi-year agreement with a producing mine or a tier-one contractor reads very differently from a program funded by a junior explorer's most recent capital raise, because the second can be cancelled by a soft equity market rather than by anything you did. Rate-per-metre schedules, standby rates and mobilisation fees all help evidence that the revenue is real. So does a spread of clients: a driller with three programs across two commodities is a materially better risk than one rig on one job.

We will not pretend this sector is steady, and neither will the lenders. Australian mineral exploration expenditure moves with commodity prices and the appetite for junior raisings, and the swings are sharp — the drilling boom that followed the gold and battery-metals run looked nothing like the pullback behind it. Assessors know this, which is why redeployment matters: what the rig does between programs, whether it can shift from exploration into geotech or water-bore work, and whether the business has traded through a downturn before. Operators who can answer that get better structures than operators who assume the current cycle simply continues.

Drilling is cash-hungry before it is cash-positive. Mobilising a rig and crew to a remote Western Australian or Northern Territory site means floats, fuel, camp costs, inductions and consumables — all paid weeks before the first progress claim goes out, and then carried again across thirty to forty-five day client terms. A profitable contractor can be badly short of cash in exactly the month a new program starts. Sizing a short-term or working-capital facility to the mobilisation budget is usually cleaner than draining reserves or stretching the equipment loan to cover costs it was never designed to fund.

Seasonality compounds it. Programs across the Pilbara, the Kimberley, the Top End and northern Queensland stop for the wet from roughly November to April, while the Goldfields and the southern states run closer to year-round — one reason so much of this market is concentrated in Western Australia. If your work is northern, the repayment schedule has to survive a quiet quarter without heroics. Some lenders will consider structured or seasonally weighted repayments where contract history supports it, and drillers who already own rigs outright sometimes release equity against them to fund a mobilisation rather than borrowing unsecured.

Most rigs are financed under a chattel mortgage, and at these ticket sizes the structure does real work. Your business owns the rig from settlement and the lender registers security over it, so the asset sits on your balance sheet and, in general terms, a GST-registered buyer may be able to claim the GST on the purchase price as an input credit on the next BAS. On a A$550,000 rig that GST component is roughly A$50,000 — a material cash-flow event within a quarter of settlement. Ownership may also open depreciation options. Both depend on your entity and turnover, so confirm the treatment with your accountant before relying on it.

Term and balloon need more care here than on mainstream plant. Rigs work for fifteen years or more with rebuilds, but lenders rarely term past five to seven years and many cap the asset's age at the end of the term, which can quietly shorten what is available on an older unit. Balloons tend to be conservative because the resale market is thin — the buyers are other drillers, and there are not many of them, least of all at the bottom of a cycle. Where financials are not current, low-doc structures exist in general terms for straightforward purchases, usually with a larger deposit and a narrower panel.
