Major Drilling Group International just dropped A$50 million upfront — up to A$70 million with an earn-out — to buy Bunbury Drilling Company, a mine dewatering specialist in Western Australia. Through its Australian subsidiary, Major has acquired all issued and outstanding shares of BDC, a family-run outfit that’s been drilling in the region for over 70 years.
Here’s what this really means: a Canadian drilling major is paying real money for a niche, cash-generative business in a jurisdiction where the money actually gets spent. No regulatory approvals needed, funded from existing cash and debt facilities. Clean deal, modest size, sensible. That’s rare these days.
Now let’s talk about the earn-out, because that’s where deals get interesting. BDC has to average roughly A$18 million in annual EBITDA over three years to unlock the full A$20 million earn-out. So the sellers are confident — or the buyer did its homework. Either way, the structure protects Major Drilling from overpaying for a peak-cycle business. If Western Australia’s mining capex cycle cools, the earn-out evaporates and the effective price drops. That’s the buyer’s insurance policy, and frankly, every acquirer should demand one in this sector. Mining services is a cyclical trade dressed up as a growth story — always has been.
The strategic logic holds up under scrutiny. BDC drills exclusively for senior producers in Western Australia — BHP, Rio Tinto territory — which means Major is buying established relationships with the deepest-pocketed customers in the industry, not just eight rigs. Those relationships took the Linaker family three generations to build. You can’t drill your way into that kind of trust; you have to buy it.
Mine dewatering itself is a genuinely specialized niche, and that matters. As open-pit mines go deeper and water tables become a bigger operational and regulatory headache — particularly in Australia, where water licensing is a political sport — dewatering demand is structurally sound. This isn’t a hype cycle; it’s infrastructure-adjacent work tied to real commodity production. The technical complexity, purpose-built equipment, and skilled-crew requirements create barriers to entry. BDC’s fleet — four Schramm Fury 130s, three Versadrill V-2095 EXPs, and a Massenza MI12 — is described as high-end and well-maintained. Given how quickly specialized drilling equipment prices have inflated and how long lead times run these days, that fleet has real replacement value well beyond book.
This isn’t the first time we’ve seen this circus — a family business selling to a consolidator with promises of continuity and shared values. The press releases always read the same. BDC’s principal talks about honoring legacy and future generations making the company proud for another 70 years. Maybe. But the Linaker family just took the chips off the table, and there’s a reason sellers sell near the top or when the next generation doesn’t want the business. I’m not calling this a top in mining services — the commodity backdrop suggests otherwise — but seasoned deal watchers note that family sellers with 70-year track records tend to have good timing.
What’s encouraging is that BDC’s management stays on. Key-man risk in a relationship-driven business like this is the whole ballgame. If the crews walk and the senior producer contracts get renegotiated on hard terms, the earn-out dies and goodwill turns to impairment. Watch retention of the technical crews over the next 12 months — that’s the real leading indicator of whether this deal works, not the press release adjectives.
For Major Drilling CEO Denis Larocque, this fits an established playbook: specialized drilling, senior miners, diversified revenue. It’s a rational use of a balance sheet that’s been kept conservatively. A$70 million is pocket change against Major’s enterprise value, so the downside is contained. The upside is a foothold in a defensible niche with sticky customers.
From an investor’s seat: this is how disciplined capital deployment looks in the mining services space — small, strategic, structured with an earn-out, in a jurisdiction with rule of law. Compare that to the software-style multiples some drilling tech outfits have commanded, and the math here looks refreshingly sober. No narrative premium. Just rigs, crews, and contracts.
The risks worth pricing in: Western Australia is politically stable but cost-inflation prone — labor, diesel, parts. Mining capex is cyclical, and dewatering demand, while structurally supported, still tracks iron ore and gold production economics. And integration risk is real; majors have a long history of squandering acquired family businesses by smothering them in corporate process.
But on balance, this is a sound, unspectacular deal — and unspectacular is a compliment. Boring, well-structured acquisitions of cash-generative niche operators tend to compound quietly while the market chases the next shiny story. Major Drilling bought a durable business with locked-in customers and put most of the price at risk against performance. That’s a trade I can respect.
Whether BDC’s crews stay and the earn-out gets paid will tell us everything within three years. Keep an eye on that, not the headlines.
