Epiroc: Why I Stopped Chasing the Lowest Quote (And You Should Too)

Stop comparing just the purchase price of an Epiroc rock drill or a Scooptram. That's the fastest way to blow your annual budget. Over the past six years managing a seven-figure procurement budget for a 200-person mining contractor, the lowest quote has cost us more in hidden fees and lost productivity roughly 4 out of 10 times.

How I Learned This Lesson (The Hard Way)

In Q2 2024, we were in the market for a new Epiroc Boomer S2 jumbo drill. We narrowed it down to two vendors. One offered a price that was 12% lower than the other (a savings of roughly $40,000 on the base unit). It seemed like a no-brainer. My gut said something was off, but the numbers looked clear.

Here's what the spreadsheet didn't show: the cheaper quote excluded the standard automation package (RCS) that the other vendor included. It also didn't factor in the longer lead time on a critical part—the drill feed. The 'savings' evaporated when we paid for expedited shipping to keep our mine site operating. In the end, that 'cheap' option cost us more in downtime than we saved. That was a $12,000 lesson (ugh).

Since then, I don't even look at the base price first anymore. I look at the total cost to own and operate the equipment for the first three years. That's the real number.

The Hidden Costs of Epiroc Equipment (That No One Talks About)

When comparing an Epiroc 1650 drill rig to a competitor's model, or even between two Epiroc dealers, you need to dig deeper. The base list price is just the entry fee. The real costs that Bureau of Mines data shows affect total ownership are:

• Automation integration. Does the price include the Mobilaris digital solution or an interface for Automine? Adding it later can cost 20-30% more than if it's ordered as a package.
• Service network density. You might find a 'cheaper' quote from a dealer in Chile, but if you're operating in Kalgoorlie, the cost to fly in a technician and get a part delivered will obliterate that savings. I've seen this happen.
• Training and commissioning. Some quotes include two weeks of on-site training for your operators (crucial for complex rigs like the Boomer). Others charge a daily rate for that. Checking these details in the fine print is tedious but essential.

(I made a checklist for this. Note to self: I really should digitize and send to my team.)

My Three-Step TCO Method for Mining Equipment

I don't have a perfect formula, but after six years of tracking every invoice from every vendor (we currently work with 8 different suppliers for drilling tools alone), I've developed a simple three-step process that works:

1. Identify the 'Invisible' Items. Ask for a quote that specifically lists setup fees, software licensing (like OptiMine), and the cost of the first year of service support. If they won't provide it, that's a red flag.
2. Calculate Your Downtime Risk. For a critical machine like a Boltec rock bolting rig, what is the cost per hour of it being down? If a cheaper spare part has a 10% higher failure rate, the math becomes clear instantly.
3. Get a Reference for That Specific Model. Not just for the brand. Find another contractor who has run a specific model like the Pit Viper 271 or the ST14 Scooptram in an environment similar to yours. Ask about their parts consumption in year two. That's the real data.

Between you and me, vendors hate these questions because they expose the gaps in their quotes.

When a 'Cheaper' Quote Might Actually Work

I don't want to sound absolutist. There are specific times when I can justify a lower upfront cost:

• A non-critical asset. For a utility vehicle that won't stop production, a cheaper third-party part might be fine.
• A known, short-term job. If you need an Epiroc breaker for a 3-month demolition project, you don't need the same level of service contract as for a permanent mine installation.
• When you have surplus in-house capability. If your in-house maintenance team is exceptional and can handle the repairs, the risk of buying a 'base model' is lower.

But for a high-capital asset like a new mining truck or a production drill, chasing the lowest price is a gamble I learned not to take. The savings you see on the invoice upfront will be paid back, with interest, in your maintenance budget.
