Rent or Buy: The Honest Test
Renting is not a compromise for operators who cannot afford to buy. It is the correct decision whenever the equipment is needed for a defined period, when utilisation will be low, or when the operation has not yet proven the orebody it is built around.
The test is utilisation, not sentiment. A compressor working six days a week for three years should be owned. The same compressor needed for a four-month development campaign should be hired. Equipment sitting idle on a yard is capital doing nothing while it depreciates and rusts.
As a rough guide, if you will use the machine for less than three to six months, or for less than about a third of available hours over its life on your site, rental is usually the cheaper answer once you count maintenance, spares, downtime and the cost of the capital itself.
What Is Practical to Rent in Tanzania
Rental markets are deep for some categories and thin for others. These are generally available:
- Air compressors. The most commonly hired item in Tanzanian mining. Drilling campaigns need large air for defined periods and then do not
- Diesel generators. Widely available in a range of ratings, including for temporary construction and commissioning loads
- Dewatering pumps. Often needed urgently and seasonally, which is exactly what rental suits
- Drilling rigs with crew. Almost always contracted rather than owned by small and medium operators, and rightly so
- Earthmoving and haulage. Excavators, loaders and tippers, typically with operator
- Crushing and screening. Mobile units for defined campaigns, though availability is thinner
Process plant is a different matter. Mills, leach circuits and elution plants are rarely rented because they are configured to a specific ore and installed for years. If someone offers you a rented CIL plant, look carefully at why it became available.
Wet Hire and Dry Hire
The distinction determines who carries the risk, and it is the first thing to establish in any conversation.
Dry hire
You get the machine. You supply the operator, the fuel, the daily maintenance and the consumables. Cheaper per day, and sensible when you already have competent people and a maintenance routine. The risk is that abuse or neglect during the hire period becomes your bill at handback.
Wet hire
You get the machine, an operator, maintenance and usually fuel, priced per hour or per unit of output. More expensive per day, but the availability risk moves to the owner. For specialised equipment your team has not run before, wet hire is almost always the right call, because a rented rig destroyed by an inexperienced operator costs far more than the difference in rate.
What to Check Before Signing
- Availability guarantee and remedy. What percentage is promised, over what period, and what happens if it is not met. A guarantee with no remedy attached is not a guarantee
- Response time on breakdown. Hours or days, and from where. A four-hour response from Mwanza means something different in Sengerema than in Chunya
- Who supplies wear parts and consumables. The single most common dispute in dry hire
- Fuel. Included or not, and if included, at what consumption assumption
- Mobilisation and demobilisation. Frequently a large one-off cost, quoted separately or not at all
- Condition report at handover. Photograph and sign for the machine on arrival. Do this properly or you will pay for damage that predates you
- Minimum hire period and notice to return. Some agreements bill a full month after the first day of it
- Insurance. Who insures the machine, against what, and whether your policy actually covers hired-in plant
- Idle time. Whether you pay full rate while the machine sits waiting on your site works or your weather
Rates and How They Are Structured
Hire is usually quoted daily, weekly or monthly, with the effective rate falling sharply as the period lengthens. Long-term hire can approach a third of the equivalent short-term daily rate. Some equipment, particularly drilling, is priced per unit of output rather than per day, which aligns the owner's incentive with yours and is generally the better structure where it is available.
Rates are not published here because they move with fuel price, availability and season. Wet-season demand for dewatering pumps in the goldfields is a good example: the same pump costs meaningfully more in March than in August.
Lease to Own
Between renting and buying sits lease-to-own, where hire payments are credited against a purchase price. It suits an operation that expects to need the machine permanently but wants to prove the orebody or the cash flow before committing capital.
Read the arithmetic carefully. The total paid under a lease-to-own is usually well above the cash price, and that premium is the cost of the option. Sometimes it is worth paying. Check what happens if you stop, whether the credit is forfeited, and who owns the machine while payments continue.
Where Rental Goes Wrong
- Renting for years. Anything hired continuously beyond about a year should have been bought. Review long-standing hires annually
- Undersizing to save on rate. A generator that cannot start your mill motor is not cheaper, it is useless
- No condition report. Guarantees an argument at handback
- Ignoring mobilisation cost. On a remote site this can rival several months of hire
- Dry hire without the skills. If nobody on site can maintain it, the availability you are paying for will not materialise

Frequently Asked Questions
Is it cheaper to rent or buy mining equipment?
Rent if you need it for less than three to six months, or if utilisation will be below roughly a third of available hours. Buy if the machine will work continuously for years. The comparison must include maintenance, spares, downtime, storage and the cost of capital, not just the purchase price against the hire rate.
What is the difference between wet hire and dry hire?
Dry hire is the machine alone, with you supplying operator, fuel and maintenance. Wet hire includes operator and maintenance, usually fuel, and shifts availability risk to the owner. Wet hire costs more per day and is the safer choice for equipment your team has not operated before.
Can I rent a gold processing plant?
Rarely, and you should be cautious if offered one. Process plants are configured around a specific ore and installed for years, so a plant that suited the last owner's ore may perform poorly on yours. Modular plants are sometimes available on lease-to-own terms, which is a more sensible structure than short-term hire.
What happens if rented equipment breaks down?
That depends entirely on the agreement, which is why the response time and availability guarantee matter more than the rate. Under wet hire, repair is the owner's responsibility and you should not be paying full rate while the machine is down. Under dry hire the position is often reversed, so read the clause before you sign rather than after it stops.
