STOP BUYING A DRILL RIG. START BUYING A COMPLETE DRILLING SOLUTION.
So you've bought an RC drill rig.
Excellent.
Where's the compressor?
And the drill rods?
Hammer?
Bits?
Cyclone?
High-pressure hoses?
Sampling equipment?
Tooling?
Critical spares?
Suddenly the drill rig isn't looking quite as complete as it did on the quotation.
This is one of the biggest mistakes companies can make when buying exploration drilling equipment.
They buy the machine.
What they actually need is the drilling system.
For Reverse Circulation and Air Core drilling, that distinction matters enormously.
Compressed air has to be matched to the drilling application.
The drill string has to work with the rig.
The hammer and bits have to suit the hole.
The cyclone and sampling system have to handle the returns.
And somebody needs to make sure the entire package works together before it disappears into the middle of nowhere.
That's why Cylinder Exploration Drilling approaches RC and Air Core equipment differently.
Tell us what you're drilling first.
Then we'll build the equipment package around it.
What Equipment Do You Actually Need for RC Drilling?
Let's start with the obvious question.
A complete RC drilling operation can require:
RC drill rig
High-pressure air compressor
RC drill rods
Inner tubes
RC hammer
Drill bits
Subs and adaptors
High-pressure air hoses
Air manifolds
Cyclone
Sample splitter or sampling system
Breakout tooling
Rod handling equipment
Lubrication equipment
Consumables
Critical spare parts
Maintenance tools
Support equipment
Fuel
Personnel
And that's before we've discussed freight, commissioning, training or getting the equipment to the drill site.
So when someone asks:
“How much does an RC drill rig cost?”
They're asking an important question.
But not necessarily the most important one.
A better question is:
“How much will the complete system required to execute my drilling programme cost?”
That's the number that actually matters.
The RC Drill Rig Is the Centre — Not the Whole System
The rig is still fundamental.
It provides the rotation, feed, pullback and mechanical platform required to advance the hole.
CED manufactures RC drilling platforms for different applications, including our conventional RC range and mobile SFM Series configurations.
But choosing the rig should start with the drilling requirement.
How deep are you planning to drill?
What hole diameter?
What geology?
What ground conditions?
How many metres?
Single shift or double shift?
What access is available?
What mobility does the project require?
Those answers affect far more than the drill rig.
They influence almost everything else in the package.
The Compressor Can Make or Break the RC Package
RC drilling runs on compressed air.
That makes the compressor one of the most important equipment selections in the entire system.
Not an accessory.
Part of the drilling system.
The air has to travel down the drill string, operate the drilling system and transport the sample back to surface.
The required pressure and airflow depend on factors including:
Hole depth
Hole diameter
Ground conditions
Water inflow
Hammer requirements
Drill-string configuration
Target production
A compressor that's too small can limit drilling performance.
A compressor that's substantially oversized may introduce unnecessary cost, fuel consumption and mobilisation weight.
The objective isn't:
Buy the biggest compressor you can find.
It's:
Match the air package to the drilling programme.
16 Bar? 20 Bar? 35 Bar?
This is where things get interesting.
Different drilling applications can require very different air packages.
CED can configure drilling solutions using compressors across approximately the 16–35 bar range, depending on the drilling method and project requirements.
Air Core operations may operate with a different pressure and airflow requirement from deeper RC drilling.
Higher-pressure RC applications may require a 35-bar-class compressor.
And in some drilling conditions, additional air capacity may be required.
The correct answer depends on the hole.
This is exactly why CED doesn't believe the compressor conversation should happen after the rig has already been purchased.
Rig and air need to be engineered together.
Do You Need One Compressor or Two?
Another good question.
Again:
It depends.
Some RC applications can operate effectively with a single correctly selected compressor.
Other programmes, particularly where greater air volume is required, may use multiple compressors connected through a suitable manifold arrangement.
But two compressors aren't automatically better than one.
They cost more.
Consume more fuel.
Need more maintenance.
Create additional logistics.
And add another machine to the mobilisation.
CED's approach is to look at the actual air requirement and configure accordingly.
Don't buy two compressors because somebody said RC rigs need two compressors.
Don't buy one because it's cheaper.
Work out what the hole needs.
Then supply the air.
RC Drill Rods: Not Just Pieces of Pipe
Once you've got the rig and air package sorted, you'll need something to drill with.
RC drill rods are specialised dual-wall components designed to allow the drilling medium and sample return system to function correctly.
The drill-string configuration needs to match the drilling system.
That means considering:
Rod diameter
Inner tube
Thread type
Rod length
Hole diameter
Hammer compatibility
Planned depth
Required rod quantity
And quantity matters.
If your deepest hole is 200 metres, don't order 150 metres of rods and rely on positive thinking.
But equally, don't automatically buy hundreds of metres of unnecessary drill string if the programme doesn't require it.
The package should reflect the planned holes, operating requirements and sensible contingency.
Then You Need the Hammer
For conventional RC hammer drilling, the hammer is doing the unpleasant work at the bottom of the hole.
That means hammer selection matters.
Different hammers and drilling configurations are suited to different applications, hole sizes and operating conditions.
The hammer also needs the correct air supply.
Again, we're back to system compatibility.
Compressor.
Rig.
Rods.
Hammer.
Bit.
They are not five unrelated purchases.
They are one drilling system.
And the Bit Is Going to Wear Out
Bits are consumables.
Rock tends to be rather inconsiderate about that.
Bit life depends on geology, operating parameters, bit design and drilling conditions.
A drilling package therefore needs a sensible inventory of bits for the expected programme.
Too few and you risk stopping production.
Too many and you've tied up money in inventory that may sit unused.
CED can configure initial consumable quantities around the expected metres, ground conditions and project location.
The more remote the project, the more important contingency becomes.
Because an extra bit sitting in the container is relatively cheap.
A complete RC crew waiting several days for one is not.
What Does the RC Cyclone Actually Do?
Now we've drilled the material.
We need to deal with the sample.
The cyclone forms an important part of the RC sampling system, helping separate the sample material from the returning air stream so it can be collected for geological analysis.
From there, the sampling setup may incorporate splitters or other sample-handling equipment depending on the programme.
This matters because RC drilling isn't simply about making a hole.
It's about producing a useful geological sample.
Poor sample handling can undermine the entire reason you're drilling.
The rig gets the glory.
The sample is what the geologist actually wants.
Hoses: Boring Until You Don't Have the Right Ones
Nobody launches an exploration company because they're passionate about high-pressure air hoses.
At least, we hope not.
But RC systems require suitable hoses and connections between compressors, manifolds and drilling equipment.
Those hoses need to be appropriate for the pressures involved and configured correctly for the package.
The same applies to:
Connections
Fittings
Manifolds
Adaptors
Clamps
Associated air-system components
These are exactly the sort of components that can be overlooked when equipment is purchased from several unrelated suppliers.
And they're exactly the sort of components capable of stopping an expensive drilling system.
Small component. Large headache.
Tooling Is Part of the Package
Drill strings need assembling.
And eventually they need coming apart again.
That means suitable breakout and handling tooling needs to be included.
Depending on the system, the package may require:
Rod spanners
Breakout tools
Subs
Adaptors
Hoisting equipment
Handling tools
Service tools
This is another area where compatibility matters.
A tool that nearly fits is not a tool.
It's an argument waiting to happen at the drill site.
Then Come the Spares
RC drilling equipment works hard.
Dust.
Vibration.
Heat.
Pressure.
Long shifts.
Remote environments.
Eventually components wear.
The intelligent question isn't whether equipment will ever require maintenance.
Of course it will.
The intelligent question is:
Did you send the parts required to maintain it?
CED can configure critical and operational spares around the equipment package and expected drilling programme.
That can include service items, wear components and selected critical parts that could otherwise create substantial downtime.
Location matters enormously here.
A project drilling near established industrial infrastructure has one supply-chain profile.
A remote programme hundreds of kilometres from the nearest serious workshop has another.
Your spare-parts inventory should reflect that reality.
What About Air Core Drilling?
Now things change.
Air Core is often used for relatively shallow exploration and reconnaissance drilling.
The method can offer a fast and relatively economical way of testing near-surface geology where conditions are suitable.
But it still needs a complete drilling system.
That can include:
Air Core-capable drill rig
Compressor
Air Core rods
Cutting equipment
Sampling equipment
Hoses
Tooling
Consumables
Spares
Support equipment
The equipment specification is different from deeper conventional RC.
That's the point.
RC and Air Core should not automatically receive the same package.
The method changes.
The depth changes.
The air requirement changes.
The tooling changes.
The support requirement can change.
CED configures accordingly.
When Does Air Core Make Sense?
Air Core can be extremely useful for early-stage mineral exploration where relatively shallow geological information is required.
That can include:
Reconnaissance programmes
Geochemical exploration
Shallow mineralisation
Regolith investigations
Early-stage target testing
Large programmes requiring relatively rapid shallow drilling
For exploration companies trying to understand a large area before committing to deeper RC or diamond drilling, Air Core can form an important part of the exploration sequence.
It isn't a replacement for every drilling method.
It is another tool.
Use the drilling method that answers the geological question.
When Does RC Make More Sense?
RC becomes particularly valuable where projects require deeper drilling and efficient sample production through harder formations.
It is widely used across:
Gold exploration
Copper exploration
Lithium exploration
Critical-mineral exploration
Resource definition
Grade-control drilling
Mine exploration
RC can deliver high drilling productivity in suitable formations and provides samples that can be logged and sent for analysis.
Again, the correct drilling system depends on what the project is trying to achieve.
Don't start with the equipment catalogue.
Start with the geology.
Air Core First. RC Next. Diamond After That?
In some exploration strategies, different drilling methods can complement one another.
Air Core may be used to test shallow targets across a broad area.
RC can then investigate selected targets at greater depth.
Diamond drilling can provide intact core for detailed geological, structural and geotechnical information.
That's not a universal sequence.
But it demonstrates something important.
Exploration drilling methods aren't necessarily competitors.
They're tools used to answer different questions.
CED's equipment range is built around that reality.
Diamond.
RC.
Air Core.
Underground.
Water well.
Remote-access platforms.
The drilling method should follow the project requirement.
Remote RC Creates a Different Problem
Now take the RC package away from established infrastructure.
Suddenly the equipment itself is only one challenge.
The compressor needs to reach site.
Fuel needs to reach the compressor.
Rods need transporting.
Tooling needs moving.
Samples need handling.
Spares need to be available.
Maintenance support needs to reach the rig.
This is where CED's wider SFM Series becomes particularly relevant.
Our 6×6 exploration platforms and modular support systems are being developed around one central idea:
If the drill rig can reach the target, the support system needs to reach it too.
SFM7300: RC, Air Core and Auger Mobility
The CED SFM7300 is our 6×6 mobile platform developed around shallow RC, Air Core and Auger drilling applications.
Rather than treating mobility as an afterthought, the drilling system is built around a Toyota Land Cruiser 79 Series 6×6 platform.
That creates an interesting option for remote programmes where conventional truck-mounted equipment may be less practical.
But the SFM7300 still needs support.
Which brings us to trailers.
Bring the Compressor With You
The CED SFMTS modular trailer system can be configured around different exploration support requirements.
That can include compressor packages.
For RC and Air Core operations, this allows CED to develop a mobile drilling combination where the rig and air system are considered together.
SFM7300 in front.
SFMTS behind.
Compressor aboard.
Now the drilling system is considerably more mobile.
And that's the bigger CED strategy.
We're not simply trying to build an off-road drill rig.
We're trying to make the complete drilling operation mobile.
Add the SFM7600 Support Vehicle
Then there is the SFM7600.
CED's 6×6 exploration support platform can be configured around requirements such as:
Fuel
Water
Consumables
Tools
Critical spares
Workshop equipment
Exploration logistics
Put that beside a mobile RC or Air Core system and the fleet starts becoming much more self-contained.
Drilling platform.
Compressor.
Support vehicle.
Trailer.
Consumables.
Personnel.
That's a very different proposition from simply shipping a rig.
How Many Metres Are You Actually Drilling?
This question should influence almost everything.
A 1,500-metre reconnaissance programme and a 20,000-metre RC campaign do not need identical inventories.
Expected metres affect:
Rod quantities
Bit quantities
Hammer requirements
Spare-parts inventory
Maintenance planning
Consumables
Staffing
Logistics
Support equipment
This is why one-size-fits-all drilling packages don't make much sense.
CED wants to know the programme.
Then we configure around it.
Single Shift or Double Shift?
Another seemingly simple question with significant consequences.
A rig operating one shift per day experiences a different utilisation profile from equipment drilling around the clock.
Double-shift operations increase:
Operating hours
Fuel consumption
Maintenance frequency
Consumable usage
Staffing requirements
Spare-parts demand
If the client intends to run the equipment hard, the package needs to reflect that from the beginning.
Don't configure a 24-hour drilling operation using assumptions based on an eight-hour day.
The Cheapest Quote Isn't Necessarily the Cheapest Drilling System
This is where procurement becomes interesting.
Supplier A has the cheapest rig.
Supplier B has a cheap compressor.
Supplier C has rods.
Supplier D has a cyclone.
Supplier E has the hammer.
Fantastic.
Now somebody has to make sure it all works together.
Then organise freight from five locations.
Then work out which supplier is responsible when two components don't interface properly.
Saving money on individual equipment lines can quickly become expensive if the complete system isn't coordinated.
CED's proposition is different.
Let us quote the drilling package.
Not simply the machine.
One Supplier Means One Point of Responsibility
This doesn't mean CED physically manufactures every nut, hose and component inside every drilling package.
That's not the point.
The value is in integration.
The rig needs to work with the compressor.
The compressor needs to provide the required air.
The rods need to match the drilling configuration.
The hammer needs to match the rods and bit.
The cyclone needs to suit the sample system.
The hoses need to connect everything.
The tooling needs to fit.
The spares need to correspond with the actual equipment.
Somebody needs to look at the entire picture.
That's the job we're offering to do.
Then Put It in the Container
Once the equipment package is finalised, it still has to reach the project.
CED can coordinate international logistics for complete drilling packages.
That may involve:
Equipment consolidation
Container loading
Export preparation
Sea freight
Air freight for selected items
Inland logistics
Mobilisation planning
This matters particularly for international exploration projects.
Having the rig arrive in one shipment and critical tooling arrive three weeks later is not an efficient mobilisation strategy.
We want the package to arrive ready to be commissioned and put to work.
Commissioning Matters
New drilling equipment needs to be set up correctly.
CED can provide commissioning support when the equipment reaches site.
That allows the system to be inspected, assembled and tested under operating conditions.
It also creates an opportunity to train client personnel on correct operation and maintenance.
The objective is simple:
Get from container to drilling as quickly and sensibly as possible.
Or CED Can Supply the Crew
Some clients don't want to become drilling contractors.
They want control of their drilling assets while experienced personnel operate them.
CED can support projects with:
Drillers
Supervisors
Mechanical fitters
Commissioning personnel
Operational management
That creates another model.
The exploration company owns the equipment.
CED provides the drilling expertise.
For suitable long-term programmes, that can create a very different cost structure from continually outsourcing every metre to a traditional drilling contractor.
Gold, Copper, Lithium or Critical Minerals — The Principle Is the Same
The commodity doesn't determine whether good equipment planning matters.
Gold projects need reliable samples.
Copper projects need reliable samples.
Lithium projects need reliable samples.
Critical-mineral projects need reliable samples.
Different geology may require different drilling methods and equipment.
But the principle remains:
Build the drilling system around the geological objective.
Not around whichever rig happens to be cheapest this week.
Built for Global Exploration
CED supplies drilling equipment and operational support internationally.
Africa.
South America.
Asia-Pacific.
The Middle East.
Central Asia.
Every region brings different challenges.
Infrastructure.
Climate.
Terrain.
Importation.
Fuel availability.
Local technical support.
Freight.
Remote access.
The drilling package needs to acknowledge those realities.
A system being mobilised into remote West Africa may need a different spare-parts strategy from one operating near an established mining centre.
A Pacific island project has different logistical constraints from a desert exploration programme.
Same drilling principles. Different operational reality.
So What Should You Tell CED?
If you're planning an RC or Air Core drilling programme, give us the useful information.
Project location.
Drilling method.
Expected metres.
Typical hole depth.
Maximum hole depth.
Expected geology.
Hole diameter.
Groundwater conditions if known.
Single or double shift.
Site access.
Expected mobilisation date.
From there, CED can start configuring the equipment package.
Rig.
Air.
Drill string.
Tooling.
Sampling.
Consumables.
Spares.
Support.
Logistics.
People.
That's a much more productive starting point than:
“Please send price for RC rig.”
STOP BUYING A DRILL RIG. START BUYING A DRILLING CAPABILITY.
That's the message.
A drill rig is important.
But it doesn't produce metres by itself.
The compressor matters.
The rods matter.
The hammer matters.
The bits matter.
The cyclone matters.
The hoses matter.
The tooling matters.
The spares matter.
The support fleet matters.
And the people operating all of it definitely matter.
CED's job is to bring those pieces together.
RC DRILLING.
AIR CORE DRILLING.
RIG + AIR + RODS + TOOLING + SAMPLING + SPARES + SUPPORT.
One coordinated package built around the actual exploration programme.
Because the objective isn't to own a drill rig.
The objective is to drill.
Cylinder Exploration Drilling supplies RC and Air Core drilling rigs, compressors, rods, hammers, bits, cyclones, tooling, consumables, spare parts, support equipment, commissioning, personnel and complete exploration drilling packages worldwide.
Planning an RC, Air Core, grade-control or mineral exploration drilling programme?
Send CED the location, expected metres, hole depths and drilling requirements. We'll build the package around the job.
Over to the drilling crews
When setting up a new RC operation, which part of the package gets underestimated most often — the compressor, drill string, sampling system, spares or support equipment?
