Drilling Program – Exploration

Benefits

Compared to diamond core drilling, RC drilling with inherently faster penetration rates provides several benefits:

1. Direct drilling cost reductions in the range of 25% to 40%.
2. Faster completion of drill programs with quicker delivery of results.
3. Reduced man-hours at the drill with decreased exposure to potential accidents.
4. Indirect cost reductions gained from a simplified sampling process.
5. Requires less water than diamond drilling.

When setting up or buying a rig to commence exploration RC drilling there are a lot of factors to consider. Initial costs are high so you need to get it right the first time. Talking to peers in the industry plus rig and consumable manufacturers is a great way to get firsthand experience so that costly mistakes can be avoided. Harley Hollier from Harlsan’s highlights the importance of paying careful attention to initial equipment purchases.

Choices like the type, configuration and setup of a rig has downstream affects on production rates, downtime, profitability and operator safety.

Support Equipment

Exploration drilling requires support equipment. This can vary depending on the amount and depth of holes to be drilled as well as the remoteness of the location. Drilling companies will typically be set up with caravans, satellite communications, lighting towers, auxiliary compressors (with boosters) and support trucks carrying water, fuel, spare equipment & drilling consumables.
