Boart Longyear

Boart Longyear supports drill programs that have to do more than reach depth. When the job has to answer geology, water, access, and production at the same time, we build the plan around the formation and the result the project needs. We support mineral exploration drilling, and we also work on water services and production drilling for mining and resource operations worldwide. The point is not simply that we have a broad menu of methods. The point is that we can match the method to the ground, the sample target, and the operational constraints instead of forcing the site to adapt to a fixed setup. For the buyer, that means fewer compromises when the priority is clean data, steady progress, and equipment that can hold up in demanding field conditions.

Surface coring is practical when the first read on the formation has to be as clean as possible. Underground coring serves programs that need control and sample recovery below ground, where access and structure can change the plan quickly. Those methods help a team verify layers, compare intervals, and move into the next phase with better evidence instead of guesswork. They also reduce the risk of building later decisions on incomplete ground conditions. In a mining or resource program, that shows up because a poor early read can affect hole placement, sampling confidence, and the timing of later work. Our approach is to keep the drilling method aligned with the information the project is trying to protect.

When the hole has to move through difficult ground, the method choice can matter as much as the rig itself. Reverse circulation drilling and rotary drilling serve different formation and production needs, and directional drilling adds control when the path has to stay planned around target zones, access limits, or site layout. We use those options to balance speed, accuracy, and reach against the real conditions in front of us. That can make the difference between a program that stays on line and one that loses time to rework or avoidable deviation. If the project is working through changing rock, constrained access, or a target that cannot tolerate drift, we can choose the method that best fits the hole.

Sonic drilling gives us another way to handle mixed ground or constrained sites where a standard approach may not protect the sample or the schedule. It is practical when the job has to adapt to changing overburden and still preserve the project’s sense of direction. Water work sits in the same operating picture. We provide water supply drilling when a site needs a dependable source, dewatering when groundwater has to be controlled, and pump services when flow has to stay stable enough for the next phase of work. Those services help keep field teams moving through wet ground and changing subsurface conditions, and they give a project a more coordinated way to handle the water side of the job instead of splitting that responsibility across multiple vendors.

The rig side shows up because a good plan still depends on machines and tooling that can support it. Our drill rigs and performance tooling are built for long life and high performance, and the technology behind them is intended to keep productivity up while supporting the safety features the job demands. We also work with drilling products that help keep productivity promises realistic in the field. That shows up on programs where moving the rig package, keeping the hole productive, and protecting the job site all have to happen at once. A well-matched rig and tooling setup can reduce avoidable downtime, cut handoffs, and keep the crew focused on the next metre instead of the last problem. For a buyer, the practical benefit is clearer control over schedule and a better fit between the drilling package and the geology.

We have been doing this since 1890, so our work is shaped by continuity as much as by individual projects. Drill programs change as the formation changes, but the need for dependable equipment, usable data, and steady progress does not. That is why we keep the focus on the relationship between method, tooling, water control, and the result the site needs. If your program needs a mineral exploration drilling contractor, a water-services partner, or production drilling support that can be matched to the ground instead of forced onto it, we can help choose the setup that fits the hole, the timeline, and the result you need.
