1. State‑of‑the‑Art Track‑Mounted RC Rig

Ragnarock now operates a powerful track-mounted Reverse Circulation rig, engineered for maximum precision and mobility across rugged terrain. It enables deeper drilling (up to 500 m) while maintaining stable, aligned hole trajectories

2. High-Precision, High Yield Drilling

With RC drilling technology, clients receive clean, uncontaminated core samples efficiently. This allows faster progress and reliable water source planning in both farm and commercial settings .

3. Low Environmental Impact

The rig’s built-in dust collection system and cyclonic sediment extraction keep the drilling site clean and eco-friendly. This means less soil disruption, no toxic runoff, and better compliance with environmental standards .

4. Rugged Mobility for Remote Sites

Mounted on robust tracks, the rig easily navigates soft soil and off-road terrain, making it ideal for rural and remote locations where traditional rigs struggle to access .

5. Efficient Drill Performance

Equipped with a powerful 385 kW Cummins engine, hydraulic rod changer, and adjustable mast, the rig operates with impressive torque and precision up to 500 meters deep, drilling fast without compromising safety or sample quality.

6. Safety-Centric Design

Minimal manual handling of heavy drill rods, remote control options, and automated rod breakers significantly reduce risk to operators. The rig’s design follows modern safety best practices across Zimbabwe’s challenging terrains .

7. Versatility Across Applications

Whether for community water supply, agricultural boreholes, mineral exploration, or deep geotechnical drilling, Ragnarock’s new rig adapts seamlessly to each job type with unmatched speed, depth, and reliability.

Welcome to the newest addition to our fleet! One of the key features of our track-mounted drilling rig is its mobility. Equipped with tracks instead of wheels, this rig can traverse rugged terrains, including muddy, rocky, or uneven surfaces. The design allows it to easily access remote and challenging drilling sites. Being track-based provides a more stable platform, resulting in better hole alignment. Our track-mounted rig can reach depths of up to 250 meters in rugged terrain, while also reducing environmental impact due to its increased manoeuvrability, which leaves a smaller footprint.

Gold RC Drilling  in Shamva

 Reverse Circulation (RC) drilling ideally produces dry rock chips, as large air compressors dry out the rock ahead of the advancing drill. This method is one of the most popular for mineral exploration drilling.

 Reverse Circulation drilling uses rods with inner and outer tubes, allowing drill cuttings to return to the surface inside the rods. The drilling mechanism employs a pneumatic reciprocating piston, known as a hammer, which drives a tungsten-steel drill bit. Reverse circulation is achieved by blowing air down the annulus, creating differential pressure that the cuttings up the inner tube within each rod. This material reaches the deflector box at the top of the drill string, then moves through a sample hose attached to the top of the cyclone.

 Our cyclone is equipped with two sample boxes and a built-in splitter. The drill cuttings travel around the inside of the cyclone until they fall through an opening at the bottom, where they are collected in a sample bag. For each drill hole, there will be a large number of sample bags, each marked to record the location and drilling depth from which the sample was obtained at 1 meter intervals . These sample bags are later taken for analysis to determine the mineral composition of the drilled hole. The analysis results for each individual bag represent the mineral composition at a specific sample point in the drill hole. Geologists can then review the ground analysis and make informed decisions about the value of the overall mineral deposit. Reverse Circulation drilling is one of the more cost-effective options for surface drilling. Generally, RC drilling is slower and more expensive than other methods like RAB but it achieves better sample recovery and has little to no cross contamination. It is also cheaper than Dimond (core sampling ) Drilling.
