core drilling rig
In 2015 the Company purchased a Termite Hydraulic Core Drill Rig manufactured by Coeur Product of Idaho. From surface, it is capable of drilling to a depth of 100 meters (300 feet) and has a total weight of only 160 kg (350 pounds) that can be transported on the back of a pick-up truck. It is fully hydraulic and has a straight forward, clean design that demands few spare parts. The environmental impact of a lightweight portable drill such as this will be minimal.
The Company also purchased a complete supply of drill rods and spare parts, meaning the future cost of drilling to 300 feet is largely labour and drill bits. Nothing precludes the Company from hiring drilling contractors for deeper drill holes or difficult conditions. The total cost pf the drill, rods and parts was about US $100,000.

The Manufacturer's Description and Specifications are reprinted below from the Coeur Products website:
Designed by Swedish engineers, the Termite Core Drill offers lightweight, modular hydraulically powered solutions for short-hole exploration, definition and grout hole drilling. The Termite Core Drill has a straight forward, clean design that demands few spare parts, making it the most reliable core drill of its kind on the market.
The Termite Hydraulic Core Drill is supplied by state-of-the-art hydraulic components. Equipped with a reliable rotation unit that is driven by a high-tech belt drive, The Termite Core Drill offers the best solution for consistent drilling and accuracy. Our drill is an optimal choice for hole depths up to 100 meters (300 feet).
Not limited to the mining industry, the Termite Core Drill is also designed for construction core drilling purposes with large and small thin-wall diamond bits, as well as for use in the dimensional stone industry for precision drilling of wire cutting holes, and to check on the quarry's material quality.
The total weight of the Termite Core Drill and control panel is only 160 kg (350 lbs.), making it easy to maneuver to and from any site.
Advantages of choosing the Termite:
- Few spare parts
- Simple design for quick maintenance (no special tools or technicians are needed to repair)
- Ease of operation (avoid expensive contractors: do the core drilling yourself!)
The Termite Hydraulic Core Drill can be powered with:
- Tractor PTO
- Bobcat or similar skid steer machines by utilizing their on board hydraulic syststrong
- Diesel or gas power unit
- Electric power unit
The drill frame is constructed out of two hydraulic feed cylinders and two square tubes (1). These are connected at both ends by the connection plates. The front connection plate is also designed to hold the front rod puller (5) and the twomounting screws (6). The mounting tube(7) for the back support leg is located on the rear connection plate.
The drive spindle (4) and hydraulic motor(3) are mounted on the carrier plate that swings out to let rods or core barrels in or out of the hole without having to pass through the chuck. Also on the back end of this carrier plate is a mounting for the rear rod puller (9). The power to thespindle from the hydraulic motor is transmitted via belt drive — a very effective, smooth, low maintenance, and quiet power transmission syststrong.
The drill is operated from a separate control panel (2). The control panel can be separated from the drill by disconnecting it at the bulkhead (10). A separate small hydraulic pump is mounted on the back end of the rotation motor. This unit supplies the hydraulics needed for the drill feed. The feed speed is regulated at the exit of the cylinders. Because of this configuration, feed pressure and feed speed are unaffected by the prevailing syststrong pressure. Therefore, the speed will not change when drilling a void or into an opening.
Two removable wheels (8) are mounted on the bottom of the frame for easy transportation. A support (11) for rod wrenches is located on the carrier; this protects the piston rods when breaking rod connections with wrenches.

Drill feed will work only when the spindle rotates. When setting the feed pressure, knob #8 must be fully closed. The desired maximum feed pressure can then be adjusted with knob #9. 100 bar pressure equals approximately 2200 lbs. of feed force. With knob #8, the desired feed speed can now be adjusted. The pressure reading on Gauge #6 will change while drilling, depending on the feed speed setting on Knob #8. When the pressure on Gauge #6 shows zero while drilling, at that time the feed is working at the full preset pressure.
