With the emerging need in Atlantic Canada for cost-effective exploration, our Tonka rig has been designed to mobilize rapidly and service areas including Shallow Core Drilling (400M and below) RC Drilling (70m and below), and Percussion assisted coring. 

​

Shallow Reverse Circulation Programs, with core tail ability, to quickly delineate broad shallow areas of interest, while staying within budget.

We are adept in fluid control, re-using fluids, and operating sumpless filtering water to be returned to the environment when drilling is complete.   

Under the Nova Scotia Environment Act, groundwater withdrawal in excess of 23000 liters per day requires a “water approval”. Based on this rate, a typical drilling operation conservatively can use only 30 L/min for a period of 12.75 hours per day. Our proprietary Re-Circulation system allows for a recycle rate that lowers average water consumption to 460 liters per day based on ideal ground conditions.   

By recycling, we are able to operate a 24-hour cycle and obtain a social license from NS Environment within reasonable cost parameters.

     The “Tonka” is designed for very low ground impact and very limited pad size. Our 400m drill has a ground pressure of only 3.2 PSI, reducing ruts and water conduits that would normally allow unplanned water infiltration of the regional watershed.
