LARGE DIAMETER / BULK SAMPLING
MSD provides RC drilling services to exploration companies across northern Canada and the continental United States.
Core and cuttings recovery are NI 43-101 and JORC compliant for mineral exploration reporting. The efficiency of MSD’s light-weight, heli-portable drill rigs allow mobilization to remote, and difficult to access work sites where conditions can be challenging.
MSD can provide ODEX (Overburdne Drilling Excentric) as an option to a mineral exploration drill program. ODEX is a technique that uses casing to line a hole when passing through soil overburden before entering rock. ODEX drilling allows for drilling and casing deep holes simultaneously in most geological formations, as well as in old construction materials such as brick and concrete.
For mineral exploration drilling, MSD employs set ODEX casing at the top of each hole until bedrock is encountered. This reduces caving and helps direct the sample into the center of the drill pipe through the use of a sealed diverter between the casing and the drill rod. Additinally, we prefer to use threaded casing to speed up the process of installing and removing casing, rather than welding and cutting casing for every hole.
MSD’s air rotary drills also serve as geotechnical drills for installing ODEX casing and down hole hammering. MSD carries in stock 4″, 5″, 6″, 8″, 10″ and 12″ ODEX systems. Additional sizes are available on request.
