Diamond drilling for exploration purposes to obtain core samples of ground and rock, underground (in mines) or surface. Holes drilled range from 100 to 3,000 feet deep. A core sample collects in an inner tube that can be pulled to the surface without pulling the bit. Seismic drilling, when conducted as part of the diamond drilling operation.	Drilling for oil and gas is found under 202-04 – Oil and gas wells. Mining activities are found under 201-02 – Mining, exploration and prospecting. Seismic drilling for exploration purposes is found under 201-02 – Mining, exploration and prospecting.
Water well drilling. Generally, a truck-mounted auger drills wells for water 50 to 500 feet in depth. Once the hole has been drilled, a casing or shaft is placed in the hole to prevent the hole from caving in and contamination. The contractor may install the pumps (surface or submergible).	Drilling done in conjunction with the installation of ground source heating and cooling systems is found under 402-04 – Plumbing, insulating and mechanical. Oil or gas well drilling is found under 202-04 – Oil and gas wells. Drilling piles for foundation work may be found under: 407-06 – Excavation, foundations, installing pools and tanks 407-09 – Piling and underwater construction Drilling concrete can be found under 401-10 – Concrete work. Post hole drilling for wooden fencing can be found under 401-02 – Building construction. Custom post-hole drilling is found under 408-09 – Equipment contracting
The operation of a quarry – an open pit used to mine building stone. Includes cutting the stone into building blocks/bricks/pieces and/or crushing the stone into gravel. May include polishing (e.g. granite). Types of stone in Manitoba are usually Tyndall stone, limestone or granite.	The manufacturing of man-made construction blocks/bricks is found under 314-08 – Manufacturing bricks and blocks. Finishing stone pieces into a variety of usable items is found under: 321-02 – Manufacturing stone and marble products. The operation of a sand or gravel pit is found under 408-06 – Gravel and stone pits.
Harvesting peat moss involves draining a marsh or bog where the peat moss is scraped off, stockpiled then vacuumed to remove any foreign material. Processing the peat includes milting and pulverizing, then adding moisture before being bailed and packaged. Soil additives may be added to the processing to produce potting soil as a by-product.	The production of any other kind of fertilizer or potting soil is found under 316-16 – Manufacturing fertilizer and potting soil.
