Core Orientation
Core Orientation has been around since the mid-1800s, a maneuver used to define the geological structure, gain geotechnical information, the determining bedding plane, azimuth and inclination the formation is dipping at.” Because core gives a record of underground geology, good drilling companies have perfected how to maximize recovery, yielding samples that are reliable, sound, and expertly excavated.Geophysical data can only get a driller and geologist team so far. Minerals and rock can fold, dip, or fault. With oriented core data, a more cost-effective and refined approach can be used by using previously cored samples as a guide. Similar to a compass, core orientation points the way and facilitates where to plan and drill the next hole.
Core Orientation is beneficial in determining an orebody reserve’s estimate. It also improves mine planning, geotechnical mine design, and safety issues. This method provides data for effective discovery. It is also used for planning and extraction. Each orebody structure has its own complexities. The Core Orientation process affects estimates of the ore body. The data produced from this process makes core orientation indispensable.After a drill run is completed, and the core samples come up, drillers are trained to work closely with a geologist to mark the core. In this photo, you’ll notice the core orientation markings with the black arrows indicating the downward-facing hole direction.
