What are the main types of errors that affect the accuracy of the collect data in the exploration?

Hi @AbuelgassimAboubakar

That is a fantastic question, and this is a very broad topic with potentially many answers.

To begin with, the fundamental data collected during exploration could be:

• mapping data - lithological contact boundaries
• structural measurements
• sampling locations
• collar, survey and geology tables during exploration drilling

With mapping data, errors could include:

• incorrect location information of mapped lines
• incorrect georeferencing of the base map
• incorrect direction data by the geologist (e.g. the geologist indicates a unit is dipping east when it is actually dipping west)

Structural measurements may be unreliable if:

• Again, dip, strike or dip directions, or Alpha and Beta measurements are mixed up or read incorrectly on the measuring device
• The measurements are not georeferenced properly and appear in the wrong XYZ/location

Sampling locations can also have their locations recorded incorrectly.

Drilling data is subject to the same opportunity for error, predominantly location error of collars and surveys (incorrect XYZ), but also data entry error by the logging geologist. Additionally, there are analytical errors that the laboratory may experience that would impact the reliablity of exploration projects.

Hope some of this helps,
