Kelly Lake

La modélisation de la réponse de la gravité en trou de forage démontre sa valeur potentielle en exploration.

Kelly Lake is a deep Cu-Ni magmatic deposit located in the Sudbury Mining Camp, Canada.


The Kelly Lake deposit has been well documented by intensive drilling; zone densities have been estimated from drill core and gamma-gamma logging.

Due to the considerable depth of the Kelly Lake deposit, the surface gravity anomaly is negligible.

Using the known density distribution for this deposit the gravity profile for a near-miss hole was modeled.

This model clearly shows that the deposit could be detected from a near-miss borehole.
