Exploration works prior to Magna Gold Corp
Prior to Magna's acquisition of the San Francisco operation, the project had undergone multiple exploration works. There are historical drilling records dating from 1996 through 2018, time at which the most recent drilling campaign was carried out. Since then, more than 500,000 meters of drilling have accumulated. The following table shows the drilling campaigns carried out at the San Francisco mining unit.

Exploration Works by Magna Gold Corp
Magna is to conduct project data review and quality of data validation in order to create a new geological model. Once completed, an updated resources estimate will follow. The company will be reviewing metallurgical information and key economic parameters in order to evaluate the potential economics of an open pit gold mine and a heap leach extraction facility.
