Two mineral sites are located in the neighborhood of Sant'Agostino church:
- an occurrence of aragonite, calcite, hydromagnesite, jamborite, pyroaurite, etc. in highly fractured serpentinite, located uphill from the sanctuary towards Santa Barbara Pass;
- An occurrence of datolite, prehnite, analcime, and probable laumontite in altered gabbros, located downhill from the sanctuary towards Coli.

To reach the former locality, cross Coli and continue for three kilometres after the village of Fontana, then turn right at the fork and continue for two kilometres, passing over the sanctuary of Sant' Agostino. The mineral site is at the left, before the curve of the road.
