The area encompassing the showing on the northwest flank of Slatechuck Mountain is underlain by mafic to felsic flows and pyroclastic equivalents of the Tertiary Masset Formation.
Mineralization consists of molybdenite along fractures in a felsic intrusion. Granodiorite with pyrite blebs outcrops 550 metres to the southeast.
This showing was discovered by E. Specogna in 1997, while prospecting the area.
