The Jose Panganiban-Paracale mineral district is  characterized by andesite and sedimentary sequences probably if Eocene age intruded by Paracale granodiorite during the Miocene Orogeny.

The granodiorite brought about the gold mineralization localized around the periphery of this intrusive surrounded by gneiss, schist, peridotite and other metamorphic derivations. The granodiorite intrusive possibly influences the northwest trend of the primary grain of the district. 

Some 2.5 kms south of the gold zone is the 25 km. Long arcuate iron belt localized within the contact of the sedimentary rocks and the Larap volcanics. Such iron belt is theorized as a contact metamorphic type of deposit. The belt is a southeast to east trending zone starting from Larap region going southeast towards the direction of the foot of Mt. Bagacay at Labo, Camarines Norte.

South of the iron belt is a base metal zone of mineralization with some gold 7 silver association of potential commercial importance. The base metal mineralization is localized in the andesite and sedimentary rock units.

Iron ore minerals within the mineralized district consist of: Pyrite, Chalcopyrite, Magnetite and Hematite.

Occurrences of base metals such as lead and zinc could also be encountered in the ore as sulfide minerals.
