Dec 07, 2005 (B Nelson) - The general geology consists of granitic rocks of the Terrace Bay batholith, chiefly composed of hornblende granodiorite. The granitic rocks are intruded by numerous mafic dikes. Molybdenite and chalcopyrite are found in a 109 cm quartz vein in a hornblende granite near the mouth of the Aguasabon River. The occurrence is described by Scott (1977) as: Chalcopyrite and molybdenite occur in narrow (7-13 cm), 61 m long quartz veins cutting a severely deformed grey to pink, medium grained, hornblende quartz syenite. The outcrop area is cut by at least two fault zones of moderate proportions. One strikes approximately 125 degrees and the above mentioned barite fluorite vein occurs in it. The second zone strikes north. Fault displacement on the first is not known. Displacement along the second fault is in the order of feet. The quartz veins and a small diabase dyke are offset by this amount. No mineralization was seen in the host rock. The quartz veins strike southwest and dip to the north. Deformation of the syenite is manifested by the kneaded appearance of the rock, the drag folding as evidence by the foliation planes and numerous small faults and offsets that give the outcrop a blocky appearance. Rock in the fault place property has been completely floured and hematized in places.

Dec 07, 2005 (B Nelson) - Scott (1977) reports the following assays: Material was collected every 15' along the largest vein for a distance of 175' and this constituted the sample sent for assay. Assay results are: Mo: 0.30%, Cu: 0.64%, Au: 0.01 oz./ton, Ag: trace.
