Jan 27, 2017 (A Wilson) - Rocks present are rusty syenite gneiss, crystalline serpentine limestone and pegmatite. This deposit was opened as a phosphate prospect about 1900. Apatite occurs as light green transparent crystals and granular masses in coarsely cleavable pink to white calcite which fluoresces bright pink under "short" ultraviolet rays and reddish pink under the "long" rays. Black mica and colourless crystals of orthoclase also occur in the calcite. The pegmatite contains crystals of dark green amphibole, pink feldspar, biotite, titanite and pyrite. Crystalline limestone associated with the deposit contains orange chondrodite, light green and blue apatite, mica, colourless to smoky clinoamphibole, colourless to light green clinopyroxene and serpentine. These minerals occur in the adit area and in the nearby trench. Thorite, thorianite and uranophane occur as irregular grains and aggregates in calcite exposed by a trench on the ridge that parallels Gibson Road. Colourless, white and light grey clinoamphibole is abundant as coarsely bladed aggregates. Smoky quartz, light green clinopyroxene, green apatite, pyrite and white to grey and tan-coloured talc also occur in the calcite.

Jan 27, 2017 (A Wilson) - Small books of amber mica and apatite occur in coarse white calcite vein material. A. Gibson reported that books as much as 16 inches in diameter were found in the bottom of the pit and that shipments were made. Old workings for mica occur in the northwest corner of lot 16, concession X, Monmouth township, northwest of McCue Lake. The main working is a curved trench 95 feet long, 20 feet wide, and from 5 to 10 feet, deep with a pit 25 feet in diameter and 15 feet deep. Several small pits occur to the northwest. The work was carried out about 1900, and the trench and pits are now overgrown.
