Jun 13, 2023 (Therese Pettigrew) - From Mulligan (1968 p. 86): "This locality apparently is that of the reported radioactive occurrences on lots 15 and 17, cone. XII, about a mile northwest of Tory Hill. According to Satterly hornblende-syenite pegmatites are cut by calcite-apatite veins ....A variety of rare elements including beryllium were reported by the owners." Four pits opened prior to 1943 exposed pink and green pegmatite and hornblende syenite pegmatite cut by a 4- to 5-foot hornblende-calcite-apatite-feldspar vein. Accessory minerals include magnetite, sphene, and scapolite. Uraninite and uranothorite were reported (Gordon et al., 1981).
