Point Location Description: Pb symbol NE of Long Point on map 2054
Location Method: Conversion from MDI
Access Description: The occurrence is located approximately 5.0 km south of Lyndhurst and 0.75 km northeast of Long Point. It is accessible on foot from a gravel road which passes through Long Point and joins to a paved road at Lyndhurst.
1854: A shaft 50 feet deep was excavated on lot 3, conc. VII. Pre-1863: An unspecified number of shafts were opened on lot 2, conc. VII by unknown operators. One shaft was excavated on lot 4, concession VIII by Mr. Foley and company. 1875: Several shafts were opened on lots 3, 4 and 5, conc. VII and at least 1500 feet of drifting was completed. A small amount of lead was produced from a smelting furnace. Pre 1927: A total of 15 shafts and pits were reported on the property. (OFR 5548, p137).
Province: Grenville

Geological Age: Mesoproterozoic
Dec 07, 2005 (C Papertzian) - The mineralization occurs within a system of calcite veins in a marble host rock. The major vein has an average width of 2 feet and extends for 0.25 miles. A second mineralized vein 0.5 to 1.0 feet wide branches into 4 parallel veins over a zone 1000 feet wide (Logan 1863, p.688). The rocks in the region are comprised of thick folded sequences of interlayered marble, granite gneiss and quartzo-feldspathic and pelitic metasedimetary rocks intruded by the Lindhurst Granite pluton. In the area of the showings, the marbles trend northeast and are steeply dipping. Wynne Edwards, 1967, p123-124 describes the geology as follows: Galena is the only abundant sulphide, and occurs with small amounts of chalcopyrite, celestite and barite, in crystalline masses up to an inch in diameter, scattered through coarsely crystalline calcite gangue.

Geologist: C Papertzian
Notes: The property was visited on October 1st, 2004 along with the Mine Hazards Co-ordinator. The largest opening was a shaft/adit that measured 40 feet long, 20 feet wide and approximately 10 feet deep. There was a very small adit that led off to the northeast at the end of this trench for approximately 10 feet. The opening had a strike of 294 degrees. Just to the north of this opening another occurred which was approximately 7 feet long by 3 feet wide. There were also numerous pits off to the northeast.
