Point Location Description: Dot symbol Mi,Ap just east of Eel Bay on Sydenham Lake.
Location Method: Conversion from MDI
Access Description: From Kingston, drive north on highway # 38 to a 5 way intersection in Harrowsmith. Turn east on county road # 5. Follow this through Sydenham and on to Spaffordton. Then turn north on the Wilmer road to the second side road, called the Hogan Road. Turn west on the Hogan road. Continue on this road past the abandoned rail way tracks. Continue on until just before the road narrows. At this point there is a gate on the north side of the road. Park the vehicle at this point as the gate is usually chained shut. Follow this road for approximately 15 to 20 minutes to the mine site. The surface rights are privately owned and the owner should be advised before walking into the mine.
The deposit was first located in 1882, and was worked for several years for phosphate by Messers. Smith and Lacey, of Sydenham who subsequently continued mining for mica. The amount of phosphate extracted was probably less than 200 tons. Acquired by the General Electric Company in 1894, and was worked under lease by Webster and Company, and Mr. J.W. Trousdale of Sydenham. The General Electric Company then operated under the name of the Loughborough Mining Company. Production was carried out in 1900, 1902-1927 and 1947. This property was mined almost continuously from 1880 to about 1930. It reopened for a short time during world war 2.

Dec 07, 2005 (C Papertzian) - Phlogopite mica occurred in veins and pods in metamorphic pyroxenite. The main vein strikes NW-SE and dips vertically. In width the lead varies from a few inches to 25 feet, being, in some places a solid mass of large mica crystals. One of the largest crystals measured over 9 feet in diameter. The country rock is gneiss and mica schist. (From MRC 8, 1968).

Notes: This was the largest phlogopite mica mine in Canada and produced intermittently from 1880 to 1947. Total production was 5,781 tons valued at $827,756. Spence (1929, p.69) describes the workings as follows: 'The deposit was originally worked from a shaft, 185 feet deep, with drifts run at 22-foot intervals along the vein. The longest drift was on the fourth level, this being carried 150 feet to the southeast and 65 feet to the northwest, a total of 215 feet. A crosscut was also driven 60 feet to the southwest on this level, to pick up a parallel vein which was followed by drifts for a distance of 160 feet to the southeast. From the second level a crosscut to the northeast encountered a third vein at 55 feet, and this was followed for 80 feet to the southeast. Later, it was decided to glory-hole the workings, and a large open pit, 60 by 70 feet, was sunk upon the main and northeast parallel veins. Most of the work in recent years has been carried out from this excavation, and has consisted in drawing the pillars and caving the ground between the old stopes, the mica being recovered druing mucking operations. In 1923, a new shaft was sunk south of the main shaft to a depth of 180 feet.' This property was visited on January 28th, 2000. At that time the two shafts mentioned above were evident. The pit was water filled and measured 100 by 200 feet long. Two other large pits and one smaller one were also noted. At the bottom of one of the pits an adit was noted. All of the above were located on lot 10 con 7. On March 24th, 2000 an inspection was carried out on lot 11, con. 7 with a contractor who was to rehabilitate the property. Two additional pits, a shaft and an adit were noted. A number of shallow pits were also evident. The largest of the pits on lot 11, measured 50 by 40 feet by 25 feet deep. On April 26th another inspection was carried out. All of the above pits and addits had been either filled, sloped or blocked. The 2 shafts were back filled.

Notes: When the property was visited on Sept. 16th, 2001 there had been some subsidence off of the north end of the main pit. This occurred on one of the smaller pits, not the one with the adit in the bottom of it. The hole is round, approximately 5 feet in diameter. It drops down at least 5 feet and then carries on at a bearing of approximately 240 degrees. The UTM's for this are 377076E and 4921944N. Also another shaft was located that measured 15' by 15' with an indeterminate depth. There were two pipes protruding from it, one a couple of inches in diameter and the other approximately 6 inches in diameter. The surface is covered with debris and it is located 25 feet from the travelled portion of the roadway. The location for this shaft is 377160E and 4921843N. The property was visited again on July 17th, 2002 to check on the subsidence that was noted the year before, (September 16th, 2001). The collapse feature now measured 10 feet square and was approximately 8 feet deep in the centre. This feature was water filled until recently. It is located some 60 feet north of the main pit on a side hill. There was no obvious hole extending below the 8 foot level.
