Capsule

Work History

Coal was first noted here in 1887 by G.M. Dawson and first staked as coal lease 214 in Mar/98 by W.T. Edmonds. Restaked as leases 256 and 258 in Nov/99 by J. Cameron and C.E. Miller, who mined several hundred tonnes near surface by 1904. George J. Milton acquired the property in 1905 and formed the Five Fingers Coal CL, which attempted unsuccessfully to diamond drill and then drove two declines (a total of 345 m of development) by 1907. Only a few hundred tonnes were mined and the mine was abandoned in 1908 in favour of the seams at the Tantalus Mine.
The original leases were acquired by Yukon Coal CL and transferred in 1966 to Anvil Mg Corp. L. The surrounding area was acquired in Sep/70 as Coal Exploration Licence 16 by Teslin EL, which performed mapping, drilled one hole (57.3 m) about 1220 m south of the mine in 1971, and staked a coal lease in Nov/73 (2964). The original leases were transferred in 1975 to Cyprus Anvil Mg Corp, which explored with mapping in 1977.

Capsule Geology

Two seams 1.1 and and 1.4 m wide and separated by 7.6 m of rock strike north and dip 16°. The coal occurs within the Lower Jurassic Laberge Formation. A sample analysed by the Department of Mines in 1908 returned 5.29% water, 36.14% volatiles, 40.12% fixed carbon and 18.45% ash, and reportedly produced an excellent, firm, coherent coke. Gross calorific value was reported as 12 100-13 600 G.BTU.
A surface sample taken by Teslin EL from the 1.1 m seam in 1970 assayed 8.4% water, 16.7% ash, 32.8% volatiles, 42.1% fixed carbon and 0.2% sulphur. The coal was found to be non-coking and to have a High Volatile C rank with a dry calorific value of 10 740 BTU/lb.
