Probably a carbonatite intrusion into biotite-amphibolites and syenitized gneisses. Famous for its betafite crystals.
"Silver Crater Mines, Limited, was incorporated in February 1951, with an
authorized capitalization of 3,000,000 shares of ftl par value, of which 2,543,215 have been issued. The head office is at 696 Yonge Street, Toronto. The mine address is Cobalt.
The company owns the Silver Banner and Ophir properties and has a lease
on the Mensilvo property, all in Coleman township, district of Timiskaming.
It also holds claims in Faraday Township, Hastings County.
The Basin property of Silver Crater Mines, Limited, comprises lot 31, concession XV, Faraday Township, Hastings County. The property was acquired in 1953. It is about 8 miles west of Bancroft and is accessible from the Monck road by a truck road 2 miles long. Silver Crater Mines, Limited, is a wholly-owned subsidiary of International Cobalt and Silver Mining Company, Limited.
In 1953-55 the company carried out exploration on a carbonate body containing crystals of betafite, a multiple oxide of niobium, titanium, and uranium.
Although the occurrence is very similar to pyrochlore-bearing carbonate bodies of igneous origin, the Silver Crater body is believed to be hydrothermal.
In 1925 the north end of the carbonate body was worked for black mica by
S. Orser and D. J. Wilson, and from 1947 to 1949 the property was operated by Bancroft Mica and Stone Products Mining Syndicate, Limited, producing scrap and trimmed mica. This production all came from an open-pit, which, in 1949, was 30 feet in diameter with a 65-foot wall against the slope of the hill, and a 12-foot wall on the outer side.
Silver Crater Mines, Limited, commenced operations in 1953 and explored the radioactive part of the carbonate body to the south of the old mica pit by a number of trenches and six shallow, X-ray drill-holes. The work was continued in 1954 by bulldozing overburden and weathered rock from the top of the carbonate body and by diamond-drilling. By the end of 1954, 14 inclined holes and 9 vertical holes, totalling 4,274 feet, had been drilled.
Drilling was continued in 1955, 11 vertical holes being completed for a total footage of 1,339 feet. The carbonate body was also explored by an adit, the underground development amounting to 435 feet of drifting and crosscutting and 94 feet of raising. The property was inactive in the latter half of 1955.
The property lies in a zone, about 3/4 mile wide, between a large area of
granite and hybrid granite gneiss to the north and an area of marble and associated metasediments to the south. This zone consists mainly of syenite, and syenite gneiss, to a lesser extent nepheline gneiss, and contains small areas of hornblende-plagioclase gneiss." (ARV65)
