Mines of the Cobalt-Gowganda Area

This listing of mines of the Cobalt-Gowganda area is a distillation of the mines listed in “Silver Cobalt Calcite Veins of Ontario, Ontario Department of Mines, by A.O. Sergiades, 1968. Changes that are known have been added, along with notes of particular interest to mineral collectors. The Lat/Long coordinates have been cross–referenced with current coordinates in the Government database in a best effort to be accurate. If you’d like to get a better visual idea of where many of these mines were, please visit the “Antique Map of the Cobalt Mining Camp” map located in the “Articles” section of this website.

I think that there are certainly errors in this material but, for the most part, there is good information on all of the bigger specimen producers and obscure mines.

Please note that most of these old mines are on private property and that permission needs to be obtained to visit any of them.

Alexandra Silver Mining Company

The Alexandra Silver mine was started in 1906 and became the Canadian Gold and Silver Mining Company in 1913. After two years of operation it was leased to various individuals, until 1962 when Silverfields Mining Corporation began to work it.

During the 1970s and 1980s, Teck Corporation purchased the Alexandra Property and operated it as the Silverfields mine. Teck mined and milled ore from other claims in the Cobalt Camp and operated them all as the Silverfields mine. The main Silverfields mine shaft and mill were near Cart Lake and served as a main source of mill feed. The Silverfields mill, however, also processed ore from dumps, small underground operations, pillar mining operations and as a custom milling operation, until 1983.

Beaver Consolidated Mines Limited

The Beaver has long been a source of excellent high grade silver/cobalt specimens as well as leaf silver. In the late 1990s, cobalt ore was recovered from both the old Beaver and Timiskaming mines simultaneously from a shaft on the Beaver mine property and so newer dumps on the property are composed of a mix of material from both claims. Collectors may, thus, encounter specimens from the Beaver-Timiskaming mine.

Mines of the Cobalt-Gowganda Area

When I (DKJ) attended the Haileybury School of Mines, I visited the underground workings of the Coniagas (Cobalt-Nickel-Silver-Arsenic) mine a couple of times to learn how to do geological mapping underground. I recall that the mine manager showed us big chunks of high-grade silver consisting of masses of black, heavy silver arsenide and sulfide mineralization that they were recovering from “pillar-robbing” extraction work.

This claim was operated by W. Trethewey for two years before it was acquired by Coniagas Mines Limited It was bought and sold by a number of companies over the years.

The Drummond mine was owned by Henry Drummond, a famous Canadian poet. He immigrated from Ireland, attended McGill University and became a medical doctor.  He became famous writing poems about the French Canadian Habitant, the rural people of Quebec. He learned about the silver strikes at Long Lake from an assayer at McGill University and headed to Cobalt. He staked a claim just north of Kerr Lake, and operated and managed the Drummond mine until his death in April of 1907. The Drummond Cairn was originally the chimney from his home, beside the mine. It was designated an historical place in the 1930s and more recently was moved into Cobalt from the mine site, near Kerr Lake.

Nipissing Mines LimitedMost mines of the Cobalt area were each located on a single claim or portion of a claim. The Nipissing mine property however was originally staked as four claims, on some of the richest ground in the Cobalt Camp. This explains the extensive workings and large mill site of “the Big Nip”. The many mine dumps have been the source of some nice high grade silver and silver leaf over the years. As well, because of the concentration of veins on the property, very good “Glacial Float” has been located by collectors with metal detectors. These claims were eventually all acquired by Agnico mines and operated along with other claims from the 1960s until the 1980s.

The O’Brien mine yielded some amazing high grade in its heyday. Some of this material escaped the miners and can still be found to this day on mine dumps. As well, the O’Brien had zones that produced good crystals of acanthite pseudomorphs after argentite, proustite and other secondary silver minerals. If collectors encounter well-crystallized specimens of such minerals from this (or any others) mine, they are no doubt very old specimens from the actual mining operations.

Interestingly this claim was put aside by the government of Ontario to be mined by a government-controlled company “for the people” something unusual for the time. The mine was opened but operated for only a short time before the ore ran out. It was a money losing venture. The government turned it over to a private company who also failed to make it go.

Also popularly referred to as the Langis mine, after the Langis Silver and Cobalt Mining Company, a company which operated it for a while during the 1960s. The Langis has been the source of some of the best dendritic silver, high-grade ore. Specimens often consist of chunks of ore, sawn to reveal intricate “herringbone” patterns of silver crystals, usually coated with arsenide minerals in carbonate vein material. Sometimes the carbonates can be leached away with acid to reveal excellent herringbone crystal structures. The Langis mine is located on an isolated patch of Cobalt sediments and Nipissing diabase about 12 miles north of Cobalt, at the north end of Lake Temiskaming, near New Liskeard.

The Moose Horn mine was not a prolific silver producer. Only a few tons of silver ore, rich in nickeline were ever shipped. However, the Moose Horn mine was the source of Temiskamite, Ni11As8, which was proposed as a new mineral and was, in fact, a new mineral. Unfortunately, German scientists had characterized maucherite just prior to the characterization of Temiskamite and thus the name maucherite took priority. Temiskamite was subsequently discredited.

The Capitol mine has been a favorite collecting locality for collectors with metal detectors and has produced many fine specimens of dendritic silver ore over the years. Much bulldozer work was done on the dumps and grounds of this property in 2012, which  revealed large amounts of high-grade silver ore, much of which has been recovered by collectors with metal detectors.

This mine, also known as the Rustex mine and Rusty Lake mine, has produced superb specimens of skutterudite. The skutterudite occurs as crystals in calcite veins, with silver and other arsenides. The calcite can be removed with acid to reveal clusters of sharp, lustrous skutterudite with crystals to 0.5 inches in size.

The “Woods Vein” of this rich silver producer was also a prolific specimen producer. Most of the mines in the Cobalt area did not contain many open vugs where proustite, wire silver and other rare silver minerals could form. According to Sergiades, 1968, pg. 428, “Pre-glacial weathering on part of the Woods vein extends to 480’ depth; ore deposition in consequence is partly secondary and the vein vuggy.” The collection of the Royal Ontario Museum has excellent specimens of wire silver from the Keeley and Frontier mine as well as superb proustite specimens with well formed crystals to 0.75 inches.

This was a rich mine and superb examples of high-grade ore have been found in the waste dumps with metal detectors.

Note about Silver Centre: When the South Lorrain Silver Mining area was booming starting in 1907, a town called Silver Centre was established. It was a proper town, with a well laid out town site and with great hopes for the future. Unfortunately it did not last. It is considered the area’s “ghost town” and remnants of Silver Centre may still be encountered in what is now wilderness, again. It is mentioned here since collectors may very well run into this name on labels or in writings on the Cobalt area. Interestingly, there is still a road sign in North Cobalt that points people in the right direction and distance for Silver Centre.
