1. Cart Lake Marker
In front of you is what remains of Cart Lake. Silverfields Mining Corp. Ltd. from 1965 to 1983 operated a mill at the former Savage mine site a short distance SE of Cart Lake and disposed of their mill tailings into the lake, filling a good portion of it. It is estimated that the lake currently contains about 1.2 million tons of tailings. Tailings is the term for finely ground up rock that has most of the minerals of value removed. In the distance can be seen the head frame of the Provincial #2 shaft. Silver was discovered there in 1906 and in 1908 a 70-foot-deep shaft was sunk by the province of Ontario, the first and only mine owned and operated by the province. The mine was privatized in 1909 when it was sold to the Cobalt Provincial Mining Company Ltd. However, a headframe was not constructed until 1922 when serious development work was started. The mine was operated intermittently by various companies and individuals until 1968 and produced a total of approximately 300,000 ounces of silver. The picture shown was taken before the Provincial #2 headframe was built and shows the Seneca Superior #1 mine. Veins of silver

Excerpt: This lookout provides a view of a tailings pond that was once Cart Lake. The tailings are mostly from the Silverfields Mill and the Summit Mine which used to be on the Silverfields Road, across the lake. This mill and shaft were operated by Teck Corporation from 1968 to 1983. The Summit shaft was originally part of the Savage claim and owned by the McKinley Darragh Savage Company. Ore from(Submitted on July 14, 2026, by Cosmos Mariner of Cape Canaveral, Florida.)this shaft was shipped to the McKinley Darragh Mill (Site #3) via aerial tramway from 1907 to 1928.
3. Marker detail: Plan of Mine Workings Under Cart LakeLooking to the southwest you will see a rusty headframe on the south shore of Cart Lake. This property is the Provincial #2 shaft and was originally owned and operated by the Ontario government from 1906 to 1909. At this point the government recognized its limited expertise in mining and sold the property to the Cobalt Provincial Mining Company, and reaped the benefits of royalties on production that continued to 1924. The Provincial #2 Shaft reached a depth of 350 feet and produced 287,000 ounces of silver, 54,000 pounds of cobalt and 2,800 pounds of nickel.
