Question: Did the Northland Pyrite Mine and Thompson-Lundmark Mine contain more than just gold?

<P0-S0> The Thompson-Lundmark Mine was a gold producer in the periods 1941–1943 and 1947–1949, near Yellowknife, Northwest Territories. <P0-S1>  Gold was discovered here in 1938 by Fred W. Thompson and Roy Lundmark; they staked 46 claims that were incorporated into the mine. <P0-S2>  Underground and shaft work began in 1939. <P0-S3>  The mine processed 133,989 tons of ore to produce 70,339 troy ounces (2188 kg) of gold and 13,782 troy ounces (429 kg) of silver. <P0-S4>  The abandoned site was destroyed by forest fires during 1998. <P0-S5>  A detailed history is available in the link below. <SEP> <P1-S0> Copperfields Mine, originally known as Temagami Mine, is an abandoned copper and silver mine on Temagami Island in Lake Temagami, Ontario, Canada. <P1-S1>  The mine opened in 1955 and comprises both underground and surface workings within a sulfide ore body. <P1-S2>  Situated in Phyllis Township, the mine produced 34,000,000 dollars Canadian with 80 million pounds of copper, 230,028 ounces of silver and 13,271 ounces of gold. <P1-S3>  It was considered to be the largest deposit of nearly pure chalcopyrite ever discovered in Canada. <P1-S4>  A mill was not initially needed because the ore was 28% copper. <P1-S5>  The mine closed in 1972 and is now flooded by water. <P1-S6>  Ruins of the Copperfields mill are present as foundations. <P1-S7>  It is possible to find mineral specimens in the spoil heaps of the old mine, such as chalcopyrite, pyrite, bornite, malachite, dolomite, hessite, merenskyite, millerite, palladium, quartz and others. <P1-S8>  The Lake Temagami Access Road was created to ship ore from the mine site. <SEP> <P2-S0> The Northland Pyrite Mine, also known as James Lake Mine, Rib Lake Mine, Harris Mine or simply Northland Mine, is an abandoned underground mine in Northeastern Ontario, Canada, located on the southwestern shore of James Lake in Best Township of Temagami. <P2-S1>  It was operated by the Northland Mining Company during the early 1900s with the construction of a 91 m shaft and many open-cuts north of the shaft. <P2-S2>  Minerals present at the mine include chalcopyrite, pyrite and pyrrhotite, deposited in Precambrian volcanic rock of the Canadian Shield. <SEP> <P3-S0> The Løkken Mine is and underground pyrite mine located in the municipality of Meldal in Sør-Trøndelag, Norway. <P3-S1>  The mine was operative from 1654 to 1987, from the mining community Løkken Verk. <P3-S2>  It contained the largest deposits of its kind in Norway. <P3-S3>  Between 1654 and 1845, a total of 11,300 tons of copper was produced from the mine. <P3-S4>  From 1904 the mine was run by the company Orkla Grube-Aktiebolag, and until 1987 a total of 24 million tons of pyrite was produced from the mine. <P3-S5>  In addition to sulphur, the pyrite contained about 2% copper, in addition to zinc and traces of silver and gold. <P3-S6>  The products were originally transported to the sea by horse and sledge during winter time. <P3-S7>  From 1908 the ore was transported by the Thamshavn Line, which was the first electrical railway line in Norway. <P3-S8>  The annual production was about 350,000 tons of ore during its final years.
