The Porcupine Gold Rush was a gold rush that took place in Northern Ontario starting in 1909 and developing fully by 1911. A combination of the hard rock of the Canadian Shield and the rapid capitalization of mining meant that smaller companies and single-man operations could not effectively mine the area, as opposed to earlier rushes where the gold could be extracted through placer mining techniques. Although a number of prospectors made their fortune, operations in the area are marked largely by the development of larger mining companies, and most people involved in the mining operations were their employees.
The Cobalt silver rush was a silver rush in Ontario, Canada that began in 1903 when huge veins of silver were discovered by workers on the Temiskaming and Northern Ontario Railway (T&NO) near the Mile 103 post. By 1905 a full-scale silver rush was underway, and the town of Cobalt, Ontario sprang up to serve as its hub. By 1908 Cobalt produced 9% of the world's silver, and in 1911 produced 31,507,791 ounces of silver. However, the good ore ran out fairly rapidly, and most of the mines were closed by the 1930s. There were several small revivals over the years, notably in World War II and again in the 1950s, but both petered out and today there is no active mining in the area. In total, the Cobalt area mines produced 460 million ounces of silver.
