By 1903, Burke Canyon was the most developed mining region in the Coeur d'Alene Mountains and was home to seven dividend-paying mines: the Gem of the Mountains, Frisco, Mammoth, Standard, Hecla, Tiger-Poorman and Hercules mines. Other mines soon began production throughout the Coeur d'Alene mining district, including the Bunker Hill Mine (1886), Star-Morning Mine (1887), Sunshine Mine (1890), Galena Mine (1922) and Lucky Friday Mine (1942).
