Great Panther is a low-cost producer with a very strong leverage to the price of silver. The company operates three mines, including the Tucano Gold Mine in Amapa State, Brazil, and two primary silver mines in Mexico: the Guanajuato Mine Complex and Topia Mine.
The ropes gold mine is the most important historic gold mine in Michigan’s Upper Peninsula. The mine has a great history that dates back to 1881 when gold was discovered at its site near the town of Ishpeming by Julius Ropes, a postmaster, a former druggist and a school board member.
About 250 km southwest of Sydney, the mine operated from 1978 to 1998 under a previous owner until low metal prices and corporate issues stopped production. Heron became the eventual owners. After receiving an A$240M funding package last year, the company is now re-processing the medium-grade tailings, as well as re-developing the underground mine.
