Warning! Danger! Stay Out! Stay Alive!
This is a photograph that I took of a warning posted at the entrance to the shaft of the abandoned gold mine at the Goldfield ghost town located outside of the city of Mesa. The mine, itself, is over 1,000 feet deep with seven different levels. The bottom six were permanently flooded in the 1920's when an aquifer was struck at the bottom level. A rich gold deposit was discovered at this place in 1893 and was a productive mine until 1897 when torrential rains caused the mine to flood. In the 1920's, a former mayor of Phoenix, Arizona purchased the land and the rights to the mine, had the water pumped out, and made a sizable profit until the aquifer was struck. During the 1893-1897 period, the population of Goldfield was greater than Phoenix. The production of gold during this four year period, as measured by today's standards, was over 90 million dollars.

Production plant at Sepon copper mine, Savannakhet, Laos
The Sepon copper mine is situated 40 km north of the town of Sepon, in Savannakhet province, south-central Laos. Copper was discovered at Sepon shortly after the discovery of gold. Feasibility studies into the development of the copper project were undertaken in 2002 and construction began in 2003.The operation was commissioned in 2005, with the first copper cathodes produced in March that year. The Sepon copper mine is situated at the same site as the gold operation, and the copper processing plant is located immediately adjacent to the gold plant.

Origin and consumption of mercury in small-scale gold mining [An article from: Journal of Cleaner Production]

Mercury (Hg) is used by small-scale gold miners in more than 50 developing countries, where the accompanied releases affect human health and the environment. The objectives of this paper are to summarize present use of Hg in artisanal and small-scale mining (ASM) worldwide, reveal the origin of part of the Hg used by the gold miners, and propose appropriate actions to reduce the resulting Hg emissions. Significant releases of mercury are associated with inefficient amalgamation techniques. Releases are estimated to range from 800 to 1000tonne/annum. Of this total, approximately 200-250tonne of Hg are released in China, 100-150tonne in Indonesia, and 10-30tonne each in Bolivia, Brazil, Colombia, Peru, Philippines, Venezuela and Zimbabwe. Mercury usually enters these countries legally - typically imported from countries in the European Union - although in some cases and in some years (e.g., Indonesia, Venezuela, etc.), the reported imports of Hg are far below estimated consumption. Meanwhile, the EU, while gradually replacing Hg products and processes with more environmentally benign alternatives, paradoxically continues to produce virgin Hg at government-owned mines, further exacerbating a general global oversupply of Hg - evident from its historically low market price. Political leadership is needed to avoid the transfer of excess Hg, and related health and environmental risks from the EU to third countries. Otherwise, the present situation will continue or even worsen, with no oversight or control of the global Hg trade in which the transfer of excess EU Hg to artisanal miners is favoured by low Hg prices relative to gold prices.
