The Feasibility Study''s base case uses a gold price of 1,250 per ounce and generates a LifeofMine aftertax free cash flow of 150 million, an internal rate of return (IRR) of 23%, an aftertax net present value (NPV5%) of 54 million, an average annual aftertax cash flow from operations of 21 million per year, an average operating margin per ounce of 364 and a payback period of years.
Currently, around 75% of gold extracted from ore is processed using the hazardous chemicals of cyanide or mercury, which are toxic to humans and the environment. These chemicals are often contained in large storage tanks and, once used, expelled into large tailing dams that can potentially leach into the local surrounds or, worse, burst as we''ve seen in recent years in Brazil and Canada.

Compared to the mountainous pile of 17 tons of gold ores, more gold can be recovered from this heap during cell phone recycling than what can be extracted from 17 tons of gold ores. A ton of cell phones can yield as much as 280 grams of gold, about 140 grams of platinum and palladium, and 140 kilograms of copper. There''s also plastic and glass that can be recycled from used cell phones.

Gold dissolves in aqua regia, a mixture of hydrochloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from lowgrade ore. The degree of purity of native gold, bullion (bars or ingots of unrefined gold), and refined gold is stated in terms of gold ...
Gold production declined by 14% to 12,714kg (409,000oz) (2006: 14,736kg (474,000oz)), owing to a higherthanexpected fall in the volumes of ore mined. This was due to increased seismic activity in the vicinity of the CLR shaft pillar which is being mined, and at several highgrade production panels, where production was halted for limited periods during the course of the year. Both face ...
