Exploitation
The Browns deposit is currently being developed as a major base metals mine by Compass Resources NL, an Australian public company, in joint venture with Hunan Nonferrous Metals Corporation, a Chinese government company.
The mine is due to be complete in August 2008, after suffering cost escalation and construction delays, and will produce 15,000 tonnes of copper, 4,000 tonnes of cobalt and 4,000 tonnes of nickel per annum, with a mine life of 30 years, mining the oxide and supergene ores. The processing plant includes solvent extraction and electrowinning processing equipment.
The sulfide resources are hosted beneath the supergene and oxide zone ores and as yet no processing plant has been built to treat the pristine sulfide ores.
On 29 January 2009, Compass Resources went into voluntary administration, while in the process of commissioning the mine.

Famous quotes containing the word exploitation:
“The mother’s battle for her child—with sickness, with poverty, with war, with all the forces of exploitation and callousness that cheapen human life—needs to become a common human battle, waged in love and in the passion for survival.”
—Adrienne Rich (20th century)
“The only phenomenon with which writing has always been concomitant is the creation of cities and empires, that is the integration of large numbers of individuals into a political system, and their grading into castes or classes.... It seems to have favored the exploitation of human beings rather than their enlightenment.”
—Claude Lévi-Strauss (b. 1908)
“Communism is inequality, but not as property is. Property is exploitation of the weak by the strong. Communism is exploitation of the strong by the weak.”
—Pierre-Joseph Proudhon (1809–1865)
