Abstract
In this project report, economic evaluation techniques and investment
decision methods are studied. Their application to the gold mine
residue reclamation projects of East Rand Gold and Uranium Company
(Ergo), an associate of Anglo American Corporation (AAC), is
considered.
AAC has been active in dump reclamation since 1953 and by 1982 it was
operating three plants on the Rand, namely Ergo, Simmergo and Sallies
The development, by AAC and Ergo1s metallurgists, of the
carbon-in~leach process created additional investment opportunities.
These opportunities were economically evaluated using rate of return
analysis and other methods to determine their relative merits. The
economic evaluation exercises indicated which investments ought to be
undertaken to maximise the profits arising from the amounts invested.
Legal and other aspects influencing the decision-making process are
studied, as well as the financing of the capital expenditure
