Correction (April 17, 2000)

In our April 10 issue, we incorrectly stated that the Majistral deposit in Peru, held by Inca Pacific Resources (IP-V), has reserves of 500 million tonnes averaging 1.2% copper, 1% zinc, and 0.03% molybdenum, plus 11 grams silver per tonne. These reserves belong to the nearby Antamina copper-zinc deposit, being developed jointly by Noranda (NOR-T), Rio Algom (ROM-T), Teck (TEK-T) and Mitsubishi.
