Production Report-June 1999

BROKEN HILL PROPRIETARY COMPANY LIMITED 20 July 1999 BHP Production Report Date 20 July 1999 Month June 1999 MINERALS - Steelmaking and Energy Materials month % YTD % change change Coal ('000 tonnes) 4 471 15 4 471 15 Iron Ore (West Aust) ('000 tonnes) 3 717 (17) 3 717 (17) Queensland coal production for June was higher compared to the same month last year largely reflecting lower production in June 1998 due to wet weather and a longwall changeout at Crinum. New contractual arrangements for Blackwater also contributed to higher production for the month. Higher production from Indonesia for the month was due to run of mine coal availability and increased use of mining contractors. Shipments of coal for June were 5 per cent higher than for the same month last year. Western Australia iron ore production was lower than for the same month last year due to reduced customer demand. - Non-Ferrous and Industrial Materials month % YTD % change change Copper in concentrate ('000 tonnes) 69.8 (2) 69.8 (2) Diamonds (Ekati) 117 - 117 - ('000 carats) Silver in concentrate (Cannington) ('000 ounces) 2 070 - 2 070 - Platinum in concentrate (Hartley) (ounces) 2 565 - 2 565 - Production of copper in concentrate for June was generally in line with production for the same month last year. BHP announced the cessation of production at its North American copper operations on 25 June. Escondida cathode production and shipments of cathode were higher for the month following the commissioning of the oxide leaching plant last year. Shipments of copper in concentrate were lower for the month compared to the same month last year, largely reflecting the timing of shipments at Escondida and PNG. Ekati diamond mine is at full production following commissioning of the mine operations in October last year. Cannington silver production was higher for the month compared to the same month last year as the mine ramped up to full production. BHP announced the sale of its platinum interests in Zimbabwe, including the Hartley joint venture project, on 2 June this year. - Hot Briquetted Iron month % YTD % change change Briquettes (Boodarie) 21 - 21 - ('000 tonnes) BHP's HBI plant at Port Hedland, WA, commenced production of 'Boodarie Iron (TM)' briquettes in April this year. The plant is now in the first stages of a two-year ramp-up program. Steel month % YTD % change change Raw Steel ('000 tonnes) 694 (5) 694 (5) Raw steel production was lower for June compared to the same month last year in part due to maintenance works at Port Kembla Steelworks. Newcastle Steelworks output continued to be impacted by production difficulties associated with the boiler explosion during April. Reduced steel production was partly offset by continued higher output from Delta, Ohio. Higher export despatches from Australian operations was due to timing of shipments. Petroleum month % YTD % change change Oil & Condensate ('000 barrels) 5 401 (13) 5 401 (13) Gas (including LNG) (billion cubic feet) 21.5 4 21.5 4 Oil and condensate production was lower for June compared to the same month last year reflecting the natural decline in Bass Strait production and the sale of BHP's interests in the Jabiru and Challis/Cassini fields, effective 30 June 1998. The Cossack-Pioneer (North West Shelf) remained off-line due to major refit. This was partly offset by increased production from Bruce due to higher customer nominations, and additional production wells in the Americas at Green Canyon/Ewing Bank and West Cameron.
