World developments in lead and zinc are examined for 1970‐90 and projections presented for 1995. Although lead consumption has Increased during the period under review, lead mine production has been on a decline, the differences being made up from secondary lead sources. Lead mine production is projected to be steady to 1995, with increased consumption continuing to be met from secondary sources. Zinc mine production increased at a trend rate of about 1% per year between 1970 and 1990, but for 1991‐95, production is expected to grow at a lower rate. For 1990‐95 zinc consumption is expected to grow at a rate of 2.3%. This modest mine production increase to 1995 is unlikely to be adequate to meet growth in MEC zinc consumption.
