Soon, Impala had established another contract, this time with General Motors to supply up to 300,000 ounces of platinum and 120,000 ounces of palladium annually for the period from 1974 to 1983. On the corporate side, a company called Bishopsgate Platinum Limited, of which Impala Platinum Ltd was a wholly-owned subsidiary, was listed on the Johannesburg Stock Exchange (JSE) on 26 January 1973 and on 19 October 1978, its name was changed to Impala Platinum Holdings Limited (Implats). By the early 1990s, Impala had become the world’s second largest platinumproducer, with an output of 1 million platinum ounces annually. In 1990, Implats acquired an effective interest in Western Platinum and Eastern Platinum (collectively Lonplats). In 1995, agreement was reached on a full merger with Lonplats although, this was subsequently blocked by the European Union.
