美国巴里克公司(Barrick)计划在其内华达州的戈尔登斯特里克露天矿投入3.65亿美元以增加其年产金量。到1992年,该矿产量可达90万盎司。公司声称将提前完成贝茨开发计划,使戈尔登斯特里克金矿成为北美最大金矿之一。该计划从1989年开始实施,到2000年以前完成。 1989年1月,公司的有关人士说,巴里克公司将从波斯特露天矿和贝茨的储量中回收1040万盎司金,平均成本大约195美元/盎司。矿山的全部储量为1600万盎司金,其中1200万盎司在波斯特露天矿和贝茨矿床,其它400万盎司在波斯特深部矿床。
U.S. Barrick plans to spend $ 365 million on its Goldenstrid open pit mine in Nevada to increase its annual production. By 1992, the mine had an output of 900,000 ounces. The company said it will complete the Bates development plan ahead of schedule, making the Goldstrike Gold Mine one of the largest gold mines in North America. The plan was implemented in 1989 and completed by 2000. In January 1989, a company official said that Barrick would recover 10.4 million ounces of gold from Post Open Pit and Bates reserves at an average cost of about $ 195 an ounce. The mine’s total reserves are 16 million ounces of gold, of which 12 million ounces in the Post Opencast and Bates deposits and the other 4 million ounces in the Deep Post ore deposits.
