McCormick, the divisions manager of production. According to McCormick, the period since last April, when the Company announced plans for the $70 million facilities at Rowley, Utah, has been marked progress in by exceptional beneficiation of Lake brines. Over 600,000 tons of magnesium chloride rich brine concentrate have been accumulated in a holding pond on the plant property, or the equivalent of ablut 1 50,000 tons of magnesium metal. An annual output of 45,000 tons of metal is planned for the plant, scheduled for operation late in 1971. This will boost U.S. production of the light metal by about a third.

Gulf Resources and Chemical Corp. Allen, Gulf H. president, said the lower silver prices offset the earnings of Bunker which were down, while sales were $3 million more than the previous year. Although ore production at the increased, Allen noted, mine shaft . attained only in part through increased silver prices. Earnings will also benefit from important steps being taken to reach levels of efficiency acceptable to Gulf, he added. They will include improved smelting and refining processes, expanding mining activities to lessen use of purchased ores and instituting new management techniques. construction and slow development of a deep orebody in the Star Mine decreased the grade of zinc and lead ores.

These factors plus high gold prices resulted in a substantial profit contribution, Allen pointed out.
