Acprdingl ter the report' of a. Bureau of Mines survey, released today by Secretary of the Interior Oscar L. Chapm&n, most States have compensation laws for occupational diseases as well as for disabling injuries incurred on the job. The important distinction between accidental injuries and occupational diseases is' that the former occur at specific times while the latter may develop slowly over a period of years, the Bureaus report points out. Illinois was the forerunner in passing legislation designed to regulate the use of poisons in working processes and in providing compensation to workmen injured by disease.

Woods said the companys operation, located approximately 50- miles west of Hiko, is hane dling 650 tons a day of tungsten ore in. an open pit mining operation, and seeks to expand to 2150 tons. Black Rock, is employing 158 men at the present time working the property 24 hours a day, and will have 350 men on the payroll if the expansion plan is carried out, Woods told the commission. There is enough ore blocked out to carry the operation for a period of 20 years, Woods said, with the first five being open pit and the remainder underground mining. Power for the mill, and mine is how supplied from diesel units, but Woods pointed out that because of the character of the ore the cost might eventually prove too . - low-grad- low-gra- de great. A, J. Shaver, commission en- gineer, explained there was no firm power available but that' if a steam plant were built it would make it possible to serve the mining property. .

'v The board said the leasing proposal has the support of the atomic energy commission, the defense production administration and the agriculture department, but is strongly opposed by the defense materials, procurement agency (DMPA) which held that bauses and shortcomings in the functioning of the laws can be corrected by better administration and enforcement. This has been the contention of the mining industry, but the federal agendes responsible for administration of the law, particularly the bureau of land management, have shown more concern over getting the laws changed than in enforcing existing legislation. Reduction or elimination of tariffs on metals which are produced in substantial quantities in this country, such as lead and zinc, is also opposed by the mining industry, because, with inflation and high labor costs, domestic producers are unable to compete with foreign producers which have the advantage ore deposits and of higher-grad- e ' labor. cheap native . competition to the detriment of domestic mining operations, mining men contend. Other steps urged by the board were: Greater partidpation by private enterprise in the development and use of atomic energy as a source of power; United States partidpation with Canada in the St. Lawrence seaway; and legislatioin prescribing policy to be followed by the department of interior in managing offshore oil lands.
