Written Answers. - North Clare Phosphate Mines.
334.
In reply to a previous question on 31 May 1978, my predecessor informed the Deputy that tests were being carried out to ascertain the nature and quality of sample rock phosphate material yielded by drilling and other field work in the north Clare area. Following receipt of the results of these tests the Clare phosphate working group recommended the engagement of consultants to assess the economic viability of the phosphate deposits.
A report furnished by the consultants indicated that some four million tons of phosphate rock, spread over four separate locations, has been delineated in north Clare. However, the deposits are of relatively low grade ore, and the consultants have advised that anticipation revenues from the sale of the material, relative to extraction costs, would not be such as to enable the deposits to be developed on a viable basis for industrial usage, such as in chemical or fertiliser manufacture. The question of further exploration work in the area, aimed at possibly locating larger, high-grade deposits, is being examined at present.
