Qualified comments: |
(Applies to: discovery and development) Discovery in 1908; magnetometer survey in 1956; diamond drilling done in 1960 and 1961 outlined 4.26 Mt of iron ore; a part of the deposit below the open pit was uneconomic. Open pit mining 1962 to 1966, then underground till 1968; total 3,864,434 t mined; 3,938,702 t milled; iron recovered: 2,070,953 t; figures include small tonnage from nearby Rose and Adonis properties. |
