and, accompanied by prospector Ken McCamey, followed the iron ore over a distance of 112 km. He soon came to realise that he had stumbled across reserves of iron ore so vast that they could supply the entire world, thus confirming the discovery of the geologist Harry Page Woodward, who after his survey asserted: After 1920 development of the Yampi Sound deposits started but exports to Japan were curtailed by the Commonwealth Government in 1938. Prospecting and exploration of other ore deposits continued until 1952 where an agreement between the Government of Western Australia and BHP to build a steel mill and smelter in Kwinana was established. All other iron ore, known or unknown, was reserved to the Crown for 9 years. Representations were made to the Commonwealth Government to have the embargo lifted and in 1960 Limited approval was granted for the export of iron ore from non-BHP deposits. This sparked a wave of intensive prospecting and exploration concentrated in the North West, the Hamersley Ranges in particular, where formation had been known but ore bodies not yet delineated. At this time Hancock revealed his discovery. Hancock had lobbied furiously for a decade to get the ban lifted and in 1961 was finally able to reveal his discovery and stake his claim. In the mid sixties Hancock turned once more to Peter Wright and the pair entered into a deal with mining giant Rio Tinto Group to develop the iron ore find. Hancock named it "Hope Downs" after his wife. Under the terms of the deal Rio Tinto set up and still administer a mine in the area. Wright and Hancock walked away with annual royalties of A$25 million, split evenly between the two men. In 1990, Hancock was estimated by Business Review Weekly to be worth a minimum of A$125 million. Political activity Although Lang Hancock never aspired to political office, he held strong conservative political views and often entered the political arena. In addition to his activities in the 1950s, lobbying against government restrictions on the mining of iron ore, Hancock donated considerable sums of money to politicians of many political stripes. His political views aligned most closely with the Liberal and National Parties of Australia. He was a good friend and strong supporter of Queensland Premier Joh Bjelke-Petersen and donated A$632,000 to the Queensland National Party while Sir Joh was in charge. He gave A$314,000 to
