Interest in gold in W.A. increased following the 1849 California and 1850's Victorian rushes. A rich find made by Arthur Bayley and William Ford during 1892, in Coolgardie, inspired a small rush. A large amount of gold (over 500 oz) was initially found on Bayley's Reward lease above a quartz reef. Within a month, 3000 oz had been found by 400 prospectors. Soon after, in June 1893, Patrick Hannan, Tom Flanagan and Daniel O'Shea discovered a rich deposit of gold at Mt. Charlotte, Kalgoorlie. This initiated a rush resulting in the discovery of the Kalgoorlie-Boulder "Golden Mile." From here, gold exploration spread throughout the state. The introduction of ground cancelling metal detectors to Australia in 1974 created renewed interest in prospecting that, together with the high price of gold, led to the prospecting boom of the late 1970's and early 80's. The largest nugget ever found in W.A. is the Golden Eagle by Larcombe at Larkinville in 1932. It weighed 1135 oz. Alluvial and reef gold occurs in the Yilgarn, Pilbara and Kimberley districts. Approximately 95% of the states gold production has come from the Yilgarn district, exceeding the Pilbara and Kimberley by far.

Consolidated Gold Fields was a major British mining house founded by Cecil Rhodes in 1892. Diversifying from its South African gold interests, the company invested widely during the following century. This included investments in the Western Australian gold sector from the 1920s and exploration and mining activities elsewhere in Australia and the Territory of New Guinea. In the 1960s, Consolidated Gold Fields Australia (CGFA) was formed. CGFA had ambitious plans and the financial backing from London to establish itself as one of the main diversified mining companies in Australia. Investments were held in the historic Mount Lyell Mining and Railway Company, in Renison, and it was one of the first groups to develop iron ore deposits in the Pilbara of Western Australia. It also acquired a major interest in mineral sands. While the London-based Consolidated Gold Fields ceased to exist in 1989, taken over and dismembered by renowned corporate raider Hanson Plc, its Australian subsidiary, renamed Renison Goldfields Consolidated (RGC), continued for another nine years as a diversified mining group before it suffered its own corporate demise, facilitated by Hanson. CGFA and RGC were important participants in Australia¿s post¿World War?II mining sector. This book is a history of a once great British mining-finance house and its investments in Australia. Consolidated Gold Fields had a rich and broad history in Australia; its ultimate fate did not demonstrate its potential as an Australian mining company.

Within the last decade, the high and continuing demand for gold has prompted a global gold rush on a scale never before seen, not even in the heady days of Ballarat, California and the Yukon. Gold is being sought on every continent and, with very few exceptions, in every country around the world. Such interest and fierce competition has demanded considerable innovation and improvement in exploration techniques paralleled by a rapid expansion of the geological database and consequent genetic modelling for the many different types of gold deposits now recognized. This proliferation of data has swamped the literature and left explorationist and academic alike unable to sift more than a small proportion of the accumulating information. This new book represents an attempt to address this major problem by providing succinct syntheses ofall major aspects ofgold metallogeny and exploration, ranging from the chemical distribution of gold in the Earth's crust, and the hydrothermal chemistry of gold, to Archaean and Phanerozoic lode deposits, epithermal environments, chemical sediments, and placer deposits, and culminates in chapters devoted to geochemical and geophysical exploration, and the economics of gold deposits. Each chapter is written by geoscientists who are acknowledged internationally in their respective fields, thus guaranteeing a broad yet up-to-date coverage. In addition, each chapter is accompanied by reference lists which provide readers with access to the most pertinent and useful publications.
