Book, The Economics of Mining (Non-Ferrous Metals), 1938, 1938
The book was used by Charles Bacon who studied at the University of Nevada in the late 1930s/early 1940s. Bacon worked at Bunker Hill Mines and Kellogg Idaho, before arriving in Australian in 1951. He worked for CN Myers, a company involved with paper converting. CN Myers was a family business (on Charles Bacon's maternal line). The Mackay School of Mines, Nevada was established in 1908. At the time of writing this mook T.J. Hoover was Professor of Mining and Metallurgy and Dean of the School of Engineering at Stanford University. Theodore Jesse Hoover, brother of the 31st President of the United States, was born in West Branch, Iowa, on January 28, 1871. He attended Stanford and received the Bachelor of Arts degree in Geology and Mining in 1901. Following graduation his professional career started with the position of assayer for the Keystone Consolidated Mining Company. After one year, he became assistant manager for the Standard Consolidated Mine, and a year later he was promoted to manager of the operation. In 1907 Hoover went to London as general manager of Minerals Separation, Ltd. This company was developing the froth flotation process for recovering minerals from ores. Hoover took an active part in the development of the flotation concentration process and authored one of the first books on the concentration of ores by flotation. After four years with Minerals Separation, Ltd., Hoover entered private practice as a consulting mining and metallurgical engineer with offices in London and in San Francisco. He was very successful and held positions of consulting engineer, managing director, director, and president of many mining companies in America, Europe, Asia, Africa, and Australia. He returned to Stanford in 1919 as Professor of Mining and Metallurgy and Executive Head of the Department of Mining and Metallurgy. His experience and ability in organization made him a natural leader. He was influential in the formation of the School of Engineering at Stanford. The School was formed in 1925 and he was made dean, a position he held until his retirement in 1936. As dean of engineering, he promoted a broad fundamental training program for undergraduate engineering students. Under his guidance, emphasis was placed upon graduate work and he was responsible for developing strong graduate engineering curricula at Stanford. While dean he continued teaching and his course, "The Economics of Mining," developed into a book which was published in 1933. He became interested in the functions of engineers and, with Professor Fish, wrote a book entitled "The Engineering Profession" which was published in 1940 and revised in 1950. In addition to his academic activities he was generous in his hospitality. Faculty and students alike enjoyed the annual field day and barbecue at his Rancho del Oso, near Santa Cruz. He was widely read and had a lively interest in all the things he encountered. He speculated on the antiquity of man and man's early production processes. To verify an idea regarding flint tools, he studied their shapes and became proficient in making arrow heads. He was also interested in wild life, and was one of the founding members of the Cooper Ornithological Society.

The Beechworth Burke Museum
Geological specimen - Chalcopyrite
This specimen originated from Mount Lyell on the west coast of Tasmania, where a large group of open cut and underground copper-silver-gold mines began operating in 1883. Between 1893-1994, the Mt Lyell Mining and Railway Company were responsible for operations. The Mt Lyell copper-gold mines produce some excellent crystallised specimens of chalcopyrite and other minerals. The deposits are generally considered to be of Cambrian volcanic origin, but there are indications of Devonian granitic influence on the ores, plus local remobilisation during Devonian deformation. Over 120 million tonnes of ore was produced from several workings, including the main Prince Lyell mine and the North Lyell mine, which was also of great importance. The Mount Lyell mines have a long history of human and environmental disasters, including the 1912 North Lyell fire that killed 42 miners, and two separate incidents in 2013 in which three people lost their lives. The environmental impacts from this complex of mines are extensive, with waste tailings and heavy metal contamination flowing directly into the King and Queen River catchments. In 1954, the eminent Australian historian, Geoffrey Blainey, published 'The Peaks of Lyell' which delves into the history of the 1912 North Mount Lyell Disaster.Chalcopyrite does not contain the most copper in its structure relative to other minerals, but it is the most important copper ore since it can be found in many localities and occurs in a variety of ore types. The brassy-yellow colours in Chalcopyrite mean it is often confused with pyrites and gold, leading to use of the term, "fool's gold." Chalcopyrite has been the primary ore of copper since smelting began five thousand years ago. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.This hand sized solid mineral specimen has shades of brass-yellow with spots of iridescent green-black tarnish. Chalcopyrite is a copper iron sulphide mineral and a major ore of copper common in sulphide veins and disseminated in igneous rocks. Chalcopyrite has a hardness of 3.5-4 on the Mohs Scale. It is a member of the tetragonal crystal system and has metallic lustre and opaque transparency.burke museum, beechworth, indigo shire, beechworth museum, geology, geological specimen, chalcopyrite, copper pyrites, copper mining, tasmanian geology, mount lyell, mount lyell mines, fools gold, mohs scale, crystals, minerals, historical geological collection, victorian geological survey, a.r.c selwyn, gold rush, van diemans land -

The Beechworth Burke Museum
Geological specimen - Copper Ore
This specimen was recovered from Silverton Mine in Broken Hill, New South Wales. Otherwise known as the 'Day Dream Mine', the Silverton Mine was first established in 1883, when silver and lead deposits where discovered. Within a few short years, the population of Broken Hill reached 3000 people. As of today the Silverton Mine is still open, and has produced over 200 million tonnes of ore, which has generated over $100 billion. The Silverton Mine was also famous for a number of specimens such as silver, iron and zinc.Copper is considered to be a rare ore in that finding it in its pure form is rare. Nowadays when mining for Copper it is often found in mixed in with other minerals or it is recycled from use. Moreover, Copper is found in a range of everyday uses such as coins, cookware, pipes, heating conductors and anything that generate electricity. The fact that Copper is heat a heat conductor, electricity conductor and it does not corrode easily, makes this ore a versatile and useful. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Copper is typically found as nuggets in the ground. It can be found in a range of forms such as its native state; mixed with other ores, such as zinc and iron; as porphyry copper deposits; and as major deposits. Porphyry deposits are when the mineral is scattered evenly throughout the rock. Major deposits are when the mineral is scattered amongst other minerals.burke museum, beechworth, indigo shire, beechworth musum, geological, geological specimen, mineraology, copper, copper ore, copper ore speciment, broken hill, new south wales -

The Beechworth Burke Museum
Geological specimen - Gold-Sulphide Ore
This particular specimen was recovered from two hundred feet down in the Golden Mile in Kalgoorlie, Western Australia. The Golden Mile, named after the estimated sixty million ounces of gold worth around one hundred billion dollars, was the birthplace of the largest gold rush in Australia almost one hundred and thirty years ago when William Brookman and Samuel Pearce leased the Great Boulder mine. The Golden Mile is also the home of the Super Pit, Australia's most well-known mine.The majority of gold deposits will form as a native metal, however, on occasion, it can form a compound with another element, in this case, sulphur. Therefore, this specimen is a rare example of gold naturally forming into a compound mineral with sulphur. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.

Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A small gold-sulphide ore mineral specimen in shades of silver and grey with flecks of gold. Precious metals are often found in Sulphide Ores, as sulphides usually bind to these metals. They are also extremely symmetrical in crystaline form. Gold-Sulphide Ore occurs when gold forms a natural compound with other elements. In this form, gold can be present in one of two ways. It can be fully immersed in the sulphide, or a portion may be partially free. This specimen has minimal gold visible, with only a few flecks being partially visible.burke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, mineralogy, gold-sulphide ore -
Queenscliffe Maritime Museum
Geological specimen - Copper ore
The Empress of the Sea was a magnificent three masted, square rigged, wooden sailing clipper ship built in Boston, USA. The Empress of the Sea is historically and archaeologically significant as it was one of Donald Mackay's famous wooden clipper ships, i.e. representative of a particular design or type. It was also associated with both the Black Ball and White Star Lines of Australian Packets, which carried thousands of immigrants from Britain to Australia. The Empress of the Sea caught fire at Queenscliff at 4 am on 19 December 1861. When the officer of the watch attempted to extinguish the fire they found fire pump handles missing and buckets ineffective. Fire became out of control and the ship was sailed from anchorage and ran ashore at Point Nepean. Ship rolled over onto starboard side by force of the tide and the shifting ballast. The port side was burnt to the copper. The Empress of the Sea lies in 5 metres (16 feet) to 7 metres (23 feet) of water, 700 metres (2,297 feet) offshore from Nepean Bay, Port Phillip. The site covers an area 150 metres (492 feet) long and 50 metres (164 feet) wide. The bow lies towards the south-west.

Geological specimen - Rhodonite with Galena and Sphalerite
This specimen is from Broken Hill, NSW. Galena is a natural mineral form of lead sulphide and is often found associated with sphalerite, calcite, and fluorite. Galena is an important lead ore mineral, and, in some regions, it is also an important mineral associated with silver ore. Sphalerite is a sulphide mineral that is the main ore of zinc. Rhodonite is an uncommon mineral once used as an ore of manganese in India, however today the scarcity and fragility of the crystals mean it is primarily used as lapidary materials or mineral specimens. In 1883, Charles Rasp who was a boundary rider at the time, discovered what he thought were deposits of tin but were in fact samples of silver and lead. He and six others went on to set up the first mining company in Broken Hill (BHP). The ore body became the largest and richest of its kind in the world mining ore worth more than 42,000 pounds in its first year. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study. Galena contains lead and silver, Sphalerite contains zinc. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.
