Agate occurs when amygdales (gas pockets) form in the upper levels of basaltic lava flows. If these pockets or bubbles are iniltrated by water bearing silica in solution, the fluid dries and hardens in layers, forming round or egg shaped nodules or geodes within the rocky matrix. Agate is formed of a silica mineral chalcedony similar to quartz. Although relatively common and semi-precious, agate has been prized since at least 1450 BC - an intricately carved agate seal was found in the 2015 excavation of a grave belonging to a Mycenaeum priest or warrior near Pylos in Greece. Agate is also used in jewellery and other decorative or ritual purposes due to its often striking appearance. Quartz is found all over Australia, including Beechworth in Victoria. It is formed in deep-seated igneous rocks and crystallized through hot aqueous solutions. It can have two forms; Microcrystalline quartz or Crystalline quartz. Microcrystalline quartz is a fine grain quartz where crystalline quartz is often a large crystal. The colour of quartz can vary. These specimens were collected in Victoria in the vicinity of the Burke Museum. Victoria and other regions of Australia were surveyed for sites of potential mineral wealth throughout the 19th Century. The identification of sites containing valuable commodities such as gold, iron ore and gemstones in a locality had the potential to shape the development and history of communities and industries in the area. The discovery of gold in Victoria, for instance, had a significant influence on the development of the area now known as 'the goldfields', including Beechworth; the city of Melbourne and Victoria as a whole.The specimens are significant as examples of surveying activity undertaken to assess and direct the development of the mineral resource industries in Victoria and Australia, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.Geological specimens of Agate and Quartz respectively; the fist-sized piece of Agate has peach/coral colouring with grey concentric patterning and the smaller piece of quartz is a uniform yellow/orange shade.

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 State Battery was the central component in the gold mining of this area from the 1920s. The battery crushed the gold bearing quartz extracted from the mines and was a sizeable weatherboard building enclosing the engine and stampers. All that now remains are the bases for the machinery that comprised the battery, one timber and a couple of concrete bases and the nearby dam, which supplied water. However the historic significance of the site remains and is enhanced by the Queenstown Cemetery on the other side of Smiths Gully Road". - Bick Study 1922 This site is now the Peter Franke Reserve and is managed by Parks Victoria Photo Source: The Leader, Nov. 2nd, 1929This photo forms part of a collection of photographs gathered by the Shire of Eltham for their centenary project book,"Pioneers and Painters: 100 years of the Shire of Eltham" by Alan Marshall (1971).

Galena is the natural compound of lead and classed as a sulphide, it crystallises in a cubic pattern and its chemical formula is PbS. Galena is a primary source of both lead and silver. This specimen of Galena comes from Broken Hill. Broken Hill has one of the world’s largest and most significant deposit of ore for the production of lead. Mining of Galena at Broken Hill began with the staking of land by Charles Rasp in 1883. By the following year, in 1884, Rasp and six others had formed Broken Hill Mining Company. Broken Hill Mining Company eventually evolved into BHP group limited and is currently the largest mining company in the world and the largest company in Australia. There is archaeological evidence from artefacts discovered in Turkey that humans have been extracting lead from galena by the process of smelting since at least 6500 BCE. This specimen also has quartz on the top surface which is frequently discovered alongside Galena. This mineral specimen is of historic significance as a sample of Galena extracted from Broken Hill during the 19th century. Mining for Galena in Broken Hill begin in 1883 by Charles Rasp and evolved into the world’s largest mining company – BHP Group Limited. Broken Hill is one of the world’s most significant deposits of ore for the production of lead. 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.A flat, hand-sized, grey sulphide specimen that is the natural compound of lead with a quartz formation on the top surface.

Tourmaline specimens are members of a crystalline silicate mineral group based on boron but influenced by elements including aluminium, iron, magnesium, sodium, lithium, or potassium. Specimens present a wide variety of colours and forms according to the specific mix of these elements. Tourmalines are semi-precious gemstones with many applications, including commercial jewellery production. The word 'tourmaline' derives from the Sinhalese term for the carnelian or red-shaded specimens, "tōramalli". This specimen has been classified by geologists as 'Black Schoalou/Tourmaline in quartz'. Schoalou may equate to a common black-hued type of Tourmaline associated since around 1400 with mines in Saxony, Germany near a village called Schorl (today's Zchorlau). If this specimen is part of the 'Schorl' species of tourmaline it is a member of the most common group of Tourmalines, a divalent sodium ion influenced group accounting for 95% of specimens. On assessment, it was noted that the crossed lines (XIs) of this tourmaline have been fractured and rehealed by the quartz matrix in which the tourmaline rests. This item is significant as an example of its type of gemstone and the geological processes leading to its formation.
