The Mining & Geological Journal was produced by the Department of Mines, Victoria twice a year, during the period 1937 to 1972. It was an official publication of the Victorian Government, Department of Mines, devoted to issues and events surrounding mining and metallurgical engineering in Victoria along with education, research and innovations in mining. The journal also included advertisements and references to business interests. Green and white cover, black text. On cover: 'Mining & Geological Journal' Volume 6, Number 1. 1959 - 1960.

This specimen was recovered from the Nigretta Falls (previously named the Upper Wannon Falls), Victoria. The falls are fed by the Wannon River that has its head waters in the Grampians mountains. Approx. 10km upstream of the Wannon Falls, Nigretta is a multi-channel segmented cascade of smaller drops and bounces guided by patterns of joints in a much older (Devonian) rhyolitic volcanic rock. Both the Wannon and Nigretta Falls are iconic landscape features, entrenched in the history and identity of the region. These falls are particularly rare as they are the product of volcanic activity, which is unique in the context of the Volcanic Plain of Victoria. Waterfalls of this capacity are generally associated with the Uplands areas of Victoria, rather than the edges of the Volcanic Plain. 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 solid, dark grey mineral specimen with pale terracotta coloured inclusions. Rhyodacite is a volcanic rock intermediate in composition between dacite and rhyolite. Rhyodacites form from rapid cooling of lava relatively rich in silica and low in alkali metal oxides.GEOLOGICAL SURVEY / R / S 55 FELSTONE PORPHYburke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, porphyritic rhyodacite, lava, nigretta falls, upper wannon falls, dacite, rhyolite, volcanic geology

The A1 Gold Mine is located north of Woods Point, near Jamieson, in the Upper Goulburn region of Victoria. Gold was discovered at the A1 site in 1861 and mining operations began in 1864. The A1 Mine Settlement refers to a small township known variously as Castle Reef, Castle Point, and Raspberry Creek, which developed in the 1860s around mining industry centred on a crushing machine that worked the three gold reefs in the area. Historically, the name "A1"referred to the high quality of gold found in the quartz reefs at depths of at least two thousand feet. Along with the Morning Star mine at Woods Point, the A1 gold mine produced almost sixty percent of Victoria's gold output in the 1950s to 1970s and continued operating until 1992 when it went into administration. Operations at the site were revived in 2016 and the A1 Mine is now considered one of Victoria's premier gold mines. The A1 mine is part of the extensive and prospective Lachlan Fold Belt, a north-west trending belt of tightly folded Early Devonian sedimentary rocks extending from New South Wales to Victoria. Mineralisation is hosted within or immediately adjacent to diorite dykes. Contemporary development of the 'Queens Lode' at the A1 mine signals a move from high-grade, narrow vein airleg mining into larger scale, mechanical mining designed to increase ore production volume. This original, undated photograph of the A1 Mine appears to depict an area or phase of disuse or abandonment. The aged and humble appearance of the cottage suggests association with the historical A1 Mine Settlement, therefore the image may have been taken prior to the 1950s-1970s revival period in which the A1 mine is known to have produced high gold yields. The photograph contributes to our understanding of the A1 Gold Mine's impact on the landscape and the social, environmental impacts of mining on communities and may be compared with others in the Burke Museum's extensive collection of mining photographs to deepen our understanding of mining in the Jamieson area.Black and white rectangular photograph printed on photographic paperReverse: 5577 / A1 Mine / Near Jamieson / Vic. /burke museum, beechworth museum, beechworth, gold fields, gold rush, victorian gold rush, mining tunnels, gold ming history, colonial australia, australian gold rushes, mining technology, beechworth historic district, indigo gold trail, indigo shire, upper goulburn shire, jamieson, woods point-walhalla goldfield, a1 gold mine, victorian high country, modern mining methods, orogenic gold province, gold mineralisation, devonian, dykes
