Arsenopyrite is one of the most common arsenic sulfide minerals, alongside orpiment and realgar. In its purest form, it becomes toxic as a result of a 46.0% arsenic makeup. Arsenopyrite occurs naturally in sulfide-bearing mineral deposits and is commonly found alongside gold deposits. This specimen was discovered in Maldon, Victoria, in the Maldon gold field. This mine is an important gold producer which was first mined in 1857. Between this initial date and 1926, 58 tonnes of gold was produced. The town of Maldon was designated Australia's first notable town, and has maintained its 19th-century appearance since the says of the gold rush. This mineral makes up a small part of the large amounts of minerals which has been excavated from the Maldon gold mines. The Maldon Goldfield alone has produced an excess of 1.7 million ounces of Australia's highest grade gold. This mineral represents not only the richness of the area, but also the significant impacts the gold rush had on the town.A solid iron arsenic sulfide mineral with shades of white, grey and blackburke museum, mineral, arsenopyrite, victoria, maldon, maldon victoria

The mining class visited the Last Chance on the afternoon of Thursday, 8th June, under the guidance of Mr Kirby, the mine manager. Mr Campbell, the photographic instructor, also dared the perils of the deep in order to take some flashlight photos. As this was Mr Campbell's first visit below, several difficulties which he did not now existed prevented success. The students all ranged themselves in poetic and heroic attitudes for the first flashlight, but the development of the plate showed only the light from the candles and the moisture on the lens. The next two tries were better, but were under-exposed, and of no value, except as experience. Two gentlemen from England also went below with the students, but history repeated itself and Australia won the "test." The Englishmen left early. Mr Hart secured a fine specimen of arsenopyrite and indicator slate; also a bootlace, the property of a much-vexed miner, whose boots Mr Hart had borrowed. Horrors! Mr Hart steal a bootlace! Impossible! However, a tragedy was averted by the miner securing a new lace, and he was at once all smiles - so were the students. Mr Campbell took a photo of the students dressed for the occasion, and some were flattered, and some looked very like the universal "Weary Willie".
