This is a copper ingot ready for market produced at the Nymagee copper smelter in about 1884. Nymagee is located 77 km SE of Cobar in the far west of New South Wales. Copper was discovered there in 1880 by Henry Manly and mining mainly took place between 1881 and 1894.
The copper produced at Nymagee was always remarkably pure. In 1884 there were 14,743 tons of copper ore smelted which gave 2,207 tons of copper (15 percent). At that time the population of this mining town was about 2,000. The mining site included brick kilns, a powder magazine and reverberatory furnaces for smelting the copper.
