Key Information

Do not enter mining areas without proper authorization.

  • Mount Lyell Mines are in Queenstown, Tasmania, Australia, part of the West Coast Range, known for rugged landscapes.

  • The mines primarily produce copper, with significant silver and gold, especially from volcanogenic massive sulfide deposits.

  • The geology involves altered Cambrian acid volcanics, formed by ancient volcanic activity.

  • Mining started in the 1880s, focusing on copper by 1893, with periods of closure and environmental challenges.

  • Queenstown’s culture is tied to mining, with historical landmarks and a growing arts scene, despite environmental scars.

  • The area has a wet oceanic climate, with high rainfall, and mining has impacted local ecology, with ongoing remediation efforts.

Geographic Location

Mount Lyell Mines are located in Queenstown, within the West Coast municipality of Tasmania, Australia. Tasmania is an island state south of the Australian mainland, and Queenstown sits in a valley surrounded by the dramatic West Coast Range, known for its rugged, often barren "moonscape" landscapes due to historical mining. Nearby, the town of Strahan and the wilderness areas of the West Coast Range add to the region’s allure, making it a unique destination for those interested in both natural beauty and industrial heritage.

Minerals Produced

The mines are renowned for copper production, with over 1 million tonnes extracted, alongside significant amounts of silver (750 tonnes) and gold (45 tonnes). The site is particularly fascinating for mineral enthusiasts due to its volcanogenic massive sulfide (VMS) deposits, which often yield uncommon and visually striking minerals, adding to its geological richness.

Geological Structure

The geological formation at Mount Lyell is classified as volcanogenic massive sulfides, hosted by altered Cambrian acid volcanics. This indicates formation through ancient volcanic activity millions of years ago, with disseminated sulfides and varying rock types. The "Iron Blow," an iconic iron-rich gossan outcrop, was the initial discovery point, symbolizing the mine’s geological significance.

Mining History

Mining began in 1882 with gold discovery in the Linda Valley, leading to the formation of the Mount Lyell Gold Mining Company. By 1893, the focus shifted to copper, and the Mount Lyell Mining and Railway Company operated until 1994, becoming a major industrial venture. The mine saw periods of closure and reopening, with significant environmental impacts from acid mine drainage, reflecting both economic booms and challenges.

Local Culture and Characteristics

Queenstown’s identity is deeply rooted in its mining heritage, with historical landmarks like the Empire Hotel and Paragon Theatre reflecting its prosperous past. The surrounding "moonscape" of denuded hills, a result of mining and logging, is both a reminder of human impact and a tourist attraction. Despite economic fluctuations, the town is experiencing a cultural renaissance, with a growing arts community and attractions like the West Coast Wilderness Railway, originally built to transport copper.

Climate and Ecology

Queenstown has a wet oceanic climate, with an annual rainfall of around 2408 mm, making it one of Tasmania’s wettest areas, especially in winter. Summers are cool to mild, while winters are cool to cold, with occasional snow. Mining activities have significantly impacted the local ecology, with acid mine drainage affecting rivers like the Queen and King, and contaminating Macquarie Harbour. Remediation efforts since the 1990s are helping to heal the land, offering hope for ecological recovery.
