What should we do with Australia’s 50000 abandoned mines?

This could include:

• further mineral extraction via secondary mining such as reprocessing tailings.
• industrial archaeological heritage conservation and tourism.
• unique habitats for biodiversity enhancement.
• collaborative research into innovative solutions to contamination problems which could guide the broader industry.

Can you explore abandoned mines?

Mine exploration is a hobby in which people visit abandoned mines, quarries, and sometimes operational mines. Enthusiasts usually engage in such activities for the purpose of exploration and documentation, sometimes through the use of surveying and photography.

What next for mining in Australia’s future?

Within the next decade, several large mines in Australia will reach the end of their lifecycle. Ensuring that mine closures are done responsibly and with the least impact on regional mine-dependent economies is the focus of the newly funded Cooperative Research Centre for Transformations in Mining Economies (CRC-TiME).

How many abandoned mines are there in Australia?

What is the economic impact of mine relinquishments on Australian mining?

Part of this economic impact, according to the academician, could be driven from increased certainty around mine relinquishments, resulting in more investor confidence. “One of the issues facing Australia’s mining industry is that there are very few cases of successfully closed and relinquished sites.
