Are there examples from abroad where mining has strengthened communities?

Yes, many. In Canada, towns like Sudbury have transformed from polluted mining towns into modern cities with universities, cultural life, and green industries, supported by the mining sector. In Finland, towns like Outokumpu and Sotkamo have benefited from mining with jobs, housing, and schools. In Australia, especially Western Australia, mining revenues have supported hospitals, roads, and sports arenas in rural areas.
