The CopperString project envisages an 840km electricity transmission line connecting Mount Isa to the national electricity market, which is vital for tapping into renewable energy resources and supporting critical minerals extraction in Queensland, reports michaelwest.com.au.

Federal MP Bob Katter argues the project’s importance for local mining operations and the regional economy, with energy costs being crucial for mining viability.

Despite the lack of progress over 15 years, Katter insists that the project remains a vital factor for industrial survival and development in the region.
