Economic study identifies Green Bay as a top-tier global copper mine project

A new economic study by FireFly has identified Green Bay as one of the world's best undeveloped copper projects, with the potential to become one of the largest copper mines once production begins Daily Herald Tribune. The Preliminary Economic Assessment shows the project has exceptional scale, ore grade, long mine life, and strong financial returns that could deliver robust profits National Post.
Green Bay is located in Australia and stands out among global copper projects The Sudbury Star. Managing Director Steve Parsons stated that the deposit has what it takes to rank among the world's largest copper mines when operations start The Whig. The project includes significant gold and silver alongside copper, adding multiple revenue streams.
The economic study is preliminary in nature and includes resource estimates calculated following strict international guidelines Fairview Post. Metal equivalents were based on copper priced at US$10,626 per tonne, gold at $3,587 per ounce, and silver at £50.22 per ounce Brantford Expositor. The estimates follow the JORC Code 2012 and NI 43-101 standards, which govern how mining companies report mineral resources.
The study evaluated two operating scenarios: a base case processing 1.8 million tonnes annually and an alternative handling 4.6 million tonnes per year Market Screener. Both scenarios showed positive financial returns, making the project economically viable at current commodity prices Cold Lake Sun. The findings suggest Green Bay could move toward development and production in coming years.
The study includes Inferred Mineral Resources, which are considered too uncertain geologically to be classified as proven Ore Reserves Pincher Creek Echo. This means the actual ore amounts and grades could differ from estimates once mining begins Seaforth Huron Expositor. Investors should understand that preliminary studies carry more risk than feasibility studies based on more drilling data.
