that mentions the war, but that's not the reason they stopped mining there. Even your link confirms, primarily: Grades decreased, thus costs increased, ultimately making the mine uneconomical. Secondly, water table issues.
Other gold mines continued to operate during world war eras.
Grades decreased. Veins were lost. This increased costs and made mining non-profitable.
Just getting a bit sick of the over ramping and presumptuous statements made here.. If you're gonna post please post more evidence based information Whirlpool.
