Here is the Western Australia Fees and Charges table for mining leases: https://www.dmp.wa.gov.au/Documents/Minerals/Minerals-Feesandcharges_2021-22.pdf
Looks like the costs total $122/yr/hectare; $22/yr in rent, and $100/yr in minimum annual expenditure.
I've not found a hectare total for the mining claims of Vango's Marymia project. Does anyone know what it is?
