Looks like a typo from Haoma.
888g/t gold and 946g/t platinum
Should read...
888 mg/t gold and 946 mg/t platinum
If no typo, I'll be out at Mt Webber with my wheelbarrow and tuck a few tonnes of tailings away in my backyard. A few dozen kilos of gold and platinum for a rainy day.
Conclusion: utter nonesense.
