You were onto it early. They're doing it over at SOLGOD. It's actually one of the ways you get porphrys up which are large tonnage low-grade orebodies that grow and grow. If you try and drill the things out you kill yourself with dilution.
The only method of financing those tends to be JV or streaming or both. We will use our grade and low capital intensity to breakthrough.
A lot of those porphry's have a gold cap. The top has been supergene enriched because gold with the weight and lower reactivity doesn't get as transported as Cu by hot aqueous solutions particularly salty ones (containing chlorides). Porgera is a great example.
Separately as a polymetallic you mentioned ADT they used silver in their streaming. It's just that much easier with those PM that have a financial aspect so direct link to forwards (sales) and financing.
