RE:MARI and FILOf course any good project like Marimaca and Filo going through exploration drilling has potential upside. Which has more? I think a more important question is which one has more downside from here?
Hint: how big was Barrick's write off on Pascua Lama and what were the reasons. Also what country is each project in. And is the capex expenditure something that can be overcome.
Not knocking FIL but my money looks for the best risk-reward profile rather than what may be the best potential reward profile.
