The outperformance was driven by a trio of grassroots copper explorers in Kazakhstan, Peru, and the Yukon, as well as a silver explorer in southern Chile.

In Stock Talk, I review updates from a grassroots copper explorer in Australia and Bulgaria, as well as drill results from a gold-antimony play in Australia. Finally, two cash-flowing royalty generators provide updates.
