Sunnyside Project

Overview

Sunnyside is a copper exploration project located in Santa Cruz County, Arizona, approximately 80 kilometres southeast of Tucson, in an established North American mining jurisdiction. It is operated by Barksdale Resources Corp. and hosts copper mineralization with additional zinc-lead-silver potential.

The project sits immediately adjacent to South32's Hermosa Project, where construction of the Taylor zinc-lead-silver deposit is underway, and offers exploration potential for extensions of mineralization from the neighbouring Taylor and Peake deposits onto Sunnyside ground. Barksdale is advancing a Phase II drill program focused on the Triple C target, with recent intercepts including 0.93% copper over 60.96 metres, 0.90% copper over 60.96 metres, and a higher-grade interval of 2.75% copper and 73.5 g/t silver over 3.05 metres.

Evolve acquired a 0.5% net smelter returns royalty on Sunnyside in May 2026, adding discovery-stage optionality to the portfolio in a tier-one North American jurisdiction.
