Spring Peak Project

Large and under-explored
precious metal system with a clear analog
immediately next door at Hecla’s Aurora Mine

Spring Peak Overview

Several high-priority drill targets defined by OceanaGold before exiting Nevada for non-technical reasons
High-quality exploration database, including extensive CSMAT and soil surveys collected by OceanaGold in 2019
Infrastructure at nearby Aurora includes a 350 ton per day mill, several production water wells, and high-voltage three-phase power
Option to acquire 100% ownership

Shallow historic RC drilling consistently encountered anomalous gold values, but failed to test for high-grade vein mineralization at depth

Historic rock sampling on the Property returned values up to 35.7 g/t gold in banded epithermal quartz veins
5-metre thick silica sinter indicates the system is fully preserved
Project is fully permitted and drill-ready with drilling expected to commence August 2021
* Historic production figures from Vikre et al., 2015 The qualified person has been unable to verify the information on the adjacent Property.  Mineralization hosted on adjacent and/or nearby and/or geologically similar properties is not necessarily indicative of mineralization hosted on the Company’s Property.
