Highland Project

Epithermal vein system with
high-grade gold at the surface &
3 distinct target areas with discovery potential

Highland Overview

Large land package: 1,500 hectares, 192 unpatented claims on BLM land
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
Drill-ready project, with Phase 1 RC drill program to commence in July, 2021

West Vein Zone

High-grade gold mineralization at surface in volcanic-hosted epithermal veins

Array of steeply-dipping veins in a NW-trending corridor 1400 m long by 250 m wide
Key alteration features present, including boiling indicators (e.g. quartz-after-calcite)
Headwater to target structural intersections along strike of historic high-grade gold intercepts at depths of 200-300 m
Drill-ready opportunity to expand mineralization footprint north along trend of historic Highland Mine workings

Big Hammer Zone

Strong gold at surface associated with a rhyolite flow-dome and newly recognized graben structures

Historic CORDEX soil survey highlights corridor of gold at surface on flank of rhyolite flow-dome
Silica sinter up to >5 m thick cut by chalcedonic breccia in hanging wall of graben-bounding faults never drill-tested.
35 km of CSMAT across poorly-exposed areas of alteration highlights numerous property-scale structures not previously targeted.
