Copperstone Project Pitch

A 2018 Resource Estimate Inferred Resource* 145,700 oz @ 6.81 g/t Indicated Resource* 276,100 oz @ 7.63 g/t Proven & Probable** 175,093 oz @ 6.79 g/t Current Resource model at US$1,250 with higher cut-off than prior resource models Does not capture up to 13,000 meters of successful drilling from 2019 to 2021 Tightly defined mineralized domains which closer fit the geology of deposit Conservative gold grade capping strategy defined by mineralized domains first and by composite second resulting in a much more conservative capping of grades Geology/Structure was used as a constraint for creating domains Classification parameters for M&I were more tightly constrained Blocks are larger and aligned with the dip and strike, however sub-blocking was used to more accurately define volumes and tons Conservative Resource Model with Considerable Upside * National Instrument 43-101 Technical Report dated April 1, 2018: Preliminary Feasibility Study for the Copperstone Project, La Paz County, Arizona, USA ** 0.11 oz/t cut-off, $1,250/oz Au A ARIZONA GOLD CORP 14
