1. This exploration target is based on the assessment of surface and underground drill data collected by the Company in addition to the significant

amount of historical and archived geological and mine data from over a century of mining activity at Waihi. The exploration target is conceptual

in nature and insufficient exploration has been undertaken in the areas that this exploration target relates to estimate a mineral resource. It is

uncertain if further exploration will result in the estimation of a mineral resource
