2021 historical mineral resource AgEq oz were calculated using 85:1 Ag:Au ratio, and ratios of 1:0.041 and 1:0.049 for the price/ounce of silver to price/pound of lead and zinc, respectively. The ratios are reflective of average metal prices for 2021.
The Topia mineral resource estimate is a historical estimate and the reader is cautioned not to treat them, or any part of them, as a current resource. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves and the Company is not treating the historical estimate as current mineral resources or mineral reserves. The mineral resource is taken from a Great Panther technical report dated March 31, 2021. However, based on the assumptions, parameters and methods in the prior technical report, as well as literature and data review, and the recent site visit conducted for the 2022 Topia technical report, the authors consider such estimate to be relevant and reliable and provides an indication of the extent of mineralization identified by previous operators at the Topia Property. To verify the historical mineral resource estimate as a current mineral resource, a qualified person would need to complete database validation, undertake a full review of estimation parameters and procedures, and complete an updated mineral resource estimate and a NI 43-101 technical report incorporating additional production, drilling and underground sampling completed at Topia since March 31, 2021.
