The disclosure below is from the technical report dated March 7, 2024 (effective date December 31, 2023) titled “Technical Report on the Valenciana Mine Complex, Guanajuato, Mexico” available on SEDAR+ (the “VMC Report”).
On February 28, 2022, Great Panther reported a Mineral Resource Estimate (“MRE”) for the VMC. The MRE is supported by a technical report titled, “NI 43-101 Mineral Resource Update Technical Report on the Guanajuato Mine Complex, Guanajuato and San Ignacio Operations, Guanajuato State, Mexico”, prepared for Great Panther by Brown and Nourpour (2022), with an effective date of July 31, 2021.
The 2021 Great Panther MRE are “historical resources” and the reader is cautioned not to treat them, or any part of them, as a current resource. Based on this information, as well as literature and data review, and the recent site visit conducted for this VMC Report, the author of the VMC Report considers the 2021 Great Panther Estimate to be relevant and reliable. The resource was prepared by a reputable company that is intimately familiar with, and knowledgeable about, the VMC Property, as well as the geology and resource potential of the VMC Property. The historical resource provides an indication of the extent of mineralization identified by previous operators at the VMC. To verify the historical MRE 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 NI 43-101 technical report incorporating additional production (mining depletion), drilling and underground sampling completed at the VMC since July 31, 2021.

Notes:
1. Cut-offs were based on the marginal operating costs per mining area being USD$135.70/tonne for Cata, USD$135.70/tonne for Santa Margarita, USD$96.50/tonne for Los Pozos, USD$124.90/tonne for Guanajuatito, USD$148.50/tonne for Promontorio, and USD$113.10/tonne for Valenciana.
2. Block model grades converted to USD$ value using plant recoveries of 87.15% Ag, 86.70% Au, and net smelter terms negotiated for concentrates.
3. Rock Density for Cata is 2.66t/m³, 2.65t/m³ Santa Margarita, Los Pozos 2.68t/m³, Guanajuato 2.69t/m³, Promontorio and Valenciana 2.67t/m³.
4. Totals may not agree due to rounding.
5. Grades in metric units.
6. Contained silver and gold in troy ounces.
7. Minimum true width 0.5m.
8. Metal Prices USD$20.00/oz silver, and USD$1,650.00/oz gold.
9. AgEq oz were calculated using 85:1 Ag:Au ratio.
The historical MRE was classified using the definitions set out in the CIM Definition Standards (May 2014). Geological modelling and subsequent Mineral Resource estimation were performed by Great Panther under the supervision of a QP in accordance with the CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (November 2019). A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves; and the issuer is not treating the historical estimate as current mineral resources or mineral reserves.
