Notes:
1. The Qualified Person for the George, Goose and Llama Mineral Resource estimates is Doug Cater P. Geo, Project Manager Sabina. The Qualified Person for the Umwelt Resource Estimate is Marek Nowak, P.Eng. SRK Consulting (Canada) Inc.
2. Mineral Resources for Goose are estimated at a 1.50 g/t cut-off within an optimised pit shell using a pit discard cut-off grade of 0.70 g/t Au (Goose) and a 0.76 g/t Au ( Llama) and 90% recovery at an average long-term gold price of US$1300 per ounce (Goose) and US$1200 per ounce ( Llama). Pit optimizations were used to constrain the resources.
3. All mineral resource within a 5.00 g/t Au wireframe shell was used to determine the George resource estimate.
4. The Umwelt deposit open pit mineral resources are reported at a cut-off grade of 1.00 g/t. Underground resources are reported at a cut-off grade of 2.00 g/t. cut-off grades are based on a long-term gold price of US$1,360 per ounce and a process recovery of 90%.
5. Numbers may not add due to rounding.
Mineral resources that are not mineral reserves do not have demonstrated economic viability. Mineral resource estimates do not account for mineability, selectivity, mining loss and dilution. These mineral resource estimates include inferred mineral resources that are normally considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is also no certainty that these inferred mineral resources will be converted to measured and indicated categories through further drilling, or into mineral reserves, once economic considerations are applied.
