Kwanika Central (Open Pit and Underground) Notes

• The Mineral Resources have been compiled by Mr. Brian S. Hartman, M.S., P.Geo., Ridge Geoscience LLC, and subcontractor to Mining Plus. Mr. Hartman is a Registered Member of the Society for Mining, Metallurgy & Exploration, and a Practicing Member with Professional Geoscientists Ontario. Mr. Hartman has sufficient experience that is relevant to the style of mineralization and type of deposit under consideration and to the activity that he has undertaken to qualify as a Qualified Person as defined by NI 43-101.
• The Mineral Resource estimate has an effective date of January 4, 2023.
• Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
• The totals contained in the above table have been rounded. Rounding may cause some computational discrepancies.
• Mineral Resources are estimated consistent with CIM Definition Standards and reported in accordance with NI 43-101.
• Open Pit Mineral Resources are reported on an in-situ basis at an NSR of US$8.21 and constrained by an economic pit shell. Underground Mineral Resources are reported at an economic cut-off of US$16.41 and constrained by a conceptual block cave shape. Cut-offs are based on assumed prices of US$3.50/lb for copper, US$21.50/oz for silver, and US$1,650/oz for gold. Assumed metallurgical recoveries are based on a set of recovery equations derived from recent metallurgical test work. Maximum recoveries were limited to 95% for Cu, 85% for Au and 72% for Ag. Milling plus G&A costs were assumed to be US$8.21/tonne, and underground mining and G&A costs are assumed to be US$8.20/tonne.
• Actual SG measurements were interpolated into the block model, with an average SG of 2.74.
• The quantity and grade of reported Inferred Mineral Resources in the 2023 PEA are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral Resources as Indicated or However, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
• The estimate of Mineral Resources may be materially affected by geology, environment, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.

Stardust (Underground) Notes

• The Mineral Resources have been compiled by Mr. B Ronald G. Simpson of GeoSim Services Inc. Mr. Simpson has sufficient experience that is relevant to the style of mineralization and type of deposit under consideration and to the activity that he has undertaken to qualify as a Qualified Person as defined by NI 43-101.
• The Mineral Resource estimate has an effective date of January 4, 2023.
• Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
• The totals contained in the above table have been rounded. Rounding may cause some computational discrepancies.
• Mineral Resources are estimated consistent with CIM Definition Standards and reported in accordance with NI 43-101.
• Reasonable prospects for economic extraction were determined by applying a minimum mining width of 2.0 meter and excluding isolated blocks and clusters of blocks that would likely not be mineable.
• The base case cut-off of US$88/t was determined based on metal prices of $1,650/oz gold. $21.50/oz silver and $3.50/lb copper, underground mining cost of US$64/t, transportation cost of US$6/t, processing cost of US$8.25/t, and G&A cost of US$9.75/t. Recovery formulas were based on recent metallurgical test results. Maximum recoveries were limited to 95% for Cu, 85% for Au and 72% for Ag.
• Block tonnes were estimated using a density of 3.4 g/cm3 for mineralized material.
• Six separate mineral domains models were used to constrain the estimate. Minimum width used for the wireframe models was 1.5 m.
• For grade estimation, 2.0-meter composites were created within the zone boundaries using the best-fit method.
• Capping values on composites were used to limit the impact of outliers. For Zone 102, gold was capped at 15 g/t, silver at 140 g/t and copper at 7.5%. For all other zones, gold was capped at 6 g/t, silver at 140 g/t and copper at 5%.
• Grades were estimated using the inverse distance cubed method. Dynamic anisotropy was applied using trend surfaces from the vein models. A minimum of 3 and maximum of 12 composites were required for block grade estimation.
• Blocks were classified based on drill spacing. Blocks falling within a drill spacing of 30m within Zones 2, 3, and 6 were initially assigned to the Indicated category. All other estimated blocks within a maximum search distance of 100 m were assigned to the Inferred category. Blocks were reclassified to eliminate isolated Indicated resources within inferred resources.
• The quantity and grade of reported Inferred Mineral Resources in the 2023 PEA are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral Resources as Indicated or However, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
