Slide 5: Lewis Project Summary
Lewis Project Summary • The Lewis project is located 8 km northeast of the historic Shortt Lake gold mine (2.7 Mt at 4.59 g/t Au), in a gold district grading on average between 4 and 7 g/t Au (≈800,000 oz). • This is a well-known area, having been the subject of much historical fieldwork since the 1

Lewis 2024 DDH Geochem • 2 DDH in 2024 • Whole rock geochem (n=11) and ICP-MS 4 acids (n=67) done • Study here to identify alteration and metal signatures of the rock types and mineralization 28 28
Slide 29: Lewis 2024 DDH Geochem
Lewis 2024 DDH Geochem • Some samples identified as sedimentary rocks in logs but have Dacites- clear mafic compositions - probable Rhyolites volcanogenic sediments Andesites • All samples would plot as standard tholeiitic basalts (typical flat REE Basalts profiles) based on immobile elements - Prob
Slide 30: Hydrothermal Alteration - WRA
Hydrothermal Alteration - WRA • Sericite alteration index used to identify rocks with potassium changes in the mafic rocks in ICP 4 acids assays • Sericite index < 0.025 indicates K leaching (-50% K2O) • Sericite index indicates K enrichment. K Leaching • 0.18 - 0.35: Sericite = +200% - 500% K2O • 0
Slide 31: Hydrothermal Alteration + Au
Hydrothermal Alteration + Au Albite, K leaching • Higher gold values not particularly associated with Sericite+ high sericite or albite alterations - • Exceptions: the highest albite has 0.1 g/t Au Sericite++ • 0.87 g/t Au et 0.27 g/t Au are sericite alterations with Na leaching (but not the stronge
