NI 43-101 Technical Report Mineral Resource Estimate for the Hyland Go

Briefing

Inferred Mineral Resources must not be included in the economic analysis, production schedules, or estimated mine life in publicly disclosed Pre-Feasibility or Feasibility Studies, or in the Life of Mine plans and cash flow models of developed mines. Key points: Inferred Mineral Resources must not be included in the economic analysis, production schedules, or estimated mine life in publicly disclosed Pre-Feasibility or Feasibility Studies, or in the Life of Mine plans and cash f; The assay results from these trenches established gold mineralization extending over 150 m beyond the extents of the 2016 Main Zone Resource and returned multi-gram gold and silver values over intervals of up to 116 m; Results from the drill program of the 2015 Hyland Gold exploration program include: • Drill hole HY-15-45: 31.08 m of 0.4 g/t gold from 2.45 to 33.53 m including 13.43 m of 0.62 g/t gold from 2.45 to 15.88 m; SGS Geological Services Technical Report – Mineral Resource Estimate, Hyland Gold Project, Yukon Territory, Canada Page 12 Table 1-2 Cost Summary for Recommended Future Work Program Component Units Unit Cost Estimated Co; The trench sample results at Montrose Ridge have low silver response (<1 g/t) like the Cuz Zone, 2.5 km to the north and strengthens the interpretation that both Cuz and Montrose represent a separate or higher- level min; Results included: • 152m of 0.64 g/t Au and 4.93 g/t Ag in TR-18-03 • 42m of 0.90 g/t Au and 6.31 g/t Ag in TR-18-08 All exploration drill core and trench samples from the 2015 Hyland Gold Project were analyzed at Bureau.
