Historically, the Scadding Mine produced 914 kilograms of gold from 127,000 tonnes of mineralized material grading 7.2 g/t (OFR 5771).

To date, one (1) hole of the six (6) holes drilled in the deposit's North Zone have been reported. Results indicate that the deposit is made up of thick and stacked zones of high-grade gold mineralization. Hole SM-19-001 intersected 3 separate gold zones (Sept. 26, 2019 News Release):

-- 52.02 g/t gold over 12.3 metres, including 210.23 g/t gold over 3 metres,
