All four holes drilled to date as part of the 2021 drilling program have intersected mineralized structures below the current workings of the mine, which are only 350 metres below the portal. Assays for the remaining three holes are pending.
Approximately 1,000 metres of drilling is planned for the current quarter. This program was originally initiated in March 2020 but suspended due to covid-19 after the completion of 831 metres of drilling.
“We are extremely pleased with the initial results from this year’s drill program. Not only have we intersected high-grade copper mineralization below our current workings, but the silver and gold values appear to be increasing at depth relative to our current NI 43-101 mineral resource,” Ian Berzins, president and CEO, commented in a news release.
The company plans to follow-up on the results of the 2020 drilling program and on several historical diamond drill holes that are located below the current workings.
One historical drill hole located below and to the east of the current resource model of the Main South vein yielded a composite average of 2.86% Cu over 9.9 metres, including 4.27% Cu over 6.0 metres. A second historical drill hole yielded a composite average of 3.21% Cu, 21.29 g/t Ag and 1.18 g/t Au over 4.15 metres.
Bull River is an underground operation hosting copper, gold and silver mineralization that was in production in the early 1970s.
The project currently has 1.51 million tonnes of copper, gold and silver mineralized material in indicated resources with an average copper equivalent grade of 2.263% CuEq.
