"These results are encouraging in the context of severe winter conditions and the impact of the [coronavirus] virus on both the copper price and staff movements”, said Pembridge chief executive and chairman Gati Al-Jebouri in a statement.
“Although the quarantine restrictions are affecting operations, they are a necessary measure that should enable the mine to continue operating safely as long as Yukon Government regulations permit this and the safety of all staff working at the mine is not compromised", the CEO added.
