This material takes the inferred resource to 75.9 million tonnes at grades of 4.6% lead, 2.3% zinc, 0.25% copper and 119 g/t silver.
John Lamb, chairman, said: “The revised resource estimate is further evidence of the significant unlocked value of the Bawdwin deposit.”
The material was not included in the maiden estimate completed in October owing to the low grade.
However, an open pit optimisation study by CSA Global indicates that a reduced cut-off grade for lead reflects potential economic extraction.
The study, which is part of a wider scoping study, demonstrates significant potential for a very low cost open pit operation.
“The opportunity to recover additional low-grade material from within the pit shell is compelling as it adds a substantial amount of contained metal into the total resource,” Lamb said.
