The updated mineral resource encompasses 507,238 metres of drilling in 2,205 holes, including 39,208 metres in 209 holes drilled from March to December 2021.
Most of the drilling was dedicated to infill drilling to convert inferred resources from the preliminary economic assessment (PEA) to indicated resources, which together with the recently completed and reported metallurgical testwork results will be used as a resource base for the upcoming pre-feasibility study (PFS).
The completed drilling converted inferred resources from the PEA to indicated resources, with a conversion rate greater than 100%. In particular, the Kierens-Norlartic open pit M&I resources more than doubled from the 2020 estimate. Those in the M&I category now account for 91% of the Marban resource estimate.
Pre-feasibility study expected this year
“We are very pleased with the Marban resource update, which successfully converted our inferred resources into…
