Mineral Resources and Mineral Reserves: Björkdal Gold Mine

RPA, now part of SLR, was retained by Mandalay Resources Corporation to support technical disclosure of Mandalay's 100% interest in the Björkdal Mine and provide annual Mineral Resource and Mineral Reserve (MRMR) Estimates for Björkdal and the adjacent Norrberget Deposit.

Björkdal is operating an open pit mine that has been in production since 1988. Ore processing includes conventional crushing and grinding, followed by a combination of gravity and flotation to recover gold to concentrates which are sold to smelters in Europe. 

Mandalay acquired Björkdal and subsequently completed plant modifications which resulted in increased gold recovery. Mandalay completed a pre-feasibility study for the Norrberget deposit, located four kilometres southeast of Björkdal. The overall mine life as estimated in 2019, including both Björkdal and Norrberget, is nine years producing approximately 518,000 ounces of gold.
