Mandalay Resources Corp (TSE:MND) (OTCMKTS:MNDJF) said Tuesday it has amended and restated mineral resources and reserves estimate for its Costerfield gold-antimony mine in Victoria, Australia.
On January 8, 2018, Toronto-based Mandalay announced an updated mineral reserves and resources estimate for Costerfield, including a maiden Mineral Reserves estimate for the Youle lode.
The company said an error in the block volume transformation methodology affected the modeled vein width of Youle, which led to an understatement of the mineral reserves at Costerfield.
The impact of the amendment on the mineral reserves at Costerfield is a 17% increase in gold ounces and an 11% increase in antimony tonnes.
The company said the error didn’t affect the mineral resource or the mineral reserves for any other vein at Costerfield. The company also said the restated Mineral Reserves do not impact the Mandalay’s previously released 2019-2021 production guidance.
Shares of Mandalay were at C$0.11 on Tuesday.
