Brewer In Situ Mineral Resource
Indicated: 202,000 oz Au and 16.8 Mlbs Cu within 6,0 Mt @ 1.04 g/r Au and 0.13% Cu
Inferred: 210,000 oz Au and 7.9 Mlbs Cu within 7.8 Mt @ 0.84 g/t Au and 0.06% Cu
Brewer Backfill Mineral Resource
Inferred: 139,000 oz Au and 9.7 Mlbs Cu within 11.9 Mt @ 0.36 g/t Au and 0.03% Cu
* The Brewer maiden mineral resource estimate was prepared under National Instrument 43-101 (“NI 43-101”) standards by Independent and Qualified Person (QP), Patrick J. Hollenbeck. The Mineral Resource Estimate was constructed using all available drilling information available for the Brewer project, including Carolina Rush core drilling (n = 36); Carolina Rush rotary airblast drilling (n = 194); Historical drilling (n = 1,020); and Historical production blastholes (n = 49,926). The in-situ Brewer Mineral Resources are reported at a 0.5 g/t Au cutoff considered for “reasonable economic extraction” and were calculated using a 3-year gold price (Jan. 2022 – Dec. 2024) of US$2,045/oz and an assumed all-in mining and processing cost of US$33/tonne.
*No grade sensitivity analysis was conducted for the backfill resource model; the reported resource does not apply a cutoff grade as it assumes that all backfill material will need to be removed and processed to support mining of the in-situ resource below the backfill. Details on the metallurgical properties and processing methods required to extract gold and copper from the backfill material have not been undertaken. As such, the Backfill resource is considered theoretical and additional studies are required to report the inferred resources at a higher level of confidence.
