In August of 2021, Golden Predator Mining Corp. merged with Arizona Gold Corp. to form Sabre Gold Mines Corp. The Brewery Creek project is 100% owned by Golden Predator Exploration Ltd., a wholly owned subsidiary of Sabre Gold Mines.

Summary:
The Brewery Creek deposits exhibit characteristics of both intrusion-related and epithermal type deposits. It is generally considered to be an alkalic intrusion-associated, gold deposit as most of the mineralization is concentrated within or proximal to the monzonites. Geological, geochemical, petrographic and fluid inclusion data indicates that original sill emplacement, first stage alteration and associated mineralization occurred at a relatively low temperature and high level within the crust. However, the presence of wispy-textured quartz veinlets, related to later shear zone deformation, indicates deposition at moderate to deep levels (Dunne, 1995), a common characteristic of epithermal type deposits (Poulsen,1996).
Historical production on the property occurred along the historical BCRT. The Brewery Creek District consists of numerous deposits, mineralized zones and past producing deposits both along this trend as well as within peripheral mineralized areas. Past producing areas within the BCRT include the Pacific, Blue, Canadian, Upper Fosters, and Kokanee, Golden and Lucky deposits. Additional to these, Mineral Resources have been defined for the Big Rock West, Big Rock East, Lower Fosters, Bohemian and Schooner deposits along the BCRT; the North Slope deposit north of the BCRT; Sleeman deposit east of the BCRT, and the Classic and Lone Star deposits south of the BCRT. Mineralized areas peripheral to the BCRT, including Moosehead, have not been considered f ........

Mining Methods

- Backfill
Summary:
An open pit method is the most appropriate mining method for the estimated mineralized material, which is primarily oxide and shallow in nature. Deeper material that is potentially sulfide material could be considered in the future through alternate mining methods. The Vulcan pit optimizer was used to create Lerchs-Grossmann shells of the economic mineralized material to be utilized in the open pit mine designs. The designs are triple benched at a height of 6 meters, for a total height of 18 meters. The catch bench width is 8 meters.
Preliminary designs were carried out in Maptek Vulcan software. The designs use a bench face angle of 65 degrees, a catch bench width of 8 meters, and a bench height of 6 meters that is triple benched to a height of 18 meters.
Pit Designs
The optimized pit shells and the re-blocked Resource block model were used as a basis for preliminary Life of Mine (LOM) open pit mine designs. Pit design work was completed using Vulcan software. Ramps were limited at 12% grade for in-pit haulage. In-pit haul roads were designed for single-lane traffic, while two-lane traffic was planned for haulage outside of the pits.
Drilling and Blasting
Primary fragmentation for mining will be carried out using traditional drill and blast techniques common in open pit mining. For the purposes of this study, a powder factor of 0.5 kg/m3 was used for both mineralized material and waste rock.
Drilling will be conducted ........

Reserves at January 18, 2022:
For all resource areas the cut-off grade used is 0.37 g/t Au. This cutoff grade corresponds to a gold price of $1,500/oz and processing cost of $12.43 per tonne and an overall recovery of 70% of the in-situ metal.
