Deposit Geology
The Project area, comprising the Kudz Ze Kayah claim blocks within which the ABM deposit is located, encompasses units of the Grass Lakes group. The surface geology of the property was initially mapped by Cominco in 1996 at 1:20,000 scale (Schultz & Hall, 1997) and subsequently by BMC at 1:20,000 scale in 2017 (Baker et al., 2017).

The ABM deposit (comprising the ABM Zone and Krakatoa Zone) primarily comprises continuous, shallowdipping massive sulphide mineralization hosted within a thick felsic package of volcaniclastics and coherent sill/flow complex that locally make up the Kudz Ze Kayah formation.

Massive sulphide of the ABM Zone is hosted within a felsic rock package, whereas the Krakatoa Zone is predominantly hosted by a pre-mineralization mafic sill located within the felsic volcanic package. Mineralization at Krakatoa also occurs in the felsic hangingwall units stratigraphically overlying the mafic sill, in what is broadly interpreted to be the equivalent of the ABM mineralized position. Only scattered vein-style and disseminated mineralization occurs within the mafic sill lying stratigraphically below the ABM Zone.

The upper limits of the ABM and Krakatoa Zones are truncated near surface and overlain by glaciofluvial sediments. The massive sulphide mineralization at ABM occurs under approximately 2– 20 m of glaciofluvial overburden and is up to approximately 30 m in true thickness, whereas the Krakatoa Zone occur ........

Pursuant to the mining plan contained in the Feasibility Study the majority of the ABM Deposit will be mined by open pit mining methods. It is expected that a single pit will be mined, with mining of the ABM Zone comprising four separate stages, and with the Krakatoa Zone mined in a single stage. A total of 14.0 Mt of ore and 138.4 Mt of waste will be mined by open pit mining methods, for an expected average LOM strip ratio of 9.9:1. The Stage One ABM Zone pit has an expected strip ratio of 6:1, in order to facilitate a rapid payback of pre-production capital.

Open Pit Mining
The open pit optimization evaluated several slope sets based on D&S recommendations, but primarily allowing for haul roads to be placed on the hanging wall or the foot wall of the main mineralization.

The Krakatoa pit will be mined as a single stage, as the pit is small and mined near the end of the project life. A portion of the waste material in the Krakatoa pit will be mined early to create a lay down and portal staging area for the planned underground operation. The remainder of the pit is planned to be mined toward the end of the project and concurrently with underground mining.

The ABM Zone dips to the northeast. The deposit, on the surface, is confined by the valley running approximately north to south, and the pit will mine both sides of the valley hills. The main ramp entrance was placed on the north side of the ABM pit, at the lowest point possible, to min ........
