Garson is a deformed Contact-style deposit. Contact-style mineralized zones are remobilized into a series of near-parallel ductile shear zones. Shear-hosted copper–nickel sulphides are offset by later stage dykes and possible late-stage shearing. The 1 Shear and 4 Shear are the primary mineralized zones.

The 1 Shear extends from surface to below 6500 Level, a distance of approximately 1,980 m. It has a strike length of 120–600 m, with strike length decreasing with depth. Hanging wall to footwall widths along the orebody vary between 3–60 m, with an average width of 10 m.

The 4 Shear extends from the 2800 Level to a currently known limit of 6700 Level, a distance of approximately 1,200 m. It has a strike extent of 685 m and an average width of 7 m. It strikes east– west and generally dips 70° south. The 4 Shear orebody runs parallel to the 1 Shear orebody, lying approximately 45 m to 60 m to the northwest.

Both shears dip at a slightly shallower angles than the SIC contact, which means that above the 4000 Level the shears are mostly hosted in the SIC with the dominant lithology being Sublayer Norite and below the 4000 Level the shears cut the metasedimentary and metavolcanic Huronian footwall rocks.

The deposit is crosscut by two separate olivine diabase dykes. These dykes are sub-parallel to each other and range in width from 15–60 m.

The Garson region was subjected to significantly more structural activity than the ........

The Garson Mine is located immediately northeast of the town of Garson. Garson mine is a part of Vale integrated Ontario Operations which also includes (Coleman, Copper Cliff, Creighton and Totten mines), processing and refining facilities (Clarabelle Mill, Copper Cliff Smelter and Nickel Refinery, Port Colborne refining complex), supported by the Clydach Refinery in Wales, and non-operating mines, and non-producing properties.

The Garson deposit includes the actively mined Garson Surface Ramp (13 and 360), and Garson Mine #1 Shear, #4 Shear deposits. Inactive deposits include the McConnell, and Garson Ramp (600) zones.

The Garson Main Mine is accessed via the 1,293 m (4,240 ft) deep Garson #2 Shaft while the Surface Ramp is accessed through a portal from surface, situated about 400 m west of the shaft collar. The main Level accesses from #2 Shaft are 3800 and 4000. The secondary means of egress for the Main Mine is through is a ladder system in the power raise from surface to 3400 Level. Access. Primary and secondary egresses from the bottom of the Main Mine on 5200 Level to 3400 Level are a combination of haulage declines and relatively short ladderway systems.

The Garson Main Mine and Garson Surface Ramp operations are physically connected on the 200, 400 and 600 Levels. The 200 Level has an escapeway to surface and serves as a secondary means of egress for the Surface Ramp operation. On the 400 Level of the Surface Ramp, access to the Ma ........
