The following has been taken from the Trans-Canada Property 2015 NI 43-101 Report completed by InnovExplo Inc. (K.Brousseau, S.Poirier, C.Pelletier, 2015);
The southern limit of the Property is largely coincident with the Bankfield-Tombill Fault (also called the Bankfield-Tombill Fault Zone, Tombill-Bankfield Deformation Zone and Barton Bay Deformation Zone).
The fault is variably deformed; largely ductile, high strain zone characterized by strong heterogeneous penetrative strain, narrow shear zones and breccia zones cutting a variety of protoliths. Where it is most highly deformed it is described as a “crush zone” by Smyk et al., pg 14, 2005 that “has been intensely silicified (Pye, 1952), Carbonatized (Anglin and Franklin, 1985) and contains minor amounts of gold (Pye, 1952).” Horwood and Pye (1951) describe this fault as a “strongly sheared and brecciated zone, which in Ashmore Township attains a width of 40 feet, strikes N. 77° W. and dips and 70° S.”
South of the Bankfield-Tombill Fault the rock are primarily sediments. The north of the Bankfield-Tombill Fault, the property is dominated by a series of sedimentary units that have an approximate east-west and subvertical orientation. The majority of these units are greywacke, arenite or oxide facies iron formation. Minor conglomerate and argillite rich units are also found. The host unit of the Little Long Lac Mine has historically been referred to as an arkose, but Horwood and Pye (1951) suggested that this unit, although distinctive, would be better termed a quartz greywacke. Individual mm-cm scale bedding is commonly observed in turbidite type sequences within the well bedded units. Massive wacke and arenaceous units are also found. Oxide facies iron formation units (BIF) can vary from cm to decimeter scale in thickness, with mm to cm beds common. Although the BIF units are locally tightly folded, attenuated or boundinaged, individual units can in some cases be traced for hundreds to thousands of metres along strike. The greywacke in the vicinity of the Hard Rock and MacLeod-Coskshutt Mines can contain up to 5% mm-cm scale magnetite beds and has been historically referred to as “Lean Iron Formation” in the mine terminology.
Intrusive rocks include felsic intrusives, notably the Hard Rock Porphyry, diorite, gabbro, and diabase dykes. It is of interest that the Hard Rock Porphyry seems to be sill-like in nature. Even though it is tightly folded and the contacts between it and the sedimentary units are often highly deformed, the general scale and folding pattern of the porphyry very closely matches the geometry of the conglomerate unit that occurs in the vicinity of the Hard Rock and MacLeod Cockshutt Mines.
Deformed quartz and quartz carbonate veins and sulphidised replacement zones occur in BIF host and are spatially related to gold mineralization.
