Selbaie Location MapLocation: 32E/15, Beschefer Township

Ownership: 14 claims owned 100% by LaSalle totalling 778 hectares

Target: Intrusion related gold (+ copper) 

Highlights: LaSalle's Selbaie Property was acquired by map designation to cover the virtually unexplored southeastern part of the Brouillan Intrusive Complex and is targeting a Selbaie deposit analog.

The Selbaie Cu-Zn-Au-Ag deposit is located within the western pressure shadow of and along the SW flank of the Brouillan Intrusive, a central intrusion/resurgent dome complex and is considered to represent a new sub-type volcanic associated sulphide deposit. Selbaie mine had a mining resource of 57 Mt composed of VMS type and epithermal vein and breccia-type mineralisation associated with strong potassic alteration (porphyry Cu style). It has been postulated that the deposit was formed within a large caldera structure over the Brouillan Batholith. Regional work has identified that the Brouillan Batholith is in fact a complex of intrusive events including mafic gabbroic rock to granodiorite/tonalite flanked by volcanic sequences. Past exploration for Selbaie-type deposits have all focused on the Brouillan volcanic sequence south of the Batholith. The Intrusive Complex is the Selbaie analog target and little exploration was done in the eastern pressure shadow of the Complex. Compilation work by LaSalle has identified the presence of felsic volcanic sequences within what has been interpreted as being the Brouillan Intrusive Complex and values of up to 0.2% Cu and minor zinc mineralisation within the felsic sequences are reported. Prospecting in this target area is hampered by areas of extensive overburden cover however two significant outcrops were uncovered and shown here below. A strongly altered granodiorite with strong quartz veining and a breccia body hosting iron carbonate fragments support LaSalle's exploration thesis. LaSalle's exploration program includes a detailed airborne magnetic and electromagnetic survey followed by ground prospecting, till sampling and ground IP to define drill targets.
