early stage project
Selbaie hosts IP anomalies along prospective structures - prime drill targets.
LaSalle's Selbaie Property was acquired by map designation to cover the southeastern contact of the Brouillan Batholith. The property is composed of 14 claims, 100% held by LaSalle in the Northern Abitibi Belt located 12 kilometres east of the old Selbaie Mine.
The Selbaie Cu-Zn-Au-Ag deposit is located within the western pressure shadow of and along the southwest flank of the Brouillan intrusive, a central intrusion/resurgent dome complex. The Selbaie mine was operated by Billiton until 2004 and had a mining resource of 57 Mt composed of VMS type containing approximately 1 Moz Au (not a 43-101 compliant disclosure) considered to represent a sub-type volcanic associated sulphide deposit and epithermal vein and breccia-type mineralization 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.
Compilation work by LaSalle has revealed values of up to 0.2% Cu within a felsic volcanic sequence intruded by a syenite. 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 found during a prospecting effort support the thesis of gold mineralization potential near the sheared intrusive contact oriented northeast.
Drill targets will primarily focus on IP anomalies along interpreted northeast and northwest structures as the ones controlling the B-14 mineralization 700 m south of our property. In 2013, Excellon reported visible gold and drilling results within the B14 Zone of:
5.43 g/t Au over 8.00 m (4.12 g/t cut to 34 g/t) and 5.49 g/t Au over 5.07 m (3.28 g/t cut to 34 g/t) in BE13-042;
3.03 g/t Au over 11.10 m in BE13-045, including 4.25 g/t Au over 6.00 m;
45.9 g/t Au over 6.83 m, including 224 g/t Au over 1.23 m in BE13-038
In March 2019 Wallbridge reinforced these values while reporting a drill intersection of 2.55 g/t gold over 20 metres.
