The Hecla showing is located on the southwestern slopes of Mount Jardine, Blue Ridge area, 20 kilometres northwest of Kaslo, British Columbia.

Silver-lead-zinc mineralization occurs in the Triassic Slocan Group, locally consisting primarily of black fissile phyllites with interbedded limestone, calcareous phyllites and brown gritty quartzites. The general structural trend is 310 degrees, dipping generally southwesterly. Greenstones and ultramafic rocks of the Permian Kaslo Group unconformably underlie the Slocan Group to the east, also hosting silver-lead-zinc mineralization. Satellite stocks, dikes and sills are generally correlative with the Nelson batholith to the immediate south. Late stage lamprophyre dikes are also common.

The showing consists of a crystalline quartz-carbonate vein hosted in a narrow, vein-bearing fissure. The fissure has a strike of 028 degrees and a vertical dip. It has been traced northward (uphill) some 30 metres. The vein width varies from 3 to 5 or more centimetres with galena streaks up to 10 centimetres in width. Sparse iron-bearing carbonates within the vein are limonite altered. The vein is hosted in tuffaceous sediments and greenstones of the Kaslo Group.

No assay values are reported from this vein and subsequent property work in 1969 consisted of a geochemical soil survey.
