The Verona occurrence is located about 9.5 kilometres due south of Alice Arm. The area was prospected for base and precious metals in the early 1920s and mid 1960s.
The region is underlain by Middle Jurassic to Upper Cretaceous Bowser Lake Group argillite, shale, siltstone, greywacke and conglomerate. The sediments are intruded by Lower Tertiary granodiorite and diorite of the Coast Plutonic Complex and have been folded and contact metamorphosed up to biotite hornfels.
The showing comprises a system of quartz-carbonate-barite-sulphide veins which follow shear zones that are developed parallel to bedding in north-northeast striking, west dipping argillite. The veins are cut by porphyritic mafic sills that also follow the shear zones and all are displaced by northwest-trending faults. The vein system strikes 020 degrees for 50 metres and dips 53 degrees west. Primarily, the veins occur as inclusions of variable width and length in a 1.8 to 4.6 metre wide augite-plagioclase-olivine porphyritic andesitic sill. On the north end of the sill, a 0.23 to 0.71 metre wide quartz vein, containing near massive pyrite, pyrrhotite, sphalerite and galena, is exposed for 6.1 metres. A 0.61 metre chip sample taken across the north end of the vein system, likely across the vein with near massive sulphides, assayed 5.8 grams per tonne gold, 283 grams per tonne silver, 10.3 per cent zinc, 8.1 per cent lead and 0.3 per cent cadmium (Property File - Marshall Creek Copper Co. Ltd. Annual Report 1965, page 6).
West of this location, variably sulphidic quartz veins are reported to occur in the hangingwall and footwall of a 0.3 metre wide lamprophyre sill. Mineralization is also reported adjacent to a west striking shear zone, over a width of 0.76 metre, near the south end of this sill.
