The Sky showing is located 500 metres southwest of Kearsley Creek and 3.5 kilometres southeast of Alouette Lake at an elevation of approximately 1075 metres.
The majority of the region is underlain by granodiorite to diorite intrusions of the Jurassic to Cretaceous Coast Plutonic Complex. Roof pendants of the Paleozoic Twin Island Group and Jurassic Harrison Lake Formation occur throughout the area. These are, locally, intruded by aplite and basaltic dikes.
In the area, mineralization was noted to occur in three distinct modes: 1) quartz-pyrite (± chalcopyrite and magnetite) stringers and veins up to 6 centimetres wide in unaltered quartz diorite, 2) quartz-pyrite lenses up to 0.40 metre wide in unaltered quartz diorite and 3) silicified or calc-silicate altered shear zones up to 3 metres wide containing pyrite and trace chalcopyrite.
Locally, a road-cut exposes a strong shear zone, cutting feldspar porphyry. The porphyry is enclosed in medium- to coarse-grained, altered Late Jurassic quartz diorite of the Coast Plutonic Complex. Mineralization consists of chalcopyrite, pyrite and arsenopyrite in a gangue of banded quartz.
In 1981, a sample (0031) taken across a width of 0.30 metre assayed 0.20 gram per tonne gold, 4.5 grams per tonne silver and 0.98 per cent copper, while another sample (0032) taken over 0.30 metre yielded 0.47 gram per tonne gold and 2.81 grams per tonne silver (Assessment Report 10040, Part 2, page 10).
In 1938, native gold was mined from the Oro occurrence (MINFILE 092GSE041), near the headwaters of Seventynine Creek between Alouette and Stave lakes. Prior to operations closing in 1939, some high-grade shipments were made from the mine. During 1976, the Spanar claims were staked 1500 metres south of Mount Crickmer. An old adit was subsequently relocated and extended approximately 5 metres. An induced polarization survey was also carried out. Between 1981 and 1987, Skyrocket Exploration and Resources Inc. held a large claim block between Stave and Alouette lakes. Exploration revealed spotty gold soil geochemical values; however, later that year a significant gold value was obtained from a major, northeast- trending shear zone. Follow-up sampling and percussion drilling work was done in and around Kearsley Creek in 1984. During 1988 and 1989, soil and rock sampling surveys were carried out on the Oro and Star claims by 007 Precious Metal Inc. In 1995, the area was prospected and sampled as the Crickmer claims. In 2008, the area was sampled and prospected as the Seventy Nine project by Crucible Resources.
