The Spanar showing is located on the east bank of Kearsley Creek, 1.1 kilometres southwest of the peak of Mount Crickmer and at an elevation of 892 metres.
At the Spanar occurrence, a 5.5-metre long trench and a 7.3-metre long adit, striking 160 degrees, were excavated earlier this century. 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.
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.
Several small, quartz-filled shear zones are developed in Late Jurassic quartz diorite of the Coast Plutonic Complex. The shear zones and surrounding quartz diorite are mineralized with pyrite.
In 1977, a chip sample (14631), taken across 0.5 metre, 2 metres south of the portal of the adit, assayed 13.4 grams per tonne gold and 18.3 grams per tonne silver (Assessment Report 6325, page 8). In 1981, a grab sample from the adit portal area assayed 25.3 grams per tonne gold, 20.6 grams per tonne silver and 0.12 per cent copper (Assessment Report 10040). In 1987, a sample, from a 10-centimetre wide shear zone exposed in the north wall of an adit, assayed 56.0 grams per tonne gold, while a diamond drill hole (SK 1) yielded up to 16.8 grams per tonne gold over 2.4 metres (Assessment Report 16604).
