The Summit Nunatak area is underlain by andesitic rocks of the Lower Jurassic Unuk River Formation, Hazelton Group. The strata are intruded by granodioritic rock of the Early Jurassic Texas Creek Plutonic Suite.

The Nunatak showing occurs where the northwest trending quartz-sercite-pyrite alteration zone intersects northeast trending fault structures which contain significant base and precious metal bearing sulphide mineralization. Two areas of detailed mapping and sampling in the 1990s occurred at the Glacier Edge (104B 650) and Nunatak zones which are both exposed at 1550 metres elevation. Geological mapping shows a dominant northwest trend for fracturing and faulting with a sulphide enriched northeast trend that is localized near the major northeast trending structures. Typical sulphide mineralization occurs as pods and lenses of massive pyrrhotite (10 to 50 per cent) with minor amounts of sphalerite, chalcopyrite, arsenopyrite and galena hosted in indurated and hornfels, chlorite and carbonate-altered tuffs/flows.

A 1.3 metre chip sample containing 30 per cent pyrrhotite, trace chlorite and traces of chalcopyrite assayed 0.09 per cent copper, 0.01 per cent lead, 0.01 per cent zinc, 7.0 grams per tonne silver and 3.78 grams per tonne gold (Assessment Report 25677).

In 1998 Fundamental Resources collected 19 rock chip samples, 1 soil sample and conducted 1.4 kilometres of magnetometer surveying.

In 2012, Eilat Resources Inc completed an airborne magnetic survey on their Summit Lake property. The survey, carried out, covered a total of 332.5-line kilometres. It was flown at 150 metre line spacing in a north-south flight direction.

In 2016, Triangle Exploration Limited (optionee from Eilat Explorations) completed a 566-kilometre airborne magnetic and radiometric survey which extends east, north and south from the eastern shore of Summit Lake to the eastern boundary of Eilat Exploration's 2012 airborne survey. The 2016 survey is a continuation of the airborne survey flown for Eilat Exploration in 2012 (Assessment Report 33511). Data collected from the 2016 Summit Lake survey block were merged with data collected in 2012 (Assessment Report 36318). The combined data covers 10 mineral occurrences documented in MINFILE: Scottie Gold (104B 034), St. Eugene (104B 036), Scottie North (104B 074), Blueberry (104B 133), Hicks (104B 139), Summit 5 (104B 436), Summit Gossan (104B 648), Summit Nunatak (104B 649), Glacier Edge (104B 650).

During 2018 through 2020, Scottie Resources Corp. completed programs of rock and auger (tailings) sampling, airborne and ground geophysical surveys and diamond drilling on the Scottie Gold property.
