The Nightfly occurrence is located on a ridge south of Menard Creek and west of the Ingenika River, approximately 153 kilometres north-northwest of the community of Germansen Landing.

The regional and local geology is similar to that of the ARD occurrence (MINFILE 094D 090) located 1.7 kilometres northwest.

Locally, the area is cut by a north-trending fault that separates andesitic rocks of the Upper Triassic Savage Mountain Formation (Takla Group) to the west, from an undifferentiated package of Upper Triassic volcanics (Takla Group) to the east. Both volcanic packages are represented by aphanitic to porphyritic (feldspar) andesites. The undifferentiated volcanics are cut by medium-grained gabbro with phenocrysts of plagioclase feldspar and pyroxene.

The Savage Mountain volcanics are cut by northwest trending, pink porphyritic granodiorite dikes. These dikes contain hornblende and plagioclase phenocrysts in a matrix of quartz, plagioclase and orthoclase.

Copper mineralization with associated pyrite occurs near the fault.

In 2015, mineralization was identified as predominantly secondary copper mineralization (malachite) within epidote altered volcanics with mineralization localized to narrow shear zones and within localized gossans. Localized pyrite and chalcopyrite as disseminations and veinlets was also identified. Several narrow diorite dikes were located with common gossan developing at contact with Takla volcanics. Best results from sampling include 3.04 per cent copper from rock sample R203480 from a strongly epidote altered shear zone within volcanics hosting quartz-calcite stringer veinlets and 1-2 centimetre chalcopyrite veins with secondary malachite and azurite (Assessment Report 35565).

Work History

In 1973, Denison Mines Ltd. completed a program of geological mapping, soil sampling and a 21.0 line-kilometre ground magnetic survey on the area Ard claim group.

In 2015, High Power Exploration conducted property wide, broadly spaced geochemical sampling and reconnaissance style mapping and prospecting on key target areas on their large Menard property which covers eight occurrences (ARD, 094D 090); Kim, 094D 174; Overstall, 094D 154; Verna, 094D 173; Menard Pass, 094D 049; Garry, 094D 175; Nightfly (this description); and Nikos, 094D 085. A total of 10 days field work were completed and included the collection of 78 stream silt sediment samples of first and second order creeks across the property, the collection of 202 “B” horizon samples on topographic contour lines on approximately 100 metre-spaced samples in areas with outcrop or thin cover, and the collection of 294 "Ah" horizon soil samples on topographic contour lines with 100 metre-spaced samples in areas with thick till cover. Several recorded MINFILE occurrences and key target areas were prospected. A total of 59 rock chip samples were also collected during prospecting traverses.

In 2021, Wedgemount Resources Corp. completed a program of geochemical (rock and soil) sampling and spectral analysis on the area as the regionally extensive Cookie property.
