The HALL massive sulphide showing is situated on the south side of Two Mile Creek, approximately 600 metres upstream of Keithley Creek Road on the northwest side of Cariboo Lake and approximately 16 kilometres northeast of the village of Likely.
The showing occurs within the Late Proterozoic to Paleozoic Snowshoe Group, a dominantly siliciclastic package of continental derivation that most likely represents the distal western edge of ancestral North America. This fault-bounded sequence is stratigraphically distinct from other packages around it and as such has been called the Barkerville subterrane, a subset of the Kootenay terrane, with which it shares many similarities. East of the Snowshoe Group, across the west-verging Pleasant Valley thrust, are rocks of the Kaza, Cariboo and Black Stuart groups, which also contain an abundance of siliciclastics, but with facies which suggest a more proximal continental shelf setting. Many of these units can be correlated with similar stratigraphy within ancestral North American rocks. These rocks are placed within the Cariboo subterrane, representing, like the Cassiar terrane to which it belongs, a displaced piece of ancestral North America. The west flank of the Snowshoe Group is occupied by the Quesnel terrane, a composite volcanic-arc sequence dominated by Mesozoic mafic to intermediate volcanic rocks. It is separated from the Snowshoe Group by the east-directed Eureka thrust fault, along which are slivers of mafic and ultramafic rocks assigned to the Crooked amphibolite. This latter package has been correlated with rocks of the Slide Mountain terrane, an assemblage of ocean floor volcanic and sedimentary rocks that structurally straddle the Barkerville and Cariboo terrane lithologies along the Pundata thrust, north of Wells.
Semi-massive to massive sulphide mineralization occurs in outcrops exposed along Two Mile Creek. Sulphides consist mainly of pyrite, pyrrhotite and chalcopyrite. The massive sulphide body exposed at the Hall showing is 2 metres thick, 10 metres wide and undefined along strike and dip directions.
From 1987 to 1988, C.E. Carlson conducted exploration programs on the Duck 1 and Duck 2 claim groups. In 1987, 1179 soil samples were collected from an area 2.5 kilometres north of Rollie (Duck) Creek. The following year, exploration consisted of 127-sample soil geochemistry survey, a 5.48 line-kilometre very low frequency electromagnetic (VLF-EM) geophysical survey and seven diamond drill holes, totalling 1034 metres. Four of the seven drillholes were situated along Two Mile Creek.
Barker Minerals Ltd. began exploration programs in the area in 1999. Most of their early efforts focused on the Frank Creek showings (MINFILEs 093A 152 and 093A 267) to the east on the southeast side of Cariboo Lake. In 2004, the SCR (MINFILE 093A 203), Peacock and Unlikely (MINFILE 093A 163) showings were briefly examined as part of Barker Minerals Ltd.’s Frank Creek exploration program.
From 2004 through 2025, Barker Minerals Ltd. conducted programs of geological mapping, float rock, till, soil and stream sediment sampling across several areas on the Frank Creek (Cariboo Lake) property.
In 2015, rock sample 2485, collected from the south side of Two Mile Creek at the Hall and Peacock (MINFILE 093A 133) showings, assayed 9.32 per cent copper and 0.07 per cent zinc (Assessment Report 36040) and sample 2535 assayed 4.81 per cent copper and 0.03 per cent zinc (Assessment Report 36044). Sample 4585, collected approximately 300 metres northwest of the Hall showing, assayed 12.04 grams per tonne gold (Assessment Report 36044). In 2016, several rock samples collected near the Rollie (MINFILE 093A 336) showing approximately 400 metres downstream of the Hall showing, reported anomalous results for copper, zinc and lead. Sample 4636 assayed 2.11 per cent copper, sample 4703 assayed 1.16 per cent copper, sample 4664 assayed 0.05 per cent zinc and sample 4628 assayed 0.18 per cent lead (Assessment Report 36162).
