The Bay 5 (Angel 4) occurrence is located at an elevation of approximately 600 metres on the southwest slope of Mount Grant and approximately 600 metres west of the summit.
Regionally, the area is underlain by undivided sedimentary rocks of the Mississippian to Lower Permian Nanoose Complex (Buttle Lake Group), limestone, marble and calcareous sedimentary rocks of the Middle to Upper Triassic Quatsino Formation (Vancouver Group) and basaltic volcanics of the Upper Triassic Karmutsen Formation (Vancouver Group). The sedimentary and volcanic rocks have been intruded by granodioritic rocks of the Early to Middle Jurassic Island Plutonic Suite.
Locally, a vesicular or amygdaloidal basalt hosts bornite and chalcopyrite mineralization in fractures. Another zone of mineralization, located approximately 450 metres to the north-northwest, comprises chalcopyrite mineralization is reported in an area of sheared and limonitic basalts and diabase dikes.
In 1988, a rock sample (XR32324) from the first zone of mineralization assayed 1.26 grams per tonne gold, 15.2 grams per tonne silver, 2.05 per cent copper, while two rock samples (XR32325 and XR32326) from the second zone assayed 0.75 and trace zinc, 0.59 and 1.89 per cent copper, 16.1 and 8.9 grams per tonne silver, respectively (Assessment Report 18671).
In 2023, a rock sample (62333), located approximately 300 metres to the northwest, assayed 0.20 per cent copper (Assessment Report 41233).
Work History
In 1988, Echo Bay Mines entered into a joint venture with Rhyolite Resources Inc. who then completed a program of prospecting, geological mapping, trenching and geochemical (rock, silt, soil and heavy mineral) sampling on the area as the Angel 4 and Bay 5 claims of the Angel property.
In 2013, Northstar Mining Ltd. conducted a 19 000-hectare remote sensing (spectral analysis) survey on the area as part of the regionally extensive Texada Island property.
During 2022 through 2024 Quadra Coastal Resources Ltd. conducted programs of prospecting, geochemical (rock and soil) sampling, LIDAR data reprocessing and a total of 553.2 line-kilometres of airborne magnetic surveys on the Texada Island property.
