The Dave’s occurrence is located at an elevation of approximately 600 metres on a northeast-facing slope on southern Texada Island and approximately 2.4 kilometres southeast of Mount Grant.
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.
The area is predominantly underlain by basaltic volcanic rocks of the Upper Triassic Karmutsen Formation (Vancouver Group). The basalts range from feldspar porphyritic to augite porphyritic with amygdaloidal and aphanitic varieties also present. Pillow basalt flows are common. Limestone occurs locally as narrow lenses with limited lateral extent. The Karmutsen Formation volcanics are in contact with a diorite intrusive. The contact area is silicified and contains pyrite as fracture fillings and disseminations. Hematite and minor epidote are also evident.
Locally, a narrow, 0.3-metre wide, pyritic quartz vein of limited extent striking 072 degrees and dipping steeply south, cuts an altered intermediate dike that has been sheared in a direction parallel to the vein. The dike in turn crosses the diorite intrusive. A weathered pyritic quartz porphyry dike occurs 30 metres along strike from the vein and is cut by carbonate stringers and a 0.5- to 1-metre wide, strongly silicified and limonitic shear zone.
In 1988, a rock sample (XR32356) from the quartz vein assayed 14.83 grams per tonne gold (17.42 grams per tonne gold on re-assay) and 42.4 grams per tonne silver, whereas a nearby sample chip sample (XR32351) yielded 0.17 gram per tonne gold, 38.4 grams per tonne silver and 0.108 per cent tungsten over 0.6 metre (Assessment Report 18671). A 0.6-metre-long channel sample from a trench yielded 5.93 grams per tonne gold (Assessment Report 18671).
Also at this time, a rock sample (XR32302), taken approximately 1 kilometre to the northwest, assayed 0.56 per cent copper, 4.9 grams per tonne silver and 0.08 gram per tonne gold, and another rock sample (XR32811) taken from a creek canyon, located approximately 700 metres to the northeast, exposing mylonized feldspar phyric basalt and diabase dikes yielded 0.64 gram per tonne gold and 0.26 per cent copper (Assessment Report 18671).
In 2022, a grab sample (1531500) of sheared basalt hosting pyrite veins, located approximately 100 metres south of the plotted location of the occurrence, assayed 0.379 gram per tonne gold and 0.551 per cent copper (Assessment Report 40479).
In 2023, two grab samples (62326 and 62327) of chloritic basalt hosting quartz-carbonate veins with pyrite, located approximately 500 metres to the west of the plotted location of the occurrence, yielded values up to 0.29 gram per tonne gold and 0.25 per cent copper, and another grab sample (62393) from a dacite hosting a pyrite vein, located a further 400 metres west-southwest, assayed 0.49 gram per tonne gold (Assessment Report 41233).
In 2024, a grab sample (84241) from rhyolite hosting arsenopyrite, pyrite and trace chalcopyrite and galena mineralization, located approximately 900 metres to the west-southwest, assayed 0.73 per cent lead, 8.91 grams per tonne silver and 0.343 grams per tonne gold (Assessment Report 42630).
Work History
In 1985, Cariboo Gold Corp. conducted a program of rock and soil sampling on the area as the Long B claims. 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 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. In 2014 and 2015, Northstar Mining Ltd. conducted a geological interpretation program to identify future target areas for exploration on the 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.
