The Angel showing is located on a gentle southwest-facing slope, near the Texada Forest Service Road on Texada Island, approximately 20 kilometres southeast of Gillies Bay.
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 occurrence 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.
Several structural features are evident. A wide shear zone trends 120 degrees with related shears at 120 to 130 degrees. A major set of crosscutting lineaments strike 090 to 110 degrees. Rocks adjacent to major shears are often strongly foliated, sheared, jointed, altered and occasionally mineralized.
Locally, chloritic alteration is common in basalts in the Angel occurrence area. Carbonatization (ankerite) is evident along faults or fractures and near limestone. Epidote is pervasive and occurs most often as stringers with or without quartz, or as fracture fillings. Hematite is most evident with manganese staining in sheared basalt and is accompanied by coarse pyrite and quartz-pyrite mineralization. Silicification occurs as several distinct types. The first is a microscopic silica flood as blebs and veinlets of quartz found over wide areas, usually in the vicinity of major structural features. More intense silica flooding is seen in strongly foliated rocks or within fragments of silicified volcanics in areas of quartz-carbonate breccia. Very late-stage quartz veining crosscuts all earlier types of alteration and mineralization.
The Angel occurrence is a limonite/silicified basalt breccia with irregular patches of more intense silicification and quartz flooding containing disseminated pyrite. This alteration assemblage is crosscut by quartz veins with traces of malachite and chalcopyrite and a fine fracture coating of carbonate with sparse malachite stain. Areas of unaltered basalt occur within the shear zone and in adjacent outcrops. Shearing is observed at an average orientation of 150 degrees; several subparallel shears also occur. Mineralization appears to cross this trend at 115 to 130 degrees. The mineralized zones lie within one broad shear zone and are not continuous but more likely form an anastomosing network of shear structures.
Work History
The Angel occurrence was discovered in 1985. The same year, Caribou Gold Corp. optioned the ground and did a limited soil and geological survey. They also drilled a single long-core hole, totalling 137.16 metres. Highlights include a 1.0-metre section of drillcore (25.50 to 26.50 metres down hole) that averaged 16.36 grams per tonne gold with other intercepts yielded from 0.50 to 3.20 grams per tonne gold over 0.5- to 1.0-metre sections from 31.23 to 83.50 metres down hole (Assessment Report 14916). Also at this time, surface samples yielded values of up to 10.90 grams per tonne gold (Sample JS-A-3; Assessment Report 14916).
In 1987, a program of prospecting, minor test pitting and trenching and geochemical (rock and soil) sampling was conducted on the area immediately southeast as the Bobs, Cisco, Ed, Jen and May claims. A rock sample (ED-1R) taken from a pit on an area of quartz stockworks hosting pyrite, located approximately 500 metres to the southeast and near the junction of the Ed 1-2 and Angel claims, yielded 0.88 gram per tonne gold (Assessment Report 16013).
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 Angel claims. A rock sample (S2444) from the main showing yielded 8.72 grams per tonne gold (Assessment Report 17685). Later that year, channel sampling of trenches yielded values of up to 15.92 grams per tonne gold over 1.3 metres from trench 1 and 5.25 and 3.67 grams per tonne gold over 0.6 and 1.0 metre, respectively, in trench 2 (Assessment Report 18671). Also at this time, rock samples, taken approximately 400 to 700 metres along strike to the east-southeast, from areas of variably carbonate-limonite-epidote–altered basalt with quartz veins and chalcopyrite mineralization, yielded values of up to 0.71 per cent copper and 37.2 grams per tonne silver (Sample XR2503; Assessment Report 18671).
In 1989, Nexus Resource Corp. optioned the Angel property from Rhyolite Resources Inc. and completed a program of prospecting, geological mapping, geochemical (rock, silt and soil) sampling, an induced polarization-resistivity survey and 540 metres of diamond drilling in five drillholes on the Angel and Fox claim groups. The drillholes intersected from 7 to 14 main, narrow intervals with anomalous to highly anomalous gold values within a 50- to 95-metre wide portion of the Angel fault zone. Three holes intersected two, non-correlative intervals with higher gold, spaced 10- to 65-metres apart. These range from 10.80 grams per tonne gold over 0.15 metre in hole 89-1, through 3.53 grams per tonne gold over 0.48 metre in hole 89-4, to 2.05 grams per tonne gold over 1.88 metres in hole 89-3 (Assessment Report 19509). Also at this time, chip sampling of trench 7 yielded 2.33 grams per tonne gold over 1.5 metres from a newly identified gold-bearing zone in the trench (Assessment Report 19509).
In 2000, Northstar Mining Ltd. acquired the property encompassing the Angel showing. In 2001, the company completed an intensive geological mapping program. In 2007, Northstar Mining Ltd. conducted a 2257.6-hectare remote sensing (spectral analysis) program on the area as the Dude-Tak properties. The following year, a prospecting program and a 500.0-hectare remote sensing (gamma-ray) survey was conducted. In 2009, a further 167.0-hectare remote sensing (spectral analysis) survey was conducted on the area immediately northwest as the Tak 2 claim.
In 2013, Northstar Mining Ltd. conducted a minor program of geological mapping and rock sampling on the area as the Texada property. A select rock sample (E5123092) of quartz-carbonate-sulphide stringers from a historical trench assayed 2.54 grams per tonne gold (Assessment Report 33754). Also at this time, 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.
In 2019, Quadra Coastal Resources Ltd. conducted a geological mapping program on the area as the Angel Gold 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. In 2022, a rock sample (62288) from the Angel occurrence assayed 1.28 grams per tonne gold (Assessment Report 40479). In 2024, rock sample (84267) from quartz diorite at a contact with basalt hosting quartz veins with trace pyrite, located approximately 450 metres to the east-southeast of the occurrence assayed 4.9 grams per tonne silver and 0.38 per cent copper (Assessment Report 42630).
