The Falcon A2 showing is located on the west side of a north-facing cirque, 3.0 kilometres south of Mount Gordonia and 6.5 kilometres north of the confluence of McClair Creek and the Toodoggone River (Assessment Report 19097). The showing is 300 kilometres north of Smithers. It lies within the Omineca-Cassiar mountains in the north-central portion of the Toodoggone gold camp.
The Falcon A2 showing is situated within a Mesozoic volcanic arc assemblage which lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.
Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. These Takla rocks have been intruded by plutons and other bodies of the mainly granodiorite to quartz monzonite Early Jurassic Black Lake Suite and are in turn unconformably overlain by or faulted against Lower Jurassic calcalkaline volcanics of the Toodoggone Formation, Hazelton Group.
The dominant structures in the area are steeply dipping faults which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.
The Falcon A2 showing is underlain by felsic to intermediate Toodoggone volcanics. An Early Jurassic granodiorite to quartz diorite stock lies immediately to the south and southwest. The volcanics are gently south dipping and consist of dacitic porphyritic flows and lapilli and crystal lapilli tuffs (Assessment Report 19097). These have been mapped by Diakow as undivided Toodoggone volcanics consisting of welded lapilli tuff and pyroclastic breccia, rare accretionary lapilli tuff, porphyritic andesite and subordinate basalt lava flows, interspersed volcanic conglomerate, and laminated siltstone and mudstone (Bulletin 86).
The Falcon A2 showing consists of a system of quartz veining and silicification within limonite-altered andesite containing galena and chalcopyrite, traceable over 150 metres in float and outcrop. Weakly altered andesite with local chalcocite and malachite concentrated in fractures occurs 250 metres to the south-southwest near a small pond.
In 1986, 12 of 15 samples from the main zone yielded from 0.07 to 0.45 per cent copper, 0.01 to 3.90 per cent lead, 0.01 to 16.20 per cent zinc, 1.9 to 20.0 grams per tonne silver and trace to 1.00 gram per tonne gold, and three samples taken from a 0.9 metre wide quartz vein with chalcopyrite, located near a small pond to the south-southwest, assayed yielded from 2.71 to 2.72 per cent copper, 103.5 to 118.2 grams per tonne silver and 0.78 to 1.05 grams per tonne gold (Property File – Carter, N. [1987-09-30]: Peregrine and Falcon A Property - Toodoggone River area).
In 1989, a grab sample (PD-89-25) of altered andesite with local quartz veining hosting galena and minor chalcopyrite assayed from the main trenched zone yielded 0.018 gram per tonne gold, 6.8 grams per tonne silver, 0.12 per cent copper, 1.60 per cent lead and 1.14 per cent zinc, whereas a sample (FR-89-57) of aplite with quartz veinlets and local chalcopyrite taken from a second zone of trenching, located approximately 200 metres to the north, yielded 0.445 per cent copper (Assessment Report 19097).
Also at this time, two samples (PD-89-46 and -47) of andesite with malachite and chalcocite, taken near a small pond located approximately 320 metres to the south-southwest, yielded 0.309 and 0.828 gram per tonne gold, 30.7 and 55.5 grams per tonne silver with 0.615 and 1.080 per cent copper (Assessment Report 19097). A sample (FR-19-48) from a quartz vein located at an elevation of approximately 1800 metres on a north-south–trending ridge, approximately 1.1 kilometres to the west-northwest, assayed 22.4 grams per tonne silver and 0.065 gram per tonne gold (Assessment Report 19097). The vein is reported to strike at 350 degrees.
In 1995, two grab samples (ST-13 and -14) of quartz veining with chalcopyrite and malachite, taken approximately 450 metres to the southeast, assayed 14.44 and 0.44 grams per tonne gold, 710.8 and 23.1 grams per tonne silver, 0.76 and 1.34 per cent copper with 0.004 and 0.383 per cent zinc (Assessment Report 24284).
In 2004, a sample of mineralized subcrop (151491) from the main area assayed 0.04 gram per tonne gold, 13.0 grams per tonne silver, 0.094 per cent copper, 0.568 per cent zinc and 1.00 per cent lead, whereas two float samples (151467, 151468) of silicified tuff with disseminated pyrite, located approximately 1.3 kilometres to the northwest, assayed 0.669 and 2.472 grams per tonne gold with 10.4 and 99.0 grams per tonne silver (Assessment Report 27638).
In 2016, a sample (M456726) of aplite-breccia with clasts hosting quartz-galena-sphalerite-chalcopyrite stockworks from the former trenches on the main zone yielded 0.429 per cent lead and 0.189 per cent zinc, whereas a sample (M456715) from a narrow, (0.5 metre wide) zone of thin bornite-quartz-calcite stringers with malachite coatings in a chlorite-altered andesite cut by a monzodiorite porphyry dike, located near a small lake approximately 300 metres to the south-southwest, assayed 0.324 gram per tonne gold, 52.6 grams per tonne silver and 1.61 per cent copper (Assessment Report 36482).
Work History
Subsequent to staking the Peregrine and Falcon A claims in 1985 for Multinational Resources Inc, a 5-man crew completed contour soil sampling and limited stream sediment sampling. A 1986 rock and soil sampling program was successful in locating significant base metal and precious metal values in Areas "A" and "B". In 1989, Multinational Resources Inc conducted an exploration program on their Peregrine and Falcon A claims. Several new showings were reported to have been discovered and trenches were blasted or hand-dug. Fifty seven rock samples were collected.
In 1995, AGC Americas Gold Corp acquired 6 new claims totaling 120 units which tie onto the eastern boundary of their JD property (see 094E 171). This initial program was set up to sample gossans or zones of alteration seen on the property. Work was largely restricted to the Hairy claim in the north and Spur claim in the south. It resulted in the discovery of the JD-Hairy showing (094E 235). Work on the Spur occurred in the area of the Falcon A2 (094E 185) and Falcon A1 (094E 184).
In 2004, Stealth Minerals held the Gordo Group of claims which covered the Joanna occurrences and the Falcon occurrences (094E 185 and 185) to the south and Oxide Peak occurrences (094E 179, 180 and 181) to the west. Stealth collected 854 rock samples for analysis and 274 samples were taken PIMA rock spectroscopy for alteration identification (Assessment Report 27638). Ten silt and 30 soil samples were also taken. A number of samples were collected in the vicinity of the Falcon A2 (094E 185) and the Falcon A1 (094E 184) showings.
In 2005, Stealth Minerals Ltd. completed a further program of prospecting, geological mapping and rock sampling on the Gordo-Too-Oxide property.
In 2014, a program of prospecting and geological mapping was completed on the area as the Tod property.
In 2016, Seven Devils Exploration Ltd. completed a program of prospecting and rock sampling on the area.
In 2018, Arcwest Exploration Inc. conducted a program of geological mapping and minor rock sampling on the area. Also at this time, Freeport-McMoran completed a program of geological mapping, rock sampling, a 42.8 line-kilometre induced polarization survey, a 671 line-kilometre airborne magnetic survey on the area immediately southwest as the JD property.
