Lower Jurassic Hazelton Group volcanics of the Telkwa Formation are comprised of andesitic to rhyolitic flows, tuff and breccia. The Fly prospects is hosted by two quartz-sericite-pyrite (phyllic altered) zones within the southern part of the Sunsets stock, a Late Cretacious quartz-feldspar porphyry stock of the Late Cretaceous Bulkley Plutoinic. The intrusion is an epizonal body which produced a domal effect on the Hazelton rocks.

Locally, the volcanics are comprised of fragmental tuff with minor intercalated flows. The volcanics are moderately to intensely hornfelsed as the intrusive margin is approached. In some areas the volcanics are skarned producing calc-silicate minerals and garnet with or without disseminated chalcopyrite and magnetite. Disseminated pyrite in the volcanics increases towards the contact.

Hydrothermal alteration in the core area of the intrusive produced argillic alteration due to the breakdown of feldspar. As well, widely spaced sub-parallel quartz veins, ranging between 2 to 5 centimetres in widths host pyrite, chalcopyrite, and molybdenite.

Two quartz-sericite zones host pyrite, molybdenite, and minor chalcopyrite along joints and fractures. One zone is called Fog (093L 046) and the other is called the Fly (093L 045).

Quartz-pyrite molybdenite chalcopyrite veins 2 to 5 centimetre wide and trending predominantly northeasterly and dipping southeast are associated with the alteration zones. Potassic alteration, suggested by pink feldspar alteration envelopes along fractures and quartz veins, is reported at a lower vertical level beneath the sericitic zones.

Vein abundance in general is sparse but the western alteration zone (Fly), measuring 300 to 600 metres by 1000 metres, contains between 10 and 25 veins per metre and is flanked by a copper in soil anomaly. Maximum results from 1980 were reported to be 0.102 per cent molybdenum and 0.11 per cent copper (Assessment report 8444).

In 1980, a sample from the west zone (Fly) (S.L. 15) showing assayed 0.025 per cent molybdenum and 0.04 per cent copper. Another sample from a shear assayed 0.003 per cent molybdenum and 0.11 per cent copper (Assessment Report 8444).

In 2008, the best values obtained from the Fly sericitic alteration zone were also from the margins of the zone having 0.22 per cent copper, 0.95 gram per tonne gold and 504 grams per tonne silver from quartz-freibergite veinlets on the west side of the zone and 0.14 per cent copper, 0.46 gram per tonne gold and 110 grams per tonne silver from a galena-bearing stockwork near the east side (Assessment Report 30731). Samples of disseminated mineralization in the core returned maximum values of 0.05 per cent copper and 0.041 per cent molybdenum (Assessment Report 30731). In 2007, significant molybdenum results were obtained from the far eastern and southern margins of the Fly phyllic alteration zone with results of 0.0605 per cent molybdenum and 0.151 per cent molybdenum from quartz-molybdenite veinlets (Assessment report 30188).

WORK HISTORY

The Morning claim was staked on the showings by F.M. Dockerill in 1905. Other showings, at higher elevations (about 1980 metres) were staked in 1905 by William McCullough as the Sunset claim. Near the summit of the mountain, at about 2133 metres, P.R. White located the Sunrise claim. Assessment work on the above claims was limited to open cutting. The claims subsequently lapsed and the showings were in part restaked as the Highgrade claim in about 1912 by Joe Cochrane and Charles Seeber. Work to 1914 included a 4.6 metres drift-adit and a few open cuts.

In 1966 and 1967, copper-molybdenum stream sediment anomalies were delineated by Noranda Mines Ltd. in southwest part of the Sunsets stock. Mapping, soil geochemistry, trenching and VLF-electromagnetic surveys indicated a typical "porphyry" environment with several possible conductors (Assessment Report 1189).

In 1968, soil geochemical and horizontal loop electromagnetic surveys with minor mapping, delineated a western copper (rimming Fly) and eastern copper-molybdenum (Fog) soil anomaly, the latter with a weak conductive zone coincident with previous VLF anomalies. This was followed by 152.4 metres of diamond drilling in 2 holes on the lower Fly by Whitesail Mines Ltd. but results were not reported (Assessment Report 1922).

In 1970, diamond drilling of 478 metres in 3 holes (on the upper Fly) was conducted by Ducanex Resources Ltd. under option from Whitesail Mines Ltd. but results not reported (Assessment Report 9770).

In 1980 and 1981, nine spot check grab samples were collected by Canadian Nickel Company Limited for Redfern Resources Ltd. These yielded significant values in molybdenum, and copper from the Fog, and Fly phyllic (sericitic) alteration zones (Assessment report 8444). This was followed by mapping, rock and soil geochemistry to confirm previous data, and an evaluation of old drill core stored on site (Assessment Report 9770).

In 1991, significant copper in rock (up to 0.59 per cent copper) was obtained in the north to northeastern Sunsets stock area by Skeena Resources Ltd (Assessment report 21765).

In 2007, Lions Gate Energy Corp conducted an Aerotem airborne geophysical survey on parts of the El Toro property which also covered the Sunset Basin area that contains the Fly (093L 045) and Fog (093L 046) and the new Glacis and North Sunset showings (Assessment Report 29456). Forty rock samples were also collected, including some from the Sunset Basin area (Assessment Report 30118)

The 2008, El Toro program of Lions Gate Energy Inc involved mapping, prospecting, 87 rock and 15 soil geochemical samples, GPS surveying of previous diamond drill hole collars, and underground and surface workings, an evaluation of the property (Assessment Report 30731). Sampling and geological work was completed in 2008 on the Sunset Basin area. This was followed by a 1495 line-kilometre airborne magnetic and electromagnetic geophysical survey (Assessment Report 30982) which covered various parts of the El Toro property including the Sunset Basin area that contained the Fly (093L 045) and Fog (093L 046) and the new Glacis and North Sunset showings.

In 2009, on the El Toro property Lions Gate conducted a program that involved mapping, rock (37) and soil (568) geochemical sampling, and additional GPS surveying of previous diamond drill hole collars and old workings. However, no work was completed in this year on the Sunset Basin showings that contained the Fog, Fly, Glacis and North Sunset.

Refer also to King (093L 041) for general information on the El Toro property, a large property that was worked by of Lions Gate Energy Inc from 2007 to present (2015) and encompassed the Sunset Basin which contains the Fly, Fog, Glacis and North Sunset.
