The Hawk (AD) occurrence is located 4 kilometres south of a main south fork of the Osilinka River, about 70 kilometres northwest of the community of Germansen Landing.

The Hawk property occurs within the Early Jurassic Duckling Creek Syenite Complex, one of several phases comprising the Early Jurassic to Early Cretaceous Hogem Plutonic Suite.

The AD area is underlain by the contact, as shown by drilling, of alkali granite and mesocratic syenite. The AD vein and/or vein stockwork system contains sulphide-rich quartz up to 30 centimetres thick. The veins are typically grey quartz with significant amounts of pyrite, chalcopyrite and hematite; galena and sphalerite have been reported. The hematite gives the vein a distinct purplish red colouration which seems to correlate quite well with gold content. Where intersected in 2002 drilling, the vein is quite strongly fractured and brecciated, indicating proximity to a fault. This fault is believed to be a north-trending structure.

Unlike other veins discovered in the area, the AD vein has a distinct alteration envelope which extends up to 10 metres from the vein, including intense silicification. Quartz stockworking is common in this alteration zone and, in places, contains appreciable gold. Gold mineralization is restricted to veins and stockworks within the hostrock. This zone was traced for an apparent length of 200 metres. Rock chip samples from the zone yielded a high value of 96.0 grams per tonne gold across 3 metres (Assessment Report 21412, page 12). A subsequent short drill program (8 holes) intersected 19.9 grams per tonne gold over 1.5 metres of 9.3 grams per tonne gold over 2.8 metres downdip of the surface sampling.

Surface prospecting along the trend of the AD vein to the northwest confirmed the scarcity of outcrop in the forest for several hundred metres from the vein showings in the creek gully. Sample BCR045 was collected 770 metres along strike from the gully. This sample was a 20 by 30 centimetre piece of mineralized quartz vein float that yielded 22.1 grams per tonne gold, 24.8 grams per tonne silver and 0.010 per cent copper and suggests that the AD vein continues into this area (Assessment Report 27113). To the southeast, the AD vein trends into the valley where no outcrop is available. A single soil sample located 720 metres along strike from the gully yielded 118 parts per billion gold.

In 2002, Redcorp Ventures Ltd. core drilled the Hawk AD vein. Two drillholes totalling 312 metres were drilled into the AD vein. This is in addition to eight holes totalling just less than 900 metres which were drilled into the vein by Cyprus in 1991. The best Redcorp assay was derived from drillhole HK02006 which intersected 8.60 grams per tonne gold, 35.37 grams per tonne silver and 0.99 per cent copper over a 3.85 metre core length (1.6-metre estimated true width) within a wider section which assayed 4.66 grams per tonne gold, 25.06 grams per tonne silver and 0.48 per cent copper over an 11.59-metre core length (5.0-metre estimated true width) (Press Release, Redcorp Ventures Ltd., October 15, 2002). In 2010, a grab sample (2-17-9) from the AD vein assayed 22.6 grams per tonne gold and 19.1 grams per tonne silver (Assessment Report 32441).

The new 3P zone is located 250 metres northwest of the AD extension zone (Assessment Report 27113, Figure 8). It is defined by one grab sample from a 10 to 30 centimetre wide breccia vein striking 170 degrees and dipping 78 degrees, which assayed 30.6 grams per tonne gold and 15.2 grams per tonne silver (Assessment Report 27113).

A new quartz vein, the Zulu vein, was discovered 400 metres south of the AD vein in September 2002. It trends parallel to the AD vein and can be traced on surface intermittently for apparently 460 metres and ranges up to 1.2 metres wide. A grab sample from the vein assayed 46.80 grams per tonne gold and 121.0 grams per tonne silver (Press Release, September 17, 2002). Five drillholes tested the Zulu vein over a strike length of 60 metres and to a vertical depth of 100 metres. This vein, which has been traced on surface for 450 metres along strike over a vertical range of 150 metres yielded a best drill core assay of 29.27 grams per tonne gold, 6.80 grams per tonne silver and 0.82 per cent copper over 0.25 metre (0.2 metre estimated true width) (Assessment Report 27113). In 2010, a grab sample (6-17-9) from the Zulu vein assayed 52.4 grams per tonne gold, greater than 10 grams per tonne silver, greater than 1 per cent lead and 0.18 per cent copper (Assessment Report 32441).

The Zulu North zone is located 190 metres north of the western end of the Zulu vein. It is defined by a single sample from a 10 centimetre wide rusty, white quartz vein with no visible sulphides. This vein was oriented at 220 degrees/60 degrees dip and assayed 30.6 grams per tonne gold and 2.1 grams per tonne silver (Assessment Report 27113).

A second new quartz vein, the Rainbow vein, was discovered in 2002. It is located 200 metres south of the Zulu vein, is exposed over a strike length of 315 metres and reaches up to 0.75 metre true width. A chip sample over 0.75 metre assayed 18.00 grams per tonne gold and 39.00 grams per tonne silver (Press Release, Redcorp Ventures Ltd., October 4, 2002).

The Lake zone is located 375 metres south of the Rainbow vein, approximately half-way between it and the Radio veins. It was initially indicated by a Cyprus Canada rock sample which assayed 9.4 grams per tonne gold and 0.49 per cent copper (no silver assay) (Assessment Report 21412). Prospecting by Redcorp in 2002 discovered quartz vein subcrop which assayed 14.3 grams per tonne gold, 17.4 grams per tonne silver and 0.683 per cent copper from a grab sample. A second area of quartz vein in subcrop occurs 80 metres east-southeast of here, and a grab sample from this location yielded 1.36 grams per tonne gold, 3.8 grams per tonne silver and 0.112 per cent copper (Assessment Report 27113).

The area in the vicinity of the Hawk property was first staked by Amoco Canada in 1972 following a regional exploration program aimed at discovering copper-molybdenum porphyry deposits within the Hogem batholith. Amoco drilled four holes in 1974, none of which were assayed for gold content. Amoco’s target was disseminated copper mineralization apparently hosted in a biotite-muscovite gneiss unit trending northwesterly and located immediately northeast of the Radio zone. No subsequent work has been conducted on this zone.

The Amoco claims were allowed to lapse, and no work was recorded until the area was staked by Cyprus Gold (Canada) Ltd. in 1990. Gold mineralization at the AD, Radio and SW zones was discovered by Cyprus during a reconnaissance program of geological prospecting, soil and rock sampling and proton magnetometer surveying. Several significant, open-ended copper soil anomalies were outlined by Cyprus but were not followed up. The gold zones were subject to more detailed grid mapping, soil and rock sampling, magnetic/VLF surveying and hand trenching.

Cyprus completed eight BQ-size diamond-drill holes totalling 898 metres in October of 1990. The best results from this program were 6.86 grams per tonne gold over 5.15 metres (including 19.9 grams per tonne gold over 1.5 metres) in hole HK 90-l, and 9.3 grams per tonne gold over 2.8 metres in hole HK 90-2 (Assessment Report 21412). Both of these holes were drilled on-section with the AD showing, where surface samples yielded 96.0 grams per tonne gold over 3.0 metres (Assessment Report 27113, Figure 13). Cyprus did not do any follow-up work to the 1990 program, and the claims were allowed to lapse in 1995.

Immediately following the expiry of the Cyprus claims, the Hawk Property was staked by Nicholson and Associates and R.M. Durfeld. Work by this group was completed under the name of Castleford Resources Ltd. The 1995 work program of Castleford was focused on expanding and detailing the known zones particularly the AD and Radio (094C 139) zones, although some prospecting was also completed. All of the claims except HK3 and HK4 were allowed to lapse subsequent to Castleford’s work program.

Redcorp Ventures Ltd. re-staked the initial claims in late 2001, acquired the HK3 and HK4 claims early in 2002, and staked the Hawk 5 through 15 claims in June of 2002. The 2002 program of Redcorp Ventures Ltd. included the establishment of 23.65 kilometres of grid and the collection of 813 soil and 99 rock samples. The drill program involved the drilling of 12 BQTK diamond-drill holes totalling 1534 metres. Five holes were drilled on the Zulu vein, two on the AD vein and five on the Radio vein (094C 139). Redcorp carried out surface mapping, sampling and soil sampling in 2002 in the vicinity of the AD and Southwest (094C 140) zones.

Redcorp subsequently experienced financial difficulty and allowed most of the Hawk claims to expire and returned the key claims to Durfeld in January 2010.

The most recent exploration at Hawk was completed by Alton Resource Corp. in 2010 and 2011. The first campaign completed in July 2010 took drill core originating from drill programs completed in 1990 and in 2002 that was in disarray and reorganized it. Twenty-two silt samples were collected and analyzed and, along with the historic data set for the project, digitized. In the second campaign, completed in late September 2010, additional soil and rock sampling (largely focused on the alkalic copper-gold potential) was completed in the south-central property area. During 2011, Alton expanded the claim holdings by tenure acquisition and completed a high-resolution helicopter-borne magnetic survey over the entire claim holdings. A total of 397 line kilometres was flown.

In 2015, R. Durfeld conducted geological mapping, geochemical surveying (17 silt and 31 rock samples) and prospecting on the Hawk property. In 2017, R. Durfeld conducted geological mapping and geochemical surveying (19 rock, 30 core and 42 soil samples) on the Hawk property.
