The Horn occurrence is located approximately 7 kilometres north of Motase Lake (Property File - Canadian Superior Exploration Limited, Maps from Company Files, circa 1973).
Mineralization is hosted in hornfelsed sediments intruded by a granodiorte stock to the north and a series of northeast-trending porphyry dikes to the south. The sediments could belong to either the Upper Jurassic to Lower Cretaceous Bowser Lake Group or the Lower Jurassic Telkwa Formation (Hazelton Group). The intrusions are possibly related to the Eocene Kastberg Intrusions or granodiorite of the Late Cretaceous Bulkley Plutonic Suite. The granodiorite is a 300 by 2000 metre plug with a metamorphic aureole ranging from 60 to 275 metres in width (Assessment Report 5323).
Disseminated molybdenite and variable amounts of chalcopyrite occur in country rocks, aplite dykes and quartz veinlets. Pyrite is common and is pervasive within the argillites surrounding the intrusives.
Assay values range between 0.003 per cent and 0.08 per cent molybdenum sulphide (MoS2) with a single sample reportedly containing 0.55 per cent MoS2 (Assessment Report 5323).
WORK HISTORY
Canadian Superior Exploration (CSE) staked 48 claims in 1972 to form the Horn Property based on reconnaissance work in the area. In 1973, CSE conducted an exploration program that included prospecting and geological mapping over the entire property as well as soil, silt, and rock geochemical sampling (Assessment Report 04731). A soil survey of 284 samples identified zones of anomalous molybdenum (= 20 ppm molybdenum) but did not identify significant copper anomalies. The most significant molybdenum anomaly covers an area 2000 by 700 metres oriented west-northwest with molybdenum concentration ranging between 20 and 240 ppm. Molybdenum concentration in silts ranged up to 105 ppm molybdenum and identified the soil anomaly. Trenching within soil anomalies identified mineralized hornfels sediments.
In 1974, Ducanex Resources Ltd (for CSE) created a geological map covering an area approximately 900 by 2900 metres in size. A large 2300 by 300 metres W-NW trending granodiorite body was identified in the southwest portion of the property. Quartz-molybdenum mineralization was identified to be most significant in the hornfels surrounding the intrusive body. Nine rock samples were analyzed for Mo, Ag, and Au. Assay values range between 0.003 per cent and 0.08 per cent molybdenum sulphide (MoS2) with a single sample reportedly containing 0.55 per cent MoS2. In addition to rock sampling, 689 soil samples were collected and analyzed for molybdenum. The most significant soil anomalies were observed in the hornfels north of the granodiorite body (Assessment Report 5323).
Amoco Canada Petroleum Company Ltd conducted a soil survey over the granodiorite intrusive body identified by CSE (Assessment Report 08849). The survey consisted of 234 samples taken on a grid with a line spacing of 120 metres and a sample station spacing of 60 metres. Samples were analyzed for copper and molybdenum, 48 samples for gold. Four anomalous zones (>100 ppm molybdenum) were identified. The most significant anomaly covers an area of 450 by 200 metres with molybdenum values ranging between 100 and 280ppm. Soil anomalies are associated with hornfels black shale peripheral to the granodiorite intrusive body. Gold concentrations in soils are reported to have ranged from 4 to 10 ppb with a maximum value of 35 ppb (Assessment Report 08849). Workers did not identify copper or gold soil anomalies.
In 1981, Assessment Report 9522 described geochemical sampling of hornfels and porphyry rock on the Horn claim group for JMT Services Corp. Hornfels north of the granodiorite is reported to have higher molybdenum concentrations, but values are not reported (Assessment Report 9522).
In 1985, Mr. M. Zink commissioned D.D.H. Geomanagement Ltd. to map the geology, prospect and produce a reconnaissance geochemical map for the GOLD mineral claims 5 - 12 and 14. Work was conducted on the western side of the claim block on Gold #8 claim (Assessment Report 14073). This work identified a 600 by 60 metre auriferous gossan zone on the west side of the property associated with a sericite-altered dacite porphyry dike. Soil sampling identified anomalous molybdenum, zinc, copper, cobalt, manganese, arsenic and gold peripheral to the dyke. At the Gold #8 showing (094D 118), a sample of a 5-centimetre-wide quartz-galena-sphalerite vein returned an assay value of 16.8 grams per tonne gold, 368.57 grams per tonne silver, and 0.82 per cent combined lead and zinc (Assessment Report 14073).
In 2008, the Horn property, consisting of the Walt, Walt Ext., and Horn 1 claims, was visited on behalf of Paget Moly Corporation. Mapping and rock sampling was conducted in the Gossan Zone (Gold #8 (094D 118) on the western portion of Paget's Horn property (Assessment Report 30336).
