Capsule Geology

The Goathead molybdenum prospect is located at the toe of the small glacier on the south side of the cirque at the headwaters of Goathead Creek, 57 kilometres north of Hazelton. The mineralization was discovered in 1969.

The area is underlain by Middle Jurassic to Lower Cretaceous Bowser Lake Group clastic sedimentary rocks which consist of argillites and siltstones with minor carbonate layers. The molybdenum mineralization occurs within and peripheral to an elongate east-west trending stock, 1500 metres long by 600 metres wide. The stock, of the Late Cretaceous Bulkley Intrusions, is porphyritic in texture and granodioritic in composition. Biotite in the intrusion has been dated by potassium/argon techniques at 51 million years (Geological Survey of Canada Open File 2322). Dikes of granodiorite, aplite and diorite cut the stock and sedimentary rocks.

Molybdenite, chalcopyrite and pyrite occur in a weakly developed quartz vein stockwork and disseminated in altered areas within the granodiorite (Assessment Report 10290). Pyrite, pyrrhotite, and minor scheelite, chalcopyrite and molybdenite occur in hornfels near the eastern contact. Scheelite also occurs in sparse veins and along fractures in fresh argillite, and in garnet-epidote skarn in calcareous beds near the granodiorite contacts. Locally, an intense quartz vein stockwork is developed with K-feldspar alteration, silicification and a late argillic alteration.

The best drill intersection was 33 metres grading 0.193 per cent molybdenite in drill hole K-1-81 (Assessment Report 10290).

WORK HISTORY

Canex Placer Ltd. was the first group known to have worked on the property. It was initially known as the Ole Group, and was held by Canex from 1961 to 1963. The Canex work focused on low-grade molybdenum-copper mineralization in rusty hornfels adjacent to the granodiorite stock.

The Fog and Frost claims cover showings formerly known as the Ole group. They comprise 20 recorded mineral claims held by Amax Exploration, Inc. Work by the company in 1966 included the mapping of an area 731 by 1463 metres, the drilling and blasting of two trenches having a total length of 42 metres, and diamond drilling in one hole to a depth of 453 feet. The Amax work focused on molybdenite mineralization in quartz vein stockworks in the granodiorite stock. The assay results from the Amax drilling are not available in the public domain.

Sicintine Mines Ltd., which was organized in August 1967, acquired the property and subsequently optioned it to Canadian Superior Exploration Limited. A program of trenching and sampling was carried out during the year.

The property was staked by John Bot of Smithers in 1977, and optioned by Texasgulf Inc. in 1979 after high-grade angular float was observed (Bending, 1982) near the edge of the glacier (Fig. 4). During 1981, two diamond drill holes totaling 712.5 metres were completed. Drill hole K-1-81 was drilled to a depth of 421.5 metres, intersecting 30 metres grading 0.203 per cent MoS2 between 342 and 372 metres. Hole K-2-81 was drilled to a depth of 291.0 metres. Table 2 (below) summarizes the higher assay results obtained in the Texasgulf drilling.

The BMS claim was staked in 1995 by Ronald Ross Blusson and Ronald Hugh McMillan because of the encouraging results obtained in Texasgulf drill hole K- 1-8 1. A one day visit was made to the properties and 5 rock samples were taken.

Three Kisgegas (Goathead Creek) claims were restaked by Ronald Ross Blusson and Ronald Hugh McMillan in the mid-2000s because of the encouraging results obtained in Texasgulf drill hole K-1-81. McMillan visited the property in 2005 and obtained character samples of mineralized material and accurate GPS locations for the Amax and Texasgulf drill holes.

In 2007, optioner Molycorp Gold Corporation completed a 36 kilometre airborne magnetometer survey over the Kisgegas (Goathead Creek). The option was terminated and reverted to Blusson and McMillan.

In 2013, Blusson and McMillan held 3 claims encompassing the Kisgegas (Goathead Creek) porphyry molybdednum occurrence.
