The Norfa occurrence is centred on a showing of minor copper-molybdenum mineralization, but it informally covers several other showings within a few square kilometres between Franklyn Arm of Chilko Lake and Good Hope Mountain to the south (see maps in Assessment Reports 3271, 8295; Property File - Renshaw, R.E., 1975). It is only about 2 kilometres east of the more significant Daisie occurrence (092N 026), but the Daisie is skarn-hosted whereas the Norfa showings are apparently mainly weak, porphyry-type mineralization (Assessment Report 8295; Bulletin 81).

The area of the Norfa occurrence is dominated by a differentiated biotite granodiorite to quartz monzonite intrusion of the Late Cretaceous to Paleocene Bendor suite. The granodiorite was intruded into the Lower Cretaceous Tchaikazan River succession consisting of andesitic, dacitic and basaltic tuffs and breccias, and minor argillite (Geological Survey of Canada Open File 1163; Assessment Reports 3271, 8295). Regionally, strata strike northwest and dip moderately to steeply northeast, although their orientations may be modified by the intrusion. Mafic and lamprophyre dykes occur locally.

The contact between the granodiorite intrusion and the volcanics may be sharp or gradational. Hornfelsing and chloritic alteration is common. Several gossanous zones are present on or near the granodiorite contact (Assessment Report 8295). These are generally mineralized with disseminated pyrite and pyrrhotite, locally accompanied by very minor chalcopyrite and molybdenite. The Norfa occurrence is centred on one such zone, a northeast-trending, gossanous and hornfelsed band separating the volcanics from a subunit of argillite, about 400 metres west of the granodiorite (Assessment Report 3271).

Within the granodiorite itself are widely-spaced fractures, between 0.25 and 1.0 centimetre thick, filled with quartz which is locally vuggy (Assessment Report 8295). They strike east and dip moderately north or south. Some veins contain weak chalcopyrite and molybdenite. It is described as a poorly-developed porphyry system (Assessment Report 8295).

Reported values of copper and molybdenum are low, although samples from two zones contained 0.1 per cent tungsten (Assessment Report 8295).

WORK HISTORY

Mr. Alec Ducharne and Mr. Thomas J. Gordon conducted exploratory work over the Daisie claims area for a number of years before the property was acquired by Gordon Resources Limited.

In July 1971, an airborne magnetometer survey was carried out over the eastern claims area for Conshell Resources Ltd. (Assessment Report 3477).

In October 1971, a geological Assessment Report was released on the Norfa claims for Beaumont Resources Ltd. (Assessment Report 3271).

In October 1972 the Alta claims were staked just south of Franklyn Arm on behalf of Conshell Resources Ltd. (Assessment Report 3948). An airborne geophysical survey consisting of combined aeromagnetic, electromagnetic and radioactivity testing was conducted. There was a coincidence of high magnetomer and high electromagnetic readings on Alta claims 5, 6, 7, 8, 24, 25, 26, 27 and 28. The survey covered an area of about 3000 acres.

During 1978, twenty-two EX diamond drill holes, totalling 705 meters, were drilled for Gordon Resources Ltd. on the Daisie 1-19 claims, which were staked in 1962. Trenching and stripping over the previous 20 years exposed intermittent mineralization over a 914 metre length (Assessment Report 7156).

In 1979, Gordon Resources owned 10 per cent and Canada Tungsten owned 90 per cent of the Daisie 1-8 claims (Assessment Report 7574). A small-scale diamond drill program, utilizing a Winkie diamond drill, was executed on the Daisie 3 mineral claim. Three AX-sized core holes were drilled at 2 sites for a total of 148 metres. Two of the holes, DDH 79-1 and 79-2, successfully penetrated the overburden; 34 metres and 111 metres of core were drilled respectively. Tungsten mineralization in both drill holes was low grade (trace of 0.01 per cent W03) even in skarnified sections that were encountered within the upper 4.6 metres of the limestone. No assays were run on the core because of the lack of visible copper, molybdenum and tungsten mineralization.

In 1979, the C.T. claim group consisting of 23 claims (460 units) were located and staked for Canada Tungsten Mining Corporation Limited. In 1980, a combined geological/geochemical program was carried out by Canada Tungsten using a field crew of seven (Assessment Report 8295). Geological mapping and heavy mineral sampling were done with continuous helicopter support. A total of 42 rock samples, 27 heavy mineral samples, and 660 silt samples were collected. A set of 1:5,000 orthophotographic maps with 20-meter contour spacing was used to produce a 1:25,000 geologic map. Heavy mineral, conventional silt geochemical and rock samples were also plotted on the geologic map. Analytical results of heavy mineral concentrates indicated five areas of interest.

In 1980, diamond drilling was conducted on the Daisie 1 to 8, 2-post claims by Gordon Resources Ltd. (Assessment Report 8295). Drill setups were placed on and near surface showings of copper, molybdenum and tungsten mineralization. The Daisie claims were completely encompassed by Canada Tungstens C.T. Claim group. Holes A, B and C were located near the Number 2 showings where four trenches exposed limestone, skarn and quartz containing chalcopyrite, pyrite, pyrrhotite, molybdenite and scheelite.
