The mineralization on the Fenton claim is epithermal in style but carries significant base metals (zinc and lead) and only low levels of the typical epithermal indicator elements (arsenic, antimony and mercury). By 2013, the geological setting of the Fenton and Code claims is interpreted to be a Tertiary felsic flow dome complex. The area of the Eocene Ootsa felsic dome is underlain by andesitic rock of the Cretaceous Kasalka Group. Regional scale units also mapped include Lower Jurassic Telkwa Formation (Hazelton Group) consisting of volcanic rock and Lower Cretaceous Skeena Group consisting sedimentary rock. Intrusions of the Eocene Nanika Plutonic Suite and the Late Cretaceous Bulkley Plutonic Suite occur in the Code vicinity.

Mineralization occurs in an elliptical window of acid pyroclastic rocks consisting mainly of bleached dacitic tuffs and tuff breccias likely related to the Eocene Ootsa Lake Group. Sulphide mineralization consists of pyrite, sphalerite, and galena. Pyrite occurs disseminated and in veinlets, sphalerite occurs mainly in small veins and galena sometimes accompanies the sphalerite. The mineralization is often accompanied by intense clay alteration, silicification in places and manganese encrustations on cracks.


The claims were first staked in 1965 by Julian Mining Company following the discovery of a silver-lead-zinc geochemical soil anomaly in Code Creek. During 1966 to 1971, Anaconda performed induced polarization, magnetometer and soil surveys. In 1972, Helicon Explorations performed further geophysical and geochemical surveys and twenty-five diamond-drill holes (3350 metres). Vital Mines completed two diamond-drill holes (92.7 metres) on the property in 1976 and another two in 1978. Churchill Energy performed twelve percussion drillholes (546 metres) in 1977.

Drill work was conducted on the Code prospect from 1981 and 1985 inclusive (Drawing 375-3, Assessment Report 14029).

Noranda and Mattagami Lake Explorations performed geophysical and geochemical surveys during 1979. Mattagami Lake Explorations completed 9 diamond-drill holes (745 metres) in 1980 and a further 8 diamond-drill holes (946 metres) in 1981. Diamond drilling intersections included 0.68 per cent zinc, 0.49 per cent lead and 26.7 grams per tonne silver over 17 metres (hole 80-5); 0.43 per cent zinc, 0.34 per cent lead and 21.0 grams per tonne silver over 20 metres (hole 80-6); 0.22 per cent zinc, 0.17 per cent lead and 18.8 grams per tonne silver over 27 metres (hole 80-8) (Property File Rimfire Bradford, 1991).

In 1984, Cominco performed 22 percussion drillholes (1411 metres). Vital Pacific completed 6 diamond-drill holes in 1985.

In 1985, Vital did soil sampling, magnetometer and VLF electromagnetic surveys, and drilled six core holes aggregating 824 metres (Assessment Report 14029).

In 1986 to 1994, Baril Developments Ltd., a company associated with Electrum Resource Corporation, did various geophysical and geochemical programs for the purpose of assessment work.

In 1994, Baril Developments Limited collected 38 rock chip samples, 22 soil samples and a VLF survey on an area were recent logging had created new rock exposures. The property was again investigated by P. Daubeny and I. Morrison in 1995.

In 1995, Consolidated Samarkand Resources Inc. entered into an option agreement with Baril Developments. Samarkand did a geological reconnaissance program (Assessment Report 24359) that consisted of data compilation and field work.

In 1996 Samarkand completed a 61-kilometre line cutting program, and collected 3,254 soil samples on the Fen property which covered the Code prospect (Assessment Report 25509). The geochemical data identified highly anomalous geochemical values in silver, lead, zinc, copper, arsenic and barite north of the Silicic and Black Quartz Hills area.

From 1997 to 1998, Samarkand continued compilation work, processed and interpreted geochemical data, collected 24 additional soil samples and 8 rock samples (Assessment Report number 25909). Most or all sampling was done in the Code showing area.

In 2007, Electrum Resource Corp collected 224 soil samples and 38 rock samples of various types. Prospecting was also conducted along roads and soil lines covering an area of approximately 350 hectares. Soil and rock samples were done near and/or over the Code (093L 004), Tsalit Mountain (093L 258) and Fenton occurrence (093L 248). Altered outcrop samples (J+G 001 and 002) were taken in the vicinity of the Code occurrence and assayed 4.4 grams per tonne silver, 0.14 per cent arsenic and 0.09 per cent zinc with anomalous values in gold (Assessment Report 29792).

In 2012, on the Pimpernel and Fenton properties, Copper Mountain carried out a mapping and prospecting program resulting in a re-interpretation of the geology and determined that the rhyolite flow-dome complex together with past exploration results supported the potential for bulk tonnage epithermal silver-gold mineralization. The Pimpernel property covered the Hagas showing at the southeast corner of their claim block and the Fenton block covered the Code, Tsalit Mountain and Fenton occurrence.

In 2013, Copper mounted drilled 1329 metres in 50 percussion holes with 151 samples being submitted for assay. They also conducted 3.6 kilometres of IP surveying. A total of 31 soil samples were also collected. The 2013 work was in proximity to the Code (093L 004), Tsalit Mountain (093L 258) and Fenton occurrences (093L 248), which were covered at the time by their Fenton property.

Copper Mountain Mining Corporation conducted a two-phase drill program in May and October of 2014. In total, 2894 metres were drilled in 9 holes, targeting geophysical and multi-element geochemical anomalies. Drilling encountered lithological units consistent with a flow dome complex, and include crystal lithic tuff, rhyolite breccias demonstrating a variety of breccia textures, rhyolite flows, feldspar-phyric rhyolites, and aphanitic dikes. Mineralization is characterized by disseminated sulphides and 1 millimetre to 2 centimetre thick sulphide veinlets of very fine-grained pyrite, commonly associated with sphalerite, arsenopyrite, and galena. Highlights of assay results include 90 metres grading 0.11 gram per tonne gold, 4.4 grams per tonne silver, and 0.3 per cent zinc (hole 14FN-01); 84 metres grading 0.22 grams per tonne gold, 6.73 grams per tonne silver, 0.14 per cent zinc which includes a 4 metre intersection of 0.79 gram per tonne gold, 23 grams per tonne silver, and 0.25 per cent zinc (hole 14FN-02). Drill hole 14FN-03 intersected 24 metres grading 0.18 gram per tonne gold and 5.10 grams per tonne silver. Drill hole 14FN-06 intersected 3 metres grading 0.14 gram per tonne gold and 11 grams per tonne silver, and a separate 3 metre intersection of 0.43 gram per tonne gold, 29 grams per tonne silver, 0.29 per cent zinc, and 0.55 per cent lead (Assessment Report 35533).
