The K-2 showing is located near the western edge of the Max (093K 020) claims approximately 3 kilometres northwest of Cripple Lake. The Max property was staked in 1986, to cover a series of airborne magnetic anomalies similar to known gold showings in the area.
The region is underlain by sedimentary and volcanic rocks of the Upper Triassic to Lower Jurassic Takla Group within the Quesnellia Terrane. The group comprises the informally named Inzana Lake, Rainbow, Witch Lake and Chuchi Lake Formations.
The Inzana Lake Formation is a sequence of epiclastic sediments derived from a volcanic source. It is underlain by fine-grained slates and sediments of the Rainbow Formation derived (in part) from a continental source. In turn, it is overlain by augite porphyry flows and agglomerates of the Witch Lake Formation and the subaerial maroon and green flows of the Chuchi Lake Formation.
The showing is a hydrothermally brecciated quartz-carbonate vein exposed in a subcrop zone approximately 2 metres wide which trends southeast. The vein contains bleached and milled wall rock and is strongly hematite stained. Up to 30 per cent chalcopyrite with minor malachite and an unidentified grey-silver coloured sulphide occur in the rock. The vein is hosted by clinopyroxene-rich flows and agglomerates of the Witch Lake Formation. Secondary biotite and epidote are locally abundant in the rocks around the showing. These alteration minerals are probably part of the large propylitic alteration halo associated with the large multiphase intrusion on the Max claims to the east.
A rock sample from the K-2 area in 2007 yielded up to 0.71 per cent copper and 40.8 grams per tonne silver from narrow quartz carbonate chalcopyrite filled shear zones in the K2 area (Assessment Report 29353).
Work History
The property was originally staked in late 1986 by Arthur A. Halleran, Arthur D. Halleran and Uwe Schmidt. They based their staking on the presence of a series of magnetic highs of similar magnitude to the nearby Tas and Mount Milligan properties. They also found placer gold in creeks draining these magnetic anomalies.
United Pacific Gold optioned the claims in 1986 and carried out a preliminary program of geological mapping, prospecting, soil sampling and collection of panned concentrate silt samples. Geological mapping identified widespread propylitic-altered andesitic flow and pyroclastic rocks and several small intrusive breccias, ranging in composition from diorite to syenite. On the Grif claims, grid soil sampling located areas of anomalous copper in soils.
On portions of the MAX 16 and 18 claims, further reconnaissance soil sampling was carried out in 1988. In 1989, United Pacific Gold Ltd. completed a program of soil sampling, minor rock sampling and a 39.8 line-kilometre ground magnetic and electromagnetic survey on the Max property. Float samples from the mineralized shear zone yielded 4.78 per cent copper and 110.1 grams per tonne silver (Assessment Report 20530).
In 1990, United Pacific Gold Limited sold its interest in the property to City Resources (Canada) Limited. Rio Algom Exploration lnc. entered into a joint venture agreement with City in 1990 and subsequently Rio Algom conducted an airborne VLF-EM and magnetic survey of the entire claim block, an airphoto interpretation of the surficial geology, grid soil sampling and geological mapping of the central grid area.
Rio Algom continued work during 1991. Geological mapping and soil sampling were continued on several small grids (Lynx, NW, Fire) within the claim block. The Fire is about 6 kilometres north of the Max occurrence (093K 020). An induced polarization survey was conducted to evaluate the numerous high-magnetic anomalies for porphyry-type copper-gold mineralization. In addition, a detailed rock sampling and follow-up soil re-sampling program was conducted on the central grid area.
In 1992, Rio Algom completed six diamond drill holes totalling 600 metres testing the anomalous Lynx and Fire zones on the Max claims. Volcanics of the Takla Group and sediments were intersected. Mineralization consisted of pyrite and graphitic argillite. Propylitic alteration was present in the volcanics. With the exception of DDH 92-6, all holes were drilled in fault zones. All gold and copper assays were at or below background levels.
From 1986 to 1992, a total of 10,030 soil samples and 264 rock samples were collected. Also, during this period 39.8 kilometres of ground magnetometer and VLF-EM surveying, 1660 kilometres of airborne magnetic and VLF-EM surveying and 87.5 kilometres of induced polarization surveying were done.
In 2007, David Blann restaked the area of the Max and K2 showings and collected a total of 234 soil, 39 silt, and 23 rock samples.
In 2010, Standard Metals Exploration Ltd. completed a detailed review and analyses of previously collected airborne geophysical surveys and soil sampling. Later that year, a 10.6 line-kilometre induced polarization survey was completed. In 2011, a further 44.6 line-kilometres of induced polarization surveying was completed.
In 2013, Aztec Metals Corp. completed a program of rock and soil sampling, geological mapping and a 653.0 line-kilometre airborne geophysical survey on the Max-K2 property.
In 2017, Aztec Metals corp. completed a further program of geochemical (rock and soil) sampling and geological mapping on the property.
In 2018, Jama Holdings Inc. completed a program of soil sampling and a 10.5 line-kilometre ground magnetic survey on the Max property.
In 2019, Thompson Creek Metals Co. Ltd. completed a program of rock sampling and 40 percussion drillholes, totalling 536.4 metres, on the Max property. A rock sample (A00348486) from the K2 occurrence yielded 0.111 per cent copper (Assessment Report 38569). Also in 2019, Thompson Creek Metals Company completed a 40.0 line-kilometre induced polarization on the Max-K2 property.
In 2020, Thompson Creek Metals Company completed 11 diamond drillholes, totalling 5441.0 metres, a 21.0 line-kilometre induced polarization survey and a 963.0 line-kilometre airborne magnetic survey on the Max property.
