The Lynx showing is located on the southern portion of the Max (093K 020) claims south of Cripple Creek.
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 encompasses a large area (approximately 2 by 1 kilometres) of bleached, silicified, and mineralized rocks. This alteration zone may be part of a larger propylitic alteration halo associated with the large intrusive body on the Max claims to the north.
The main part of the Lynx showing occurs in a trench adjacent to the Germansen-Cripple logging road accessible from Fort St. James. A 3 square metre mineralized gossan zone occurs within light green, silicified and brecciated ash/dust tuffs of the Inzana Lake Formation. The gossan contains up to 30 per cent massive and crystalline pyrite, up to 5 per cent chalcopyrite and minor malachite. The rocks have a well-developed network of hairline fractures with alteration envelopes along them. Both propylitic and secondary potassic alteration are present. The rocks are strongly hornfelsed and contain abundant secondary biotite, however, no intrusive rocks have been identified on the property.
Adjacent to the gossan, a northwest trending, steeply dipping fault contains a 30-centimetre gouge zone that contains brittle quartz but no mineralization. Stratigraphically above the main gossan (approximately 1.25 kilometres west-northwest), tuffaceous siltstones and minor lapilli tuffs are sporadically skarnified. The sediments strike 102 degrees and dip 75 degrees south. Biotite and diopside hornfelsing are widespread for several hundred metres. Locally, a zoned garnet-epidote-diopside-biotite skarn contains concentrations of massive pyrrhotite (50 to 70 per cent) with minor flecks of chalcopyrite and possibly covellite(?). The meta-tuffs are interbedded with intermediate plagioclase-augite (± hornblende) porphyry flows/dikes. These contain disseminated pyrite and abundant epidote in streaky veins.
In 1992, Rio Algom drilled an IP target on the Lynx grid. The anomalies tested in DDH 92-3 to DDH 92-5, were caused by 2-3 per cent disseminated pyrite throughout and graphitic argillite in a regional west-southwest trending fault. The weak IP chargeability anomaly in DDH 92-6 resulted from 2-3 cent disseminated pyrite.
Work History
In 1981, Selco Explorations carried out an airborne electromagnetic and magnetometer survey over the area of the BIO option. In 1982, six diamond drill holes, totalling 519 metres, were completed on previously identified electromagnetic anomalies. Two of these drillholes (42-3-1 and 42-4-1) were located approximately 3.5 kilometres west and 5 kilometres northwest, respectively, of the Lynx occurrence.
In 1983, BP Explorations Canada Ltd. completed three diamond drill holes, totaling 301.8 metres, to test previously identified electromagnetic anomalies on the Sask 43-45 claims.
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. A sample (Lynx 2), taken in 1986, assayed 0.076 per cent molybdenum, 0.117 per cent copper and 3.0 grams per tonne silver (Property File - 840119).
On portions of the MAX 16 and 18 claims, further reconnaissance soil sampling was carried out in 1988. Also in 1988, Noranda Mining and Exploration Inc. completed a program of soil sampling the CL 1-2 claims located west of the Lynx occurrence.
In 1989, United Pacific Gold Ltd. completed a program of soil sampling and a 39.8 line-kilometre ground magnetic and electromagnetic survey on the Max property. 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. Drillhole 92-6 yielded 0.043 per cent copper and 0.109 per cent molybdenum over 2 metres of epidote-altered monzonite with disseminated pyrite and magnetite (Assessment Report 22271).
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.
During 2007 through 2010, Orestone Mining Corp. held the area as part of its Captain property.
In 2011, Xstrata Canada Corp. completed a program of soil sampling on the Lynx property. In 2013, a 12.3 line-kilometre ground magnetic survey was completed.
In 2019, IAMGOLD Corp. completed a minor rock sampling program on the Lynx property.
In 2020, IAMGOLD Corp. completed a 10.4 line-kilometre induced polarization survey on the Lynx property.
