Work History

Staked as Jim cl 1-4 (Y26618) in July 1968 by M. Zulps for Zulco Exploration Ltd. 
 
Re-staked as EL cl 1-40 (YA14059) in November 1976 by the Prism Joint Venture (Prism Resources Ltd., Placer Development Ltd., Granby Mining Corporation, Chieftain Development Company Ltd. and Craigmont Mines Ltd.).
 
Prism added EL cl 41-70 (YA15576) in July 1977 to cover open ground between these claims and the Dee claims (MINFILE occurrence 106D 008) located to the south. The original EL claims (i.e. 1-40) were explored with geological mapping, grid soil sampling and several EM geophysical test lines later in the summer.
 
Re-staked within R cl 105 -1295 (YC68334) in July 2008 by ATAC Resources Ltd as part of the Rau Trend within the larger Rackla Gold Project. During the summer of 2008, the company established a small soil sampling grid over the occurrence (i.e. gossan) as well as performed a property-wide helicopter-borne magnetic and VTEM survey. The soil sampling program was part of a larger property wide program carried out by the company. In 2009, ATAC prospected and collected rock samples from the occurrence area.
 
In early 2010, ATAC Resources flew an airborne ZTEM/magnetic survey over much of the property. The company followed up with ground induced polarization (IP) and gravity geophysical programs, as well as detailed soil sampling. Areas located northwest of the occurrence were explored with contour soil samples. Later in the summer the company collared 5 diamond drill holes (1,133.46 m) northwest of the gossan near surface mineralization.
 
In 2011, ATAC Resources carried out silt sampling and follow-up grid soil sampling north and northwest of the occurrence area. The company used the results from these surveys and previously obtained geophysical surveys to guide a 19 hole diamond drill (3,784.75 m) program.
 
During 2012, ATAC Resources completed soil sampling, prospecting and ground-based VLF-EM, magnetics and gravity geophysical surveys.  
 
Regional & Property Geology
 
The occurrence lies with the Rau Trend between the Dawson and Kathleen Lakes thrusts, which form part of a band of regional-scale thrust faults that imbricate rocks of Mackenzie Platform and Selwyn Basin. The occurrence area lies on the western margin of ancestral North America and is underlain primarily by shallow water carbonate and clastic sediment rocks of the Mid-Proterozoic to Paleozoic Mackenzie Platform and the Neo-Proterozoic to Paleozoic, regionally metamorphosed Selwyn Basin clastic rocks. These rocks formed a fault-bounded sediment package which was thrust northeasterly during Jurassic to Cretaceous times by the Dawson and Kathleen Lakes thrust faults onto predominantly Proterozoic rocks. Following thrust faulting, Late Cretaceous (94-90 million years) intermediate to felsic plutons of the Tombstone Suite were emplaced (Mortensen et al., 2000). A second compressional orogenic event around 65 million years saw the emplacement of felsic intrusives assigned to the McQuesten Suite.
 
Other than the immediate area surrounding the Tiger deposit (MINFILE occurrence 106D 098), the occurrence area has not been geologically mapped in detail. ATAC Resources (AR 096936) has mapped 3 main units in the area comprising the Rau Trend:
1. Cambrian to Ordovician massive, grey dolostone,
2. Ordovician and/or Silurian bedded, grey and buff silty limestone and massive white limestone, and
3. Silurian to Devonian thick, bedded dolostone and limestone.

The company has assigned all three units to the Cambrian to Devonian Bouvette Formation. Colpron’s 2013 geological map generally supports this interpretation; however it uses slightly different age dates and doesn’t include the oldest rocks (Cambrian to Ordovician dolostones) within the Bouvette formation.

Thin volcaniclastic horizons assigned to the Ordovician Marmot Formation are interbedded with the Ordovician and/or Silurian limestones and a narrow sliver of Mid-Proterozoic Fifteen Mile Group dolostone underlies the Bouvette Formation rocks to the southwest. Devonian and Mississippian Earn Group comprised of black shale and chert bounds the Bouvette Formation to the south east and north in the southern half of the Rau Trend property.
 
The Ocelot showing occurs within the favourable Bouvette Formation carbonate sequence and lies within a regional structural corridor that hosts the Tiger gold deposit in the same rock units, 15 km to the southeast. The showing is identified by a natural spring gossan (the original EL claim gossan) of dolomite rubble cemented by iron oxides and a vegetation kill zone measuring approximately 300 by 150 m. Moderately to strongly anomalous lead and zinc-in-soil values form a 2.3 by 1.0 km intermittent linear shaped anomaly that trends westerly from the gossan.

Mineralization & Results

Mineralization at the Ocelot occurrence consists of medium to coarse grained pyrite and varying concentrations of low iron sphalerite and medium to coarse grained galena ± tetrahedrite. Sulphide mineralization occurs within a steeply dipping northeast trending fault that cuts an extensive dolomitized limestone sequence with narrow volcaniclastic beds locally exhibiting structural and fluid altered breccias. ATAC Resources reports that the types of mineralization that most closely match the available data are carbonate replacement deposits or mantos.

The original EL claims were staked on a zinc silt anomaly outlined by the Geological Survey of Canada's Operation Keno in 1964. Soil sampling outlined 250 m long by 100 m wide zinc anomaly roughly coincident with a gossan. Only one sample within the gossan returned anomalous lead (800 ppm) and silver (3.8 ppm) values. Soil pits dug on the gossan all returned an initial increase in zinc value with depth and then a drop off in values. Test EM geophysical lines outlined a flat lying structure such as an unconformity or fault. The joint venture concluded that the gossan was likely related to a water course along a permeable zone which may be an unconformity or fault.
 
ATAC Resources initially staked the R claims in 2008 to protect favourable stratigraphy trending northwest from the recently discovered Tiger deposit. Soil sampling and geophysical surveys outlined a number of geochemical anomalies coincident with gravity, IP, ZTEM airborne EM anomalies and a low level magnetic anomaly. Follow-up prospecting of one of the coincident geochemical/geophysical anomalies in a largely overburden covered area near the original gossan identified a small vegetation kill zone where abundant boulders and cobbles of angular silver-lead-zinc massive sulphide and oxide mineralization occur. Surface samples collected from the Ocelot discovery area returned up to 2 810 g/t Ag, 80.55% Pb, 40.5% Zn and 68.10 g/t indium.

Drilling completed in 2010 and 2011 by ATAC Resources at the Ocelot occurrence has identified mineralization over a 230 m strike length and to a depth of 150 m. Mineralization remains open downdip and possibly along strike to the northeast. The 2010 drilling program was reconnaissance in nature and tested geophysical anomalies northwest of the surface discovery showings. Four of the five holes were successively completed. Only hole OC-10-01 intersected significant mineralization, returning an average of 360 g/t Ag, 9.83% Pb, 25.06% Zn and 48.2 g/t indium over 4.23 m.
 
The first 5 diamond drill holes collared in 2011 were located near the edge of the gossan at the east end of the lead and zinc anomaly. Four of the five holes intersected significant mineralization with hole OC-11-09 returning the best grade interval. The hole returned 41.72 m grading 145.43 g/t Ag, 3.36% Pb and 11.65% Zn. Seven of the remaining 14 diamond drill holes returned significant results. Hole OC-11-11 returned 37.91 m grading 188.07 g/t Ag, 8.69% Pb and 6.06% Zn, including a 14.82 m intersection which returned 400.18 g/t Ag, 20.44% Pb and 9.50% Zn. Other significant results include hole OC-11-14 which returned 35.64 m grading 46.43 g/t Ag, 1.36% Pb and 8.12% Zn and hole OC-11-16 which returned 35.57 m grading 56.53 g/t Ag, 1.63% Pb and 9.73% Zn.
 
Prospecting at the Ocelot occurrence in 2012 resulted in the discovery of a new small high grade Ag-Pb-Zn showing northwest of the main Ocelot drill area, dominantly noted as galena with coarse-grained barite crystals. Samples taken from this area returned up to 2960 g/t Ag, 60.3% Pb, 45.8% Zn and 1.0% Sn.
