Work History
 
Staked within R cl 1-1295 (YC68334) in Jul/2008 by ATAC Resources Ltd. The claims are part of the larger Rackla Gold Project and were staked following the discovery of gold mineralization in 2008 at the company’s Tiger occurrence (Minfile Occurrence #106D 098) located approximately 5 km to the southeast. Following staking the company carried out a helicopter-borne magnetic and variable-time domain electromagnetic survey over the newly staked area.
 
In 2009 ATAC Resources carried out grid and contour soil sampling followed by prospecting and rock sampling of anomalous areas including the Cougar occurrence. In 2010 ATAC Resources carried out a large exploration program on the Rau portion of its Rackla Gold property. The company completed air-borne ZTEM and aeromagnetic geophysical surveys over the majority of the Rau trend as well as soil sampling over the Cougar occurrence.
 
In 2012, the company completed soil sampling and in 2013 completed further soil sampling in the area. Follow up rock geochemistry and prospecting was completed in 2015.
 
Geology
 
Regionally, the occurrence lies 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 carbonate platform rocks of Mackenzie Platform which are in turn overlain by Paleozoic Selwyn Basin clastic rocks. The rock package formed a fault-bounded package which was thrust northeasterly during Jurassic to Cretaceous times by the Dawson and Kathleen Lakes thrust faults onto predominantly Proterozoic rocks. Following faulting, Late Cretaceous (94-90 million years), intermediate to felsic plutons of the Tombstone Suite were emplaced. A second intrusive event around 65 million years saw the emplacement of felsic intrusives assigned to the McQuesten Suite.
 
The Cougar showing lies on the northwest side of monument Hill. Contour sampling carried out in 2009 outlined a 250 m wide area containing strong gold (up to 123 ppm) and moderately anomalous bismuth (up to 123 ppm) values that correlate well with gold.  Prospecting carried out in 2010 located cobbles of dense rusty limonite with rare blebby bismuthinite and galena in quartz in a talus field comprised of mostly limestone flanked by volcaniclastic material to the east and west. Several samples collected from the area returned elevated gold (1.57 g/t and 3.13 g/t) values. Other samples returned bismuth values greater than 1%. Arsenic values throughout the showing are elevated and include peak values of 1.2 % and 2.1 %.  Other samples collected from the showing returned elevated lead values. One sample which returned 1.57 g/t gold also returned 19.4 % lead.
