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 Panther 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.
 
ATAC Resources carried out prospecting and rock geochemistry on the Panther occurrence in 2015 as well as in 2018.
 
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 Panther showing, discovered in 2008 is located approximately 2.5 km to the northwest of the Tiger deposit. Prospecting located a north-northeast trending recessive linear that marks the contact between limestone to the south and volcaniclastic to the north. Samples of limonite float returned anomalous values for silver, arsenic, bismuth, lead, zinc and tungsten. ATAC Resources tested the down dip extension of the mineralization in 2008 with 2 diamond drill holes (244.25 m). The first hole was lost while the second hole intersected brecciated limestone containing calcite veins and a narrow volcaniclastic interval. No significant mineralization was encountered.

A specimen collected from this area in 2017 returned 8.18 g/t Au, 16.1 g/t Ag, 199.5 ppm Bi, 295 ppm lead and 857 ppm Zn. Additional Limonitic float was also found uphill, to the west but to date, the source of mineralization has not yet been located. Results of limited prospecting in the Panther area conducted in 2018 included a sample returning 4.61 g/t Au northeast of the main showing.
