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 reconnaissance silt sampling and flew a helicopter-borne magnetic and variable-time domain electromagnetic survey over the newly staked area which included the Cheetah occurrence.
 
In 2009 ATAC Resources carried out grid and contour soil sampling followed by prospecting and rock sampling of anomalous areas including the cheetah 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. In conjunction with a property wide drill program ATAC Resources collared 6 diamond drill holes (945.82 m) on the Cheetah showing and completed soil sampling.
 
In 2011 the company carried out limited grid, ridge and contour soil sampling programs and collared 3 diamond drill holes (483.11 m) on the Cheetah showing. In 2012, ATAC carried out soil sampling over the occurrence area.
 
ATAC Resources performed prospecting and rock geochemistry in 2015 and 2017.
 
Regional & Property 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.

Mineralization & Results

The Cheetah showing, discovered in 2009, is located approximately 4 km northwest of the Tiger deposit and consists of a 500 m long by 400 m wide float train predominantly composed of goethite and limonite float. The float train is cut by a prominent linear. A sample of a purple brown, goethite rich boxwork limonite returned 3.06 g/t gold while all other samples contained less than 0.24 g/t gold. A 10 m trench dug in 2009 approximately 50 m downhill from the float train did not expose any mineralization and samples collected within the trench returned only background values for all elements. In 2010 ATAC Resources tested a portion of the linear corresponding to a 310 m long string of anomalous soil samples with 6 diamond drill holes (945.82 m). The best intersection was obtained from drill hole CH-10-04 which returned 1.29 g/t gold over 16.90 m. In 2011 three holes were drilled and intersected intensely oxidized intervals within the dolomite. The oxidized intervals had an average width of 25 m with a composition ranging from partially oxidized dolomite to limonite rich mud. The most significant intersection from drilling was from hole CH-11-07 which graded 1.11 g/t gold over 13.72 m. In 2017, prospecting was conducted along float trains and northeasterly-trending structures. An oxide float sample collected during this program returned 2.00 g/t gold and 1.29% zinc (see ATAC Resources news release: 6 Feb/2018).
