Work History

Staked within a large block of “T” claims (various claim numbers, T cl 74 =YD22878) in Mar/2010 by ATAC Resources Ltd. The claims cover open ground that existed between the Dale claims to the north and Sten claims to the south staked in 2009.

In Jun/2010 the company flew an airborne ZTEM geophysical survey over eastern end of the larger Rau Gold Belt, which this occurrence lies within. In 2011 ATAC Resources carried out remote sensing studies over the entire Nadaleen trend and carried out extensive regional silt and soil sampling surveys over the Anubis occurrence area (Minfile Occurrence 106C 099) located approximately 1.4 km southeast. In 2012 the company carried out follow-up silt, soil and rock sampling programs over the Anubis occurrence area, prospected and hand trenched favorable areas.

In 2013 the company extended grid soil sampling to the south and northwest, in an area now known as the “Anubis cluster”. Following the receipt of geochemical results the company prospected, hand pitted, excavator trenched and rock sampled favorable areas which led to the discovery of the Draco showing. The company also tested the Draco showing with numerous excavator pits.  In 2014 ATAC Resources dug two excavator trenches each Draco showing.

Geology

The occurrence area is located in east-central Yukon within an area geologists have referred to as the Rackla belt. The Rackla belt straddles the northern edge of the Selwyn basin, where Neoproterozoic to Paleozoic rocks of the basin are juxtaposed against Paleozoic and older slope and basin rocks of the Ogilvie platform along the Dawson thrust zone. Selwyn basin rocks in the occurrence area are dominated by slope and facies carbonate, clastic rocks and siltstone with significant deep water black shale and chert, whereas the Ogilvie platform is dominated by shallow water platformal carbonate.
 
Based on geological mapping by Colpron et al. and geologists employed by ATAC Resources the occurrence area is underlain by a sequence of off-shelf carbonate and shale rocks of Middle Devonian (Eifelian) to Upper Devonian – Lower Mississippian age that are cut by a series of regional faults. The Draco showing (occurrence location) is underlain by Middle Devonian limestone which is separated by a high angle fault which ATAC Resources has named the Anubis fault, from overlying Upper Devonian to Mississippian argillite.

The Draco showing is located south of the Anubis fault and within a moderate silver, mercury and thallium soil geochemical anomaly. Excavator pits were dug along two roughly parallel north-northeast orientated lines orientated perpendicular to the Anubis fault. These pits intersected variably dolomitized limestone, moderately clay altered and containing thin horizons of arsenic-antimony-iron oxide.  Rock samples collected from the bottom of one pit returned gold values ranging from 1.04 to 1.57 g/t gold. A second series of pits dug approximately 350 m to the northeast to test a gold soil anomaly did not return significant gold mineralization. Additional trenching conducted in 2014 did not return any significant gold values but did return elevated values for pathfinder elements.
