Staked within a large block of “T” claims (various claim numbers, T cl 802 = YD22932) 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. In 2012, silt and rock geochemistry was carried out over the occurrence area.
In 2013, the Zodiac occurrence was discovered through geochemical sampling and sampling was expanded in the area (prospecting, soil and silt). Excavator trenching and hand pitting was also completed on the occurrence in 2013.
A small prospecting program was completed in 2014 over the occurrence.
In 2017, one diamond drill hole was collared less than 200 m from the location of the occurrence.
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 Zodiac showing (occurrence location) is located proximal to a high angle fault which ATAC Resources named the Anubis fault. It separates Middle Devonian Limestone to the south from overlying Upper Devonian to Mississippian argillite to the north.
The Zodiac showing is located proximal to the Anubis fault within a strong mercury and thallium soil anomaly. Grab rock samples collected from outcrop and hand pits returned up to 1.03 g/t gold from gouge material overlying the fault. Additional samples collected from strongly silicified dolomitic limestone located within the corridor of the fault returned assays of up 519 g/t silver (15.14 oz/ton) 11.75 % lead and 16.00 % zinc.
