WORK HISTORY
 
Staked as Black cl 1-6 (Y7495) and cl 7-32 (YA13001) and Ida cl 1-32 (YA13027) in Oct/76 by G. Bleiler and others. Later in the month M. Bratlien tied on Red cl 1-4 (YA13363) on the northeast boundary of the Ida claims. The occurrence is located within the Ida claims.
 
In Aug/77 Dejour Mines Ltd and Nova-Co Explorations Ltd optioned the Black and Ida claims from Bleiler and others. In Sep/77 the companies carried out large scale grid soil sampling and reconnaissance scale silt sampling across the claims and optioned the Glen claims.
 
Restaked within a large block of T claims (#3005 = YD33035) in Mar/2010 by ATAC Resources Ltd. The company flew airborne geophysical surveys across the entire Nadaleen Trend in 2010. 

The company staked IS cl 1-28 (YC99751) to the south and east in Oct/2010. In 2011 the company carried out regional silt sampling and contour and ridge and spur soil sampling programs in the vicinity of the occurrence. The company also flew LIDAR over the entire Nadaleen Trend in 2011. In 2012 ATAC Resources carried out additional regional soil and silt surveys throughout the area.
 
In 2013 ATAC Resources prospected the various “N” targets (near Ida area) to try and determine their source. No further work has been completed on 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.
 
Geological mapping carried out by Colpron et al. shows that the occurrence area lies within an uplifted wedge of rocks located in the foot wall of the Dawson Thrust. The occurrence is likely underlain by shales (unit PCHn) assigned to Neoproterozoic (Ediacaran) to Lower Cambrian Hyland Group Narchilla Formation which sandwiches a band of slightly older (unit PHa) carbonate rocks assigned to Neoproterozoic (Ediacaran) Hyland Group Algae Formation. A band of middle Devonian limestone (unit mDc) lies to the south where it is truncated by the Dawson Thrust. The entire sequence of rocks is thrust northeast against younger carbonate and clastic rocks. 

Silt and soil sampling programs outlined numerous moderate zinc +/- silver soil anomalies on the Black, Ida and Eira claim blocks. On the Eira claims soil sampling outlined an area of anomalous silver (up to 2.4 ppm) and zinc (up to 680 ppm) in the northeast end of the claim group. This anomaly is located approximately 10 km to the east of the current occurrence location. The original occurrence location appears to represent a 17 200 ppm zinc silt anomaly. The current occurrence location represents the approximate mid-point of the largest zinc anomaly discovered in the late 1970’s. The anomaly measures approximately 625 m long by 125 m wide and returned values up to 2 700 ppm zinc. Soil sampling on the Black claims returned several single station zinc anomalies.

The occurrence location lies on the outer edge of target “N2”, which is described as a 3 000 m long by 500 m wide arsenic and thallium soil anomaly. A second target “N9” is located approximately 5 km to the southeast. The target consists of 1 300 m long by 800 m wide arsenic and mercury soil anomaly.
