Aurex Property

Location Map

The Aurex property is located with the Mayo Mining District, 56 kilometres northeast of Mayo. The claims are accessible via the Silver Trail Highway and 4-wheel drive road along Corkery Creek.

Target Deposit Type



Large-tonnage reduced intrusion-related gold systems associated with Cretaceous Tombstone and Mayo suite granodiorite intrusions and structurally-controlled high-grade gold-sulfide veins.

Project Summary



Aurex is a drill-ready project located approximately 50 km by road south east of Eagle. Access to the property is by road along the Silver Trail Highway, and by 4WD track. Historic drilling, predominantly focused at Aurex Hill, has returned several thick, low-grade intervals and grab samples from the Corkery Creek and ASPY showings have returned assays up to 30.3 g/t Au (Pautler, 2012; Wengzynowski, 2000). A VLFEM survey conducted on the property in 2011 identified several magnetic lows that may correlate to buried intrusions, and mapping during the 2012 field season identified zones of endoskarn (indicative of intrusive bodies) and outcropping mineralization. Anomalous W and Cu surface geochemistry at Aurex Hill also suggests the possibility of a buried intrusion. Aurex is considered highly prospective for Eagle-type intrusion related gold systems targets, and given its location proximal to Eagle a discovery could add significant value to the company.

Geology and Mineralization



Figure 1

The Aurex claims are predominantly underlain by metasedimentary rocks of the Hyland Group, which comprises a turbidite sequence of coarse-grained quartzite and quartz pebble conglomerate with minor interbedded siltstone and shale. Keno Hill quartzite and Earn Group schist and phyllite are interpreted to underlie the northwest corner of the claims. Results of a VLFEM survey conducted in 2011 and an earlier airborne electromagnetic survey indicate several magnetic lows on the property, suggesting the presence of buried intrusions in the Aurex North and ASPY showing areas. Previous exploration has also delineated areas of endoskarn at Aurex North, and anomalous tungsten and copper in soils at Aurex Hill, both of which indicate the presence of underlying intrusions (figure 1).

Mineralization at Aurex identified to date is predominantly hosted in quartzite and phyllite in quartz-arsenopyrite±pyrrhotite±pyrite veins. Veins typically cross-cut foliation but may also be foliaform. Higher grade mineralization identified during the 2012 field season was generally associated with linonitic quartz-breccias and scorodite-arsenopyrite veins, which also contained minor stibnite. Disseminated mineralization has also been recognized, as has skarn-hosted mineralization and visible gold in interpreted syn-deformation quartz veins in phyllite (Hladky, 2003).

Exploration



In July 2012 Yukon prospector Jean Pautler conducted a five-day reconnaissance evaluation of the property, collecting samples to confirm historical reports of gold mineralization at the main prospect areas on the property. Her work delineated several high-priority RIRGS targets based on coincident geophysical anomalies, Au, As and W in soils, outcropping endoskarn and Au-bearing quartz-arsenopyrite-scorodite±stibnite float. Six thousand metres of diamond drilling is proposed for Aurex to test down-dip and along-strike continuity of previously identified mineralization in historic drill holes at Aurex Hill, subsurface projections of endoskarn and magnetic lows identified by geophysics at Aurex North and high-grade mineralization associated with a magnetic low at Corkery Creek and ASPY showing. A number of conceptual targets coinciding with interpreted fault intersections are also slated to be tested for structurally-hosted and intrusion-related gold.
