The Einarson project is a unique prospect in terms of both its scale and its world-class potential. It is a greenfield, district-sized property with multiple large targets and new gold discoveries analogous to Nevada's prolific Carlin Trend.
Project History
18526 Yukon Inc. began prospecting for Carlin-style gold in the Einarson area in 2008 with a small exploratory program, based on geological similarities between the Yukon's Selwyn Basin and Nevada's Carlin Trend. Prior to this work, the project area had seen only limited exploration for Mississippi Valley Type lead-zinc mineralization in the mid 1970s, and no exploration for gold.
Following the nearby discovery of Carlin-type gold in late 2010, 18526 Yukon Inc. began staking its highest priority prospects in the region. In early 2011, the company optioned the ground to Anthill Resources and expanded the claim position to roughly 2400km2. Anthill performed property-scale sampling and prospecting from 2011-2013, vectoring in on several areas and making two diamond drill gold discoveries, one on 18526 ground and another on Venus, an Anthill Resources target. No major exploration programs have been undertaken since 2013, leaving Einarson's large, promising gold discoveries untested and underexplored.
The project is now owned 70% by 18526 Yukon Inc. and 30% by Anthill Resources, with the smaller Venus in-holding owned 100% by Anthill Resources. The two companies seek to advance the district as a whole through third-party option, joint-venture or sale.
Geology & Mineralization
The Einarson project covers a sequence of upper Proterozoic to Paleozoic passive margin carbonates, debris flows, deep water siliciclastics, and volcanics. Units are generally flat-lying and cut by large, low-angle faults, though higher angle faults and areas of intense folding are also present and in cases appear important to mineralization.
Several styles of sediment-hosted gold have been discovered at Einarson, most notably Carlin-style gold at Venus, where native gold grains form on rims of arsenian pyrite around pyrite crystals. (An in-depth analysis of mineralization at Venus can be found in Nikolett Kovacs' BSc thesis, available from Memorial University here.) Drilling in 2012 returned a 38.7 m interval averaging 9.67 g/t gold, and grab samples of silicified carbonates on surface have assayed up to 191 g/t gold.
In the Mars zone, where a second drill discovery has been made, gold appears to be related to quartz along a major fault structure. Hand trenching across the trend averaged 1.83 g/t gold over 30 m. Only the extreme southern end of the 4 km Mars anomaly has been drill-tested (0.58 g/t over 21 m), as later soil sampling revealed the location of the main trend, with soil samples up to 8.97 g/t gold, farther to the northwest. A nearby 1.3 km long gold in soil anomaly, also untested, returned prospecting grab samples of up to 25.2 g/t gold.
Elsewhere on the project, multiple large gold and Carlin pathfinder (As-Sb-Hg-Tl) stream sediment and soil anomalies remain unexplained and largely untested. The longest forms a pronounced 26+ km linear trend of anomalous gold in soils that has yet to see drilling.
