Einarson

The Einarson property is located in the Yukon’s mineralogically fertile but underexplored Selwyn Basin. The property consists of two main claim blocks and several outlying claim groups covering a combined 61,690 hectares within a broader 60 x 52 kilometre region. Einarson encompasses multiple kilometres-scale geochemical anomalies associated with thrust-faulted domal uplifts of interbedded carbonate and siliciclastic stratigraphy prospective for Carlin-type gold deposits, as well as instances of structurally controlled quartz mineralization with grab samples grading up to 34.2 g/t Au. In contrast with the host geology of the adjacent Nadaleen trend’s Carlin-type deposits, discovered in 2010 by ATAC Resources Ltd. some 10 km from the northwest boundary of the present-day Einarson property, geological units at Einarson are relatively flat-lying, though structurally prepared at smaller scales through tectonic shortening.

Snowline benefits from the work of past operators Anthill Resources and 18526 Yukon Inc., who secured the large Einarson mineral tenure, collected more than 25,000 soil samples and 4,500 stream sediment samples on and around the property, conducted preliminary prospecting and geological mapping and performed limited drilling. This work revealed large gold and Carlin-pathfinder element (As-Sb-Hg-Tl) anomalies up to 30 kilometres in length and multiple new gold occurrences. The discoveries are entirely novel – prior to 2010, no exploration for gold is known to have occurred anywhere on or in the vicinity of the district- scale Einarson project.

Primary target areas include:

  • Mars NE – an orogenic gold target with abundant mineralized quartz float boulders grading to 25.2 g/t Au associated with zones of clay alteration in bedrock and a 3 kilometer zone of anomalous gold in soils to a maximum 5.3 g/t Au. Based on regional stratigraphy, carbonate units favourable for Carlin-type mineralization are expected to be present within several hundred metres of surface.
  • Avalanche Creek – an orogenic gold occurrence discovered in September 2020 along a major fault structure. 22 grab samples of a mineralized boulder train averaged 7.8 g/t Au and graded up to 34.2 g/t Au.
    Mars – an orogenic(?) gold occurrence with Carlin potential. Only the southernmost end of a 3.5 km gold in soil anomaly has been drilled, consistently yielding gold mineralization in silicified structural zones with intervals of up to 0.571 g/t Au over 21.16 meters (poor recovery). Surface channel sampling at this south end yielded an interval of 7.09 g/t Au across 5.0 metres within a broader 33.5 metres averaging 1.65 g/t Au. Elsewhere on the trend, soil samples grade up to 9.1 g/t Au. Favourable Carlin host units are present near surface and have not been drill tested.
  • Misty – a 30-kilometer-long zone of consistently elevated to anomalous gold and Carlin pathfinder elements in soils corresponding to a variably faulted, doubly plunging anticlinal structure exposing carbonate stratigraphy known elsewhere to host Carlin-type gold.
  • Odd – a pronounced 3.5-kilometer-long gold and Carlin pathfinder element soil and stream sediment anomaly corresponding to a thrust-faulted domal exposure of carbonate stratigraphy. Surface sampling and limited drilling have failed to explain the anomaly. Additional carbonate units favourable for Carlin-type mineralization expected at depth.

The Mars NE zone will be the initial focus of exploration efforts at Einarson during the 2021 field season, with additional geological mapping, soil sampling, prospecting and induced polarization geophysics planned prior to commencement of drilling in late June.

Snowline holds a majority 70% interest in 3,016 of 3,041 claims at Einarson, and 100% of the additional 25 claims. The remaining non-carried 30% interest is held by Anthill Resources, a private Vancouver, BC based company.

 

Geological setting - Einarson
Geological setting of the Einarson project, highlighting major structural features at a regional scale. The project is situated within a tectonostratigraphic block bound on the northeast by the Selwyn Valley thrust and on the southwest by the dextral Hess-Macmillan fault system. Tight, NW-SE trending fold axes near the Selwyn Valley thrust are wrapped in a broad drag fold (syncline) by motion along the Hess-Macmillan fault, as are the associated Arrowhead and Elmer Creek thrusts. At the apex of this fold, the sedimentary package is intruded by Cretaceous (red) members of the Tombstone plutonic suite (the targets of Snowline Gold Corp’s “Rogue” project). The tectonostratigraphic block also accommodates offset along the east-west trending Kathleen Lakes fault and Dawson thrust, which appear to horsetail into a series of district-scale folds NW-SE and N-S folds within and around the Einarson property, and may be important controls to mineralization.

 

Not all previous work at Rogue and Einarson nor samples from either property have been verified by the Company, and readers are cautioned not to place undue weight on such results. Highlighted samples are selected from a larger population of samples and are not indicative of the average grade of mineralization hosted on either property. Both properties are early-stage exploration properties without established mineral resources, and no guarantee can be made at this time that economically viable mineral resources are present. As such, the projects represent a high degree of risk.
