Nis and Sek Epithermal Gold Projects

The Nek and Sek property comprises150 mineral claims located in the Whitehorse Mining District of the Yukon Territory and cover a total area of 3135 hectares located 30 kilometers east of Solomon’s Rosie Gold Project,  a highly prospective gold target indicated by regional stream geochemical surveys and the discovery in 2010 by the Yukon Geological Survey of an outcrop of highly silicified altered quartz feldspar porphyry at the top of the Ruby Range batholith, likely the result of a high sulphidation epithermal system.

 

The Nis and Sek Claims are located approximately 105 kilometers north of the town of Haines Junction and approximately 20 kilometers west and northwest of the Aishihik Road.  The claims were staked in the course of a regional exploration project conducted by Solomon which focussed on epithermal gold targets in a poorly explored belt extending from the eastern headwaters of Dwarf Birch Creek to the eastern shore of Aishihik Lake.  The primary focus of the project was the upper reaches of the Ruby Range batholith and Rhyolite Creek Volcanic-Plutonic Complex extending east and west of the Rosie Claim Group.

Historical mineral occurrences in the surrounding area formerly thought to represent Casino-style copper-molybdenum-gold porphyry style mineralization are now believed to be epithermal occurrences associated with the upper-most and younger fractionated portion of the Ruby Range batholith. Historical regional aeromagnetic data and regional airborne magnetometer data released by  the Geological Survey of Canada in July of 2011 corroborates the prospective nature of these properties as do pronounced Bouguer Gravity Anomalies on the North Aishihik regional gravimetric survey released by the Yukon Geological Survey in May of 2011.  Historical regional stream sediment geochemistry data shows anomalous gold values coupled with one or more of copper, molybdenum, arsenic, mercury and antimony.

The geological setting of the Nis and Sek Claim Groups is poorly understood but fieldwork conducted early in the 2011 season shows that both properties include outcrop of the Rhyolite Creek volcano-plutonic complex,  the youngest porphyritic phase of the  Ruby Range batholith and its volcanic equivalents which locally consists of intermediate volcanic flows, breccia and tuff, flow-banded rhyolite and felsic tuff.  The Ruby Range Batholith underlies the west and central portion of  the Sek Claim Group and is locally composed of quartz diorite and granodiorite.

Geological Setting of Nis and Sek Claims.  The highly prospective Rhyolite Creek Volcano-Plutonic Complex is depicted in the buff coloured map unit surrounding the Rosie  Claim Group and is believed to extend 30 kilometers easterly to the Nis and Sek Claim Groups.

Recent work by the Yukon Geological Survey has drawn new attention to this area, and a significant increase in claim staking in this belt over the past few months suggests that companies looking to acquire new and prospective ground outside of the heavily staked Dawson Range and Selwyn Basin Gold Districts are turning their attention to the underexplored Ruby Range.

The Nis and Sek Claims are highly prospective for epithermal gold mineralization. Recent work by the Yukon Geological Survey has suggested a compelling similarity between the geological setting and mineralization potential of the Coast Belt in the Ruby Ranges and the Juneau Gold Belt.  The similarities between the two areas are striking, and mineralization seen to date in this portion of the Ruby Range have characteristics indicative of epithermal style mineralization.
