Castile Mountain Project

The Castile Mountain gold prospect is a shallow low sulfidation epithermal target located in the Tuscarora Mountains of north-central Nevada, about 3.5 miles southwest of the productive vein systems at Tuscarora. The property consists of 8 unpatented lode mining claims sitting at the top of Castile Mountain.

The Rock Creek, Divide Mine, and Castile Mountain properties are all in the Tuscarora Mountains, which host the northern end of Carlin-trend mineralization. Northern Nevada more broadly represents one of the largest gold regions in the world, and hosts many “world class” gold mines including Gold Quarry, Goldstrike, and Betze-Post. The nearby town of Elko is the hub for many gold mines and exploration ventures, and can accommodate logistical needs.

Shell Mining drilled 5 shallow test holes in the area in 1984, with one of the holes drilled at the top of Castile Mountain. DH CM-1 encountered a mineralized zone that carried anomalous gold values ranging from 240 ppb to 400 ppb over 35 feet. Three intervals of unknown depths were reported:

20’@0.35 ppm Au
5’@0.4 ppm Au
10’@0.2 ppm Au

The Castile Mountain sampling program to date consisted of nineteen chip and grab samples from silicified volcanic rocks and paleo sinter outcrops and subcrops across the property.

  • Of the nineteen samples collected, nine samples yielded gold values greater than 0.1 g/t, with two samples containing more than 0.5 g/t (1.085 g/t and 0.633 g/t Au).
  • The samples also contained strong anomalies in pathfinder elements, including As values up to 2170 ppm and Ba values up to 650 ppm.

The Castle Mountain prospect is a low sulfidation epithermal gold target with strong surface alteration.  A paleo hot spring vent crops out at the top of Castle Mountain evidenced by a small area of sinter and silicified volcaniclastic rocks that carry anomalous gold.   The surrounding area features strong argillic alteration with minor quartz stock-work veins.

Surface mineralization is hosted dense welded andesite breccia (mapped as debris flow breccia) having a maximum thickness of 170 meters.  A lens of Paleozoic debris is interstratified with the andesite breccia.  Below that, Tertiary andesite, ash flow tuff and a basal conglomerate sit unconformably on Paleozoic sediments.  The estimated depth to the unconformity, based on a NBMG section drawn 2 miles to the southwest, is between 250m and 350m.  This unconformity represents an excellent stratigraphic target for mineralization below the hot springs vent.

The Gravel Creek project in northern Elko County is the best analog for Castle Mountain. Gravel Creek is a new gold/silver discovery by Western Exploration.  They have intercepts up to 16 meters long at 49 g/t Au, or up to 318 meters at 1.27 g/t Au.  Mineralization at Gravel Creek there is hosted in silicified breccia formed at the basement/Miocene interface below a surface sinter and weak geochemical anomalies (Christensen, 2015). The host rocks at Castle Mountain are of similar age and lithology.
