Project Geology

Overview:

Regional geology in this area has been relatively sparse, and the current property-scale interpretation has been derived from mapping completed by James Smith in 1968 and published in 1977. The property geology is dominated by the Lower Jurassic Lower Hazelton Group andesitic to dacitic volcanics, volcaniclastics, and associated sedimentary rocks, trending broadly east-west across the property. Midway down the south face of the ridge towards the West Fork of Texas Creek, this Lower Hazelton volcanic package contacts with the coeval Texas Creek Stock, a granodiorite to quartz diorite to quartz monzonite. This Lower Hazelton package and coeval intrusive bodies are a regionally prospective stratigraphic horizon that plays host to most of the large high-grade gold and silver deposits in the Golden Triangle.

Of 31 samples collected historically by United States Federal Government geologists across the property, gold and silver values range from trace to 37.5 g/t Au and trace to 1,168 g/t Ag.  16 samples returned over 1.0 g/t Au, with individual samples including: 8.1 g/t Au and 742.6 g/t Ag, 6.8 g/t Au and 1,045 g/t Ag, 37.5 g/t Au and 56.9 g/t Ag, 15.4 g/t Au and 339.1 g/t Ag, 32.4 g/t Au and 62.7 g/t Ag; 24.7 g/t Au and 118.6 g/t Ag.  

Many historic prospects are encompassed by the Texas Creek claim group, dominantly located in the Lower Hazelton Group package proximal to the contact with the Texas Creek intrusive. Seven prospects of note include: Silver King, Solo, Blasher, Iron Cap, Homestake Mine, Double Anchor, and Silver Bell (see Figure).

Silver King:

The Silver King prospect is located on the west end and north slope of the ridge found immediately north of the West Fork of Texas Creek, sitting along the steep west-facing mountainside overlooking the Chickamin Glacier.  Polymetallic, mineralized quartz veining is exposed in two locations within greywacke and argillite of the Lower Hazelton Group, with footwall massive sulphide, dominated by galena with lesser pyrite, chalcopyrite, sphalerite, and tetrahedrite. Two grab samples returned 12.5 g/t Au and 604.1 g/t Ag as well as 14.6 g/t Au and 867.8 g/t Ag. A sample of the galena ore reportedly yielded 36.8 ppm gold, 207 ppm silver, 55.2% lead, and 2.2% copper. Historic gold values grade up to 14.6 g/t Au and historic silver values grade up to 868 g/t.

Solo:

Located along the western flank of the ridge found directly south of the Texas Creek Glacial Valley at 1524-meter elevation, the Solo Prospect/Mine consists of historic, sub-glacial workings in pelitic metasedimentary rocks of the Lower Jurassic Lower Hazelton Group. Miners tunneled 1800 meters of working under glacial ice to locate the source of high-grade galena-electrum stringers identified in boulders found on the slopes below the current workings. In 1937, a narrow, electrum-bearing vein was discovered and mined, reportedly producing 0.5 million tons of high-grade silver-gold ore. Significant melting of alpine glaciers in the region has occurred since this time, suggesting an abundance of new exposure in the Solo area since historic exploration occurred.  

Blasher:

Located 300 meters north-northwest of Texas Lake, the Blasher Prospect consists of a 3-meter wide, northwest-trending, moderately dipping fissured zone containing a 1.5-meter-wide, 45-meter-long polymetallic quartz vein and adjacent mineralized stringers. The showing is hosted in silicified pelitic metasedimentary rocks of the Lower Hazelton Group.  Documented workings consist of two 4 meter and 35-meter-long adits, surface cuts, trenches, and pits, along with seven exploratory drill holes.  A weighted average of samples taken along the exposed length of the vein yielded concentrations of 1.8 g/t gold, 254 g/t silver, 4.02% copper, and 2.74% lead. Gold values grade up to 5.0 g/t and silver values grade up to 500 g/t. 

Iron Cap:

The Iron Cap Prospect is located at an altitude of 1173 meters on a south-facing mountainside overlooking the West Fork of Texas Creek, roughly 3 kilometers east-northeast of the outlet of Texas Lake.  The prospect consists of a 3.5-meter-wide zone of polymetallic sulfide-bearing quartz-calcite veins and stringers hosted within fine-grained, pelitic metasediments of the Lower Hazelton Group.  The vein zone is exposed in a 3.5-meter-wide pit, with an east-northeast trike and a subvertical dip. Historic assays yield up to 1.3 g/t gold and 1297 g/t silver.

Homestake Mine:

The historic Homestake Mine is located 2 kilometers north of the West Fork Texas Creek, at an altitude of 1080 meters. 8 meters of addit have been driven to cut the vein. The host rock of the showing is the Texas Creek granodiorite. The vein trends northwest with a moderate northeast dip and has been traced 80 meters along strike, averaging a width of 1.5m. Mineralization is concentrated in a 45-meter-long blowout to the north. The vein is comprised of banded massive sulphide, dominated by ‘steel’ galena with lesser pyrite and chalcopyrite. Historic assays have returned gold values of up to 14.5 g/t.

Double Anchor:

The Double Anchor prospect is located at an altitude of 1220 meters, near the head of a steep gulch just due north of Texas Lake. The prospect consists of a shear zone and concordant breccia vein hosted in metasedimentary rocks of the Lower Hazelton Group.  The vein has been traced for a total length of 265 meters along strike and exhibits moderate gold, silver, zinc, and lead values. An 82-meter-long vein segment was assayed with an average of 0.5 g/t gold, 41 g/t silver, 1.5% lead, and 0.4% zinc over 37 centimeters. Historic assay values have yielded up to 36.8 g/t gold and 207 g/t silver.

Silver Bell:

Located in pelitic metasedimentary and subordinate andesitic metavolcanic rocks of the Lower Jurassic Hazelton Group, the Silver Bell showing is underlain and locally intruded by the Texas Creek stock. The prospect is comprised of polymetallic copper-lead-zinc quartz veins in a brecciated fissure zone striking east-west and dipping moderately to the north. The vein exposure trends for at least 15 meters along strike and is an average of 80cm wide. Sulphides are disseminated and local massive clots of galena. Historic assays included values of up to 942 g/t silver in grab samples.
