The Texas Creek property is a 1498-hectare claim block comprised of 185 claims (see Figure 1). The property is located 19 kilometers northwest of Hyder, AK and 9 kilometers west of the past-producing Premier Gold Mine. Blackwolf Copper and Gold acquired 100% interest in this property through physical staking in May and June of 2021.
The Texas Creek property is bounded to the west by the Misty Fjord National Monument, and to the north by the Alaska-Canada border. The West Fork of Texas Creek lies to the south, the Texas Glacier to the North, and the Chickamin Glacier to the west. The property contains multiple known mineral occurrences, including historic prospects and small-scale past-producing gold and silver mines. These prospects are hosted within the same Lower Jurassic Hazelton Group stratigraphic horizon that plays host to the majority of large high-grade gold and silver deposits in the Golden Triangle.
Very little exploration has been completed on the property, with virtually none in the past 25 years. During the 1920’s, a trail was built on the north side of the West Fork of Texas Creek, which opened the area to prospecting. In the 1920’s and 1930’s, Blasher, Double Anchor, Ibex, Homestake, Silver Bell, Silver King, Silver Coin, Silver Star, Lake, and Morning Star prospects were discovered. Exploration occurred through to the 1950’s. Sampling was completed in and around pits, trenches, and short adits spanning a seven-kilometer area north across the Texas Creek property.
In 1925, high-grade galena-electrum float was discovered, leading to the discovery of the Solo prospect in 1930 by tracing this float to the nose of a glacier. By 1937, 1800 m of tunnels had been developed under the ice, and 32 kilograms of high-grade ore were mined and milled from a high-grade galena-electrum vein. An additional 0.5mt of high-grade ore were shipped to the Tacoma smelter.
In the 1970’s, the El Paso Natural Gas Company conducted minor drilling at the Solo Prospect, of which the results are unknown. From 1989 to 1991, Hyder Gold Inc. examined the Double Anchor, Dog Hole, and Iron cap locations. The area also received attention from the U.S. Bureau of Mines between 1972-1973 and 1992-1993 who conducted limited mapping and sampling of several historic prospects on the property. Exploration by Blackwolf to date has focused on the Solo and Doghole prospects and has included geologic mapping, rock sampling, LiDAR, and remote sensing surveys.
The Solo prospect is located on the western flank of the Texas Creek property and is dominated by quartz-vein hosted massive galena-pyrite-electrum mineralization in Lower Jurassic Lower Hazelton argillitic sediments. In the 1930’s, miners built 1,800 meters of tunnels through an ice sheet chasing source of the electrum, including a glacial transported float that assayed over 20,000 g/t Au. Significant glacial recession has occurred since, however large areas of snowpack did not melt during the summer of 2021 or 2022, including the estimated location of one of these veins in outcrop. Intrusive rocks and very high-grade, late tension veins are similar to those observed at the Premier and Brucejack deposits in the Golden Triangle and suggest potential for a strong mineralizing system. 2021 samples at the Solo prospect returned up to 20.6 g/t Au, 386 g/t Ag, 26.5% Pb and 10.9% Zn in one of these veins. Highlights of the 2022 sampling at Solo include(1):
- C0042635: 20.6 g/t Au, 386 g/t Ag, 1.47% Cu, 26.5% Pb, 10.9% Zn;
- B0011001: 7.23 g/t Au, 175 g/t Ag, 0.15% Cu, 13.6% Pb, 8.62% Zn;
- B983870: 8.49 g/t Au, 315 g/t Ag, 0.59% Cu, 18.5% Pb, 0.54% Zn and;
- B0010866: 6.04 g/t Au, 3836 g/t Ag, 0.9% Cu, 3.47% Pb, 2.1% Zn.
Located on the Texas Creek property, Doghole consists of shear-hosted sulfide mineralization along with proximal intrusion-related semi-massive to massive sulphide mineralization set in sills, ranging from five to twenty meters wide, of the Early Jurassic Texas Creek granodiorite. These sills are cross-cut by late, continuous quartz-sulphide epithermal-style veins. Samples from the 2021 program returned up to 11.3 g/t Au, 530 g/t Ag, 0.44% Cu and 4.63% Zn, and were focused on historic workings on the target(2). Sampling in 2022 followed on the 2021 program and traced a series of NE trending quartz-sulfide veins over 220m along strike. A total of 15 samples were taken along the trend and returned 0.92 – 16.6 g/t Au, averaging 6.02 g/t Au. Individual highlights of the 2022 sampling at Doghole include(1):
- B0010766: 16.6 g/t Au, 585 g/t Ag, 0.13% Cu, 1.52% Pb, 3.32% Zn;
- B0010759: 12 g/t Au, 85.3 g/t Ag, 0.17% Cu, 1.13% Pb, 0.29% Zn;
- B0010762: 7.94 g/t Au, 642 g/t Ag, 0.59% Cu, 11.3% Pb, 6.64% Zn and;
- B0010755: 8.17 g/t Au, 292 g/t Ag, 0.55% Cu, 4.82% Pb, 0.17% Zn.
