Gold wurde gefunden!
2019 drilling program tested several distinct targets within four target areas at Keystone, including the first ever test of the Nina Skarn target area, where the thickest intervals of strong, continuous gold mineralization ever drilled at Keystone have been encountered. The key geological features of the hole indicate it intersected the halo of a large gold system.
The drilling program also encountered anomalous gold and strong concentrations of pathfinders, with numerous holes intersecting significant gold assay intervals greater than 0.300 gpt (see results tables below), confirming the belief of U.S. Gold Corp. that Keystone is a stand-alone domal district, with the potential for multiple high-grade gold deposits.
ELKO, Nevada, November 12, 2019 /PRNewswire/ -- U.S. Gold Corp. (NASDAQ: USAU), a gold exploration and development company, is pleased to announce results of its 2019 drilling program and receipt of drill-hole assays from the Keystone project, located on Nevada's Cortez Trend. This program comprised of six reverse circulation holes, and one core hole that further explores the encouraging results from the 2018 Key18-09rc drill hole. The seven holes comprise a total of 13,177 feet (4,016 m), testing specific drill targets within the Sophia, Tip Top, Sophia South and Nina Skarn target areas detailed on the following map: https://www.usgoldcorp.gold/properties/keystone/2019-phase-one-map Five of the seven holes intersected significant gold assays, highlighted by the Key19-05rc drill hole, the first ever drill-hole test of the Nina Skarn target, a +700m long coincident gold-bismuth-tellurium rock and soil anomaly defined in 2018 by surface sampling. The Key19-05rc drill hole encountered two thick intervals of strong, mostly oxide gold mineralization: 67.06m of 0.194 gpt from 12.2m and 76.2m of 0.224 gpt from 150.9m (see link below for photo of exploration activity). These encouraging results further affirm the potential for large gold systems at Keystone, with similar potential for the neighboring Cortez Hills district. https://www.usgoldcorp.gold/properties/keystone/key19-05rc Of note, anomalous gold mineralization is present throughout the entire thickness of skarn altered Upper and Lower Plate rocks drilled, from surface to 414.5m. Cyanide solubility assays were run on selected intervals and demonstrate as much as 90% of the contained gold is cyanide soluble within one hour, suggesting this style of mineralization is amenable to cyanide extraction. Detailed intercepts for Key19-05rc are identified below in Table 1. The entire assay sequence of the Key19-05rc drill hole, including visual metallurgical and cyanide soluble characteristics, is illustrates grade continuity and can be found in the link below (Figure 1: Key19-05rc Gold Assays and Metallurgical Characteristics), along with a cross section of the drill-hole (Figure 2: Key19-05rc Cross-section). True thicknesses are unknown at this time. The encouraging results support future testing to explore upon the mineralization encountered in Key19-05rc along the +700m Nina Skarn anomaly, with overall additional potential for 2km strike-length along the Walti stock contact. To the north of Nina Skarn, near the old Keystone mine, rock chip samples of skarn with +27 gpt Au assays are present, and to the south of Key19-05rc, 6m of 1.13 gpt Au was encountered last year in Key18-09rc, hosted in Comus skarn. Figure 3 below, Gold Skarn Potential Areas of Keystone, illustrates these findings and the surface Au-Bi-Te anomalies relative to the Key19-05rc drill hole (Figure 3.).
