ELKO, Nev., Feb. 13, 2018 /PRNewswire/ -- U.S. Gold Corp. (NASDAQ: USAU) today announced completion of the Fall 2017 drilling program and receipt of all certified assay results. The primary purpose of this scout hole program was to obtain more information about important host rock characteristics including, presence, distribution, depth, and the hydrothermal system presence and alteration effects on the rocks. This program was comprised of eight widely-spaced reverse circulation drill holes, including one hole at Gold Bar North. The eight holes comprise a total of 14,720 feet (4487 m). Historically, Keystone had not received any systematic, modern day exploration assessments and very little was known about this important district-scale project.
Highlights of this program are;
- Drilling has established that Keystone host rocks are the same as, or very similar to, the units that comprise the primary host units within the Cortex District to the north. In addition, U.S. Gold Corp.'s geological studies have demonstrated the presence of a very complex, early-Tertiary intrusive/extrusive magmatic setting. Prospective host rocks at Keystone include the Horse Canyon, Wenban, and upper Roberts Mountains Formations of Devonian age, and the lower Silurian age Roberts Mountains Formation - comprising a total host unit thickness greater than 2000 feet. These units are showing to be variably exposed at the surface and, or at generally shallow depths in the District.
- The scout hole program also shows that multiple, Carlin-type gold deposit target settings are present within the twenty square mile area Keystone District, which is entirely controlled by U.S. Gold Corp. These targets are now being further synthesized using in-house detailed gravity data, ongoing geologic mapping, and new surface geochemistry combined with historic exploration data.
- Both core and reverse circulation drilling has been conducted through 2017 to gain better understanding of the host unit characteristics, the prospective depths that gold deposits are likely to occur, and to provide an early-stage, and broad geographic assessment of an apparent very large, Carlin-type, district-scale gold system. Almost all holes drilled to date have encountered thick zones of anomalous gold and locally very strong associated pathfinder arsenic, antimony, mercury and zinc. Some holes have also intersected thin zones of economic levels of gold, see Table 1.
- The Keystone District is located along the southeast extension of the Pipeline-Cortez District corridor as confirmed by the presence of an early-Tertiary complex intrusive center, the presence of permissive, Paleozoic transitional carbonate rocks, the presence of a strong north-northwest-trending gravity and magnetic linear, and the spatially coincident Strontium 86/87 (.706) data indicative of an oceanic crustal source for gold.
Dave Mathewson, Vice President, Head of Exploration, states: "I am very pleased with the important, exploration-applicable information that we have obtained from the drilling programs to date. All the Fall 2017 holes intersected thick intervals of anomalous gold mineralization and associated pathfinder elements of arsenic, antimony, mercury and zinc. Arsenic, the element that gold is most strongly associated with is locally visible as arsenopyrite, realgar and orpiment, and is also locally very strongly geochemically present. This information all combines to qualify our assessment that we are in a world-class setting for very large gold deposits."
"Throughout the 2017 field season, our geological team has mapped the entire district/property position in detail and, also very importantly, has considerably added to the surface geochemical database with both additional detailed sampling and broader geographic coverage."
Dave Mathewson further states: "With all the new information in hand, the exploration team is now in the process of, and in the position to zero in on the many site-specific target opportunities that have emerged from the drilling that we have conducted to date combined with the recently obtained and assessed geochemical data. The key to ultimate success in the hunt for gold in Nevada is to locate and qualify the gold-bearing fluid conduits that have supplied the gold to the gold-bearing mineral system that is clearly in evidence in the case of Keystone. Once targets are identified and qualified, drilling becomes a vectoring process of drilling holes into these structural gold-bearing conduits and locating more specifically where the conduits cross-cut permissive host rocks. To this point in time in the Keystone exploration program, limited drilling access has been an issue because of limits on road and drill site surface disturbance. In preparation for this year's drilling program, a year specifically designed for more focused target testing and associated follow-up gold deposit definition, we are also about to complete an EA (Environmental Assessment) for the purpose of significantly expanding access with a drilling POO (Plan of Operations). We expect to commence specific-site target drilling as soon as 2018 field conditions allow."
Edward Karr, President and CEO of U.S. Gold Corp., stated, "We continue to be excited by the extensively thick, permissive host rock packages that we have encountered at Keystone. The Fall drill program marks the completion of our early-stage, systematic exploration work at the project. This also coincides with the near completion of our EA, which will ensure an uninhibited drill program in 2018, and the closing of our recent $5 million financing. U.S. Gold Corp. is well financed and strongly positioned to make a significant discovery this year at Keystone."
