Aurion Receives Key Permits At Logan Pass
NEWFOUNDLAND - Aurion Resources Ltd. has received The U.S. Bureau of Land Management's ("BLM") Record of Decision confirming approval for a Plan of Operations for its Logan Pass carlin-type gold project in Nevada. The approved Plan of Operations allows Aurion up to 50 acres for exploration and development drilling in two primary target areas within its core group of claims.
The Main Jasperoid, is a Carlin-style gold prospect characterized by oxide gold mineralization in altered and silicified silty Carbonate rocks of the Pogonip Group. This prospect was outlined over an area of approximately 450 m (NW-SE) by 150 m in the early 1990's by surface sampling and limited RC drilling. Chip-channel samples collected by Aurion at the Main Jasperoid area yielded from below detection to 13.5 g/t Au over 2.0 m, and 7.2 g/t Au over 5.8 m. All samples had elevated Carlin-style As-Sb-Hg-Tl geochemistry.
The best reported historic drill intersections at the Main Jasperoid include 2.3 g/t Au over 7.6 m, starting at 5 m below surface and 1.5 g/t Au over 9.2 m starting at 7 m below surface. Two holes drilled at that time approximately 185 m SE and 250 m S of the Main Jasperoid intersected oxide gold mineralization assaying 0.5 g/t Au over 13.7 m and 0.6 g/t Au over 12.2 m respectively. The shallowly dipping mineralization is open to the south and east but appears to be fault-offset (down-dropped) to the west where it is a buried target. IP and CSAMT geophysics indicates a potential feeder structure at depth to the surface mineralization. The surface projection of this "feeder" structure parallels the western boundary of the mineralized jasperoids.
The Southpaw prospect, located 6 km NNE of the Main Jasperoid, hosts high grade gold mineralization over an area of 250 m (NW-SE) by 225 m (E-W) within jasperoid and jasperoid breccias along steeply dipping structures and bedding-parallel replacement lenses associated with manganese, silica and carbonate alteration within carbonates at the contact with the underlying Eureka Quartzite. The Southpaw prospect was mined for manganese (Mn) in the 1950's and grab samples by Aurion assayed from below detection to 19.3 g/t Au and 831 g/t Ag in this area. Chip/channel sample results include assays from below detection to 3.7 g/t Au over 1.0 m, and 2.6 g/t Au and 154 g/t Ag over 4.0 m. The average of 23 samples was 1.2 g/t Au and 183 g/t Ag over an average width of 1.3 m. All the samples yielded elevated Carlin-style As-Sb-Hg-Tl geochemistry.
Aurion believes this widespread hydrothermal manganese and jasperoid development with associated gold mineralization may indicate a deeper, potentially richer source hosted within Pogonip carbonates beneath the overlying quartzite.
At its Bull Gold Project, which is also prospective for Carlin-type deposits, is located on the southern part of the Battle Mountain-Eureka Trend. Previous workers in limited drilling in 1994 intercepted 3 m of 2.05 g/t Au within a 9.15 m intercept grading 1.15 g/t Au starting at approximately 15 m below the surface. Airborne geophysics (ZTEM/Mag), mapping, prospecting, geochemical sampling and compilation by Aurion, linked the mineralized outcrops with the extension of the controlling structure of Midway's Goldrock deposit to the south, and nearing production.
The Bull property is optioned to Midway Gold Inc., who can earn a 50% interest by expending US$2 million by Nov 2016. They can earn an aggregate of 70% by spending an additional US$2 million.
