Outcropping gold-bearing jasperoids in the Carlin Trend
Located in Nevada
Carlin-type gold mineralization hosted along the Mississippian/Devonian unconformity.
The Diamond Point Project is located in the prolific Carlin Trend in Nevada approximately 35 kilometers (22 miles) southeast of Gold Standard Ventures evolving Railroad-Pinion district and 26 kilometers (16 miles) northwest of Kinross Gold's Bald Mountain district.
The Diamond Point project area has seen fairly limited historic exploration. The first phase of exploration was completed by MK Gold in the late 1990's and included 3,074 meters (10,085 feet) of RC drilling on outcropping gold-bearing jasperoids. Sixty-eight 1.5 meter (5 foot) intervals in the MK drill program exceeded 0.100 g/t. The best intercept in the program was 1.5 meters of 2.3 g/t Au along with 2960 ppm As within a larger interval of 12.2 meters of 0.3 g/t Au. Max Resource Corp. in joint venture with Kokanee Resources completed two core holes totaling 160 meters (525 feet), offsetting mineralization intercepted in the MK Gold drill program. The best intercept reported by Max Resources was 7.6 meters of 0.59 g/t Au. Anglo Gold completed CSAMT surveys across the pediment to the north of the outcropping jasperoids and drilled 3 widely spaced holes totaling 693 meters (2,275 feet). Anglo did not intercept significant gold mineralization, but their drill data are used in conjunction with the CSAMT data to define the projection of the mineralized fault zone. Kinross Gold U.S.A joint ventured the project in 2017 and drilled 1200 meters (3,940 feet) of RC drilling in 6 holes. The Kinross program was a scout drilling campaign targeting open pit mineable mineralization in the pediment northwest of Diamond Point. The best intercept from that campaign was 5 feet of 0.291 g/t Au in the West Fault zone. Previous drilling is historic in nature and has not been verified by Orogen’s qualified person (QP).
The Diamond Point project covers a zone of gold-bearing jasperoids that occur in the Mississippian Diamond Peak and Chainman Shale stratigraphic units. Two steeply west-dipping subparallel normal faults, the East and West faults, lying about 130 m apart control the gold mineralization in the area. These faults occur between two mapped synforms and are interpreted to represent a ruptured antiform pair. The south end of the structural zone is a Tertiary intrusive center with associated weak polymetallic carbonate replacement mineralization and skarn development. Multiple Tertiary dikes are mapped striking north-northeast into the covered pediment target. The primary target on the project is intersection of these mineralized fault zones with favorable host stratigraphy at the Devonian unconformity.
Outcropping gold mineralization along the West Fault occurs in jasperoids. Sixteen rock chip samples taken by Orogen returned Au values ranging from 6.7 g/t (6700 ppb) to below detection limit,
