Carlin Reports on Cortez Summit Drilling
VANCOUVER, BC - Carlin Gold Corporation reported that it has completed a limited core drilling program on its Cortez Summit property ("Cortez Summit" or the "Property"), Eureka County, Nevada. The program consisted of entering and deepening one of the reverse circulation holes completed in 2012 on the west side of the Property and successfully established the presence of deeper, favorable 'Lower Plate' carbonate rocks within a prospective structural setting. Lower Plate rocks host the bulk of the gold mineralization in the Cortez district.
In September 2013 the Company re-entered vertical reverse circulation hole CS12-2 and deepened it from 1,760 ft. to 4,032 ft. Drilling was completed on October 25, 2013. Short intervals of anomalous gold values to 0.667 grams/tone and Carlin-type pathfinder elements were encountered, as well as longer intervals of anomalous arsenic values (greater than 100 ppm) ranging up to 130 ft. of drilled thickness. The bottom 900 feet consisted of variably calcareous mudstone/sandstone, and silty/sandy, laminated, variably carbonaceous limestone. This material locally displays Carlin-type alteration features such as decalcification, clay alteration and calcite veining. Carlin geologists are encouraged that favorable Lower Plate carbonate rocks are present near the projection of the gold-bearing Fourmile structural corridor, at depths consistent with some of the holes in the north portion of Barrick Gold Corporation's neighboring Goldrush discovery.
The Company's initial drill program in 2012 consisted of seven vertical reverse circulation holes totaling 11,720 feet ranging in depth between 1500 and 1800 feet. All holes encountered Paleozoic sedimentary rocks, which are now considered to be structurally and stratigraphically above the calcareous Lower Plate units. Short intervals of anomalous gold up to 0.534 grams/tone with Carlin-type pathfinder elements were present in six of the seven holes drilled. Two holes with the longest anomalous arsenic intervals were drilled 1,900 feet (580 m) apart, and are located near the Fourmile structure.
The Company's primary target is Carlin-style mineralization in a structural and stratigraphic setting in Paleozoic sedimentary rocks similar to that at the nearby Cortez Hills mine and the adjacent new Goldrush resource. Most of the target is blind, covered by Miocene-age post-mineral gravel and basaltic andesite. The most prominent structure identified to date at Cortez Summit is the Fourmile fault zone, a north-northwest trending structural corridor which trends for 4,500 feet (1,370 m) along the west side of the Property.
The Company is evaluating the recent core drilling program in the context of the 2012 reverse circulation drilling information, and is also reviewing existing ground and airborne geophysical survey data in an effort to enhance future drill targeting.
Cortez Summit is centrally located in Eureka County on the Cortez Trend, in the middle of what has become the most active gold exploration area in Nevada. The Property consists of 142 100%-owned unpatented claims located in the southern Cortez Mountains between the historic Buckhorn and Horse Canyon mines. The east edge of the Property lies 2/3 mile west of the Buckhorn mine, and the west edge of the Property lies 1.5 miles east of the Horse Canyon mine. Barrick's Cortez Hills operation lies 4 miles west of the Property.
Carlin has three projects in northern Nevada including Cortez Summit, all of which represent Carlin-type gold targets. The JDS property consists of 77 100% owned unpatented claims located in Eureka County, in an active exploration area approximately 13 miles southeast of Cortez Summit. The Willow property consists of 89 100% owned unpatented claims located in northeast Nevada.
