Nevada Sunrise Surveys Find Drill Targets at Roulette Gold Project

 
Nevada Sunrise (TSXV:NEV) has completed ground geophysical and geochemical surveys at the Roulette gold project located in White Pine county, eastern Nevada, at the southeastern extent of the Carlin trend. The 2016 geochemical and geophysical results were integrated into a 3D model, which has provided high-priority targets that Nevada Sunrise plans to drill in the spring of 2017.
2016 Exploration Program
The 2016 exploration consisted of multi-element geochemical sampling along 11.2 line kilometres (6.7 line miles) of grid. In addition, 4 kilometers (2.4 line miles) of Volterra 3D-IP ground geophysical surveying was completed as a follow up to a 2015 survey carried out by Nevada Sunrise. Exploration at Roulette is focussed on determining the extent of two jasperoid outcrops (“Parlay” and “Gambit”) known from historical prospecting and mapping, one of which is mineralized. The Parlay jasperoid was sampled in August 2014 by Nevada Sunrise and returned 4.44 grams/tonne gold over a sample length of 3.30 metres (10 feet), and 1.05 grams/tonne gold over a sample length of 2.64 metres (8 feet).
“Roulette is a classic example of a Carlin Trend project overlooked in recent years because of its sediment cover,” said Warren Stanyer, President and CEO of Nevada Sunrise. “Historical explorers were attracted to Roulette because of the mineralized jasperoid on the property but were unable to determine its buried source. The use of modern geophysical techniques to help outline the extent and depth of favourable geology provides us with targets that can be drilled with a much higher degree of confidence.”
Geochemical Results
A total of 400 soil samples were taken at 25 metre intervals on lines spaced 200 metres apart to complement historical work by U.S. Gold (now McEwen Mining Inc.), and Cordex Exploration Co., prior to the Company’s acquisition of the Project. The 2016 survey lines were extended to the north and east over interpreted faults. Anomalous values ranging up to 15.5 ppb gold, 205 ppm arsenic and 5.1 ppm antimony were found in the soils. The geochemical signature appears to be spatially associated with both jasperoid locations and along interpreted brittle structural faults. This may suggest an association of brittle structure and silicification, a characteristic also consistent with Carlin-type mineralization.
Geophysical Results
The 2016 ground induced polarization/resistivity survey was designed as an extension of the work Nevada Sunrise performed in 2015 over a 1,500 metre-long area, where strong chargeability anomalies were detected in the southern part of the grid, and another chargeability anomaly was partially-surveyed within the northern end of the grid, short of the property boundary. In order to provide a suitable overlap with the latest survey results, data was gathered on the three northernmost lines of the Roulette grid, and then merged and blended with the 2015 results to produce a single, coherent model.
The 2015 survey had delineated three high chargeability anomalies along a NNE trending band of elevated chargeability values that closely follows the interpreted Joana-Pilot Shale contact. The two southern anomalies, A1 and A2, appear to be related to the Parlay and Gambit jasperoid showings. A third anomaly, A3, was mapped on the northernmost survey line along strike from the jasperoid showings. The 2016 survey shows that A3 continues to the north, becoming larger and higher amplitude. It is traced for some 300 plus metres strike length, where it terminates sharply forming an ENE striking lineation along its northern edge. This anomaly appears to form a pod shaped body, narrow and elongated to the northeast. Modelling suggests it has a depth extent on the order of 200 metres and appears to lie on top of the westerly dipping Guilmette formation limestone. Nevada Sunrise considers each of A1, A2 and A3 as prime drill targets.
Combined geological mapping, geochemistry and geophysics (3D-IP survey) have provided three distinct targets for drilling and four proposed drill holes. Nevada Sunrise is in the process of permitting these four drill sites in preparation for drilling in early 2017.
