[{"type":"text","content":" VANCOUVER, May 2, 2019 /CNW/ - Nevada Sunrise Gold Corporation (\"Nevada Sunrise\" or the \"Company\") (TSXV: NEV) is pleased to announce the results of a ground gravity survey at the Coronado VMS property (\"Coronado\", or the \"Project\"), located near the past-producing Big Mike open pit copper mine in the Tobin and Sonoma Range of Pershing County, Nevada, approximately 48 kilometers (30 miles) southeast of Winnemucca. Nevada Sunrise has an option to earn a 100% interest in Coronado (see Nevada Sunrise news release dated September 28, 2018). Results of 2019 Coronado Gravity Survey A ground gravity survey was carried out in April 2019 over the most conductive part of the Coronado South target, with survey lines centered over a strong airborne electromagnetic (\"EM\") anomaly first detected by the Company in 2018. Eighty-four gravity readings were taken at 100 metre station intervals on four lines extending 1,000 metres on either side of the interpreted conductor axis to delineate the gravity profile. An additional 84 gravity readings were also taken over the Coronado North target located approximately 1,750 metres to the north. The 2019 gravity survey outlined zones of low gravity coincident with the Coronado North and South EM anomalies, which was an unexpected result for such highly-conductive zones with higher magnetic susceptibility. Based on specific gravity (i.e., density) measurements from samples taken within the property area, Nevada Sunrise believes that the measured gravity lows could represent the weathered caps (gossans and/or leached cappings) of flat-lying or gently dipping, VMS-style mineralization. This interpretation is supported by field observations at the nearby Big Mike mine (\"Big Mike\"). Here, deep weathering and oxidation (at least 200+ feet) resulted in severe leaching of a near-surface, moderately dipping VMS lens and underlying stringer zone. As a consequence, a well-developed, siliceous and auriferous boxwork gossan zone and leached capping developed. Continued weathering activity culminated in supergene-copper-enrichment of a deeper lens. Nevada Sunrise believes the density contrast between the upper gossan-leached capping and mafic (basaltic) volcanic host Havallah sequence could generate a gravity low similar to those detected by the survey. Further, the deeper copper-enr...
