Nevada Sunrise (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 (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-enriched massive sulfide lens at Big Mike, which was eventually mined out, would have produced a very strong EM anomaly located below the gravity low feature. A remarkably similar geophysical scenario has been identified at the Coronado anomalies. Nevertheless, an associated gravity high anomaly would be expected with the deeper supergene-enriched lens. However, such an anomaly could be too deep to detect or masked by the gravity low feature or a combination of both these conditions.
This weathering event may be in part recent, but it is more likely related to a protracted, late Permian paleoweathering episode that affected the entire Havallah sequence. Paleoweathering ended upon deposition of stratigraphically overlying Triassic volcanic formations. It would be reasonable to expect that any VMS deposit exposed along the paleoweathering surface which developed over the Havallah sequence to exhibit such geophysical characteristics.
Nevada Sunrise plans to continue testing of the strong EM conductors at Coronado North and South in an upcoming drilling program, in conjunction with downhole EM surveys designed to gather geophysical information at depth.

Coronado currently consists of 133 unpatented claims totaling approximately 2,660 acres (1,104 hectares) located over an interpreted trend adjacent to Big Mike. In 1969, Cerro Corp. published a historical resource estimate for Big Mike of 634,000 tons grading 3.41% copper, which included 74,000 tons of massive sulphide ore grading 11.78% copper, and 380,000 tons of oxide and mixed ore grading 3.16% copper. This historical estimate, which is dated February 21, 1969, uses categories that are not consistent with National Instrument 43-101 (“NI 43-101”) and cannot be readily compared to NI 43-101 categories. A qualified person has not done sufficient work to classify the estimate as a current resource and Nevada Sunrise is not treating the estimate as a current resource estimate. A portion of the ground on which this estimate was based was subsequently mined, and thus this estimate cannot be relied upon. The estimate is relevant to guiding the Company’s exploration plans and provides geological information regarding the type of mineralization that could be present in the Coronado area.
In 1970, Ranchers Exploration and Development Company (“Ranchers”) developed the high-grade portion of the deposit that produced approximately 25 million pounds of copper in 100,000 tons of ore grading 10.5% copper, which was shipped directly to smelters in West Germany and Japan. Heap leaching of lower-grade disseminated copper ore was also carried out by Ranchers; approximately 300,000 tons of mineralized rock was treated. Historical sampling also shows the presence of cobalt at Big Mike, with values in the deposit ranging up to 2,500 parts per million (0.25%) cobalt (Rye et al, Economic Geology, Vol. 79, 1984). Big Mike was mined out in 1970.
