Nevada Copper Intersects 105 Feet of 2.55% Copper in the East Deposit
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Nov 3, 2015) - Nevada Copper Corp. (TSX:NCU) ("Nevada Copper" or the "Company") is pleased to announce results from its diamond drilling program on the East underground deposit at the Company's 100% owned Pumpkin Hollow project ("the Project") located near Yerington Nevada.
Underground Drill Program
The first phase of underground drilling has been completed from two underground drilling stations located on the 1,900 foot production haulage level. Several of the holes had significant intervals reporting over 2.5% copper. Ten development holes, and one shaft geotechnical hole, were drilled for a total of 2,965 meters (9,728 feet). The program focused on enhancing the mineralized zones within the current mineral reserve, especially in areas planned for mining in the early years. Additional detailed geotechnical data was also collected for refining the mine designs. Summary assay results for 10 holes are reported below.
A second phase of follow-up drilling will be planned for 2016 once data compilation is completed.
Highlights
NC15U-02 encountered several zones of high grade mineralization, the largest intersecting 26.4 meters (86.6 feet @ 2.79% Cu) 24.8 meters true thickness.
NC15U-03 intersected several higher grade zones within a large zone of mineralization, the larger zone intersected 120.1 meters (394.0 feet @ 1.21% Cu) true thickness.
NC15U-06 intersected a very broad zone of mineralization intersecting 176.8 meters (580.0 feet @ 1.01% Cu) 166.1 meters true thickness that extended beyond the existing designed stopes. The mineralization remains open as the hole ended in mineralization.
NC15U-08 and NC15U-09 encountered multiple mineralized zones of varying thickness. NC15U-08 intersected a thick zone 75.1 meters (246.5 feet) grading over 1.0% copper that also included higher-grade intervals. The widest zone in NC15U-09 intersected 40.2 meters (132.0 feet @ 1.60% Cu) true thickness. The hole did not completely go through the stope area and ended in mineralization. Several new zones were also intersected (see figure 1).
NC15U-10 also intersected multiple zones of mineralization including 32.1 meters (105.4 feet @ 2.55% Cu) 31.6 meters true thickness and 46.2 meters (151.5 feet @ 1.48% Cu) 45.5 meters true thickness. Over 290 feet of intercepted mineralization was above the average underground reserve grade (1.29% copper from May 2015 NI 43-101 Technical Report). Mineralization was also expanded outside the present stope designs.
Several of the drill holes did not reach the targeted zones. Holes NC15U-01, NC15U-05 and NC15U-07 deviated out of the target area, and hole NCU-04 was lost.
Greg French, Vice President of Project Development & Exploration, commented, "The initial phase underground drilling by way of two drill stations has proven to be successful in intersecting and expanding previously- defined mineralization. These are the first underground holes drilled at Pumpkin Hollow and we gained considerable knowledge regarding geotechnical and drilling conditions that will be useful in our next phase of drilling.
"Multiple zones of high grade copper mineralization with good gold and silver credits were intersected in the holes. For example hole NC15U-02 intersected 26.4 meters @ 2.79% Cu (86.6 feet @ 2.87% CuEq) and NC15U-10 intersected 18.3 meters @ 2.60% Cu (60.0 feet @ 2.89% CuEq) with several individual assay intervals exceeding 1 gram/ton gold.
"It should also be noted that in drill hole NC15U-06, with a very long zone of mineralization, 176.8 meters (580.0 feet @ 1.01% Cu) also ended in mineralization.
"Hole NC15-09 ended in mineralization as it only partially drilled through the stope area, intersecting 40.2 meters (132.0 feet @ 1.60% Cu). The first part of the hole expanded several high grade zones closer to the shaft (see figure 1).
"Both NC15U-06 and NC15U-10 intersected mineralization that extended well beyond the current designed stopes. The new mineralization is expected to enhance the currently-defined resource."
