Nevada Sunrise (TSXV:NEV) and its exploration partner, Advantage Lithium Corp. (“Advantage Lithium”) (TSXV: AAL) are pleased to announce that the first borehole of the 2017 drilling campaign at their Clayton Northeast property (“Clayton NE, or the “Property”) in Clayton Valley, Nevada, has intersected lithium-bearing brines. This follows successful results from the first three boreholes drilled in 2016 (see Nevada Sunrise news releases dated November 1, 2016, December 5, 2016, and December 21, 2016). Hole CNE-17-04, drilled to a total depth of 609.6 metres (2,000 feet), has intersected multiple aquifer formations, including 426.72 metres of brine-producing strata averaging 243.44 milligrams per litre (“mg/l”) lithium between a depth of 140.21 to 609.6 metres, including a higher-grade interval averaging 274.6 mg/l lithium over 79.2 metres from a depth of 530.35 metres to 609.6 metres.

“Exploration drilling at Clayton NE continues to intersect classic Clayton Valley aquifer systems containing lithium,” said Warren Stanyer, President and CEO of Nevada Sunrise. “Every successful hole brings us closer to our goal, and that of our partner, Advantage Lithium, of producing a lithium brine resource estimate for Clayton NE.”

The Phase 2 drilling program is comprised of a total of approximately 1,800 metres (5,905 feet) in three reverse circulation (“RC”) holes expected to test depths of a minimum 600 metres each. Using a similar approach to the successful Phase 1 program that hit wide intercepts of lithium brine with strong brine flow rates, these new holes are focused on high-priority conductive horizons identified and imaged in the 2016 3-D resistivity survey and confirmed by drilling to be lithium-bearing brines. All four holes drilled to date are adjacent to Silver Peak lithium brine field operation, North America’s only producing lithium mine, operated by Albemarle Corporation (“Albemarle”) (NYSE: ALB) in close proximity to several of their production wells.

2017 Drilling Program Highlights

  • Continued 100% Drilling Success Rate with Strong Lithium Brine Results. Hole CNE-17-04 has intersected multiple aquifer formations:
    • Total composite of 426.72m of brine producing strata at an average grade of 243.44 mg/l lithium, including:
    • 274.6 mg/l lithium over 79.2 metres (530.35m to 609.6m)
  • Extension of mineralized brine trend to 4.46km. The highly-successful Phase 1 program defined a 3.43km mineralized trend. The results of Phase 2 drilling to date has extended this trend length to 4.46km.
  • Drilling deeper into potentially untested aquifers. Phase 2 holes are targeting possible deeper aquifers that may not have been intersected by previous drilling in the Clayton Valley. Previous hole CNE-16-03, from the Phase 1 program, was one of the deepest boreholes drilled in the Clayton Valley and, based on results obtained, may have hit a previously untested aquifer.
  • Permits/waivers obtained for future development of a lithium brine resource and wells. In November 2016, waivers were received from the Nevada Division of Water Resources for 5 of the 6 permitted holes, which allows for reaming a borehole to a larger diameter well, pump testing, and flow rate determination in order to provide the necessary technical information for development of an initial lithium brine resource at Clayton NE.

CNE-17-04 – Technical Details

CNE-17-04 was completed to a depth of 609.6 metres (2,000 feet), intersecting the base of the Clayton Valley salar sedimentary basin at 579.12 metres (1,885 feet). Drilling has intersected typical Clayton Valley strata consisting of alternating layers of gravel, volcanic ash and clay as well as units consisting of carbonate deposits and other evaporites. A total of 80 grab groundwater samples were collected as brine-bearing formations were encountered. Table 1 presents a compiled summary of the depths of the aquifer systems with brine interval thickness and associated average lithium grades and TDS concentrations. Anomalous lithium results with average concentration of 243.44 mg/l were obtained from six (6) discrete brine-bearing formations intersected over a 469.39 metre section (from 140.21 to 609.6 metres) within the Salt Aquifer, Main Ash Aquifer, Tufa Aquifer, Lower Aquifer System, Lower Gravel Aquifer, and a possible fractured bedrock aquifer.

Within this section, a 24.38 metre interval composed of compacted, confining clay was intersected from depth of 158.50 to 182.88 metres. Water was not produced from this unit. This zone is not included in the calculation of total average lithium concentrations. In addition, recoverable water was not present in three 6.1-metre intervals within this 469.39-metre section because of excessive fine-grained solids content. The Salt Aquifer System contains two brine-bearing zones (A and B as shown in table 1) separated by an unsampled zone from 146.30 to 152.40 metres. The Main Ash Aquifer contains two brine-bearing zones (A and B as shown in Table 1) separated by an unsampled zone from 188.98 to 195.07 metres. The Lower Aquifer System contains one unsampled zone from 249.94 to 256.03 separating the aquifer into two brine-bearing zones as shown in Table 1 (Lower Aquifer System – A and B). These three unsampled zones are not included in the calculation of total average lithium concentrations for these aquifers.

The highest grade results were obtained in the Main Ash Aquifer with a peak concentration up to 310 mg/l lithium (182.88 to 201.17 metres), and in the deeper Lower Gravel Aquifer, with a peak concentration up to 301 mg/l (219.46 to 225.55 metres). In addition to brine samples, drill cuttings were collected for each 1.5 metre interval and 87 samples have been submitted for analysis. Analytical results for the drill cuttings are pending.
