Clayton NE program ends with 100% drilling success rate and 5.54 km mineralized brine trend
VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 3, 2017) - Advantage Lithium Corp. (the "Company" or "Advantage Lithium") (TSX VENTURE:AAL)(OTCQX:AVLIF) and its joint venture partner, Nevada Sunrise Gold Corp. ("Nevada Sunrise"), are pleased to announce that the final two holes of the 2016-2017 drilling campaign at their Clayton Northeast property ("Clayton NE, or the "Property") in Clayton Valley, Nevada, have intersected lithium in brine of up to 238ppm (hole CNE-17-05).
All six boreholes from the 2016/17 program intersected lithium-bearing brines in typical Clayton Valley aquifer systems. As a result of interpreted faulting and displacement, the sixth borehole, collared in the southwest end of the Property, passed through a major fault zone and was terminated at a relatively shallow depth.
The successful conclusion of the Phase 2 drilling follows positive results previously released from the three Phase 1 boreholes drilled in 2016 (see NRs dated November 1, 2016, December 5, 2016, and December 21, 2016) and from the first borehole of the Phase 2 program, hole CNE-17-04 (see NR dated March 1), which delivered the best results to date at Clayton NE, with Total Composite 426.72m of 243.44mg/l Lithium in Brines.
Ross McElroy, Technical Advisor for Advantage Lithium, commented: "These results conclude what has been a highly successful program at Clayton NE. Drilling during phase one and two has given us a 5.54 km mineralized brine trend that runs parallel to Albemarle's adjacent Silver Peak project, including drill holes that averaged more than 243mg/l over wide intervals and with associated excellent brine flow. We have drilled some of the deepest holes in the Clayton Valley region and encountered potentially untested aquifers. We are very pleased with the first systematic drilling program conducted at Clayton NE and look forward to advancing the project further."
2017 Drilling Program Highlights
About the 2017 Drilling Program
The Phase 2 drilling program was comprised of a total of 1,389.89m (4,560 feet) in three RC holes and used a similar approach to the Phase 1 program that hit wide intercepts of lithium-bearing brine with strong brine flow rates. All six holes drilled in the 2016-2017 Clayton NE program are adjacent to the 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 its production wells.
The second borehole drilled in the Phase 2 program, CNE-17-05, intersected multiple aquifer formations containing brine-producing strata, but with more subdued levels of lithium in brine, which included 164.59m averaging 72.47 milligrams per litre ("mg/l") lithium between a depth of 256.03m and 420.62m metres, including a higher-grade interval averaging 101.45 mg/l lithium over 91.44m from a depth of 304.8m to 396.24m. The borehole was completed to a depth of 420.62m, terminating in Paleozoic bedrock.
The third and final Phase 2 borehole, CNE-17-06, passed through the Angel Island Fault Zone and encountered bedrock at a relatively shallow depth of 327.66m, earlier than in previous holes. The hole was completed to a depth of 347.47m, terminating in Paleozoic bedrock. In general, this hole produced relatively low saline-water flow. The exception was the zone from 262.13m to 268.22m that contained strong brine with lithium concentration of 214 mg/l.
CNE-17-05 - Technical Details
CNE-17-05 was completed to a depth of 420.62 metres (1,380 feet) into Paleozoic bedrock. The stratigraphy in the area of this hole has been affected by faulting and displacement and did not encounter the Main Ash marker unit. Lower lithium concentrations in brine were encountered in the hole than those encountered in other holes in the program. However, lithium concentrations in the zone from 304.8 to 396.24 metres averaged 101.45 mg/l, over 91.44 metres (300 feet). The highest lithium concentration was 238 mg/l in the zone from 304.8 to 310.89 metres. The entire sampled interval from 256.03 to 420.62 metres (164.59 metres) averaged 72.47 mg/l lithium.
CNE-17-06 - Technical Details
CNE-17-06 was completed to a depth of 347.47 metres (1,140 feet). It is interpreted that the hole was collared on the northeast side of the Angel Island Fault and penetrated the Angel Island Fault Zone at a depth of 170.60 metres (560 feet). Sediment cuttings indicate that the drill was in the Lower Gravel Aquifer beneath the fault to depth of 327.66 metres (1,075 feet) where the drill penetrated Paleozoic bedrock. With the exception of the narrow interval from 262.13 to 268.22 metres, this hole produced only weak brines. This interval did, however, produce relatively strong brine with a concentration of 214 mg/l lithium, high concentrations of other alkali metals, high specific gravity, and brine salinity.

In addition to brine samples, throughout the 2016-2017 program drill cuttings were collected for each 1.5 metre interval and over 360 samples were submitted for analysis. Analytical results received for the drill cuttings for five holes of the 2016-2017 program indicate significant lithium values in sediments that range up to 1,440 parts per million ("ppm") lithium, as shown in Table 2 below. Analytical results for cuttings samples collected from hole CNE-17-06 are pending.

Clayton Valley Project Overview
For further information on Clayton NE, including location maps, see the Company's website www.advantagelithium.com.
Groundwater samples were sent to Western Environmental Testing Laboratory in Reno, Nevada for analysis. General chemistry testing included analysis for specific gravity, total hardness and alkalinity, bicarbonate, carbonate, hydroxide, TDS and electrical conductivity. Anions (chloride, sulfate) were analyzed by ion chromatography. Trace metals (lithium, magnesium, boron, calcium, potassium and sodium) were analyzed by ICP-OES. TDS values obtained in the field are measured with a handheld YSI Model 556 Multiparameter Meter, which meets Good Laboratory Practice (as proscribed by the Organization for Economic Cooperation and Development) for calibration and measurement. All depth measurements reported, including sample and interval widths are down-hole. As holes are oriented vertical and geologic stratigraphy is primarily horizontal to sub-horizontal, downhole measurements are assumed to be close to true thickness.
Composite sediment samples were submitted to ALS Minerals in Reno, NV, and analyzed at ALS Minerals in Vancouver, BC. by way of 48-element, four-acid ICP-MS.
