Advantage Lithium JV Hits Best Hole to Date at Clayton NE: Total Composite 387.69 metres of 243.66 mg/l Lithium in Brines

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec. 21, 2016) - Advantage Lithium Corp. (the "Company" or "Advantage Lithium") (TSX VENTURE:AAL) and its joint venture partner, Nevada Sunrise Gold Corp. ("Nevada Sunrise"), are pleased to announce the best lithium brine drilling results to date at the Clayton NE project in the Clayton Valley, Nevada. This follows successful results from the first two boreholes (see NRs dated Nov 1^st and Dec 5^th, 2016). Clayton NE borders the Silver Peak mine, operated by Albemarle Corporation ("Albemarle"), North America's only producing lithium mine. Hole CNE-16-03, drilled to a total depth of 591.3 metres (1,940 feet), has intersected multiple aquifer formations, including 387.69 metres of brine-producing strata averaging 243.66 milligrams per litre ("mg/l") lithium from a depth of 209.23 to 596.92 metres, including a higher-grade interval averaging 299.5 mg/l over 36.92 metres and a peak measurement of 322 mg/l.

Highlights

• Strongest Results to date. Lithium brines intercepted by 3^rd drill hole at Clayton NE, CNE-16-03, showing a peak values of 322 mg/l lithium, within 387.69 metres averaging 243.66 mg/l. These results are the strongest to date at Clayton NE and are comparable to Albemarle's brine samples from their Silver Peak mining operation immediately adjacent to Clayton NE.
• Potentially Untapped Aquifer. Hole CEN-16-03 is one of the deepest boreholes drilled in the Clayton Valley and, based on results obtained, may have hit a previously untapped aquifer.
• Very Strong brine flows. Brine flows of up to 100 gallons per minute issued from borehole CNE-16-03 between 350.76 to 436.92 metres. Geochemical analysis shows this zone carries significant lithium concentrations. High brine flows are important for economic production.
• 100% Drilling Success Rate and 3.43km mineralized brine trend: All three holes, which are located 3.43km apart, contain significant intervals of mineralized lithium brines
• More Drilling Planned. Three more holes are already permitted and the Company plans to complete these holes in 2017 to continue building towards a resource in Nevada.

Ross McElroy, Technical Advisor and Director, of Advantage Lithium, commented: "This is our strongest hole to date at Clayton NE, with robust grades, strong brine flow and wide intercepts. Even more exciting is the fact that we have drilled one of the deepest boreholes in the Clayton Valley and we may have intercepted an untapped aquifer system. Having hit with all three holes at Clayton NE over the 3.43km mineralized brine trend, we are extremely pleased with the potential of this project, as well as the expertise of our exploration team."

Drill Hole Technical Details

CNE16-03 was completed to a depth of 591.3 metres (1,940 feet), intersecting the base of the Clayton Valley salar sedimentary basin at 584.62 metres. Drilling has intersected typical Clayton Valley strata consisting of alternating layers of gravel, volcanic ash and clay. A total of 62 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 243.66 mg/l were obtained from brine-bearing formations intersected over a 387.69 metre section (from 209.23 to 596.92 metres) within the Main Ash, Lower Aquifer System, and Lower Gravel Aquifer. The highest grade results were obtained in the Lower Aquifer System with peaks up to 322 mg/l lithium (332.31 to 338.46 metres), and in the deeper Lower Gravel Aquifer, with peaks up to 316 mg/l (504.62 to 510.77 metres). In addition, drill cuttings were collected for each 1.5 metre interval and have been submitted for analysis. Analytical results for the drill cuttings are pending.

Geochemical results for lithium are reported in mg/l rather than parts per million ("ppm") as mg/l is deemed conventional for reporting values of dissolved metals and salts in fluids. Variances in specific gravity of fluids will influence geochemical results if converted from mg/l to ppm. Previously reported values for holes CNE-16-01 and CNE-16-02 are now reported in mg/l as received from the laboratory.

Regarding Sample Analysis

Groundwater grab 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.
