Cauchari JV Drill Program Update
Initial results from CAU09 rotary hole average 662 mg/l lithium
Mg/Li ratio of 2.2:1

Vancouver, British Columbia, October 24th , 2017 – Advantage Lithium Corp. (the 
"Company" or "Advantage Lithium") (TSX Venture: AAL) (OTCQX: AVLIF) is pleased 
to announce further positive progress with its Cauchari JV drilling and pumping 
program where three drill rigs are now expanding the depth and lateral extent 
of the existing NI43-101 mineral resource dated December 2016[1].

CAU09 drilling results

The second rotary hole CAU09 is located in the SE sector of the project, 
approximately 2.5km SW from recently completed CAU10. Filter and casing 
sections along with gravel pack were installed to the 400m hole depth. The hole 
was subsequently cleaned and developed prior to the preliminary pumping test 
and sampling completed on the hole. The flow rate from this initial test was 4 
l/s, with filters installed in the hole in intervals between 60m and the 
planned depth of 400 metres. The hole was constructed with 8 inch steel casing 
and filters to a depth of 125 m, to provide a chamber for the pump to be 
installed in, with 6 inch casing and filters to the base of the hole at 400 m 

A preliminary pumping test of 2.5 hours has been completed on CAU09, with 21 
samples taken during the test, averaging 662 mg/l lithium and 6,169 mg/l 
potassium, with an average low Mg/Li ratio of 2.2:1. Quality control/assurance 
included three duplicate, 5 standard and 3 blank samples. All analyses were 
completed in a commercially accredited laboratory in Argentina.[2] These 
initial pumped brine samples compare to an average of 682 mg/l for CAU10 and 
approximately 700 mg/l for Lithium Americas Corp. (LAC) hole PB1^3, ~2.5 km to 
the northeast and ~2.5 km to the north respectively. 

CAU09 intersected a sequence of halite, clay and some sand like hole CAU10. The 
flow rate from the preliminary pumping test in CAU09 is similar to the closest 
LAC production well (PB1), which was flow tested at 4 l/s over 8 days[3]. 
Further to the north in the core of the salar CAU10 displayed a sustained flow 
rate of 2 l/s over the preliminary 48 hour pumping test. 

The lithologies intersected in CAU09, CAU10 and PB1 are predominantly compact 
halite, confirming these holes are located in the halite core of the Cauchari 
salar. The halite core is interpreted to be limited to this central area of the 
salar, with more interbedded units of clay, halite, silt and sand located 
further to the south and east of CAU09, as intersected in drilling by Orocobre 
subsidiary South American Salars (SAS) in 2011. This area southeast of the 
halite core is now the focus of drilling with the remaining rotary holes (CAU08 
and CAU11) in the SE sector. This will provide information on changes in 
sediment type and porosity/permeability away from the halite core. 

NW Target Area 

In salars it is typical that some areas display lower porosity and permeability 
characteristics (such as the halite core) and it is important to define areas 
with different flow and lithium grade characteristics for project planning and 
feasibility purposes. The operating Olaroz brine project ~20 km to the north of 
the Cauchari JV operates production wells extracting brine at a range of flow 
rates and lithium grades, with the most productive wells producing from sandy 
units (see Orocobre announcement - Olaroz Project Large Exploration Target 
Defined Beneath Existing Resource 23 October, 2014). 

The Cauchari JV has been drilling sandy material in hole CAU07 in the NW target 
area, with more details to be provided as they become available.

New rotary drill holes in the SE Sector

In line with the program plan, the rotary drill rigs from hole CAU09 and CAU10 
are currently drilling at sites CAU08 and CAU11 where they have reached the 
target depth of 400 m. These holes are now being widened to allow installation 
of pipe and filters. Drilling intersected a sequence of silt, clay, halite and 
sand. Further information will be provided as it comes available when wells are 
installed and sampled.

President & CEO Mr. David Sidoo said: "The drilling program has now picked up 
speed with three rigs on site. CAU09 has returned a lithium grade averaging 662 
mg/l, which is very positive for the project and confirms our initial 
expectations of lithium brine chemistry that is similar to the nearby Olaroz 
lithium facility. The deeper drilling to 400 m has confirmed extension of brine 
to this depth, with positive implications for resource expansion. With holes 
CAU08 and CAU11 now having reached their target depths we look forward to 
reporting brine results from these holes and diamond hole CAU07 in the NW 
Sector in the near future."
