have been received for 1 drill hole with results pending for the remaining 4;
DDH PL‐038‐19 intersected 215m of pegmatite averaging 1.4% Li 2O,
including 62.0m of 1.81% Li2O;
Lithium grades are consistent across the entire width of the pegmatite;
The Spark Pegmatite appears to be vertically emplaced.
Sudbury, Ontario, April 9th, 2019 – Frontier Lithium Inc. (TSX.V: FL) (the “Company)
is pleased to announce the results of the first of five diamond drill holes completed on the
Spark pegmatite. DDH PL‐038‐19 was drilled underneath the surface sequence of Channels 33
to 36 (see Figure 1 and 2). The hole was collared in pegmatite and was drilled through 3
significant pegmatite zones totaling 215m of pegmatite averaging 1.4% Li2O.
During February 2019, a total of 1,340 metres was drilled in 5 holes on Frontier’s newly
discovered Spark pegmatite (Table 2). Four holes were drilled from the south at the base of the
topographic high hosting the pegmatite. The fifth hole (PL‐041‐19) was drilled from the north
on top of the ridge and was also collared in pegmatite. Figure 1 is a plan map showing the
rough surface outline of the Spark pegmatite, location of channels and drill hole traces with
geology overlain on detailed imagery of the outcrop area.
Table 1 shows a summary of DDH PL‐038‐19 including significant mineralized intercepts. There
are 3 pegmatite zones, including two zones, 80 and 100 metres averaging 1.58 and 1.25% Li2O
respectively. The pegmatite is characteristically similar to the LIZ (Lower Intermediate Zone)
locally to the CIZ (Central Intermediate Zone) at the PAK Pegmatite. The high grade UIZ (Upper
Intermediate Zone) is conspicuously absent, however, 1 to 3m wide high‐grade zones (>4%
Li2O) commonly occur throughout the pegmatite zones. Of note is a 5.3m wide zone of CIZ
averaging over 2,000 ppm Ta2O5. Figure 2 is a section displaying the drill hole and channels
above. Significant intersections of Li2O and Ta2O5 graphically displayed for both the drill hole
and channels. A preliminary interpretation of the pegmatite and host rock (metavolcanics
schist) is displayed on the section.

* Assuming the Spark pegmatite is vertically oriented the Horizontal distance equals the "true width" when the Azimuth of the drill
hole is perpendicular to the strike of the deposit (070 to 090 degrees).
** Units within the Spark pegmatite resemble the Central and Lower Intermediate Zones (CIZ and LIZ) at the PAK Pegmatite
“We are extremely pleased with these initial results and are eagerly looking forward to the results
from the remaining 4 holes.” commented Garth Drever, Vice President of Exploration. “The
drilling and consistency of grades confirm our initial prediction that the Spark pegmatite is
vertically emplaced and extensive. The potential for an at‐surface resource to augment the PAK
deposit on the project is high.”

Due Diligence
All scientific and technical information in this release has been reviewed and approved by Garth
Drever, P.Geo., the qualified person (QP) under the definitions established by National
Instrument 43‐101. Under Frontier’s QA/QC procedures, channels are cut with a motorized
circular diamond saw, and are 4 cm wide and 10 cm deep. The channels are typically oriented
perpendicular to the strike of the pegmatite internal mineralogical zones and are cut
continuously across the zones. The samples are removed using a hammer and chisel. The length
of a channel is determined by the width of the pegmatite zone. Offset channels are cut where
deemed appropriate. Sample lengths typically are 1 metre but can be less depending on zone
mineralogy and boundaries. Samples are described, placed into a poly sample bag with a
numbered sample tag and then shipped to the assay lab for quantitative multi‐element
analysis.
All samples were assayed by AGAT Laboratories Ltd. (“AGAT”), an ISO accredited laboratory in
Mississauga, Ontario. Sample blanks along with tantalum, lithium, rubidium and cesium
certified reference material was routinely inserted into the sample stream in accordance with
industry recommended practices. Field duplicate samples were also taken in accordance with
industry recommended practices.
