Frontier Lithium Intersects 231m of 1.61% Li2O During Phase II Drilling of the Spark Pegmatite
Frontier Lithium Intersects 231m of 1.61% Li2O
During Phase II Drilling of the Spark Pegmatite
Highlights
Phase II diamond drill program includes four holes drilled totaling
1,159.5m
; all intersecting
significant zones of spodumene pegmatite; assay results have been received for the first 2 drill
hole;
DDH PL-042-19 intersected a total of
231 m
of pegmatite averaging 1.61% Li
2
O, including
25.0m
of 2.75% Li
2
O;
DDH PL-043-19, to the west intersected three narrow (10 to
25m
) dykes which is consistent
with the surface expression of the pegmatite. Grades ranged from 1.0 to 1.5 % Li
2
O;
The deposit displays consistency in both composition and lithium grades across the width of the
pegmatite down to at least
200m
depth;
All indications suggest the Spark Pegmatite is vertically emplaced; open to the west with a
multiple dyke-system extending to the east.

Sept. 24, 2019
/CNW/ -
Frontier Lithium Inc. (TSX.V: FL) (the "Company)
is
pleased to announce the initial results of their second Phase of drilling on the Spark Pegmatite.
Frontier completed four diamond drill holes totaling
1,159.5 m
in July-August 2019. During the drill
program an additional 4 channels totaling
52 m
were cut and most of the exposed outcrop surface in
the immediate area of the pegmatite was mapped. Geochemical results from the first two drill holes
have been received. The remaining analysis is expected by the end of October.
Figure 1 is a location map showing the surface outline of the Spark pegmatite, location of channels
and drill hole traces with geology overlain on detailed imagery of the outcrop area. Phase I drilling in
February focused on targeting the pegmatite from the south along the base of the 30 to
40 m
high
ridge of predominately pegmatite. Three holes were drilled during Phase II from the top of the ridge
back towards the Phase I collars and the fourth hole was a re-drill of hole PL-037-19 which had
been abandoned.
All holes intersected significant widths from 20 to
125 m
of pegmatite. Spodumene grain size and
abundance tends to increase with the presence of quartz and feldspar megacrysts which is similar to
the LIZ (Lower Intermediate Zone) and locally similar to the CIZ (Central Intermediate Zone) of the
PAK Pegmatite. The exposed pegmatite and host metavolcanic rock has been mapped over most of
the immediate area (Figures 1). Overburden stripping is required to the west and to the east in the
area of Channels 39 and 40.

See Press Release dated
April 9,2019
) Surface observations and the drill intersections
indicate there are two, possibly three main pegmatite zones/dykes that are 50 to
75m
wide on the
western margins with much narrower dykes to the east.

"We are extremely pleased with the drilling results and are confident that enough information is
available to complete a resource estimate before year-end." commented
Garth Drever
, Vice
President of Exploration. "We are currently compiling a 3-D model using the digital elevation model,
surface mapping, channels and drill data. Due to the effectiveness of the drilling we believe there is
adequate data to support a resource estimate with both Indicated and Measured categories
included. The reality for an at-surface deposit to augment the PAK project resource size is genuine."
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, all drilling was completed by Chenier Drilling Ltd. of
Val Caron, ON
using thin-walled BTW drill rods (4.2 cm core diameter) and a Reflex ACT III oriented
core system. Using the Reflex system, the drill core was oriented and marked as it was retrieved at
the drill. The core was boxed and delivered to the Frontier core shack where it was examined,
geologically logged and marked for sampling. The core was photographed prior to sampling. Using
a rock saw, the marked sample intervals were halved with one halve bagged for analysis. Sample
blanks along with 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. The samples were placed in
poly sample bags and transported to
Red Lake
by Frontier employees and then shipped to AGAT
Laboratories Ltd. (AGAT) in
Mississauga, ON
for quantitative multi-element analysis. AGAT is an
ISO accredited laboratory. The core is stored on site at the Pakeagama Lake exploration camp.
About Frontier Lithium
Frontier Lithium is a Canadian junior mining company with the largest land position in the Electric
Avenue, an emerging premium lithium mineral district located in the Canadian Shield of northwestern
Ontario
. The company's PAK Lithium Deposit contains
North America's
highest concentration of rare
low-iron spodumene. Frontier Lithium's objective is to firstly become a near term producer of
premium technical grade lithium mineral concentrates of 2,000 tonnes of Lithium Carbonate
Equivalent ("LCE") for glass producers. Through a phased approach to scale up to 20,000 tonnes by
2025 by ramping up production of concentrates and building a downstream processing facility to
produce lithium chemicals required by glass and battery materials producers.
Frontier maintains a tight share structure with management ownership exceeding 30% of the
Company.

2
O which has a rare technical/ceramic grade spodumene with low inherent iron
(below 0.1% Fe
