3.41m @ 1.20% Li(2)O in Hole 17-BD-90
-- 12.51m of cumulative thickness of mineralization across 2 pegmatites
which includes a high grade intercept of 10.55m @ 1.46% Li(2)O in
Hole 17-BD-102
-- The Company has now received assays for 76 of the 93 Phase 2 drill holes
and anticipates receiving assay results for the remaining 17 drill holes
over the next few weeks
-- A Schematic Long Section for the B and G corridors has been prepared
based on drilling results to-date (Figure 1) and illustrates the
continuity of mineralization along strike for 1400 meters
-- Preliminary geological modelling has, thus far, identified 38 pegmatite
bodies within the 4+ kilometers of strike on the Project with the vast
majority being intersected at depths less than 100 meters from surface
-- As a result of the work done to date the Company is confident in
defining a shallow, open-pitable deposit within the Piedmont Lithium
Project strategically located within the USA
Keith D. Phillips, President and Chief Executive Officer, said, "These additional drill results are outstanding and confirm our belief in the Piedmont Lithium Project. Our team has discovered a world-class mineral system with over 30 pegmatite bodies over a combined 4+ kilometers of strike length, virtually all within 100 meters of surface. We look forward to receiving the remaining Phase 2 assay results over the coming weeks."

Piedmont Lithium Limited (ASX: PLL, OTC: PLLLY) ("Piedmont" or "Company") is pleased to report further high-grade mineralisation from the 93-hole Phase 2 drilling campaign on the Piedmont Lithium Project ("Project") located within the world-class Carolina Tin-Spodumene Belt ("TSB").
Phase 2 Results and Discussion
In addition to the first 51 Phase 2 drill holes (reported September 26, 2017 and November 2, 2017), the current group of 26 drill holes reported in this release continue to define high grade mineralised trends totalling over 4 kilometers in strike. The entire Pegmatite system remains open at depth and along strike. Drill hole details and weighted-composite assay intercepts are attached as Table 1.
Geological modelling has begun on the results from the Phase 2 drill campaign with initial results indicating the presence of 38 pegmatite bodies across the 4+ kilometres of strike length on the Project. Importantly, the vast majority of the dykes have been intersected at shallow depths of less than 100 metres vertically. These initial results give the Company confidence in being able to define a shallow, open-pitable deposit which is strategically located within the historical lithium mining and processing region of the USA.
Logging, sampling and shipping of all Phase 2 drill core samples has been completed. All assays from the Phase 2 program should be received from SGS Labs by early-December.
The Phase 2 drill holes reported in this release highlight the initial high grade intercepts with significant cumulative thickness within the Star Corridor (figure 3) and further defined the mineralization in the B, F & G corridors. Significant intercepts within the B, F & G corridors continued to display similar high grade results as have been previously reported.
Significant intercepts from the Star Corridor include:
-- 22.82m of cumulative thickness of mineralization across 4 pegmatites
which includes high grade intercepts of 9.74m @ 1.31% Li(2)O and 5.73m @
1.36% Li(2)O in Hole 17-BD-98
-- 21.86m of cumulative thickness of mineralization across 4 pegmatites
which includes high grade intercepts of 13.95m @ 1.34% Li(2)O and 2.93m
@ 1.41% Li(2)O in Hole 17-BD-95
-- 21.30m of cumulative thickness of mineralization across 4 pegmatites
which includes high grade intercepts of 4.23m @ 1.20% Li(2)O and 4.52m @
1.31% Li(2)O in Hole 17-BD-91
-- 17.42m of cumulative thickness of mineralization across 3 pegmatites
which includes high grade intercepts of 5.35m @ 1.23% Li(2)O and 4.00m @
1.12% Li(2)O in Hole 17-BD-101
About Piedmont Lithium
Piedmont Lithium Limited (ASX: PLL; OTC-Nasdaq: PLLLY) holds a 100% interest in the Piedmont Lithium Project ("Project") located within the world-class Carolina Tin-Spodumene Belt ("TSB") and along trend to the Hallman Beam and Kings Mountain mines, historically providing most of the western world's lithium between 1950 and 1990. The TSB is one of the premier localities in the world to be exploring for lithium pegmatites given its history of lithium bearing spodumene mining, favorable geology and ideal location with easy access to infrastructure, power, R&D centers for lithium and battery storage, major high-tech population centers and downstream lithium processing facilities.
The TSB has previously been described as one of the largest lithium provinces in the world and is located approximately 40 kilometers west of Charlotte, North Carolina, United States. The TSB was the most important lithium producing region in the western world prior to the establishment of the brine operations in Chile in the late 1990s. The TSB extends over approximately 60 kilometers in length and reaches a maximum width of approximately 1.6 kilometers.
The Project was originally explored by Lithium Corporation of America which eventually was acquired by FMC Corporation ("FMC"). FMC and Albemarle Corporation ("Albemarle") both historically mined the lithium bearing spodumene pegmatites from the TSB with the historic Kings Mountain lithium mine being described as one of the richest spodumene deposits in the world by Albemarle. These two mines and their respective metallurgy also formed the basis for the design of the two lithium processing facilities in the region which were the first modern spodumene processing facilities in the western world.
Albemarle and FMC continue to operate these important lithium processing facilities with FMC's Bessemer City lithium processing facility being approximately 14 kilometers from the Project whilst Albemarle's Kings Mountain lithium processing facility is approximately 17 kilometers from the Project.
The Company is in a unique position to leverage its position as a first mover in restarting exploration in this historic lithium producing region with the aim of developing a strategic, U.S. domestic source of lithium to supply the increasing electric vehicle and battery storage markets.

The over-range method code for Li
>5,000 ppm is GE ICP90A, which uses a
peroxide fusion with an ICP finish,
and has lower and upper detection
limits of 0.001 and 5% respectively.
Starting in August, samples were
switched to being analysed using GE
ICP90A Li only and then to GE ICP91A
Li only.
Bulk Densities are collected from each
drill hole (one host rock and one
mineralized rock) using analyses code
GPHY04V.
Phase I samples were shipped to the
Bureau Veritas minerals laboratory in
Reno, Nevada.
The preparation code was PRP70-250
(crush to 70% of sample <2mm,
pulverize 250g to 85% <75 microns).
The analysis code was MA270 (multi-
acid digestion with either an ICP-ES
or ICP-MS finish), which has a range
for Li of 0.5 to 10,000 ppm (1%) Li.
This digestion provides only partial
analyses for many elements in
refractory minerals, including Ta and
Nb. It does not include analyses for
Cs.
The over-range method code for
Li>10,000 ppm is PF370, which uses a
peroxide fusion with an ICP-ES
finish, and has lower and upper
detection limits of 0.001 and 50%,
respectively. The laboratory was
instructed to implement the over-
range method in all samples that
exceed 5,000 ppm Li to allow for poor
data precision near the upper limit
of detection using MA270.
Historical samples (holes 09-BD-01
through 10-BD-19) were submitted to
ALS Vancouver for analysis.
Accuracy monitoring was achieved
through submission and monitoring of
certified reference materials (CRMs).
Sample numbering and the inclusion of
CRMs was the responsibility of the
project geologist submitting the
samples. A CRM or coarse blank was
included at the rate of one for every
20 drill core samples (i.e. 5%).
The CRMs used for this program were
supplied by Geostats Pty Ltd of
Perth, Western Australia. Details of
the CRMs are provided below. A
sequence of these CRMs covering a
range in Li values and, including
blanks, were submitted to the
laboratory along with all dispatched
samples so as to ensure each run of
100 samples contains the full range
of control materials. The CRMs were
submitted as "blind" control samples
not identifiable by the laboratory.
Sampling precision was monitored by
selecting a sample interval likely to
be mineralized and splitting the
sample into two 1/4 core duplicate
samples over the same sample
interval. These samples were
consecutively numbered after the
primary sample and recorded in the
sample database as "field duplicates"
and the primary sample number
recorded. Field duplicates were
collected at the rate of 1 in 20
samples when sampling mineralized
drill core intervals. Random sampling
precision was monitored by splitting
samples at the sample crushing stage
(coarse crush duplicate) and at the
final sub-sampling stage for
analysis (pulp duplicates). The
coarse, jaw-crushed, reject material
was split into two preparation
duplicates, sometimes referred to as
second cuts, crusher or preparation
duplicates, which were then
pulverized and analysed separately.
These duplicate samples were selected
randomly by the laboratory.
Analytical precision was also
monitored using pulp duplicates,
sometimes referred to as replicates
or repeats. Data from all three types
of duplicate analyses was used to
constrain sampling variance at
different stages of the sampling and
preparation process.
Examination of the QA/QC sample data
indicates satisfactory performance of
field sampling protocols and assay
laboratories providing acceptable
levels of precision and accuracy.
