1 Introduction
Summary of Waste Rock and Process Tailings Geochemical Assessment
Piedmont Lithium Project
August 2019
Piedmont Lithium (Piedmont) tasked Marshall Miller & Associates (MM&A) with designing and
implementing a geochemical sampling and analysis program to include both waste rock (overburden)
and process tailings. The purpose of the assessment is to examine the potential for the waste rock and
tailings generated from the proposed Piedmont Lithium Project to have adverse effects on the
environment. With regard to the waste rock, the program included sampling and testing of 101
composited rock core samples from 13 different core holes distributed throughout the four main pit
areas. Sampled hole locations and depth intervals in the holes were designed to provide an evenly
distributed assessment of the proposed mine area. The core samples were collected by both MM&A
and Piedmont Lithium geologists. The program also included 10 process tailings samples collected from
pilot testing activities. Tailings sample collection was conducted by the Minerals Research Laboratory
(MRL) at NC State University in Asheville, North Carolina.
Analyses conducted on the waste rock and tailings samples included Acid Base Accounting (ABA),
"whole rock" elemental determination, and Toxicity Characteristic Leaching Procedure (TCLP). Where
applicable, the ABA analyses results were supplemented with sulfur fractionation (sulfur forms)
analyses to better determine the distribution of sulfidic (pyritic) sulfur in selected samples. In addition,
selected waste rock and tailings samples are currently being analyzed for leachability via humidity cell
testing.
2 Summary
The results of the waste rock analyses indicate no significant potential for the material to produce acidic
conditions. Paste pH values for the samples are typically between 9 and 10, with only shallower
samples of saprolitic rock exhibiting lower paste pH values in the 5-6 range. Total Sulfur for the waste
rock samples is generally in the range of 0.01 to 0.3 percent, with only three of the 101 samples having
a total sulfur content greater than 0.5 percent. Samples exhibiting a sulfur content greater than 0.2
percent were further analyzed using a sulfur fractionation procedure. Results of the sulfur fractionation
analyses indicate that the total pyritic sulfur (acid -producing) present in the samples is very low. With
consideration of the sulfur forms, results show that all waste rock samples exhibit an excess alkalinity
condition. Similarly, ABA analyses for the tailings samples indicate very low Total Sulfur content (0.01
percent), high paste pH values (9.0-9.6), and excess neutralization potential (that is, greater acid -
neutralizing potential than acid -generating potential) for all tailings samples.
Waste rock and tailings samples were also analyzed to determine their overall elemental constituents,
as a means for better understanding the "whole rock" components of the materials. The elemental

analyses results were compared against relevant regulatory guidelines to screen for potentially
problematic components.
The ABA and elemental analyses results were used as a guide for selection of a representative set of
waste rock and tailings samples for further testing via TCLP analysis. The TCLP procedure is a short-
term but aggressive test for detecting contaminants that may leach from the samples. Results of the
TCLP testing were compared against the EPA's "D" list, a list of regulatory levels for the "toxicity"
characteristic as determined specifically from the TCLP test. The TCLP results indicate that all of the
samples yielded results well below D list toxicity threshold levels.
Overall, results of this assessment indicate that acidic drainage is not expected to be released from
either the waste rock (overburden) or the process tailings. In addition, consideration of whole rock
elemental and TCLP test results does not indicate the potential for leaching hazardous levels of
contaminants, as defined by EPA's D list. While the testing done to date does not indicate the potential
for adverse effects from the waste rock or tailings, additional humidity cell leach testing is currently
underway. The humidity cell test results are expected to further confirm the current results.
3 Waste Rock Analysis
Samples representative of waste rock were collected from exploration drill core in November 2018 by
a team of geologists from both MM&A and Piedmont. In total, 101 composite core samples were
collected from core holes stored in the Piedmont core storage building near Lincolnton, North Carolina.
The following table summarizes the number of samples collected from each sampled hole.

3.1 Acid Base Accounting (ABA)/Sulfur Fractionation for Waste Rock Samples
An important consideration in handling and disposing of waste rock is whether, and to what degree,
the rock may generate acid drainage as it weathers upon exposure to oxygen and water. Generally,
acidic, low -pH conditions (acid rock drainage, orARD) promote dissolution and leaching of metals from
rock. The potential for acid generation is principally determined by the sulfidic sulfur content of the
rock; and the degree of acid -neutralizing (alkaline) minerals that may also be present.
The Acid -Base Account (ABA) test was developed to assess the acid -producing and acid -neutralizing
potential of rock materials, and is a well -accepted, standard procedure for that purpose in the mining
industry. As a conservative measure, the possible acid -producing character of each of the 101 samples
was assessed on the basis of its total sulfur content. Only nine of the 101 samples exhibited a total
sulfur content of 0.2 percent or greater (maximum value was 0.73 percent). The 92 samples with less
than 0.2 percent total sulfur content have virtually no potential to generate significant acid.
The nine samples with more than 0.2 percent total sulfur were considered to possibly have some mild
acid -producing potential, depending upon the form of sulfur present and the presence or absence of
acid -neutralizing minerals. Subsequent analyses of sulfur forms in those samples show that very little
of the sulfur is in sulfidic form (maximum is only 0.06 percent), and thus the acid -producing potential is
quite low to non-existent. Further, comparison of neutralizing potential to maximum -possible acid -
generating potential (NP/MPA ratio) reveals that the neutralizing potential (NP) is in every instance
several times the magnitude of the maximum potential acidity (MPA) (see Table 1 below, and laboratory
test results in Appendix A [ABA] and Appendix B (sulfur fractionation]). In summary, results of the ABA
and sulfur fractionation analyses show the planned waste rock material to have virtually no likelihood
of generating acidic drainage, and therefore relatively low potential for leaching of most metals.

3.2 Elemental Analyses of Waste Rock Samples
A further investigative step involved elemental analyses of the 101 core samples by ICP-OES/MS (see
results in Appendix C). Results of these analyses indicate the rock constituency, but do not indicate the
propensity for leaching of constituents to the environment. The results afford a guide for use in
assessing the need for further tests of leachability, and for what parameters.
North Carolina has no regulatory standards specific to elemental concentrations in mine waste rock.
For reference and screening purposes, the elemental analyses results were compared against North
Carolina Department of Environmental Quality (DEQ) Preliminary Soil Remediation Goals for industrial
soils and protection of groundwater'. Results indicate that the rock contains manganese and lithium
at concentrations that exceed the preliminary screening level goal for industrial soil; and that
manganese, lithium, iron, cobalt, and thallium commonly occur at concentrations greater than the
preliminary soil goal for protection of groundwater. While the subject waste rock is not soil and is

unlikely to leach contaminants as readily as industrial soil, the comparisons were used as a guide for
further testing of leachability.
A commonly -used leachability test is the Toxicity Characteristic Leaching Procedure (TCLP), which is
designed to mimic the pH conditions in a municipal landfill (that is, a moderately acidic environment,
which is unlikely to be found in disposal of the subject waste rock). The USEPA has established toxicity
characteristic limits for leachability of eight metals (the RCRA 8 list) using the TCLP test. However, it
should be noted that, because of dilution factors involved in the TCLP, a whole -rock elemental
concentration of less than 20 times the RCRA TCLP limit could not exceed the regulatory TCLP limit,
even if the entirety of that element were to leach out.
Comparison of concentrations in the subject rock samples to 20X TCLP limit for the RCRA 8 metals shows
that none of those metals except chromium could potentially exhibit toxic concentrations, and such
levels of chromium occur only occasionally. The regulatory TCLP limit for chromium is based upon the
hexavalent form of the element, which is potentially carcinogenic and therefore has a very low
regulatory threshold of concern. Chromium in the more common trivalent form is not regarded as
highly toxic, and is not readily mobile in the environment.
3.2.1 Further Investigation of Chromium Presence
To further investigate the chromium concentrations in the waste rock, chromium speciation tests were
conducted to differentiate trivalent chromium from hexavalent chromium in both solid waste rock
material and from the results of the initial flush ("Time 0") of ongoing humidity cell testing. The
speciation testing was conducted on samples 18-BD-205-7 and 18-BD-212-6. As expected, results of
the speciation tests for both solid material and humidity cell effluent indicate that the chromium in the
subject rock is principally or entirely in its reduced, trivalent form (in the mineral Chromite) which is
not readily mobile nor strongly toxic. In sample 18-BD-205-7 (containing 45 µg/g of chromium as
determined by ICP-OES/MS), the concentration of hexavalent chromium in the solid is below detection
(DL = 0.2 µg/g) and the "Time 0" humidity cell effluent is also below the detection limit for both trivalent
chromium (DL= 0.08 µg/L) and hexavalent chromium (DL= 0.2 jig/Q. In sample 18-BD-212-6 (containing
490 µg/g of total chromium as determined by ICP-OES/MS), the concentration of hexavalent chromium
in the solid is below detection, while the first flush of leachable chromium from the humidity cell
contained no detectable hexavalent chromium and only 0.09 µg/L of trivalent chromium. In short, the
chromium present in these samples is essentially all in trivalent form and has very low leachability, even
under the moderately aggressive conditions of the TCLP test (pH of 5, pulverized material). Laboratory
results sheets for the chromium speciation testing for solid material and for the initial "Time 0" effluent
from ongoing humidity cell testing are included in Appendix D.
3.3 Toxicity Characteristic Leaching Procedure (TCLP) for Waste Rock Samples
The TCLP test is frequently used for assessing parameter leachability and for classification of waste
material as hazardous or non -hazardous. As with most laboratory leach tests, the TCLP involves

acceleration of the leaching process in a controlled environment. The TCLP test assumes that the
leaching reaction of the waste rock occurs rapidly. In many ways, the TCLP test can be considered a
"worst case" test, as testing involves pulverized material (increased surface area relative to generally
larger particles that may be expected in the proposed waste disposal), significant agitation of the
material, and use of a lower pH (5) water than is expected to occur in the waste disposal structures.
The TCLP test results for the waste rock are summarized in the table below and laboratory data is
included in Appendix E. Where applicable, the Toxicity Characteristic Limit is shown on the table (third
column from left). The results are that leachate concentrations of elements for which a Toxicity
Characterization Limit is established (including chromium) are all well below (by orders of magnitude)
the respective toxicity threshold values reflected on the EPA D list of potentially hazardous waste
elements. The prominent metal released by the TCLP is iron, at 18.7 to 61.5 mg/L in the TCLP leachate.
The iron mobilization is strongly promoted by the TCLP conditions of pH 5 water and pulverized sample
material. It is very unlikely that leaching conditions within the waste rock disposal structures will be
that aggressive, and the TCLP result represents worst -case conditions that are unlikely to occur in the
field.

3.4 Waste Rock - Summary
The results of the waste rock analyses indicate no significant potential for the material to produce acidic
conditions. Paste pH values for the samples are typically between 9 and 10, with only shallower
samples of saprolitic rock exhibiting lower paste pH values in the 5-6 range. Total Sulfur for the waste
rock samples is generally in the range of 0.01 to 0.3 percent, with only three of the 101 samples having
a total sulfur content greater than 0.5 percent. Samples exhibiting a sulfur content greater than 0.2
percent were further analyzed using a sulfur fractionation procedure. Results of the sulfur fractionation
analyses indicate that the total pyritic (acid -producing) sulfur present in the samples is very low. On

the basis of the sulfur forms and the alkalinity present, all waste rock samples exhibit an excess alkalinity
condition and acidic conditions are not expected to develop.
Comparison of elemental analyses results for the waste rock to a 20X TCLP limit suggests that none of
the RCRA 8 metals except chromium could potentially exhibit toxic concentrations. However, results
of chromium speciation testing (differentiating trivalent and hexavalent chromium) for both the solid
material and humidity cell effluent indicate that the chromium in the subject rock is overwhelmingly or
entirely in its reduced, trivalent form (in the mineral Chromite) which is not readily mobile nor strongly
toxic.
TCLP testing of the waste rock samples indicates that the leachate has no parameters that approach
Toxicity Characteristic Limits as described by the EPA's D List. The TCLP testing is currently being
followed up by longer -term humidity cell leach testing. Results of the humidity cell tests will be
summarized following completion, and are expected to confirm the current conclusions from the ABA
and TCLP tests.
4 Tailings
In addition to the 101 core samples collected and analyzed, 10 tailings samples were collected and
analyzed for ABA, elemental content, and TCLP. The tailings samples originated from processing work
completed at the Minerals Research Laboratory (MRL) at NC State University in Asheville, North
Carolina. Testing of the tailings samples was carried out in the same manner as the waste rock, with
the exception that sulfur forms testing was not performed as none of the samples exhibited significant
total sulfur contents.
4.1 Acid Base Accounting (ABA) for Tailings Samples
The ABA results for the tailings samples are summarized in the table below and associated laboratory
data are included in Appendix A. ABA analyses for the tailings samples indicate a very low Total Sulfur
content (0.01 percent), above -neutral paste pH values (9.0-9.6), and excess neutralization potential for
all samples.

4.2 Elemental Analyses for Tailings Samples
Elemental analyses of the process tailings were conducted to determine the concentrations of
individual elements in the material. A summary of the elemental analyses results is included in the
table below, and laboratory data are included in Appendix C. While the results of the elemental
analyses are not necessarily indicative of the potential for contamination to be released, the analyses
help to characterize the material and guide the selection of samples for any further analyses in
subsequent phases. Comparison of tailings element concentrations to that of the waste rock reveals
that the tailings generally have lower concentrations of metals of concern than does the waste rock.

4.3 Toxicity Characteristic Leach Procedure (TCLP) for Tailings Samples
The TCLP test results for the tailings samples are summarized in the table below and laboratory data
are included in Appendix E. TCLP testing of the tailings samples was conducted in the same manner as
testing of the waste rock samples.

As was the case for the waste rock samples, leachate concentrations of elements for which there is an
established Toxicity Characteristic Limit are all several orders of magnitude below the respective
toxicity threshold value. The potential for significant leaching of any parameters from the tailings,
including iron, is indicated to be quite low.
4.4 Tailings - Summary
The process tailings to be produced from the proposed project are not expected to produce acidic
discharge. Additionally, TCLP results indicate that the material is not expected to produce discharge
MARSHALL MILLER & AssociATES INC. 14

;jHjkLLNNLLE
ES °
Summary of Waste Rock and Process Tailings Geochemical Assessment

with concentrations that exceed the Toxicity Characteristic Limit for materials on the EPA's D List; or
that cause adverse environmental conditions.
5 Conclusions
The results of this assessment indicate that acidic drainage is not expected to be released from either
the waste rock (overburden) or the process tailings. In addition, whole rock elemental and TCLP test
results do not indicate the potential for leaching of contaminants at hazardous levels, as defined by
EPA's D list. Research of public records suggests that no significant environmental issues have been
reported to be associated with the previous lithium pegmatite mining in the region; and results of this
current testing program are consistent with that general indication.
6 Ongoing Work — Humidity Cells
Additional laboratory testing, in the form of humidity cell tests, is ongoing as of the time of issuance of
this report. Samples 18-BD-205-7, 18-BD-212-6, and Tailings 4 were selected for humidity cell testing.
Humidity cell testing provides insight with regard to the potential for acid leachate generation and the
primary rates of reaction under aerobic weathering conditions. The selected samples are also part of
the TCLP test group, so that results from both tests can be compared. The humidity cell testing was
initiated on May 24, 2019, and final results are not yet available. As previously discussed, chromium
speciation analysis was conducted on the "Time 0" effluent for the waste rock samples (18-BD-205-7
and 18-BD-212-6) to determine that the chromium concentrations in the subject rock are of the
trivalent form (and not in the hexavalent form). Humidity cell testing was part of the original sampling
and analysis plan and the results from the testing are expected to further confirm the conclusions from
the other portions of the plan. The duration of humidity cell testing is difficult to predict, as it is
dependent upon each sample's individual mineralogical characteristics. Results of the humidity cell
testing are expected to be reported on a monthly basis, with the testing expected to conclude after
three months.

Subject: Addendum Report: Results of Humidity Cell Leaching Tests, Piedmont Lithium Project
Dear Patrick:
Enclosed is the report "Addendum Report: Results of Humidity Cell Leaching Tests, Piedmont Lithium
Project". As was expected based on the previous testing results (elemental analyses, acid -base
accounting, and Toxicity Characteristic Leaching Procedure), the humidity cell leaching program results
continue to confirm that there is virtually no likelihood of acidic drainage to be generated by the subject
site's waste rock or process tailings materials, over any timeframe; and that leaching of metals is very
unlikely to reach concentrations of potential health or environmental concerns.
We appreciate the opportunity to have assisted you in this important investigation. If you have any
questions regarding any of the enclosed, please do not hesitate to contact us.
Sincerely,

1 Introduction
Addendum Report:
Results of Humidity Cell Leaching Tests, Piedmont Lithium Project
December 2019
In August 2019, Marshall Miller & Associates (MM&A) submitted to Piedmont Lithium a report
summarizing our evaluation of the geochemical environmental impact potential of waste rock and
process tailings that would result from the proposed Piedmont Lithium mine project near Bessemer
City, North Carolina. That evaluation, based on laboratory test results including acid -base account
(ABA), elemental analyses, and Toxicity Characteristic Leaching Procedure (TCLP) analyses of multiple
samples representing waste rock and tailings materials, concluded that neither the waste rock nor the
tailings would generate acidic drainage, and would not be expected to leach contaminants at hazardous
levels. As of that August 2019 timeframe, additional testing of leaching potential was in progress,
through a 20-week duration humidity cell leaching protocol. That humidity cell testing program is now
complete. The results continue to support the indications from previous testing that no acidic or
hazardous drainage is to be expected from on -site disposal of the subject materials. This report
documents the humidity cell leaching test results and provides a brief summary discussion of
characteristics and trends observed.
2 Humidity Cell Testing Program
Two samples of potential waste rock material and one sample of the expected process tailings material
were selected for humidity cell leaching tests, based on the completed ABA, elemental composition,
and TCLP results. A 20-week leaching and testing program was initiated in mid -June 2019 and
completed at the end of October 2019.
One kilogram of each sample was crushed to pass a 0.25-inch screen and then placed in a four -inch
diameter, eight -inch tall humidity cell. The initial leach at the beginning of the period is designated
Week 0. Thereafter, each weekly cycle consisted of three days of dry air exposure passed through the
cell from the bottom, three days of humid air exposure in the same manner, then a flush using one liter
of deionized water added through the top of the cell and allowed to stand for one hour. Each weekly
leachate sample was analyzed as to pH, acidity, alkalinity, electrical conductivity (EC), and sulfate. An
extensive analysis suite of metals was performed weekly through Week 5, then every fifth week for the
remainder of the program period. The initial leach (Week 0) was analyzed for hexavalent chromium (in
addition to total chromium, which was included in the extensive metals analytical suite). The test
program duration was intended to clearly define both the long-term acid generation potential and the
long-term metals leaching potential, and that objective was satisfied by the 20-week program. As is
discussed further below, the trends of relative weathering rates of acid -generating and acid -
neutralizing sources point conclusively to there being no potential for significant acidic drainage from
any of the tested materials, and the weathering release of metals is at a very low rate that diminished
with time.

3 Testing Results
Addendum Report:
Results of Humidity Cell Leaching Tests, Piedmont Lithium Project
December 2019
Two waste rock samples were selected for humidity cell testing, based on their geochemicaI differences
in TCLP testing and ratio of acid neutralization potential to maximum potential acid generation
(NP/MPA ratio). Sample 18-BD-205-7 (205-7) exhibits a NP/MPA ratio of 31.20, which is moderately
high in comparison to most of the waste rock samples. Sample 18-BD-212-6 (212-6) has a NP/MPA
ratio of 2.46, which is moderately low in comparison to most of the samples. The one tailings sample
(Tailings 4) exhibits a NP/MPA ratio of 5.65, but is of very low potential reactivity in any regard (it has
very low sulfide and very low neutralization potential).
3.1 Potential for Acidic Drainage
While the NP of each sample exceeds its MPA in the unweathered state, the acid -generating and acid -
neutralizing minerals may weather at unequal rates leading to depletion of one before the other. In
the subject tests, however, results show that the weathering rate of sulfide (depletion rate) exceeds
that of the neutralization potential, such that the potential for generation of acidic drainage, which is
extremely low in the samples to begin with, diminishes even further as weathering progresses.

Note that in the two waste rock samples the rate of carbonate (CO3) NP depletion is lower than the rate
of sulfide (MPA) depletion, but in the tailings sample only the total NP (not the carbonate NP) retains a
lower rate of depletion than that of the sulfide. There is very little sulfide or carbonate in the tailings
sample, and its NP is substantially from clays or other non -carbonate constituents. In any event, all
three samples show the total NP to exceed the MPA before weathering, and the MPA to be depleted
at a faster rate than the NP such that any potential for acidic drainage to result from any of these
materials is essentially nil. The pH values of weekly leachates remained circum-neutral throughout the
test period (6.98 — 8.01 in the waste rock samples, and 6.34 — 7.27 in the tailings sample).

3.2 Potential for Significant Release of Metals
Addendum Report:
Results of Humidity Cell Leaching Tests, Piedmont Lithium Project
December 2019
During the humidity cell leaching program, no dissolved concentrations of any parameter exceeded
(or even approached) an applicable regulatory groundwater standard (USEPA Drinking Water
Standard or North Carolina Ground Water Standard), with the marginal and temporary exception of pH
in the Tailings 4 leachate in Weeks 14, 15, and 20. The minimum pH value was 6.34, slightly below the
6.5 — 8.5 pH range targeted in those regulatory guidances.
As is noted on Tables Z 3, and 4, the peak concentrations of most parameters generally occurred in the
initial flush, and if not then, within the first three leaching events. The general trend for the great
majority of parameters was a decline in concentration over time, with the lowest concentrations
occurring at or near the end of the test period. The parameter phosphorus is the consistent exception
to that trend, but its concentrations remain extremely low throughout.
Because some regulatory standards for chromium are based upon the toxic and mobile hexavalent
form, the valence state and mobility of chromium present in the samples was specifically evaluated.
The humidity cell leaching test results confirm the earlier indications of low mobility and support the
conclusion that the chromium present in these samples is essentially all in the trivalent form, and is of
low toxicity and low leachability.
4 Summary and Conclusions
As expected, the results of the humidity cell leaching program support and confirm the indications of
earlier testing that neither the waste rock nor the process tailings material at the subject site are likely
to generate significant hazardous leachings to groundwater. The potential for acidic drainage from
these materials is essentially nil, and the dissolved constituents in the weekly leachate collections are
all at levels far below any regulatory concern. As was noted in the August 2019 report on findings based
on elemental, ABA, and TCLP analyses, research of public records suggests that no significant
environmental issues have been reported to be associated with the previous lithium pegmatite mining
in the region; and results of recent testing, including the humidity cell leaching program, are consistent
with that indication.
