Exhibit 99.4
 

 
ASX RELEASE | June 7, 2018 | ASX:PLL; NASDAQ:PLLL
 
PHASE 3 DRILLING COMPLETED WITH FURTHER HIGH GRADE MINERALISATION IDENTIFIED
 
Piedmont has completed its Phase 3 drill program on the Core property and has received assay results from an additional 26 holes, with high grade mineralisation in all holes including:
 
o
23.3m of cumulative thickness of mineralization (non-continuous) across 5 pegmatites which includes high grade intercepts of 5.2m @ 1.30% Li2O, 7.5m @ 1.37% Li2O and 5.2m @ 1.58% Li2O in Hole 18-BD-189
 
o
28.5m of cumulative thickness of mineralization (non-continuous) across 4 pegmatites which includes high grade intercepts of 8.4m @ 1.47% Li2O, 5.2m @ 1.53 Li2O and 11.4m @ 1.00% Li2O in Hole 18-BD-220
 
o
20.4m @ 1.61% Li2O of continuous mineralization across 1 pegmatite, including a high-grade zone of 11.0m @ 2.04% Li2O in Hole 18-BD-228
 
Maiden Mineral Resource estimate for the Core property to be announced in the coming weeks
 
Hole 18-BD-228 is the thickest single pegmatite to date on the property with over 20 meters of continuous high-grade mineralization (20.4m @ 1.61% Li2O)
 
Exploration drilling on the recently-announced Sunnyside property has commenced and results are expected to be made available in the coming weeks
 

Piedmont Lithium Limited (“Piedmont” or “Company”) is pleased to advise that the Company has completed its Phase 3 Drilling Program and has received assay results from another 26 holes from its Core property in the Carolina Tin-Spodumene Belt (“TSB”) in North Carolina, United States. The Company intends to release a maiden Mineral Resource estimate on the Core property in accordance with the JORC Code in the coming weeks.
 
For the Phase 3 program, the Company has completed 124 holes totalling 21,360 meters on its core property. Fifteen remaining holes from the Phase 3 campaign have assays pending.
 
Operational efficiencies during the Phase 3 drilling budget allowed the Company to exceed the planned meterage of 20,000 meters by 1,360 meters and will allow for initial drilling on the Sunnyside and Central properties (see Table below).  The necessary state permits have been received and drilling is underway at the Sunnyside Property with one hole completed.  Results of drilling in these exploratory areas will be released in the coming weeks.
 
Keith D. Phillips, President and Chief Executive Officer, said, “Drilling on the core property is now complete and we look forward to issuing our maiden Mineral Resource estimate in the near future, accompanied by a revised exploration target.  Additionally, we are excited about the exploration drilling that has commenced at Sunnyside and hopeful that we will identify significant resource upside on that property.”

Phase 3 Results and Discussion
 
The Phase 3 drilling campaign has consisted of infill drilling along the trends defined by the Phase 2 program and exploratory drilling of targets with little or no prior drilling. Of the 26 holes in this release (holes 187, 189, 190 and 209 - 231), twelve are classified as exploratory, whereas the other 14 holes are part of the infill drilling required for the compilation of the maiden Mineral Resource estimate. These results (Appendix 1) are consistent with Phase 2 results and are currently being added to the geological and resource models.
 
Infill drilling along the eastern portion of the property has confirmed multiple mineralized pegmatite dikes as shown in cross section below.

The twelve exploratory holes tested five areas, the most significant being hole 18-BD-228 which was drilled 175 meters southwest of the last known mineralization on the western trend.  This hole intercepted a single dike of 20.35 meters @ 1.61% Li2O.  The hole had to be abandoned in mineralization due to technical difficulties.  Holes 18-BD-228 and 227 (16.63 meters @ 0.88% Li2O which included 6.39 meters @ 1.56% Li2O) potentially extend the western mineralized zone for another 260 meters southwest.
 
Holes 18-BD-224, 225 and 229 were classified as exploration holes; all three intersected significant mineralization that extends the western zone at depth.  See Appendix 1 for significant reported intercepts.
 
Holes 18-BD-210 and 215 targeted a sub-crop surface showing which had yet to be drilled.  Hole 18-BD-210 intersected a significant thickness of highly weathered pegmatite which returned very low values.  Subsequently, Hole 18-BD-215 was designed to intersect the dike at an increased depth which yielded 16.13 meters @ 0.47% Li2O.  Although low grade this is significant as a new mineralized dike has been identified which has had no exploration to date.
 
As of this release, assays have been released (in this release or prior releases) for 109 of the 124 Phase 3 drill holes.  The fifteen remaining holes are all classified as exploration holes with assays pending.  The majority of outstanding holes are located south western portion of the eastern trend, these holes have the potential of extending the eastern zone for another 300 to 400 meters southwest.

About Piedmont Lithium
 
Piedmont Lithium Limited (ASX: PLL; Nasdaq: PLLL) 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 the 1950s and the 1990s.  The TSB has been described as one of the largest lithium provinces in the world and is located approximately 25 miles west of Charlotte, North Carolina.  It is a premier location to be developing and integrated lithium business based on its favourable geology, proven metallurgy and easy access to infrastructure, power, R&D centres for lithium and battery storage, major high-tech population centres and downstream lithium processing facilities.
 
Piedmont Lithium Location and Bessemer City Lithium Processing Plant (FMC, Top Right) and Kings Mountain Lithium Processing Facility (Albemarle, Bottom Right)
 
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 within the TSB and developed and continue to operate the two world-class lithium processing facilities in the region which were the first modern spodumene processing facilities in the western world. 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.
 
Piedmont, through its 100% owned U.S. subsidiary, Piedmont Lithium Inc., has entered into exclusive option agreements and land acquisition agreements with local landowners, which upon exercise, allow the Company to purchase (or in some cases long-term lease) approximately 1,200 acres of surface property and the associated mineral rights.

Appendix 2: JORC Table 1 Checklist of Assessment and Reporting Criteria
 
Section 1 Sampling Techniques and Data
 
 
Criteria
 
JORC Code explanation
   
Commentary
 
 
Sampling
techniques
 
>  Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as downhole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling.
 
>  Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
 
>  Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information.
   
All results reported are from diamond core samples. The core was sawn at an orientation not influenced by the distribution of mineralization within the drill core (i.e. bisecting mineralized veins or cut perpendicular to a fabric in the rock that is independent of mineralization, such as foliation). Diamond drilling provided continuous core which allowed continuous sampling of mineralized zones.  The core sample intervals were a minimum of 0.35m and a maximum of 1.5m for HQ or NQ drill core (except in saprolitic areas of poor recovery where sample intervals may exceed 1.5m in length) and took into account lithological boundaries (i.e. sample was to, and not across, major contacts).
 
Standards and blanks were inserted into the sample stream to assess the accuracy, precision and methodology of the external laboratories used. In addition, field duplicate samples were inserted to assess the variability of the mineralisation., The laboratories undertake their own duplicate sampling as part of their internal QA/QC processes. Examination of the QA/QC sample data indicates satisfactory performance of field sampling protocols and assay laboratories providing acceptable levels of precision and accuracy.
 
 
 
Drilling
techniques
 
>  Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc.).
   
All diamond drill holes were collared with HQ and were transitioned to NQ once non-weathered and unoxidized bedrock was encountered.  Drill core was recovered from surface.
 
Oriented core was collected on select drill holes using the REFLEX ACT III tool by a qualified geologist at the drill rig. The orientation data is currently being evaluated.
 
 
Drill sample
recovery
 
>  Method of recording and assessing core and chip sample recoveries and results assessed.
 
>  Measures taken to maximise sample recovery and ensure representative nature of the samples.
 
> Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.
   
The core was transported from the drill site to the logging facility in covered boxes with the utmost care. Once at the logging facility, the following procedures were carried out on the core:
 
1.    Re-aligning the broken core in its original position as closely as possible.
 
2.    The length of recovered core was measured, and meter marks clearly placed on the core to indicate depth to the nearest centimetre.
 
3.    The length of core recovered was used to determine the core recovery, which is the length of core recovered divided by the interval drilled (as indicated by the footage marks which was converted to meter marks), expressed as a percentage. This data was recorded in the database. The core was photographed wet before logged.
 
4.    The core was photographed again immediately before sampling with the sample numbers visible.
 
Sample recovery was consistently good except for zones within the oxidized clay and saprolite zones.  These zones were generally within the top 20m of the hole.  No relationship is recognized between recovery and grade.  The drill holes were designed to intersect the targeted pegmatite below the oxidized zone.
 
 
Logging
 
> Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.
 
> Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography.
 
> The total length and percentage of the relevant intersections logged.
   
Geologically, data was collected in detail, sufficient to aid in Mineral Resource estimation.
 
Core logging consisted of marking the core, describing lithologies, geologic features, percentage of spodumene and structural features measured to core axis.
 
The core was photographed wet before logging and again immediately before sampling with the sample numbers visible.
 
All the core from the 26 holes reported was logged.

Sub-sampling
techniques and
sample
preparation
 
> If core, whether cut or sawn and whether quarter, half or all core taken.
 
> If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry.
 
> For all sample types, the nature, quality and appropriateness of the sample  preparation technique.
 
> Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.
 
> Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling.
 
> Whether sample sizes are appropriate to the grain size of the material being sampled.
   
Core was cut in half with a diamond saw.
 
Standard sample intervals were a minimum of 0.35m and a maximum of 1.5m for HQ or NQ drill core, taking into account lithological boundaries (i.e. sample to, and not across, major contacts).
 
The preparation code is CRU21 (crush to 75% of sample <2mm) and PUL45 (pulverize 250g to 85% <75 microns).
 
A CRM or coarse blank was included at the rate of one for every 20 drill core samples (i.e. 5%).
 
Sampling precision is monitored by selecting a sample interval likely to be mineralized and splitting the sample into two ¼ core duplicate samples over the same sample interval. These samples are 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
 
Samples were numbered sequentially with no duplicates and no missing numbers. Triple tag books using 9-digit numbers were used, with one tag inserted into the sample bag and one tag stapled or otherwise affixed into the core tray at the interval the sample was collected. Samples were placed inside pre-numbered sample bags with numbers coinciding to the sample tag. Quality control (QC) samples, consisting of certified reference materials (CRMs), were given sample numbers within the sample stream so that they are masked from the laboratory after sample preparation and to avoid any duplication of sample numbers.
 
 
Quality of assay
data and
laboratory tests
 
 
 
> The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.
 
>  For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.
 
>  Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.
 
   
All samples from the Phase II and Phase III drilling were shipped to the SGS laboratory in Lakefield, Ontario.
 
The preparation code was CRU21 (crush to 75% of sample <2mm) and PUL45 (pulverize 250g to 85% <75 microns).
 
The analyses code was GE ICM40B (multi-acid digestion with either an ICP-ES or ICP-MS finish), which has a range for Li of 1 to 10,000 (1%) ppm Li.
 
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 2017, 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 ¼ 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.
 
                   
 
Verification of
sampling and
assaying
 
> The verification of significant intersections by either independent or alternative company personnel.
 
> The use of twinned holes.
 
>  Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.
 
>  Discuss any adjustment to assay data.
     
Multiple representatives of Piedmont Lithium, Inc. have inspected and verified the results.
 
CSA has conducted multiple site visits. Dennis Arne (Managing Director -Principal Consultant) toured the site, facilities and reviewed core logging and sampling workflow as well as Leon McGarry (Senior Resource Geologist). Each provided comments on how to improve our methods and have been addressed. Verification core samples were collected by Leon McGarry.
 
No holes were twinned.
 
Ten-foot rods and core barrels were used, the core was converted from feet to meters.  Li% was converted to Li2O by multiplying Li% by 2.153.
   
 
Location of data
points
 
>  Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.
 
>  Specification of the grid system used.
 
>  Quality and adequacy of topographic control.
     
Drill collars were located with the Trimble Geo 7 which resulted in accuracies <1m.
 
All coordinates were collected in State Plane and re-projected to Nad83 zone17 in which they are reported.
 
Drill hole surveying was performed on each hole using a REFLEX EZ-Trac multi-shot instrument. Readings were taken approx. every 15 meters (50 feet) and recorded depth, azimuth, and inclination.
   
 
Data spacing
and distribution
 
>  Data spacing for reporting of Exploration Results.
 
> Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.
 
> Whether sample compositing has been applied.
     
For selected areas, the drill spacing is approximately 40 to 80 m along strike and down dip.  This spacing is sufficient to establish continuity in geology and grade for this pegmatite system.
 
Composite samples are reported in Li2O%, this is calculated by multiplying drill length by Li2O for each sample; then the weighted averages for multiple samples are totalled and divided by the total drill length for the selected samples
   
 
Orientation of
data in relation
to geological
structure
 
> Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.
 
>  If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.
     
The pegmatite dikes targeted trend northeast and dip to the southeast, drillholes were designed, oriented to the northwest with inclinations ranging from -45 to -80 degrees, to best intersect the tabular pegmatite bodies as close to perpendicularly as possible.
   
 
Sample security
 
> The measures taken to ensure sample security.
     
Drill core samples were shipped directly from the core shack by the project geologist in sealed rice bags or similar containers using a reputable transport company with shipment tracking capability so that a chain of custody can be maintained.  Each bag was sealed with a security strap with a unique security number. The containers were locked in a shed if they were stored overnight at any point during transit, including at the drill site prior to shipping. The laboratory confirmed the integrity of the rice bag seals upon receipt

> Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.
 
> The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.
   
Piedmont, through its 100% owned subsidiary, Piedmont Lithium, Inc., has entered into exclusive option agreements with local landowners, which upon exercise, allows the Company to purchase (or long term lease) approximately 1199 acres of surface property and the associated mineral rights from the local landowners.
 
There are no known historical sites, wilderness or national parks located within the Project area and there are no known impediments to obtaining a licence to operate in this area.
 
 
Exploration done
by other parties
 
>  Acknowledgment and appraisal of exploration by other parties.
   
The Project is focused over an area that has been explored for lithium dating back to the 1950’s where it was originally explored by Lithium Corporation of America which was subsequently acquired by FMC Corporation. Most recently, North Arrow explored the Project in 2009 and 2010.  North Arrow conducted surface sampling, field mapping, a ground magnetic survey and two diamond drilling programs for a total of 19 holes. Piedmont Lithium, Inc. has obtained North Arrow’s exploration data.
 
 
Geology
 
>  Deposit type, geological setting and style of mineralisation.
   
Spodumene pegmatites, located near the litho tectonic boundary between the inner Piedmont and Kings Mountain belt.  The mineralization is thought to be concurrent and cross-cutting dike swarms extending from the Cherryville granite, as the dikes progressed further from their sources, they became increasingly enriched in incompatible elements such as Li, tin (Sn).  The dikes are considered to be unzoned.

Data
aggregation
methods
 
>  In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated.
 
> Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.
 
> The assumptions used for any reporting of metal equivalent values should be clearly stated.
   
All intercepts reported are for down hole thickness not true thickness.
 
Weighted averaging was used in preparing the intercepts reported.
 
The drill intercepts were calculated by adding the weighted value (drill length x assay) for each sample across the entire pegmatite divided by the total drill thickness of the pegmatite. For each mineralized pegmatite, all assays were used in the composite calculations with no upper or lower cut-offs. Mineralized pegmatite is defined as spodumene bearing pegmatite.
 
Intercepts were reported for entire pegmatites, taking into account lithological boundaries (i.e. sample to, and not across, major contacts), with additional high-grade sub intervals reported from the same pegmatite. In the case where thin wall rock intervals were included, a value of 0% Li2O was inserted for the assay value, thus giving that individual sample a weighted value of 0% Li2O.
 
Cumulative thicknesses are reported for select drill holes. These cumulative thicknesses do not represent continuous mineralized intercepts. The cumulative thickness for a drill hole is calculated by adding the drill widths of two or more mineralized pegmatites encountered in the drill hole, all other intervals are omitted from the calculation.
 
Li% was converted to Li2O% by multiplying Li% by 2.153.
 
 
Relationship
between
mineralisation
widths and
intercept lengths
 
> These relationships are particularly important in the reporting of Exploration Results.
 
>  If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.
 
>  If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’).
   
Drill intercepts are reported as Li2O% over the drill length, not true thickness.  The pegmatites targeted strike northeast-southwest and dip moderately to the southeast.  All holes were drilled to the northwest and with inclinations ranging between -45 and -80
 
 
Diagrams
 
>  Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.
   
Appropriate diagrams, including a drill plan map and cross-section, are included in the main body of this report.
 
 
Balanced
reporting
 
> Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.
   
All of the relevant exploration data for the Exploration Results and available at this time has been provided in this report.
 
 
Other
 substantive
exploration data
 
> Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.
   
Eleven thin section samples were collected and submitted to Vancouver Petrographic for preparation, mineral identification and description.  The Petrographic report identifies the primary mineralogy as quartz, plagioclase (albite), clinopyroxene (spodumene), K-spar and white mica.  Variable amounts of alteration were identified in the pegmatite samples.  One sample of the host rock was submitted and identified as a metadiorite.
 
Thirteen samples from the Phase 1 drilling have been analysed by Semi Quantitative XRD (ME-LR-MIN-MET-MN-DO3) by SGS Mineral Services.  Within all thirteen samples, spodumene was identified.  Spodumene ranged between 5 and 38.6 wt%.  The primary mineralogy of the pegmatite was identified as quartz, albite, spodumene, microcline and muscovite.
 
Bulk Densities are collected from each of the Phase II drill holes (one host rock and one mineralized rock) using analyses code GPHY04V.
 
Composite samples of ore intercepts from the Phase 1 drilling have been submitted to North Carolina State Minerals Research Lab for bench scale spodumene concentrate testing.   Results pending.
 
 
Further work
 
> The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling).
 
>  Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.
   
The Phase II drilling program consisted of 93 holes totaling 12,262m has been completed. After evaluation of all of the Phase II data Piedmont decided to conduct additional Phase III drilling to define the Company’s maiden Mineral Resource estimate in 2018.
