On 12 March this year PREM was granted an Exclusive Prospecting Order (EPO) which gives it's Zulu project in
Zimbabwe a new License Area (LA) of 20,200 hectares. That’s an increase over and above it’s old LA
from
350 hectares to 20,200 hectares which is an enormous
5700% increase. An area that could potentially make Zulu one
the largest Lithium mines of it’s kind on earth. It’s the equivalent
of :-
* 20,000 rugby pitches
* 25% bigger than Liechtenstein
* 25% bigger than Washington DC

Most
genuine shareholders know that Zulu’s LA is huge and the notional
Return On Investment could be good. But just how good isn't easy to
visualize at this early stage.
So let's consider a few things to see if they help.
Zulu’s Lithium
Zulu's
Scoping Study (SS) or PEA, if you prefer to call it that, prepared by
BARA Consulting some years ago helps and it gives some pointers that are
extremely useful.
But although the PEA laid a marker in the sand it gives very little
guidance on scale and potential which is what investors are
understandably very interested in.
BARA
prepared a statement of fact on a fully SAMREC compliant but relatively
very short length of just one of the known lithium strikes on old LA.
That's all they were
remitted to do back then. Consultants like BARA aren’t given to
speculation or vision. They have to be “mechanical” and deal with what
they're asked to do. So BARA put together their SS and designed a
business model for a small mine and no more.
Read Scoping Study RNS here
So
BARA’s appraisal and model were based upon just 15% of one known strike
which was just a small fraction of what has been identified through
subsequent drilling just
on the old LA. It follows therefore that BARA’s business model must be
minimalist and it should be read in that light.
So
PREM used the SS as a basis to estimate an overall resource on the old
LA of 350 hectares. PREM made their estimate known to shareholders at
the time saying it was
an estimate and should be used for guidance only. But what PREMs
estimate did for the first time was to give an indication of scale much
better than the SS. It incorporated drill results subsequent to the SS
and shouldn't therefore be considered as simply
as a guess. It was much more accurate and scientific than that.
If anything, PREMs estimate was more likely to be conservative than not
at that point.
Later still in
the drilling campaign PREM undertook further drilling
maily to delineate newly discovered strikes that appeared to run on to
the old LA boundaries and beyond across the EPO area. I believe those
findings are just drillers notes and assays so far and
were
neither
disclosed or included in PREMs estimate. To get a better idea of the
effect of scale here's some benchmarking and calculations of my own. If I
am anywhere
near right the results are simply breathtaking!
Based
on its old LA PREMs highest target resource was 60mt's of Pegmatite
containing Li2O at an average grade of 1.06%. It’s been found there
mostly in Petalite and Spodumene
form at a ratio of one third to two thirds. Spodumene being the most
attractive of two given its use in battery production in increasingly
strong market conditions.
PREM
derived its estimate from the known and measured strike contained in
the SS and extrapolated it on a straightforward linear basis to
incorporate all the results
from the drilling campaign. After this exercise there were further
lithium strikes found in step out zones when the drilling continued
purposely to delineate the overall potential there. Those up to the
boundaries are sure to have helped to justify PREMs perseverance
in the EPO application.
One of the strikes discovered during this last phase was simply an extension to the main strike. But there were three further strikes discovered and these were categorized as Step Out Zones which were entirely separate to the main strike. These were appropriately called SOZ's 01 to 03.
The Pegmatites in SOZ's 01 to 03 were shown to contain predominantly very high grade Li2O in Spodumene with very little Petalite and Lepidolite encountered. Highly encouraging as it affacted the sites proportionality and potential as well as improving the average grade of 1.06%.
Assay results from ZDD-45 were particularly noteworthy if not world beating where a length of the core was found to contain a bonanza grade in excess of 4% Li2O. George Roach is quoted as saying in an RNS at the time "Not often is a grade of 4.24% Li2O seen in drill core". An understatement if ever there was one.
So
let's assume the 160mt's estimated resource is about right. LCE prices
are currently about $12k/t and rising under improving market conditions
is much much stronger
than the last rally that saw the LCE price top $20k/t. Nothing is for
certain but in my view I doubt we’ll see those all time highs lasting
very much longer.
The
conversion factor from Li2O to LCE is x 2.473. So for ease of maths
let's say the current Li2O price is $30k/t. That would give Zulu an
“in-ground” value of 160m
x 1.06% x $30k which is $51bn. It’s worth reiterating as I've used it
later, so $51bn! But that is based on the old area of 350 hectares. So
now multiply that by 57 and you get to a mind-blowing
$3 trillion in ground value just for the Lithium assuming the
density of Li2O is consistent across the EPO all at today’s prices! If
you think that’s far fetched you should note that an as yet unmeasured
surface Lithium strike
has been found that runs virtually the full length of the EPO. so
roughly 20km. To me it’s inconceivable that that’s the extent of it.
There’s sure to be many more strikes and step out zones than a simple
walk over has detected.
The
largest hard rock lithium resource in the world is owned by AVZ
Minerals in the Democratic Republic of the Congo and it’s resource there
was increased to over 400mt's
@ 1.66% Li2O giving it an ”in ground” value of $200bn on the same
basis. So compare that to the Zulu potential of
$3 trillion in ground value. Amazing!
Zulu
is also often benchmarked against Pilbara's mine in Australia given
it's of a similar size with similar grades. But Pilbara’s development is
ahead of Zulu and it’s
in production now. It's resource is 216mt's @ 1.13% Li2O or something
like that, giving an “in ground” value around $70bn. It’s considered to
be amongst the largest hard rock lithium mines in the world and whatever
anyone might say it’s certainly no whip in
the wood!
If you take Zulu as having an “in ground” value of over $3 trillion it’s
potentially fifteen times higher than one of the largest mines of it's kind currently in the world and
forty times higher in value than Pilbara. All of a sudden Pilbara
starts to take the size of a minnow such is the potential of Zulu!
Some
like to value mines based on the value “in-ground“. It’s a quick and
easy way and it’s a method adopted quite often. We’ve seen George Roach
do it a few times too,
but being honest I'm not a fan of this valuation method.
There
are better ways to value Zulu of which benchmarking, NPV and using an
earning metric are most common. However, now I've mentioned the “in
ground “ values it's just
worth saying that using a factor of 1.5% to calculate Zulu's Market
Cap. Based on the new area under licence and LCE at its current price of
$12k/t would be around $3.6bn. However if LCE were to be more like
$20k/t which I think is more realistic
Zulu's Market Cap would be nearer $6bn.
All
very interesting. As is the fact that Zulu’s Lithium is very high
quality much higher than that of AVZ and Pilbaras. It has a very low
iron content too which sets
it at a cost advantage above most of its peers in the space and highly
sought after by battery manufacturers for all industries not just EV’s
come the day.
These
mines are massive and highly profitable by any measure even at today's
LCE and Spodumene prices. Pilbara's mining plan is to develop it’s mine
in two phases. Phase
1 sees it producing over 300kt’s/ annum of battery grade Spodumene from
a mining rate of 8mt’s and Run Of Mine rate of 2mt's a year. In phase 2
Pilbara intends to have two production areas and double it’s metrics.
It’s Market Cap from producing 300kt’s of
Concentrate per year currently is around $1.2bn with it’s All in Costs
likely to be higher than Zulu's. Adjusted for price increases and the
ramp up in Phase 2 Pilbara is set to achieve a market Cap of around $5bn
in two years time.
As
I see it, Pilbara's plans have been well laid out by experts in the
space and as I see it there's no reason why PREMS plans for Zulu
shouldn't follow suit. On the
other hand, given its potential it’s possible we'll see Zulu have its
own dedicated chemical plant in time producing Lithium in Carbonate
form. For the purposes here I'm going to ignore the Carbonate option for
now. So please bear that in mind. I’ve tried
to be conservative in other areas but in my view they’re factors that
shouldn't be ignored and left unconsidered
Battery
grade Spodumene was selling for around $900/t & $1000/t during the
last bull run when the market price for Lithium Carbonate Equivalent was
around $10,500/t.That’s
reflected in the BARA report too. So projected prices then say $1500/t
for Zulu's Spodumene and $20k/t for LCE seems reasonable.
If
I count the Petalite and Tantalum I'll ramble on forever and it's going
to make the maths quite difficult to follow. So I've assumed they
cancel each other out and
ignored them. I think it's a reasonable assumption and conservative
too. I say that because of the strong Petalite market and the Tantalum
we know is present in grades of up to 200ppm.
I've
also used Zulu’s SS and Prospects Arcadia Mine in Zimbabwe where I can
for references to make my statements and calculations more factual and
less “dreamy”. There
are some key non-disclosures on their offtake agreements in Prospects
presentations which is a shame but understandable for confidentiality.
So the information is limited.
Prospect
hasn't long entered into a seven year offtake agreement with Sinomine, a
Chinese offtaker on a build and transfer basis. Sinomine has agreed to
design and build
the mine but then transfer ownership of it to Prospect in a share swap
arrangement of $10m for 10% stake and an offtake agreement for 70% of
the lithium Concentrate produced for the next six years.
Prospect
has a say in the mine's design and takes ownership of it when it's
built. They pay for it’s cost over a three year payback period I
believe. It sounds like a
good arrangement but Sinomines payment rates under the agreement are
undisclosed so I can’t be entirely sure.
Now
here's an interesting part. Prospect has the right under the agreement
to divert up to 50% of their Concentrate at any time to an owned
Carbonate plant. That is a
step change for them given they've got the room on site. Their licensed
area is 4 x the size of Zulu’s old LA.
Arcadia
managed to start production within a year from a “spade in the ground”
which is very quick especially considering the climatic conditions.
Their plan was to produce
200 kt's/annum of Lithium Petalite Concentrate and over 150kt’s of
Spodumene Concentrate initially and whilst those targets may have been
met they’ve just opened a chemical plant too and are now producing
Carbonate too.
The
Arcadia mine in Zimbabwe is said to be one of a group of mines that are
the largest hard rock Lithium mines in the world. At 0.2% cut off I
think they have a resource
of about 75mt's at similar grades to PREM. To put that into perspective
Zulu has an assessed but well estimated target of twice that on just on
it’s old LA. Like all appraisals, logistics should be considered. It
will be the pinch point for Zulu in my view.
I doubt we will be able to ship much more than 300kt's - 350kt’s/annum
by road from each mine gate.
So with my positive hat on I like to imagine Zulu in 3 phases:-
PHASE 1 DFS
-
I think Zulu could command a $200m to $300m Market Cap just on it’s
Lithium alone at this stage or more subject to reasonable fundamentals
which I'm confident
we'll see given the market outlook. If there are offers from suitors at
this point Zulu’s value could be substantially more and I see that as a
real possibility.
I've
derived the basic value from Prospects' deal with Sinomine where it was
given a similar value in the same time & space. So if we say PREM
has 20bn shares in issue
then we get to a share price contribution of around 1.25p to
PREM. Fairly straightforward. But I say again just on the Lithium asset.
PHASE 2 PRODUCTION
-
Zulu should be producing Lithium Concentrate. $120m Capex or
thereabouts will be needed to build a Concentrate facility. So we should
expect something like a
25% dilution to raise Capex finance in a 50/50 debt to equity
fundraise.
Zulu
should achieve a rate of 2m/t ROM/annum @1.06% Li2O grade quite easily
and similar to it’s industry peers. That would produce 300kts - 350kt’s
>6% Spodumene at a
quality better than battery grade. With a $1.5k/t offtake agreement
that would give Zulu a $450m/annum revenue. C3 costs or All In Costs if
you prefer from the BARA report should be no more than $550/t or $165m
annualised. So assuming conservatively = Tantalum
credit at 60 ppm grade should cover most of those. "Earnings' '
therefore would be in the region of $375m giving Zulu's notional Market
Cap of $3.75bn using a P/E ratio of 10 in an earnings metric
calculation. In turn a contribution then to PREMs Market Cap
of around $3bn say. PREM having retained 75% ownership. All this is
very much in line with Pilbara’s appraisal.
PREM
currently has 20bn shares issued or so but by then say 30bn. Based on
that Zulu’s Lithium mine should contribute roughly 8p to PREMs SP at
current exchange rates.
PHASE 2a
INCREASED PRODUCTION -
The
same as Phase 2 but double the metrics. Production being from two
locations within the EPO and the mine having two gates to ship it’s
Concentrate from in lieu
of one.
PHASE 3 BEYOND
2028 -
Zulu could be one of the largest producing Lithium mines from a hard
rock source in the world producing Lithium Carbonate. At least $500m
Capex is going
to be needed to build a chemical plant capable of producing 80kt's to
100kt's of Carbonate. I see most of that being funded out off WIP though
with very little or no dilution or debt.
Projected
revenue from the sale of 80kt's Carbonate should be near $1.6bn/annum
and projected All In Costs should be around $5k/t so perhaps
$400m/annum. The cost figures
have come from benchmarking against Zulu's peers.
With
earnings then of $1.1bn the math tells us we're looking at a Market Cap
of $10bn and therefore a contribution to PREMs SP of 33p or
thereabouts. I said at the beginning
of this the figures would be breathtaking and I think that one
certainly is! Whilst PREMs notional Market Cap wouldn’t be the highest
in the Lithium space most but not all of the others are miners
processing the metal from solution rather than hard rock.
It's
worth reiterating that the figures I’ve arrived at for the Concentrate
alternative are projected three years out for Phase 2 and those for the
Carbonate alternative
are projected six years out. We could well be looking at a huge mining
operation in Zulu, with it being quite possibly the largest of its kind
in the world.
Zulu’s Gold
In
1994 The British Geological Survey organisation undertook a very
detailed Technical Review of Zimbabwe's gold mines. It considered
eighteen mines in total and nine
of those in far more detail than the others.
The
nine were in the Greenstone belt that crosses Zulu's EPO. Although in
part only it looks to be very extensive covering what looks like roughly
two thirds of it. It's
difficult to be more precise at this stage.
To
paint a picture the Greenstone belt in Zimbabwe is massive by any
measure and should only be categorised in square miles. It really is
that big and it’s largely unexplored.
What is known for certain however is that it's the richest belt in gold
resources on earth.
The
old mines that are littered in the belt are mostly disused now. They
were abandoned in an undepleted state in the 1930's as we're most mines
at the time I believe.
The average Au grades identified by the BB'S were consistent and nothing short of jaw dropping!
One
large mine had just a small quantity of it’s resource less than 5g's/t
Au the rest was over. One had a large quantity of Au over 20 g's/t and
the rest of the mines
had between 7 & 8g's/t. All of these were either at the surface or
at shallow levels lending them to open pit mining.
Zulu’s
gold potential is much bigger than this but simply run an appraisal
using a modest 80k oz’s production rate to give you an idea. So annual
revenue would be around
$150m at today's prices, All In Costs at the grades I’ve said should be
no more than $500/oz and the annual net profit would be around $120m.
Apply then an earnings metric calculation using a p/e of say 15 and you
get a Market Cap of $2bn. As I say though
this could be conservative especially given Au has a very positive
outlook just now.
Finding another Au resource on earth that has near surface grades like these and has this potential is a real challenge .
CONCLUSION
My conclusion is that
Zulu's gold potential may be even bigger than its Lithium. Regardless,
neither cannot and should not be ignored.
If I'm anywhere near right, PREM has a truly valuable asset in Zulu within its portfolio.
One
which could easily have a Market Cap of $10bn in five years time if not
more! I’ve appraised Zulu’s Lithium and gold values using four
recognised methods. An in ground
valuation. One using benchmarking. An NPV25, although I haven't given
the details, and one using an earnings metric. They're all slightly
different, but all are mind blowing!
I'm
not going to give any investment advice here. I think with PREMs
current Market Cap of $60m we could be looking at a 200 bagger on that
metric within five years.
What
I would say though is you don’t want to miss an opportunity with this
potential so you definitely should DYOR before dismissing it. It is also worth bearing in mind this is only one of PREM's assets, with the others being RHA Tungsten, Circums Mineral Potash, MNH Manganese, Ligonha Gold, Katete REE, Tinde + more!
