Kore Potash Plc
("Kore Potash" or the "Company")
Significant Extensions to Kore's Existing Sylvinite Deposits
Expected
Kore Potash plc (ASX: KP2, AIM: KP2, JSE: KP2) the potash
development company whose flagship asset is the 97%-owned
Sintoukola Potash Project in the Republic of Congo, is pleased to
provide Exploration Targets for potential extensions of the Kola
and Dougou Extension sylvinite Deposits, reported in accordance
with the JORC Code (2012 edition). These Exploration Targets have
been identified as part of the work program to improve the
Company's understanding of both the potential scale and the
strategic opportunities presented by the multiple occurrences of
potash in the Sintoukola Project area.
An Exploration Target is not a Mineral Resource but a statement
of exploration potential and in this case, is based on drilling and
2D seismic survey data and the Company's understanding of the
controls on sylvinite mineralisation.
Highlights
-- Potential identified to increase the Company's sylvinite
Deposits to a total of between 1.5 and 1.9 billion tonnes (Bt) of
sylvinite with an average grade of between 34 and 37% KCl
-- The Exploration Targets are as follows and provided in Table 1 and located on Figure 1
o 'Kola South', the potential southward extension to the Kola
Deposit
-- 95 to 175 Mt
-- average grade of between 34 and 42% KCl
o 'DX North', the potential northward extension to the Dougou
Extension Deposit
-- 320 to 600 Mt
-- average grade of between 30 and 38% KCl
-- The potential quantity and grade of an Exploration Target is conceptual in nature and is an approximation. There has been insufficient exploration at Kola South and DX North to estimate
-- Mineral Resources and it is uncertain if further exploration
will result in the estimation of Mineral Resources
-- The Exploration Targets are immediately adjacent to the
Company's existing sylvinite Mineral Resources which total 1.08 Bt
with an average grade of 35.5% KCl at the Kola and Dougou Extension
Deposits
-- The Exploration Targets are within 40 km of the Company's
proposed processing and export facility (Figure 3).
-- Insoluble content of the sylvinite within the Exploration
Targets is expected to be <0.5% which is extremely low compared
to potash industry averages
Brad Sampson, CEO of Kore, commented:
"Quantifying the potential scale of the Sylvinite and Carnallite
deposits of the Sintoukola project area is important. It positions
the Company to assess the strategic options available for these
world-class, shallow and high-grade Potash deposits while
continuing to allow flexibility on the best development pathway for
this globally important Potash province."

Sylvinite is a rock type comprised primarily of the potash
mineral sylvite (KCl), and halite (NaCl) and is the most important
source of potash globally.
Existing sylvinite Mineral Resources
The location of the Kola and Dougou Extension sylvinite Deposits
are shown in Figure 1 and 3, along with the adjacent Exploration
Target areas (or 'target areas'). A table including the existing
sylvinite Mineral Resource estimates is provided below this
announcement, reported according to JORC 2012. Kola hosts a
Measured and Indicated sylvinite Mineral Resource totalling 508 Mt
with an average grade of 35.4% KCl (Company announcement dated 6
July 2017). Dougou Extension hosts an Indicated and Inferred
sylvinite Mineral Resource totalling 232 Mt with an average grade
of 38.1 % KCl (announcement dated 20 August 2018).
Overview of the Geology
The potash at the Kola and Dougou Extension is hosted by
sub-horizontal or gently dipping layers or 'seams' within the upper
part of a 400-500 m thick 'Salt Member' ('the Salt') of the Lower
Cretaceous-aged Loeme Evaporite formation (Figure 2). The evaporite
rocks extend from approximately 50 km inland to over 200 km
offshore and is comprised of up to 11 'cycles' which can be
correlated across the onshore part of the basin. The existing Kola
and Dougou Extension Deposits are large, occupying areas several km
across and in length. At Kola the Salt is covered by 180 to 280 m
of sediments referred to as the 'Cover Rocks'. At Dougou Extension
the Cover Rocks are between and 290 and 420 m thick. The Salt is
overlain by a 5-20 m thick aquitard, referred to as the Anhydrite
Member. The base of this unit (the top of the Salt) is an
unconformity, so that the upper parts of the Salt are variably
preserved or truncated by this contact.
At Kola and Dougou Extension, the sylvinite formed by the
replacement of pre-existing carnallitite of 1 or 2 of the four
seams in the upper Salt cycles. Carnallitite is a relatively
low-grade potash rock comprised primarily of the mineral carnallite
(KMgCl3--6H2O) and halite (NaCl). The seams are as follows; the Top
Seam (TS), the Hangingwall Seam (HWS), the Upper Seam (US) and
Lower Seam (LS) separated by rock-salt (Figure 2). At Kola the TS
is mostly absent due to it being truncated by the unconformity at
the top of the Salt so does not form part of the Mineral Resource
or Exploration Target. At Dougou Extension the TS is 12-15 m above
the HWS and is widely preserved, hosting the bulk of the sylvinite
Mineral Resource. At both Deposits internal zones of carnallitite
occur, and this is not mixed with the sylvinite, always being
lateral or below the sylvinite with abrupt contacts between the
two.
The extent of the Kola South and DX North Exploration Targets is
controlled by the extent of broad structural 'highs' (100's m)
beneath or adjacent to them (Figure 1). In these areas the process
of sylvinite replacement was 'promoted' in the upper 10-90 m of the
Salt. These structural features pre-date the Salt and had an
influence on the formation of sylvinite.
Fundamental to the Exploration Targets is the well-established
continuity of the evaporite layers, including the potash seams.
Each seam, regardless of whether it is sylvinite or carnallitite
can be correlated over tens of kilometres relating to the
continuity of the original depositional setting of the evaporite.
Lateral grade variation of the sylvinite of each seam and the
content of insoluble material is low for the same reason. The HWS
is the highest grading seam, where sylvinite grades up to 62% KCl
at the Kola and Dougou Extension Deposits. The US, then the TS and
LS, have grades between 24 and 42% KCl.
The Kola South Exploration Target
The intersections of sylvinite in two of the Company's
drill-holes completed in 2017 provide support for the Kola South
Exploration Target and were reported previously along with Table 1
of the JORC Code (Company announcement dated 7 December 2017).
These holes, EK_53 and EK_54, intersected sylvinite in the HWS
grading 61.9 and 60.0 % KCl over a thickness of 2.22 and 3.26 m
respectively.
Based on EK_53, EK_54 and available historic seismic data, the
sylvinite at the Kola deposit is likely to extend up to 7 km
southeast of the current Inferred Resource extent (Figure. 1) and
the sylvinite mineralised zones are likely to be contiguous with
that of the current Mineral Resource. The extent of the prospective
area is controlled by a subtle structural 'high' below the Salt
Member, extending southwards on strike from the Kola deposit. This
'high' is evident on the plot of the thickness of the Salt Member
(Figure 1). Seismic survey data also guides the overall geometry of
the Salt and suggests that there are no features disrupting the
Salt stratigraphy within the target area.
In determining the Exploration Target, the average expected
thickness of the HWS was determined from the EK_53 and EK_54
intersections, both of which are sylvinite. In these holes the US
and LS is carnallitite, but it is expected these seams will be
sylvinite over significant portions of the target area, as is the
case at the Kola Deposit. The thickness of the US and LS for the
Exploration Target was determined from the data for these seams at
the Kola Deposit, with a slight reduction to the LS thickness (to
account for a slightly thinned LS carnallite seam in EK_54). The
grade range of the seams was determined from the large amount of
data for the seams at Kola, along with the intersections in EK_53
and EK_54 for the sylvinite HWS. For each seam, the minimum grade
was guided by the 10(th) percentile of the grade data for all
existing intersections and the maximum was assigned to less than
the 80(th) percentile, considered appropriate as low or high-grade
outliers do not exist.
Based on the understanding on the distribution of sylvinite at
the Kola Deposit, a minimum and maximum 'abundance' of each of the
seams was developed for Kola South, expressed as a percentage of
the prospective area (Table 1). It is expected that sylvinite of
the US will contribute most to the potential tonnage, followed by
the LS and HWS in roughly equal proportions. The predicted
abundance of the HWS is greater than at the Kola Deposit,
reflecting the expectation that it is less widely truncated (by the
unconformity at the top of the Salt) at Kola South.
The DX North Exploration Target
This is the potential northward extension of the recently
announced Dougou Extension Deposit (Company announcement dated 20
August 2018). The prospective area is defined by slight elevation
and thinning of the Salt where the rocks (100's m) below the Salt
are affected by horst development within an area referred to as the
Yangala High (Figure 1), and northwards of this feature adjacent to
the basin margin. The delineation of the prospective zone was based
on a large amount of historical 2D seismic survey data and several
historical drill-holes (Figure 1). Appendix 1 contains the JORC
2012 Table 1 for exploration data relating to the DX North
Exploration Target, having not been part of previous announcements.
Table 3 provides summarises of potash intersections in the historic
drill-holes. The Company's 2017 drill-hole DX_05 planned to test
the DX North area east of historic hole Yangala-1 but stopped short
of the Salt Member due to drilling difficulties.
The estimation of the Exploration Target range of tonnes for DX
North is based on the assumption that a portion of the total area
of each seam will host sylvinite, in the proportions provided in
Table 1. There is less supporting data in relation to the size of
the target area than for Kola South; this lower level of confidence
is reflected in the maximum assigned proportions. It is expected
that in some areas the seams are either truncated by the
unconformity at the top of the Salt or are present but are
carnallitite but that the material quantified by the Exploration
Target would be within areas that are sufficiently extensive and
continuous to be potentially amenable to economic extraction.
Historic drill-hole Yangala-1 contains sylvinite in the TS, US
and LS but are partially leached so that grade is likely to be less
than what is typical for these seams. This is encouraging as it
shows that the process of sylvinite formation has taken place well
into the Salt. The Historic hole Maf-1 (Figure 1) intersected a 4.1
m thick sylvinite seam, interpreted to be the US or LS. Hole TK-1
contains carnallitite in the TS, HWS, US and LS.
The average thickness of the seams in the DX North area were
determined from the sylvinite intersections of the TS and HWS in
the Company's drill-holes at the Dougou Extension Deposit. The
thickness of the sylvinite US and LS was estimated based on the
thickness of the carnallitite intersections in the area, as this is
proportional to the thickness when replaced by sylvinite. The grade
range for the HWS and TS is based on the intersections at the
Dougou Extension Deposit. The grade range for the US and LS is
based on the grade of these seams at Kola. API values of >300
API in hole Maf-1 provide support for the presence of high-grade
sylvinite. As at Kola South, the 10(th) and 80(th) percentiles of
grade data in the supporting intersections was used to guide the
minimum and maximum stated grade of the Exploration Target.

Further Exploration Work
No immediate follow up exploration activity is currently planned
while the Company is focused on the review of the Kola Definitive
Feasibility Study. The following provides an indication of what
work that would typically be required to advance the Exploration
Targets.
-- Acquire additional 2D seismic survey data on wide-spaced
lines (1-3 km apart) to improve the geological model and
understanding of the Salt Member.
-- Drill 3-5 holes in each target area. At Kola South, holes
would be expected to have final depths of between 300 and 400 m; at
DX North holes up to a depth of 700 m may be required.
-- If this drilling is sufficiently successful, the data may
support expansions of the existing Kola and Dougou Extension
Mineral Resource Estimates.
-- Further 'infill' drilling and seismic surveying may then be required to increase confidence.
-- This programme if commenced may take approximately 12-24 months to complete from initiation.

About Kore Potash's Projects
Kore Potash is an advanced stage mineral exploration and
development company whose primary asset is 97%-owned interest in
the Sintoukola project, a potash project located in the Republic of
Congo. The Sintoukola project comprises the Kola sylvinite and
carnallite Deposits, the Dougou Extension sylvinite Deposit and the
Dougou carnallite Deposit. These deposits are within the Kola and
Dougou Mining Licenses. The Sintoukola project also includes the
Sintoukola 2 Exploration License.
Sintoukola is located approximately 80 km to the north of the
city of Pointe Noire which has a major port facility, and within 30
km of the Atlantic coast. Sintoukola has the potential to be among
the world's lowest-cost potash producers and its location near the
coast offers a transport cost advantage to global fertilizer
markets.
The Kola sylvinite Deposit has a Measured and Indicated
sylvinite Mineral Resource Estimate of 508 million tonnes grading
35.4 % KCl. A Definitive Feasibility Study ("DFS") is being
conducted by a consortium of French engineering and construction
companies. The deposit is 'open' laterally; drill-holes completed
in 2017 intersected high-grade sylvinite several km southeast of
the Deposit. It is shallow relative to most potash mines; the
proposed shaft bottom will be 270 m below surface.
The Dougou Extension sylvinite Deposit contains a total
sylvinite Mineral Resource estimate of 232 Mt grading 38.1% KCl,
hosted by two seams. The Mineral Resource includes 67 Mt grading
60.1 % KCl. Dougou Extension is located 15 km southwest of Kola. A
large zone that is considered prospective for sylvinite extends a
further 25 km northwards, within the Dougou Mining License and the
'Sintoukola 2' Exploration License.
The Kola and Dougou Extension sylvinite Deposits are considered
high grade relative to most potash deposits globally and have the
advantage of having very low content of insoluble material, less
than 0.3% which provides a further processing advantage.
The Dougou carnallite Deposit has a Measured and Indicated
Potash Mineral Resource of 1.1 billion tonnes grading 20.6% KCl (at
a depth of between 400 and 600 metres) hosted by 35-40 metres of
carnallitite within 4 flat-lying seams. A Scoping Study was
completed in February 2015. This Study indicated that a Life of
Mine operating cost of US$68 per tonne MoP was achievable.
-- Muriate of Potash (MoP) is the saleable form of potassium
chloride (KCl), comprising of a minimum 95% KCl.
-- Sylvinite is a rock type comprised predominantly of the
potash mineral sylvite (KCl) and halite (NaCl).
-- Carnallitite is a rock type comprised predominantly of the
potash mineral carnallite (KMgCl(3) --6H(2) O) and halite
(NaCl).

------------------------------------------------------------ --------------------------------------------------------------
2.3. GEOLOGY
* The potash seams are hosted by the Loeme Evaporite
formation, comprised of sedimentary evaporite rocks
with minor clastic layers. This formation is
typically 400-500 m thick These rocks are within the
Congo Basin which extends from the Cabinda enclave of
Angola to southern Gabon, from approximately 50 km
inland, extending some 200-300 km offshore. The
evaporites were deposited during the Aptian epoch of
the Lower Cretaceous, probably between 125 and 112
million years ago, within a sub-sea level basin
following the break-up of Gondwana into the African
and South American continents. Importantly, the
sedimentation was in a post-rift setting leading to
the development of evaporite layers with significant
continuity.
* In terms of classification nomenclature, the
evaporite is of the basin-wide 'mega-halite' type,
formed by the cyclic evaporation of sea-water sourced,
seepage-fed brines in an extensive subsiding basin,
each cycle generally following the expected brine
evolution and resultant mineral precipitation model:
dolomite then gypsum then halite then the bitterns of
Mg and K as chlorides. To precipitate the thick
potash beds the system experienced prolonged periods
within a relatively narrow range of high salinity.
* Reflecting the chloride-Mg-K dominated brine
composition, halite (NaCl), carnallite (KMgCl(3)
--6H(2) O) and bischofite (MgCl(2) --6H(2) O) account
for over 90% of the evaporite rocks. Sylvinite is
found relatively close to the top of the Salt.
Carnallitite is a rock comprised predominantly of
carnallite and halite. Sylvinite is a rock comprised
predominantly of sylvite (KCl) and halite. The term
'rock-salt' is used to refer to a rock comprising of
halite without appreciable other minerals/materials.
* Importantly, bischofite does not occur in the floor
or roof of the TS, HWS, US or LS, only present >40 m
below the LS. This mineral is mechanically very weak
and considered disadvantageous if in proximity to
mine workings.
* The Salt was deposited in a cyclic manner; 10-11
cycles have been recognised, of which most are
preserved at Dougou Extension, the important 'Top
Seam' (TS) and 'Hangingwall Seam' (HWS) potash seams
are within the mid to upper part of cycle 9.
* All layers in the Salt member have good continuity
and the thickness of the interval between them is
consistent. Even narrow mm-scale layers or sub-layers
can be correlated over many km. In most holes all
potash layers are present and have a low angle of dip
(
* The HWS is relatively high grade, being comprised of
a single massive bed of approximately 60% sylvite.
The TS, US and LS are comprised of high grade
sylvinite layers with internal rock-salt layers and
therefore have lower overall grades than the HWS.
* At Dougou Extension and the DX North area, the
evaporite stratigraphy is slightly elevated and
thinned relating to the presence of a horst block
forming a paleo-topographic high in the underlying
pre and syn-rift rocks referred to as the 'Yangala
High'.
* Capping the salt dominated part (Salt Member or
'Salt') is a low permeability layer of anhydrite,
gypsum and clay (the Anhydrite Member). Importantly,
the contact between the Anhydrite Member and the
underlying salt is an unconformity. As the layers of
the Salt are gently undulating and the upper contact
is an unconformity, in some areas there is a greater
thickness of Salt above the seams than in others, or
the seams may be 'truncated'.
* The Anhydrite Member is covered by a thick 'cover
sequence' of carbonate rocks and clastic sediments of
Cretaceous age (Albian) to recent.
* Potash seams were originally deposited as
carnallitite but were replaced in some areas by
sylvinite, by a process of leaching Mg, OH and some
NaCl from carnallite, converting it to sylvite. This
process has taken place preferentially over the
Yangala High, initiating at the top of the Salt
Member. This process is based on observations at the
Kola and Dougou Extension Deposits and is expected
within the DX North target area.
* The thickness of the Salt above the seams is an
important control on the whether the seam is
sylvinite or carnallitite, and thus the extent of the
sylvinite mineralisation. Added to this is the
variation in the depth, from the top of the Salt that
the process has been effective, between 20 and 90 m
at the Dougou Extension Deposit. At the DX North area
it is likely to be variable; the lowermost sylvinite
in Yangala-1 is approximately 155 m below the top of
the Salt which is encouraging.
* It is observed at the Kola and Dougou Extension
Deposits, that the process advanced on a downward
moving 'front' and was efficient; when converted no
residual carnallite remains within the sylvinite.
Un-replaced carnallitite may occur below the
sylvinite (not above it) but the contact is always
abrupt. As a general rule, the conversion leads to a
halving of thickness and a doubling of grade though
this is also influence by the proportion of halite to
carnallite in the original seam.
* Very close to the top of the Salt or locally in areas
of greater structural disturbance, the sylvite may be
partially or entirely leached, leaving reddish
coloured halite with no or residual KCl, referred to
as 'ghost seams' but still identifiable; it is
possible that drill-hole Yangala-1 is in this type of
setting.

Indicated Mineral An 'Indicated Mineral Resource' is that part of a
Resource Mineral Resource for which quantity, grade (or quality),
densities, shape and physical characteristics are
estimated with sufficient confidence to allow the
application of Modifying Factors in sufficient detail
to support mine planning and evaluation of the economic
viability of the deposit. Geological evidence is derived
from adequately detailed and reliable exploration,
sampling and testing gathered through appropriate
techniques from locations such as outcrops, trenches,
pits, workings and drillholes, and is sufficient to
assume geological and grade (or quality) continuity
between points of observation where data and samples
are gathered. An Indicated Mineral Resource has a
lower level of confidence than that applying to a
Measured Mineral Resource and may only be converted
to a Probable Ore Reserve.
------------------------------------------------------------------
Inferred Mineral An 'Inferred Mineral Resource' is that part of a Mineral
Resource Resource for which quantity and grade (or quality)
are estimated on the basis of limited geological evidence
and sampling. Geological evidence is sufficient to
imply but not verify geological and grade (or quality)
continuity. It is based on exploration, sampling and
testing information gathered through appropriate techniques
from locations such as outcrops, trenches, pits, workings
and drillholes. An Inferred Mineral Resource has a
lower level of confidence than that applying to an
