2024 Sanankoro Exploration
Update
Cora Gold Limited, the West African
focused gold company, is pleased to provide an update on recent
exploration work conducted at the Company's Sanankoro Gold Project
('Sanankoro' or the 'Project') in southern Mali.
2024 Exploration Highlights
●
Sampling completed as part of a targeted
exploration programme aimed at identifying priority targets to
expand Sanankoro's current 920koz Resource and Reserve inventory,
which is contained within 5 main deposits (Zone A, Zone B, Zone B North, Zone C and Selin).
●
Identified 4 primary and 4 secondary gold bearing
structures, representing approximately 50km (cumulative strike
length) of highly prospective terrain for exploration
targeting.
●
20 new and existing greenfield exploration targets
now outlined within these 8 gold bearing structures, which are
being ranked to prioritise future drill programmes.

●
Company's geologists are systematically collecting
data and advancing the remaining 13 greenfield targets towards
reconnaissance drill evaluation status.
●
All targets are soft oxide rock and within
trucking distance of the proposed Sanankoro Gold processing
plant.
Bert Monro, Chief Executive Officer of Cora,
commented, "Sanankoro is in its relative infancy as an exploration
project, due to our primary focus to date centring on the
definition of oxide Mineral Resources. We
have had great success in defining a sizeable commercial resource
across the five main deposits known to us (being Zone A,
Zone B, Zone B North, Zone C and Selin) and we are
aware that there is significant exploration endowment at the
property. These 20 new targets are an excellent indication of
Sanankoro's prospectivity and in conjunction with the remaining
untested 50km strike length of gold bearing structures we are very
optimistic that with continued exploration we will be able to grow
our resource base and life of mine."

Regional Geology
On a regional scale, Sanankoro is
characterised by the extensive 500m wide Sanankoro Main Shear Zone
'SMSZ', which is located parallel to the regional fault structure
separating the Siguiri basin sediments to the west and the
Yanfolila belt mixed lithologies to the east. This regional fault
can be traced in excess of 150km in length and serves as a major
fluid conduit along which a handful of significant gold deposits
are located within its close proximity, including Kalana (+2Moz),
Komana (1.4Moz) and Kobada (2.4Moz).
Within the Project area gold
mineralisation is expressed by a large surficial elevated gold
anomaly (>20 ppb Au) of approximately 14km x 3km in geometry,
widespread artisanal mining activity of shallow surface material,
and by more than 155,000m of drilling, of which 100,000m has been
drilled by Cora since 2017.
As a result of the Company's recent
exploration work, it has defined 4 major gold bearing trends within
its permits, of which the SMSZ is the dominant structure (+10km
long and approximately 500m wide) (see Figure 1 for details). Gold
mineralisation at the Project is primarily steeply dipping to the
East and striking to the North-North-East (approximately 010°), a
trend that is consistent with regional structures and gold
mineralised zones within Southern Mali.

2023-2024 Exploration Results Summary
The Company's exploration team has
been actively conducting systematic field exploration activities at
the Project since early 2023. The objective of the exploration work
has been two-fold: i. identify new exploration targets and their
primary controlling structures; and ii. advance known targets to
drill ready status. Both objectives will serve to maximise the
future mine life opportunity at Sanankoro, potentially adding to
the currently defined mineral resources (920koz) at the 5
established deposits and expanding on the existing 6.8 year mine
life (see announcement dated 21 November 2022).
During the past 18 months of
exploration work, the Company's exploration geologists have
identified more than 20 exploration targets within the Sanankoro
exploration permits.

bearing shear zones located within the Sanankoro Gold
Project
The following is a summary of the
main exploration targets, none of which yet have mineral resources
defined.
Berebogoni-Woyodakoun
The Berebogoni-Woyodakoun target
(previously referred to as Bokoro East) is one of the largest and
most promising new exploration targets at the Project. The target
is located south of the established Selin deposit along the Selin
South structure and is a site of active artisanal mining activity.
Current known dimensions of orpaillage workings extend over a
distance of 2.7km in strike (NNE) and up to 150m wide. Gold
mineralisation at Berebogoni - Woyodakoun is hosted primarily by a
stockwork of thin quartz veins within sandstone and tuff. Host
rocks are heavily oxidised and altered, with vugs present due to
oxidation of sulphides, with limonite the dominant form of
alteration.
Recent sampling of the orpaillage
workings has returned grab values including 4.39 g/t Au, 9.64 g/t
Au and 16.5 g/t Au. Best channel intervals include BCH013 6m @ 0.64
g/t Au, BCH014 14m @ 1.26 g/t Au, BCH015 6m @ 1.89 g/t Au, BCH029
8m @ 0.98 g/t Au and BCH046 10m @ 1.42 g/t Au. Limited drilling has
been carried out previously at the target with some 18 shallow
reverse circulation ('RC') holes drilled, which combined with all
other available sample data was modelled by CSA Global (now ERM)
and an Exploration target range of 4.1 - 5.6Mt @ 0.55-1.29 g/t Au
was reported (see announcement dated 7 November 2022). The best
drill intercept reported was in hole BC0111 of 4m @ 7.2 g/t Au.
Hole SC0026 returned 17m @ 1.18 g/t Au and ended in mineralisation,
and 4 other holes also ended in mineralisation, including BC0011 of
7m @ 1.59 g/t Au at 46m. Systematic drilling has not been carried
out to test the full strike length and width of the target
area.
Due to its location between Selin
and the Zone B deposits, the many artisanal excavations not yet
drill tested, and its close proximity to the proposed process plant
site (short trucking distances and therefore lower cut-off grades),
Berebogoni - Woyodakoun is an important target as a source of
potential oxide mill feed for the operation.

Berebogni-Woyodakoun
Dakounkoura and Dakounkoro
The Dakounkoura and Dakounkoro
targets are located at the northern end of the SMSZ, straddling the
footwall (Bokoro structure) and hanging wall (Sanankoro structure)
contacts of the SMSZ respectively. Due to the style of
mineralisation present at both targets, the broad extents of
anomalous and lower grade rock samples, extensive artisanal mining
excavations, and limited drilling carried out, the Dakounkoura and
Dakounkoro targets have the potential to host large mineral
resource tonnages. Further exploration work is due to be carried
out in order to progress these targets towards reconnaissance
drilling.
Sampling of the artisanal miners'
workings has returned grab values including 8.0 g/t Au, 7.4 g/t Au
and 6.0 g/t Au, with many more samples between 0.2-1 g/t Au range
highlighting the broad nature of the mineralised zones (consisting
of quartz stockworking) within the sandstone and intercalated fine
sediment package of rocks. Best channel intervals are 46m @ 0.55
g/t Au from SCH014, 20m @ 0.52 g/t Au from SCH073, 12m @ 0.94 g/t
Au from SCH115 and 15m @ 1.2 g/t Au from SCH130, with many more
higher grade channels sampled but which were narrower due to the
lack of wall rock exposed by the artisanal miners. Many of these
narrower channels either ended or started in mineralisation
(>0.2 g/t Au). Very limited drilling has been carried out at the
2 targets, with only 6 shallow RC holes drilled. The best of these
drill holes is SC0109 26m @ 1.16 g/t Au, SC0203 6m @ 1.67 g/t Au,
and SB0078 18m @ 0.99 g/t Au. An indication of the potential strike
length of mineralisation is hole SC0282, which was drilled 900m
south of Dakounkoura along strike of Zone B North pit, where it
intersected 25m @ 0.94 g/t Au and ended in mineralisation, which if
linked together would provide 1.8km of mineralised strength length.
These two targets of Dakounkoro and Dakounkoura were modelled by
CSA Global (now ERM), which calculated an Exploration Target range
of 5.9-8Mt @ 0.60-1.20 g/t Au, as reported (see announcement dated
7 November 2022).

Dako
The Dako target is located
approximately 8km to the S/E of Zone A, along the NNE trending Dako
shear zone. Recent exploration work continues to confirm the
potential of Dako as an exploration target and possible location of
future mineral resources at Sanankoro. Mineralisation at Dako has a
strike length of 2.4km and is up to 150m wide.
Mineralisation is controlled by the
large Dako shear with cross cutting east-west quartz veins within
local sediment and volcanic units of sandstone and tuff. Best grab
samples to date are 6.58 g/t Au, 5.27 g/t Au, 4.03 g/t Au and 3.84
g/t Au. Dako has more higher grade samples >1 g/t Au than many
of the other Sanankoro targets. Best channel intervals are DKCH007
10m @ 1.12 g/t Au, DKCH008 14m @ 0.75 g/t Au, DCH0042 19.5m @ 1.75
g/t Au and DKCH0029 5.5m @ 9.90 g/t Au. Channel sampling has been
restricted by available wall rock exposure in the artisanal miners'
excavations. Pits have also been used as an effective exploration
tool and due to the thick depth of laterite, anomalous samples
>0.1 g/t Au are a sign of underlying mineralisation in the
saprolite and have assisted in mapping out the underlying structure
for future drilling. 40 shallow exploratory RC drill holes have
been drilled at Dako, with the best holes returning the following
intervals: DC0002 9m @ 1.19 g/t Au and 11m @ 1.15 g/t Au with 3
zones intersected in total by the hole; DC007 12m @ 1.30 g/t Au;
DC0029 22m @ 0.68 g/t Au and 20m @ 0.53 g/t Au; and DC0030 13m @
1.87 g/t Au, with the hole also ending in mineralisation at 6m @
0.57 g/t Au. Due to the large strike and width extents of the
mineralisation at Dako, significant drilling is required to
effectively delineate the mineral resource potential with many
areas and artisanal excavations currently untested.
Previous Exploration Target
modelling by CSA Global (now ERM) calculated an Exploration Target
range of 2.6 - 3.5Mt @ 0.60-1.29 g/t Au for Dako, (see announcement
dated 7 November 2022) based on limited drilling available at the
time. With future drilling this number is expected to increase
significantly.

Djolibadakoun
Djolibadakoun is located to the east
of the Berebogoni - Woyodakoun target and along an eastern
secondary gold bearing structure. Mineralisation has a known strike
extent of 850m (open at both ends) and is approximately 75m wide.
Due to the area being largely covered by laterite, its true extents
are yet to be delineated.
Sampling of the orpaillage workings
has returned the following grab values, 3.47 g/t Au, 0.96 g/t Au
and 0.79 g/t Au, with the best channel intervals from BCH033 6m @
3.39 g/t Au, BCH042 6m @ 1.32 g/t Au and BCH043 6m @ 1.86 g/t Au.
The majority of sampled channels all started and ended in low to
anomalous grades of mineralisation and with sampling locations
restricted due to limited exposure inside the smaller orpaillage
excavations. Best grab samples returned values of 6.99 g/t Au, 3.47
g/t Au and 1.27 g/t Au, with many other encouraging values
confirming the presence of mineralisation to be tested by future
drilling. No drilling has been conducted at the target. The
Djolibadakoun target was modelled by CSA Global (now ERM), which
calculated an Exploration target range of 0.7 - 0.9Mt @ 0.76-1.06
g/t Au (see announcement dated 7 November 2022) and in light of the
recent exploration work, an increase in the range of tonnes is
expected following a future phase of drilling.

Fode 1
The Fode 1 exploration target is
located on the footwall of the SMSZ (Bokoro structure) directly
opposite and 700m west of the Zone B north deposit. The target area
is defined by existing artisanal miners' workings, which extend for
more than 1km in strike and up to 100m wide in places over 2
parallel zones of mineralisation. Preliminary reconnaissance style
shallow drilling has been carried out, which returned the following
results, SC0651 11m @ 0.94 g/t Au and 10m @ 0.60 g/t Au (2 zones
intersected with a 30m wide shear zone) and SC0652 7m @ 1.32 g/t Au
(this same hole intersected 3-4 zones of mineralisation over a 35m
wide structure, with the hole ending in mineralisation at a depth
of 138m). Recent rock chip samples and channel sample results
returned the following, 5.7 g/t Au, 4.6 g/t Au and 3.8 g/t Au from
rock chips (taken from within highly weathered cross cutting quartz
veins within a sandstone host rock). Due to safety reasons and
restricted accessibility, few channel samples have been
taken.
Fode 1 target was modelled by CSA
Global (now ERM), which calculated an Exploration Target range of
0.9 - 1.2Mt @ 0.77-1.99 g/t Au (as reported (see announcement dated
7 November 2022). Due to its proximity to planned haulage
infrastructure and potential for higher grades at Fode 1, it
remains a priority target for the Company and is undergoing further
assessment of its mineral resource potential and future drill
planning.

Additional Targets
Outside of these 7 targets another
13 targets exist on which the Company's geologists are
systematically collecting data and advancing towards reconnaissance
drill evaluation status. Most of these early greenfield targets
have not been drilled nor contribute towards the Company's
Exploration Target modelling as carried out by CSA Global (now ERM)
in 2022. Some of these targets have been returning high grab and
channel samples values; this includesTRA07 where 56.1g/t Au was
sampled.

target
The 20+ greenfield exploration
targets also do not include the brownfield exploration mineral
resource potential at the 5 established deposits (Zone A, Zone B,
Zone B North, Zone C and Selin) along the SMSZ and Selin shear
zones. The 2022 Exploration Target modelling by CSA Global (now
ERM) calculated an additional total of 7-9.6Mt @ 0.58-1.13 g/t Au
from 150 shallow RC drill holes surrounding these deposits.
Extensive artisanal miner tails material and excavations have
limited the drill rig accessibility in the past, which has
disrupted exploration of these brownfield targets and their mineral
resource definition over the highly prospective 6km strike of the
SMSZ from Zones A and C in the south to Dakounkoro and Dakounkoura
in the north. As part of the Company's wider exploration strategy,
plans are in place to prioritise the brownfield exploration in
conjunction with the greenfield exploration as it looks to grow the
mineral resource base for the Project and in turn increase the
mineable reserves and mine life of the future operation.
Further exploration updates will be
provided as new results come to hand.

Notes
Cora is a West African gold
developer with de-risked project areas within two known gold belts
in Mali and Senegal. Led by a team with a proven track-record in
making multi-million-ounce gold discoveries that have been
developed into operating mines, its primary focus is on developing
the Sanankoro Gold Project in the Yanfolila Gold Belt, south Mali,
into an open pit oxide mine. The November 2022 Definitive
Feasibility Study, based on a gold price of US$1,750/oz, had a
Maiden Probable Oxide Reserve of 422koz @ 1.3 g/t Au, and strong
economic fundamentals, including 52% IRR, US$234 million Free Cash
Flow over life of mine and all-in sustaining costs of US$997/oz.
Alongside this, the Company continues to seek value opportunities
across its portfolio and has identified large scale gold
mineralisation potential at the Madina Foulbé exploration permit
within the Kenieba Project Area in east Senegal.
