('Cora' or 'the
Company')
Drill results confirm large scale gold
mineralisation potential
at Madina Foulbé in East
Senegal
Cora Gold Limited, the West African focused
gold company, is pleased to announce that it has completed a
reconnaissance Reverse Circulation ('RC') drilling programme at the
Tambor gold anomaly, which is one of four key target areas within
the Company's Madina Foulbé exploration permit within the Kenieba
Project Area ('the Project') in east Senegal. The permit is in
close proximity to several Tier 1 gold deposits located within the
Mako Geological Belt of the Kédougou-Kéniéba Inlier ('KKI') (see
Figure 1).
DRILL
HIGHLIGHTS
· 40
shallow RC holes drilled for 2,018m to test 10 of the most
prospective targets within a large 3km long by 1.6km wide gold soil
anomaly (>20ppb) at Tambor.
· 6
out of 10 targets drilled (28 of the 40 holes) were successful at
intersecting mineralisation over broad widths, with results that
require further follow-up.
·
Best results are as follows:
o 10m @ 4.41g/t
gold ('Au') from 41m in hole MFC0013 at Target 1
o 16m @ 0.97g/t
Au from 38m in hole MFC0014 at Target 1
o 29m @ 0.71g/t
Au from 1m in hole MFC0021 at Target 9
o 19m @ 0.61g/t
Au from 34m in hole MFC0049 at Target 8
· At
Target 1 (where hole MFC0013 intersected 10m @ 4.41g/t
Au), all six holes encountered broad mineralisation, indicating the
presence of a 60m wide zone, which remains open in all directions,
including at depth.
·
Over 50% of holes drilled ended in mineralisation, with an
average hole length of just 50m, which offers encouragement for
future drill programmes.
·
Assays have now been sent for ICP-MS (4 acid) analysis, which
will give multi-element data to better understand this large gold
system and plan a more effective follow-up exploration programme to
target higher grade and broader zones of
mineralisation.
· The
Company will now assess and evaluate the next steps to follow-up on
these discovery holes.
Bert Monro,
Chief Executive Officer of Cora, commented,
"Up until this point Madina Foulbé has been largely
untested, so with six of our ten high priority targets confirming
gold mineralisation, we are pleased with the results received from
what was a first pass reconnaissance programme. We have been able
to identify multiple broad zones with elevated gold and some
economic intercepts, including 10m @ 4.41 g.t Au, with over half
the holes ending in mineralisation from a shallow programme
designed to test a wider area. This gives us good confidence that,
with further exploration, we could define resources in the
future.
"In support
of this, the Project is close to several operating mines and is
serviced by excellent infrastructure within a mining friendly
jurisdiction. We now look forward to receiving the additional
ICP-MS analysis results from which we will then look to plan our
next development steps."

DRILL
PROGRAMME DETAILS
In May 2024 Cora completed a reconnaissance RC
drilling programme at the Tambor gold anomaly, which is one of four
key target areas within the Company's Madina Foulbé's exploration
permit. 40 shallow holes for 2,018m were drilled at 10 prospective
targets within the large 3km long +1km wide Tambor gold soil
anomaly previously identified (see Figure 2). Only one of these
targets has been drill tested as part of a brief RC programme,
which commenced in April 2020. This year's drill programme
was designed to test for in-situ gold mineralisation beneath the
soil and termite anomaly to understand the broader exploration
potential of the gold system that generated the large and
high-grade gold-in-soil anomaly at Tambor (see Figure
3).
Six of the 10 targets drilled were successful
in returning anomalous to economic intercepts. The best of these
targets and their drill results are summarised in the table
below.

The criteria used for reporting the
intercepts were, sample cut-off >0.35g/t Au, minimum interval
width of 3m and maximum internal waste interval of 4m.

Target
1
Never previously drill tested before, six holes
(see Figure 4.) were drilled targeting an area considered to be the
most prospective within the Tambor anomaly. The drill results
supported this, with hole MFC0013 returning 10m @ 4.41g/t Au from
41m, with the hole also intersecting three other separate anomalous
mineralised zones, finishing within mineralisation at 70m depth.
The other two holes (MFC0014 & 0015) drilled approximately 40m
and 80m apart from hole MFC0013, all intersected the same zone of
mineralisation, MFC0014 returning 16m @ 0.97g/t Au (within a
broader interval of 48m @ 0.47g/t Au) and MFC0015 returning 11m @
0.65g/t Au, with both holes also ending in mineralisation.
These three holes indicate that a good and strong geological
control exists over the distribution and concentration of gold
within this area, which makes it a promising target for future
exploration. Interestingly, the three other holes drilled at Target
1 were testing the anomalous / low grade mineralisation encountered
in some very shallow rotary air blast drilling by Toro Gold Limited
pre-2018 (Toro Gold was subsequently acquired by Resolute Mining
Limited). These three shallow holes (drilled to 40m deep and as a
fence with hole MFC0015) all ended in mineralisation and
encountered broad intercepts of low to anomalous mineralisation
with MFC0016 returning 15m @ 0.53g/t Au and MFC0018, 13m @ 0.29g/t
Au, with the last 4m @ 0.58g/t Au. These results suggest the
potential delineation of a 60m wide zone of
mineralisation.
At Target 1, due to the small number of holes
drilled and their shallow depths, the current drilling has
highlighted that in-situ mineralisation does exist beneath the soil
anomaly, a strong geological control is also present along with
economic and high grades over mineable widths. With mineralisation
essentially open in all directions this is a high priority target
for future exploration and potential resource
definition.

Target 2 or
Granite Hill
The target area is dominated by North-South
trending sheeted quartz veins within sheared granite. Nine initial
RC holes (as two fences) were drilled by Cora in 2020, which
intersected broad, low-grade intervals (refer to RNS announcements
released 30 March 2020, 6 May 2020 & 20 July 2020
respectively). The three holes drilled (MFC0010 - 0013) at Target 2
this year were designed to test continuity of these broader zones,
with the holes drilled approximately 40m apart and along strike of
each other. All three holes were successful in intersecting similar
style and widths of mineralisation, confirming the future resource
potential of this target area. Hole MFC0011 was the best hole
intersecting 36m @ 0.4g/t Au from 14m within a broader zone of 70m
@ 0.3g/t Au. Hole MFC0010 intersected 20m @ 0.38g/t Au and MFC0013
ended in mineralisation after intersecting 67m @ 0.22g/t Au.
Previous bottle roll test work carried out on the Target 2
mineralisation in 2020 by Bureau Veritas Labs in Abidjan, resulted
in an average 98.5% gold recovery from 24 samples with an average
gold concentration of 0.57g/t Au. Column leach test work has
not yet been carried out to test the suitability of these Target 2
ores or the other Tambor targets for heap leach
recovery.
Target
5
A purely conceptual target, Target 5 was
drilled to test for mineralisation under a strong (>100pb)
gold-in-soil anomaly. Drilling intersected mineralisation in two of
the three holes. Hole MFC0034 (40m deep) intersected 15m @ 0.4g/t
Au however ended in mineralisation. Hole MFC0033 to the east of
hole MFC0034 was extended to intersect the down dip mineralisation
and intersected a broad anomalous zone of 31m @ 0.29g/t Au with the
hole still in mineralisation when it was stopped at its planned
depth of 90m. Results indicate a mineralised zone greater than
40-50m wide has potentially been intersected that is currently open
to the north and south.
Target
8
Due to being outside the coverage of the
historical soil sampling programme, initially one hole was planned
at Target 8, which is the site of an abandoned artisanal working.
Hole MFC0045 was panned for gold by Company geologists as it was
being drilled, with geologists recognising that it contained a
broad zone of gold mineralisation based on the Visible Gold (VG)
values being recorded. A second hole MFC0049, the last hole of the
programme, was drilled to follow up hole MFC0045, with assay
results showing the MFC0049 hole intersected a zone of 19m @
0.61g/t Au within a broader lower grade zone of 27m @ 0.49g/t Au
from 33m. Mineralisation at Target 8 is open to the north and
south, with drilling results indicating that grades and widths are
open and improve to the north. This reflects results from grab
samples taken from mineralised veins at the northern end of the
artisanal working that are in close proximity to some deeper
artisanal mining shafts, where the highest grade from the
mineralised veins returned 16.2g/t Au. This area was not
tested as part of this drill programme.
Target
9
Two holes were designed to test low grade grab
sample results taken from within the target area, which is located
in the far north/west of the Tambor anomaly area. This area
wasn't covered by the historical soil sampling grid and the holes
were purely planned as per the programme's objective of being a
reconnaissance drill programme. Hole MFC0021 intersected 29m
@ 0.71g/t Au from surface. A second hole was drilled some 40m away
(not along strike) testing a different zone and intersected three
separate zones of anomalous mineralisation, with the hole ending in
mineralisation of 8m @ 0.24g/t Au.
Targets 3 and
10 (East)
These two large conceptual targets were tested
to determine the source of the highest and largest gold
concentration of the Tambor gold-in-soil anomaly. Due to the
limited nature of the drill programme, three lines of drill holes
were drilled over a restricted area within the two target
areas. The best result from Target 3 (West) was 13m @ 0.2g/t
Au from hole MFC0025, which ended in mineralisation, as did hole
MFC0022 (18m @ 0.11g/t Au), drilled in the same fence line. These
two holes indicate that mineralised zones or structures do exist
under the soil anomaly and further work is required to understand
the resource potential that these broad zones may contain.
Target 3 (East) resulted in four out of the five holes ending in
mineralisation at their planned depths of 40m. Only anomalous
mineralisation was intersected but the results highlight the
frequency and location of mineralised structures that can be mapped
and 3D modelled as part of the Company's interpretation of the
Tambor anomaly.
Target 10 (East), which was located on a
geographical high plateau for the area was also a conceptual target
with no artisanal mining in the area and is located outside of the
main historical soil anomaly / sample grid. A drill fence of five
shallow holes (approximately, 40m apart) was drilled to test for
the possible extension to the soil anomaly from Target 3 (West)
area, 300m to the south. Hole MFC0031 intersected a broad anomalous
gold zone of 30m @ 0.23g/t Au (including 3m @ 0.96g/t) with the
hole ending in mineralisation. While these intercepts at Target 3
and 10 (East) are anomalous in nature, they are broad (representing
the geological control) and gold bearing, which at this early
reconnaissance stage enhances the Company's confidence in the
resource potential at Tambor.
Target 4, 6, 7
& 10 (West)
Drill testing at these four conceptual targets
was unsuccessful at intersecting the source of their respective
gold-in-soil and termite anomalies. Further work will be planned in
the future once all the drill data has been received and a
compilation of the data sets has been completed to assess these
areas, as the fundamentals for targeting these areas remains valid
and further testing will be required.
All samples from the drill programme were
analysed by 50-gram fire assay at ALS Ouagadougou, with all samples
sent off for ICP-MS (4 acid) analysis at ALS Johannesburg, which
will give multi-element data in conjunction with gold assays to
better understand the lithologies present and increase the
Company's knowledge of this large gold system, allowing for a more
effective exploration programme to be planned in the future
to target higher grade or broader zones of mineralisation.
Madina Foulbé Project
Background
The Madina Foulbé permit in eastern Senegal is
approximately 27km directly west of the Sadiola Gold Mine and close
to several other Tier 1 deposits (Loulo, Gounkoto, Fekola) in the
gold belt known as the Kédougou-Kéniéba Inlier ('KKI'). Notably,
two exploration companies within the KKI have recently been
acquired, including Chesser Resources Limited purchased by Fortuna
Silver Mines Inc. in May 2023 for US$60m, with a resource of 860koz
@ 1.77 g/t Au; and Oklo Resources Limited purchased by B2Gold Corp.
in May 2022 for US$66m, with a resource of 668koz @ 1.83 g/t Au.
Madina Foulbé is relatively under explored with only regional work
programmes having been undertaken, which has identified four key
target areas, with Tambor considered the most prospective at this
point in time.
At Tambor, weathering of the host rocks is
weakly developed with the fresh rock commonly found within a few
tens of metres from surface; with little to no laterite formation,
the gold-in-soil anomaly is considered indicative of the underlying
gold mineralisation within the host rocks. Regional geophysical
data sets show a large circular feature coinciding with the Tambor
gold-in-soil anomaly, which in addition to the regional (+200km in
length) scale north-south trending fault system cutting directly
through the centre of the gold-in-soils anomaly, supports the
geological prospectivity of Tambor.
Tambor is only one of four key targets within
the Madina Foulbé exploration area, with the other three being
Tombolo South- Dalaoule, Madina and Diombalou (refer to
announcement on 29 May 2024 for further details). All three
targets are at an early stage of exploration with soil sample
coverage, field mapping and grab sampling completed to date. Early
results confirm widespread gold mineralisation, with further
exploration required to understand their resource potential.
The Tombolo South-Dalaoule target is considered the most
prospective of the three remaining target areas, as it is located
directly along strike to the south of Tambor, approximately 10km
away and is cut by the same regional N-S trending regional
fault. Earlier field work by the Company's geologist showed
that this area and the source of the gold mineralisation could be
related to a large Iron Oxide Copper Gold ('IOCG') style deposit,
due to the presence of anomalous iron, copper and gold in the
soils, and widespread alteration and veining associated with IOCG
deposits. Further detailed field work and drilling is required to
assess its potential.
