Gold District
Vancouver, British Columbia--(Newsfile Corp. - February 10, 2022) -
Cabral Gold Inc.
(TSXV: CBR)
(OTC PINK: CBGZF)
("Cabral" or the
"
Company
") is pleased to provide assay results from three
diamond-drill holes testing the Central gold deposit within the Cuiú Cuiú gold
district in northern Brazil.
Highlights are as follows:
DDH250, intersected 111.3m of nearly continuous mineralization from surface at the Central
deposit, including
23.8m @ 5.5 g/t gold
from 87.5m, in hard unoxidized, brecciated and altered basement
intrusive rocks including
0.7m @ 98.4 g/t gold
from 87.5m, and
1.2m @ 51.0 g/t gold
from
110.1m
84.9m @ 0.7 g/t
gold
from surface within oxidized rocks directly above the unoxidized
mineralization, including
16.7@ 0.5 g/t gold
from surface in the gold-in-oxide blanket, and
68.2m @ 0.8
g/t gold from 16.7m in oxidized and weathered intrusive rocks
DDH255 returned
37.0m @ 1.3 g/t gold
from 42.0m in oxidized and weathered basement rocks,
including
1.6m @ 13.0 g/t gold
, from 44.0m. The hole also intersected 17m @ 0.2 g/t gold from
surface within gold-in-oxide blanket material
DDH258 also intersected
60m @ 0.8 g/t gold
from 121.0m in hard brecciated and altered
basement mineralization. The hole also returned a thin veneer of blanket cover, returning 5.8m @
0.2 g/t gold from surface and 19.0m @ 0.3 g/t gold from 64.0m in oxidized weathered and
mineralized basement rocks.
The hole ended in mineralization grading
0.9 g/t gold
, suggesting
mineralization is open at depth
Alan Carter, Cabral's President and CEO commented, "The results from the diamond drilling at the
Central gold deposit are exceeding our expectations. There is clearly a thick zone of soft, weathered,
mineralized gold-in-oxide material sitting directly above the primary Central gold deposit.
Furthermore, these results confirm that significant zones of high-grade gold mineralization occur
within the underlying, unweathered and hard basement gold deposit. With four drill rigs currently
turning at Cuiú Cuiú, and several new discoveries within the district, notably at PDM and Machichie,
we look forward to a very busy few months and a constant stream of drill results."
Central Diamond-Drill Results
The Central gold deposit is located 2.5km SE of the PDM target (Figure 1) within the Cuiú Cuiú gold
district.

Two rigs are currently operating at Central: an RC rig drilling shallow holes to assess the extent of the
recently identified near-surface gold-in-oxide blanket (see press release dated January 27, 2022) and a
diamond rig to better define the high-grade, highly altered, brecciated and sheared zones within the
primary basement deposit as well as to test the near surface gold-in-oxide blanket.
A total of eight diamond-drill holes were completed at Central in late 2021 and drilling is ongoing. Assay
results are reported herein from three holes; DDH250, DDH255 and DDH258. These were completed in
the central and southern portions of the Central deposit (Figure 2, Table 1). Assay results from the initial
three holes were previously reported (see press release dated January 27, 2022). The principal
objective of this drilling program is to identify and define the individual higher-grade zones within the
Central gold deposit, whilst exploring for additional high-grade mineralization in parts of the current
resource with a low historic drill density.

DDH250
DDH250 was drilled on section N20920 (Figures 2 and 3, Table 1) approximately 45m SW of historic
hole CC03 which cut
134.5m @ 1.1 g/t gold
.
DDH250 intersected
84.9m @ 0.7 g/t
gold
within oxidized material from surface. This intercept includes
an upper blanket sequence of unconsolidated soil, muds and sands, that returned
16.7m @ 0.5 g/t gold
from surface. This is directly underlain by weathered oxidized mineralized intrusive rocks that returned
68.2m @ 0.8 g/t gold
to a depth of 84.9m.
The aforementioned weathered mineralization in DDH250 directly overlies fresh primary gold
mineralization within highly altered and brecciated intrusive rocks. The hole intersected
23.8m @ 5.5 g/t
gold
from 87.5m, including
0.7m @ 98.4 g/t gold
from 87.5m, and
1.2m @ 51.0 g/t gold
from 110.1m.
This section of very high-grade mineralization was not intersected in CC03, which cut the same
subvertical mineralized zone approximately 70m below DDH250.

shows historic drill hole CC-03 which intersected 134.5m @ 1.1 g/t gold

DDH255
DDH255 was drilled on section N20995 (Figures 2 and 4, Table 1). It encountered gold mineralization in
the blanket, weathered oxidized basement and minor mineralization within the footwall in fresh
unweathered basement rocks. The hole was primarily designed to test the weathered basement
mineralization extending nearer to surface.
This hole was drilled on the same section as drill hole CC13, which returned
48.1m @ 4.5 g/t
from
36.7m, including
16.8m @ 10.8 g/t gold
from 50.2m. Drill hole CC13 also returned several deeper
higher-grade intervals and numerous narrower mineralized alteration zones in the footwall including
2.2m
@ 7.6 g/t
from 104.8m,
2.0m @ 40.8 g/t gold
from 165.2m and
0.8m @ 5.8 g/t
from 176.7m.
DDH255 intersected 17m @ 0.2 g/t gold from surface in gold-in-oxide blanket material.
DDH255 also returned
37.0m @ 1.3 g/t gold
from 42.0m, including
1.6m @ 13.0 g/t gold
from 44m,
which is interpreted to be the downdip extension of one of the high-grade zones in CC13. This intercept
in DDH255 occurs in highly weathered oxidized basement rocks. DDH255 was collared too far NE to
test for the other deep high-grade zones intersected in CC13.
Figure 4: Section N20995 through the Central deposit showing the location of DDH255. Note upper
section of 17m @ 0.2 g/t gold in colluvial gold-in-oxide blanket. The underlying intercept of 37m @
1.3 g/t gold is weathered oxidized primary deposit in brecciated and altered intrusive rocks

DDH258
DDH258 was drilled on section N20970 (Figures 2 and 5, Table 1), the same section as DDH251 and
DDH252 (see press release dated January 27, 2022). It encountered weak gold mineralization within
blanket and weathered bedrock, but cut strong mineralization within the main zone in fresh underlying
primary altered and brecciated intrusive basement rocks.
As the hole was collared off the main mineralized trend and drilled towards the NE to primarily test
basement mineralization, the oxide mineralization was just a thin veneer as expected, returning
5.8m @
0.2 g/t gold
from surface. Similarly, the weathered mineralized basement intercept is above the low-
grade alteration halo southwest of the main northeast-trending basement gold zone, and was largely
barren. It returned just
19.0m @ 0.3 g/t gold
from 64.0m.
The primary basement gold zone in DDH258, however, showed continuous mineralization over a broad
width in fresh (unweathered) highly brecciated and highly altered intrusive rocks, returning
60m @ 0.8 g/t
gold
from 121.0m.
This intercept is 50m below notable intercepts previously announced from DDH251,
which occurred within the weathered oxidized mineralized basement. The results from DDH251 included
55.5m @ 1.1 g/t gold
and
15.5m @ 1.7 g/t gold
.
DDH258 also intersected a narrow zone of mineralization grading
0.9 g/t gold
from 201.0m to the end
of the hole (202.7m), suggesting that the mineralized zone could still be open at depth to the northeast.
Figure 5: Section N20970 through the Central deposit showing the location of DDH258. Note upper
sections of 5.8m @ 0.2 g/t gold in colluvial gold-in-oxide blanket and 19.0m @ 0.3 g/t gold in
weathered basement rocks. Underlying intercept of 60m @ 0.8 g/t gold is in unweathered intrusive
rocks comprising primary basement deposit

Drilling and Trenching Update
Results are currently pending on an additional four diamond-drill holes at Central and drilling is
continuing.
In addition to the extensive diamond-drilling program that is in progress, assay results are also pending
on 11 RC drill holes at Central, and RC drilling aimed at further defining the extent of the gold-in-oxide
blanket material is also in progress.
