Central
Vancouver, British Columbia--(Newsfile Corp. - April 13, 2022) -
Cabral Gold Inc.
(TSXV: CBR) (OTC
Pink: CBGZF)
("Cabral" or the
"
Company
") is pleased to provide assay results from four diamond-
drill holes testing the primary Central gold deposit within the Cuiú Cuiú gold
district, northern Brazil.
Highlights are as follows:
DDH266
tested the main Central mineralized zone and returned a high-grade intercept, as well as
multiple lower-grade intervals, including:
1.7m @ 14.9 g/t gold from 74.4m.
This high-grade intercept occurs in the southern part of the
deposit, within fresh (unweathered), brecciated and altered basement intrusive rocks.
4.4m @ 1.0 g/t gold
from 89.3m,
0.5m @ 5.8 g/t gold
from 108.2m,
2.1m @ 1.2 g/t gold
from 117.2m, and
11.1m @ 1.5 g/t gold
from 122.8m. All of these intercepts also occur
within fresh, strongly brecciated and highly altered basement intrusive rocks.
12.7m @ 0.5 g/t gold
from 15.0m and
7m @ 1.0 g/t gold
from 35.7m. Both intercepts occur
in highly weathered and oxidized mineralized basement closer to surface.
12m @ 0.7 g/t
gold
was also encountered from surface in the overlying gold-in-oxide blanket.
DDH265,
was drilled to test the northeastern limit of the mineralized zone at Central. It returned
18.3m @ 0.7 g/t gold
from surface in the overlying gold-in-oxide blanket.
DDH248
was designed to test the near-surface extension of the weathered Central basement
zone. It intersected
27m @ 0.6 g/t gold
from surface, including
7.5m @ 0.3 g/t gold
in the
overlying gold-in-oxide blanket, and
19.5m @ 0.8
g/t gold
within mineralized basement saprolite.
The results from all four holes further support previous drilling, defining a significant thick zone of gold-in-
oxide mineralization sitting above the primary unweathered gold deposit at Central. It comprises a
combination of overlying sub-horizontal, gold-in-oxide blanket, as well as a thick zone of highly
weathered saprolite material representing the highly weathered subvertical primary gold mineralization.
This oxide (saprolite) mineralization extends from the base of the blanket (near surface) to depths
greater than 70m.
Alan Carter, Cabral's President and CEO commented, "The latest drill results from Central lend
further support to recent evidence from drilling that a high-grade zone of mineralization exists within
the core of the primary basement Central gold deposit, just as at the nearby MG gold deposit.
Furthermore, all of the holes reported here cut significant intercepts of soft weathered gold-in-oxide
mineralization, supporting previous drilling that a third significant zone of gold-in-oxide mineralization
sits above the primary un-weathered basement deposit at Central. We look forward to the results of the
ongoing drill program at Central as well as the results from the four other drill rigs which are currently
active at the nearby MG, Machichie, PDM and Indio targets."
Central Diamond-Drill Results
The Central gold deposit is located 5km NW of the MG gold deposit and 2.5km SE of the PDM target
within the Cuiú Cuiú gold district (Figure 1).

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) as
well as a diamond rig to both better define the high-grade, highly altered, brecciated and sheared zones
within the primary basement deposit and to define the near surface gold-in-oxide mineralization.
Assay results are reported herein from four diamond-drill holes recently completed at Central: DDH248,
DDH249, DDH265 and DDH266. These were completed on section N20845, located in the
southeastern part of the Central gold deposit (Figure 2, Table 1).

Assay results from the initial six holes of this program were previously reported and included
23.8m @
5.5 g/t gold
in DDH250 (see press releases dated January 27, 2022 and 10
February 10, 2022). The
principal objective of the current 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, and testing for oxidized mineralization closer to
surface where historic drilling was extremely sparse.

Section N20845
All of the holes reported here were drilled on section N20845 which is located in the southern portion of
the primary Central gold deposit (Figures 2 and 3, Table 1), approximately 75m south of DDH250, which
recently returned
23.8m @ 5.5 g/t gold.
Results from DDH247, drilled on Section N20845, were
previously reported (see press releases dated January 27, 2022), and are shown on Figure 3.
Prior to the current drill program there was only one historic hole within the oxide on this section (Figure
3). That hole (CC_12) was drilled southeast to northwest, orthogonal to the section. Less than 20m of the
hole that occurs within the 25m window of Section N20845. Furthermore, the first 13.3m of the gold-in-
oxide blanket extending from surface in CC_12, was not even sampled for gold (Figure 3).
Only one historic hole (CC_104) was drilled across the entire strike Central main zone on this section. All
other holes were drilled orthogonal to the section, parallel to the mineralized zone. The pierce points are
shown on Figure 3 where they cross the 25m window of Section N20845.
With the exception of
orthogonal hole CC_12, the shallowest historic intercept at the southwestern margin of the zone was
over 100m deep, while the shallowest historic intercept on the northeastern margin of the zone was over
175m deep (Figure 3).
DDH265 and DDH266
DDH265 and DDH266 were designed to define the northeastern and southwestern limits of the Central
mineralized zone on this section, whilst testing for the up-dip extension of basement mineralization in
weathered saprolite closer to surface.
DDH266 was drilled towards the southwest across the primary basement gold deposit (Figure 3) It
intersected three significant zones of mineralization in the overlying weathered gold-in-oxide material.
The uppermost, was
12.0m @ 0.7 g/t gold
from surface within the overlying gold-in-oxide blanket.
Beneath that, the hole cut
12.7m @ 0.5 g/t
gold
from 15.0m and
7.0m @ 1.0 g/t
gold
from 35.7m. Both
of these intercepts are in saprolite, representing highly weathered vertically dipping basement
mineralization.
DDH266 then passed into
hard unoxidized, brecciated and altered basement intrusive rocks and cut a
number of mineralized intercepts (Figure 3) including
1.7m @ 14.9 g/t gold
from 74.4m,
4.4m @ 1.0 g/t
gold
from 89.3m,
0.5m @ 5.8 g/t
gold
from 108.2m,
2.1m @ 1.2 g/t
gold
from 117.2m depth, and
11.1m @ 1.5 g/t
gold
from 122.8m.
DDH265 was drilled from the same platform as DDH266, but in the opposite direction towards the
northeast away from the primary basement gold deposit. It was designed to define the northeastern limit
of the mineralized system. It did not encounter any significant mineralization within fresh basement rocks.
However, DDH266 did intersect
18.3m @ 0.7 g/t gold
from surface in the overlying gold-in-oxide
blanket. This intercept lies northeast of interpreted northeastern limit of basement mineralization. It
indicates that the flat-lying unconformable blanket remains open to the northeast.

locations of diamond drill holes DDH247, DDH248, DDH265 and DDH266 and recent drill results. A
subvertical, narrow post-mineralization porphyritic rhyolite dyke cuts across this section, and is shown
in orange.

DDH248 and DDH249
DDH248 and DDH249 were shallow holes drilled in the middle part of section N20845 from the same
platform (Figures 2 and 3). These holes were designed to test for both the flat-lying gold-in-oxide blanket
mineralization at surface, and the up-dip extension of subvertical-dipping, highly weathered and oxidized,
mineralized basement saprolite.
DDH248 intersected
27m @ 0.6 g/t gold
from surface in oxidized and weathered basement rocks. This
broader intercept comprised
7.5m @ 0.3 g/t gold
in the flat-lying gold-in-oxide blanket from surface, and
19.5m @ 0.8 g/t gold
from 7.5m within the underlying subvertical-dipping, highly weathered and
oxidized, mineralized basement saprolite.
Similarly, DH249 returned 9.4m @ 0.2 g/t gold from surface in the flat-lying gold-in-oxide blanket. Further
downhole, it also encountered 5m @ 0.5 g/t gold from 13m, and 6m @ 0.4 g/t gold. The latter two
intercepts are in saprolite and represent the highly weathered and oxidized up-dip extension of
subvertical-dipping mineralized basement.
Interpretation and Observations
Drilling on Section N20845 was successful in further defining the extent of the flat-lying gold-in-oxide
blanket mineralization. All four holes support previous drilling in DDH247 (11.0m @0.7 g/t gold from
surface), that a third significant zone of gold-in-oxide mineralization blanket mineralization sits
unconformably above primary Central gold mineralization. The interpreted long-axis of this blanket zone
trends to the NW parallel to the trend of basement mineralization (Figure 2). On this section, it can be
traced across strike NE-SW more than 100m
. It is still open to both the northeast and southwest
(Figure 3). This material is very soft and comprises mainly unconsolidated muds and sands. It should be
free digging material. As at the MG deposit, this material could be amenable to low-cost, low-capital
heap-leach processing.
Drilling on Section N20845 was also successful in establishing that vertical-dipping Central gold
mineralization continues through the weathered profile to the base of the blanket. Three of the holes
within this release (DDH248, DDH249, and DDH266) encountered weathered and oxidized mineralized
basement material, as did DDH247 (Figure 3). Within this profile, the mineralized basement brecciated
and altered intrusive rock have been completely weathered and oxidized to saprolite, while maintaining
much of the original igneous and breccia textures.
Whilst the entire weathered basement profile is completely oxidized, the upper part of the saprolite is
very soft and could be free digging. Rock competence appears to increase with depth as the intensity of
weathering diminishes. Regardless,
this entire oxidized weathered primary profile extends to
depths that locally exceed 70m and is approximately 80m in width
on this section. As at MG, this
material could also be amenable to low-cost, low-capital heap-leach processing.
DDH266 was the only new hole on this section into the fresh basement mineralization.
It reaffirms the up-
dip extension of basement mineralization encountered in historic hole CC_04, whilst also cutting a new
high-grade zone in the middle of the deposit (
1.7m @ 14.98 g/t gold
).
Drilling and Trenching Update
Results are pending on eight diamond-drill holes at MG and drilling is continuing.
Results are pending on seven diamond-drill holes at Central and drilling is continuing.
Results are pending on 36 RC holes drilled north of Central which are aimed at further defining the extent
of the near surface gold-in-oxide blanket material. The RC rig has now moved to complete infill drilling at
the PDM gold-in-oxide blanket with a particular focus on further defining the higher grade core to the
blanket.
At the recently discovered mineralized zone in basement granitic rocks at the PDM target located 2.5km
NW of Central (see press release dated January 12, 2022), diamond-drilling also has been temporarily
suspended as assay results have become too backlogged. Results on twelve diamond-drill holes are
currently pending, and need to be interpreted for additional drill hole planning.
Meanwhile, the diamond drill has been redeployed from PDM to Machichie, where an infill and step-out
drilling program has just begun and trenching is still in progress.
Results are currently pending on the first two diamond-drill holes drilled in 2022 at the Indio target.
Drilling is ongoing.
