Defines a High-grade Corridor at Central Gold
Deposit, Cuiú Cuiú Gold District
Vancouver, British Columbia--(Newsfile Corp. - May 3, 2022) -
Cabral Gold Inc. (TSXV: CBR) (OTC
Pink: CBGZF) ("Cabral" or the "Company")
is pleased to provide assay results from three diamond-
drill holes on two sections in the southern part of the primary Central gold deposit within the Cuiú Cuiú
Gold District, northern Brazil.
Highlights are as follows:
DDH268
tested the emerging high-grade zone at Central on section N20870 and returned the
following mineralized intervals:
9.6m @ 16.4 g/t gold
from 164.3m
including 1.2m @ 112.0 g/t gold
from 166.9m and
2.1m
@ 11.5 g/t gold
from 170.2m. This high-grade intercept occurs within fresh (unweathered),
highly brecciated and altered basement intrusive rocks
17.5m @ 0.5 g/t gold
from 76.4m, and
30.4m @ 1.1 g/t gold
from 130.0m. These intercepts
also occur within fresh, strongly brecciated and highly altered basement intrusive rocks
DDH267
was drilled on section N20845 to test both the high-grade zone and the down-dip
continuity of the deposit at Central. It returned the following mineralized intervals:
12.8m @ 1.0 g/t gold
from 82.6m including
0.9m @ 8.1 g/t gold
from 94.5m
17.5m @ 1.9 g/t gold
from 149.5m, including
3.2m @ 5.3 g/t gold
from 156.0m, and
1.3m @
5.9 g/t gold
from 162.5m
5.5m @ 2.1 g/t gold
from 189.0m including
1.0m @ 6.6 g/t gold
from 191.0m
DDH281
was also drilled on section N20870 to define the northeastern limit of the mineralized
zone at Central. It returned
11.3m @ 0.7 g/t gold
from surface in the overlying gold-in-oxide
blanket. The blanket remains open to the northeast, and to the southwest on this section
Drilling suggests there is a distinct northwest-trending, steeply dipping, high-grade corridor that
contains multiple individual high-grade zones. The corridor follows the southwestern margin of the
Central deposit in this area. It has now been traced for over 100m along strike, appears to be over
25m wide, and remains open at depth below 350m
Alan Carter, Cabral's President and CEO commented, "These latest very high-grade drill results from
Central lend further support to recent evidence from drilling that a high-grade corridor of
mineralization exists within the core of the primary basement Central gold deposit. This high-grade
zone has now been traced along strike for at least 100m and remains open to the northwest and
southeast. Furthermore, it has been encountered in one of the deepest historic holes on the project, at
350m below surface. The high-grade zone is open down-dip on all of the sections in the corridor.
We
look forward to the results of the ongoing drill program at Central, as well as further 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 northwest of the MG gold deposit and 2.5km southeast of the
PDM target within the Cuiú Cuiú gold district (Figure 1).

Diamond drilling at Central has been designed to: 1) better establish continuity and define high-grade,
highly altered, brecciated and sheared zones within the primary basement deposit, 2) explore for
additional high-grade mineralization in parts of the current resource with a low historic drill density, and
3) improve definition of the near-surface gold-in-oxide mineralization, a portion of the deposit that was
historically largely undrilled. The near-surface oxide mineralization could be very important should heap-
leach processing prove viable.
Assay results are reported herein from three diamond-drill holes recently completed on two adjacent
sections located in the southern portion of the Central deposit (Figures 2, 3, and 4). DDH268 and
DDH281 were completed on section N20870.
DDH267 was drilled on the next section to the southeast,
N20845.

Section N20870
DDH268 was drilled on section N20870 (Figures 2 and 3, Table 1) approximately 50m south-east of
DDH250, which was drilled on section N20920 and recently returned
23.8m @ 5.5 g/t gold
(see press
release dated February 10, 2022).
DDH268 was drilled from northeast to the southwest across the entire main Central mineralized zone. It
encountered two high-grade intervals (Figure 3, Table 1). The first is
9.6m @ 16.4 g/t gold
from 164.4m,
including
1.2m @ 112.0 g/t gold
from 167.0m. The second is slightly further downhole,
2.1m @ 11.5 g/t
gold
from 170.2m.
DDH268 also intersected a number of lower grade intervals, including
17.5m @ 0.5
g/t gold
from 76.4m,
7m @ 0.3 g/t gold
from 114.9m and
30.4m @ 1.1 g/t gold
from 130.0m.
All of the
above intercepts are hosted by fresh, strongly brecciated and highly altered basement intrusive rocks.
DDH281 was drilled on section N20870. It was designed to test define the northeastern limit of the
mineralized zone at Central near surface. It did not encounter primary mineralization, but did return
11.3m @ 0.7 g/t gold
from surface in the unconformably overlying gold-in-oxide blanket, which remains
open to the northeast of DDH268 (Figures 2 and 3 and Table 1).
The mineralized zone on section N20870 remains open at depth.

Section N20845
DDH267 was drilled on section N20845 (Figures 2 and 4). Results from other holes on section N20845
were recently reported, including DDH265, DDH266, DDH248 and DDH249 (see press release dated
13
th
April 2022). Those were highlighted by DDH266, which returned
1.7m @ 14.9 g/t gold
.
DDH267 cut multiple mineralized intervals (Figures 2 and 4 and Table 1), including:
12.8m @ 1.0 g/t
gold
from 82.7m, including
0.9m @ 8.1 g/t gold
from 94.5m;
17.5m @ 1.9 g/t gold
from 149.5m,
including
3.2m @ 5.3 g/t gold
from 156.0m; and
1.3m @ 5.9 g/t gold
from 162.5m
.
The hole also
intersected
5.5m @ 2.1 g/t gold
from 189.0m, including
1.0m @ 6.6 g/t gold
from 191.0m.
Several lower grade sections were also returned from DDH267 including
7.0m @ 0.3 g/t gold
from
63.0m,
12.8m @ 1.0 g/t gold
from 82.7m and
10.0m @ 0.4 g/t gold
from 126.0m.
All of these intervals
occur in fresh (unweathered), brecciated and altered basement intrusive rocks.
Only one historic hole, CC_04 had been drilled across this section.
It intersected mineralization at a
vertical depth of 185m. The newer mineralized intercepts demonstrate the continuity of the mineralized
zone intersected in CC_04.
Historic hole CC_16, was drilled orthogonal to this section, and thus far is the deepest intersection on
the section, at a vertical depth of 290m.
The mineralized zone remains open at depth on section N20845.

Interpretation and Observations
Establishing a High-Grade Corridor in the Southern Central Gold Deposit
Drilling continues to support the broad, extensive mineralized zone that defines most of the Central
deposit. However, within that lower-grade larger deposit, high-grade mineralization has now been
encountered on sections N20920, N20870, N20845, and N20825. The location of this high-grade
mineralization further supports the company's thesis that there is a steeply dipping, northwest-trending
high-grade corridor in this southern portion of the Central deposit. It occurs along the southwestern
margin of the deposit, and encompasses a number of parallel high-grade structures. To date, the
northwest-trending corridor has now been traced more than 100m along strike. It appears to be over
25m wide and extends to over 350m deep.
Inside that corridor, there are numerous high-grade intercepts in both historic and recent drill holes.
These occur both up-dip and downdip of the
9.6m @ 16.4 g/t gold
intercept encountered by DDH268
on section N20870 (Figure 3), as well as the
5.5m @ 2.1 g/t
and
3.2m @ 5.3 g/t gold
intercepts in
DDH267 on section N20845 (Figure 4). The intercept in DDH268 is almost certainly the same high-
grade corridor that was intercepted further to the northwest in hole DDH250 (section N20920). It returned
23.8m @ 5.5 g/t gold
, including
0.7m @ 98.4 g/t gold
, and
1.2m @ 51.0 g/t gold
(see press release
dated February 10, 2022). A historic hole (CC_45), drilled from the southwest to the north, intersected
8.0m @ 5.7 g/t gold
from 384.5m, including
3.0m @ 12.4 g/t gold
from 385.6m.
That intercept lies on
section N20825, within the corridor, and just 20m south of the N20845.
The CC_45 intercept is
approximately 350m below surface.
There were only two holes that had previously been drilled across strike on section N20870 (Figure 3):
CC_15, was a historic hole, and DDH205 was drilled by Cabral during its initial 2019 reconnaissance
Central drill campaign (see press release dated February 5, 2020). CC_15 cut a broad high-grade
interval across the corridor, returning
40.2m @ 2.8 g/t gold
from 182.2m, including:
2.6m @ 7.9 g/t
gold
from 182.2m,
2.0m @ 8.0 g/t gold
from 202.0m, and
5.1m @ 14.1 g/t gold
from 217.3m.
DDH205, also had multiple higher-grade intercepts within the corridor, returning
3.6m @ 6.0 g/t gold
from 140.4m,
0.6m @ 5.1 g/t gold
from 150.0m,
1.7m @ 5.2 g/t gold
from 193.9m,
2.8m @ 5.4 g/t
gold
from 218.6m, and
0.5m @ 12.0 g/t gold
from 244.8m.
Most of the earlier historic holes on these two northeast-trending sectional planes (N20870 and N20845)
were drilled either northwest to southeast, or southeast to northwest. We now know that this is on strike
and parallel to the overall mineralized trend.
On-strike data is very difficult to correlate. CC_16, 32, and
38 were all drilled within the corridor and pierced both sections (Figures 3 and 4). All three of the holes
cut multiple high-grade intercepts in the corridor. However, only the portions of these holes that occur
within the 25m windows of section N20870 and N20845 are shown on Figures 3 and 4. For example,
CC_32 was drilled from northwest to southeast through the sections.
It intersected four separate high-
grade zones within the northwest-trending corridor.
The first high-grade zone was
23.8m @ 8.3 g/t gold
from 88.0m, including
7.8m @ 22.4 g/t gold
from
88.0m. The second was
28.4m @ 5.4 g/t gold
from 245.6m, including
4.7m @ 23.7 g/t gold
from
246.6m, and
1.0m @ 9.1 g/t gold from 261.2
. The third and fourth were
1.0m @ 8.6 g/t gold
from
293.7 and
1.4 m @ 11.0 g/t gold
from 307.3m, respectively. CC_32 ended in mineralization at 330.7m.
However, only the first intercept (23.8m @ 8.3 g/t gold) lies within the sectional window for N20870 that
shown on Figure 3. Similarly, only the second interval (
4.7m @ 23.7 g/t gold
) is shown on section
N20845 on Figure 4.
The deeper intercepts cut by CC_32 lie to the southeast of that northeast-oriented
sectional plane.
Further drilling will be required to better define and expand the high-grade corridor. It remains
open on strike and downdip.
Drilling and Trenching Update
Results are pending on four diamond-drill holes at MG and drilling is continuing.
Results are pending on six diamond-drill holes at Central and drilling is continuing.
Results are also pending on 36 RC holes drilled north of Central. These holes were designed to define
the extent of near surface gold-in-oxide blanket material.
Results for three diamond-drill holes are pending at PDM. These are required for planning additional drill
holes. Results are also pending on six RC holes at PDM. RC drilling has commenced to better define the
gold-in-oxide blanket at PDM and drilling is ongoing.
Results are pending on the first three diamond-drill holes drilled in 2022 at the Indio target and drilling is
continuing.
Results are pending on two follow-up diamond-drill holes at Machichie and drilling is continuing.
