Cabral Gold Trenches 20m @ 3.6 g/t Gold on
Surface at the Machichie Main Gold Deposit,
Cuiú Cuiú Gold District, Brazil
Vancouver, British Columbia--(Newsfile Corp. - March 13, 2025) -
Cabral Gold Inc. (TSXV: CBR)
(OTC Pink: CBGZF)
("
Cabral
"
or the
"
Company
") is pleased to announce assay results from 2
surface trenches and 8 reverse circulation ("RC") drill holes at the Machichie Main gold deposit within
the Cuiú Cuiú Gold District, Brazil.
Highlights
Surface trench CT051 at the Machichie Main gold deposit at Cuiú Cuiú returned
20m @ 3.6 g/t
gold
including
4m @ 15.7 g/t gold
in gold-in-oxide material at surface. The mineralized interval
within the trench is open to the north and south. These results confirm the presence of significant
higher-grade mineralization within the near surface gold-in-oxide material at the Machichie Main
deposit
Surface trench CT052, developed 150m west of trench CT051 also returned
7m @ 0.8 g/t gold
.
The mineralized interval is again open to the north and south
RC drill results from Machichie Main include;
4m @ 3.9 g/t gold
from 36m depth including
1m @ 10.6 g/t gold
in RC497
4m @ 3.1 g/t gold
from 41m depth including
1m @ 10.6 g/t gold
in RC496
7m @ 1.5 g/t gold
from 64m depth in RC494
7m @ 1.2 g/t gold
from 78m depth in RC495
1m @ 9.9 g/t gold
from 26m depth and
1m @ 7.3 g/t gold
from 37m depth in RC503
All of these intercepts were in fresh rock intrusive material below the near surface gold-in-
oxide material
Results thus far from the trenches and initial drill holes confirm continuity and grade of the
Machichie mineralization along strike and at depth
Samples from the trenches are in the process of metallurgical testing to characterize the Machichie
oxide zone
Alan Carter, Cabral's President and CEO commented, "The current drilling and trenching program at
Machichie Main is aimed primarily at upgrading the Inferred resource base within the near-surface
gold-in-oxide zone to Indicated resources. These results confirm the presence of significant grades,
both within the near-surface gold in-oxide material which comprises mineralized blanket sediments
and saprolite (weathered bedrock), as well as the underlying fresh primary intrusive material at
Machichie Main. The trench results in particular are significant because they confirm the presence of
excellent grades within gold-in-oxide material at surface. This bodes very well for our efforts to
upgrade the Inferred resources at Machichie Main as we work towards updating the results from the
PFS study on an initial heap leach starter operation previously released in October 2024."
Machichie Main Trench and Drill Results
The Machichie Main zone is an E-W trending zone of gold mineralization which is located 500m north of
the MG gold deposit (Figure 1). As with the MG and Central gold deposits, the zone of primary
mineralization within intrusive rocks is overlain by an extensive weathered layer consisting of near-
surface sediments and underlying saprolite (weathered intrusive rock). Both types of material are
considered gold-in-oxide material. A preliminary Inferred resource estimate of 3.73Mt @ 0.5 g/t gold
was calculated for the gold-in oxide material only at Machichie Main and was released in October 2024
(see press release October 21, 2024).
Figure 1: Map showing location of known gold-in-oxide blankets with resources; Central, MG, PDM
and Machichie Main. The recently identified Jerimum Cima gold-in-oxide blanket is also shown but
as yet has no resources. Machichie Main is located just 500m north of the MG gold deposit and
3.5km NW of the MG gold deposit.
* Only Indicated resources at Central and MG were considered in the PFS released on 21st October
2024. The main exploration targets (yellow dots) and distribution of historic placer gold workings (pale
yellow outlines) are also shown.

The main objective of the current program is to upgrade a significant portion of the current Inferred
resources to Indicated status so they can be included in the mine plan for the heap-leach starter
operation. The current program of drilling and trenching is also aimed at shedding light on the underlying
primary mineralized zone in the intrusive rocks and collecting additional material for a series of
metallurgical column-leach tests.
Four trenches have been developed recently at Machichie Main to obtain samples for metallurgical
testing and further define mineralization in the oxide zone. Results have been received on 2 (CT051 and
CT052) of the 4 trenches to date. Trench CT051 was excavated over the central part of the Machichie
Main gold deposit, over an interval of 20m and returned
20m @ 3.6 g/t gold
including
4m @ 15.7 g/t
gold
in weathered gold-in-oxide saprolite material (Figures 2 and 3). Mineralization is open to the north
and south.
The mineralized zone cut in trench CT051 is almost certainly the same mineralized zone cut at depth in
drill holes DDH279 (
16.6m @ 1.9 g/t gold including 1m @ 29.7 g/t gold
), DDH300 (
15.7m @ 1.6 g/t
gold
) and DDH301 (
12.2m @ 1.4 g/t gold
) (Figure 3).
Trench CT052 was excavated 150m west of trench CT051 and returned
7m @ 0.8 g/t gold
(Figure 2).
The mineralized interval is again open to the north and south.
These results confirm the presence of significant high-grade gold mineralization within gold-in-oxide
material at Machichie Main and bode well for the possible inclusion of additional Indicated resources
from Machichie Main into an updated mine plan for the heap leach starter operation at Cuiu Cuiu.
Results are currently pending from two additional trenches at Machichie Main CT053 and CT054.
Results were received on 8 RC drill holes (RC494 to RC498, RC500 to RC501 and RC503) at
Machichie Main which were all drilled on the margins of the gold-in-oxide zone to determine the extent of
the near-surface mineralization. All of the holes intersected multiple zones of mineralization (Table 1,
Figure 2).
Several of the holes cut significant intercepts within the gold-in-oxide material, e.g. 10m @ 0.42 g/t gold
from surface in RC497. However, a number of excellent results were returned from the underlying primary
intrusive material including
4m @ 3.9 g/t gold including 1m @ 10.6 g/t gold
in RC497 and
4m @ 3.1
g/t gold including 1m @ 10.6 g/t gold
in RC496. Other notable results included
7m @ 1.5 g/t gold
from RC494,
7m @ 1.2 g/t gold
from RC495, and
1m @ 9.9 g/t gold
and
1m @ 7.3 g/t gold
from
RC503.
Holes RC496 and RC497 were drilled 50m apart and intersected the same mineralized zone along
strike with similar grades and thicknesses. Similarly, the mineralization intersected in holes RC494 and
RC495 is the same zone again returning similar grades and thicknesses along strike. Thus far the infill
drilling at Machichie has confirmed continuity of grade and thicknesses along strike and at depth into the
primary intrusive, affirming potential to upgrade the Inferred resources.
RC drilling with 2 rigs continues with results pending on an additional 38 holes.

project also contains Inferred resources of 13.63Mt @ 1.04 g/t gold (455,100oz) in fresh basement
material and 12.22Mt @ 0.39 g/t gold (151,608oz) in oxide material. The resource estimate for the
primary material is based on the NI 43-101 technical report dated 12
th
October 2022.The resource
estimate for the oxide material is based on an NI 43-101 technical report dated 21

October 2024.
The Tapajós Gold Province is the site of the largest gold rush in Brazil's history which according to the
ANM (Agência Nacional de Mineração or National Mining Agency of Brazil) produced an estimated 30
to 50 million ounces of placer gold between 1978 and 1995. Cuiú Cuiú was the largest area of placer
gold workings in the Tapajós and produced an estimated 2Moz of placer gold historically.
