Machichie Main Gold Deposit, Cuiú Cuiú Gold District, Brazil
Cabral Gold Drills 2m @ 52.3 g/t Gold at the
Machichie Main Gold Deposit, Cuiú Cuiú Gold
District, Brazil
Vancouver, British Columbia--(Newsfile Corp. - May 13, 2025) -
Cabral Gold Inc. (TSXV: CBR) (OTC
Pink: CBGZF) ("Cabral" or the
"
Company
") is pleased to announce results from eleven additional
reverse circulation ("RC") drill holes at the Machichie Main gold deposit within the Cuiú Cuiú Gold
District, Brazil.
Highlights
Drill hole RC0499A returned
2m @ 52.3 g/t gold
from 41m depth within highly altered intrusive
rock in the western part of Machichie Main gold deposit. This is a previously unrecognized zone of
high-grade gold mineralization
Drill hole RC0529 Intersected multiple mineralized intervals including
9m @ 0.72 g/t gold
from
28m depth and
25m @ 0.93 g/t gold
from 43m depth. Both intercepts are in intrusive rock
Additional drill results from Machichie Main include;
18m @ 0.87 g/t gold
from surface in blanket sediments in RC530,
8m @ 0.62 g/t gold
from surface in blanket sediments in RC517
8m @ 0.46 g/t gold
from 52m depth in altered intrusive rocks in RC523
8m @ 1.26 g/t gold
from 13m depth in saprolite and
10m @ 0.62 g/t gold
from 33m depth
in altered intrusive rocks in RC528
Alan Carter, Cabral's President and CEO commented
, "These latest drill results from the Machichie
Main gold deposit indicate the presence of a new previously unrecognised high-grade zone
immediately south of the main gold deposit. These results come on top of recent very high-grade
results at the nearby Machichie NE target located 150m to the north-east of Machichie Main.
Furthermore, the presence of excellent gold values in the near surface blanket sedimentary material
and saprolite in several drill holes augers well for the expansion of the current gold-in-oxide blanket at
Machichie Main and its potential inclusion in revised resource and reserve estimates which are
expected in the next few weeks as part of the updated PFS on the gold-in-oxide starter operation."
Brian Arkell, Cabral's VP of Exploration and Technical Services noted:
"Machichie is a very significant
discovery in that it potentially provides a higher-grade source of feed for the proposed oxide heap
leach process plant. We've hit several higher-grade zones of near-surface mineralization along the
900-metre strike length and our drilling, while still widely spaced, is showing good continuity. This
near-surface mineralization remains open in almost all directions and projects downward as well, into
the primary zone. We are working on an updated resource model and are currently completing mine
design work where we expect to add Indicated Resources to the Oxide Project PFS."
Machichie Main Drill Results
The Machichie Main zone is an E-W trending zone of gold mineralization which is located 500 metres
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 3.73 million tonnes ("Mt")
@ 0.5 grams per tonne ("g/t") gold was calculated for the gold-in oxide material only at Machichie Main
and was released in October 2024 (see press release dated October 21, 2024). Thus far, no resource
has been calculated for the primary gold deposit at Machichie Main but drilling and trenching to date has
outlined the mineralized zone over 900m strike extent.
Figure 1 Map showing location of known gold deposits at Central, MG and JB. The location of new
discoveries at PDM, Machichie NE and Machichie Main are also shown. Machichie Main is located
just 500m north of the MG gold deposit and 3.5km NW of the Central gold deposit.

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.
Results were received on 11 RC drill holes (RC499A, RC517, RC523, RC527 to RC530, RC532 to
RC534 and RC536) at Machichie Main. The holes were primarily aimed at upgrading and expanding
existing resources within the gold-in-oxide zone and shedding light on the location of the mineralized
zones within the underlying fresh granitic rocks. (Table 1, Figure 2).

Drill hole RC499A was drilled on section 552960E south of the Machichie Main mineralized zone where
previous trenching returned
20m @ 3.6 g/t gold
in CT051 (see press release dated
March 13, 2025)
and drilling returned
16.6m @ 1.9 g/t gold
including
1m @ 29.7 g/t gold
in DDH279 and
15.7m @ 1.6
g/t gold
in DDH300. RC499A cut a previously unrecognized zone of higher-grade gold mineralization
which returned
2m @ 52.3 g/t gold
from 41m depth in fresh intrusive rocks (Section AA', Figures 2 and
3, Table 1). This higher-grade mineralized zone is located within the Machichie Main fault zone but
occurs between the known mineralized zones and represents an entirely new zone of higher-grade
mineralization. It is currently open in all directions and will require further drilling to determine the extent of
the mineralized zone.

Excellent results were also returned from RC0529 which was drilled on section 552848E in the western
part of the deposit and returned multiple mineralized intervals including
9m @ 0.72 g/t gold
from 28m
depth and
25m @ 0.93 g/t gold
from 43m depth including
6m @ 2.01 g/t gold
from 46m depth and
5m
@ 1.52 g/t gold
from 60m depth. Both intercepts are in intrusive rock (Section BB', Figures 2 and 4,
Table 1).

Excellent results were also returned from several other holes, primarily in the near-surface gold-in-oxide
material (Figure 2, Table 1). Notable intercepts include;
18m @ 0.87 g/t gold
from surface in blanket sediments in RC530,
8m @ 0.62 g/t gold
from surface in blanket sediments in RC517
8m @ 0.46 g/t gold
from 52m depth in altered intrusive rocks in RC523
8m @ 1.26 g/t gold
from 13m depth in saprolite and

from 33m depth in
altered intrusive rocks in RC528

About Cabral Gold Inc.
The Company is a junior resource company engaged in the identification, exploration, and development
of mineral properties, with a primary focus on gold properties located in Brazil. The Company has a
100% interest in the Cuiú Cuiú gold district located in the Tapajós Region, within the state of Pará in
northern Brazil. Three main gold deposits have so far been defined at the Cuiú Cuiú project which
contain National Instrument ("NI") 43-101 compliant Indicated resources of 12.29Mt @ 1.14 g/t gold
(450,200oz) in fresh basement material and 11.11Mt @ 0.48 g/t gold (171,883oz) in oxide material. The
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 October 12, 2022.The resource
estimate for the oxide material is based on an NI 43-101 compliant estimate released on October 21,
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.
