Cabral Gold Inc.

("Cabral"

)
announces the initial results of an ongoing auger drilling program sampling saprolite within the Central —
Pau de Merenda target corridor at the Cuiú Cuiú Project, Pará State, northern Brazil.
Highlights
Recent saprolite (weathered bedrock) sampling by auger drilling and pitting beneath deep cover in the Central - Pau de
Merenda target corridor returned highly anomalous results in both gold counts and geochemical analyses
Individual top-of-saprolite samples returned peak values of
18.7 g/t Au
. Gold counts in places exceeded 100 per sample
These results define a mineralized corridor extending for
a minimum of 4km
in a NW-SE direction (open along strike).
The Central deposit, which contains 485,000oz (5.9MMt @ 0.9g/t Au + Inferred resources of 8.7MMt @ 1.1g/t Au),
currently occupies the southeastern 1.2km of this 4km long anomaly
Background
The Cuiú Cuiú Project hosts the largest of the historical alluvial gold camps in the Tapajós region of northern Brazil, having
yielded an estimated 2MMoz of gold from the overall 20-30MMoz gold produced during the Tapajós gold rush
1
. Alluvial workings
extend over 850ha on the property but are largely exhausted. The few remaining artisanal workers now process palaeo-valley
placer deposits and in places exploit high-grade saprolite mineralization. The Company's current program is designed to
evaluate newly identified prospects, to prioritize drill targets and to build upon the existing resource inventory

.
The Pau de Merenda — Central corridor is a NW-trending belt which parallels the trend of the Tocantinzinho Lineament, a major
regional structure aligned with deposits such as Eldoraldo Gold Corporation's Tocantinzinho deposit and Serabi Gold plc's
Palito underground mine. Cabral Gold's Central Deposit lies along this trend and is principally characterized by a stockwork vein
system with wide-spread alteration extending 1.2km along strike and approximately 100m in width. The Central deposit currently
contains 485,000oz or
Indicated
Resources
of
5.9
MMt @ 0.9g/t Au + Inferred
R
esources
of 8.7MMt @ 1.1
g/t Au
.
Pau de Merenda is located along trend and 3km NW of the Central deposit and is defined by a corridor of demagnetization
approximately 2,000 m long by 800m wide. An associated >100ppb gold-in-soil anomaly is centred around a NW-trending ridge
flanked by extensive artisanal alluvial workings. Results from historical reconnaissance drilling in a small part of the area
included 47.1m @ 1.8 g/t Au, 30.2m @1.1g/t Au and 8.5m @ 5.1 g/t Au.
Until the current auger drilling program, the trends have
not been well understood due to deep soil cover that partially masks the bedrock geochemical response.

Current Program
The current program of work has involved an initial campaign of channel sampling, pitting and auger drilling in the Central — Pau
de Merenda corridor, to provide a more precise framework to determine drill targets. Additional trenching and channel sampling
are still in progress.
The auger drilling and pitting program is directed at tracing the mineralized trends under thick overburden cover using saprolite-
cover interface geochemistry.
Samples were taken from the top few meters of the saprolite, which in some areas is covered by a
thick residual soil profile, and in others by a thick widespread transported alluvial cover sequence. The latter effectively masks
underlying gold in bedrock and shows no significant gold-in-soil surface anomaly. The cover sequence is typically 8m thick, or
less, but in a few areas exceeds 20m in thickness.
A 3kg split was taken from all saprolite samples at site. The remainder was initially washed and panned on site and the gold
colours for each sample were counted.
The latter fraction averaged 42kg (more than ten times larger than the sample sent for
analysis). This not only provides a low cost and rapid means of assessing and mapping the main mineralized trends under
cover, but also provides a larger sample in a saprolite rock where gold is sometimes coarse.
Initial results from top-of-saprolite interface sampling locally returned gold counts exceeding 100, and define an anomalous
corridor extending for a minimum of 4km, essentially connecting the Central deposit and the Pau de Merenda targets. The zone
is still open along strike to the NW and SE (Figure 2).

Similarly, the geochemical analyses from smaller split samples of the same intervals indicates the presence of a narrower more
constrained anomalous zone defined by the 0.1 g/t gold contour. They also support the minimum 4km long trend (Figure 3).
Maximum geochemical values returned from the top-of saprolite sampling were
18.7 g/t Au
.

Figure 4 shows both the geochemical fraction superimposed on the gold count data which, together, strongly suggest the
presence of a wider and much longer mineralized corridor that encompasses the Central deposit and the Pau de Merenda
target, than was previously envisaged. Results are currently pending on a series of trenches testing parts of this mineralized
corridor where artisanal workings have exposed the top of the saprolite below the cover sequence.

Alan Carter, President & CEO, commented, "The auger results from the Central - Pau de Merenda corridor area are very
compelling and strongly suggest the presence of a significantly larger area of gold mineralization than is suggested by the
current resource at Central. These results come close on the heels of recent high-grade surface rock assay results from the
Jerimum Cima target area (see news release of June 19, 2018), which are also located outside the existing resource. I would
like to congratulate our exploration team, led by Adrian McArthur, on their continued success, and look forward to additional
results from other targets at Cuiú Cuiú in the coming weeks and months."

Notes
Samples are collected via a mechanical auger with advances
of
20-30cm. Sampling intervals are separated according to
lithology. Drilling continues over 3m into the saprolite. The saprolite sample reduced using a ten-slot riffle splitter feeding two
collection trays. The splitter and trays are cleaned of any residue between samples. A split sample of ~3kg is sent the SGS in
Brazil for sample preparation and analysis. The residual sample mass (on average ~42kg) is screened on site to produce a
hand-pan concentrate of the dense mineral fraction. Gold counts are visually determined, and
samples are archived on site.
Gold analysis has been conducted
by
SGS method
FAA505
(fire assay of
5
0g charge), with
higher grade
samples
checked
by
FAA525
.
Analytical quality is monitored by certified references and blanks. Until dispatch, samples are stored
under
the
supervision the C
ompany's
exploration office. The samples are couriered to the assay laboratory using a commercial
contractor. Pulps are returned to the Company
and archived
