Diamond drilling advances at the Machichie Target, Cuiú Cuiú Project.
Channel sampling returns 52.5 g/t Au over 0.9m and 23.8 g/t Au over 1.35m
Vancouver, British Columbia – January 29, 2019 – Cabral Gold Inc. (“Cabral” or the
“Company”) (TSXV: CBR OTC: CBGZF) is pleased to announce that it has completed its first
two diamond drill holes at the Machichie target at the Cuiú Cuiú Project, Pará State, northern
Brazil. The high-grade potential of the Machichie target was first recognised in mid-2018 through
channel sampling of artisanal workings (see pr ess release dated July 19, 2018). Since then, an
auger geochemical program has defined a broader gold anomaly extending along strike from the
workings, coincident with a significant copper-molybdenum (“Cu-Mo”) anomaly, and a program of
channel sampling of structures in the main artisanal workings has continued.
The east-west structures of the Machichie tar get have never been previously drilled. The target
is located just 500m north of Cabral’s MG gold deposit which is one of four deposits with defined
resources at Cuiú Cuiú.
Highlights
The first two diamond drill holes have been completed at Machiche, successfully tracing
quartz veins containing-pyrite approximately 50m vertically below the base of artisanal
workings. Core is being cut and samples will shortly be sent to the laboratory for analysis.
New assay results from surface samples collected in late 2018 in and along strike from
these workings include:
o A grab sample returned 356g/t Au, 198g/t Ag, 1% Cu and 0.1% Mo, collected from
stockpiles at the principal shaft
o A channel sample of a vein 70m to the east along strike returned 52.5 g/t Au over 0.9m
o A channel sample of a vein 300m to the west along strike returned 23.8 g/t Au over
1.35m
Top-of saprolite auger geochemical drilling outlined a significant gold anomaly extending
more broadly along strike from the limit of the artisanal workings. Together with recent
sampling, the results suggest the Machichie target extends over at least 1.1km.
Unlike all the other targets identified thus far at Cuiú Cuiú, the auger drilling has also defined
a significant Cu-Mo anomaly which is coincident with the gold (“Au”) anomaly. This is best
developed to the east where a strong IP chargeability anomaly is also present.

Machichie Target
The Machichie target is located just 500m north of the MG deposit. MG is currently the second
largest gold deposit known at Cuiú Cuiú, with an Inferred Resource of 8.6MMt @ 1.45g/t Au
(0.4MMoz of gold) 1 .
Machichie was selected as a high priority drill target following the mid-2018 discovery of high-
grade gold mineralization from recently developed artisanal shafts. Altered rocks in the muck-pile
from the workings contain considerable pyrite, along with molybdenite, scheelite, and minor
chalcopyrite. A composite grab sample returned 336 g/t Au from a 1m wide quartz-pyrite vein in
the principal shaft in the area. Results from channel sampling in subsidiary shafts and galleries
in weathered bedrock along strike included 54.6 g/t Au over 0.80m, 13.8 g/t Au over 1.5m, 13.2
g/t Au over 0.75m and 5.8 g/t Au over 1.75m. A recent grab sample from stockpiles of the principal
shaft returned 356 g/t Au, 198 g/t Ag, 1% Cu and 0.1% Mo (Figure 1).

locations, along with photos of samples and workings.
The diamond drill program has commenced with two diamond drill holes completed on section
553005E. These drill holes have traced the structure in bedrock to a depth of 50m vertically below
1 Micon NI 43-101 amended resource estimate dated 19 December 2018.

the base of the principal working (Figure 2). The workings extend to a depth of 17m below surface
and have recently been terminated at the water table.
The Machichie structure is characterized by a subtle east-west trending magnetic low which is
coincident with the high-grade mineralization observed on surface. Additional magnetic lows
along strike to the east and west of the artisanal shafts were targeted with follow up auger
sampling and suggest that the structure extends at least 1.1km along strike.
In late 2018, efforts were aimed at determining the strike extent of the Machichie structure. This
work has resulted in the identification of significant mineralization including 23.8 g/t Au over
1.35m and 2.1 g/t Au over 1.05m located 350m along strike and west of the main artisanal shaft.

In addition, results from four lines of shallow auger holes which were completed to the west of the
main artisanal shaft have revealed a strong coincident Au and Cu anomaly with values up to
203ppm Cu and 200ppb Au. Rock grab samples collected approximately 175m further west of
the most westerly auger line returned values of 5.5 g/t and 3.1 g/t Au, suggesting the Machichie
structure remains open to the west.
In addition, recent channel sampling east of the main artisanal shaft at Machichie returned 52.5
g/t Au over 0.9m from a position 70m east of the principal shaft.
An additional four diamond drill holes are planned at Machichie to the east and west of the initial
two holes which were drilled directly under the main artisanal shaft.
Machichie East Target
Shallow auger drilling below thick overburden cover east of the artisanal workings at Machichie
was conducted in late 2018 and has revealed an even stronger and larger Au-Cu-Mo anomaly

than that to the west. A broad gold anomaly is evident over 300 x 350m with values up to 325ppb
gold located approximately 300m east of the main artisanal shaft (Figure 3) and is coincident with
elevated Cu values up to 207ppm (Figure 4) and a well-defined Mo anomaly with values ranging
from 10 – 152ppm Mo (Figure 5). Background Mo values throughout the Cuiú Cuiú project area
are generally below the detection limit of 3ppm.
The Au-Cu-Mo anomaly at Machichie East is coincident with a magnetic anomaly, and more
importantly a well-defined chargeability anomaly at depth which was defined by a historic IP
survey. A strong correlation exists at the MG deposit between zones of high chargeability and
high-grade parts of the deposit.
The Machichie East target will be drill tested following completion of drilling at Machichie.

Alan Carter, President & CEO commented “The recent surface channel sampling results and the
auger geochemical target suggest the presence of a significant mineralized structure to the
immediate north of the MG deposit. The presence of elevated copper and molybdenum values in
conjunction with the gold, is unique so far amongst the various targets at Cuiú Cuiú. The diamond
drill campaign will add valuable information regarding the depth projection of the Machichie
structure and the significance of the copper-m olybdenum-gold signature at Machichie East. We
look forward to the drill results of the program”.

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 owns the Cuiú Cuiú gold project, which covers the largest of the historical placer
gold camps in the Tapajós region of northern Brazil, having yielded an estimated 2M oz of gold
from the overall 20-30M oz gold produced during the Tapajós gold rush. Placer workings cover
over 850ha on the property but are largely exhausted. The few remaining artisanal workers now
process gold from palaeo-valley placer deposits and in places exploit high-grade gold
mineralization from quartz veins in saprolite (shallow highly weathered bedrock).
Cabral reported an updated NI 43-101 Mineral Resource Estimate in December 2018 totalling
5.9M tonnes grading 0.9 g/t Au (Indicated) and 19.5M tonnes grading 1.2 g/t Au (Inferred), or
0.2M ounces and 0.8M ounces of gold, respectively. That estimate was based on four deposits
drilled prior to the cessation of exploration in 2012.

Notes
Gold analysis has been conducted by SGS method FAA505 (fire assay of 50g charge), with higher
grade samples checked by FAA525 or screen fire assay. Multi-element analysis is conducted by
four acid digest and ICP-OES analysis. Analytical quality is monitored by certified references and
blanks. Until dispatch, samples are stored under the supervision the Company's exploration
office. The samples are couriered to the assay laboratory using a commercial contractor. Pulps
are returned to the Company and archived. Channel sampling is conducted using a hand-
trenching tool over exposed faces to maintain a consistent sample. The high-grade Machichie
sample was collected in run-of-mine stockpiles from the artisanal processing operation.
The historical induced polarization survey was a 3D IP survey conducted for Magellan Minerals
Ltd. in 2012 by SJ Geophysics Ltd. The survey used a GDD TX II Transmitter and a SJ-24 Full
Waveform receiver. The survey was conducted on 100m spacings lines with a dipole size of 50m
and an array length of 500 to 750m. Geophysical exploration targets are preliminary in nature and
not conclusive evidence of the likelihood of a mineral deposit.
Under the agreement with the Cuiú Cuiú condominium, local artisanal operators can process
mineralization to a depth of 30m, unless otherwise negotiated. Shafts generally stop at or above
the depth of the water-table. Historical drilling results are reported as down-hole length weighted
intersections unless otherwise stated.
