Cabral Identifies In-situ Vein Mineralization at Alonso
Target, Cuiú Cuiú, and Expands Size of Gold Anomaly
Vancouver, British Columbia--(Newsfile Corp. - April 1, 2020) -
Cabral Gold Inc.
(TSXV: CBR)
("Cabral" or the
"Company")
is pleased to announce that it has identified a vein containing visible gold mineralization at the Alonso target. The
Company is also pleased to provide a further update regarding the ongoing regional exploration work at the Cuiú Cuiú project in
Brazil.
Highlights
Trenching has identified visible gold in an E-W trending quartz vein structure located adjacent to the area where 24 rock
samples from boulders returned highly anomalous gold values ranging from
11.6 to 200.3 g/t gold
. A composite grab
sample of vein material excavated from this vein returned
15.8 g/t gold
In addition, sheeted quartz veinlet mineralization was observed in bedrock 25m north of the outcropping vein structure
described above suggesting the presence of a broader mineralized zone associated with a prominent E-W trending
magnetic anomaly. This style of mineralization is typical, albeit higher grade, of the known mineralization which comprises
the existing MG and Central gold deposits at Cuiú Cuiú as well as the Machichie target which was discovered during early
2019
Reconnaissance work to the east of the area where the original high-grade quartz-pyrite boulders were identified, has
returned anomalous gold values in soils up to 900m to the east. Additional quartz-pyrite float material has also been
identified up to 1.3km east of the high-grade quartz-pyrite boulders, further extending the Alonso target area to the east
Alan Carter, President & CEO stated
"The identification of visible gold in an outcropping quartz vein adjacent to the area of
abundant quartz-pyrite boulders at Alonso is an important step forward in identifying the source of the quartz boulders which
recently returned gold values of 11.3 to 200.3 g/t gold. Furthermore, the possible presence of a broad mineralization halo
extending at least 25m to the north of the main vein structure suggests that the style of gold mineralization at Alonso is
similar to the two main existing gold deposits at MG and Central. This further supports the conclusion that Cuiú Cuiú is an
emerging district containing multiple gold deposits".
Alonso Target
Recent trenching has been conducted at the Alonso target where a series of large angular quartz boulders returned gold values
of 11.6 to 200.3 g/t gold
. The trench extended over 31.4m in a NNW direction along the western flank of the alluvial workings
where the quartz boulders were discovered. Excavation through a shallow layer of cover located an in-situ quartz-pyrite vein
containing visible gold
.
The vein that is exposed is 1.3m in width, trends E-W and is coincident with a pronounced E-W trending
magnetic anomaly. It is not known at this point if this vein is the source of the high-grade boulder samples, since most of the
boulders are located up slope from the outcropping vein and are upstream beyond the northern limit of the trench.
A first attempt at trenching 8m to the east of the final site was abandoned, as the site proved to be waterlogged. A composite
grab sample of vein material excavated from this attempt returned a grade of
15.8 g/t gold
. However, continuous channel
sampling was feasible in the revised position shown in Figure 1. The channel sample across the vein interval returned 1.3m @
7.1 g/t. The southern sector of the trench was barren. The northern limit of the trench terminated within a low-grade halo (4m @
158 ppb gold). The halo is known to extend further north, with narrow millimeter scale quartz veinlets observed up to 25m north of
the main vein structure. Most of the boulders occur upstream to the north and remain untested.

Extension of the trench further to the north was not possible since the ground is currently water-logged. This will be reassessed in
the dry season. Achieving continuous sampling to the north across the magnetic anomaly will be important to determine if more
than one vein is present to confirm the source. Other mineralized systems such as the existing MG and Central gold deposits at
Cuiú Cuiú, as well as the Machichie target, which was discovered during 2019, are known to contain multiple high-grade veins
and mineralized halos.
In addition, results have been returned on a number of additional samples of quartz vein float material with six samples collected
from an area 950m to the west-south-west, returning gold values of 1.0 to 7.7 g/t gold (Figure 2). These samples suggest the
extension of a branch of the Alonso mineralized structure could extend more than 950m to the WSW.
Recent reconnaissance work conducted to the east of the boulder field has identified additional quartz-pyrite vein material up to
1.25km east of the boulder field as well as anomalous gold-in-soil geochemical samples, confirming a probable extension of the
mineralized zone at least 1km to the east (Figure 2).
The Alonso area is covered by a thin sequence of recent post-mineral sediments and ferricrete which cover the underlying
intrusive rocks and result in significantly reduced geochemical responses. Nonetheless, high levels of gold were returned in pan
concentrates from streams for more than a kilometer both west and east of the discovery, and appear to correspond to
pronounced east-trending lineaments within the magnetics.

Covid-19 measures
As a result of the Covid-19 outbreak and in order to protect staff and the local community from potential infection, Cabral has
temporarily closed both of its offices in Vancouver, Canada and Itaituba, Brazil and all staff are currently working from home. In
addition, the Company has suspended all field work at the Cuiú Cuiú project in Brazil for at least 14 days following local health
authority recommendations but will continue to provide support to the local community.
The company is providing medical support and supplies to the community of Cuiú Cuiú and continues to maintain a medical
outpost in the community to continue serving our local partners, staff and the broader community.
Alan Carter, President & CEO stated,
"Our priority is the health and safety of our employees, their families and the local
community. Cabral Gold will continue to monitor the Covid-19 situation and adjust plans as the situation evolves. We would
like to thank our employees, partners and all stakeholders for their understanding and support, and we look forward to
resuming field operations as soon as possible".
Results are pending on numerous soil, auger top-of-bedrock, and rock samples from the regional reconnaissance exploration
program and are expected over the next two months. The analytical lab in Brazil continues to operate but with restricted transport
and logisitical options which will result in some delays to the reporting of results.
About Cabral Gold Inc.
The Company is a junior resource company and is 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 located in
the Tapajós Region within the state of Pará in northern Brazil.
The Tapajós Gold Province is the site of the largest gold rush in Brazil's history producing an estimated 30 to 50 million ounces
of placer gold between 1978 and 1995. Cuiú Cuiú was the largest garimpo in the Tapajós and produced an estimate 2Moz of
placer gold historically.
