TSX-V: SAO

South Atlantic Gold Announces Maiden Resource for the Pedra Branca Project, Brazil;

100% Property Ownership Attained.

Kelowna, British Columbia, June 28, 2021 - SOUTH ATLANTIC GOLD INC. (TSX-V: SAO) (“South Atlantic”

or the “Company”) is pleased to report that Pedra Branca’s Maiden Resource has been completed and is

presented under National Instrument (“NI”) 43 -101 technical report standards. The resource was

completed by the consolidation of historical drilling and Phase 1 Reverse Circulation (“RC”) drilling results

with an average depth of 41.2 meters (“m”).

Highlights

• Completed 100% earn -in of the Pedra Branca Project (“Pedra Branca” or the “Project”) from

Jaguar Mining Inc. (“Jaguar”) through the delivery of the NI 43-101-compliant technical report.

• Maiden mineral resource:

o A total of 10,523 samples were included in the resource calculation before the cut-off

date of February 19th, 2021. As such, all remaining 8,188 (43% additional samples) were

not included in the resource and are considered only as exploration results.

o Inferred mineral resource includes (click here for complete inferred resource tables):

▪ Oxide: 900,000 tonnes (“t”) grading 1.35 grams per tonne (“g/t”) gold (“Au”) for

39,000 oz Au

▪ Fresh: 3,142,000 t grading 1.40 g/t Au for 141,000 oz Au

▪ Total: 4,042,000 t grading 1.38 g/t Au for 180,000 oz Au

o Over 39 mineralized N20E/40SE zones were individualized, along a 12km strike length

with an average thickness of 4 m, over the 3 main targets: Igrejinha, Coelhos-Queimadas

and Mirador (click here for table of ore grades at these Targets).

o The Phase I RC drilling was completed to an average depth of 41.2 m. From the historical

drilling, higher grades have been reported from deeper intercepts with a total of 93

historical Diamond Drilling (“DD”) holes also included in the maiden resource calculation.

Douglas Meirelles, CEO stated, “The primary objective of this technical report was to provide a NI 43-101-

compliant report to Jaguar Mining Inc. (“Jaguar”) in order to complete our additional 25% earn-in to attain

full ownership of the Pedra Branca Project. As such, our focus was to deliver a maiden resource report as

quickly as possible during our Phase I exploration program. A cut-off date for the resource calculation was

set at February 28th, 2021 in order to enable sufficient time to complete the report and have Jaguar review

prior to mid-2021.

Our team was very successful, and with a USD 1 million exploration program, defining a total of 39

mineralized zones along the entire 12 km mineralized trend. Going forward, the Phase II program will be

designed to further delineate and possibly bridge the gaps between the mineralized areas and transition

the current resource to an advanced stage asset as set by the mining concession issued by the National

Mining Agency of Brazil.”

TSX-V: SAO

The company will work with Jaguar to complete the required government processes to transfer the Pedra

Branca asset to South Atlantic Gold’s subsidiary in Brazil.

The Company is also pleased to report that a n additional tenement located in the center of the Project

was recently acquired. This new tenement increases the Pedra Branca land area to 39,906 hectares. The

location and acquisition of this new tenement was deemed essential to co nsolidate the Company’s

ownership along the entire mineralized trend.

The data from the Phase I exploration program was obtained from a mineralized trend of approximately

12 km. Some of the exploration work was required to maintain the tenements in good legal standing with

the Brazilian mining and exploration agencies. Because the assay results and drill holes were widely

spread, the parameters for the for the resource estimate are conservative. Nevertheless, they included:

• Three block models over 39 mineralized bodies were prepared based on the targets of Coelhos-

Queimadas, Mirador and Igrejinha

• A capping of 12 g/t Au was used to reduce the influence of outlier sample data

• A cut-off grade of 0.4 g/t Au

Resource Estimate

The mineral resource estimate is that material within the block models using a cut-off grade of 0.4 g/t Au.

The effective date for the mineral resource is 16 th of March, 2021 and a corresponding technical report

disclosing the mineral resource estimate in accordance with NI 43 -101 has been prepared by RBM

Consultoria Mineral for the Company endorsed by Mr. Rodrigo Mello, FAusImm. Mr. Mello is also a QP as

defined under NI 43-101. South Atlantic will file the technical report on SEDAR at www.sedar.com within

45 days of this news release.

-Figures have been rounded to the appropriate level of precision for the reporting of mineral resources.

-All figures are in metric tonnes.

-Mineral Resources that are not Mineral Resources do not have demonstrated economic viability.

-The estimate of mineral resources may be materially affected by geology, environment, permitting, legal

title, taxation, sociopolitical, marketing or other issues.

-Inferred Mineral Resources have been estimated in accordance with the definitions adopted by the

Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) and incorporated in NI 43 -101,

“Standards of Disclosure for Mineral Projects” by Canadian securities regulatory authorities.

-An Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality

can be estimated on the basis of geological evidence and lim ited sampling and reasonably assumed, but

not verified, geological grade and continuity.

Phase II Exploration Program

A Phase II Exploration program is proposed for the 3 main targets that lie along the 12 km mineralized

trend. The primary goal of Phase II is to focus on an in -fill drilling program, commencing with the 39

mineralized bodies that have been identified in the Phase I program. Figure 1 in the Annex illustrates the

three main targets in the 12km mineralized extension including Igrejinha, Coelhos -Queimadas and

Mirador and shows that some outlines of mineralized bodies are starting to take shape. Additionally,

there are areas which due to limited time and budget in Phase I, have no exploration results. Phase II is

designed to both explore those areas not covered in Phase I and to provide some along-strike extensions

to these targets. Most of this work can be accomplished with trenching and RC drilling as was done in

Phase I. Additionally, core drilling will be conducted to test potential mineralization at depths.

The Phase II exploration program will also enable the Company to maintain all tenements in good legal

standing through completion of exploration work and filing of required reports to the Brazilian authorities.

Over 23 targets and areas of interest at Pedra Branca have not been drilled or previously explored. These

TSX-V: SAO

areas require some geochemical sampling and trenching to determine their continuing value over the 40

km mineralized trend of the Troia Greenstone Belt.

A technical 3-D video will soon be up on our website ( www.southatlanticgold.com) to complement

written descriptions of the Pedra Branca Project in press releases and on the website. This video not only

puts into perspective the significant size of the Project, but also illustrates the infrastructure (power, good

roads, commerce centers, and manpower), primary exploration targets (Coelho-Queimadas, Igrejinha and

Mirador) and the potential upside and increase in mineral resources expected with the Phase II program

combined with the remaining 43% of samples resulting from the Phase I program that was not included

in this mineral resource estimate due to time constraints.

Other highlights of the Phase II program include:

• RC in-fill drilling will be focused on further delineation of the geology and mineralization of the

gaps between the targets. RC drilling will also be conducted on the potential targets identified

along the 30 km southern extension of the mineralized trend that did not receive any drilling

during the Phase I exploration program.

• Diamond core drilling will be conducted to provide insight into lithology, structural geology,

controls on mineralization, grades and grade variability at depth. Oriented core will be used to

help in the understanding of the structural geology and controls of mineralization.

• Detailed 3D geologic and structural modeling.

• Mineral resource estimate to be updated to include the 8,188 additional assay results from the

Phase I and additional samples from the Phase II exploration program .

• Trenching has been demonstrated to be a very efficient and cost-effective method to identify the

sub-outcropped mineralized orebodies and will be the exploration technique to precede drilling

in areas that were not explored in the Phase I program.

• Continuation of the community engagement program.

Quality Assurance / Quality Control

The Quality Assurance and Quality Control (QA/QC) protocol adopted by South Atlantic was comprised of

a series of industry standard procedures designed to monitor the precision and repeatability of the

reported assay results and identify potential problems at the laboratory. No drill hole from the project

was sampled without a concomitant QA/QC program assuring the quality of the results. The QA/QC

program developed by SAG has been inserted 4% of field Blanks, 4% field duplicates and 4% standards

from Rocklabs and ITAK with range of 0.8 g/t to 8.0 g/t Au.
