Toronto, Ontario, April 26 2021 – Unigold Inc. (“Unigold” or the “Company”) (TSX -V:UGD; OTCQX:
UGDIF; FSE:UG B1) is pleased to provide the results from the independent Preliminary Economic
Assessment (“PEA”) prepared in accordance with National Instrument 43 -101 – Standards of
Disclosure for Mineral Projects ("NI 43 -101") on its 100% owned Candelones Oxide Project in the
Dominican Republic.
Joseph Hamilton, Chairman and CEO of Unigold notes: “The Candelones Oxide project has been designed
as a small footprint, environmentally friendly operation that will establish the Company in the local area of
the Dominican Republic. The economics are compelling enough that this is being considered as a stand-
alone operation providing near term cash flow as the Company continues to expand and evaluate the larger
sulphide resource which the Company believes offers a longer -term development opportunity. The
Company will move to rapidly develop both projects over the next few years as it concurrently moves the
oxide project through required community consultation, environmental studies, detailed engineering and

permitting while completing metallurgy, preliminary design and market studies for the sulphide project.
Recent exploration drilling at the Candelones Extension identified additional po tential for oxide resource
expansion to the east of the known deposit while continuing to expand the available sulphide resource.
The resource mined in this PEA includes inferred mineral resources which contribute approximately 27% to
the life of mine production schedule. The Company intends to complete the additional drilling
recommended by our lead consultant, Micon, to rapidly upgrade this inferred resource to measured and
indicated status, allowing it to be included in the planned Feasibility Study. The Company intends to
transition directly into a Feasibility Study on the oxide project as soon as possible. Additional oxide material
has been collected and is being shipped to Canada for large diameter, run of mine column tests to confirm
the recovery assumptions used in the PEA. We are targeting the end of 2021 to have all materials and studies
assembled to allow the Government to proceed with permitting of this project.”
This independent study was prepared by Micon International Limited under the supervision of Mr.
Richard Gowans, B.Sc. P.Eng., President and Principal Metallurgist, Micon International Limited
(“Micon”) and included contributions from the geological and engineering teams at Micon and Halyard
Inc. (Toronto ). These firms provided the mineral resource estimates, design parameters and
operating and capital cost estimates for mine operations, process facilities, major equipment
selection, infrastructure, and project economic analysis . A full technical report will be filed on
www.sedar.com, and will be available on the Company’s website, within 45 days.
The pertinent input parameters and results of the Candelones Oxide PEA Study (Base Case) are
presented in Table 1 to Table 4. Table 5 presents the NPV and IRR sensitivity to variability in gold price,
capital cost, and operating cost. Mineral resources for the Candelones project are shown in Table 6.
Resource Estimate
The PEA is based on the measured, indicated and inferred oxide mineral resource estimated by Mr.
W. Lewis, P.Geo. and Mr. A. San Martin, MAusIMM (CP) of Micon International Limited with an effective
date of August 17, 2020 and is included with a NI43-101F1 Technical Report titled “UPDATED MINERAL
RESOURCE ESTIMATE FOR THE CANDELONES PROJECT NEITA CONCESSION DOMINICAN REPUBLIC”
which is available at www.sedar.com and on the Company’s website. Micon is independent of Unigold
and Messrs. Lewis and San Martin meet the requirements of a “Qualified Person” as established by
the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards for Mineral
Resources and Mineral Reserves (May, 2014).
Cautionary Statement: The reader is advised that the PEA summarized in this news release is intended to
provide only an initial, high-level review of the project potential and design options. The PEA mine plan and
economic model include numerous assumptions and the use of inferred mineral resources. Inferred
mineral resources are considered to be too speculative to be used in an economic analysis except as allowed
for by NI 43-101 in PEA studies. There is no guarantee that inferred mineral resources can be converted to
indicated or measure d mineral resources, and as such, there is no guarantee the project economics
described herein will be achieved.

Mining
The mineral resources used in the mine plan for this PEA outcrop on surface and are contained within
a pit with a maximum depth of approximately 30 metres. The mine has a production rate of 5,000
tonnes per day. Contract mining is assumed using a local, established construction contractor in the
Dominican Republic. The material is free -dig at surface. No drilling or blasting is contemplated in
this study. Approximately 27% of the production is estimated to be transition material.
Processing
A total of 150,000 tpm of material will be extracted and hauled approximately 3 km onto a Run -of-
Mine Heap leach pad. Gold and silver will be recovered in an adsorption-desorption-recovery circuit
and electrowinning cells, with gold room recovery and production of bullion bars. Silver credits are
not included in the financial modelling. No tailings facility is required. Gold recovery estimates for
oxide and transition mineralization are based on a column leach testwork currently ongoing at
Bureau Veritas Commodit ies Canada Ltd. Metallurgical test laboratories, Vancouver, where
preliminary results indicate 87% gold extraction in 30 days for -19 mm oxide mineralization and over
60% gold extraction in 43 days for -12.5 mm transition mineralization. This study uses an average
75% leach recovery with a 10-week leach cycle.

Notes relating to Mineral Resource Estimate
Mineral resources were estimated by Mr. W. Lewis, P.Geo. and Mr. A. San Martin, MAusIMM(CP) of Micon International Limited. ( “Micon”), a Toronto based
consulting company, independent of Unigold. Both Mr. Lewis and Mr. San Martin meet the requirements of a “Qualified Person” as established by the Canadian
Institute of Mining, Metallurgy and Petroleum (CIM) Definition Standards for Mineral Resources and Mineral Reserves (May 2014 ) (“the CIM Standards”). The
estimate is based on a long-term gold price of US$ 1,500 per ounce and economic cut -off grades 0.30 g/t Au (OXIDE), 0.60 g/t (TRANSITION AND SULPHIDE)
and 1.30 g/t (UNDERGROUND SULPHIDE). Pit constrained resources are reported within an optimized pit shell; unde rground resources are reported within
continuous and contiguous shapes which lie adjacent to and below the ultimate open pit shell and interpreted to be recoverabl e utilizing standard
underground mining methods.
The mineral resource estimate has an effective date of August 17, 2020. The mineral resource estimate is based on a long term gold price of US$ 1,500 per
ounce and economic cut-off grades of 0.30 g/t Au (OXIDE PIT CONSTRAINED), 0.60 g/t (TRANSITION AND SULPHIDE - PIT CONSTRAINED) and 1.30 g/t (SULPHIDE
- UNDERGROUND). Pit constrained resources are reported within an optimized pit shell; underground resources are reported withi n continuous and
contiguous shapes which lie adjacent to and below the ultimate open pit shell and interpreted to be r ecoverable utilizing standard underground mining
methods.
The estimate assumes the following metallurgical recoveries that are based on completed test work to date: Oxide 90%, Transition 50%, and Sulphide 84%. The
estimate assumes the following costs: Mini ng (Pit) US$ 2.50/tonne, Mining (Underground) US$ 30.00 Oxide Processing (Heap Leach) US$7.00 / t, Transition
Processing (Heap Leach) US$ 7.00/t, Sulphide Processing US$ 18.00/t ((Leach) and G&A US$ 5.00/t. The pit constrained resource is reported within an optimized
pit shell that assumed a maximum slope angle of 45 degrees. Open pit mining recovery was assumed to be 100%. Open pit dilutio n was assumed to be
0%.Underground mining recovery was assumed to be 100%. Underground dilution was assumed to be 0%.
Micon has not identified any legal, political, environmental, or other risks that could materially affect the potential development of the mineral resource
estimate.
The mineral resource estimates are classified according to the CIM Standards which defin e a Mineral Resource as “a concentration or occurrence of solid
material of economic interest in or on the earth's crust in such form, grade or quality and quantity that there are reasonabl e prospects for eventual economic
extraction. The location, quantity, grade or quality, continuity and other characteristics of a mineral resource are known, estimated or interpreted from specific
geological evidence and knowledge including sampling. Mineral resources are sub-divided, in order of increasing geological confidence, into inferred, indicated
and measured categories. An inferred mineral resource has a lower level of confidence than an indicated mineral resource. An indicated mineral resource has
a higher level of confidence than an inferred mineral resource but has a lower level of confidence than a measured mineral resource."
The CIM Standards define an inferred mineral resource as: "that part of a mineral resource for which quantity and grade or qu ality are estimated on the basis
of limited geological evide nce and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An in ferred
mineral resource has a lower level of confidence than that applying to an indicated mineral resource. It is reasonably expec ted that the majority of inferred
mineral resources could be upgraded to indicated mineral resources with continued exploration."
All procedures, methodology and key assumptions supporting this mineral resource estimate are included in a NI43 -101F1 Technical Report titled “UPDATED
MINERAL RESOURCE ESTIMATE FOR THE CANDELONES PROJECT NEITA CONCESSION DOMINICAN REPUBLIC” which is available at www.sedar.com and on the
Company’s website. The reader is reminded that mineral resources are not mineral reserves a nd therefore do not have demonstrated economic viability.

Surface Infrastructure and Indirect Costs
The mining and processing infrastructure will be located at the Candelones site . Site power is
assumed to be supplied by generators under contract. The mine site is accessible by an International
Highway. No off -site infrastructure is expected to be required. Process Water is available in the
immediate area. Surface water management includes ditches, ponds and pumping stations.
Indirect costs including owner’s costs, engineering, procurement and construction management,
temporary facilities for construction and other related items are estimated at US$ 5.18 million. An
additional US$4.76 million (pre-production) has been budgeted as contingency for specific direct and
indirect costs.
Royalties
A 5.0% net smelter return (“NSR”) royalty on all metals produced from the Candelones Project has
been applied in the PEA. This royalty is pay able to the Government of the Dominican Republic and
forms a minimum tax. The royalty payments are credited against the 27% tax on Net Income.
Environment and Closure
The Candelones Project is located almost entirely on land owned by the Dominican Government. The
project requires the submittal of an Environmental and Social Impact Assessment (“ESIA”) . The
Company will engage the Government through the Ministerio de Medio Ambiente y Recursos
Naturales to develop the framework for the ESIA over the coming months. Environmental baseline
data collection has been initiated and all collected baseline data will inform the ESIA, which will
commence once the framework is finalized. Community consultations have started and will
accelerate over the rest of this year.
In addition to ESIA approval, the project will require permits and authorizations prior to construction
and operation of the mine. Requests for these approvals will be submitted following the E SIA
approval.
A closure plan for the Candelones project will be developed in consultation with the Government and
the local communities as part of the ESIA. Closure costs are estimated at US$3.4 million. The objective
of site closure is to return the site to a fully satisfactory state that includes eliminating all unacceptable
health hazards and ensuring public safety, eliminating the production and spread of contaminants
that could damage the environment and in returning the site to an environmentally sound condition
without the need for maintenance or continuous monitoring.
Stakeholder Engagement
The Candelones Project is located south of the town of Restaura ćion in the northwes tern Dajabon
Province of the Dominican Republic, within a border area that has been designated for preferential
development by the government of the Dominican Republic. Unigold has been proactive in
community engagement for the past twenty years. Project consultations were initiated in 2020 and
will accelerate in 2021. Numerous stakeholders have expressed an interest in learning about the
project. Surveys conducted by Unigold in 2020 allowed members of the community to voice concerns
Unigold Inc. Press Release: PR2021-06 April 26, 2021 Page: 7
about water quality, land disturbance, blasting operations, dust control and impacts to wildlife.
Unigold is committed to addressing concerns and continuing the dialogue with potentially affected
stakeholders through the detailed engineering and environmental assessment process.
The local community has expressed strong support for the proje ct. The main interest in the project
has a focus on employment and entrepreneurial opportunities . In 2020 more than 80 community
members worked at the Company’s projects in the Candelones area.
