TORONTO, ONTARIO - Cerrado Gold Inc. (TSX.V: CERT) (OTCQX: CRDOF) (“Cerrado” or the
“Company”) is pleased to announce that it has filed the technical report of the independent
Feasibility Study (“FS”) as prepared by DRA Global Limited (“DRA”) in accordance with National
Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43 -101") on its 100% owned
Monte do Carmo gold project located in Tocantins State, Brazil. The technical report, shows a
positive adjustment to the economic parameters presented in the November 7, 2023 press release
outlining results of the Feasibility Study. The full technical report has now been filed on SEDAR+ as
of December 15, 2023.
The positive adjustment reflects the results of work undertaken by DRA and GE21 during the
completion of the FS to include:

• Recently completed additional metallurgical optimization test work on variability samples
have demonstrated improved flotation concentrate leach efficiencies and reduced cyanide
consumption rates. Projections indicate that over the life of the mine, an additional 0.4%
recovery improvement or 3,7koz of gold is anticipated to be recovered, accompanied by
a 2.7% reduction in process operating costs.
• In addition, the receipt of supplier s quote for larger size haulage equipment as well as the
optimization of both the open pit and underground mining fleets, resulted in CAPEX savings
of $5. 2M in direct costs and $2. 8M in sustaining costs. This has led to a resulting OPEX
reduction of $20 per ounce.
As a result, the After Tax NPV 5% increased to $390 million from $369 million and the IRR increased
to 34% from 32%. Other financial information pertaining to project capital and operating costs have
also been updated in accordance with the changes above.
Mark Brennan, CEO and Chairman, stated: “We are extremely pleased that the ongoing work by
DRA has resulted in a modest improvement in what were already robust Feasibility Study results.
The Feasibility Study demonstrates that the Monte do Carmo project is poised to be an extremely
robust project with low capital and operating costs that will generate cash flows well above its
weight as a 100,000 ounce producer of gold while providing an approximate 2:1 ratio of NPV over
Capex.”
He continued, “With the feasibility study work now completed, we plan to move to the next stage
of bringing the project to development. We anticipate we will receive the construction license in
Q1 2024 and hope to complete our Export Credit Agency backed financing in Q3 2024.”
The FS outlines a robust project, with low capital costs and low operating costs generating significant
Free Cash Flow over a 9-year mine life. The FS is focused on the principal Serra Alta deposit and the
smaller satellite deposit of Gogo Do Onca and provides a scalable base of production from which to
build on future potential exploration success.
Monte do Carmo is expected to commence production at a rate of 1.92 Mtpa from the open pit for
total production of 712,989 ounces. In Year 4, simultaneous underground development will be
initiated, and is expected to contribute an additional 143,916 ounces over five years of operation.
Two open pit operating scenarios were analyzed for cost estimation purposes. The first scenario
involved a traditional owner -operated model, while the second scenario explored a contractor -
operated model. Over the 9 -year life of the mine, it was found that the owner -operated option
produced a higher NPV and other advantages, although resulting in a reduction in IRR. FS selected
the owner-operated option for both the Open Pit and Underground Operations.
Ore is processed at the plant using conventional concentration and cyanide leaching of gold bearing
concentrates. Tailings will be disposed of using a combination of best in practice dry stack , co -
stacking and in-pit filling techniques.
The Company remains on track to receive the construction permit by the end of th is year and is
progressing Project Financing with an aim to make a fully financed construction decision in Q2 2024.

Monte do Carmo Project Overview
The Monte do Carmo Gold Project is located in the state of Tocantins, Brazil; 2 km east of the town
of Monte do Carmo, 40 km from Porto Nacional and 100 km from Palmas, the capital of Tocantins
state. The Serra Alta deposit has been the main focus of exploration and development at the Monte
do Carmo Project. Cerrado has conducted preliminary drilling on several analogue satellite deposits
however the Company has been mostly focused on infill drilling at Serra Alta to support the
Feasibility Study. The Project benefits from convenient access to essential infrastructure including
paved roads, energy, 69 kV electric al power line, water supply, and an international airport, and is
well supported by the local community.

Geology, Mineralization and Drilling
The regional geology of the Monte do Carmo area is characterized by multiple volcanic-sedimentary
sequences with a number of intrusive suites spanning from the Lower to Upper Proterozoic eras, as
well as younger Paleozoic sedimentary successions. The Serra Alta deposit itself is hosted by a cupola
of the Monte do Carmo Granite (Paleoproterozoic Ipueiras Intrusive Suite) within the
Neoproterozoic Araguaia Belt of Tocantins state, located within the broader Trans -Brazilian
Lineament.
At the deposit scale, the Monte do Carmo Granite, along with other later felsic and mafic-ultramafic
layered intrusions, intrudes felsic volcanic rocks of the Santa Rosa Suite with an overlying (faulted
contact) discontinuous quartzite remnant, possibly of the Upper Proterozoic Monte do Carmo
Formation. The entire package is in turn unconformably overlain by flat -lying Paleozoic (Meso-Neo
Devonian) ferruginous sediments of the Pimenteiras Formation, subject to relatively intense
subaerial weathering (i.e., laterite and saprolite development).
The Serra Alta deposit is interpreted as an intrusion -related gold system, with mineralization
associated with hydrothermally altered and locally vein ed granitic rocks. Abundant mineralized
shoots are clearly controlled by varying densities of vein and veinlet swarms that are weakly
enriched in sulphides (pyrite, galena, sphalerite and chalcopyrite). The deposit currently comprises
8 main zones that span approximately 2 km of strike length (oriented 190 –195o) with an overall
width of ~600 m, and dip moderat ely to steeply (55 –75o) to the west -northwest with a vertical
extent on the order of 200 m. In general, individual mineralized lenses (i.e., shoots) range from
approximately 5 m to greater than 30 m in width.

Sheeted vein sets mostly follow the overall deposit trend; however, the presence of multiple
mineralized vein orientations indicates a more complex system that evolved over several
mineralization and deformation events, as evidenced by the structural history of the area. There are
two main northeast-trending (~N30oE) faults that flank the mineralization at Serra Alta, with a series
of smaller east -west (± 30 o) faults that delimit the deposit into discrete structural blocks; as such,
each zone was modelled and esti mated individually to respect these constraining features. The
lateral extent of the sheeted vein swarms is wider towards the intrusive contact between the main
granitic host rocks and overlying felsic volcanics; this intrusive contact acts as a cap throughout much
of the deposit.
Modern exploration at the Monte do Carmo Project began in 1985 by Verena Mineração Ltda (VML).
A total of 8,629 m of historical drilling in 75 holes has since been completed by several companies,
including VML (eventually Monte Sinai Mineração), Paranapanema and Kinross; Rio Tinto also drilled
an additional 3,894 m in 53 reverse circulation holes. This work focused on a variety of regional
targets in addition to Serra Alta. Recent exploration drilling by Cerrado includes a total of 108,987 m
completed in 439 holes up to the database cut-off date of December 31, 2022. The current Mineral
Resource Estimate (MRE) includes a total of 12,690 composite sample intervals in 338 holes that
intersect the interpreted mineralized domains used for estimation. Historical drilling has been
vetted for quality and consistency purposes; only holes that meet a stringent multi-criteria standard
were maintained in the database for use in the MRE.
In terms of expansion potential, while the Serra Alta deposit has generally been well -tested,
prospective areas of interest to extend mineralization remain both to the east and north, as well as
to depth . Additionally, the Monte do Carmo region in general remains highly prospective for
exploration potential with multiple high -priority targets already identified within the Cerrado land
package.
Data Verification
DRA performed data verification a nd validation procedures on the drilling database prior to
modelling and estimation. DRA reviewed the geological, drilling and analytical data, including the
implemented Quality Assurance / Quality Control (“QA/QC”) measures, used to support Mineral
Resources. Additionally, the QP of Geology and Resources completed a visit to the Project site in
order to review overall site geology, drill core, core shack facilities, sample storage and security, as
well as to conduct interviews with key site personnel. It i s the opinion of the QP that the provided
geological database is of sufficient quality for use in the estimation and classification of Mineral
Resources, according to CIM guidelines and industry best practices.
Mineral Resource Estimate
The MRE was established using data from boreholes drilled and sampled up to December 31, 2022.
The in-pit resource estimate for the Serra Alta deposit includes Measured and Indicated Resources
of 15,304 kt @ 1.65 g/t Au for 812 koz, and Inferred Resources of 345 kt @ 1.36 g/t Au for 15 koz;
the underground portion includes Measured and Indicated Resources of 3,054 kt @ 2.03 g/t Au for
199 koz, and Inferred Resources of 708 kt @ 2.24 g/t Au for 51 koz. The resource estimate has been
prepared using a marginal cut-off grade of 0.2 6 g/t Au for the in -pit resources ; underground
resources include low-grade blocks falling within underground reporting shapes to reflect realistic
mining logistics. Both the open -pit and underground resources are reported using a gold price of

US$1,850. Additional details on mining and processing modifying factors are provided in the
footnotes for the table below.

Notes:
1. The Mineral Resource Estimate has been estimated using the Canadian Institute of Mining,
Metallurgy and Petroleum (CIM) Definitions Standards for Mineral Resource and Mineral
Reserve in accordance with National Instrument 43-101 – Standards of Disclosure for
Mineral Projects. Mineral Resources which are not Mineral Reserves, do not have
demonstrated economic viability.
2. Inferred Mineral Resources are exclusive of the Measured and Indicated Resources.
3. In-pit Resources are constrained by a Pseudoflow optimized pit shell using HxGn MinePlantm
software.
4. Pit shell was developed using a 50-degree pit slope, gold sales price of US$1,850/oz, mining
costs of US$2.60/t, stockpile rehandling costs of US$0.60/t, processing costs of US$10.14/t,
tailings costs of US$1.45/t, G&A costs of US$2.43/t, process recovery 96.5%, refining costs of
US$12.00/oz, transportation costs of US$10.74/oz, discount rate of 5%, and assumed
production rate of 1.920 Mtpa.
5. In-pit estimates are reported in-situ, at a marginal cut-off grade of 0.26 g/t Au.
6. Underground mining stope optimization was performed using Deswik tm software.
7. Stope shapes were developed using a gold sales price of US$1,850/oz, mining costs of
US$24.18/t, processing costs of US$10.14/t, tailings costs of US$1.45, G&A costs of
US$2.43/t, process recovery of 95.3%, refining costs of U$12.00/oz, transportation costs of
US$10.74/oz, and assumed production rate of 1,500 t/d.
8. Underground resources were estimated using a cut-off grade of 0.69 g/t Au; however, the
reported in-situ figures include low-grade blocks estimated within underground reporting
shapes.
9. Resource estimations were interpolated using Inverse Distance Weighting (IDW3); Similarly,
variable densities were interpolated using IDW2.
10. The effective date of the Mineral Resource Estimate is October 31, 2023.
11. Figures have been rounded to an appropriate level of precision for the reporting of Mineral
Resources. As a result, totals may not compute exactly as shown.

(Section 8810420N) is also provided below, highlighting the proximity of estimated blocks outside
the pit shell to the east , which represent the underground portion of the reported Mineral
Resources.
Mineral Reserve Estimate
The Mineral Reserve Estimate was established using the Mineral Resource Estimate with the
effective date of October 31 , 2023. The total mineral reserve estimate of the Serra Alta deposit
includes Proven Reserves of 2 Mt @ 1.68 g/t Au for 109,000 oz (in-situ) and Probable Reserves of
14.8 Mt @ 1.66 g/t Au for 787,000 oz (in-situ). The reserve estimate has been prepared using a cut-
off grade of 0.2 8 g/t Au for the in -pit reserves, and 0.8 g/t Au for the underground reserves. Both
the open-pit and underground reserves are reported using an assumed gold sales price of US$1,700.
Additional details on mining and processing factors are provided in the footnotes for the t ables
below.
The open pit design includes 14,344 kt of Proven and Probable Mineral Reserves at a grade of
1.62 g/t Au. To access these reserves, 112.5 Mt of waste rock must be mined resulting in a stripping
ratio of 7.8 to 1.
The underground design includes 2,451 kt of Proven and Probable Mineral Reserves at a grade of
1.90 g/t Au. To access these reserves, 800 m twin ramps will be developed from a mine portal
located in the Central Pit . A total of 19,400 m of lateral development in ore and waste will be
required during the underground operation. The mining method selected for Monte do Carmo is
long hole transverse open stoping with cemented rockfill with minimum stope width of 3 m and
maximum height of 20 m. The table below presents the mineral reserves for the underground mine.
