Gold Terra Announces Significant Increase of 64% for the Inferred Mineral Resource to 1,207,000
Ounces at its Yellowknife City Gold Project
March 16, 2021, Vancouver, B.C. – Gold Terra Resource Corp. (TSX -V: YGT; Frankfurt: TX0; OTC QX:
YGTFF) (“Gold Terra” or the “Company” ) is pleased to announce an updated mineral resource estimate
on its Yellowknife City Gold project (the “YCG Project”), located 12 kilometres from the City of Yellowknife,
NWT. The classification of the mineral resource estimate was completed in accordance with the Canadian
Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards incorporated by reference in
National Instrument 43-101 (“NI 43-101”). This updated mineral resource estimate includes the Sam Otto,
Crestaurum, Barney and Mispickel gold deposits (see Figure 1) previously reported in the initial November
2019 mineral resource estimate prepared in accordance with NI 43 -101 and includes assay results fr om
the 2020 drill program on the Sam Otto (9,622 metres) and Crestaurum (7,648 metres) deposits.
The 1,207,000 ounce inferred mineral resource consists of an:
▪ Open pit constrained inferred mineral resource of 21. 8 million tonnes averaging 1.25 g/t for
876,000 ounces of contained gold, and an
▪ Underground inferred mineral resource of 2.55 million tonnes averaging 4.04 g/t for 331,000
ounces of contained gold.

President and CEO David Suda stated, “We are pleased to announce the significantly expanded inferred
mineral resource for the YCG Project, which demonstrates the growth potential of this project to all
stakeholders. With a 1.2 million ounce inferred mineral resource, the mineralized system is open for
further expansion in most directions. Currently, our focus is drilling the unexplored potential of the
Campbell Shear structure which produced more than five million ounces of high-grade gold at the Con
Mine. The Campbell Shear drilling, which commenced in late 2020, has the potential to demonstrate
that our district scale YCG Project may host multiple deposits.”

The 2021 updated mineral resources and its upside potential
The 2021 inferred mineral resource estimate illustrates the growing value of the Yellowknife camp and
has opened-up several exploration opportunities to increase mineral resources on the Northbelt property.
The Yellowknife camp was developed along the Campbell Shear, the main structure in the belt and host
to the largest gold plumbing system of the area on which both the Giant (8 million ounces produced) and
Con Mines (6.1 million ounces produced) were developed. Similar to most Archean gold camps in Canada
and in the world, numerous gold deposits within the YCG Project may re-establish Yellowknife as a premier
mining camp in close proximity to the City of Yellowknife where all the infrastructure is already in place,
making the development of these deposits much easier. Specific targets with the potential to increase
mineral resources include:
• The untested depth extension on both the Sam Otto Main and the Sam Otto South deposits.
Both Sam Otto deposits are open to the North and at depth and it is recommended to follow up
with a drill program at depth below the current deposit outline or below the 250 metre vertical
depth.
• Selective closer spaced drilling at the Crestaurum deposit can potentially increase mineral
resources below the 300 metre depth. SGS Geological Services constrained the Crestaurum
deposit to above 300 vertical met res as 2020 drilling below this depth and down to 500 vertical
metres that successfully intersected the gold structure was deemed too wide ly spaced to be
included in the inferred mineral resource.
• In addition, 2020 drilling on the Crestaurum deposit revealed an untested three-kilometre strike
length of this gold bearing structure to the south of the current resource, possibly extending to
the Ranney Hill high-grade showings on surface and effectively tripling the strike length of this
gold bearing structure.
• A review of the structural controls on the Mispickel and Barney deposits during the 2021
mineral resource estimation revealed potential for increasing these h igher grade zones both
along the plunge of the known high-grade zones, and for discovery of new high-grade lodes over
a potential three-kilometre mineralized structure at Mispickel.
Estimation Methods
The mineral resource estimate for 2021 includes the four gold deposits previously reported in the initial
mineral resource estimate prepared in accordance with NI 43 -101 in November 2019: Sam Otto,
LEGAL*52589836.1

Crestaurum, Barney and Mispickel, which are all within a three-kilometre radius. The initial mineral
resource estimate incorporated the results from the 463 drill holes totaling 90,751 met res used in the
2019 mineral resource estimate, and for this update an additional 59 holes totaling 17, 540 metres are
incorporated from drilling completed in 2020 on the Crestaurum and Sam Otto deposits. In general, the
drilling is variably spaced reflecting different mineralization styles and ranges from 25 to 100 metres apart.
The mineral resource estimate was prepared by Dr. Allan Armitage, P.Geo., from SGS Geological Services
(“SGS”). SGS used Geovia Gems software to construct mineralized wireframes for each zone and then
interpolated tonnage and grade into block models constr ained by the mineralized wireframes and used
inverse distance squared (ID 2) or inverse distance cubed (ID 3) interpolation. Appropriate interpolation
parameters were generated for each deposit based on the mineralization style and geometry.
The pit shells were created using Whittle pit optimization software and applying the following
optimization parameters: US$1,500 gold price; US$2.20/tonne for mining cost; U S$16.00/tonne for
processing and G&A costs; 90% metallurgical recovery; 5% dilution (external); 5% mining loss; and 60° pit
slopes (the deposits occur in areas of extensive outcrop with negligible overburden).
A review by SGS engineers of the size, geometr y and continuity of mineralization was conducted to
determine underground mineablility of the deposits. On the Sam Otto deposit it was concluded that bulk
underground mining below the pit shells was possible, and a cut-off grade of 1.4 g/t Au is used to define
underground inferred mineral resources on this deposit using an underground mining cost of
US$44.00/tonne and US$16.00/tonne processing and G&A costs. Similarly, bulk underground mining at
the Barney deposit uses a cut -off grade of 2.0 g/t Au and a mi ning cost of US$68/tonne with
US$16.00/tonne processing and G&A costs. Crestaurum is considered a high -grade selective mining
deposit and a 2.5 g/t cut -off grade is used with a mining cost of US$79.00/tonne with US$16.00/tonne
processing and G&A costs.
The mineral resource estimate s are summarized in the following table. A supporting technical report
prepared in accordance with NI 43 -101 will be filed on SEDAR at www.sedar.com within 45 days of this
release.

(1) The classification of the current mineral resource estimate into an inferred mineral resource is
consistent with current 2014 CIM Definition Standards - For Mineral Resources and Mineral
Reserves
(2) All figures are rounded to reflect the relative accuracy of the estimate.
(3) All mineral resources are presented undiluted and in situ and are considered to have reasonable
prospects for eventual economic extraction.
(4) Mineral resources which are not mineral reserves do not have demonstrated economic viability.
An inferred mineral resource has a lower level of confidence than that applying to a measured
mineral resource and an indicated mineral resource. The quantity and grade of reported inferred
mineral resources in this estimation are uncertain in nature and there has been insufficient
exploration to define these inferred mineral resources as a measured mineral resource or an
indicated mineral resource and it is uncertain if further exploration will result in upgrading the
inferred mineral resource to a measured mineral resource or an indicated mineral resource.
(5) It is envisioned that parts of the Sam Otto/Dave’s Pond, Mispickel and Crestaurum deposits may
be mined using open pit mining methods. Open pit mineral resources are reported at a cut -off
grade of 0.4 g/t Au within a conceptual pit shell.
(6) It is envisioned that parts of the Sam Otto/Dave’s Pond and Barney deposits may be mined using
lower cost underground bulk mining methods whereas parts of the Crestaurum deposit may be
mined by underground selective narrow vein methods. A selected cut -off grade of 1.4 g/t Au is
used to determine the undergr ound mineral resource for the Sam Otto/Dave’s Pond deposit, 2.0
g/t Au for the Barney deposit (assuming it can be accessed underground from the Crestaurum
deposit), and 2.5 g/t for the Crestaurum Deposit.
(7) High-grade capping was done on 1 m composite data. Capping values of 55 g/t Au were applied
to Crestaurum and 60 g/t Au for Mispickel.
(8) Specific gravity values were determined based on physical specific gravity test work from each
deposit: Crestaurum at 2.85; Barney at 3.00; Sam Otto and Mispickel at 2.80.
(9) Cut-off grades are based on a gold price of US$1,500 per ounce, a gold recovery of 90%, processing
cost of US$16.00 per tonne milled, and variable mining costs including US$2.00 for open pit and
US$44.00 to US$79.00 for underground.
(10) The results from the pi t optimization are used solely for the purpose of testing the “reasonable
prospects for economic extraction” by an open pit and do not represent an attempt to estimate
mineral reserves. There are no mineral reserves on the Property. The results are used as a guide to
assist in the preparation of a mineral resource statement and to select an appropriate resource
reporting cut-off grade.
(11) The estimate of mineral resources may be materially affected by environmental, permitting, legal,
title, taxation, socio-political, marketing, or other relevant issues.
Significant increases in the in situ mineral inventory from the 2019 mineral resource estimates was
achieved by the 2020 drilling at Sam Otto and Crestaurum, which increased the strike and dip of both
these deposits.
Increases in reported total inferred mineral resources in 2021 also reflects the change in gold price from
$1,300/oz Au in the 2019 resource estimate to $1,500/oz Au in the 2021 mineral resource estimate. Other
LEGAL*52589836.1
5 / 7
economic parameters for generating cut -off grades remained the same as in 2019. The increase in gold
price resulted in a drop in open pit cut-off grade from 0.50 g/t Au in 2019 to 0.40 g/t Au in 2021.
Additionally, changes in underground mining methods and higher gold price resulted in a lowering of
underground mining cut-off grades from 3.0 g/t Au in the 2019 mineral resource estimate to 2.5, 2.0 and
1.4 g/t Au for Crestaurum, Barney and Sam Otto respectively.
It should be noted that for the Crestaurum deposit, the reported inferred mineral resource estimate was
only extended to 300m vertical depth. Gold Terra drilled several holes below this depth in 2020 that
intersected the Crestaurum minera lized structure, but it was decided by SGS that the spacing between
these deep holes, and their distance from the shallower drilling on Crestaurum precluded their inclusion
in the 2021 mineral resource estimate.
Technical Information and Quality Control Procedures
The technical information contained in this news release has been verified, reviewed and approved by Dr.
Allan Armitage, P.Geo. from SGS, who is an independent Qualified Person under NI 43 -101. The
information contained in this news release was also verified, reviewed and approved by Joe Campbell, P.
Geo., Chief Operating Officer for Gold Terra and a Qualified Person under NI 43-101.
Gold Terra ’s dri lling programs are monitored through the implementation of a quality assurance and
quality control (QA/QC) program. The drill core (NQ size) is logged and sample intervals for assay are
selected by Gold Terra’s geologists. In general, the sampling intervals vary from half a metre to one metre
in length depending on the geology and mineralization observed. The drill core samples are cut by
diamond saw at Gold Terra 's core facilities in Yellowknife. Half of the core sample is left in the core box
and stored in a dedicated core storage facility in Yellowknife. The other half-core samples are transported
in securely sealed bags by Gold Terra personnel to ALS Limited (“ALS”) preparation laboratory in
Yellowknife. After sample preparation, samples are shipped to ALS Vancouver facility for gold and a
complete digestion four acid ICP analysis for 33 elements. Gold assays of >3 g/t are re -assayed on a 30
gram split by fire assay with a gravimetric finish. ALS is a certified and accredited laboratory service
operating to ISO 17025 standards. ALS routinel y inserts certified gold standards, blanks and pulp
duplicates, and results of all QC samples are reported. Gold Terra inserts certified standards and blanks
into the sample stream as a check on laboratory QC.
In addition to traditional assay methods, Gold Terra also carries out a variety of spectrometry tests on
selected core and rock samples to determine the associated mineral characterization and the gold
deportment within the mineralized zones.
About Gold Terra’s Yellowknife City Gold Project
The YCG Project encompasses 800 sq. km of contiguous land immediately north, south and east of the
City of Yellowknife in the Northwest Territories. Through a series of acquisitions, Gold Terra controls one
of the six major high-grade gold camps in Canada. Being within 10 kilometres of the City of Yellowknife,
the YCG is close to vital infrastructure, including all -season roads, air transportation, service providers,
hydro-electric power and skilled tradespeople.
The YCG Project lies on the prolific Yellowknife greenstone belt, cove ring nearly 70 kilometres of strike
length along the main mineralized shear system that host the former-producing high-grade Con and Giant
gold mines. The Company's exploration programs have successfully identified significant zones of gold
mineralization and multiple targets that remain to be tested which reinforces the Company's objective of
re-establishing Yellowknife as one of the premier gold mining districts in Canada.

CAUTIONARY NOTE TO UNITED STATES INVESTORS CONCERNING ESTIMATES OF MEASURED,
INDICATED AND INFERRED RESOURCES
The Company prepares its disclosure in accordance with the requirements of securities laws in effect
in Canada, which differ from the requirements of U.S. securities laws. Terms relating to Mineral Resources
in this news release are defined in accordance with NI 43 -101 under the guidelines set out in CIM
Standards.
The United States Securities and Exchange Commission (the "SEC") has adopted amendments
effective February 25, 2019 (the "SEC M odernization Rules") to its disclosure rules to modernize the
mineral property disclosure requirements for issuers whose securities are registered with the SEC under
the United States Securities Exchange Act of 1934. The SEC Modernization Rules have replac ed SEC
Industry Guide 7, which will be rescinded following a transition period and after the required compliance
date of the SEC Modernization Rules.
As a result of the adoption of the SEC Modernization Rules, the SEC will now recognize estimates of
"Measured Mineral Resources", "Indicated Mineral Resources" and "Inferred Mineral Resources", which
are defined in substantially similar terms to the corresponding CIM Standards. In addition, the SEC has
amended its definitions of "Proven Mineral Reserves" and "Probable Mineral Reserves" to be substantially
similar to the corresponding CIM Standards.
United States investors are cautioned that while the foregoing terms are "substantially similar" to
corresponding definitions under the CIM Standards, there are differences in the definitions under the SEC
Modernization Rules and the CIM Standards. Accordingly, there is no assurance any Mineral Resources
that the Company may report as "Measured Mineral Resources", "Indicated Mineral Resources" and
"Inferred Mineral Resources" under NI 43 -101 would be the same had the Company prepared the
resource estimates under the standards adopted under the SEC Modernization Rules.
United States investors are also cautioned that while the SEC will now recognize "Measured Mineral
Resources", "Indicated Mineral Resources" and "Inferred Mineral Resources", investors should not to
assume that any part or all of the mineral deposits in these categories would ever be converted into a
higher category of Mineral Resources or into Mineral Reserves. Mineralization described by these terms
has a great amount of uncertainty as to their existence, and great uncertainty as to their economic and
legal feasibility. Accordingly, investors are cautioned not to assume that any "Measured Mineral
Resources", "Indicated Mineral Resources", or "Inferred Mineral Resources" that the Company reports
are or will be economically or legally mineable.
Further, "Inferred Resources" have a great amount of uncertainty as to their existence and as to whether
they can be mined legally or economically. Therefore, United States investors are also cautioned not to
assume that all or any part of the Inferred Resources exist. In accordance with Canadian securities laws,
estimates of "Inferred Mineral Resources" cannot form the basis of feasibility or other economic studies,
except in limited circumstances where permitted under NI 43-101.
In addition, disclosure of "contained ounces" is permitted disclosure under Canadian regulations;
however, the SEC has historically only permitted issuers to report mineralization as in place tonnage and
grade without reference to unit measures.
