GT Gold Corp. (TSX-V:GTT)
(the
“Company” or “GT Gold”) is pleased to provide notice
that a National Instrument 43-101 technical report (“NI 43-101” or
“Technical Report”) has been filed with Canadian securities
regulators to support the maiden mineral resource estimate
(“Mineral Resource”) for the Saddle North project (“Saddle North”)
on the Company’s 100%-owned Tatogga property, located in
northwestern British Columbia, Canada.
Paul Harbidge, President and CEO stated, “We are
delighted to file the technical report in support of the previously
disclosed maiden mineral resources for Saddle North, which marks
another significant step for the company. An updated sensitivity
analysis supports the presence of the continuous higher-grade core
of mineralization, which has the potential to drive the value for
our next key milestone, the Preliminary Economic Study”.
Highlights:
- The large mineral resource comprises an
Indicated resource containing 1.81 Blb copper and 3.47 Moz gold and
an Inferred resource containing 2.98 Blb copper and 5.46 Moz
gold.
- Continuous higher-grade central core of
mineralization within the deposit offers optionality and
flexibility to be studied as part of the Preliminary Economic
Assessment (“PEA”) to drive value.
- Good metallurgical results point to a simple
process, with conventional flowsheet and clean concentrate.
- Excellent local infrastructure with a main
highway crossing the property, a hydro powerline within easy access
and a nearby deep-water port at Stewart, British
Columbia.
- The topography of the property is highly favorable for
the potential future development of the project both in
terms of open pit and underground operations.
- Highly prospective exploration with the Saddle
North deposit remaining open along strike and at depth. Saddle
South provides additional project potential, it is only three
kilometres from Saddle North and consists of a precious metal rich
sheeted vein system. There are additional untested targets in
proximity to Saddle North and South. At the new Quash Pass target,
where there are two multi-kilometre anomalous trends, phase 1
diamond drilling is underway.
The Preliminary Economic Assessment is underway
and will examine mining options, which are made possible by the
size, grade and mineral distribution in the deposit. These will
include:
- A starter pit that accesses the easily mineable surface ±150m
which is situated at the top of a gently-sloping valley
- An underground operation, accessing the higher-grade core
through a decline and which uses lower cost bulk mining
methods
The Technical Report, dated effective August 20,
2020, is titled " NI 43-101 Technical Report on the Saddle North
Copper-Gold Project" and is available under the Company's profile
on SEDAR (www.sedar.com).The Technical Report was authored by
Richard Flynn, P.Geo., Principal, Next Mine Consulting Ltd., who is
a qualified person within the meaning of NI 43-101, is independent
of the Company and has reviewed and approved the disclosure
regarding the resource estimate for GT Gold disclosed herein.
The Mineral Resource and Technical Report for
the Saddle North gold-rich copper porphyry system is founded on the
geological model completed in Q1 2020 (see press release dated
April 28, 2020).

Notes to Table 1:
- Results are reported in-situ and diluted (underground resource)
and are considered to have reasonable prospects for eventual
economic extraction, but not unplanned dilution. Dilution in the
underground estimate is approx. 5 Mt Indicated and 27 Mt Inferred
avg. $12/t NSR.
- As Independence is defined under NI 43-101, the Qualified
Person is Mr. Richard Flynn, P.Geo. of Next Mine Consulting Ltd.
(NMC), who is independent of GT Mining and has reviewed, validated,
and takes responsibility for the Mineral Resource Estimates.
- The block model was regularized to 15 m x 15 m x 15 m whole
blocks using mineralization.
- The effective date of the Mineral Resource estimate is July 6,
2020.
- The number of metric tonnes are rounded to the nearest million,
gold ounces are rounded to the nearest thousand and silver ounces
were rounded to the nearest ten thousand. Any discrepancies in the
totals are due to rounding.
- Pit constrained Mineral Resources are reported in relation to a
conceptual pit shell above an NSR cut-off of $9.00/t.
- Underground Mineral Resources assume block-cave mining method
that does not allow selectivity. A bulk mining shape based on an
NSR cut-off of $16.00/t was used to constrain the estimate and all
blocks within the cave shape were tabulated irrespective of
grade.
- Block tonnage was estimated from volumes using an average
density per lithological unit. Specific gravity had a range of 2.75
to 2.86.
- All copper, gold and silver assays have been capped prior to
being composited at 15m, breaking at lithology and alteration
contacts.
- NSR calculation is based on a price of USD 3.25 per pound of
copper, USD 1,500 per ounce of gold, USD 18 per ounce silver, and
copper recoveries of 88%, gold recoveries of 67% and silver
recoveries of 58%. Foreign Exchange assumption was $0.76
C$/US$.
- Net Smelter Return (“NSR”) ($/t) = (Cu% x 2204.62 lb/t x Cu
Recovery x payable% x Cu CAD Price) + (Au g/t ÷ 31.1035 g/ounce x
Au Recovery x Au CAD Price x payable%) + (Ag g/t ÷ 31.1035 g/ounce
x Ag Recovery x Ag CAD Price x payable%).
- Copper Equivalent in % (CuEq) = Cu% + Au g/t * 0.53 + Ag g/t *
0.005.
- All values in Canadian dollars unless otherwise stated.
- Differences may occur in totals due to rounding.
- Transition-Sulphide boundary determined from visual logging
(weak oxidation in transition material limited to fracture plane
surfaces).
- The CIM Definition Standards (May 10, 2014) were followed for
classification of Mineral Resource.

Data Verification
The data described above is supported by using
industry standard QA/QC procedures consisting of the insertion of
certified standards and blanks into the sample stream and utilizing
certified independent analytical laboratories for all assays.
Historical QA/QC data and methodology on the project were reviewed
and are summarized in the NI 43-101 Technical Report. The
qualified person detected minor but no significant QA/QC issues
during review of the data.
All geological data used in the mineral resource
estimate was reviewed and verified by Richard Flynn, P.Geo, of Next
Mine Consulting Ltd. who made two site visits in June of 2020. Site
visits included:
- review of GT Gold’s logging and sampling techniques
- viewing of core from seven Saddle North boreholes
- confirmation of borehole collar field locations
Qualified Person
In accordance with National Instrument 43-101
Standards of Disclosure for Mineral Projects, Michael Skead,
FAusIMM, Vice President Projects, is the Qualified Person for the
Company and has validated and approved the technical and scientific
content of this news release.
Risk Factors
GT Gold is aware this project is subject to the
same types of risks that large base metal projects experience at an
early stage of development in northern British Columbia. The
Company has engaged experienced management and specialized
consultants to identify, manage and mitigate those risks. However,
the types of risks will change as the project evolves and more
information becomes available.
About GT Gold
GT Gold is focused on exploring for base and
precious metals in the geologically prolific terrain of British
Columbia’s renowned Golden Triangle. The Company’s flagship asset
is the wholly-owned, 46,827 hectare Tatogga property, located near
Iskut, British Columbia, upon which it made two significant
discoveries in 2017 and 2018 at its Saddle prospect: a precious
metal rich vein system at Saddle South and a gold-rich copper
porphyry system at Saddle North.
