THETA GOLD MINES LIMITED | ANNUAL REPORT 2024
CHAIRMANS
LETTER
Dear Fellow Shareholders,
On behalf of the Board of Directors, I am pleased
to present the 2024 Annual Report for Theta Gold
Mines Limited (ASX: TGM). The Company has made
significant progress over the last twelve months.
The company is advancing the TGME Underground
project on the ground. The team is on-site completing
execution documentation and final design for the gold
plant build process.
RM Process and Eco Elementum have been
appointed to complete the final designs for the plant,
tailings, and water management. They assist Theta
and Power China in compliance with local regulations.
RM Process, a South African-based process
engineering company, will assist with the Final
designs of the TGME Gold Plant and will form part of
the execution team with Theta and Power China.
The Eco Elementum group of companies provides
an array of independent, multidisciplinary, and
integrated environmental science, engineering, and
construction services. Eco Elementum will assist with
the final designs of water management systems and
assist the design team in environmental and legal
compliance with the Water Use Licence
During the year, the company has also examined
tailings and rock dumps with high gold prices. With
the 174,000 oz of gold sitting on the surface, the
company has been examining ways to accelerate the
path to gold production.
Theta selected Power China subsidiary as the
preferred EPC partner to build stage one of its
TGME Gold Plant and TSF facilities estimated at
US$30 million1.
In July 2022, the Company completed a FS for the
first four mines Beta, CDM, Frankfort and Rietfontein
(TGME Underground Gold Project). The Base Case life
of mine (LOM) plan will comprise a 12.9-year mining
operation starting in 2024 to deliver production
of 1.24 million ounces of contained gold. Peak
production is expected to be over 100,000 ounces
per year. By adding the fourth mine Rietfontein to
the mining schedule, there has been a significant
scale-up from the April 2021 pre-feasibility study
with a production rate of just above 60,000 ounces
per annum.
Underground mining will deliver higher-grade ore to
the gold plant with a much smaller environmental
footprint that’s well supported by the local
community and key stakeholders, with access to
a larger resource base of 4.5 million ounces of
underground mineral resources.
Environment, Social and Governance (ESG) The
Company’s focus remains to work closely with our
stakeholders and communities to strengthen the
existing relationships and, to establish a mutually
beneficial relationship that is healthy and sustainable.
The TGME Stakeholder Forum continues to gain good
momentum with open and honest communications
between all parties.
Theta is also developing an Ecological Compensation
Programme. Independent Environmental Scientist
has been requested to provide us with a proposal
to develop a guideline for the execution of the
compensation programme that was developed in
2022. This plan will include recommendations on the
Implementation Agreement.
Moving forward into the 2025 financial year, the
company will target finalising funding arrangements
and begin construction of the TGME Gold Project.
As part of this due diligence process, the Power China
team has been onsite drilling and collecting samples
for metallurgical test work with the Theta team. The
test work has assisted in refining the final plant design
and evaluating the tailings at the TGME mine site.
We appreciate the continued support from our
shareholders, and we welcome new shareholders
to the share register. The Company looks forward
to continuing to progress project development and
deliver good news for shareholders in 2024.
The TGME Underground Feasibility Study (FS) was
completed in July 2022, at $1642 USD gold price.
Now the gold price is trading at all time high levels
above 2,600+ USD at the time of this report.
Thank you for your continued support.

REVIEW OF
OPERATIONS
OVERVIEW
The TGME Project (Phase 1) incorporates the
first four mines. In April 2021 Theta declared a
maiden underground Mining Reserve of 419,000 oz
@ 5.49 g/t Gold, along with the first Maiden
Underground Pre-Feasibility Study. The Mining
Reserve were based on only 16% of the 4.5 Moz
underground gold resource and incorporated only
three mines across the project area.
Theta Gold Mines Limited (“the Company” or
“Theta Gold” or “TGM”) is a gold exploration
and development company that holds a range of
prospective gold assets through its 74%-owned
subsidiary Transvaal Gold Mining Estate Ltd (TGME)
in a world-renowned South African gold mining
region. The Company’s shares are dual listed on the
Australian Securities Exchange (ASX: TGM).
The Company’s TGME Underground Gold Mine
Project (“The Project” or “TGME Project”) phase
one consists of four existing mines, Beta, Frankfort,
CDM and the Rietfontein mine. The Project is
located next to the historical gold mining town of
Pilgrim’s Rest, in the Mpumalanga Province, some
370km northeast of Johannesburg or 95km north of
Nelspruit (the Provincial Capital City) and includes
more than 43 historical mines identified across the
vast prospective gold field of 620 square kilometres
(62,000 hectares).
The Company delivered its very first definitive
Feasibility Study (FS) in July 2022 which presents a
clear pathway to production via the re-development
of TGME’s gold assets and is currently focused on
the holistic strategy to deliver long term organic
growth, with initial development focusing on the
permitting of six mines to target a production profile
of 160,000 ounces Au per annum.

DRILLING AND SAMPLING
ON THE TGME GOLD MINE
TAILINGS DAM
The Company announced that the Power China
team has been onsite drilling and collecting
samples for metallurgical test work. The test work
will assist in refining plant design and evaluating
the tailings at the TGME mine site. The tailings
dams contain 140,000 oz gold and will be tested
for metallurgical gold recovery. SGS South
Africa (Pty) (Assay Laboratory) Ltd, engaged
by TGM’s preferred Engineering Procurement
and Construction (“EPC”) partner Power China
subsidiary, (Yellow River Co., Pty (“YRC”) to
complete a drilling and sampling program at
various tailing dams around the Company’s
TGME gold plant for metallurgical test work.
The program was completed with a total of
407 meters drilled, 273.5 meters drilled into
the TGME main and four (4) Blyde tailings and
133.5 meters into the Glynn’s tailings. Theta
Gold currently records 141,000 ounces of gold
JORC Resources across multiple tailings dams
around the gold plant. In total, 174,000 gold
ounces sit on the surface surrounding the TGME
gold plant, including 140,000 ounces indicated
as a resource in various tailings dams around the
TGME plant area.

THETA’S TGME GOLD PROJECT DEFINITIVE FEASIBILITY
STUDY (FS)
The FS13 for the TGME Project was delivered on 27 July 2022, confirming Theta Gold’s potential to be a
significant near-term, high-margin, low-cost gold production project with tremendous opportunities for
future growth. Based on the FS results, the Project will provide robust financial returns from a long-life large
underground mining operation for a modest capital investment given the scale of operations envisaged.
The Project LOM will initially comprise a 12.9-year mining operation starting in, 202414 calendar year and
delivering LOM production of 1.24 Moz of contained gold. The estimated peak development Capital Expenditure
(“Capex”) is A$103 million, with the Project forecast to generate a pre-tax NPV10% of A$432 million and pretax internal Rate of Return (IRR) of 65% at a forecast average gold price of A$2,189 per ounce. Based on these
metrics, the Project has a projected capital payback period of 31 months.
The FS paves the way for a Final Investment Decision (‘FID’) by the Theta Gold Board in respect to funding
negotiations and on-going discussions with financiers with respect to full/partial debt and equity funding options.
Theta Gold has appointed a debt funding advisor to manage this important process and will provide updates in
due course.

The TGME Project targets to restart historical underground gold mines located in a historically prolific gold mining
region in the Mpumalanga Province of South Africa. The Project Areas are centred in the town of Pilgrims Rest,
some 370 km due northeast of Johannesburg, and vast majority of the tenements were under TGME’s ownership
since the late 1800s.
The Project targets the Beta (including the Beta North, Beta Central and Beta South sections), Rietfontein,
Frankfort and Clewer-Dukes Hill-Morgenzon (“CDM”) mines. A significant amount of gold resources remain
underground which were not mined historically due to technological limitations or limiting ore characteristics.
Beta is scheduled as the first operation to commence production, followed by Rietfontein, and finally CDM and
Frankfort simultaneously. In comparison to CDM and Frankfort, Beta and Rietfontein are higher-grade mines.
A gold plant, which acts as the central processing plant for all the historical operations, is situated in close
proximity with a maximum distance to operations of approximately 40km. A new facility will be established on this
footprint to treat all the ore from the surrounding operations.
Two scheduling strategies have been investigated in the FS. The Base Case considers a LOM plan targeting
the total Mineral Resources (Measured, Indicated and Inferred). The Ore Reserve Case considers a LOM plan
targeting only Measured and Indicated Mineral Resources.
This FS demonstrates the ability to achieve optimised cash flows by scheduling production from the operations.
The mine designs and associated costs per operational element feed into a combined operations financial model.
The Ore Reserve Case supports the declaration of compliant JORC Code 2012 Ore Reserves.
TGME UNDERGROUND GOLD MINE DEVELOPMENT
As part of the preparation for the installation of the first phase new gold plant, TGME had appointed the services
of Jet Demolition to remove the redundant plant equipment. The process started in the second week of January
2022. Specialised equipment was utilised for demolition, after which it was reduced in size and made ready for
transport to scrap merchants. The project to remove the old plant is now complete15.
Processing consultants Met63 was contracted to do a detailed design and costing of a processing plant designed
for a feed capacity of 45,000 tons per month which is equivalent to 67 tons per hour at 92% availability. A flow
schematic is shown in Figure 12.

The FS has been split into three phases, allowing for various processing scenarios aligned with the mining
development program. The design of each phase is based on a stand-alone processing facility aligned with the
mining plan of the ore body.
