Theta Gold Mines Shifts Office Suite Within Barangaroo's International Tower One, Sydney

Theta Gold Mines Relocates Office Suite Within International Tower One, Barangaroo, Effective 1 July 2026

Theta Gold Mines Limited has informed the market that its registered and principal office address changed on 1 July 2026. The company relocated within International Tower One at 100 Barangaroo Avenue, Sydney NSW 2000, moving from Suite 80 to Suite 68 on Level 35, continuing to operate under Servcorp’s serviced office facilities. The telephone number +61 (02) 8046 7584 remains the same, ensuring uninterrupted communication with investors, regulators, and business partners.

This update was approved by Theta Gold Mines Limited’s Chairman, Bill Guy, in compliance with the company’s disclosure obligations. While such administrative changes are routine for listed entities, market participants are reminded to use the new suite number in all official correspondence and regulatory filings. The company’s website, www.thetagoldmines.com, and key contacts—Chairman Bill Guy and Executive Director Richie Yang—remain unchanged.

Sydney Office’s Role in Supporting South African TGME Gold Project Operations

Theta Gold Mines maintains its corporate headquarters in Sydney, Australia, while its primary operations are located in South Africa’s Eastern Transvaal goldfields. The flagship TGME Gold Project lies near the historic mining town of Pilgrim’s Rest in Mpumalanga Province, about 370 kilometres northeast of Johannesburg by road and 95 kilometres north of Nelspruit, the provincial capital. The Sydney office functions as the administrative and corporate governance centre for the ASX-listed company.

This dual-geography structure—Sydney-based corporate oversight of South African gold assets—is common among ASX-listed resource companies. Theta Gold owns 100% of Theta Gold SA (Pty) Ltd, which holds 74% of TGME and Sabie Mines. This ownership structure complies with Black Economic Empowerment (BEE) requirements under South Africa’s Mining Charter, a critical regulatory framework for mining operations in the country.

TGME Gold Project’s 6.1 Million Ounce Resource Supports Development Goals

The TGME Gold Project, Theta Gold’s main asset, contains a substantial gold Resource of 6.1 million ounces, a significant inventory for an ASX-listed developer. The project features near-surface and shallow underground ore bodies, which provide cost advantages compared to deeper underground mining. These factors are important as the company advances toward commercial gold production.

Theta Gold conducted small-scale production at TGME from 2011 to 2015, gaining valuable operational experience. The company is now focused on constructing and financing a new gold processing plant, a crucial step to transition TGME from development to production. Execution of this financing and construction phase is a key near-term milestone for Theta Gold’s strategy.

Revised February 2026 DFS Projects A$689 Million NPV for TGME Mine

On 3 February 2026, Theta Gold Mines released a revised Definitive Feasibility Study (DFS) for the TGME Gold Mine Project. The DFS outlines a 13.1-year mine life, an NPV of A$689 million, and projected free cash flow of A$1.4 billion, based on an average spot gold price of US$2,884 per ounce.

This detailed engineering and economic assessment suggests a strong economic profile for TGME under these assumptions. Investors should note that DFS projections are forward-looking and subject to risks such as gold price volatility, capital cost changes, permitting, and successful project financing. The company did not disclose the capital expenditure required for the processing plant in this update.

Unchanged Phone Number and Servcorp Facilities Ensure Seamless Investor Communication

Despite the suite change, the telephone number +61 (02) 8046 7584 remains active. Theta Gold’s continued use of Servcorp’s serviced office facilities at International Tower One reflects a capital-efficient approach common among ASX-listed resource developers, prioritizing project funding over long-term office leases.

Key management contacts remain as previously disclosed: Chairman Bill Guy ([email protected]) and Executive Director Richie Yang ([email protected]). The company directs investors to www.thetagoldmines.com for further information. These consistent contact details ensure the office move does not disrupt communications with shareholders, analysts, or regulators.

BEE Compliance and Mining Charter Requirements Influence Corporate Structure

Theta Gold’s ownership is structured to comply with South African regulations. The company owns 100% of Theta Gold SA (Pty) Ltd, which holds 74% of TGME and Sabie Mines. This arrangement fulfills Black Economic Empowerment standards mandated by South Africa’s Mining Charter, which governs historically disadvantaged South African ownership in mining.

Compliance with BEE and the Mining Charter is essential for maintaining and advancing mining rights in South Africa, making this structure strategically vital for Theta Gold’s ability to bring TGME into production. Investors familiar with South African mining understand the importance of these regulatory requirements.

Strategic Location Near Pilgrim’s Rest and Regional Infrastructure Supports TGME Development

The TGME Gold Project’s proximity to Pilgrim’s Rest, a historically significant gold mining town, is a strategic asset. The Eastern Transvaal goldfields have a long mining history, with established infrastructure and experienced workforce contributing positively to project economics. The site’s location about 95 kilometres north of Nelspruit provides access to regional logistics and services.

The near-surface and shallow ore bodies contribute to a favorable cost profile, as shallower mining typically requires less capital-intensive infrastructure than deep-level mines. These geological and locational advantages underpin the investment case presented in the revised DFS and ongoing communications. No changes to operational or development strategies have been announced in connection with the office relocation.

Theta Gold’s Focus on Processing Plant Construction and Financing

The company’s strategic priority remains the construction and financing of a new gold processing plant at TGME. This has been central since small-scale production ended in 2015 and is critical to scaling gold output from the resource base. The company did not disclose a timeline, funding amount, or financing structure for the plant in this update.

Given the strong DFS economics—A$689 million NPV and A$1.4 billion projected free cash flow over 13.1 years—investors may anticipate the company pursuing debt financing, equity capital, or strategic partnerships to fund construction. However, no details on capital costs or financing negotiations were provided. The next significant milestone will be announcements regarding construction funding or commencement.

Share Price Impact and Investor Outlook Following Office Move Announcement

The office suite change is unlikely to have a material impact on Theta Gold’s share price or operational outlook. Such administrative updates typically do not affect valuation. Nonetheless, the announcement demonstrates the company’s commitment to ASX disclosure and corporate governance as it advances TGME’s development.

Investors will likely focus on forthcoming news related to TGME’s financing, construction start, permitting, or resource updates. Given the DFS’s positive economics and resource size, progress on construction financing would be a significant development. No specific timeline for future project announcements was provided in this update.
