The Board of Tivan Limited (ASX: TVN) ("Tivan" or the "Company") is very pleased to announce that Major Michael Stone (Retd) has joined the Company's Technical Advisory Group ("TAG" or the "Group").

The Timor Awakening Program is a joint Australian and Timor-Leste initiative focused on veteran rehabilitation, mental health support, solidarity and community development. He is also a Co-founder and Board member of Veterans Care Association Incorporated Australia.

Mr Stone has worked extensively at senior levels within Timor-Leste, including advisory roles to the Office of the President and the Timor-Leste Defence Force, as well as participation in national forums, commissions and international engagements. He has developed deep and enduring networks across government, security institutions, traditional leadership and local communities, underpinned by long-term in-country experience and cultural understanding.

Mr Stone served for 25 years as an officer in the Australian Army, holding a range of command, advisory and training roles, including assignments in Timor-Leste supporting military training, institutional development and international taskforce operations. His experience includes contributions to security sector reform, crisis response and coordination, including peacekeeping deployments in 1999-2002 and key roles during the 2006–2008 Timor-Leste crisis.

Mr Stone has significant experience in stakeholder engagement, mediation and conflict resolution, and has led and contributed to a range of community-based and policy initiatives in Timor-Leste, including programs focused on reconciliation, development and social impact.

He holds a Bachelor of Arts (Management, Geography) from the University of New South Wales at the Australian Defence Force Academy, together with qualifications in management and personnel administration.

Mr Stone is fluent in Tetun and has basic Portuguese capability. His honours and awards include the Presidential Medal of Merit from the President of Timor-Leste, the Medalha Solidariedade de Timor-Leste and a Chief of Defence Force Commendation for exemplary operational service.

Timor-Leste Project Portfolio

This appointment comes as Tivan continues to progress its Timor-Leste project portfolio, including the Turiscai Project awarded in March 2025, and the Baucau and Ossu projects acquired in November 2025. The Projects combined cover an area of ~633km2 and provide Tivan with a strong commercial foundation to develop the mineral resources sector in Timor-Leste. Tivan has established an in-country presence, including a local office and team supporting corporate, geological and logistics functions, and is focused on developing local capability across its operations.

The Turiscai Project is located approximately 40km south of Timor-Leste's capital of Dili and comprises seven Exploration and Evaluation Licenses spanning an area of 344km². The Baucau and Ossu Projects are located 123km east of the capital of Timor-Leste, Dili, along established transport corridors.

Timor-Leste, situated in the southern Outer Banda Arc, is a geologically complex region where tectonic interactions between the Australian and Eurasian Plates result in significant mineral-rich formations. Despite its promising geological characteristics, Timor-Leste remains significantly underexplored with very limited historical exploration undertaken. The geological setting hosts some of the world's most significant copper-gold deposits including Grasberg (Central Papua, Indonesia), Ok Tedi (Papua New Guinea), Wafi-Golpu (Papua New Guinea) and Pangora (formerly referred to as Bougainville, Papua New Guinea).
