Strategic Appointments and Board Update

Highlights

• Appointment of Mr Victor Bruinsma, a former Principal Metallurgist at Iluka Resources to oversee metallurgical development and identify opportunities to create value from Rosewood product output.

• Appointment of Mr Neil Patten-Williams, a highly experienced mineral sands Marketing Executive, to progress key marketing discussions with potential future customers.

• The Board of Directors is looking to further bolster the level of technical and development experience available to the Company and announce that Mr Donald Stephens has agreed to step down from the Board

PTR Minerals Limited (ASX: PTR ) ( PTR Minerals or the Company ), is pleased to provide an important update regarding two key appointments to assist in the strategic development of the Company.

Investigations in respect of the Rosewood Titanium Project (Rosewood) remain at an early stage with encouraging results to date. Significant work is ongoing to define the parameters of a potential longlife, large scale titanium project.

To progress this work, PTR is pleased to advise on the appointment of Mr Victor Bruinsma and Neil Patten-Williams who have joined the team to drive metallurgical development, marketing, product mix optimisation and interface with potential customers.

Mr Victor Bruinsma

Mr Bruinsma is a qualified chemical engineer and former Principal Metallurgist at Iluka Resources. He has more than 30 years’ experience in plant operations and project development in the titanium minerals industry.

Mr Bruinsma will provide peer review and technical assurance across its metallurgical test work and study programs.

He has extensive experience in ore characterisation and metallurgical test work, process circuit design and optimisation, product quality control, and the commissioning of new processing facilities. Mr Bruinsma held a central technical role within Iluka’s Technology & Rare Earths Group, providing exposure to and involvement across all the company’s operating assets.

Mr Bruinsma will focus on all technical aspects of the project including scope of metallurgical test work and methodologies, flowsheet development and analytical techniques across the Mining Unit, Feed Preparation, Wet Concentration and Mineral Separation Plants.

Mineral Technologies (MT) have recently commenced work on a second 3-tonne bulk sample from Rosewood East. Mr Bruinsma will work closely with the MT team to continue to progress both upstream and downstream processing options with the expectation of generating further processing and product improvements. Key workstreams will include:

• Seeking to improve recovery of additional higher-grade product material which may include other product credits.

• Reviewing opportunities to upgrade the titanium content within each of the product streams identified to date.

• While the Rosewood material is already very low in deleterious elements, seek to identify if further improvements are possible.

• Consider potential titanium processing optimisation pathways including preliminary laboratory-scale assessment of downstream processing options to guide future technical assessment and offtake discussions.

Mr Neil Patten-Williams

Mr Neil Patten-Williams has over 24 years’ experience in marketing mineral sands products to global customers for Kimberley Mineral Sands, Sheffield Resources and Doral Pty Ltd.

His technical background and strong customer relationships will be important in discussions in respect of the application of potential Rosewood products and how they may work to satisfy customer requirements.

He will work closely with the technical team to develop and optimise the product suite from the Rosewood Project.

Board of Directors

The Board of Directors is looking to increase the level of technical and development experience available to the Company. It is actively considering potential appointments and will update the market as appropriate.

Mr Donald Stephens has agreed to step down from the Board of Directors effective 31 May 2026 . The Board thanks Mr Stephens for his valuable contribution, particularly his strong support to the financial operation of the Company.

About PTR Minerals Limited

PTR Minerals Limited (ASX: PTR) is a critical minerals explorer focused on the discovery of world-class deposits in both frontier and mature mineral provinces.

The Company has a major project holding in the northern Gawler Craton in South Australia where recent exploration has uncovered significant concentrations of titanium rich heavy mineral sands (HMS) over large areas at its Muckanippie Project, which remains open and prospective for increased mineralisation.

Mineralogical test work from the Rosewood East area have indicated HMS with up to >95% Valuable Heavy Mineral content, composed primarily of high value titanium minerals. In addition, the coarse-grained nature of the discovery suggests it is likely to be amenable to producing very high recoveries using conventional gravity spiral processing techniques.

The Company also has highly prospective copper, gold and rare earth projects. Its Woomera and Mabel Creek copper-gold projects are located in the world-class Olympic Copper-Gold Province of South Australia. Work has uncovered Iron-Oxide Copper-Gold style alteration/mineralisation and geophysical targeting work has identified several compelling Tier-1 Copper-Gold targets which are drill ready. The Company’s Comet Project is historically noted for its numerous gold occurrences however early stage Greenfields drilling has identified significant Rare Earths hosted in shallow clays over large areas, at 3 Prospect sites.
