Further Bulk Sampling and Metallurgical Test Work Underway at Blesberg

Marula Mining PLC (AQSE: MARU A2X: MAR) an African focused mining and development company, is pleased to provide the following update in respect to additional metallurgical test work and bulk sampling at the Blesberg Lithium and Tantalum Mine in South Africa ("Blesberg" or the "Project") that are being conducted by its South African operating subsidiary, Southern African Lithium and Tantalum (Pty) Ltd ("SALT").

The Company's technical team and executive management collected an approximately 30-tonne bulk sample from the Blesberg mine site. The sample is currently being prepared for a comprehensive metallurgical test work aimed at evaluating the chemical and physical properties of the material and optimising future processing strategies that are aimed at maximising recoveries of all key strategic and critical minerals, as well as high-value industrial mineral by-products that have been identified.

The bulk sample is to be crushed and sorted into -80mm and -25mm size fractions to simulate the proposed processing plant feed conditions and to enable comparative analysis across particle sizes. The material will then undergo a series of testing to further assess the physical and chemical characterisation of pegmatitic host rock, liberation and particle size distribution analysis, magnetic susceptibility and leachability testing and optical sorting and flotation response analysis.

In addition, optical sorting, wet high intensity magnetic separation, heavy liquid separation, gravity separation and dense medium separation testing is to be undertaken.

The results of these work programmes will provide insights into the metallurgical behavior of the Blesberg ore and support the development of an optimised and scalable first phase processing flowsheet that will feed into the Company's planned lithium acid leaching plant to produce an intermediate lithium product for use in the manufacture of lithium batteries and other high value lithium products.

As announced on 23 June 2025, testing indicated the presence of high-value by-product industrial minerals within the lithium-bearing pegmatites at Blesberg, based on results from metallurgical test work. The ore consists primarily of microcline and plagioclase feldspar, making up between 60% and 80% of the material.

Assay results included:

·    Al₂O₃ grades of approximately 18%

·    Combined CaO and MgO grades of less than 1%

·    Combined Na₂O, K₂O, Li₂O, and Rb₂O grades exceeding 11%

·    Combined Al₂O₃, K₂O, CaO, and MgO grades of over 30%.

The Company is continuing to advance its applications for a Mining Right at Blesberg and has satisfied two of the three key conditions with Environmental Authorisation for the Mining Right and submission of an updated Social Labour Plan having already been progressed. The Company's Broad-Based Black Economic Empowerment ("B-BBEE") structure for SALT, is currently being completed in compliance with Section 100(2)(a) of the MPRDA and the requirements of Mining Charter III.

Further updates on the metallurgical test work and B-BBEE structure will be provided in due course.
