Highlights:
- MRG Metals Limited reported excellent Pre-Feasibility Metallurgical test work results.
- The results justify the company’s potential to deliver higher-value products.
- As per the Pre-Feasibility level metallurgical Study, Ilmenite-grade improved substantially from the previous value of 46.7% TiO2, which had been based on smaller metallurgical samples, and now stood at 48.4% TiO2.
- The test results confirmed the material's ability to process readily through typical mineral sand methodologies and equipment.
Heavy Mineral Sands (HMS) player MRG Metals Limited (ASX:MRQ) has reported excellent Pre-Feasibility level Metallurgical test work results from the Koko Massava deposit within MRG's Corridor Sands Project. These results indicate the project's potential for delivering higher-value products, including a premium zircon product, with the potential to further refine to a rutile product specification and a HiTi product.
The results further validate the company’s beliefs that the Koko Massava deposits could be the foundation of a multi-decade mine operation at Corridor Sands.

Summary of products:
Along with the above-mentioned exciting results, test work outcomes also significantly enhanced the Ilmenite product's previous grade. As per the PFS, the Ilmenite grade is 48.4% TiO2, which is higher than the previous value of 46.7% TiO2. The previous value was based on smaller metallurgical samples.
However, the company is still working on the Ilmenite grade with plans to further test this Ilmenite product to 50% TiO2. The company is also planning to better understand the nature of Chromium (0.15% Cr2O3) with the help of a Scanning Electron Microscope (SEM) study.

The test work's other key highlights are:
- The sample contained a negligible amount of oversize (+2.0mm) material.
- The heavy metal content stood at 5.6% with +2.85 specific gravity.
- Presence of moderate fines material with 18.0% -45µm grainsize.
- The heavy mineral had a D80 particle size of 257µm, while the sand fraction had a D80 of 513µm.
The test results also confirmed the Koko Massava material's ability to process readily through typical mineral sand process methodologies and equipment. Interestingly, the material carries low-radioactivity contents, enhancing its desirability for blending. The standard mineral sands process included:
