Accelerate Resources Limited (ASX:AX8) is pleased to report positive results from baseline metallurgical test work on a bulk surface sample (~150kg) from the Braeside West prospect within the Woodie Woodie North Manganese Project in Western Australia (Figure 1).
- Initial surface sample results indicate Direct Shipping Ore (DSO) potential with an average lump and fine grade of 41.4% Mn and 13.6% Fe
- Heavy Media Separation (HMS) results from a 150kg composite sample at Target 42 (Braeside West Prospect) indicate manganese can be upgraded to a 43.4% Mn premium concentrate
- Further metallurgical test work is underway to target a battery-grade product
- An RC drilling program will test the near surface high-grade potential of the area

Managing Director Yaxi Zhan commented,
“This latest test work supports the potential of the Woodie Woodie North Project area to produce high-grade manganese concentrate products. These are currently in high demand for the steel and battery markets. We will use this study to initiate a more detailed test work program as we look forward to reporting the results from our first major drilling program.”
Multiple surface grab samples were collected over an area of approximately 4 hectares and composited into a single bulk sample representing outcropping surface manganese (Figure 2).
Outcropping manganese occurs as “pods” up to tens of metres in area on surface (Photo 1 and Photo 2).
The results are very encouraging, demonstrating a DSO (Direct Ship Ore) Lump quality product with grades up to 40.9% Mn and 13.8% Fe.
The tests were preliminary in nature and form the baseline for product optimisation in future metallurgical programs.

Metallurgical Test Work Summary
Accelerate engaged specialist metallurgical laboratory, Nagrom Laboratories (Perth), to conduct preliminary manganese test work on the surface bulk sample. The test work programs explored conventional low-cost heavy media separation (HMS) techniques, including dense media separation (DMS) using cyclones for fines and Ericsson Cone (EC) for lump.
