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.

EIS Grant for Minnie Springs Copper Porphyry Drilling
- Augustus Minerals has been granted a co-funded drilling grant of up to $110,000 for 2 x 700m deep diamond drill holes under the WA Government’s Exploration Incentive Scheme (EIS) for the Minnie Springs prospect.
- The deeper diamond drill program is designed to test and to provide a 550m deep, 1km wide geological/geochemical/structural cross-section through the large 3km long by 1km wide copper moly porphyry system, linking the Mo mineralised leucogranite to the extensive Cu in soil anomaly to the northeast.
- Previous RC drilling at Minnie Springs intersected mineralisation, geology and alteration halo consistent with the zoning of a large porphyry copper / moly system.
Andrew Ford, GM Exploration
“The Company is pleased to receive an EIS grant to complete deeper drilling at the Minnie Springs Copper Molybdenum Project. The resultant data will enable mapping of the lithology and alteration to a depth of 550m and potentially intersect, or provide vectors to, higher grade Mo-Cu mineralisation using a Mo-Cu porphyry geological model”.
Minnie Springs
Minnie Springs hosts porphyry related copper molybdenum mineralisation previously drilled and defined by Catalyst Metals. A molybdenum Exploration target has been defined for the historicdrillingareacomprisedofbetween12-84Mtasoutlinedbelow (Table 1 and Figure 1, 2.)1.
Table 1. Exploration target size estimate for Minnie Springs Molybdenum depositNote: Based on ~300 ppm cut-off at 100% recovery.
The potential quantity and grade of the exploration target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resources, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
The planned diamond drilling will complement the recently completed 3,200m RC drilling program that infilled around hole MSRC012 (18m @ 0.37% Cu and 9.7 g/t Ag from 94m downhole, and 16m @ 0.38% Cu and 19.4g/t Ag from 121m downhole2) and tested the northern half of the 2km long copper-in soil anomaly. Assays from this program are expected to become available over the next month.
The limited exploration in the region, highlighted by 95% of the Ti-Tree project having no previous exploration, demonstrates the prospectivity of this underexplored mineral province.

Quarterly Activity Report 31 March 2024
Figure 1. Fiery Creek Copper Prospect/Yataga Granodiorite summarizing rock (brown diamonds) and termite mound sample results (black crosses)
Continuing with its primary exploration focus on the Georgetown project in the latter half of 2023, EMU received assay results during the quarter from its second, in field reconnaissance work. The geochemical sampling programme covered the Fiery Creek high grade copper vein swarm and the Snake Creek prospects with significant element results returned from the Fiery Creek Copper (elevated Cu-Au-Ag-Bi-In-Pb-Sb-Te) and Snake Creek (elevated Pb-Ag-Au-Sb).
Whilst the survey was cut short due to inclement weather, EMU was encouraged by the significant success reflected in the assays results. The results from mineralogical studies confirmed EMU’s interpretation of an indicative, scale Copper-Porphyry system at the Fiery Creek prospect and was a highlight of the survey with new information building on the scale and potential of the prospect1.
Assay results returned included:
- Fiery Creek rock assay results up to 23.5% Cu, 0.27ppm Au, 460ppm Ag, 1.9% Bi, 89ppm In, 2.7% Pb, 667ppm Sb, 1470ppm Zn2.
- evidence of strong potential for the presence of critical and strategic minerals (Cu, Bi, In), with precious and base metals.
- evidence of alteration mineralogy, mineralisation geochemistry and areal extent of the Fiery Creek quartz-Cu-Bi vein swarm strongly suggesting a previously unrecognised subjacent porphyry Cu-Mo system.
- Yataga Granitoid Complex termite mound and coincident rock chip sampling returned several anomalous polymetallic zones for follow up.
- Snake Creek Prospect assays returned 0.20ppm Au, 390ppm Ag, 22.4% Pb, 464ppm Sb1.
Significant results were returned from the Fiery Creek Copper prospect with elevated Cu-Au- Ag-Bi-In-Pb-Sb-Te and from the Snake Creek prospect with elevated Pb-Ag-Au-Sb.
The elevated pathfinder element results and a macro-petrology assessment3 of rock samples completed by Mr Nigel Maund, Consulting Economic Geologist, from the previously unexplored Fiery Creek Prospect, point to the discovery of a porphyry copper system.
The sampling program assessed a number of high-priority prospects within the Georgetown Project tenements utilising termite mound and outcrop rock chip geochemistry. A total of 46 rock chip and 489 termite mound samples were collected across eight prospects.
