MetalsGrove Mining (ASX:MGA) reports a recently completed airborne magnetic survey has confirmed a large magnetic corridor of interest at its Woodie Woodie North Manganese Project in Western Australia.
The airborne geophysical survey has highlighted multiple structures coincident with the source area, and with surface geochemistry.
The result of the survey, coupled with the pre-existing geochemistry data, provides a suite of compelling targets as MetalsGrove advances towards a maiden drilling program later this year.
Historical surface sampling has highlighted clear manganese potential with grades up to 52% Mn and Co 250ppm.
A number of both discrete and elongated magnetic anomalies of potential Mn exploration targets have been highlighted by this recent detailed aeromagnetic surveying, elongated anomalies are curvilinear in nature with clear structural breaks and disruptions within the broader corridor.
Of particular interest to MetalsGrove is the eastern magnetic trend which has clear manganese mineralisation present at its southern extremity.
Two intrusive type magnetic anomalies were also highlighted.
Preliminary data has been interpreted and final data will be processed and interpreted shortly, and this will include modelling if required to assist confirmation of source spatial location and geometry.
The survey included an area with previously defined Mn geochemical anomalies.
A total of 24 anomalies were picked and ranked from enhanced imagery. From these, 12 priority main initial targets were delineated.
Of these targets, 6 stand out as ‘extensive’ and are associated with the broad conductor identified from the electromagnetic and radiometric regional AEM survey.
MetalsGrove reports follow-up ground investigation is required to further rank target areas and trends and then most likely additional geophysical surveys such as passive or active AEM or ground IP will be required to refine highest priority prospects for drill targeting.
MetalsGrove Managing Director Sean Sivasamy said the company is delighted with the outcomes from the survey, which has significantly improved its technical understanding of the Woodie Woodie North Project and highlighted several compelling drill targets.
“We are moving quickly to finalise all necessary approvals as we target our maiden drilling campaign at Woodie Woodie North later this year.

“MetalsGrove is also rapidly advancing exploration across its other priority tenements in Western Australia and the Northern Territory, namely Upper Coondina and Arunta, in what is shaping up as a very busy finish to the calendar year.”.
During August 2022, Thomson Airborne Surveys Pty Ltd completed a detailed airborne magnetic and radiometric survey to test MetalsGrove’s Woodie Woodie North Manganese Project.
The targets identified in the AEM survey cover about 8km of the ‘Magnetic Signature’ interpreted to lie along the eastern and western complex in its Rippon Valley target area.
MetalsGrove also notes the geochemical trend and magnetic anomalism coincide at Rippon Valley.
The Woodie Woodie North Manganese Project, which comprises a single granted exploration licence, is located approximately 100km east of Marble Bar in the eastern Pilbara region.
The tenement covers an area of approximately 13,740ha.
Nearby mines include the Woodie Woodie manganese mine owned by Consolidated Minerals (ASX:CSM), which is some 50km to the south-east, and its well-connected ‘world-class’ infrastructure.
MetalsGrove Mining is an Australian based exploration and development company, focused on the exploration and development of its portfolio of high-quality lithium, rare earth, copper-gold, manganese and base metal projects in Western Australia and the Northern Territory.
MetalsGrove is committed to green metal exploration and development to meet the growing demand from the battery shortage and renewable energy markets in the transition to a decarbonised world.
