The Mineral Systems approach attempts to view the spatial and temporal distribution of ore deposits by relating the processes that control the source, transport, and deposition of metals and other commodities to the evolving structure of Earth’s crust and mantle. The change from searching for specific types of mineralisation to understanding aspects of hydrothermal or magmatic architecture at different scales presents new challenges and perspectives for acquiring, processing and interpreting geophysical data. For this TeamWA Workshop we have invited a series of talks by expert geophysicists who address this topic by presenting advances in methods, and case studies. Barry Bourne from Terra Resources presented, “Geophysical Exploration for Gold: Regional to Mine Scale Targeting”. Click here to view the...

Rift Valley Resources Limited (“Rift Valley” or “Company”) (ASX: RVY) is pleased to announce further encouraging assay results from the current drilling programme at its 100% owned Miyabi Gold Project in Tanzania. Initial (composite) assay results have been received from reverse circulation (RC) drilling at Miyabi. Highlights include: Geophysical anomaly “Sid” hits broad zone of high grade gold mineralization MBRC 449 – 18m @ 4.23g/t Au from 87m Including 9m @ 8.01g/t from 96m And 3m @ 1.58g/t from 138m Sid mineralization is contained within a broad zone of 24m @ 3.21g/t Au from 84m Shambani drilling confirms strike extension MBRC 447 – 3m @ 1.71g/t from 15m and 9m @ 0.86g/t from 66m and 6m @5.03 g/t from 81m MBRC 448 – 6m @ 1.45g/t from 138m New Prospecting licence issued over the area containing the current 704,000oz Au resource Drilling continues Click here to view the full ASX...

Highlights Strong Induced Polarisation (IP) anomaly in close proximity to supergene gold mineralisation identified at Contessa. The IP anomaly extends for a distance of 150m, has a target depth of 150m to 200m and lies below and south-east of Lodestar drilling. The anomaly is strongest on the section corresponding with previous ore-grade drill intercepts1, including LNR546 – 15m at 3.1g/t gold from 40m LNR656 – 21m at 3.01g/t gold from 40m and LNR545 – 10m at 1.2g/t gold from 50m An RC program to test the IP anomaly is now a high priority and currently being planned. West Australian gold explorer Lodestar Minerals Limited (ASX:LSR, “Lodestar” or “the Company”) advises that the results of the recently completed detailed aeromagnetic and Induced Polarisation (IP) geophysical surveys at the Contessa gold prospect have now been received and reviewed. Contessa is located on the Company’s 100%-owned Ned’s Creek project, located 170km north of Meekatharra, Western Australia (Figure 1). Lodestar completed a gradient array and pole-dipole IP survey at Contessa to assist with targeting bedrock gold mineralisation beneath the extensive supergene gold mineralisation intersected by aircore drilling. The Contessa gold discovery was made by the Company in 2013. An initial surface sampling program identified a 6km gold and Bi-Mo anomaly overlying granite-greenstone.

Successful radiometric and aeromagnetic surveys reveal priority target areas HIGHLIGHTS Targeting using the recently-acquired, ultra-detailed airborne geophysics completed at the Mt York Lithium-Gold Project in WA. Numerous new pegmatite targets identified from radiometric and aeromagnetic data interpretation. Targets to be field-checked, mapped and sampled over the coming weeks ahead of drilling planned for early next quarter. Results suggest significant future upside potential at Kairos’ Mt York Project. Kairos Minerals Limited (“Kairos” or “Company” ASX: KAI) is pleased to advise that it has received the final results from a targeting exercise using recently acquired airborne geophysical data from its Mt York Lithium-Gold Project, located in the highly prospective Pilgangoora region of WA’s East Pilbara (see Figure 5). As a result of this work, multiple pegmatite targets have been identified throughout Kairos’s tenement package, using ultra-detailed radiometric and aeromagnetic data. These targets highlight the significant potential of the Mt York Project, which abuts the world-class Pilgangoora Lithium Tantalum Project being developed by Pilbara Minerals (ASX: PLS), as well as the Altura Mining (ASX: AJM) and Dakota Minerals (ASX: DKO) lithium projects. The newly identified target areas will be subject to ground-based exploration activities including reconnaissance field evaluation and mapping/rock chip sampling in the coming weeks ahead of drilling planned for early in the September 2016 Quarter.

Australian Mines Limited (“Australian Mines” or “the Company”) is pleased to advise shareholders that the Company’s recently completed reverse circulation (RC) and diamond core drill program has successfully intersected a thick corridor of disseminated iron sulphides (pyrite +/- pyrrhotite) within the targeted dolerite geology at its Dixon gold prospect – part of its joint venture with Riedel Resources (ASX: RIE). Iron sulphides are often intimately associated with gold mineralisation across the Eastern Goldfields of Western Australia, including at KCGM’s Super Pit Gold Mine in Kalgoorlie, which like Australian Mines’ Dixon mineralisation, is similarly hosted within a dolerite unit. Geological logging of the diamond drill core and RC chips from the Company’s latest drill program indicates that this sulphidic corridor at Dixon is at least 120 metres thick and is continuous for more than 400 metres in length.

Numerous new pegmatite targets identified from interpretation of recently acquired radiometric and aeromagnetic data Targets to be field-checked, mapped, and sampled in the upcoming drilling and field programme Results point to potentially significant upside at Dakota’s Lynas Find lithium project. Dakota Minerals Limited (“Dakota”, “DKO”, or “Company”) is pleased to announce the completion of its latest targeting exercise, using recently acquired geophysical data in the highly prospective Pilgangoora region of Western Australia. Multiple pegmatite targets have been identified throughout the Company’s tenement package, using ultra-detailed radiometric and aeromagnetic data. One of the target areas corresponds with anomalous lithium mineralisation identified from previous rock-chipping1 (Figure 2). These targets point to significant future upside potential at Lynas Find, and will be the subject of further exploration efforts by the Company. Please view the full announcement...
