    Silica, gold and rare earths exploration: pit design and schedule notes for planners

    Silica, gold and rare earths exploration: pit design and schedule notes for planners

    First reported on Australian Mining

    30 Second Briefing

    Australian explorers are advancing silica sand, gold and rare earths projects, with silica gaining attention as a feedstock for solar glass and high‑purity industrial applications. Activity is concentrating in Western Australia and Queensland, where juniors are drilling shallow, laterally extensive sand deposits and following up high‑grade gold intercepts near existing processing hubs. For geotechs and mine planners, the focus on near‑surface, free‑digging sand bodies and brownfield gold step‑outs points to relatively low strip ratios, simpler pit designs and faster development timelines than deeper hard‑rock projects.

    Technical Brief

    • For similar near-surface sand and regolith deposits, geotechnical models can often rely on dense drilling with limited core.

    Our Take

    Silica sand appears in far fewer of our 888 keyword-matched pieces than gold, signalling that Australian silica projects are still a niche but emerging segment compared with the more mature gold exploration space.

    With Australia dominating many of the 530 Mining stories in our coverage, additional rare earths exploration there tends to be read against policy settings on critical minerals, which can materially affect permitting timelines and offtake leverage for new projects.

    The presence of A2Z AI alongside commodities like silica sand and rare earths aligns with a small cluster of AI- and artificial-intelligence-tagged items in our database, suggesting exploration workflows for these materials are starting to integrate data-driven targeting rather than relying solely on conventional field campaigns.

    Meta and Sprott in nuclear revival: demand signals and risks for uranium projects

    Meta has signed nuclear power deals with Vistra, TerraPower and Oklo for up to 6.6 GW of capacity by 2035 to run its US data centres and the Prometheus AI supercluster in Ohio, adding to a 20‑year, 1.12 GW offtake from Constellation’s Clinton plant. In parallel, the Sprott Physical Uranium Trust has bought 300,000 lb of U₃O₈ in a week, lifting holdings to about 75.2 million lb worth US$6.17 billion, as spot prices hover around US$82/lb. For miners and project developers, this combination of long‑term nuclear PPAs and aggressive physical uranium accumulation signals firmer demand visibility despite persistent SMR cost and schedule risk.

    Derrick Experience Center: fine screening test gains and risks for plant engineers

    Derrick Corporation has opened its Derrick Experience Center (DEX Center) in January 2026 to mark its 75th anniversary, creating a dedicated test hub for advanced fine screening technology. The “first-of-its-kind” facility is designed for current and prospective customers to run full-scale trials on Derrick high-frequency screens and Polyweb® urethane panels under controlled conditions, rather than relying solely on on-site pilots. The centre is intended to shorten test campaigns, de-risk screen selection, and optimise cut size and throughput for fine coal, iron ore, base metals and industrial minerals circuits.

    University of Arizona mine waste project: key processing insights for engineers

    A $3.6 million Arbor-funded University of Arizona Tailings Center project, led by mining engineer Dr Isabel Barton, is evaluating whether 17.5 billion tons of historic copper tailings in Arizona—growing by ~100 million tonnes per year—can be reprocessed to recover critical minerals and reduce environmental risk. The team is combining statewide and UAV-based remote sensing, industry tailings datasets, drilling and surface sampling, mineralogical characterisation and techno-economic analysis using magnetic separation and basic leaching. Early work has identified unexpected mineral occurrences, including arsenic, zinc and possibly tungsten, which could justify flowsheet changes to keep these elements out of future tailings.
