Metallica Minerals Limited functions as an Australian entity primarily engaged in the exploration and advancement of mineral assets, now operating as a subsidiary of Diatreme Resources Limited since its delisting from the ASX in August 2024. The company concentrates on high-purity silica sand, alongside interests in copper and gold prospects. Its cornerstone project remains the wholly-owned Cape Flattery Silica Sand Project in Northern Queensland, which covers an extensive exploration tenure and is globally recognized for its superior-quality silica sand, crucial for specialized glass manufacturing, including solar panels. This project underwent an updated Definitive Feasibility Study in late 2023, outlining significant production potential, although development activities were subsequently paused in mid-2024 following the acquisition. Incorporated in 1997, the company maintains its administrative base in Fortitude Valley, Australia.
