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.

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.

La Mancha Resource Capital has sold a 3.5% stake in Endeavour Mining via a C$71.25-per-share bought deal worth about C$605 million, cutting its holding from roughly 15% to 11% while retaining board representation through Naguib Sawiris. Endeavour, now valued around C$17.5 billion after a 191% share price rise in 12 months, produces in the mid- to high-900,000-oz.-per-year range from West African assets including Houndé (Burkina Faso) and Ity and Agbaou (Côte d’Ivoire). The move comes as Burkina Faso has nationalised Endeavour’s former Boungou and Wahgnion mines, paying about $80 million and asserting full state control.
