Zinc Inventories in China Major Markets Fall This Week

Eureka Metals announced plans to commence a 3D induced-polarization survey shortly at its Cabin Lake silver-lead-zinc-gold project in British Columbia, Canada. SJ Geophysics will survey the West, New, Central, East and Bluff mineralized zones. The work follows July fieldwork that collected 622 soil and 96 rock samples. Survey results will be integrated with geological, geochemical and historical information to prioritize drill targets. An initial drilling program remains subject to receipt of the required permit.

Boab Metals updated resources at its Sorby Hills silver-lead project in Western Australia. Resources within the lead and net-smelter-return domains total 50.6 million tonnes, up 7%, grading 3.0% lead, 0.4% zinc and 34 g/t silver. The update covers Bimota, Omega and Norton and excludes recent assays from the 47-hole Phase IX program. On September 28, Boab also announced a binding mining-services heads of agreement with REGROUP Australia Pty Ltd . Site establishment is scheduled for January 15, 2027, with mining services commencing no later than March 1. Execution of the definitive contract is targeted within two weeks of the heads of agreement.

Altoro Metals (ASX: ARO) has reported progress in its maiden 1,400m diamond drilling program at the Guajaraz Zinc-Lead-Silver Project in central Spain. The company has completed three drill holes, with G-03 intersecting brown sphalerite veinlets that confirm zinc sulphide mineralization at depth. The program is designed to evaluate carbonate-hosted replacement-style zinc deposits and explore subparallel structures associated with the historical La Unión mine. While G-01 and G-05 remain in progress, G-05 has already encountered gneissic rock displaying intense hydrothermal alteration and low-grade mineralization. Core samples are undergoing systematic logging, with assay results expected within four to six weeks. Altoro is currently refining its drilling strategy to target high-potential zones while simultaneously progressing an application to extend the site's three-year exploration permit. Once G-01 is finalized, the company plans to redeploy one drill rig to its flagship Novales-Udías Project.
