Last week centered on moving mine data faster and making it more reliable—from near real-time pit feeds to migrating PI tags into modern data lakes. Several members traded hard-won lessons on OT networking hiccups (including a stubborn “phantom” IP issue) and practical field fixes like vent bag leaks and spinning bolts. Water remained front and center with dewatering control and turbidity monitoring for compliance. On the workforce side, threads weighed remote robot operation versus on-site tech roles, plus a healthy stream of job posts and a career pivot discussion into reclamation and water work.
