Copper World gets its green light, despite a 59% jump in build cost

Construction Timekeeping Software: The Four-Entry Problem A shift entry gets written four times before it reaches an invoice, and the timesheet has to reconcile against three other records. This piece walks through what breaks when those records disagree, so you can see where your hours and your billing drift apart.
The one that matters
Hudbay and Mitsubishi approve the $2.1B Copper World build in Arizona 
They went ahead with one of the largest new open-pit copper mines in the US even though construction costs rose 59%, which tells you how hard majors want domestic copper. With first production targeted for the second half of 2029, the earthmoving and site work comes well before that, so southern Arizona is where the contractor bids are headed.
Around the industry
Thiess lands two five-year contracts in Mongolia The scope includes underground mining services, and five-year terms are the kind of contract-mining work that keeps a fleet and a crew together through a cycle.
Komatsu approves the K-Tec 1237 ADT scraper on its new HM460-6 A 518 hp artic paired with a scraper and backed by the OEM through North American dealers is aimed squarely at mass earthmoving. If you are running scraper spreads on heavy civil jobs, ask your dealer about it.
Serabi cuts its gold outlook about 17% as Coringa permits stall 
The ramp-up was planned, the ounces were there, and the permit was not. In Brazil the same week, a court halted Belo Sun's $300M gold project.
First Quantum's Kansanshi expansion beats design capacity The Zambian operation is targeting 27 million tonnes of ore throughput in 2026 as the new processing facilities lift output. Beating nameplate on an expansion happens less often than it should, so it is worth noticing when it does.
Fenix starts mining at Beebyn Hub The maiden ore reserve is 26.9 million tonnes at 60% Fe, good for more than five years of mine life in WA's Mid West. A modest reserve that is now producing beats a big resource still on paper.
What it adds up to
Copper surplus masks a looming $332B mine shortfall 
BNEF sees enough refined copper until 2027 and a shortage by 2050, because new mines take so long to develop. Read that next to Copper World, Glencore's Coroccohuayco aiming for a 2029 start, and the permit stalls in Brazil, and it is clear the constraint is the time from approval to first ore, not the orebody.
The automation angle
Think big, start small: a practical path to mining autonomy ABB's mining and materials lead argues for getting to autonomy in small, practical steps rather than one big leap. I spent 10 years underground as a mining engineer, and the smallest useful step I know is the shift record: enter it once, correctly, and let the other three copies follow from it.
