Koba Resources (ASX: KOB) has hit thick, high-grade tin mineralisation in its maiden reverse circulation program at the Mt Garnet tin-tungsten project in north Queensland. The headline hole near the historic Gilmore Mine returned 29m at 1.2% tin and 0.36% copper from 111m, including 15m at 2.0% tin and 2m at 6.3% tin. A step-out hole 230m east intersected 5m at 0.58% tin, suggesting mineralisation extends beyond old workings, with a tin-in-soil anomaly traced about 500m along strike. Three initial holes totalling 277m were the first drilling there in over 45 years; Gilmore produced 26,169 tonnes at 7.6% tin from 1906-1922, with intermittent mining until 1980 to 193m depth. The 24-hole, 2,937m program also returned 10m at 0.25% tin at Stannex, plus zinc-silver-indium intervals. Follow-up drilling is planned before year-end, with maiden drilling at Stannary Hills' Kitchener and Jiminy prospects in late October.

ClassOne Technology has received follow-on production orders from two leading photonics manufacturers for multiple Solstice S8 single-wafer wet-processing systems. Equipped with GoldPro electroplating chambers, the systems will support high-volume gold plating of 4-inch and 6-inch Indium Phosphide (InP) wafers used in next-generation optical devices for Artificial Intelligence data centres and other high-bandwidth communications applications. Both customers have adopted Solstice as their global production tool of record for gold plating and anticipate deploying multiple additional systems as InP-based transceiver capacity expands. SMM believes the repeat orders indicate that the 6-inch InP supply chain is progressing from capacity planning to volume-manufacturing infrastructure, supporting
