Great Divide Mining (ASX: GDM) has reported its first full quarter of steady concentrate output from the Challenger gold project at Adelong in New South Wales, producing 191.3 wet metric tonnes of gold concentrate in the September quarter at an average grade of 43.1 g/t. The update, released on 7 October 2026, matters because it shows a small producer moving from commissioning toward a repeatable run rate while the gold price remains historically elevated.
Quarter by quarter detail
Monthly output was uneven. July delivered 62.1 wmt and August fell to 48.1 wmt because of planned shutdowns, before September rebounded to 81.1 wmt as plant feed rates lifted to between 20 and 24 tonnes per hour. Concentrate grades held in a tight band of 41.5 to 45.4 g/t. Eight shipments totalling 195.8 wmt left the site during the quarter, slightly more than was produced, which drew down opening inventory of 21.2 wmt.
Offtake and pricing exposure
All Challenger concentrate is sold to MRI Trading under a binding offtake that runs from April 2026 to June 2027, with a large share of the contained gold priced against London Bullion Market Association benchmark rates. That structure gives GDM direct exposure to the spot gold price without a hedge book, which helps when prices are strong but leaves cash flow sensitive to any pullback.

What it means for ASX gold investors
For the December quarter, GDM is targeting shipments of about 25 wmt per week at a grade above 40 g/t, subject to maintenance and shutdown needs. Hitting that target would put annualised volumes at the lower end of its earlier 26 to 52 wmt weekly range, so consistency will be the key test. Other priorities include stabilising the plant at nameplate capacity and progressing open cut and underground mine planning. Small producers like this can move sharply on operational news, and one slow month can swing sentiment.
