About Great Divide Mining Ltd

Great Divide Mining describes itself as an Australian gold, antimony and critical metals miner, explorer, developer and producer. It holds five projects across 17 tenements, including two in application. Its stated approach is to focus on producing Assets in areas of historical mining with nearby infrastructure, using the Cash Flow from initial projects to support further exploration.

The Challenger Gold Mine is the operation covered in the latest update, and concentrate is sold under an offtake agreement with MRI Trading AG.

September quarter production

The Challenger process plant recorded feed rates of 20 to 24 tonnes per hour during September. The mine produced 191.3 wet metric tonnes (wmt) of gold concentrate over the quarter, at an average grade of 43.1 g/t gold. Monthly output rose from 62.1 wmt in July to 81.1 wmt in September, while August output of 48.1 wmt was affected by planned shutdowns for maintenance, progressive upgrades and operator training.

Reported monthly concentrate grades were 45.4 g/t in July, 41.5 g/t in August and 42.0 g/t in September. Feed rates averaged 19 to 20 tonnes per hour in July and 17 to 19 tonnes per hour in August, so the September rate was the highest of the three months.

Concentrate shipments

Eight concentrate shipments were dispatched during the quarter, including three shipments in each of August and September, up from two per month in the previous quarter. The company shipped 195.8 tonnes of concentrate at an average of 43 g/t between July and September, drawing on 21.2 wmt of opening inventory at 1 July.

December quarter focus areas

For the quarter ending 31 December 2026, Great Divide is targeting shipments of about 25 wet tonnes of concentrate per week with an average gold grade above 40 g/t. The company states that this guidance is based on current operating parameters and equipment capacities and remains subject to maintenance and shutdown requirements.

Other listed priorities are to stabilise Challenger operations at nameplate capacity, increase operating hours and feed grade where possible, raise the regularity and Volume of shipments under the MRI Trading AG offtake agreement, optimise recoveries and concentrate grades, and progress open-cut and underground mine planning.

Sector backdrop

Small gold producers that sell concentrate rather than doré typically rely on offtake partners for treatment and refining, and their realised returns depend on concentrate grade, payability terms and the gold price. Plants at the early stage of operation commonly report variable monthly output while shutdowns, upgrades and crew Training are completed.

Gold producers across Australia also face cost pressures from labour, power and reagents, which can vary between regions.

Risks shareholders should weigh

Monthly production varied during the quarter, with August output the lowest owing to planned shutdowns, and the company’s December quarter guidance is explicitly subject to maintenance and shutdown requirements. Concentrate grades were lower in August and September than in July.

The update does not report costs, sales Revenue or cash balances, so shareholders have no financial figures to assess from this release alone. The company relies on a single offtake counterparty for concentrate sales, and further Capital may be needed for open-cut and underground development. At $0.225 the share price fell 22.41% on 20 October 2026, a reminder of the Volatility that can affect small-cap miners.

What’s next

The December quarter targets are about 25 wet tonnes of concentrate per week above 40 g/t gold, higher shipment frequency under the MRI Trading AG agreement, and continued mine planning at Challenger for both open-cut and underground development.
