Native Mineral Resources Logs 340.9oz Gold Smelt as Blackjack Hits 5,160oz Cumulative
Key Takeaways
- NMR's 8 September 2026 smelt produced 340.9oz of doré across two bars (BJM093–094), continuing the production cadence that delivered a record 1,080.5oz refined gold outturn in August 2026.
- Confirmed assay results for the 1 September smelt (BJM091–092) returned 191.99oz gold and 168.05oz silver at a combined 47.89% gold assay, with BJM092 individually hitting 62.44%.
- Cumulative smelt weight at Blackjack has reached 14,296.3oz since Q1 FY26, with total gold outturn of 5,160.7oz — excluding the pending BJM093–094 refinery results.
- Approximately 815kt of material has been moved across Mid Pit (459kt, 14 blasts) and Podosky (356kt, 12 blasts) since April and May 2026, with 12 further blasts scheduled across both pits.
- The Stockholm Tenements JV with Citigold Corporation (ASX: CTO), announced 3 September 2026, gives NMR an exclusive exploration licence over additional Charters Towers ground that could feed the existing Blackjack processing infrastructure.
Blackjack gold production stays on track with 340.9oz September smelt
Native Mineral Resources Holdings Limited (ASX: NMR) completed its latest Blackjack gold smelt on 8 September 2026, producing two doré bars, BJM093 (Elution) and BJM094 (Gravity), with a combined weight of 340.9oz (10.6kg). The result continues the production momentum that delivered a record 1,080.5oz refined gold outturn in August 2026, as announced on 2 September 2026.
Assay results for the previous 1 September 2026 smelt (BJM091–092) have also been confirmed. The two bars returned a combined 191.99oz gold and 168.05oz silver, with a combined gold assay of 47.89%. BJM092 individually returned a gold assay of 62.44%. Official assay and refinery outturn results for BJM093–094 remain pending and will be incorporated into NMR’s September production results once received.

Cumulative doré production tells the full story
Since Q1 FY26, NMR has produced a cumulative smelt weight of 14,296.3oz across its Blackjack operation, with total gold outturn reaching 5,160.7oz (excluding the pending BJM093–094 results). Gold assay percentages have varied across periods — Q3 FY26 returned 14.36% gold assay against Q2 FY26’s 61.34%, while more recent smelts have tracked closer to the 40–50% range.

Mining advance across Mid Pit and Podosky builds ore supply confidence
Approximately 815kt of material has been moved across NMR’s two active pits since mining commenced in April and May 2026, reflecting the scale of operational activity supporting the Blackjack processing plant.
Blackjack Mid Pit — 14 blasts completed, four more scheduled
Mining at Blackjack Mid Pit commenced in April 2026 and has progressed steadily since. 14 blasts have been completed in total, including two during August, with approximately 459kt of material moved over the period. A further four blasts are scheduled under the current mine plan as mining continues through the planned pit sequence.
Podosky — 12 blasts completed, eight more ahead
At Podosky, mining commenced in May 2026 and 12 blasts have been completed to date, including four during August. Approximately 356kt of material has been moved from the pit. A further eight blasts are scheduled as pit development and mining activities continue.
The volume of scheduled blasts at both pits indicates active near-term ore supply continuity for the Blackjack processing plant.
Blake Cannavo, Managing Director & CEO
“We continue to make good progress across our mining areas, with approximately 815,000 tonnes of material now moved from Mid Pit and Podosky since April and May…”
What is gold doré and why does the refinery outturn matter?
Gold doré bars are unrefined alloys of gold and silver poured on site at the mine before being sent to an external refinery for processing. They are not pure gold — the doré bar contains a mix of metals, and the gold assay percentage tells you exactly how much of that bar is actually gold.
That assay percentage is what determines the refinery outturn: the actual refined gold recovered and credited to the producer. The 1 September 2026 smelt illustrates the point clearly. The two bars had a combined smelt weight of 403.8oz, but after assaying at a combined 47.89% gold, the refined gold outturn came to 191.99oz. The smelt weight is the gross weight of the bar; the outturn is what NMR actually gets paid for.
Understanding this distinction helps you read NMR’s production updates accurately. A large smelt weight with a low gold assay can produce a smaller outturn than a lighter smelt with a higher grade — which is why both figures matter when tracking production performance.

North Pit drilling and Stockholm JV expand NMR’s future ore pipeline
In parallel with current operations, NMR is advancing two forward-looking threads:
- Blackjack North Pit drilling is ongoing, supporting geological assessment and future mine development planning at Blackjack.
- Stockholm Tenements JV with Citigold Corporation (ASX: CTO), announced 3 September 2026: under the JV Agreement, NMR holds an exclusive licence to enter the JV Tenements and undertake exploration and proving-up drilling. The Stockholm Tenements represent an additional exploration and potential future ore source within NMR’s broader Charters Towers strategy.
NMR’s stated strategy is to maintain production from its current mining areas while progressively developing additional ore sources that could utilise the company’s existing Blackjack processing infrastructure. The Stockholm JV remains at the exploration stage and has not been confirmed as an ore source.
For readers wanting to understand the full terms and strategic rationale behind the Citigold arrangement, our detailed coverage of the Stockholm JV announcement walks through the agreement structure, the exploration commitments NMR has taken on, and how the tenements fit within the broader Charters Towers strategy.
