Citigold Joins NMR in Charters Towers JV to Feed Existing Gold Processing Plant

Native Mineral Resources has executed a binding joint venture with Citigold Corporation over the 128-hectare Stockholm Tenements at Charters Towers — just 2km from NMR's existing Blackjack processing plant — in a staged deal that lets NMR prove up the ground before committing a single dollar to mining.

NMR expands its Charters Towers footprint with binding Citigold joint venture

Native Mineral Resources (ASX: NMR) has executed a binding joint venture agreement with Citigold Corporation (ASX: CTO), effective 3 September 2026, covering four mining leases at Charters Towers, Queensland, collectively known as the Stockholm Tenements. The JV Tenements sit approximately 2km north of NMR’s existing Blackjack Operations, creating a practical pathway to feed additional material through an already-operational plant. The structure is deliberately staged: NMR will first complete proving-up drilling before any mining decision is made.

What the Stockholm joint venture covers

Four tenements, 128 hectares, and a historic open pit

The four JV Tenements — ML1424 (Stockholm), ML1430 (Black Jack 4), ML10032 (Stockholm No. 1), and ML10042 (Stockholm No. 2) — cover a combined area of approximately 128 hectares, located roughly 7km southwest of central Charters Towers, adjacent to Diamantina Road.

Tenement Name Area (ha)
ML1424 Stockholm 8.425
ML1430 Black Jack 4 117.5
ML10032 Stockholm No. 1 1.197
ML10042 Stockholm No. 2 0.887
Total 128.009

The tenements encompass the historic Stockholm open pit, along with existing rock and topsoil stockpiles and established access roads. That physical infrastructure lowers the practical barriers to commencing a proving-up program.

Importantly, Citigold remains the registered holder of the JV Tenements and retains responsibility for the environmental authority and all relevant statutory obligations. This means NMR gains access to the ground without needing to acquire the tenements outright.

How the joint venture is structured to protect NMR

Staged pathway with NMR in the driver’s seat

The agreement operates in two distinct phases. In the first, NMR holds the exclusive right to undertake proving-up drilling and has sole operational control of that work. In the second, following receipt and assessment of final drilling and assay results, NMR may elect whether to proceed to mining operations. If NMR elects not to proceed, the agreement terminates in accordance with its terms.

NMR’s operational control is broad, covering mine planning, contractors, processing, blending, transport, refining, and sale.

The commercial terms are structured as follows:

  • Cost recovery: NMR may recover costs actually and reasonably incurred in connection with proving-up drilling, development, and mining operations. Eligible NMR costs include an 8% margin on specified cost categories, subject to the terms of the agreement. Citigold may recover specified statutory and environmental authority costs attributable to the JV Tenements.
  • Surplus sharing: For each smelt event, the Queensland mineral royalty, unrecovered NMR costs, and unrecovered Citigold costs are deducted from gross smelt proceeds. Any remaining surplus is shared equally (50:50) between NMR and Citigold.
  • Carry forward: Unrecovered costs carry forward to later smelt events.

Stockholm Joint Venture Commercial Structure

No drilling timeline, budget, or resource estimate has been disclosed in the announcement.

Why proximity to Blackjack makes this deal strategically logical

For investors unfamiliar with the term, a proving-up drilling program is a targeted campaign to determine whether mineralisation within a tenement is sufficiently consistent and of sufficient grade to support an economically viable mining decision. The purpose is to gather enough geological evidence before committing capital to full-scale mining infrastructure.

This is where the Stockholm deal becomes particularly interesting. Because the JV Tenements sit approximately 2km from NMR’s Blackjack processing plant, any material that proves up could be hauled and processed through existing infrastructure. NMR would not need to build new processing capacity to bring that material into production.

That matters because processing infrastructure is typically one of the most capital-intensive components of a mining operation. If the drilling results support development, the Stockholm Tenements could represent an additional source of feed for Blackjack at marginal incremental cost rather than requiring a ground-up build.

What both companies are saying

Blake Cannavo, Managing Director & CEO, NMR

“The Stockholm joint venture provides NMR with a staged opportunity to assess additional mineralised material close to our Charters Towers operations without acquiring the tenements. We will first complete proving-up drilling before deciding if mining should proceed. If successful, the joint venture could provide an additional source of feed for our Blackjack operations.”

Mark Lynch, Executive Chairman, Citigold

“The Stockholm joint venture brings together Citigold’s Charters Towers tenements and NMR’s established operational and processing capabilities. The staged approach allows the parties to first establish the potential of the Stockholm tenement mineralisation through proving-up drilling before committing to mining operations. If the results support development, the joint venture provides a practical pathway to bring additional mineralised material into production for the benefit of both companies.”

Next steps for NMR investors to watch

NMR will now progress through the following sequence:

  1. Detailed planning for the proving-up drilling program, including the proposed drilling sequence, contractor requirements, and applicable operational and regulatory arrangements
  2. Completion of drilling and receipt of assay results
  3. NMR’s election whether to proceed to mining operations
  4. Further ASX updates as material information becomes available

Investors should note the agreement is conditional on drilling outcomes. There is no certainty that the proving-up drilling will support a decision to proceed, or that mining operations will ultimately commence.

Frequently Asked Questions

What is the Citigold Stockholm joint venture agreement with NMR?

The Citigold Stockholm joint venture is a binding agreement between Native Mineral Resources (ASX: NMR) and Citigold Corporation (ASX: CTO), effective 3 September 2026, giving NMR the exclusive right to conduct proving-up drilling across four mining leases totalling 128 hectares at Charters Towers, Queensland, with the option to proceed to mining if results support it.

What does proving-up drilling mean in the context of the Stockholm tenements?

Proving-up drilling is a targeted campaign to determine whether mineralisation within a tenement is consistent enough and of sufficient grade to support an economically viable mining decision — it's the geological evidence-gathering phase that comes before committing capital to full-scale mining infrastructure.

How are profits split between NMR and Citigold under the Stockholm JV?

After deducting Queensland mineral royalty and unrecovered costs for both parties — with NMR entitled to an 8% margin on specified cost categories — any remaining surplus from each smelt event is shared equally 50:50 between NMR and Citigold, with unrecovered costs carrying forward to later events.

Why does the Stockholm tenement location matter for NMR's Blackjack operations?

The Stockholm Tenements sit approximately 2km from NMR's existing Blackjack processing plant, meaning any material that proves up could be processed through already-operational infrastructure rather than requiring a new capital build — significantly reducing the cost of bringing Stockholm material into production.

What are the next steps for NMR following the Stockholm JV announcement?

NMR will first complete detailed planning for the proving-up drilling program, then conduct drilling and receive assay results, before making an election on whether to proceed to mining operations — with further ASX updates promised as material information becomes available.
