Highlights

  • Resolute Mining (ASX:RSG) reported a substantial first-half Earnings improvement despite operational pressures at Syama.
  • St Barbara (ASX:SBM) continues to rebuild around Simberi and its Atlantic Gold portfolio, with funding, permitting and development execution central to the outlook.
  • PLS Group (ASX:PLS) returned to profitability in FY2026 as lithium-market conditions improved and Pilgangoora delivered record production.
  • Commodity volatility, operational execution and growth discipline remain important across the three companies.

Two very different Commodity cycles are shaping these three ASX-listed miners. Gold-market conditions remain highly supportive for producers, while lithium is recovering from a prolonged downturn but continues to experience significant volatility.

August reporting season sharpened the contrast. Resolute Mining (ASX:RSG) posted a substantial first-half profit improvement on 20 August 2026 despite operational strain in Mali. PLS Group (ASX:PLS) returned to a A$526 million full-year profit as lithium-market conditions improved, while St Barbara (ASX:SBM) continued rebuilding its operating and development portfolio around Simberi and Atlantic Gold.

Together, the three companies show how the same resources market can reward established precious-metals production while cautiously reassessing battery-metals recovery.

Why the Gold and Lithium Sector Is in Focus in September 2026

Gold and lithium are moving through very different parts of their respective cycles.

For gold producers, supportive pricing conditions are expanding cash margins and strengthening balance sheets, giving companies greater flexibility to fund exploration, development and acquisitions.

The lithium story is about recovery from oversupply. Market conditions have improved materially from earlier lows, but prices remain volatile as Supply restarts, Chinese Demand and operating disruptions continue to influence the balance between production and consumption.

Key drivers investors are monitoring:

  • Gold-market conditions and their effect on producer Cash Flow and project economics
  • The durability of the lithium recovery and the pace of new supply
  • Jurisdictional and operational risk, particularly for offshore and concentrated producers
  • Project execution, production guidance and cost control
  • The 29 September RBA decision as a broader sentiment and currency variable

Why Resolute Mining Limited (ASX:RSG) Is in Focus

Resolute Mining Limited (ASX:RSG) is an African-focused gold producer operating the Syama mine in Mali and the Mako mine in Senegal.

Its half-year results to 30 June 2026, reported on 20 August, showed how favourable gold-market conditions can offset operational headwinds. Revenue rose about 31% to roughly US$584.7 million, while net profit after tax increased to about US$162.6 million from US$71.0 million a year earlier. EBITDA rose around 42% to US$323.9 million.

Gold sales totalled 123,951 ounces at an average realised price of about US$4,712 an ounce.

Production, however, declined to 104,795 ounces from 151,460 ounces a year earlier. Syama contributed 73,683 ounces at an All-In Sustaining Cost of about US$2,399 an ounce, affected by explosive-supply constraints and a planned roaster shutdown. Mako contributed 31,112 ounces at an AISC of about US$1,605 an ounce.

Resolute Mining (ASX:RSG) finished the period with net cash of around US$317.4 million.

Management maintained full-year guidance of 250,000–275,000 ounces, targeting the lower end, at an AISC of US$2,000–2,200 an ounce. The company also continues to advance the Doropo project in Côte d'Ivoire, where first gold is targeted for the second half of 2028.

Operational stability at Syama, cost control and progress at Doropo remain the main issues to monitor.

Why St Barbara Ltd. (ASX:SBM) Is in Focus

St Barbara Ltd. (ASX:SBM) is rebuilding around two core areas: the Simberi gold operation in Papua New Guinea's New Ireland Province and the Atlantic Gold portfolio in Nova Scotia, Canada.

The company reported its June-quarter FY2026 results on 20 July 2026 and continues to work through a transition phase as it develops a clearer path toward sustainable production and growth.

At Simberi, management is working to extend mine life and transition toward processing sulphide ores. The development pathway includes funding, technical and Partnership considerations that remain important to future production.

In Nova Scotia, St Barbara (ASX:SBM) holds the mothballed Touquoy operation alongside a broader pipeline of deposits. On 5 August 2026, it announced accelerated exploration activity and has also reported progress on permitting across its Atlantic portfolio.

For St Barbara (ASX:SBM), the operating environment is supportive, but the Investment case depends primarily on execution — progressing funding, permitting and development milestones across both Simberi and Nova Scotia.

Why PLS Group Limited (ASX:PLS) Is in Focus

PLS Group Limited (ASX:PLS), formerly Pilbara Minerals, operates the Pilgangoora hard-rock lithium project in Western Australia.

Its FY2026 results, reported on 24 August 2026, marked a return to profitability as lithium-market conditions improved. Net profit after tax reached about A$526 million, reversing a A$196 million loss in FY2025, while revenue was roughly A$1.93 billion.

Operationally, FY2026 was a record year. Spodumene concentrate production of 879,500 tonnes exceeded prior guidance of 820,000–870,000 tonnes, while sales reached 891,600 tonnes. Fourth-quarter production totalled 214,300 tonnes and sales reached 249,900 tonnes.

Realised pricing improved materially through the year as lithium conditions recovered. The Ngungaju plant restart commenced in July 2026, adding capacity as operating conditions improved.

Beyond mining, PLS Group (ASX:PLS) continues to pursue a broader strategy spanning operations, growth, chemicals and diversification. The P2000 brownfield expansion at Pilgangoora remains under evaluation and subject to approvals, while the company is also progressing a South Korean Downstream joint-venture demonstration Facility and the Colina lithium project in Brazil.

Lithium pricing, cost discipline and decisions around future expansion remain central to the outlook.

What Connects These Three Stocks?

At first glance, these are two gold stories and one lithium story. The connection is that all three are commodity price-takers whose operating and financial outcomes are being reshaped by cycles moving in different directions.

Resolute Mining (ASX:RSG) and St Barbara (ASX:SBM) are exposed to supportive gold-sector conditions, but they sit at different points in the producer spectrum. Resolute is an established multi-mine operator generating meaningful cash flow, while St Barbara remains a smaller rebuilding story focused on converting existing Assets into more consistent production.

PLS Group (ASX:PLS) is operating within a different cycle entirely. Lithium is recovering from a deep downturn, and the company has returned to profitability rather than benefiting from historically elevated pricing conditions.

Geography also separates the three. Resolute operates in Mali and Senegal, St Barbara in Papua New Guinea and Canada, and PLS primarily in Western Australia while pursuing international growth options.

The comparison shows how commodity cycle, operating maturity, Jurisdiction and balance-sheet position can produce very different outcomes across the resources sector.

What Could Move These Stocks Next?

  • Resolute Mining: Second-half production against guidance, cost performance and operating stability at Syama, progress at Doropo, and gold-market conditions.
  • St Barbara: Simberi development and funding milestones, Nova Scotia permitting and exploration progress, and future production guidance.
  • PLS Group: Lithium and spodumene pricing, any P2000 investment decision, the Ngungaju ramp-up, and downstream and Brazilian growth milestones.
  • Sector-wide: Chinese demand, currency movements and the 29 September RBA decision.

What Are the Risks?

Commodity conditions remain central.

A weaker gold environment would pressure margins and project Economics for Resolute Mining (ASX:RSG) and St Barbara (ASX:SBM), while lithium Volatility remains PLS Group (ASX:PLS)'s principal external risk. Further supply restarts or softer Chinese demand could slow the recovery.

Resolute carries elevated jurisdictional and operating risk in Mali, including regulatory, security and supply-chain considerations, alongside operational challenges such as explosive availability and roaster reliability.

St Barbara (ASX:SBM) faces execution, funding and permitting risks across two different jurisdictions while rebuilding its production base.

PLS Group (ASX:PLS) must balance large potential expansion spending against an uncertain lithium-market outlook and the possibility of renewed oversupply.

Currency movements, cost Inflation and project execution remain relevant across all three.

What ASX Investors Should Watch Next

For Resolute Mining (ASX:RSG), the main test is operational reliability at Syama and delivery against full-year production and cost guidance while Doropo advances.

For St Barbara (ASX:SBM), attention centres on execution — securing funding, progressing permits and establishing a clearer path to sustainable production across Simberi and Nova Scotia.

For PLS Group (ASX:PLS), investors will be watching operating costs, Ngungaju's ramp-up and how aggressively the company chooses to pursue expansion while lithium conditions remain volatile.

Across all three, production updates, guidance, project milestones and commodity-market developments should provide the clearest indicators of progress through the remainder of 2026.
