JUBILEE METALS GROUP PLC - FY2026 Production and Operational Update
What this filing means
A two-tier operational print: production scaled fast while the refining part of the business faced a material cost squeeze. Combined copper output from Roan and Molefe surged 225% to 3,739t, but final products for sale grew only 1.3% to 2,120t — most of the production gain is stockpiled oxide fines awaiting the dewatering circuit. Separately, domestic acid costs in Zambia rose over 200% and diesel 90% in Q4, squeezing Sable with no offsetting pass-through or margin impact quantified.
Jubilee mined and processed far more copper than last year, but most of it is sitting in a stockpile rather than being sold. The refinery that turns it into cash is being squeezed by much higher acid and diesel costs in Zambia. So the headline growth number looks impressive, but the money-making part of the business barely moved — and the company has not said how it plans to absorb the higher costs or pass them on.
Bull case
- Combined copper production from Roan and Molefe rose 225% YoY to 3,739t Cu in FY2026, evidencing rapid vertical integration of Jubilee-controlled feed sources.
- Roan graduated to stable-state operating status with the first formal FY2027 production guidance of 2,850-3,150t Cu, anchoring forward visibility for Jubilee's largest feed source.
- The US$35m LWP binding Heads of Terms remain on track with due diligence concluding imminently, monetising a non-core asset as Jubilee pivots to integrated mining.
- Phase-2 drilling at Molefe indicates potential of approximately 1,740tpa of contained Cu in HG ROM to Sable, with formal guidance on the 10,000tpm target still pending sustained stable-state demonstration.
Bear case
- Final saleable copper output (cathode plus sulphide concentrate) grew only 1.3% YoY to 2,120t, while gross production surged 225% to 3,739t — most of the headline gain sits as unsold oxide fines stockpile rather than cash-generating product.
- Sulphide concentrate — the stream sold directly into the market — fell 14.4% YoY to 913t, making it the only directly cash-generating copper stream to contract.
- Zambian acid costs rose over 200% and diesel 90% in Q4 FY2026, forcing area processor closures and marked impact at Sable, yet the filing gives no offsetting cost pass-through, hedge or margin quantification.
- Roan's FY2027 guidance of 2,850-3,150t covers a full year of stable-state operations but excludes any contribution from oxide fines that remain stockpiled pending full dewatering circuit ramp-up, meaning near-term growth from Roan depends on the fines circuit achieving throughput at design capacity.
- Molefe's 10,000tpm target is explicitly 'project target rather than production guidance', with formal guidance still pending sustained stable-state demonstration — a downgrade of growth visibility.

SENS-AI conclusion
A two-tier operational print: the production engine is scaling fast while the refining economics face a material cost headwind the filing does not quantify. The 225% production surge is real, yet the 1.3% growth in saleable product and the 14.4% fall in directly-sold sulphide concentrate show the economics have not yet caught up. The Q4 acid and diesel cost spike — acid up over 200%, diesel up 90% — is disclosed as a fact with no margin, cost-pass-through or hedge detail. So what: the strategy is progressing on the production side, but the market still needs the audited accounts to show whether the cost squeeze at Sable is being absorbed or is materially eroding margins.
The audited FY2026 results are where the market will test whether the acid and diesel cost spike at Sable is being absorbed or is eroding margins.
Evidence from the filing
Combined copper production from Roan and Molefe rose 225% YoY to 3,739t Cu in FY2026, evidencing rapid vertical integration of Jubilee-controlled feed sources.
“Combined copper production prior to refining from the Roan operations and Molefe Mine totalled 3 739t of copper (Cu) for FY2026, an increase of 225.0% from 1 149t in FY2025”
Roan graduated to stable-state operating status with the first formal FY2027 production guidance of 2,850-3,150t Cu, anchoring forward visibility for Jubilee's largest feed source.
“Roan has now reached stable operational output (stable state) with a forecasted operational output for FY2027 of between 2 850t and 3 150t of Cu”
The US$35m LWP binding Heads of Terms remain on track with due diligence concluding imminently, monetising a non-core asset as Jubilee pivots to integrated mining.
“Binding Heads of Terms for the sale of the Large Waste Project (LWP) for a consideration of US$35 million with an option for accelerated settlement for a reduced consideration of US$30 million”
Phase-2 drilling at Molefe indicates potential of approximately 1,740tpa of contained Cu in HG ROM to Sable, with formal guidance on the 10,000tpm target still pending sustained stable-state demonstration.
“Current indications from the drilling results suggest Molefe holds the potential to deliver approximately 1 740tpa of contained Cu in HG ROM to Sable which excludes the LG ROM being stockpiled for future processing at site”
Final saleable copper output (cathode plus sulphide concentrate) grew only 1.3% YoY to 2,120t, while gross production surged 225% to 3,739t — most of the headline gain sits as unsold oxide fines stockpile rather than cash-generating product.
“Combined cathode and copper sulphide concentrate produced for sale reached 2 120t of Cu in FY2026, a year-on-year increase of 1.3%”
Sulphide concentrate — the stream sold directly into the market — fell 14.4% YoY to 913t, making it the only directly cash-generating copper stream to contract.
“Cu in sulphide concentrates decreased by 14.4% to 913t reflecting the increased treatment of oxide ores during the period and demonstrating Roan's flexibility to process varying ore types”
Zambian acid costs rose over 200% and diesel 90% in Q4 FY2026, forcing area processor closures and marked impact at Sable, yet the filing gives no offsetting cost pass-through, hedge or margin quantification.
“During Q4 FY2026, domestic acid availability reduced significantly resulting in tighter supply conditions as well as the cost increasing by in excess of 200%, whilst diesel costs increased by 90%”
Molefe's 10,000tpm target is explicitly 'project target rather than production guidance', with formal guidance still pending sustained stable-state demonstration — a downgrade of growth visibility.
“The 10 000tpm level therefore remains a project target rather than production guidance”
