Blanket Mine Q3 Production and Revised guidance

Production and cost guidance cut as operational setbacks hit Caledonia’s Blanket Mine.

What the company is saying

Caledonia Mining Corporation Plc reports a significant shortfall in Q3 2026 gold production at the Blanket Mine in Zimbabwe, producing 17,030 ounces versus 19,106 ounces in Q3 2025. The company attributes the decline to a shortage of compressed air in high-grade mining areas and a temporary increase in gold inventory within the metallurgical plant. Management details remedial actions, including the procurement and partial deployment of four new compressors and the commissioning of new gravity circuit equipment, with the expectation that normalised production will resume in Q4. Revised full-year 2026 guidance lowers expected gold output to 69,000–72,500 ounces (from 72,000–76,500 ounces) and increases on-mine cost guidance to US$1,700–US$1,900 per ounce sold (from US$1,600–US$1,800), with AISC now at US$2,650–US$2,850 per ounce (from US$2,500–US$2,700). Capital expenditure guidance is reduced to US$94.3 million (from US$103.3 million), mainly due to timing changes for the 132kV power line project, not scope reductions. CEO Mark Learmonth acknowledges the operational setbacks and outlines steps to recover lost production and improve consistency in 2027. Technical disclosures are reviewed and approved by Craig James Harvey, Vice President, Technical Services.

What the data suggests

Q3 2026 gold production at Blanket Mine fell to 17,030 ounces, down 11% from 19,106 ounces in Q3 2025, with nine-month output dropping to 49,158 ounces from 58,846 ounces year-over-year. Tonnes milled increased slightly to 215,539 in Q3 2026, but grade declined to 2.67 g/t (from 3.00 g/t) and recovery slipped to 92.2% (from 93.3%). Operational disruptions included compressed air shortages and commissioning issues with new gravity circuit equipment, resulting in 1,100 ounces of gold temporarily retained in the plant. Revised FY 2026 production guidance is now 69,000–72,500 ounces, implying a lower Q4 target of 19,800–23,300 ounces. Cost pressures are evident, with on-mine cost guidance raised to US$1,700–US$1,900 per ounce and AISC to US$2,650–US$2,850 per ounce. Capex for FY 2026 is cut to US$94.3 million, with key allocations of US$44.0 million sustaining capital at Blanket, US$3.5 million growth capital at Blanket, US$43.0 million at Bilboes, and US$3.8 million at Motapa. The company asserts that internal cash flows remain sufficient to support Bilboes development, but provides no detailed cash flow evidence. The data shows a clear operational and financial deterioration, with management’s recovery plan hinging on near-term equipment fixes and process improvements.

Analysis

The announcement is measured in tone and does not exaggerate progress; it openly reports a year-over-year decline in gold production, lower grades, and higher costs, with revised (lowered) guidance for both production and cost metrics. While management expresses confidence that operational improvements and equipment upgrades will benefit Q4 and 2027, these are presented as expectations rather than certainties, and are supported by specific remedial actions (e.g., compressor procurement, elution vessel commissioning). The majority of forward-looking statements relate to near-term operational recovery (mid-October and Q4 2026), not distant or aspirational targets. Capital intensity is high, with $94.3 million in FY 2026 capex, but this is disclosed transparently and paired with reduced guidance, not promotional claims. There is no evidence of narrative inflation or overstatement; if anything, the tone is cautious and factual, with no attempt to obscure operational setbacks.

Risk flags

• ●Operational risk is elevated due to recent failures in compressed air supply and delays in deploying new compressors, which directly impacted production in high-grade zones. If equipment commissioning or logistics face further setbacks, Q4 recovery targets may be missed.
• ●Cost risk is rising, as both on-mine and all-in sustaining cost guidance have been revised upward. Lower production volumes and persistent operational inefficiencies could further pressure margins if not resolved quickly.
• ●Execution risk remains around the recovery of 1,100 ounces of retained gold and the processing of 58.04 tonnes of activated carbon containing 1,166 ounces. Any further technical or commissioning issues could delay or reduce the expected production uplift.
• ●Financial risk is present in the company’s assertion that internal cash flows will fund the Bilboes development project, as no supporting cash flow or balance sheet data is disclosed. If operational recovery stalls, funding for growth projects could be jeopardised.
• ●Grade and recovery risk is evident, with both metrics declining year-over-year. Sustained lower grades or recoveries would undermine future production and cost targets.

Bottom line

Caledonia Mining’s Q3 2026 update signals a material operational and financial setback at the Blanket Mine, with gold output, grade, and recovery all declining and cost guidance moving higher. Management’s plan to restore production hinges on resolving compressed air and processing bottlenecks, with most corrective actions due to take effect within weeks. While the company reduces capex to match cash flow expectations, this is driven by timing deferrals rather than efficiency gains. The credibility of the recovery narrative will depend on Q4 execution, particularly the timely recovery of retained gold and successful deployment of new equipment. Investors should focus on realised Q4 production, cost performance, and evidence of cash flow sufficiency to support ongoing development at Bilboes. The key takeaway is that operational risks remain high, and near-term delivery is critical for restoring confidence.

Announcement summary

(LSE:DI) Caledonia Mining Corporation Plc announced gold production results for the Blanket Mine in Zimbabwe for Q3 2026 and issued revised guidance for the full year 2026. Gold produced in Q3 2026 was 17,030 ounces, compared to 19,106 ounces in Q3 2025. Gold produced in the nine months ended September 30, 2026 was 49,158 ounces, down from 58,846 ounces in the same period of 2025. Tonnes milled in Q3 2026 were 215,539, with a grade (BUH) of 2.67 and recovery of 92.2%. For the nine months, tonnes milled were 625,904, grade was 2.65, and recovery was 92.3%. Production was negatively impacted by a shortage of compressed air at high-grade mining areas and a temporary increase in gold inventory in the metallurgical plant. Four new compressors were procured, with two now deployed and two in transit to the mine. Approximately 1,100 ounces of free-gold were retained in the metallurgical plant due to commissioning difficulties with new gravity circuit equipment; this gold is expected to be recovered starting mid-October after increased elution capacity is commissioned. Revised FY 2026 production guidance for Blanket is now 69,000 to 72,500 ounces, down from 72,000 to 76,500 ounces. Q4 2026 production is expected to be 19,800 to 23,300 ounces. Q4 production is anticipated to benefit from increased compressed air capacity, recovery of the 1,100 ounces of retained gold, processing of additional ore at the Lima satellite plant, improved mining flexibility, and increased elution capacity, including processing 58.04 tonnes of activated carbon containing approximately 1,166 ounces of gold at an average grade of 625.0 grammes per tonne. On-mine cost per ounce sold guidance is revised to US$1,700–US$1,900 (previously US$1,600–US$1,800). All-in sustaining cost (AISC) guidance is revised to US$2,650–US$2,850 per ounce sold (previously US$2,500–US$2,700). Group capex guidance for FY 2026 is reduced to US$94.3 million (previously US$103.3 million), reflecting timing changes, mainly for the 132kV power line project. Capex guidance includes US$44.0 million sustaining capital at Blanket (reduced from $48.0m), US$3.5 million growth capital at Blanket (unchanged), US$43.0 million growth capital at Bilboes (previously $48.0m), and US$3.8 million exploration at Motapa (unchanged). Management states the revised guidance will not adversely affect the Group's ability to use internal cash flows for the Bilboes development project. Mark Learmonth, Chief Executive Officer, commented on the operational challenges and outlined steps being taken to address them. Craig James Harvey, Vice President, Technical Services, is the Qualified Person who reviewed and approved the technical information.
