Caledonia Cuts Blanket Gold Guidance as Compressor Delays Raise Costs

Caledonia Mining has cut 2026 production guidance for its Blanket mine after a weak third quarter exposed the operating cost of delayed compressed-air capacity and reduced access to deeper, higher-grade mining areas.

Blanket produced 17,030 ounces of gold in the third quarter, down from 19,106 ounces in the prior-year period. Nine-month production fell to 49,158 ounces from 58,846 ounces a year earlier. Although milled tonnes increased, lower grade and recovery outweighed that volume gain, leaving the operation with a materially lower production base entering the final quarter. 1

The company now expects Blanket to produce 69,000 to 72,500 ounces in 2026, compared with prior guidance of 72,000 to 76,500 ounces. The reduction is not simply an adjustment to a long-range plan: it makes the final quarter central to whether Caledonia can limit the full-year shortfall. The revised range implies fourth-quarter output of roughly 19,800 to 23,300 ounces, above the 17,030 ounces delivered in the third quarter. 12

That recovery is contingent on operational improvements rather than an already completed result. Delays installing four compressors created compressed-air shortages that restricted mining in deeper areas, where higher grades were expected. Two compressors had been deployed by the time of the update, while the other two had cleared port, according to Caledonia. Additional air capacity should improve access to the affected stopes, but the production guidance now embeds the risk that installation, mine access and mining performance must all improve promptly enough to lift output during the remaining quarter. 1

A separate processing issue also affected reported production. New gravity-circuit equipment temporarily retained approximately 1,100 ounces of gold. Caledonia expects that inventory to be recovered from mid-October after increasing elution capacity. The retained ounces offer a defined source of potential fourth-quarter output, but they do not by themselves close the gap to the revised annual target. Higher mine production and better recovery will still be required for Blanket to reach the upper end of guidance. 12

Costs are moving in the opposite direction. Caledonia raised on-mine cost guidance to US$1,700–US$1,900 per ounce sold, from US$1,600–US$1,800 previously. All-in sustaining cost guidance increased to US$2,650–US$2,850 per ounce, from US$2,500–US$2,700. Lower output generally spreads fixed operating costs over fewer sold ounces, and the revised ranges mean the expected fourth-quarter rebound has a direct bearing on the mine’s cost performance as well as its production total. 2

The company also reduced group capital-expenditure guidance to US$94.3 million from US$103.3 million, principally because components of its 132kV power-line project have been moved into 2027. Caledonia said there was no material reduction in the project’s scope. The revised spending plan includes US$44.0 million of sustaining capital at Blanket, US$3.5 million of Blanket growth expenditure, US$43.0 million for Bilboes growth and US$3.8 million for Motapa exploration. 2

For Caledonia, the immediate issue is execution at Blanket rather than an expansion of its asset base. The company has identified the equipment and processing constraints behind the setback, and some corrective steps are already under way. But the lower guidance and higher cost ranges establish a demanding fourth-quarter benchmark. Delivery of the compressors, restored access to deeper ore and release of retained gold inventory must translate into sustained operational performance before the expected recovery can be counted as achieved.
