Ivanhoe stuns market with deep DRC copper output cut

Ivanhoe Mines (TSX: IVN) has slashed near-term production guidance for its flagship Kamoa-Kakula copper complex in the Democratic Republic of Congo, surprising analysts and resetting investor expectations.

The company now expects 2026 copper anode output of 290,000 to 330,000 tonnes, down from 380,000 to 420,000 tonnes, while 2027 production will reach 380,000 to 420,000 tonnes versus a prior 500,000 to 540,000 tonnes.

Ivanhoe released the update after markets closed Tuesday, citing a shift toward underground development, rehabilitation and access work that will constrain ore delivery over the next 18 to 24 months. The company also raised expected cash costs, compounding the weaker outlook.

“The headline takeaway was a material reset to near-term expectations,” Jefferies analyst Fahad Tariq said in a note, adding that investors were not anticipating the downgrade. “We view the update as a clear acknowledgment that operational challenges at Kakula are taking longer to resolve than initially envisaged, pushing volume recovery further out.”

New model

At the core of the revision is a new reserve model that cut contained copper by 25% and reduced reserve grade by 28%, reflecting more conservative assumptions, lower cutoff grades and revised mine sequencing. Ivanhoe now caps underground extraction rates at about 60%, down from 70% to 80% or higher, as it widens pillars and excludes inaccessible areas to improve long-term stability.

The reset underscores a broader trade-off facing large mining projects: sacrificing short-term output to secure more reliable, efficient production over time, forcing investors to recalibrate expectations.

BMO analysts said the reserve update appears conservative but carries more significant implications for near-term production and valuation, largely due to the lower grade profile.

“The reserve update for Kakula/Kamoa came in below both the market’s and our expectations,” analyst Andrew Mikitchook wrote. “The largest impact on valuations comes from a 28% decrease in reserve grade.”

Revised outlook

BMO cut its price target on Ivanhoe shares to $16 from $23, citing weaker near-term output and revised long-term assumptions. Year-to-date, the stock is down almost 24%, trading at $11.89 on Wednesday morning in Toronto, and has fluctuated within a range of $8.76 to $20.34 in the first three months of 2026.

The bank also highlighted a planned redevelopment of the complex in 2026 and 2027, aimed at enabling broader and more efficient mining with faster backfill sequencing, though at the cost of reduced extraction rates in the interim.

Despite the downgrade, BMO said there is potential upside as Ivanhoe continues to refine its mine plan. Ongoing optimization work, including geotechnical drilling and further analysis of Kakula East, could lead to improved efficiency, with an updated prefeasibility and feasibility plan expected in the first quarter of 2027.

Jefferies similarly noted that mine plans for 2026 and 2027 now focus explicitly on development and rehabilitation rather than production, with slower advance rates and more conservative sequencing reducing ore delivery and raising costs in the near term.

Long-term safe

Ivanhoe continues to target annual copper production exceeding 500,000 tonnes from 2028, positioning Kamoa-Kakula among the world’s largest copper operations.

The current redevelopment stage aims to unlock that scale by improving underground access, expanding mining areas and enabling more consistent extraction, even as it delays the ramp-up profile that had supported prior market expectations.

Analysts said the company’s more cautious approach reflects a focus on long-term performance and stability after persistent operational challenges at Kakula.

Near-term sentiment will hinge on execution, including improved operating performance, timely redevelopment progress and clearer visibility on the next iteration of the mine plan, with signs of progress later this year likely key to rebuilding investor confidence.
