Kamoa-Kakula Q1 Copper Concentrate Output Falls 54% Year on Year, Ivanhoe Weighs Third-Party Purchases

Why It Matters

The shortfall in concentrate feed and sulfuric acid scarcity threaten Ivanhoe’s margin outlook and could tighten global copper markets, especially for SX‑EW‑derived copper, driving price volatility.

Key Takeaways

• Kamoa‑Kakula smelter produced 1,350 t/d sulfuric acid, 480k t annualized
• Copper concentrate output fell 54% YoY to 61,906 t in Q1
• Production guidance cut to 290‑330k t copper anode for 2026
• Sulfuric acid shortages threaten SX‑EW copper, affecting 20% of global supply
• Ivanhoe evaluating third‑party concentrate purchases to boost smelter ramp‑up

Pulse Analysis

The Kamoa‑Kakula complex’s newly commissioned smelter is now delivering sulfuric acid at 1,350 tonnes per day, roughly 480,000 tonnes on an annualized basis. While this by‑product creates a valuable margin stream, it remains short of the plant’s 700,000‑tonne design capacity, underscoring the early‑stage nature of the operation. The acid is being sold to six local offtakers in the DRC Copperbelt, and spot prices have risen amid broader market tightness caused by disruptions to seaborne sulfur shipments from the Middle East.

Global supply constraints on sulfuric acid are reverberating through the solvent‑extraction‑electrowinning (SX‑EW) sector, which relies on the chemical to leach copper from oxide ores. Approximately 20% of worldwide copper output depends on SX‑EW, and with about half of the seaborne sulfur supply cut off, traders anticipate upward pressure on copper prices. China’s export volumes of sulfuric acid have slumped nearly 47% year‑over‑year, and domestic price spikes are feeding into higher treatment and refining charges for copper concentrates, further compressing margins for miners.

Facing a 54% decline in concentrate feed, Ivanhoe has trimmed its 2026 copper production target to 290‑330 kt, a significant downgrade from earlier guidance. Management is actively assessing the purchase and toll‑treatment of third‑party concentrates to accelerate smelter ramp‑up and protect profitability. This strategic shift reflects a broader industry trend of diversifying feed sources amid geopolitical supply shocks, positioning Ivanhoe to mitigate risks while capitalising on the premium that sulfuric‑acid‑rich by‑products can command in a constrained market.
