Recovers copper from exhaustible Soviet waste dumps in Kazakhstan via acid leaching and extracts zinc-lead sulfide ore from a continuously dewatered underground mine in North Macedonia.
At Kounrad, sulfuric acid percolates through Soviet-era waste rock over months, and because that chemistry cannot be paused without destroying the acid gradient and biological equilibrium already embedded in the dump, the facility must run continuously or lose the processing conditions it depends on — conditions that also cannot be shortened by capital, only replicated across additional heap pads within a fixed tailings boundary that Soviet operations deposited and that no current activity can extend. That same finite, irreplaceable feedstock means each tonne of cathode produced permanently reduces the remaining resource, so the throughput ceiling and the depletion clock are the same constraint. At Sasa, continuous underground dewatering and ventilation are equally non-negotiable, because any interruption collapses the structural conditions that make the workings safe, binding zinc and lead concentrate output to the same continuous-or-zero logic. The requalification friction that copper cathode buyers face on the London Metal Exchange, and that zinc and lead concentrate purchasers face when validating alternative ore chemistry, creates switching costs that stabilize offtake relationships — but those relationships rest on an asset base that is consumed by the very process that makes it operable.
How does this company make money?
Copper cathode is sold at London Metal Exchange spot prices minus treatment charges to Chinese and regional fabricators. Zinc and lead concentrates are sold through annual off-take agreements with European smelters at benchmark treatment charges plus quality adjustments.
What makes this company hard to replace?
Copper cathode buyers face London Metal Exchange specification requalification when switching suppliers. Zinc and lead concentrate purchasers must revalidate smelter feed specifications to account for different ore chemistry from alternative mines.
What limits this company?
Copper cathode output at Kounrad is bounded by the multi-month acid percolation timeline through waste rock: no capital investment can shorten the chemistry, so throughput cannot be accelerated, only replicated across additional heap pads within the fixed Soviet-era tailings footprint, which itself cannot be extended beyond the historically deposited waste boundary.
What does this company depend on?
Kounrad depends on a continuous sulfuric acid supply for heap leaching, Kazakhstani mining licenses and environmental permits to operate the facility, and an electrical grid connection to power the electrowinning process. Sasa depends on North Macedonian underground mining permits to maintain the workings. Both operations depend on rail freight access to export terminals.
Who depends on this company?
European zinc smelters purchasing Sasa concentrates would face supply shortfalls and would need to source substitute concentrates from Turkey or Bulgaria. Chinese copper fabricators buying Kounrad cathode would need replacement material from Chilean or Peruvian producers, at higher transport costs.
How does this company scale?
Additional heap leach pads at Kounrad can replicate the solvent extraction process across more areas of the waste dump. However, scaling is constrained by the fixed geographic boundary of the Soviet-era mining waste at the Kounrad site, which cannot be expanded beyond the existing tailings footprint.
What external forces can significantly affect this company?
Kazakhstani government resource nationalism affects mining taxation and export licensing for the Kounrad facility. European Union environmental regulations on mining waste management bear on Sasa's operations in North Macedonia. Chinese economic growth cycles drive demand volatility for Kounrad cathode.
Where is this company structurally vulnerable?
Because the waste dump is finite and was generated by operations that cannot be restarted, each tonne of cathode produced permanently reduces the remaining resource. Once the Soviet-era tailings footprint is exhausted, the same property that made the feedstock inaccessible to competitors makes replenishment impossible for the operator.
