Diamo estimates Zlaté Hory mine value at 17.9 billion koruna

For the region, the project would be more than a mining story. Diamo says a restart could create about 120 jobs and bring annual local payments of 8.4 million koruna to Zlaté Hory and 2.9 million koruna to nearby Heřmanovice, though actual receipts would depend on output and metal prices.

The company is also pitching the project as lower impact than older mining operations. It says the ore would be extracted underground using existing shafts and blasting, processed at a former industrial site and not treated with cyanide, while no new tailings pond is planned.

That makes the economics especially sensitive to the gold price, which remains elevated by historical standards even after recent pullbacks in global bullion markets. Gold futures are trading around $4,008 an ounce, well above many miners’ all-in sustaining cost bases, while ETF tracking such as GLD has softened in recent sessions, reflecting a cooler near-term tone in the metal.

The broader investment angle is that the deposit adds to the pipeline of potential future supply in a market where investors are still weighing tight output, high metal prices and the political risks of new mine development. It also highlights the tension between centralised economic planning and local resistance: Zlaté Hory’s council rejected the idea last year, arguing it saw no clear development benefit.

Diamo says the next steps would include more drilling, a fuller economic study and environmental assessment before any permitting process. For now, the project sits at the intersection of commodity prices, regional employment and Czech industrial policy.
