I think its more hype and pipe dream.
The cost of extraction and processing per ton has to be less than what is recovered per tone of ore. The profit margin has to have a enough margin to handle gold price fluctuations. Sulfide and oxide gold deposits are not inherently easy, but their difficulty varies: oxides are often simpler (leachable), while sulfides present complex challenges like "locked gold," consuming cyanide and requiring complex flotation/smelting, making them harder but potentially richer. Oxide deposits are generally more straightforward to process, often through cyanide leaching if free gold is present, but sulfides need intensive pre-treatment like flotation to separate minerals before smelting, adding significant cost and complexity.
Also I do not think much Western foreign hedge fund capital will be flowing into Iran to develop the mine. Sanctions on Iran are comprehensive, multi-layered restrictions imposed by the UN, US, EU, and other nations, targeting its nuclear & missile programs, energy sector, financial system, and entities like the IRGC, prohibiting arms/tech transfers, freezing assets, and imposing travel bans to pressure Iran on nuclear compliance and regional activities, impacting its oil, trade, and currency.
At present I can not see a viable preposition in the making. Russia and China through Iran under the bus. Russian and china has their own gold reserves to invest in. Half of Arab word is at odds with Iran. So a notable ore deposit discovery but ground not breaking.
