Rio Tinto declined to comment on the article.
The world's second biggest miner by market capitalization had been seeking financing for Simandou, even after a $1.1 billion writedown on the project in February. Last month the Anglo-Australian company submitted a feasibility study to the Guinean government.
But global oversupply of iron ore made the project inviable at this time, Jacques told The Times.
Simandou would have comprised an iron ore mine in central Guinea, a 650-kilometer (404-mile) railway and a deepwater port on the West African country's Atlantic Coast.
At full production, Rio said the project would generate about $7.5 billion in revenues, according to a 2014 report, and add $5.6 billion to Guinea's GDP, making Guinea the fastest growing economy in the world.
The country's ministry of mines said in a statement on Monday that it plans to pursue the project despite Rio Tinto's decision.
"Despite the challenge of financing the project, we believe that a financing solution will be found with partners who share our long-term perspective," it said.
