The two Chinese companies plan to set up a joint venture to work on the first stage of the mine, which also contains copper, cobalt and gold reserves, an HBIS Resources filing to the Shenzhen Stock Exchange showed.
The scope of cooperation includes mine and port construction and operation, it added. No value was put on the framework agreement, which was signed on July 31 and will serve as a basis for negotiations between the two firms.
Investing in Peru, the world's second-biggest copper producer after neighbouring Chile, would be HBIS' first foray into South America. It coincides with steady demand from Chinese steel mills as prices of iron ore, the main steel-making ingredient, top $100 a tonne.
Qingdao-based Zhongrong Xinda acquired the rights to Pampa de Pongo in 2016 and its subsidiary Jinzhao Mining Peru is the project's operator.
A portfolio published by Peru's Ministry of Energy and Mines in October 2018 said Pampa de Pongo, in the Arequipa region, could produce 28.1 million tonnes of iron per year and was expected to start operations in 2023.
It put the investment required at $2.2 billion.
Peru in mid-March imposed a mining lockdown to curb the spread of the new coronavirus, but has since eased restrictions. The country has reported more than 400,000 confirmed coronavirus cases and more than 18,000 deaths from COVID-19, the respiratory disease the virus causes.
