Jetti has two commercial operations in the Americas where its technology is being applied to millions of tons of ore.  

Pinto Valley started producing copper cathode in 1981, but output had declined by about 75% due to the chalcopyrite passivation layer preventing leaching from occurring. 

In 2019, Jetti deployed its technology on the mine’s historic dump leach operation. Jetti doubled copper cathode production per area irrigated at Pinto Valley in less than one year.

Capstone Copper then extended its use of Jetti’s technology through an innovative optimization program (PV3) and further expansion opportunities are now being considered. 

Jetti has commenced operations at its second commercial deployment with a major global mining company in the second half of 2022.
