Jetti Resources has reached an agreement with Sociedad Contractual Minera El Abra and Freeport-McMoRan to deploy Jetti’s leaching technology at the El Abra copper mine in Chile, majority-owned and operated by Freeport.

The use of Jetti’s technology will enable El Abra to produce more copper while taking advantage of existing infrastructure and will generate strong financial returns, according to Jetti.

This is not the first Freeport installation for Jetti, with a spokesperson for the mining company recently confirming to IM it was trialling the technology through “a commercial installation” at its Bagdad mine in Arizona, USA.

Jetti’s catalytic technology will be deployed on the existing leach stockpiles at El Abra and will target over 20 MIb/y (9,072 t/y) of incremental copper cathode production after an initial ramp-up period. The project will leverage existing El Abra infrastructure including excess tankhouse capacity sufficient to process all production from Jetti’s leaching technology. Engineering work for the establishment of Jetti’s on-site catalyst facility is already well advanced, with construction expected to commence in the first half of 2023 and commissioning expected in the second half of the year, Jetti said.

El Abra is an open-pit copper mining complex with a large sulphide resource as well as an established leaching operation. In 2022, El Abra produced approximately 200 MIb of copper.

Mike Outwin, CEO and Co-Founder of Jetti Resources, said: “El Abra is Jetti’s first deployment in Chile, and we are delighted to extend our partnership with Freeport to a second site. Real momentum is building behind the deployment of Jetti’s technology as its unique technological, commercial and environmental benefits become increasingly clear. We look forward to working with Freeport to successfully unlock profitable new pounds of copper with a low carbon footprint and with reduced water consumption.”
