Located in the Patagonia Mountains, about 80 kilometres south-east of Tucson, Arizona, Hermosa comprises the zinc-lead-silver Taylor sulphide deposit (Taylor Deposit), and the zinc-manganese-silver Clark oxide deposit (Clark Deposit). In addition to the Taylor and Clark deposits, Hermosa has a highly prospective broader land package, which includes the copper-lead-zinc-silver Peake exploration target, as well as the Flux prospect.
Strongly complementing our existing portfolio, Hermosa provides the opportunity to leverage the underground mining and processing methods we've used at our Cannington operation in Queensland, Australia.
Our work at Hermosa is helping to fulfill our strategy by reshaping our portfolio to produce the metals that are critical for a low-carbon future.
Hermosa is being designed as our first ‘next generation mine’, using automation and technology to minimise our impact on the environment and in line with our goal of achieving net zero operational carbon emissions by 2050.
Our work to date has confirmed the potential for the Clark Deposit to produce battery-grade manganese for the growing North American electric vehicle supply chain, with zinc and silver co-products.
We’re also unlocking value through the exploration of our regional scale land package. We have identified a highly prospective corridor which will be prioritised for future drilling.
A metal increasingly in demand for batteries that store wind and solar energy and widely used for galvanising iron and steel to protect against corrosion. It’s long been used in construction because of its special properties.
A metal in high demand that is increasingly used in EV battery chemistries and to improve the quality and strength of steel in major infrastructure such as hospitals, office towers and bridges.
We recognise the value of working with experts to help achieve our sustainability commitment across our operations and projects. At the Hermosa project, safe and sustainable underground exploration will require moving groundwater away from the orebodies. This will be accomplished by pumping groundwater away from the orebodies and returning it to the neighboring environment after treating it to the highest applicable water quality standards.
