History and location

In August 2018 we completed the acquisition of Hermosa in the Patagonia Mountains, about 80 kilometres south-east of Tucson, Arizona. Hermosa comprises two major mineral deposits, Taylor and Clark.

Hermosa strongly complements our existing portfolio and provides the opportunity to leverage the underground mining and processing methods we've used at our Cannington operation in Queensland, Australia.

Recently, we carried out the first blast at the twin exploration declines to welcome in an exciting new phase of development which will allow us to drill test extensions and enhance our understanding of the Project's existing high-grade resource.

The milestone comes as we work towards further optimising the design and development of Hermosa.

Beneath the surface

The Taylor deposit is a greenfield development option that has a reported resource of 155 million tonnes, averaging 3.39% zinc, 3.67% lead and 69 g/t silver. The resource remains open at depth and laterally, with multiple targets to be tested as we continue our extensive surface drilling program.
