PERTH (miningweekly.com) – Junior Consolidated Zinc has reported a 70% increase in the zinc resource at its Plomosas zinc/lead/silver project, in Mexico.
The project is estimated to contain a resource of some 968 000 t, grading 15.9% zinc and lead for 154 000 t of contained metal.
Consolidated Zinc on Monday reported that the additional mineral resource came from extensions both down dip and down plunge of the existing mine development, and the extrapolation of in-mine mineralisation.
“This resource increase is another step along the path we initially outlined with our objective to identify a viable resource for short-term cash flow,” said Consolidated Zinc MD Will Dix.
“Tres Amigos is shaping up really well and the excellent metallurgical results support this. The Carola South and Las Espadas areas are underexplored and we plan to target them for the next resource update in 2018.”
Dix said that, in the meantime, the company’s focus would be on completing a scoping study for the Plomosas project and reviewing its options for the restart of mining operations, using the on-site plant and underground infrastructure.
The Plomosas mine was active between 1945 and 1974, and extracted some two-million tonnes of ore grading 22% zinc and lead, and over 80 g/t of silver.
