Brownfield exploration in CZL’s Juarez mine in Mexico identifies new ore horizons

Posted on 4 Dec 2017
Consolidated Zinc Ltd (CZL) has announced high grade rock chip results from the first systematic mapping undertaken at Juarez mine in Mexico, as part of the ongoing near mine exploration program. Additional high grade results from the regional exploration program, particularly the Alfonsitos prospect, have also been returned and continue to support the prospectivity of this area.
The Juarez mine is located approximately 550 m northwest of the Plomosas plant site with easy access from the portal to the mine by road. The mine development remains geotechnically sound, with the majority of the drives and
stopes occurring within the competent Juarez limestone unit. Mining was previously undertaken by ASARCO with
approximately 77,000 t of high grade ore estimated to have been removed. No systematic exploration was completed. This mining was by long hole stoping, resulting in large pillars being left behind, however, the stopes were long and narrow, following the trend of mineralisation.
Recent mapping by CZL has identified several massive sulphide horizons exposed underground. Assay results from the southern end include a sample of fault gouge from a massive and brecciated limestone contact grading 28.47% Zn, 14.25% Pb and 52.6 g/t Ag. Further work in the area will include continual cleaning of the Juarez mine drives, for location of UG drilling stations; continuation of UG mapping at the Juarez mine; interpretation of the structures and relevance to mineralisation; and generation of drill targets.
