Exploration and Definition Drilling Commences at Plomosas

Infill drilling of high grade SOX mineralisation to upgrade JORC Resource for commencement of mining

Consolidated Zinc Limited (ASX: CZL or “the Company”) is pleased to announce that exploration and delineation drilling has recommenced at its Plomosas project.

Semi-Oxide Ore (SOX)

A six hole program has commenced drilling with the objective to extend the Indicated JORC Resource (Resource) envelope down dip and to the south. These holes are targeted within the existing Inferred Resource envelope and will infill the identified mineralisation.

Drilling aims to convert SOX Inferred category Resources to Indicated Resources in preparation for mine planning and commencement of mining. This drilling will be complemented with ore strike drive sampling along the 913mRL, 900mRL and the 907mRL ore strike drives. These samples will effectively cover the defined mineralisation in the central zone. Figures 930L one and two, shows the location of these samples and drilling traces of previous drill holes as previously reported to the ASX.

Drill intersections near to the extension and previously reported to the ASX on 21 March 2016 include:

LV7DD003; 2.90m @ 34.52% Zn, 14.95% Pb, 90.0 g/t Ag from 50.6 metres down hole (“mdh”) and 0.95m @ 29.10% Zn, 11.50% Pb, 61.3 g/t Ag from 56.9 mdh; and
LV7DD007; 2.65m @ 18.42% Zn, 10.12% Pb, 60.8 g/t Ag from 71.60 mdh

Tres Amigos Resource extension.

A total of seven holes have been planned for future drilling to test the mineralisation around hole LV5040 and LV5054. These holes intersected a similar style of mineralisation to that of the Tres Amigos zone, 140 metres to the north which were drilled in 2018 during the last period of the campaign LV5040 and LV5054 are located below Level 9 in a plunging high-grade zone, hosted in the Juarez Limestone Unit.

Details of the previous drilling results were announced to the ASX for hole LV5040 on 14 February 2018 and on 5 April 2018 for hole LV5054 and include respectively:

LV5040; 4.50m @ 36.50% Zn, 0.76% Pb, 9.27g/t Ag from 164.05 mdh and 1.0m @ 35.01% Zn, 0.97% Pb, 7.00g/t Ag from 176.05 mdh; and
LV5054; 3.1m @ 18.80% Zn, 1.25% Pb, 13.22g/t Ag from 149.45 mdh.

These holes intersected the deepest known economic mineralisation in Plomosas to date. The current drilling program is designed to also upgrade the Resource to Indicated status and add significant value to the project.

Drilling updates will be announced as results come to hand.

ABOUT CONSOLIDATED ZINC

Consolidated Zinc Limited (ASX: CZL) owns 100% of the historic Plomosas Mine, located 120km from Chihuahua City, Chihuahua State, Mexico. Chihuahua State has a strong mining sector with other large base and precious metal projects in operation within the state. Historical mining at Plomosas between 1945 and 1974 extracted over 2 million tonnes of ore grading 22% Zn+Pb and over 80g/t Ag. Only small-scale mining continued to the present day and the mineralised zones remain open at depth and along strike.

The company has recommenced mining at Plomosas and is committed to exploit the potential of the high-grade Zinc, Lead and Silver Mineral Resource through the identification, exploration and exploitation of new zones of mineralisation within and adjacent to the known mineralisation with a view to identify new mineral resources that are exploitable.

Competent Person Statement:

The information in this report that relates to exploration results, data collection and geological interpretation is based on information compiled by Mr Steve Boda BSc (Hons), MAIG, MGSA, MSEG and Mr Andrew Richards BSc (Hons), Dip Ed, MAusIMM, MAIG, MSEG, GAICD. Mr Boda and Richards are both Members of Australian Institute of Geoscientists (AIG) and Mr Richards is also a Member of the Australasian Institute of Mining and Metallurgy (AusIMM).

Both Mr Boda and Richards have sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity that is being undertaken to qualify as Competent Person as defined in the 2012 edition of the ‘Australasian Code for Reporting of Exploration Results, Minerals Resources and Ore Reserves’ (JORC Code). Mr Boda and Richards consent to the inclusion in the report of the matters based on their information in the form and context in which it appears.

The information in this report that relates to Mineral Resources is based on, and fairly represents information and supporting documentation prepared by Mr Andrew Richards, a Competent Person who is a Member of the Australasian Institute of Mining and Metallurgy and Member of the Australian Institute of Geoscientists.
