• High grade zinc in Tres Amigos North area confirmed in holes LV5016 and LV5018;
• Final assay results returned grades over intercepts of 1.5m @ 26.92% Zn+Pb, 52.05g/t Ag and 1.85m @ 32.88% Zn+Pb, 11.07g/t Ag
• Confirms potential for repetitions of ore grade mineralisation associated with the Juarez Limestone;
• Drilling is ongoing to determine the scope and geometry of the mineralisation.

Consolidated Zinc Limited (ASX:CZL) is pleased to confirm the final assay results of the high grade zinc and lead mineralisation intersected in the Company’s initial six drillholes completed at the recently identified Tres Amigos North (TRN) zone (LV5013 to LV5018). This zone is found in the immediate hanging wall to the Juarez Limestone Unit and sits outside of the current high grade JORC resource envelope (Figure 1).

As previously reported, several samples from within wider intersections returned grades higher than 30% for zinc which exceeded the upper limit of the analytical methods. These had to be reassayed by a more suitable method to finalise the grades of the mineralised intercept.

Tables 1 and 2 summarise the hole details and final assay results for which the finalised intercepts are:

• LV5016 1.50m at 26.33% Zn, 0.59% Pb, 52.05 g/t Ag
• LV5018 1.85m at 32.60%Zn, 0.28% Pb, 11.07 g/t Ag

The TRN area represents an exciting opportunity for the Company as it is a previously untested and unmined horizon stratigraphically below the mineralised Mina Vieja Manto. As reported to the market on 30 April 2017, high grade face sampling results are located in an area that is immediately accessible by existing workings (Figures 3, 4).

Mineralisation here comprises coarser grained sphalerite and lesser galena than the mineralisation related to the Mina Vieja Manto and in some ways is similar to the mineralisation intersected in hole TRSDD010, located 500m to the south, near Mina Vieja Mine (Figures 2a and 2b). Mineralogy of TRN, suggests it is a higher temperature replacement style, commonly containing late-stage pyrite overprints, which occur patchy and irregular. There is a structural complexity associated with the mineralisation at TRN, which includes tight isoclinal folding of the mineralisation, shear structures and a change in the strike orientation of mineralisation to east-west.

The position of hole LV5018 and the mineralisation it intersected suggests a down-dip continuation of the mineralisation defined by the Tres Amigos resource envelope, as shown in Figure 6 and is estimated to be 140 metres in length. This area will be further drill tested for additional extensions of mineralisation which will assist CZL in modelling the nature of mineralisation in this area and in drill targeting.

Work will continue to update and improve the geological setting and the relationship to the Tres Amigos main zone. This includes, drilling of the TRN mineralisation to scope out the extent and the geometry of the mineralisation over the next period subject to ongoing drilling results. 

ABOUT CONSOLIDATED ZINC

Consolidated Zinc Limited (ASX:CZL) is a minerals exploration company listed on the Australian Securities Exchange. The Company’s major focus is in Mexico where it recently acquired 51% of the exciting high grade Plomosas Zinc Lead Silver Project through its majority owned subsidiary, Minera Latin American Zinc CV SAPI. 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’s main focus is to identify and explore new zones of mineralisation within and adjacent to the known mineralisation at Plomosas with a view to identifying new mineral resources that are exploitable.
