Alta Zinc Limited (Alta or the Company) announced the results of four drill holes (PBD02 to PBD05) from its on-going diamond drilling campaign in the Pian Bracca Zone. All holes were drilled upwards from the initial drill pad in the east-central part of the zone. All holes analysed to date have intersected significant zinc and lead mineralisation. While not the focus of the current campaign, drilling has clearly demonstrated the continuity and high-grade nature of a second layer of mineralisation (Breno) which lies approximately 20m below the Pian Bracca Zone. This style of mineralisation was mined historically at the Gorno Project. Significantly, a third zone of mineralisation has been intersected above the Pian Bracca thrust in an area previously thought to be barren. This clearly illustrates the untapped geological potential of the Gorno Project area. The drilling has so far been focussed on defining the mineralisation and geology present in the east-central portion of the Pian Bracca Zone. Figure 1 is a long-section outlining the location of the current drilling and the untested extent of the Pian Bracca Zone where future drilling is planned for this campaign. Drilling is currently progressing on budget and schedule. It is anticipated that the next batch of core will be shipped for assay in early February with results expected in the second half of February. This phase of drilling campaign is expected to continue until the end of the second quarter 2020.
