Zacatecas Silver Corp. announced it has completed first pass geological mapping of the San Manuel Vein System. The San Manuel vein system lies immediately to the west of the San Gill Breccia System which was the focus of the company news release dated April 19, 2021. The San Manuel vein system is in the southern part of the Zacatecas Property. The veins at San Manuel are generally oriented northeast-southwest -- the typical orientation of silver-base metal intermediate sulphidation veins throughout the Zacatecas region. Veins roll towards an east-west orientation where they contact the north-south San Gill breccia. Reconnaissance mapping has confirmed the presence of multiple steeply dipping veins. Historical artisanal workings and shafts are common within this area, suggesting historic mining despite limited to no drilling. Veins at San Manuel are pervasively oxidized and often weather recessively suggesting a quartz-poor but silver-base metal rich mineralogy. Once oxidized such veins are unlikely to outcrop at surface, but rather weather recessively. Although this makes mapping of vein extensions more challenging, it also offers the potential for discovery of previously un-recognized veins. Zacatecas is currently reinterpreting the historical soil, rock-chip and channel sampling assays results to better model vein distribution and focus further sampling. Zacatecas has now completed land access agreements with two of the main landowners at San Gill and is in discussion with the third. The Company has already commenced an environmental study at San Gill-San Manuel, concurrent with planning of first phase drilling at this target, which should be completed within 4 weeks. In addition to the work completed at San Gill-San Manuel, Zacatecas announced that it has now signed three to five year land access agreements with the community, the municipality and all private land-holders at Panuco. These agreements, now complete, allow for ongoing exploration and drilling. The Company has also completed its environmental study at Panuco and has submitted the report to SEMARNET as the final stage of drill permitting.
