Highlander Silver Corp. Provides Update on Exploration Program at Alta Victoria
Highlander Silver Corp. provided an update on its ongoing exploration program at its Alta Victoria silver-polymetallic project (the "Project") in central Peru. The Project is located 160 kilometers northeast of Lima and consists of 18 mining concessions over a total area of 71 km within the Central Cordillera Polymetallic Mineral Belt, which hosts major scale silver and polymetallic mineral deposits. The district has produced over 1.5B oz Ag historically from carbonate replacement deposits, skarn, vein, manto, and diatreme related deposits. Five major mines (Uchucchacua, Santander, Chungar, Iscaycruz and Casapalca) lie along and/or adjacent to the Alpamarca Fault to the NW and SE of the Project. Concessions controlled by Highlander straddle nearly 14 km of the Alpamarca/Chonta Fault at the heart of this district. Note that information regarding adjacent properties is not necessarily indicative of the mineralization of the Company's properties. The Project hosts silver-rich polymetallic mineralization in a mid-late Cretaceous sequence of siliclastic and overlying carbonate sedimentary rocks. Mineralization exposed at surface and in underground mining extends over an area of approximately 4 km x 1 km. Styles of mineralization include stratabound mantos and replacements, high angle veins, breccias and irregular replacement bodies. Two target areas, referred to as Pachas and Santa Teresita, emerged from the results of multiple generations of surface work from different companies, including Pan American Silver Corp., Glencore plc, Solitario Zinc Corp. and Minera Sociedad Corona S.A., beginning in 2007. The Company commenced exploration of the Project in 2017. Initial exploration included surface geologic mapping, systematic sampling, magnetics and IP geophysical surveys as well as sampling and inspection of historic, small scale underground mine workings. Historic mining on the property dates back to the 1970´s. In the Panchas area, prospects include the Victoria Mine, Adriana North, Adriana East, Buenas Estrellas and the Sanguinetti mine. Sampling in and around these prospects has returned high-grade gold and base metal mineralization suggesting a proximal intrusive source. Multiple chip and grab samples have returned grades of up to 6.2 g/t Au, 4,800 g/t Ag, 0.64% Cu, 18.7% Pb, 30.1% Zn and 0.14% Mo. The Victoria Mine was worked up until 2018, having produced 1,500 tonnes at an average grade of approximately 10 opt Ag (311 g/t), 10% Pb. At Santa Teresita, moderate to high-grade Au-Ag and base metal mineralization is hosted by brecciated sandstones. Mineralization occurs in a 400m diameter area defined by surface soil and rock sampling, centered on a structural intersection located on the NNW trending ridge of Cerro Pucara. Here a 20 centimetre quartz-galena-barite vein returned 9.6 g/t Au, 2,230 g/t Ag, 0.3% Cu, 9.5% Pb and 2.3% Zn. Santa Teresita is considered to be a distal, manganese rich, precious metals prospect. In the fourth-quarter of 2020, the Company completed a 2,300 metre, seven diamond drill hole, scout drilling program. Six of the seven drill holes were collared in the Santa Teresita area while one hole was drilled to test the depth extension of the Sanguinetti Mine mineralization, part of the Pachas area. Ongoing exploration is focusing on detailed work to better define potential targets in the Pachas and Santa Teresita Areas. In parallel, steps are being taken to cover more of the concession block on a reconnaissance level aimed at generating additional areas of interest and potential drill targets.
