VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 20, 2016) - Alianza Minerals Ltd. (TSX VENTURE:ANZ) ("Alianza" or the "Company") is pleased to announce the results of fieldwork at the wholly-owned Isy silver-gold property in the Ayacucho Department, Peru. The 2016 work program was undertaken to provide geological context to silver and gold mineralization associated with epithermal-style veins and alteration identified in 2010 and 2011 reconnaissance work. The program was successful in:
- Identification of a 2.7 kilometre (km) long corridor of discontinuous/anastomosing veining at the Jello Orcco target. This trend remains open along trend and the longest vein mapped to date is 500 metres (m) in length.
- Confirming that veins are high level and low temperature as interpreted from alteration clay mineralogy and indicator metal suite geochemistry, suggesting productive (gold-silver) portion of the epithermal system may be preserved at depth.
- Determining that the Patacancha and Jello Orcco occurrences may be related as mapping indicates they may occur within the same structural trend.
- Building relationships with local communities to support future exploration activities.
"We are encouraged by the results of our field program at Isy," stated Jason Weber, President and CEO of Alianza. "The breadth and extent of veining may indicate the system has considerable size and the pathfinder element geochemistry and clay alteration mineralogy suggest that we may be sampling the upper or distal portions of a large epithermal system. The next phase of work will seek targets at depth where the productive portion of the system may be preserved."
The 2016 program was undertaken to augment previous work which consisted of prospecting and rock sampling in 2010 and 2011. This earlier work identified veins anomalous in silver and gold with highly anomalous epithermal-suite metals at the Patacancha and Jello Orcco targets. The 2016 program focused on geological and structural mapping of the property at 1:10,000 scale with detailed 1:2,000 scale mapping in the Jello Orcco area. Additional geochemical soil and rock sampling was completed in conjunction with the mapping program. A total of 114 samples were submitted for analyses, including 21 soil samples, 88 rock samples and 5 control standards.
At the Jello Orcco target, exploration work resulted in the identification of multiple sets of banded, brecciated and massive silica veins generally 0.4 to 1.5 metres in width (maximum 9 metres) over a 2.7 km open-ended trend. Veining is hosted within ash, lapilli and andesite flow volcanic rocks and veins contain silica> kaolinite>barite>alunite> goethite>pyrite. The longest vein mapped is approximately 500 metres in length. Vein samples are elevated in arsenic, mercury and antimony with silver and gold showing the strongest relationship to mercury. This geochemical signature and clay alteration assemblage (verified by X-Ray Diffraction analysis) indicates that veining at surface is high level and likely represents the upper portions of a large epithermal system. Future programs at the Jello Orcco target will focus on identifying gold and silver mineralization at depth.
The Patacancha target is a 250 metre by 400 metre area of locally vuggy massive silica, brecciated silica and stockwork silica veinlets. Samples anomalous in silver and gold are elevated in mercury, arsenic and antimony. Detailed structural mapping indicates that the Patacancha target may be related to the Jello Orcco target, approximately two kilometres to the south. Further work will be necessary to determine the relationship between the two target areas.
Isy is located 110 kilometres east of Ica, Peru and is accessible by paved road. It is wholly-owned and available for option. Maps and photos of the property are available on the Company's website at www.alianzaminerals.com/project/isy-prospect/. Management will be seeking a partner to continue exploration of the Isy Property.
