Almaden Announces Pathfinder Elements Validate SE Alteration Zone Potential for Epithermal Veining
VANCOUVER, British Columbia, Nov. 25, 2020 (GLOBE NEWSWIRE) — Almaden Minerals Ltd. (“Almaden” or “the Company”; TSX: AMM; NYSE American: AAU) is pleased to report the results of initial surface sampling of the veins discovered in the Southeast (“SE”) Alteration Zone of the Ixtaca Project.
As announced on November 18th, the Company discovered several areas of veining cropping out within the SE Alteration Zone of the Ixtaca Project while mapping promising clay alteration in the area.
Seventeen samples of the veining were collected and submitted for analysis to ALS Global in Zacatecas, Mexico. All but one sample returned below detection gold and silver, with the exception returning a value of 62 ppb gold. However, even though the outcrops are leached and weathered, many of the samples also returned elevated values for epithermal pathfinder elements which are commonly found in the higher parts of epithermal alteration zones.
Morgan J. Poliquin, President and CEO of Almaden, stated “The presence of pathfinder elements in these samples is very encouraging as it corroborates our view that the SE Alteration Zone could represent the higher levels of a potential underlying epithermal system. It is quite typical that the higher parts of these systems contain negligible precious metals values. We look forward to continued mapping, and eventually drilling, in this area.”
About the SE Alteration Zone
The Ixtaca deposit occurs in both the overlying volcanic rocks and the older underlying carbonate sedimentary rocks. The bulk of the gold and silver bearing epithermal veins comprising the Ixtaca deposit are hosted by the underlying sedimentary rocks, while the overlying volcanic unit is typically mineralized at its base and clay altered above. This alteration appears to extend to the southeast of the Ixtaca deposit area where a topographic high exposes a section of the overlying volcanic rocks with significant clay alteration in an area measuring about 1.5 kilometre (km) east-west by 1 km north-south, which is referred to as the SE Alteration Zone, which is centred approximately 1km south east of the Ixtaca deposit.
The SE Alteration Zone comprises white argillic (clay-altered) volcanics and, most interestingly, clusters of anomalies identified from a hyperspectral survey that include the spectral signatures of important epithermal alteration minerals such as kaolinite, alunite and buddingtonite. The Company believes that there is significant potential for the discovery of a new zone of epithermal mineralization in the sedimentary rocks beneath the SE Alteration Zone and possibly at other similar anomalies in the area.
Any mineralization found within the SE Alteration Zone would represent a new discovery as this area lies well outside of the current Ixtaca deposit resource area, which was the focus of a Feasibility Study (results of which were announced by the Company in December, 2018), and 2019 environmental permit application. A report titled “Ixtaca Gold-Silver Project, Puebla State, Mexico NI 43-101 Technical Report on the Feasibility Study”, which was prepared in accordance with NI 43-101, is available under the Company’s profile on SEDAR and on the Company’s website.
Exploration Opportunities
The Ixtaca deposit is one of several exploration targets on the Company’s mineral claims, which cover an area of high-level epithermal clay alteration. The project area is partially covered by volcanic ash deposits which mask underlying alteration, potential vein zones and associated soil responses. In areas devoid of this covering ash soil sampling has defined several distinct zones of elevated gold and silver values and trace elements typically associated with epithermal vein systems. The Ixtaca zone is one of the largest areas of gold/silver soil response but it is also one of the areas with the least ash cover on the project.
Management believes that the other altered and geochemically anomalous areas could represent additional zones of underlying quartz-carbonate epithermal veining like the Ixtaca zone. The potential quantity and grade of these exploration targets is conceptual in nature. There has been insufficient exploration and/or study to define these exploration targets as a Mineral Resource. It is uncertain if additional exploration will result in these exploration targets being delineated as a Mineral Resource. The potential quantity and grade of these exploration targets has not been used in this Study.
