 VANCOUVER, British Columbia, Oct. 27, 2020 GLOBE NEWSWIRE -- Almaden Minerals Ltd. Almaden or the Company; TSX : AMM ; NYSE American : AAU is pleased to announce that a field geology exploration program is now underway in the Companys property surrounding the area of the Ixtaca project. In the past the Company developed a geologic and exploration model for the Ixtaca deposit and region. The Ixtaca deposit occurs in both young volcanic rocks and underlying carbonate sedimentary rocks. The bulk of the known Ixtaca deposit epithermal veins are hosted by the underlying sedimentary rocks while the overlying volcanic unit is widely altered to clay minerals, which is typical of the upper part of an epithermal vein system.
