Almaden Confirms New Zone of High-Grade Mineralisation Within PFS Pit, Hits 1.00m of 237.00 g/t Gold Plus 232.0 g/t Silver Within 38.60m of 7.92 g/t Gold and 14.9 g/t Silver (Uncut)

VANCOUVER, BC--(Marketwired - November 21, 2017) - Almaden Minerals Ltd. ("Almaden" or "the Company") (TSX: AMM) (NYSE MKT: AAU) (NYSE American: AAU) is pleased to announce new assay results from Almaden's ongoing exploration and development program at the Company's Tuligtic project, Mexico. One drill rig is focused on step-out exploration drilling outside of the established resource area, while the second drill rig has completed holes for metallurgical samples related to the ongoing Feasibility Study, and is now testing new zones within the Pre-Feasibililty Study ("PFS") pit. Today's results are from holes TU-17-518 and 520 which were drilled to follow-up hole TU-17-504 (announced August 23, 2017) that intersected new and significant mineralisation in an upper portion of the PFS pit which was modelled as waste material in the Company's PFS. Holes TU-17-518 and 520 confirm this discovery of a new zone of mineralisation in volcanic and limestone. Highlights include the following intercepts:

Hole TU-17-518    SECTION 10+650 EAST Az. 150, Dip -57
23.00 meters @ 0.45 g/t Au and 1.0 g/t Ag
38.60 meters @ 7.92 g/t Au (2.84 g/t with 1 sample cut(1)) and 14.9 g/t Ag
Including	23.50 meters @ 12.70 g/t Au (4.36 g/t with 1 sample cut(1)) and 20.7 g/t Ag
And	5.00 meters @ 51.45 g/t Au (12.25 with 1 sample cut(1)) and 58.4 g/t Ag
And	1.00 meters @ 237.00 g/t Au and 232.0 g/t Ag

gold assays over 41 g/t were cut to 41 g/t.

Hole TU-17-520    SECTION 10+675 EAST Az. 150, Dip -70
20.40 meters @ 0.89 g/t Au and 11.1 g/t Ag
Including	7.00 meters @ 2.07 g/t Au and 20.4 g/t Ag

J.D. Poliquin, chairman of Almaden stated, "These results again show the potential of the Ixtaca gold silver deposit to grow. As I have stated before, while Ixtaca is a prominent new discovery of gold and silver reserves, we are clearly only at the beginning of the discovery cycle at this project. We have a two-pronged approach. On the one hand we are focussed on developing the Ixtaca deposit into a significant precious metals producer in Mexico, and engineering work and studies on a Feasibility Study are progressing well. At the same time we have in front of us the opportunity for additional discovery and resource growth. We are at the top of a fully preserved epithermal system and over the next several months exploration drilling will also test for additional vein zones beneath alteration elsewhere on the project."
