VANCOUVER, British Columbia, Nov. 05, 2020 (GLOBE NEWSWIRE) --
Almaden Minerals Ltd. (“Almaden” or “the Company”; TSX
is pleased to announce additional results of its ongoing review of exploration targets which lie outside the currently defined reserve envelope of the Ixtaca deposit (See Figure 1, Exploration Targets).
The Main Ixtaca Zone of the Ixtaca deposit is hosted by limestone where the veins form a wide zone of veining referred to as a vein swarm. This vein swarm in limestone has been the primary focus of the Company’s exploration efforts to date and the Feasibility Study level technical examination of the Ixtaca deposit (see “About the Ixtaca Deposit”, below).
Adjacent to the Main Ixtaca Zone, shaley carbonate rocks host the more discrete focussed gold-silver vein related mineralisation of the Northeast Extension Zone, which also has higher associated zinc and lead values. Based on structural interpretation, the Main Ixtaca Zone gold-silver vein swarm could be the upper part of a vein system which transitions at depth to structurally controlled silver-lead-zinc dominated mineralisation where the Northeast Extension Zone would project down dip underneath the Main Ixtaca Zone (see Figure 2, Longitudinal Section of Main Ixtaca Zone and Cross Section of Northeast Extension Zone). This potential for metal zonation from upper gold-silver to deep silver-lead-zinc mineralisation is supported by geologic interpretation, geologic models for epithermal precious metal deposits and observations made in other epithermal vein deposits in Mexico.
Drilling to depth beneath the Ixtaca Main Zone will be a priority in a future drilling program currently being planned by the Company.
About the Ixtaca Deposit
Since discovery with the first drill hole, exploration work at Ixtaca has been almost entirely focused on the discovery area, and this work has led to the silver and gold reserve which underpins the feasibility study (“FS”), results of which were announced in December, 2018 1 .
The highlights of the FS, using base case prices of US$1275/oz gold and US$17/oz silver unless noted otherwise, include the following (all US dollars):
- Average annual production of 7.06 million ounces silver and 108,500 ounces gold (15.2 million silver equivalent ounces, or 203,000 gold equivalent ounces) 2 over the first 6 years;
- After-tax IRR of 42% and after-tax payback period of 1.9 years;
- After-tax NPV of US$310 million at a 5% discount rate;
- After-tax IRR of 57% at the highest upper case price deck of US$1425/oz Au and US$20/oz Ag;
- After-tax NPV (5%) of US$466 million at the highest upper case price deck of US$1425/oz Au and US$20/oz Ag;
- Initial Capital of US$174 million;
- Average annual production of 6.14 million ounces silver and 90,800 ounces gold (12.9 million silver equivalent ounces, or 173,000 gold equivalent ounces) over an 11 year mine life;
- All-in Sustaining Costs (“AISC”), including operating costs, sustaining capital, expansion capital, private and public royalties, refining and transport, of US$11.30 per silver equivalent ounce, or US$850 per gold equivalent ounce;
Elimination of tailings dam by using filtered tailings, which reduces the project footprint and water usage. Construction of a water reservoir providing a permanent and consistent long-term supply of water for residents.

While it awaits the outcome of its permitting application and related processes (see press releases of February 27, 2020 and September 9, 2020), the Company is proceeding with exploration at this large property with a focus on some previously identified high potential targets which lie outside of the current reserve as defined in the FS.
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.
