Vancouver, British Columbia--(Newsfile Corp. - October 29, 2024) - First Andes Silver Ltd. (TSXV: FAS) (OTC Pink: MSLVF) (FSE: 9TZ0) (the "Company" or "First Andes") is pleased to announce multiple high-grade silver assays from its recently completed maiden diamond drill program at the Santas Gloria silver property, located in Peru.

Highlights:

• Significant silver assays include:
  • 7.43m at 224 g/t AgEq (193 g/t Ag, 0.34% Pb, 0.3% Zn, 0.05 g/t Au) from 86.70m including 0.95m at 754 g/t AgEq (701 g/t Ag, 1.07% Pb, 0.62% Zn, 0.08 g/t Au) and 1.23m at 387 g/t AgEq (356 g/t Ag, 0.34% Pb, 0.39% Zn, 0.12 g/t Au) (San Jorge vein system)
  • 3.10m at 155 g/t AgEq (138 g/t Ag, 0.18% Pb, 0.17% Zn, 0.08 g/t Au) from 47.30m (San Jorge vein system)
  • 6.40m at 108 g/t AgEq (70 g/t Ag, 0.40% Pb, 0.78% Zn, 0.05 g/t Au) from 138.8m including 2.26m at 162m AgEq (103 g/t ag, 0.59% Pb, 1.34% Zn, 0.03 g/t Au) (San Jorge vein system)
  • 4.40m at 134 g/t AgEq (80 g/t Ag, 0.16% Pb, 0.34% Zn, 0.44 g/t Au) from 42.70m (Maribel vein system)
  • 3.30m at 110 g/t AgEq (65 g/t Ag, 0.15% Pb, 0.43% Zn, 0.31 g/t Au) from 35.40m including 0.48 m at 391 g/t AgEq (310 g/t Ag, 0.02% Pb, 0.02% Zn, 0.89 g/t Au) (Paquita vein system)
  • 0.87m at 131 g/t AgEq (72.4 g/t Ag, 0.71% Pb, 1.19% Zn, 0.05 g/t Au) from 115.30m including 0.42m at 224.3 g/t AgEq (127 g/t Ag, 1.25% Pb, 2.0% Zn, 0.04 g/t Au)
    
    
• Silver grades were reported on all drilled vein systems, being San Jorge, Tembladera, Paquita and Maribel.
  
  
• Program focused on oxidized portion of intermediate epidermal sulphidation system with follow up drilling to occur at depth in sulphide zone of vein systems.

Dr. Christopher Wilson, PhD, consulting geologist for First Andes, stated, "The drill results are very encouraging with 11 of 12 holes reporting significant silver grades. Except for one hole, all holes were drilled into the oxide portion of the veins and reported intercepts between 30 - 80m from surface. Silver equivalent grades and widths are considered significant as the upper oxidized parts of the veins have been extensively leached of their metal endowment. The assay results from oxidized intercepts confirm that the veins are silver-base metal mineralized. Hole SG003 intercepted a partially oxidized sulphide-quartz vein at a vertical depth of approximately 60 m. This intercept returned our highest-grade silver result and is more consistent with the high grades reported by the companies previous channel sampling of limited underground workings. The Company's next step will be to prepare a more significant drill program to pursue high-grade silver in the sulphide zones identified by the oxides results from the latest drill program."

Mineralization at the Santas Gloria silver property is of an intermediate suplidation epithermal type, with multiple vein systems over several kilometers. Prior to First Andes' maiden drill program, Santas Gloria has never been drill tested, despite over 12 kilometers of multi-phase veins mapped at surface.

San Jorge Vein System Results:

At the San Jorge vein system, a total of seven diamond drill holes were completed for a total of 733.5 meters. Except for hole SG003, all holes intercepted significant mineralization associated with the upper oxidized portion of the intermediate sulphidation San Jorge vein.

Hole SG003, within the sulphide zone, intersected 7.43m at 224 g/t AgEq (193 g/t Ag, 0.34% Pb, 0.30% Zn, 0.05 g/t Au) from 86.7m including 0.95m at 754 g/t AgEq (701 g/t Ag, 1.07% Pb, 0.62% Zn, 0.08 g/t Au) from 88.65m and 1.23m at 387 g/t AgEq (356 g/t Ag, 0.34% Pb, 0.39% Zn, 0.12 g/t Au) from 91.74m.

Hole SG004 intersected 6.40m at 108 g/t AgEq (70 g/t Ag, 0.40% Pb, 0.78% Zn, 0.05 g/t Au) from 138.8m including 2.26m at 162m AgEq (103 g/t ag, 0.59% Pb, 1.34% Zn, 0.03 g/t Au) from 138.8m.

Hoel SG005 intersected 3.03m at 92 g/t AgEq (53.5 g/t Ag, 0.13% Pb, 0.21% Zn, 0.32 g/t Au) from 83.60m including 1.07m at 122 g/t AgEq (80 g/t Ag, 0.11% Pb, 0.27% Zn, 0.44 g/t Au) from 84.83.

The high-grade sulphide portion beneath the historic workings at San Jorge and over 1 kilometers of mapped surface vein strike remains to be drill tested. Additional results from holes SG001, SG002, SG003, SG004, SG007 and SG008 are set forth in Table 1 below.

Paquita and Maribel Vein System Results

Three holes for a total of 230.4 meters were drilled across the Maribel and Paquita veins in the north of the property. Drilling tested the near-surface oxide down dip extensions of high-grade silver-gold mineralized intermediate sulphidation epithermal veins.

At Maribel, hole SG010 intersected 4.40m at 134 g/t AgEq (80g/t Ag, 0.16% Pb, 0.34% Zn, 0.44 g/t Au) from 42.7m including 2.66m at 192 g/t AgEq (117 g/t Ag, 0.15% Pb, 0.28% Zn, 0.70 g/t Au) from 43.5m, and intersected a near surface silver grades of 4.1m at 78 g/t AgEq (54 g/t Ag, 0.11% Pb, 0.20% Zn, 0.17 g/t Au) from 12.4m including 1.00m at 126.8 g/t AgEq (99.1 g/t Ag, 0.13% Pb, 0.12% Zn, 0.23 g/t Au) from 13.4m.

Further, at Paquita, SG011 intersected 3.3m at 110 g/t AgEq (65 g/t Ag, 0.15% Pb, 0.43% Zn, 0.31 g/t Au) from 35.4m including 0.48m at 391 g/t AgEq (310 g/t Ag, 0.02% Pb, 0.02% Zn, 0.89% Au) from 36.1m, and hole SG012 intersected 1.0m at 107 g/t AgEq (26 g/t Ag, 0.84% Pb, 1.71% Zn, 0.07 g/t Au) from 42.9m.

Tembladera Vein System Results

Two holes were drilled into the Tembladera Vein system for a of 211.4 meters. One drillhole was drilled to test the near surface down dip extensions of high-grade silver mineralization sampled at surface on the Tembladera 1 vein.

Hole SG015 intersected 0.87m at 131.4 g/t AgEq (72.4 g/t Ag, 0.71% Pb, 1.19% Zn, 0.05 g/t Au) from 115.3m including 0.42m at 224 g/t AgEq (127 g/t Ag, 1.25% Pb, 2.0% Zn, 0.04 g/t Au) from 115.3m.

On additional hole was drilled to intersect the eastern strike extension of the Tembladera vein, the hole missed its target and encountered no significant mineralization. The Company has not yet tested the down dip extensions beneath the historic mine workings which returned up to 10,000 g/t Ag.

Table 1. Assay Results from Drill Program

Additional drilling is required to determine true widths as all hole intercepted veins at an oblique angle. The assays are not capped. Assumptions used in USD for the silver equivalent calculation were metal prices of $28/oz silver, $2500/oz gold, $2900/t zinc, $2100/t lead and 100% recovery.

Quality Assurance / Quality Control

The Company follows industry-recognized standards of Best Practice and Quality Assurance/Quality Control. Samples were submitted to ALS Peru S.A. (ISO 9001:2008) in Lima, Peru in sealed in plastic bags using single use tie-locks, thereby ensuring chain of custody, for fire assay and ICP analysis. To date all batches have passed QAQC within acceptable tolerance limits. All diamond holes were drilled in PQ-NQ diameter. Core recovery across all veins was better than 90%.
