Andean Precious Metals Reports 2024 Exploration Results and Outlines 2025 Program at Golden Queen

Toronto, Ontario--(Newsfile Corp. - May 1, 2025) - Andean Precious Metals Corp. (TSX: APM) (OTCQX: ANPMF) ("Andean" or the "Company") is pleased to provide an update on year-end 2024 exploration activities and exploration plans for 2025 for its Golden Queen mine located in Kern County, California. The Company's focus remains on extending mine life by expanding the current mining zones on the south side of the current pit design.

At the beginning of 2024, the Company's exploration approach consisted of two distinct phases:

• Phase 1 consisted of 29 shallow infill reverse circulation ("RC") drill holes that were completed in July 2024 totaling 4,617 metres of drilling;

  • 12 RC holes for a total of 1,360 metres in the Silver Queen Southeast Trend (Main Pit 2 and Main Pit 3) confirming the geological model and validating the approach for phase 2 and;

  • 17 RC holes for a total of 3,257 metres in Alphason with the objective of defining the geological structure and testing the continuity defined with the prior exploration campaign results of 2022.

• Phase 2 had three main objectives with 4,330 metres of core drilling planned:

  • Increase mineral resources and mineral reserves in the Silver Queen South-East trend and Alphason;

  • Test the geological continuity at Alphason to improve our understanding of the geologic controls of mineralization and;

  • Test, for the first time, the new Hilltop area located south of the Silver Queen Southeast Extension that has the potential to connect to the Main Pit 2.

The Company released the initial results of the 2024 exploration campaign in a press release dated January, 16, 2025.

The Company is now pleased to share additional highlights of the 2024 exploration campaign:

• Phase 1 shallow RC drilling confirmed the geological interpretation and accuracy of the block model;

• Phase 2 completed with 23 core holes totaling 4,123 metres compared to the initial plan of 4,330 metres;

• The 2024 exploration program met expectations with all 23 core holes intersecting gold and silver mineralization;

• 12 core holes in Silver Queen Southeast have extended the mineralization longitudinally by 100 metres on strike in the southeast trend direction, including hole SQ24-06 with 1.67 grams per tonne (g/t) of gold and 8 g/t of silver over 5.49 drill metres;

• 7 core holes in Alphason including hole AL24-02 with 0.88 g/t of gold and 10 g/t of silver over 92.96 drill metres and;

• 4 core holes in the new Hilltop target including hole SQ24-12 which intersected mineralization grading 1.67 g/t of gold and 20 g/t of silver over 5.89 drill metres starting at 18.14 metres downhole.

Mr. Alberto Morales, Executive Chairman and CEO, stated, "I am pleased with the 2024 exploration campaign confirming our initial view on the exploration potential at Golden Queen. The exploration team is delivering on the objective of increasing Golden Queen's mine life by expanding methodically the current mining areas in the south-east trend. The close to surface Hilltop area provides mining flexibility by adding one more mining area with anticipated first ore in the third quarter of 2025. I am particularly pleased with these first results at the Alphason confirming the geo-structural model and the exploration strategy."

Golden Queen's 2025 exploration program is focused on extending the mine life through continued resource growth. The Company has allocated an initial budget of $2.8 million, which includes approximately 4,267 metres of core drilling targeting the Silver Queen Southeast Extension, including the Hilltop area, as well as ongoing testing of the Alphason target.

Andean expects to release exploration results in the second half of 2025 and plans to update the Golden Queen Technical Report as of year end, with the revised report anticipated in the first half of 2026.

Table Notes:

1. "na" means "not applicable".
2. All drill and assay data originally reported in imperial units converted to metric.
3. 4,123 metres of 22 HQ-sized core (63.5 mm) and 207 metres in 1 PQ-sized core (85 mm) sampled with variable sample lengths. Mineralization widths are down-hole, true widths are not yet known.
4. A total of 3,055 core samples plus 433 samples for QAQC purposes were submitted for analyses performed by Paragon Geochemical; an ISO 17025 accredited analytical services provider with sample preparation and analytical facilities in Sparks, NV, USA.
5. Analytical methods used for gold were Au-FA 30 for gold and 48MA-MS for silver.
6. A 0.34 gold g/t cutoff grade used in compositing. No more than 2 consecutive values less than the cutoff were used. Grades were not capped.
7. An additional 12% blanks, standards and duplicates were submitted for QAQC purposes. This consisted of 163 blanks, 151 certified reference materials (CRM) and 119 duplicates. Twenty analyses (0.65%) from QAQC standards were slightly outside of the acceptable limits, as defined in Company protocols, and are being checked by the Golden Queen geologic staff.
