Prince Silver Corp. (CSE: PRNC) (OTCQX: PRNCF) (FSE: T130) is pleased to announce five additional drill hole assay results from its ongoing 9,000-metre reverse circulation drilling program at the Company’s Prince Silver Project, located in the historic Pioche Mining District, Lincoln County, Nevada.

Results from five additional drill holes continue to demonstrate the scale and continuity of the Prince mineralizing system, confirming extensive silver-manganese-lead-zinc mineralization within the upper oxide horizon while further highlighting the growing significance of gold-rich sulphide mineralization at depth.

A key highlight was returned from hole PRC-44, which intersected 15.24 metres grading 2.41 g/t gold and 68.5 g/t silver from 259.08 metres, representing one of the strongest gold-bearing intervals encountered by the Company to date and reinforcing the emerging gold potential of the Project.

The Company has now received assay results from 25 of the initial 30 drill holes, with results continuing to validate management’s geological model and strengthen confidence in the potential for a large-scale, multi-metal mineralized system. In response to the success of the program, Prince Silver plans to expand the current campaign by a minimum of 10 additional drill holes.

• PRC-50: High-grade Ag-Mn mineralization, including
  • 3.05 m grading 131.5 g/t Ag, 8.91% Mn, 0.75% Pb and 1.35% Zn from 185.93 m

Reported intervals are downhole lengths. Apparent widths are considered close to true widths where holes were drilled approximately perpendicular to gently dipping mineralized beds; true widths have not been definitively established

“Gold continues to emerge as a very meaningful component of the Prince mineralizing system,” said Derek Iwanaka, Chief Executive Officer of Prince Silver. “The PRC-44 intersection is one of the strongest gold results returned to date and provides further evidence that Prince hosts a distinct gold-rich sulphide horizon beneath, and potentially alongside, the broad silver-manganese-rich oxide mineralization historically exploited at the mine.”

“Just as importantly, these results continue to build our confidence that Prince hosts a large and expanding mineralized system with the scale required to support a meaningful mineral resource. We are seeing broad, consistent silver-manganese-lead-zinc mineralization across much of the project, together with higher-value gold-silver mineralization deeper in the system. This combination of width, grade and metal diversity is particularly encouraging as we continue to define the overall footprint of the system.”

“The growing gold contribution, together with zinc, lead and manganese, has the potential to materially improve the economic profile of the project beyond silver alone. Our objective is not only to define tonnes and grade, but to demonstrate a robust multi-metal system that could offer several potential value drivers as we advance toward a maiden mineral resource estimate.”

“With assays now in hand from 25 of our initial 30 holes, we believe the results justify extending the current drill program by at least ten more holes advancing Prince toward our maiden NI 43-101 mineral resource estimate, targeted for year-end 2026.”

These latest results build on previously reported drilling at Prince. As disclosed in the Company’s January 13, 2026 news release, earlier drilling returned 3.05 metres grading 355 g/t Ag, 4.78 g/t Au, 2.69% Pb and 4.72% Zn in PRC-27, together with 3.05 metres grading 1,331 g/t Ag, 14.17% Mn, 2.19% Pb and 4.45% Zn in PRC-28.

As reported in the Company’s May 19, 2026 news release, PRC-41 returned 27.43 metres grading 93.7 g/t Ag, 12.0% Mn, 2.29% Pb and 2.48% Zn. Together with the latest PRC-44, PRC-47, PRC-48 and PRC-50 results, these intersections support the Company’s interpretation of a broad, multi-horizon mineralizing system containing both extensive silver-manganese-rich oxide mineralization and an increasingly compelling gold-silver-rich sulphide component.

The latest holes are distributed across a broad portion of the 2026 drill footprint, extending from the northern area around PRC-48 and PRC-50, through the central Prince Mine area represented by PRC-44, and into the southeastern portion of the project where PRC-47 and PRC-49 were drilled. This broad distribution of mineralized intersections supports the Company’s interpretation that Prince hosts a large, multi-horizon mineralizing system. Additional drilling is required to establish the continuity, geometry and full extent of mineralization.

PRC-49 Follow-Up Hole Planned

Hole PRC-49 did not reach its intended target depth and therefore did not adequately test the projected continuation of mineralization in that area. The Company does not consider PRC-49 to be a definitive test of the target.

Prince Silver plans to drill a replacement hole in close proximity to PRC-49 to better evaluate the favourable stratigraphic and structural setting and test for the continuation of gold-silver and polymetallic mineralization encountered in nearby drill holes.

Ongoing Exploration

The current drill program is increasingly demonstrating the potential for Prince to host a large, multi-horizon mineralized system. Broad near-surface silver-manganese-lead-zinc oxide mineralization is being defined above gold-silver-rich sulphide mineralization, providing multiple potential sources of value within the same overall system.

The planned drill extension is designed to expand the known mineralized footprint, test priority gold-silver and polymetallic step-out targets, and provide additional drilling density for the Company’s geological model and planned maiden NI 43-101 mineral resource estimate.

While no mineral resource has yet been established, the Company believes the growing consistency of mineralization, combined with the contribution from gold and other base metals, supports continued aggressive exploration of the project’s resource and economic potential.

Quality Assurance / Quality Control

The Company is following a robust Quality Assurance / Quality Control program designed to meet or exceed CIM and AusIMM standards. The program consists of randomly inserting two certified standards, one blank, one pulp duplicate and one reject duplicate into each sample batch sent to the primary laboratory. In addition, returned pulps are selected to be sent to a second independent laboratory for check assaying.

All samples are shipped to the laboratory under secure, standard chain-of-custody procedures. Samples are analyzed using 44-element MS-ICP with aqua regia digestion. Samples exceeding limits for Mn, Zn, or Pb are further tested using wet chemical assays. Most samples are also fire assayed for gold and silver using a one-assay-ton gravimetric method, and an average of four samples per hole will have specific gravity measurements conducted at the laboratory.

The principal analytical laboratory for the program is Skyline Assayers & Laboratories Inc., located in Tucson, Arizona, an ISO-accredited facility.
