Prince Reports 27.43 Metres Grading 93.7 g/t Silver, 12.0% Mn, 2.29% Pb and 2.48% Zn at Its Prince Silver Project in Nevada

May 19, 2026

Vancouver, British Columbia--(Newsfile Corp. - May 19, 2026) - Prince Silver Corp. (CSE: PRNC) (OTCQX: PRNCF) (FSE: T130) ("Prince Silver" or the "Company") is pleased to announce additional assay results from its ongoing 9,000-metre reverse circulation ("RC") drilling program at the Company's Prince Silver Project ("Prince" or the "Prince Project"), located in the historic Pioche Mining District, Lincoln County, Nevada.

Drilling results from the Prince Project continue to deliver broad zones of high-grade silver mineralization with strong lead, zinc and emerging gold values across multiple stacked horizons, reinforcing the Project's growing scale and polymetallic potential.

The latest results, summarized in Table 1 and shown spatially in Figure 1, further validate historical drilling while expanding known mineralized zones ahead of a maiden NI 43-101 resource estimate. These results also continue to support the Company's objective of systematically testing the historical Exploration Target described below. Hole PRC-46 returned one of the strongest gold intercepts of the current campaign. Previous drilling also reported gold-bearing mineralization at Prince in multiple holes across significant widths, as disclosed in the Company's news releases dated January 13, 2026 and March 19, 2026.

With a third RC drill rig now mobilized, Prince Silver is accelerating drilling activity and positioning for a steady stream of catalysts and discovery-driven news flow in the weeks and months ahead.

Drilling Highlights include:

PRC-45:27.43 metres grading 93.7 g/t Ag, 12.0% Mn, 2.29% Pb, 2.48% Zn and 0.12 g/tAu from 94.49 metres depth in the Lyndon Limestone, including:
- 12.19 metres grading 130.1 g/t Ag, 11.0% Mn, 3.06% Pb, 3.30% Zn and 0.14 g/t Au
PRC-45:3.05 metres grading 124.5 g/t Ag, 7.10% Mn, 3.26% Pb, 5.78% Zn and 0.24 g/t Au from 13.72 metres depth in the Highland Peak Limestone
PRC-46: 10.67 metres grading 1.36 g/t Au, 55.1 g/t Ag, 0.87% Mn, 0.71% Pb and 0.83% Zn from 188.98 metres depth in the Combined Metals Bed

Derek Iwanaka, CEO and Director of Prince Silver, commented:

"These latest results continue to demonstrate the scale, continuity and expanding polymetallic potential of the Prince Project. PRC-45 delivered broad zones of silver-rich polymetallic mineralization, while PRC-46 returned one of the strongest gold intercepts of the program, reinforcing the growing importance of gold within the system. With a third RC rig now turning and additional assays pending, we are accelerating toward a maiden NI 43-101 resource estimate and believe Prince is emerging as one of the most compelling silver-gold CRD discoveries in Nevada."

Discussion of Results

The latest results confirm mineralization across several stratigraphic horizons, including the Highland Peak Limestone, Lyndon Limestone, Pioche Shale units, Combined Metals Bed and Prospect Mountain Quartzite.

Hole PRC-45 demonstrates both near-surface and deeper mineralization within the western-central portion of the current drill area. The broad 27.43 metre interval from 94.49 metres depth confirms substantial silver-manganese-lead-zinc mineralization within the Lyndon Limestone, including a higher-grade core of 12.19 metres grading 130.1 g/t Ag, 11.0% Mn, 3.06% Pb and 3.30% Zn. The hole also returned strong near-surface mineralization from 13.72 metres depth in the Highland Peak Limestone.

Hole PRC-46 is particularly important for demonstrating the gold potential within the broader Prince system. The interval of 10.67 metres grading 1.36 g/t Au and 55.1 g/t Ag in the Combined Metals Bed, together with additional gold-bearing intervals deeper in the Pioche "D" Shale and Prospect Mountain Quartzite, suggests gold may contribute more meaningfully to future resource modelling than previously anticipated.

Assays from additional holes remain pending and will be released as they are received, compiled and reviewed.

Ongoing Drill Program

The current RC drill program is focused on validating historical drilling, testing continuity between known zones, and expanding mineralization along strike and down-dip. The program is also improving the Company's understanding of gold distribution across the system, which may become an important component of the overall polymetallic resource potential.

A third RC drill rig has been mobilized to site to improve drilling productivity. Management expects the additional rig to help accelerate completion of the remaining program.

Historical Exploration Target

Historical drilling at the Prince Project identiﬁed an exploration target (the "Exploration Target") as outlined in an independent historic report prepared following JORC guidelines (JORC standards for the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves) by OmniGeoX Exploration Consultants of Perth, Australia, based on historical surface and underground drilling. The report is titled "Prince Project Exploration Target", dated April 24, 2024, authored by Dr. Lachlan Rutherford and Michael Martin (OmniGeoX Exploration Consultants, 2024, Prince Project Exploration Target, Independent Report prepared for Prince Silver Corp.).

The Exploration Target was based on 129 historic drill holes drilled through mineralized carbonate replacement beds and host Pioche Shale up to 300 metres in depth. Mineralized polymetallic intersections based on historical block modelling suggest the immediate Exploration Target is between 25-43 Mt with grades ranging from 1.44-1.57% Zn, 0.78-0.87% Pb, 0.28-0.40 g/t Au, 37-40 g/t Ag and 3.62-4.30% Mn.

More comprehensive details on the Exploration Target and historic production are also available in the Company's press release dated February 27, 2025, available on the Company's website and at SEDAR+.

* Readers are cautioned that the Exploration Target is not an "inferred", "indicated" or "measured" mineral resource compliant with National Instrument 43-101 ("NI 43-101"). The Exploration Target has been determined based upon 129 historic drill holes totaling 16,606 metres, historic production records including mine level plans and 3D modelling of mineralization and geology. The potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to deﬁne a mineral resource, and it is uncertain if further exploration will result in the Exploration Target being delineated as a mineral resource.

Quality Assurance / Quality Control

The Company is following a robust Quality Assurance / Quality Control (QA/QC) program designed to meet or exceed CIM and AusIMM standards. Duplicate samples are extensively used to provide verification both at the primary analytical laboratory and at a second independent laboratory as the program progresses. In addition, a certified field standard is inserted for each drill hole set, and sample blanks are randomly included, with no more than one per hole.

All samples are shipped to the laboratory under secure, standard chain-of-custody procedures. Samples are analyzed using 43-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.
