Two of the Widest Silver Intersections to Date at Shallow Depths: 47 Metres at 68.2 g/t Silver (119.1 g/t Silver Equivalent) and 37 Metres at 86.3 g/t Silver (146.3 g/t Silver Equivalent)

Historical drilling is being assessed for possible inclusion in a maiden mineral resource estimate targeted for early 2027.

Rhea-AI Summary

Prince Silver (PRNCF) reported nine drill-hole results from its Nevada project, including two broad silver intersections near historical workings. PRC-59 intersected 47.24 metres at 68.17 g/t silver from 62.48 metres downhole; PRC-60 returned 36.58 metres at 86.30 g/t silver from 64.01 metres. Both Lyndon Limestone intervals exceed the previously reported 27.43-metre intersection in PRC-45. PRC-54 also returned 3.05 metres at 619.60 g/t silver, including 1.52 metres at 1,215.00 g/t.

As of September 27, 2026, drilling totaled 41 holes and 11,251 metres. Prince Silver targets a maiden mineral resource estimate for early 2027, while historical data validation continues; no resource has yet been established. Assays for PRC-61 through PRC-65 are pending. PRC-56 was abandoned and its replacement completed; technical difficulties stopped PRC-59 before its deeper target.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Vancouver, British Columbia--(Newsfile Corp. - October 6, 2026) - Prince Silver Corp. (CSE: PRNC) (OTCQX: PRNCF) (FSE: T130) ("Prince Silver" or the "Company") is pleased to report results from nine reverse circulation ("RC") drill holes at its Prince Silver Project in Nevada, highlighted by two near-surface intersections hosting the broadest polymetallic mineralization delivered by the Company's ongoing drill program to date.

Drill holes PRC-59 and PRC-60 intersected 47.24 metres at 68.17 g/t Ag (119.13 g/t AgEq) and 36.58 metres at 86.30 g/t Ag (146.27 g/t AgEq), respectively, within the Lyndon Limestone near historical mine workings. The results underscore the scale and continuity of mineralization at the Prince Silver Project and further demonstrate the potential for significant mineralization beyond the historical workings.

The latest drilling continues to intersect substantial silver-polymetallic mineralization across multiple prospective horizons, including the Lyndon Limestone, Pioche Shales and Combined Metals Bed. These results add important current drill data to the Company's geological model as Prince Silver advances toward a maiden mineral resource estimate.

New Drilling Highlights (Silver Equivalent "AgEq" grades do not include Manganese)

PRC-59:

• 47.24 metres at 68.17 g/t Ag (119.13 g/t AgEq), 9.57% Mn, 2.40% Zn, 1.95% Pb and 0.26 g/t Au from 62.48 m downhole.
• 6.10 metres at 142.50 g/t Ag (208.28 g/t AgEq), 10.95% Mn, 4.05% Zn, 3.01% Pb and 0.22 g/t Au in the shallower Chisholm Shale.

PRC-60:

• 36.58 metres at 86.30 g/t Ag (146.27 g/t AgEq), 9.46% Mn, 3.08% Zn, 2.20% Pb and 0.28 g/t Au from 64.01 m downhole.
• 16.76 metres at 85.98 g/t Ag (115.69 g/t AgEq), 5.61% Mn, 1.50% Zn, 1.66% Pb and 0.21 g/t Au in the deeper Combined Metals Bed, including 1.52 metres at 347.00 g/t Ag (365.87 g/t AgEq).

PRC-54:

• 3.05 metres at 619.60 g/t Ag (665.07 g/t AgEq), 2.105 g/t Au, 3.66% Zn and 0.15% Pb in the Pioche "D" Shale, including 1.52 metres at 1,215.00 g/t Ag (1,297.58 g/t AgEq), 4.16 g/t Au, 6.67% Zn and 0.13% Pb.

PRC-55:

• 4.57 metres at 106.10 g/t Ag (238.77 g/t AgEq), 13.0% Mn, 2.98% Zn, 1.29% Pb and 1.816 g/t Au in the Combined Metals Bed.

PRC-58:

• 4.57 metres at 55.57 g/t Ag (119.36 g/t AgEq), 8.74% Mn, 3.92% Zn, 2.09% Pb and 0.05 g/t Au in Pioche "B" Shale, plus 3.05 metres at 51.47 g/t Ag (231.48 g/t AgEq), 2.16 g/t Au, 4.48% Zn and 0.90% Pb in Pioche "D" Shale.

Illustrative AgEq basis excluding Mn: AgEq (g/t) = 0.80 × [Ag + 70 × Au + 17.14285 × Zn% + 10.97142 × Pb%]. Prices: US$50/oz Ag, US$3,500/oz Au, US$1.25/lb Zn and US$0.80/lb Pb. The 80% recovery is assumed for each included metal; AgEq is divided by the silver price without a further recovery adjustment. AgEq values are rounded to two decimal places. Mn is excluded. Recoveries have not been established for every interval; payability and costs are excluded.

Element symbols: Ag = silver; Au = gold; Zn = zinc; Pb = lead; Mn = manganese.

Derek Iwanaka, Chief Executive Officer, commented: "PRC-59 and PRC-60 have delivered two of our most substantial broad polymetallic intersections to date. It is especially exciting to find shallow intervals of this scale near historical workings: they show that meaningful mineralization remains around the old mine. We are also repeatedly encountering mineralization in the Lyndon Limestone, Pioche Shale and Combined Metals Bed. PRC-60 offers a close comparison with historical underground drilling, while the pending twin-hole assays will help test the historical database. Together, these modern results are sharpening our geological model and building confidence in the technical foundation for a maiden mineral resource estimate."

As of September 27, 2026, the Company has completed 41 holes totaling 11,251 metres of drilling in its ongoing RC program at Prince.

Drilling Interpretation

The Lyndon Limestone intervals in PRC-59 and PRC-60 are wider than the Company's previously reported 27.43 metres grading 93.7 g/t Ag in PRC-45. These broad intersections show meaningful mineralization remains in the tested ground near historical workings. Their assays and geological observations add control to the interpretation of this horizon and allow comparison with historical mine plans.

PRC-60 also intersected the Combined Metals Bed near two Prince 835-level historical underground holes, estimated to be within 26 and 38 metres from the PRC-60 intersection. This intersection allows the Company to compare zone continuity and assays with the underground records and assess the historical holes for possible use in the maiden resource estimate.

PRC-51 through PRC-55, PRC-57 and PRC-58 add data from the Combined Metals Bed and Pioche Shale units. The repeated zone picks align with the historical interpretation of stacked replacement horizons in a faulted corridor. The new assays and geological observations help correlate those horizons with historical drill hole logs and mine plans and confirm how local faulting affects their relative positions.

The Company and its independent resource consultants are incorporating these observations and data into the geological model as historical information is validated. These correlations will help confirm mineralized domains for a maiden NI 43-101 mineral resource estimate targeted for early 2027. No mineral resource has yet been established for Prince.

Drilling and Resource Work

PRC-56 did not reach its target depth; however, PRC-65 was drilled as a replacement hole and was recently completed. Assays for holes PRC-61 through PRC-65 are currently pending.

PRC-59 was terminated at 158.5 metres after technical difficulties, before reaching the deeper Combined Metals Bed target. It nonetheless intersected 47.24 metres grading 68.2 g/t Ag, 9.57% Mn, 2.40% Zn, 1.95% Pb and 0.26 g/t Au in the Lyndon Limestone, one of the broadest mineralized intervals in the current program. These results provide assay and geological data near historical mine workings.

PRC-61 and PRC-62 were drilled as twins of 2012 historical holes PRC-10 and PRC-17, respectively. Once assays are reviewed, comparisons of geology, mineralized interval positions and grades will help assess the historical drilling database for possible use in the maiden resource estimate.

Quality Assurance and Quality Control

The RC assays in this release are supported by finalized ALS Geochemistry certificates. The Company inserts two certified reference standards, one blank, one pulp duplicate and one reject duplicate into a typical batch of 45 rock samples. Control-sample results are plotted and monitored, and returned pulps are selected for check assaying at a second independent laboratory.

Samples are shipped under chain-of-custody procedures to ALS in Reno, Nevada, for preparation and then to ALS in Vancouver, British Columbia, for analysis. Au is determined by Au-ICP22 fire assay, with additional follow-up assays where required; Ag and other elements are analyzed using the AuME-TL44 aqua regia method. Overlimit Ag, Mn, Zn and Pb results are determined using follow-up methods identified in the ALS certificates.

Forward-Looking Information

This news release contains forward-looking statements and forward-looking information within the meaning of applicable securities laws (collectively, "forward-looking statements"). Such statements are often identified by words including "expects," "plans," "estimates," "potential," "may," "will," "could" and "should," and similar expressions.

Forward-looking statements in this news release include interpretations of current and historical drilling, including the continuity and extent of stacked mineralized horizons and their relationship to historical workings; pending assays for PRC-61 through PRC-65 and the significance of twin-hole comparisons; validation and possible use of historical data in resource modelling; further drilling, metallurgical studies and geological modelling; and the timing, completion and outcome of a maiden NI 43-101 mineral resource estimate targeted for early 2027.

These statements assume, among other things, that current assays and geological data are reliable; relevant historical drilling and mine plans can be validated; geological correlations and mineralization between intercepts can be interpreted accurately; laboratory services, consultants, personnel, equipment, drill rigs and financing remain available on reasonable terms; and required permits and approvals are obtained.

Actual results could differ materially because pending assays or twin-hole comparisons may not support current interpretations; historical data may not be validated or used in a mineral resource estimate; mineralization between holes may differ in continuity, geometry, width or grade; assays, drilling, technical work or modelling may be delayed; metallurgy or resource-estimation work may not support a mineral resource; financing, personnel, contractors or permits may be unavailable; and market conditions or commodity prices may change. Other risks are described in the Company's continuous disclosure filings.

Readers are cautioned not to place undue reliance on forward-looking statements. These statements are made as of the date of this news release. The Company undertakes no obligation to update or revise them, except as required by applicable law.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What were Prince Silver's broadest new silver drill intersections?

PRC-59 returned 47.24 metres at 68.17 g/t silver, and PRC-60 returned 36.58 metres at 86.30 g/t silver. The intervals begin at 62.48 and 64.01 metres downhole, respectively, in the Lyndon Limestone near historical workings.

How does Prince Silver calculate silver-equivalent drill grades?

Prince Silver's illustrative silver-equivalent calculation includes silver, gold, zinc and lead, assumes 80% recovery for each included metal, and excludes manganese. It uses prices of US$50/oz silver, US$3,500/oz gold, US$1.25/lb zinc and US$0.80/lb lead. Recoveries have not been established for every interval; payability and costs are excluded.

How is Prince Silver testing historical drilling for its maiden resource estimate?

PRC-61 and PRC-62 were drilled as twins of the 2012 historical holes PRC-10 and PRC-17, respectively. After assay review, comparisons of geology, mineralized interval positions and grades will help assess whether historical drilling can be used in the maiden resource estimate.
