PRINCE SILVER COMMENCES FULLY FUNDED DRILL PROGRAM AT THE PRINCE SILVER PROJECT IN NEVADA

Prince Silver Corp. (formerly Hawthorn Resources Corp.) has commenced a fully financed, 6,500-metre exploration drill program at its flagship Prince silver project, a past-producing silver-zinc-gold-lead property. The program is designed to expand known high-grade zones, validate historical drilling and define the broader mineralized system across the property.

Key highlights:

• Thirty-one reverse circulation holes totalling approximately 6,500 metres are planned in this first-phase drilling,
• One hundred twenty-nine historical holes (16,607 metres) confirm widespread mineralization and high-grade zones.
• The drill program is fully financed following the closing of two recent financings, totalling over $5.25-million.

Ralph Shearing, president and director, said: "We're excited to launch this fully funded drill program at the Prince silver project, which we believe holds significant untapped potential. Our work will focus on expanding known high-grade zones, testing new areas and validating historical drilling. With approximately 6,500 metres of drilling planned, and mineralization open in all directions, this program marks a key step in defining the broader mineralized system and positioning Prince Silver as a standout silver explorer in Nevada."

2025 drill program

The program will consist of approximately 6,500 metres of RC drilling across 31 holes. It is designed to validate historical results, increase confidence in historic unpublished resources estimates, and complete infill and stepout drilling within and surrounding the historic resource area. The goal is to advance the project toward a maiden National Instrument 43-101 resource estimate by testing potential extensions to know mineralization along strike and to depth. The drill program is being conducted by O'Keefe Drilling Company, headquartered in Butte, Mont.

The Prince silver project hosts a significant polymetallic carbonate replacement deposit and a sediment-hosted gold system, with mineralization that is open in all directions and amenable to open-pit mining and deeper underground mining. The project benefits from shallow, high-grade zones and holds potential for valuable manganese byproducts.

Initial assay results from the program will be published as they become available from the laboratories, with continuing results as the drill program progresses into winter.

Prince silver project historic exploration

To evaluate the mineral potential of the Prince project, an exploration target was outlined in a 2024 independent report prepared following Joint Ore Reserves Committee 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 exploration target was based on 129 historic drill holes drilled through mineralized carbonate replacement beds that host a Pioche shale up to 500 metres deep. Mineralized polymetallic intersections based on historical block modelling suggests the immediate exploration target is between 25 million to 43 million tonnes with grades ranging as 1.44 to 1.57 per cent zinc, 0.78 to 0.87 per cent lead, 0.003 to 0.005 per cent copper, 0.28 to 0.40 gram per tonne gold, 37 to 40 g/t silver and 3.62 to 4.30 per cent manganese. The mineralization is open in all directions.

Readers are cautioned that the exploration target is not an inferred, indicated or measured mineral resource compliant with National Instrument 43-101. The exploration target has been determined based upon 129 historic drill holes totalling 16,606 metres, historic production records including mine level plans, and 3-D modelling of mineralization and geology. The potential quantity and grade of the exploration target are 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.

Previous drilling and results

Historical exploration includes 129 drill holes totalling 16,607 metres. Results confirm widespread mineralization and multiple high-grade zones.

Notable 2014 intercepts:

• 40.8 metres of 0.63 g/t Au, 65 g/t Ag, 1.64 per cent Zn and 3.51 per cent Pb (from 26 m, UDH-55);
• 24.4 m of 0.47 g/t Au, 80 g/t Ag, 1.64 per cent Zn and 3.52 per cent Pb (from 87 m, PRC-11);
• 2.4 m of 11.1 g/t Au, 377 g/t Ag, 26.1 per cent Zn and 4.3 per cent Pb (from 14 m, UDH-53).

Importantly, earlier programs only sporadically assayed the Pioche shale unit; however, where assayed, the Pioche shale returned a number of highly prospective historic results such as:

• 61 m of 2.1 g/t Au and 38 g/t Ag (from 69 m, CDH-36);
• 41 m of 0.7 g/t Au, 68 g/t Ag, 3.3 per cent Zn and 0.61 per cent Pb (from 26 m, UDH-55);
• 71 m of 1.4 g/t Au and 51 g/t Ag (from 192 m, PRC-10).
