Prospector Reports High-Grade Outcrop

Results up to 156 g/t Au From the Bueno

Target, ML Project, Yukon: Drilling Expected

to Begin by end of June

Vancouver, British Columbia--(Newsfile Corp. - June 10, 2025) -

Prospector Metals Corp.

(TSXV:

PPP) (OTCQB: PMCOF) (FSE: 1ET) ("

Prospector

" or the "

Company

") announces results of 25

surface rock samples collected by Company geologists from the ML Project ("ML") in late May, 2025.

The samples are all from the undrilled Bueno Target. Bueno consists of several mineralized trends

identified as T1, T4, T6 and T8.

Key Point Summary

High-grade surface outcrop samples of 23.6 g/t Au, 51.7 g/t Au, 108 g/t Au, 119 g/t Au and 156 g/t

Au were obtained over the T1 & T6 trends at the Bueno Target. These results significantly extend

the known length of the surface mineralization and are associated with previously undrilled

structural zones.

Additional significant surface results of 5.92 g/t Au and 6.39 g/t Au were obtained from the T4

trend. This trend is likely parallel to the T1 trend separated by approximately 50m. The T4 trends

has also never been drill tested.

Prospector is scheduled to begin its maiden drill program at ML before the end of June. The

program comprises a fully funded diamond drill campaign of 5,000m designed to test high-priority

target areas identified in 2024. At least 6 target areas intend to be drilled including, Bueno, Skarn

Ridge, Rubble, Fishbowl, Java and North Vein targets. A detailed slide deck outlining the specific

target areas and drill strategy can be found at the following link:

Our technical team visited the Bueno target as soon as the snow melted this Spring in order to

ground truth some conceptual ideas constructed over the winter months and the results represent

some of the highest gold assays ever reported from ML,

" stated Rob Carpenter, President and CEO of

Prospector metals Corp. "

We will begin drill testing these targets in the coming weeks."

Descriptions and Results

In late May 2025, a sampling program was conducted to validate geologic controls on the Bueno target

based on analysis of historical results, LiDAR, air photos, and World View – 3 imagery during the winter

months. A total of 25 rock grab and chip samples were collected from outcrop, subcrop, and adjacent

talus and returned results from 0.016 - 156 g/t Au.

Multi-element analysis of the samples is currently in

progress and will be presented in due coarse.

The focus of the work was on four historic blast trenches placed on the target in 1998 over a 300m strike

length and adjacent areas; specifically T1, T4, T6, & T8. Highlights of the historic work included 14.51 g/t

Au over 6m from T1; 1.56 g/t Au over 25m from T4; and grab samples of 210 g/t Au and 387.5 g/t Au

.

The purpose of the 2025 work was to confirm the tenor and location of the historic results and assess the

geological controls on mineralization. Results from the specific areas are discussed in more detail

below.

T1

A total of 9 samples were collected from the T1 area and included samples from outcrop/subcrop of 23.6

g/t Au, 51.7 g/t Au, 119 g/t Au, and 156 g/t Au. The mineralization in the area is hosted within strongly

calc-silicate altered metasediments cut by strong NE and E-W trending fractures with disseminated to

massive arsenopyrite +/- chalcopyrite-pyrrohtite. The strongest mineralization is associated with NE

trending quartz veining, silicification, and localised brecciation that overprints the calc-silicate alteration,

and mineralization is open beyond the limits of the historic trench to the NE and SW.

T4

Four samples were collected from the T4 area and included results of 1.19 g/t Au and 6.39 g/t Au, and

follow up on samples from the 2024 program of 7.42 g/t Au and 34.64 g/t Au

(2)

. Mineralization from the

area appears to be associated with NE trending, strongly altered, fine grained feldspar porphyry dike(s)

with disseminated arsenopyrite-chalcopyrite mineralization.

T6

Six samples were collected from outcrop/subcrop on the ridgeline above the T6 trench and included

results of 1.8 g/t Au and 108 g/t Au. The mineralization is similar to T1 and consists of disseminated to

massive arsenopyrite-chalcopyrite within calc-silicate altered metasediments with strong NE oriented

fracturing, localised brecciation, and quartz veining/silicification. The northern portion of T6 could not be

assessed due to snow cover.

T8

Five samples were collected from the T8 area and included results of 5.92 g/t Au. The mineralization

occurs within strongly fractured calc-silicate altered metasediments with disseminated to massive

arsenopyrite +/- chalcopyrite on the margin of a NNE trending, steeply dipping, megacrystic feldspar

porphyry dike.

Overall, the program confirmed the historic sampling results and indicate that gold mineralization in the

Bueno area is controlled by a series of NNE trending, steeply dipping structural trends and associated

feldspar porphyry dikes with secondary controls including lithologic contacts and structural intersections.

Gold mineralization appears to be late with the highest-grade values associated with quartz veining,

silicification, and localised brecciation that overprints early calc-silicate alteration. It should be noted, one

historic drill hole (SK05-01) is located in the Bueno area and returned only anomalous results. However,

the hole was drilled to the north and the current interpretation indicates it was drilled subparallel and

outside of the mineralized structural trends.

Bueno is a high priority drill target for the upcoming maiden ML drill program scheduled to begin before

the end of June. The program comprises a fully funded diamond drill campaign of 5,000m designed to

test high-priority target areas identified in 2024. At least 6 target areas intend to be drilled including,

Bueno, Skarn Ridge, Rubble, Fishbowl, Java and North Vein targets. A detailed slide deck outlining the

specific target areas and drill strategy can be found at the following link:

Assay Methodology & QA/QC

The analytical work on the ML Project was performed by AGAT Labs, an internationally recognized

analytical services provider, located in Calgary, Alberta. All rock samples were prepared using

procedure 200-075 (Dry, crush to 70% passing 2mm, riffle split off 250g, pulverize split to better than

85% passing 75 microns) and analyzed by method 202-051 (30g fire assay with AAS finish) and 201-

074 (Multi-element analysis with aqua regia digest and ICP-OES/MS finish). Samples containing >10g/t

Au were reanalysed using a 50g Fire Assay with a Gravimetric finish. Samples containing >100 ppm Ag

and/or >1% Cu, Pb, & Zn were reanalyzed using a 4-acid digest and ore grade ICP-OES analysis.

The reported work was completed using industry standard procedures, including a quality

assurance/quality control ("QA/QC") program consisting of the insertion of certified standard, blanks and

duplicates into the sample stream. The Qualified Person has reviewed the data and detected no QA/QC

issues.
