Surface Mapping and Sampling Extends Skarn Ridge Corridor an Additional 750m Along Trend: High-Grade Grab Samples Yield 57.8 g/t Au and 109 g/t Au

Skarn Ridge is Located 4 kilometres Southwest of the Recently Discovered TESS Zone. The Gap Between These Two Zones Remains Largely Unexplored

Prospector Metals Corp. (TSX-V: PPP) (OTCQB: PMCOF) (FSE: 1ET) announced final assay results for 12 drill holes from the Skarn Ridge – Bueno Trend (ML25-12 to 23). The Skarn Ridge – Bueno Corridor can now be traced in drilling for at least 1.4 kilometres and new mapping and prospecting results suggest it extends at least 2.0 kilometres. Skarn Ridge is located 4 kilometres to the southwest of the recently discovered TESS Zone. This 4km gap has yielded some high grade gold surface samples in limited work to date (Figure 1) but remains largely unexplored.

Drill results have now been released for 24 of 39 holes drilled property-wide in 2025. Results remaining are from holes drilled at Skarn Ridge (8 holes), Bueno (4 holes), TESS – North Vein area (1 hole), Fishbowl (1 hole) and Lorrie (1 hole).

Rob Carpenter, Ph.D., PGeo., President, CEO and Co-Chairman of Prospector, stated: “Skarn Ridge represents a wide structural corridor hosting multiple, parallel trending gold zones which are dipping near vertical. These zones are open along trend and at depth. Skarn Ridge is a distinct zone from our newly discovered TESS Zone, separated by a 4-kilometre gap that will be further evaluated in our next phase of exploration. Our maiden drill program in 2025 has successfully identified numerous high-grade gold trends across the claim block suggesting the presence of a district-scale mineralizing system.”

Key Point Summary

• The Skarn Ridge – Bueno Corridor can now be traced in drilling for at least 1.5 kilometres and new mapping and prospecting results suggest it extends at least 2.0 kilometres. Drill results include 2.97 g/t Au over 25m from 137m downhole (ML25-014), 61.45 g/t Au over 1.9m from 21.9m downhole plus 4.64 g/t Au over 10m from 51m downhole (ML25-022), and 141 g/t Au over 0.5m from 63.75m downhole (ML25-023).

• Significant intervals of Copper (Cu) were also intersected at Skarn Ridge including 0.72% Cu over 41.15m from 83m downhole (ML25-012), 0.61% Cu over 20m from 108m downhole (ML25-013), and 0.54% Cu over 14.45m from 166m downhole (ML25-019).

• New prospecting results along the projected extension of Skarn Ridge have yielded up to 57.8 g/t Au and 109 g/t Au from grab samples. Additional surface prospecting results from the TESS area are pending.

• The next phase of exploration will include follow up drilling on both the TESS-Java and Skarn Ridge-Bueno discovery areas, as well as further exploration of the prospective 4km gap between these zones.

Skarn Ridge – Bueno Trend Interpretation 

The assays received to date and visual observations from pending holes confirm that gold mineralization from Skarn Ridge to Bueno is hosted within a series of north-northeast trending, steeply dipping, structural zones and associated splays. Individual mineralized trends range from 1-2m wide up to 44m wide and can be traced in multiple drill holes (i.e. ML-10-13 and 22-23). The corridor has now been traced over 1.5km along strike and have over 600m of vertical continuity. The 2025 drilling at Skarn Ridge – Bueno successfully confirmed key structural interpretations for the ML project resulting in a new exploration model that can be applied project-wide.

Within the structural corridors, gold mineralization is noted in every rock type on the Skarn Ridge-Bueno Trend and is best developed within strongly fractured/brecciated calc-silicate altered and/or iron rich units, and along lithologic contacts. The gold mineralization is, locally, coincident with significant copper mineralization, however, the gold and copper mineralizing events appear to be independent of each other. Gold is focused within structural corridors and is strongly associated with bismuth and tellurium mineralization, whereas copper is more broadly distributed and only occurs within strongly calc-silicate altered units.

Skarn Ridge

A total of 2,976.84m over 18 drill holes were completed on the Skarn Ridge target. To date, results have been received for ten holes; including previously announced results on ML25-10 & -011⁽¹⁾. The holes were designed to test previously unrecognized north-northeast trending structural controls associated with historically reported gold-copper mineralization on the target (Figure 1).

ML25-012 & -013 were drilled from the same location 52m north of ML25-010 & -011. Both holes were drilled at a 300^o azimuth and -45^o and -60^o dips, respectively. Both holes intersected a broad, up to 150m, zone of calc-silicate altered siltstone and marl with disseminated to fracture controlled pyrrhotite-arsenopyrite-chalcopyrite mineralization and anomalous gold and copper values. The most significant mineralization is associated with zones of increased fracturing, veining, and brecciation and include 12.5m of 0.735 g/t Au & 0.26% Cu from 16.5m depth and 5m of 2.13 g/t Au & 0.99% Cu from 85m depth in ML25-012. The lower 5m zone of Au mineralization occurs within a broader interval of significant Cu mineralization of 41.15m of 0.72% Cu from 83m depth; incl. 3.25m of 2.19% Cu from 120.9m depth. Mineralization in ML25-013 includes 4m of 1.11 g/t Au from 17m depth, 12.02m of 1.84 g/t Au & 0.42% Cu from 39.98m depth, and 3m of 1.49 g/t Au & 1.04% Cu from 124m depth. Similar to ML25-012, the lower gold intercept is contained within a broader zone of copper mineralization of 20m of 0.61% Cu from 108m depth: incl. 8m of 1.06% Cu from 117m depth.

ML25-014 & -015 were drilled from the same location 232m east of ML25-012 & -013. Both holes were drilled at a 300^o azimuth and -45^o and -52^o dips, respectively. ML25-014 returned 25m of 2.97 g/t Au from 137m depth; incl. 3m of 19.56 g/t Au from 137m depth. The mineralization is associated with disseminated to fracture controlled arsenopyrite – pyrrhotite (+/- chalcopyrite) mineralization within strongly calc-silicate altered siltstone/sandstone and mafic sills. The most significant gold mineralization corresponds to a structural zone associated with increased fracturing/veining and brecciation, multiple generations of arsenopyrite mineralization, and coarse Bi-Te minerals. ML25-015 was designed to undercut the high-grade mineralization in ML25-014, but the hole was lost before reaching target depth.

ML25-019 & -020 were drilled from the same location, 250m south of ML25-010 & -011. Both holes were drilled at a 300^o azimuth and -45^o and -60^o dips, respectively, and intersected three subvertical zones of gold and copper mineralization. Gold values were consistently anomalous across the zones with the best values returning from ML25-020 and include 1.9m of 9.91 g/t Au from 128.1m depth and 5m of 1.88 g/t Au from 147m depth. Additionally, both holes returned significant copper intercepts in the lowest zone and include 14.45m of 0.54% Cu from 166m depth; incl. 1.45m of 1.28% Cu from 179m depth from ML25-019 and 26m of 0.35% Cu from 220m depth; incl. 5m of 0.73% Cu from 240m depth from ML25-020. It should also be noted that the lower Cu-Au zone is along the projection of mineralized structures intersected in ML25-010 to -013 to the north.

ML25-022 & -023 were drilled from the same location 38m south of ML25-010 & -011. Both holes were drilled at a 300^o azimuth and -45^o and -70^o dips, respectively. Both holes intersected broad zones (up to 90m of strongly calc-silicate altered siltstone, marl, and gabbro. ML25-022 returned multiple discreet intercepts including 4m of 1.43 g/t Au & 0.29% Cu from 9m depth, 1.9m of 61.45 g/t Au & 0.34% Cu from 29.1m depth, 5.05m of 1.98 g/t Au from 38.95m depth, and 10m of 4.64 g/t Au & 0.41% Cu from 51m depth; incl. 6m of 6.84 g/t Au & 0.53% Cu from 53m depth. ML25-023 also returned multiple intercepts including 9m of 1.10 g/t Au & 0.17% Cu from 26m depth, 0.5m of 141 g/t Au from 63.75m depth, and 7m of 2.01 g/t Au & 0.65%Cu from 83m depth). The intervals from both holes are correlated and confirm subvertical structural controls on gold mineralization on the Skarn Ridge target.

Bueno

A total of 2,322.27m over 13 drill holes were completed on the Bueno target. To date results have been received for ten holes, including previously announced holes ML25-001 to -006⁽¹⁾. Gold and/or mineralization was intercepted within all holes received to date and correspond to a series of NNE trending structural zones cutting calc-silicate to hornfels altered shale, sandstone, siltstone, and mafic sills/dikes with disseminated to vein controlled pyrrhotite, pyrite, chalcopyrite, arsenopyrite, and, locally, Bi-Te mineralization.

The most significant mineralization from the new results were returned from ML25-018 and ML25-021. ML25-018 is in the T4 area at the southern end of the Bueno target and is a 40m step-out to the south of previously announced mineralization intercepted in ML25-005 / -006. The hole was drilled at an azimuth of 300 and dip of -50 and returned 4.75m of 1.18 g/t Au & 0.61% Cu from 24.20m depth. ML25-021 is in the T6 area, 285m northeast of T4, and returned 1m of 9.66 g/t Au from 121m depth. The hole was drilled at an azimuth of 300 and dip of -45 and was targeting gold copper mineralization reported within a historic trench.

Prospecting Results

Results for 73 rock grab and chip samples have been received from prospecting and geological mapping activities across the ML Property. The results ranged from trace to 109 g/t Au, trace to 136 g/t Ag, trace to 0.64% Cu, trace to 2.93% Pb, and trace to 2.42% Zn. Grab samples are selected sampled and may not be representative of underlying mineralization. Results for an additional 29 samples are pending and includes sampling conducted on trend of the new Tess Zone discovery. Highlights of prospecting results received to date are summarized below:

Figure 6: ML Property Target Areas with 2025 Rock Samples

Skarn Ridge

A total of 25 samples were collected from the Skarn Ridge target area and include samples up to 12.8 g/t Au. The 12.8 g/t Au sample was collected from outcrop on the ridgeline at the northeastern margin and consisted of strongly calc-silicate altered sandstone with fine grained disseminated arsenopyrite-chalcopyrite and NE and EW oriented, arsenopyrite filled veins and fractures. This is significant because the sampling was conducted beyond the limits of 2025 drilling and indicate the potential for additional mineralized structures in the Skarn Ridge area.

Rubble

Three samples from outcrop/subcrop of intrusive with E-W trending, subvertical, sheeted quartz-tourmaline-arsenopyrite veins were collected from the ridgeline on the SE margin of the Rubble target. The samples returned values of 0.395 g/t Au, 1.89 g/t Au, and 10.4 g/t Au and demonstrates a minimum of 400m of vertical continuity of mineralization on the target. Future work on the target will focus on vectoring in on areas with the highest vein densities for potential drill targeting.

Rubble North

Seven samples were collected from a previously unexplored area north of Rubble Lake and returned samples of 57.8 g/t Au and 109 g/t Au from strongly silicified and brecciated siliciclastic rocks with quartz – arsenopyrite veins and, locally, massive arsenopyrite. The sample are associated with strongly elevated As, Bi, and Te. The area lies approx. 750m north of Skarn Ridge and was targeted based on the projection of mineralized structures on Skarn Ridge to the NNE. This is significant because it demonstrates the potential for both strong vertical and lateral continuity on mineralized structural trends and highlights the potential for new discovery’s in previously un/under explored portions of the property.

2025 ML Drill Program

The 2025 drill program on the ML Property has been completed and includes 39 holes over 6648.91 m, testing seven target areas (Table 3). The program was completed on budget, finishing 1648.91m higher than the originally planned 5,000 program. To date, assays have been received for 24 of the 39 holes and include ML25-012 to 23 discussed above as well as previously released results on the North Vein – Tess, Skarn Ridge, Bueno, Rubble, and Java target areas. Analysis results for individual samples received to date range from trace to 379 g/t Au, from trace to 283 g/t Ag, and from trace to 11.70% Cu. The reported intervals are drilled widths and there is not currently enough data to accurately determine true thickness.

Assay Methodology & QA/QC

The diamond drilling on the ML Property consisted of NTW size core and was cut in half on site using a diamond saw. One half of the core was submitted for analysis, and the other half was held as retention in the original core box. The analytical work on the ML project was performed by AGAT Labs, an internationally recognized analytical services provider, located in Calgary, Alberta. All rock and core 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 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.
