Vancouver, British Columbia--(Newsfile Corp. - November 12, 2026) - Prospector Metals Corp. (TSXV: PPP) (OTCQB: PMCOF) (FSE: 1ET0) ("Prospector" or the "Company") today provided a progress update on the fully funded drill program at its ML Project, Yukon including final assays from a scissor-hole (ML26-85) through the TESS Trend yielding 5.91 g/t Au over 22.06m (from 46.52m) including 14.32 g/t Au over 8.58m (from 60m). New drilling has also successfully extended TESS an additional 50m to the SW with hole ML26-68 yielding 3.12 g/t Au over 11.31m (from 62.88m) and hole ML26-70 yielding 10.79 g/t Au over 2.24m (from 87m).

Prospector has also discovered the new "Rubble" gold trend located 3km SW of the TESS trend. ML26-123 is the first ever hole at Rubble and yielded several intercepts including 13.0 g/t Au over 0.51m (from 21.34m) plus 1.52 g/t Au over 4.63m (from 50.63m). Surface mapping and prospecting has successfully traced the Rubble Trend for at least 100m before being covered by thin overburden. New prospecting results from the Rubble Trend yielded assays ranging from 9.65 g/t Au to 93.8 g/t Au and averaging 45.6 g/t Au. Structural indicators also suggest the presence of several stacked or sub parallel altered zones along the Rubble Trend.

Dr. Rob Carpenter, Ph.D., P.Geo., Co-Chairman, President and CEO of Prospector commented: "The 2026 drill campaign has only scratched the surface of a district scale, high-grade gold system at ML. Drilling at TESS has confirmed a structurally controlled gold system that remains open along trend and to depth and results from our regional or reconnaissance drilling substantiate the presence of multiple high-priority structural trends across the project. We now have a stronger understanding of the gold system at ML, and our 2027 program will benefit greatly from data collected this season"

The ML Project represents an early-stage, high-grade and near-surface opportunity which is easily accessible and located nearby excellent infrastructure. Assays for 52 holes are pending and are expected in the coming weeks and will include the first ever drill results from several newly identified gold trends such as NIT, Lorrie, Pebble, Camp Valley and ML North. Prospector has a current cash position of over $36,000,000 sufficient to complete drilling at it's flagship ML Project, Yukon, for several years without requiring any additional funding.

Prospector has posted a pre-recorded webinar hosted by CEO Rob Carpenter and VP Exploration Jodie Gibson, where they will discuss the results from todays release. Click on the following: https://youtu.be/uSnmD0zlfHM

Summary

High-grade core at TESS confirmed: Scissor-hole (ML26-85) drilled through the TESS Trend yielding 5.91 g/t Au over 22.06m (from 46.52m) including 14.32 g/t Au over 8.58m (from 60m). Hole ML26-83 also yielded 5.83 g/t Au and 1.31% Cu over 8.79m (from 30.51m) including of 15.27 g/t Au and 4.38% Cu over 2.16m (from 60m).

TESS step-out drilling continues to expand to SW: New drilling has also successfully extended TESS an additional 50m to the SW with hole ML26-68 yielding 3.12 g/t Au over 11.31m (from 62.88m) and hole ML26-70 yielding 10.79 g/t Au over 2.24m (from 87m).

New drill discovery at "Rubble" highlights district-scale system at ML: New "Rubble" gold trend is a prospective NE-trending zone located 3km SW of the TESS trend. ML26-123 is the first ever hole at Rubble and yielded several intercepts including 13.0 g/t Au over 0.51m (from 21.34m) plus 1.52 g/t Au over 4.63m (from 50.63m). Surface mapping and prospecting has successfully traced the Rubble Trend for at least 100m before being covered by thin overburden. New prospecting results from the Rubble Trend yielded assays ranging from 9.65 g/t Au to 93.8 g/t Au and averaging 45.6 g/t Au. Structural indicators also suggest the presence of several stacked or sub parallel altered zones along the Rubble Trend.

Project-wide prospecting and sampling: Prospector collected 547 surface rock samples. Priority was given to areas of the project where no previous drilling has been completed to guide new drill targets for 2027. Results for all 547 samples will be released once final assays are received. Soil sampling was also completed in unworked portions of the project, and several high-priority targets have emerged. Notably, the high-grade "Chai" trend characterized by soil results up to 2.13 g/t Au.

2026 ML Drill Program

A total of 100 holes for 20,980 meters were drilled on the ML Project in 2026 testing nine target areas including TESS, Pebble, Nit, Rubble North, Phoenix, Bueno, ML North, Camp Valley, and Lorrie targets. To date results have been received on 48 of the 100 holes including 40 holes on the TESS trend and adjacent areas, 7 holes on the Phoenix target, and 1 hole on the Rubble target. Individual results for samples discussed in this release reach up to from trace to 147.2 g/t Au, to 147.2 g/t Ag, and to 6.07% Cu.

The remainder of the TESS holes consistently intercepted zones of alteration, veining, and localised brecciation, but were not strongly mineralized and returned anomalous results with values up to 2.53 g/t Au and 0.66%Cu.

TESS Discussion

Drilling in 2026 has successfully defined the TESS Zone over at least 400m along trend and to 175m depth, remaining open in all directions. Mineralization is hosted in a tabular, northeast trending and steep south dipping structural corridor which appears to have a true thickness ranging from 15-25m. Within this envelope, an "hourglass" shaped high-grade plunging core has now been assay confirmed in at least 1 hole on every drill section over 150m (section spacing of 25m), and there are indications for multiple plunging high-grade shoots. Mineralization on TESS is associated with calc-silicate alteration and/or quartz-sericite-clay alteration of conglomerate, grits, and lamprophyre - diorite dikes with disseminated to fracture-vein controlled sulfide mineralization consisting of pyrrhotite/pyrite, arsenopyrite, chalcopyrite, bismuth-tellurium minerals, and, locally, visible gold. The alteration and mineralization is focused along a northeast trending, steeply south dipping, structural corridor, with the highest-grade mineralization occurring where the structural zone intersects favorable lithologic units within the core of an E-W trending fold hinge, forming plunging shoots.

A series of holes were placed along the NE projection of the TESS structural corridor (NE of ML26-046). These holes confirmed continuity of the NE structures and consistently had zones of intense quartz-sericite alteration with variable sulfide mineralization but only returned anomalous results for gold. Based on our updated structural model for TESS which incorporates surficial geologic/structural mapping and oriented drill core measurements, the current interpretation is that these northeastern holes were drilled above and to the north of our key structural intersections and associated high-grade plunging shoots of mineralization. The TESS corridor is still considered open along trend in both directions and to depth. Additional drilling is planned in 2027 to test the continuity of TESS in all directions.

Rubble North

The Rubble North target is located 3.7km southwest of TESS along the western margin of the Mike Lake stock. Prospecting on the target in 2025 included samples that returned 57.8 and 109 g/t Au⁽² of quartz-arsenopyrite veins and breccias near the intersection of E-W and NE trending structures. Follow up surface mapping and prospecting in 2026 successfully traced the Rubble trend for at least 100m with rock sampling returning six subcrop samples ranging from 9.65 - 93.8 g/t Au (averaging 45.6 g/t Au). An additional zone of mineralization is also noted 125m to the northwest and returned rock samples of 10.8, 22.1, & 28.4 g/t Au, indicating the potential for stacked or sub-prallel zones of mineralization along the trend. A total of 32 samples were collected in the target area and ranged from trace to 93.8 g/t Au.

One hole was drilled as an initial test on the target in 2026 with hole ML26-123 returning several intercepts including 13.0 g/t Au over 0.51m (from 21.34m) plus 1.52 g/t Au over 4.63m (from 50.63m). The hole was drilled beneath the 2025 prospecting samples, and the target is considered a priority for follow up drilling in 2027.

Phoenix

The Phoenix zone is located 4.4km southwest of the TESS Zone and was a focus of drilling during the 2025 ML program. Mineralization on Phoenix is associated with a series of NNE trending structural zones cutting a strongly calc-silicate alterted sequence of calcareous siltstone, sandstone, marl, and shale units, and is associated with quartz-carbonate veining, brecciation, and strong sulfide mineralization consisting pyrrohtite-pyrite, arsenopyrite, chalcopyrite, and, locally, Bi-Te minerals with occasional specks of visible gold. Highlights from the 2025 drilling include:

• ML25-010: 2.11 g/t Au, 8.6 g/t Ag, & 0.48% Cu over 45.65m from 44m depth⁽¹⁾

• ML25-014: 2.97 g/t Au over 25m from 137m depth⁽²⁾

• ML25-022: 61.45 g/t Au over 1.9m from 21.9m depth⁽²⁾

• ML25-024: 2.04 g/t Au, 8.7 g/t Ag, & 0.42% Cu over 27m from 24m depth; and
                    4.33 g/t Au, 9.9 g/t Ag, & 0.5% Cu over 19m from 57m depth⁽³⁾

Drilling on Phoenix in 2026 consisted of 11 holes totalling 2,207m. Results have been received for seven holes (ML25-059, 065, 069, 074, 074B, 077, & 079). The holes were designed to fill in a 140m gap and confirm continuity of mineralization between ML25-025 and ML25-027. All the holes collared in calc-silicate altered marl and siltstone with veining, localised brecciation, and localised sulfide mineralization, but quickly transitioned into unaltered marl/silstone within 20m of the collar, and only returned anomalous results for gold and copper, up to 1.75 g/t Au & 0.59% Cu. The current interpretation is that the holes collared into the western edge of the mineralized structural corridor and additional drilling should be collared further east to fully test the trend. In addition, the the holes drilled through the unaltered marl/siltstone unit and intercepted zones of strongly calc-silicate altered siltsonte, sandstone, and shales with pyrrhotite-arsenopyrite-chalcopyrite, and locally, Bi-Te mineralization. Analysis results were anomalous, but no consistent zones of mineralization were intercepted, with the best values including 4.94 g/t Au over 1m from 147m depth in ML26-065 and 0.55% Cu over 2.44m from 153m depth in ML26-079.
