Prospector Drilling at TESS Yields 5.91 g/t Au over 22.06m including 14.32 g/t Au over 8.58m

Prospector Metals Corp. (ticker PPP) has reported final assay results from its fully funded 2026 drill program at the ML Project in the Yukon, highlighting significant high-grade gold intercepts at the TESS and Rubble trends. The TESS trend has been extended an additional 50m to the southwest, with key holes confirming a structurally controlled, district-scale high-grade gold system that remains open in all directions. Additionally, a new "Rubble" gold trend was discovered 3km southwest of TESS, with initial drilling and surface sampling indicating multiple stacked or sub-parallel altered zones with high-grade potential.
Drilling at the TESS trend has defined the zone over at least 400m along the trend and to 175m depth, with the true thickness of the structural corridor estimated at 15-25m. Key intercepts from the program include:
- ML26-085 (Scissor-hole): 5.91 g/t Au over 22.06m from 46.52m, including 14.32 g/t Au over 8.58m from 60m, including 147.2 g/t Au over 0.5m from 60m.
- ML26-083: 5.83 g/t Au, 30.5 g/t Ag, & 1.31% Cu over 8.79m from 30.51m, including 15.27 g/t Au, 105 g/t Ag, & 4.38% Cu over 2.16m from 34.34m.
- ML26-070: 10.79 g/t Au over 2.24m from 87m, including 14 g/t Au over 1.04m from 87m.
- ML26-068: 3.12 g/t Au over 11.31m from 62.88m, including 21.31 g/t Au over 1.19m from 73m.
- ML26-073: 0.91 g/t Au, 13.81 g/t Ag, & 0.81% Cu over 12.80m from 131.5m, including 1.59 g/t Au, 52.67 g/t Ag, & 3.15% Cu over 2.30m from 140.9m.
- ML26-078: 3.01 g/t Au, 64.6 g/t Ag, & 2.77% Cu over 0.72m from 145.28m, and 4.18 g/t Au, 15.31 g/t Ag, & 0.88% Cu over 3.9m from 153.5m, including 19.2 g/t Au, 44.5 g/t Ag, & 2.44% Cu over 0.61m from 156.79m.
- ML26-075: 3.51 g/t Au over 2.48m from 101.8m.
At the newly discovered Rubble trend, located 3km SW of TESS, the first hole drilled, ML26-123, returned 13.0 g/t Au over 0.51m from 21.34m, plus 1.52 g/t Au over 4.63m from 50.63m. Surface sampling at the site has been traced for at least 100m, with 6 subcrop samples returning 9.65 - 93.8 g/t Au (avg 45.6 g/t Au). Structural indicators suggest stacked or sub-parallel altered zones.
Drilling at the Phoenix target involved seven holes (ML26-059, 065, 069, 074, 074B, 077, & 079) designed to fill a 140m gap. Holes collared into calc-silicate altered marl/siltstone but transitioned to unaltered units quickly, returning only anomalous results (up to 1.75 g/t Au & 0.59% Cu). The best results included 4.94 g/t Au over 1m from 147m in ML26-065 and 0.55% Cu over 2.44m from 153m in ML26-079. Interpretation suggests the holes collared the western edge of the corridor, with additional drilling planned further east.
The 2026 program totaled 100 holes for 20,980 meters. Assays have been received for 48 of 100 holes (40 TESS, 7 Phoenix, 1 Rubble), with 52 holes pending and expected in the coming weeks. Prospector Metals Corp. maintains a cash position of over $36,000,000, sufficient to complete drilling for several years without additional funding.
Assay work was conducted by Bureau Veritas (BV) and ALS Laboratory. BV utilized PRP70-250 prep, FA430 (30g fire assay with AAS finish), and MA200 (multi-element), with re-analysis for >10g/t Au via 50g Fire Assay with Gravimetric finish. ALS utilized Prep-31B prep, Au-AA23 (30g fire assay with AAS finish), and ME-MS61 (multi-element), with re-analysis for >10g/t Au via 50g Fire Assay with Gravimetric finish. QA/QC procedures included the insertion of certified standards, blanks, and duplicates. Jodie Gibson, P.Geo., VP Exploration, is the Qualified Person for the project.
"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," said Dr. Rob Carpenter, Co-Chairman, President and CEO.
