North Pine

North Pine Project

Advancing a Tier-One U.S. Critical Minerals Opportunity.

The North Pine Project in Valley County, Idaho positions Pioneer Minerals at the heart of one of North America’s most important critical-minerals districts. The project covers approximately 18.4 km² across the Springfield and Silver Cliffs prospect areas and sits immediately adjacent to Perpetua Resources’ Stibnite Gold–Antimony Project and near Resolution Minerals’ Horse Heaven Antimony Project and the Johnson Creek Tungsten–Antimony Mill.

The North Pine Project hosts multiple high-potential mineral systems, including a high grade scheelite tungsten skarn at Springfield and a gold, silver, and antimony epithermal system at Silver Cliffs. Recent sampling has confirmed standout grades, with tungsten up to 2.98% WO₃ and gold up to 7.75 g/t Au at Springfield, and gold–silver–antimony results up to 3.89 g/t Au and 34.8 g/t Ag with strong Sb at Silver Cliffs.

A recently completed high-resolution airborne magnetic and radiometric survey has now delivered the structural and lithological framework needed to advance North Pine into its next exploration phase. Upcoming work will integrate geophysics, geochemistry, and field mapping to define clear drill-target corridors across this emerging, district-scale critical-minerals opportunity.
