Perpetua Resources has provided an update on exploration activities at the company's Stibnite Gold Project in central Idaho.
The 2026 Exploration Drilling Program is now complete with over 16,000 meters of core drilling across the project. The program's objectives included upgrading in-pit and near-pit inferred resources, extending mineralization along strike, testing key underground targets, and following up on discoveries from the 2025-2026 drill program.
Initial assays from the Fiddle target returned 109.7 meters grading 3.2 g/t gold, 1.1% antimony in hole SB633, beginning at 189 meters downhole. SB633 represents one of the broadest continuous intervals of gold and antimony mineralization returned to date from Stibnite while also exhibiting grades more than double the Project's life-of-mine average.
Additional assays came from 3 holes: SB637, which extended mineralization 110 meters to the north, and SB643 and SB646, which were drilled from a pad to the north of SB633. An additional 21 holes were drilled along strike of SB633. Two subsequent holes, SB665 and SB671, were drilled to the south and are awaiting assay. Core logging identified both holes as having similar style mineralization to hole SB633, including abundant stibnite and sulfides within the mineralized zones.
Follow-up drilling from the Clark Tunnel Fault Zone continued to demonstrate near-surface, high grades including 25.4 meters of 4.5 g/t gold from 13 meters downhole (SB606) and 25.0 meters of 2.3 g/t gold from 18 meters downhole (SB605). Antimony and tungsten assay results for these holes are currently pending.
"Given their close proximity to the permitted Yellow Pine pit, Fiddle and the CTFZ were prioritized as key targets for the 2026 exploration program," said Jon Cherry, President and CEO of Perpetua Resources. "At Fiddle, our initial hole returned broad, continuous mineralization at significant gold and antimony grades which confirm it as an important new discovery. Meanwhile, drilling continues to reinforce the CTFZ as a near-surface, high-grade target on the eastern extent of the Yellow Pine pit. We're pleased with the results from our recent drilling which align with our objectives of expanding our currently defined resource base and extending our compelling production profile."
