Olympio Metals (ASX:OLY) has discovered a previously unknown adit approximately 500m along strike from the historical Conjecture Mine at its Jacknife Silver Project in Idaho, US.
The company says field mapping has identified the new target on a patented mining claim. The claim’s patented status allows immediate testing as part of the maiden drilling program now underway.
The discovery sits along the interpreted Conjecture Shear Zone and could extend the mineralised strike length to approximately 1km.
It sits roughly 500m beyond the historical foreign resource estimate at Conjecture, which contains 8.22 million ounces (Moz) of silver. No mining records exist for the newly located adit, leaving its depth and scale unknown.
“The scout team are doing a great job with the first boots-on-the-ground exploration at Jacknife aiming to generate new targets to increase the project scale,” Managing Director Sean Delaney says.
“This new adit target indicates that the mineralised Conjecture Shear Zone may extend for at least another 500m to the southwest, greatly increasing the scale potential of the project.”
The company has completed rock-chip sampling at historical mine locations and soil sampling along selected ridges between the Conjecture and Weber shear zones. Results are expected in the coming weeks.
Olympio’s partner Scout Discoveries is providing technical and operational support for the exploration program.
The Jacknife Project comprises 135 hectares of patented mining claims in Idaho’s Silver Valley region, where six mines have produced more than 3.2Moz of silver at an average grade of 12.7 ounces per tonne (about 435 grams per tonne).
The maiden drilling program of approximately 1,500m targets ‘high-grade’ silver mineralisation at the historical Conjecture Mine.
Antimony and silver feature on the United States Geological Survey’s 2025 Critical Minerals List, against the backdrop of the US Strategic Critical Minerals Reserve, backed by up to US$12 billion ($17.2 billion) in financing and private capital.
Olympio Metals is an Australian explorer advancing gold, silver, and critical mineral projects across Canada and the US.
