Stuhini Highlights High-Grade Tungsten Potential at Ruby Creek
Stuhini Highlights High-Grade Tungsten
Potential at Ruby Creek
VANCOUVER, BC
,
July 3, 2025
/CNW/ - Stuhini Exploration Ltd. (the "Company" or "Stuhini") (TSX-
V: STU and OTCQB: STXPF) is pleased to report the results of a comprehensive review of tungsten
mineralization at its 100%-owned Ruby Creek Project ("Ruby Creek" or the "Project"), located near
Atlin, British Columbia
. The review confirms the presence of a high-grade, structurally controlled
tungsten system that flanks the Company's existing 433-million-pound pit-constrained molybdenum
deposit. (1)
Meredith Eades
, President and CEO of Stuhini, commented: "Tungsten is increasingly recognized as
a strategic metal, essential to both industrial applications and national defense. Our review of the
Ruby Creek dataset has confirmed a robust and high-grade tungsten system flanking our existing
molybdenum deposit — an opportunity that's been largely overlooked until now. As we continue our
systematic approach to exploration, these results add a new layer of value to Ruby Creek and
reinforce our commitment to advancing critical mineral assets that align with future demand."

Tungsten System Overview
Mapping and sampling at Ruby Creek have outlined multiple tungsten-bearing structures forming a
broad halo around the Ruby Creek molybdenum deposit. These mineralized structures are
associated with northeast-southwest trending faults, veins, and shear zones that range from 0.1 to
1.75 metres thick and extend for hundreds to thousands of metres along strike. Primary tungsten
minerals identified include
wolframite
and
scheelite
.
A total of 188 samples returned >0.1% WO
, , with 40 samples exceeding 1% WO
and 3 returning
over 10%. These values occur along well-defined trends, suggesting strong structural control and
continuity of mineralization.

Target Zones and Historical Work
Stuhini's internal review has outlined
seven priority tungsten zones
with strike extents from 750
metres to 4.5 kilometres:

In addition,
anomalous tungsten in soils (20–500 ppm)
suggests further mineralized structures
may be present under till and soil cover along strike.
Next Steps
Stuhini plans to follow up with
detailed surface mapping and rock sampling
to refine targeting
across these structures and potentially identify new tungsten-bearing zones. The tungsten system
represents a previously underappreciated critical minerals component of the Ruby Creek Project and
will be incorporated into future targeting and project advancement plans.
About the Ruby Creek Project
The 29,734-hectare Ruby Creek Project is located approximately 14 km east of
Atlin, BC
, and is
road-accessible. The property hosts the
Ruby Creek molybdenum deposit
, which contains a
measured and indicated pit-constrained resource of 433 million pounds of
molybdenum
(using
US$15
/lb Mo and a 0.02% cutoff) and multiple additional mineral occurrences
including gold, silver, tungsten, and copper. Stuhini owns 100% of the Ruby Creek Project, subject to
a 1% NSR. (1)
