Stuhini Completes Mini Bulk Sample at Ruby Creek's Silver Surprise Zone
Stuhini Completes Mini Bulk Sample at Ruby
Creek's Silver Surprise Zone
Vancouver, British Columbia--(Newsfile Corp. - October 6, 2025) -
Stuhini Exploration Ltd.
(TSXV:
STU) (OTCQB: STXPF) (WKN: A2PLBV) ("Stuhini" or the "Company") is pleased to announce the
extraction of a
1,585-pound mini bulk sample
from the
Silver Surprise Zone
at its 100%-owned
Ruby Creek Project
, near Atlin, British Columbia. Extraction of the mini-bulk sample was completed at
surface with hand tools along one of the Silver Surprise Zone veins by a two-person team over a two-day
period.
The objective of this mini-bulk sample is to test and advance metallurgical understanding of the high-
grade silver mineralization identified during prior Ruby Creek Project exploration programs. (See press
release dated
April 6, 2021
and
February 22, 2022
). Analysis of the refined silver from this preliminary
test will determine the likelihood of completing larger bulk samples in 2026. A bulk sample is a large,
representative quantity of material—extracted for detailed testing to determine its composition,
properties, and commercial potential.
"
With growing interest in silver globally, both from investors and the broader commodity markets —
Silver Surprise Zone stands out as one of the most compelling silver zones on the property," said
Meredith Eades, President and CEO. "With multiple samples over 10,000 grams per tonne silver and
room to grow, we're excited to be advancing metallurgical work and further define the mineralized trend.
This is an important step toward unlocking the full silver potential at Ruby Creek."
Silver Surprise Zone Highlights:
Located along strike of the broader Adera structural corridor.
Contains the highest grade silver samples encountered on the Ruby Creek Project to date, placing
it firmly in bonanza-grade category.
28 samples between 1,000-16,030 grams per tonne ("g/t") silver ("Ag") and 4 over 10,000g/t Ag
including:
16,030 g/t Ag
14,179 g/t Ag
12,980 g/t Ag
Mineralization hosted in massive sulphide-bearing quartz veins.
3 parallel veins to date ~1 metre ("m") in width up to 180m in length at surface.
Remains open along strike and at depth.

Surprise Zone (highlighted in yellow) hosts some of the highest-grade samples on the property and lies
in the central-northern area, along strike of the Adera Corridor (~9 kilometres apart, center to center).

Mineralization at Silver Surprise Zone occurs in at least three quartz-sulphide veins and vein-breccias
that are each ~1m wide within the main body of the Surprise Lake Batholith. The veins are exposed
semi-continuously for a length from 180m, 50m and 30m respectively before they are submerged
beneath the talus. The veins are clustered within 200m laterally striking ~220° and align with the Adera
structural corridor and are sub-vertical.
They appear to remain open at depth as well as along strike in
both directions.
There are also anomalous float samples uphill from the current occurrences on the talus
slope.

Petrographic has shown the silver mineralization to occur predominantly as Ag-Sn sulphides (canfieldite)
as well as acanthite and rare native silver with galena, pyrite, +/- sphalerite and arsenopyrite.

This mini-bulk sample will be processed, analyzed and monitored in Atlin under the direction of Rino
Mihoc, a seasoned metallurgist with over 20 years hands-on experience. For this program, Rino will
oversee the metallurgical test design, with a focus on gravity separation and advanced mineralogical
analysis. Results from the program will help inform future drill targeting, mineralogical modeling, and
development planning.
Further geological mapping and geochemical sampling are underway to test potential extensions along
the mineralized trend. Maps and imagery showing the sample site and structural features will be
released as data becomes available.
Historically, the Atlin region is known for the
past producer 'Atlin Ruffner Silver Mine', located 23 road km
from Atlin and approximately 12 km west of the Silver Surprise Zone. Circa 1951 it is reported this mine
produced a shipment of
44 tons of ore grossing 7 ounces gold, 5,343 ounces silver, 36,197 pounds
lead, and 5,824 pounds of zinc.

About the Ruby Creek Project:
The 29,734-hectare Ruby Creek Project is road accessible and located 14 kilometres (km) east of Atlin,
British Columbia ("BC"). There are 48 different documented mineral occurrences on the Property, of
which 16 are gold-related, with 7 significant gold placer creeks. The Property also hosts the Ruby Creek
Molybdenum deposit, which hosts a measured and indicated pit constrained resource of 433 million lbs
molybdenum using US$15.00 per lb molybdenum prices and a 0.02% cut-off grade. (See news release
dated
March 15, 2022
). Stuhini owns 100% of the Ruby Creek Project.
