Stuhini Completes Mini Bulk Sample at Ruby Creek's Silver Surprise Zone
Stuhini (OTCQB: STXPF) extracted a 1,585‑pound mini bulk sample from the Silver Surprise Zone at its 100%‑owned Ruby Creek Project near Atlin, BC on October 6, 2025. The hand‑dug, two‑person, two‑day sample targets metallurgical testing of bonanza‑grade silver mineralization that previously returned rock samples up to 16,030 g/t Ag (with four samples >10,000 g/t Ag).
Metallurgical testing in Atlin will focus on gravity separation and mineralogy under metallurgist Rino Mihoc; results will determine feasibility of larger bulk samples in 2026. The zone hosts at least three ~1 m veins exposed up to 180 m and remains open along strike and at depth.
Stuhini (OTCQB: STXPF) ha estratto un campione di mini bulk da 1.585 libbre dalla Silver Surprise Zone nel progetto Ruby Creek di proprietà al 100% vicino ad Atlin, BC, il 6 ottobre 2025. Il campione hand- dug, per due persone, di due giorni mira ai test metallurgici di una mineralizzazione di argento di livello bonanza che in passato ha restituito campioni di roccia fino a 16.030 g/t Ag (con quattro campioni >10.000 g/t Ag).
I test metallurgici ad Atlin si concentreranno sulla separazione per gravità e sulla mineralogia sotto la supervisione del metallurgo Rino Mihoc; i risultati determineranno la fattibilità di campioni bulk più grandi nel 2026. La zona ospita almeno tre vene di ~1 m esposte fino a 180 m e rimane aperta lungo la scia e in profondità.

Oktober 2025 ein 1.585 Pfund schweres Mini-Bulk-Probenstück aus der Silver Surprise Zone im zu 100 % eigentümergeführten Ruby Creek Project in der Nähe von Atlin, BC entnommen. Die handgegrabene, von zwei Personen in zwei Tagen durchgeführte Probe zielt auf metallurgische Tests einer Bonanza-Grade-Silbermineralisierung ab, die zuvor Proben bis zu 16.030 g/t Ag geliefert hat (mit vier Proben >10.000 g/t Ag).
Die metallurgischen Tests in Atlin werden sich auf Gravitationstrennung und Mineralogie konzentrieren, unter der Leitung des Metallarurs Rino Mihoc; die Ergebnisse werden die Machbarkeit größerer Bulk-Proben im Jahr 2026 bestimmen. Die Zone beherbergt mindestens drei ~1 m breite Adern, die bis zu 180 m freiliegend sind, und bleibt längs der Strike-Variante sowie in der Tiefe offen.

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
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.

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.
