Bayhorse Silver (OTCQB: BHSIF) has received final IP Survey results for the eastern side of their Silver Mine, revealing five significant low-resistance IP targets. The nearest target is located 78m east and 57m below the historic Sunshine stope. The mineralized zone now extends to over 600m in strike length.

Three of these anomalies align with the historic Sunshine, Junction, and Big Dog stopes, which previously yielded approximately 25,000 tons of direct shipping grade material each. These historic stopes contained high-grade silver (up to 240 ounces per ton) along with critical minerals including copper, antimony, and zinc.

The company is preparing to drill the first IP target, situated 18m under the mine access road. The IP survey also identified a significant chargeability zone with a N-S strike of approximately 400m and a vertical extent of 75-100m. The exploration model suggests the possibility of porphyry copper mineralization from an underlying shallow pluton as the source of the rhyolite-hosted mineralization.

Bayhorse Silver (OTCQB: BHSIF) ha ricevuto i risultati finali del sondaggio IP per il lato orientale della loro Miniera d'Argento, rivelando cinque significativi obiettivi a bassa resistenza. L'obiettivo più vicino si trova a 78m a est e 57m sotto il vecchio stope Sunshine. La zona mineralizzata si estende ora per oltre 600m in lunghezza.

Tre di queste anomalie si allineano con i vecchi stope Sunshine, Junction e Big Dog, che in precedenza avevano prodotto circa 25.000 tonnellate di materiale di qualità per spedizione diretta. Questi stope storici contenevano argento di alta qualità (fino a 240 once per tonnellata) insieme a minerali critici come rame, antimonio e zinco.

La società si sta preparando a perforare il primo obiettivo IP, situato a 18m sotto la strada di accesso alla miniera. Il sondaggio IP ha anche identificato una significativa zona di carica con un'estensione N-S di circa 400m e un'estensione verticale di 75-100m. Il modello di esplorazione suggerisce la possibilità di mineralizzazione di rame porfirico da un plutone superficiale sottostante come fonte della mineralizzazione ospitata nel riolite.

Bayhorse Silver (OTCQB: BHSIF) hat die endgültigen IP-Umfrageergebnisse für die östliche Seite ihrer Silbermine erhalten, die fünf bedeutende Niedrigwiderstands-IP-Ziele offenbart. Das nächstgelegene Ziel befindet sich 78m östlich und 57m unterhalb des historischen Sunshine-Stollens. Die mineralisierte Zone erstreckt sich jetzt über mehr als 600m in der Länge.

Drei dieser Anomalien stehen im Einklang mit den historischen Stollen Sunshine, Junction und Big Dog, die zuvor etwa 25.000 Tonnen Material in Versandqualität geliefert haben. Diese historischen Stollen enthielten hochgradiges Silber (bis zu 240 Unzen pro Tonne) sowie kritische Mineralien wie Kupfer, Antimon und Zink.

Das Unternehmen bereitet sich darauf vor, das erste IP-Ziel zu bohren, das sich 18m unter der Zufahrtsstraße zur Mine befindet. Die IP-Umfrage identifizierte auch eine signifikante Ladungszone mit einem N-S-Strecken von etwa 400m und einer vertikalen Ausdehnung von 75-100m. Das Explorationsmodell deutet auf die Möglichkeit einer porphyrischen Kupfermineralisierung von einem darunter liegenden flachen Pluton als Quelle der in Rhyolith gehosteten Mineralisierung hin.

Vancouver, British Columbia--(Newsfile Corp. - March 31, 2025) - Bayhorse Silver Inc, (TSXV: BHS) (OTCQB: BHSIF) (FSE: 7KXN) (the "Company" or "Bayhorse") reports that final IP Survey results have been received for eastern side of the Bayhorse Silver Mine.

Final IP data received shows five IP low-resistance targets. The nearest IP target to the historic mined stopes starts 78 m (257 ft) to the immediate east of and 57 m (188 ft) below the previously mined historic Sunshine stope. The Sunshine, Junction, and Big Dog stopes extend over a strike length of 160 m (528 ft), were up to 10 m (33 ft) wide, and between 7 – 9 m (23 – 30 ft) in height, and up to 38 m (125 ft) in length.

The five significant low resistance IP targets (Figure 1) extend over a N-S distance of 450 m (1485 ft) of which three anomalies lie on strike with, and in close proximity to the historic, mined, Sunshine, Junction, and Big Dog stopes, and the partially mined Goldilocks zone, over a nearly 600m (1980 ft) strike.

Work is under way preparing to drill the first IP drill target, that lies 18 m (60 ft) under the Bayhorse Mine access road. Drilling will commence from the lower adit portal, that is 25 m (82 ft) from, and 3 m (10 ft) above the IP target. The IP target, 36m (118 ft) across, is estimated to be similar in size to the historic Sunshine and Junction stopes (Figure 1), where approximately 25,000 tons of direct shipping grade material was mined from each and shipped by rail to the historic Tacoma smelter. (US Metals, 1924).

Significant volumes of sulfosalts containing high grade silver, up to 240 ounces per ton, along with the critical minerals, copper, antimony and zinc, were mined from these three stopes, prior to the Bayhorse Silver Mine being closed in late 1984 due to low silver prices (<$5 per ounce) (Silver King Mines, 1984). Silver, copper, antimony and zinc mineralization has been identified in veins and stockworks west of the Junction stope over a strike length of between 130 – 170 m (427 – 557ft) (National Instrument 43-101 inferred resource of 6.3 m ounces of silver at a grade of 21.65 opt ((673 g/t) (Turner et al. 2018).

Bayhorse CEO Graeme O'Neill comments that, "the close proximity of the three new IP targets on strike east of the historic Sunshine, Junction and Big Dog high-grade silver stopes, that extends westerly through the partially mined Goldilocks zone, and the newly developed high grade drift zone, west of the Big Dog, looks like pearls on a string, and as mineralization is found on surface, 300 m (990 ft) west of the Mine portal, it suggests that more "mineralized pods" will be discovered underground to the west."

The IP results by S.J. V Geophysics has, in addition to the low-resistance zones, also identified a significant chargeability zone (Figure 3) with a N-S strike of +/- 400 m (1320 ft) with a vertical extent of between 75 – 100 m ( 248 – 330 ft) within the VTEM geophysics signature within the rhyolite hosted copper and silver rich Bayhorse Silver Mine deposit. A priority is to extend the IP geophysical survey onto the Pegasus project to better identify additional drill targets as soon as ground conditions permit.

The Bayhorse exploration model holds that the rhyolite hosted silver-copper-zinc-antimony rich mineralization at the Bayhorse Silver Mine could have its source in an underlying shallow pluton that may host porphyry copper mineralization. The rhyolite extends from the Pegasus Project and its VTEM anomaly that lies 1500 m (5000 ft) east of the Bayhorse Mine workings in the State of Idaho, under the Snake River, to under the Bayhorse Mine.

While the Bayhorse mineralization is mainly composed of sulfosalts, Bayhorse senior consulting geologist, Dr. G.E. Ray, advises there are many cases worldwide where there are sulfide rich deposits at depth that pass up to sulfosalt rich epithermal mineralization at shallower depths. The 228 m (752 ft) breccia zone encountered may indicate the presence of massive sulfides/copper porphyry at depth.
