Banyan Gold Drills 1.90 g/t Au over 17.3m, Adds Fourth Drill Rig and Extends High-Grade Domains in Core of Powerline Deposit, Yukon, Canada
VANCOUVER, BC, AB / ACCESS Newswire / October 21, 2025 / Banyan Gold Corp. (the "Company" or "Banyan") (TSXV:BYN)(OTCQB:BYAGF) is pleased to announce it has intersected high-grade gold at surface in the core of the Powerline Deposit ("Powerline") at its AurMac Project ("AurMac") in the prolific Tombstone Belt, Yukon, Canada.
Selected Highlights Demonstrate Continuity of High-Grade in Core of Central Powerline Deposit:
AX-25-697 - 2.69 g/t gold ("Au") over 11.8 metres ("m") within 0.65 g/t gold over 72.5m; including 29.3 g/t Au over 0.4m, 21.04 g/t Au over 0.4m, and 2.26 g/t Au over 3.4m.
AX-25-700 - 3.07g/t Au over 3.6m within 0.69 g/t Au over 29.3m, and 1.90 g/t Au over 17.3m; including 33.00 g/t Au over 0.8m
AX-25-706 - 16.68 g/tAu over 1.1m within 2.39 g/t Au over 8.1m at surface
AX-25-709B - 2.55 g/t Au over 6.4m within 0.85 g/t Au over 22.9m
High-grade gold in drillholes AX-25-697, 700, 706, and 709B, as outlined above, highlight the potential for very high-grade gold intervals in Powerline and continue to reinforce continuity in the core of the deposit and confirm new 3D modelling of the high-grade mineralized domains. These intersections also have the potential to convert inferred ounces from the current Mineral Resource Estimate ("MRE") (Table 3) into indicated resources in the Powerline Deposit (Figure 1; Tables 1 and 2). To date, the Company has drilled over 30,000m (130 holes) on AurMac this year, with current drill program ongoing.
"With our recent $31.4-million strategic investment by Alpayana we have upsized our drill program to 40,000 m and have added a fourth drill rig," stated Tara Christie, Banyan President and CEO. "Our modelling and drilling suggests that the deposit is open in all directions, confirming the +1g/t Au zones and potentially extending the zones beyond the previously known mineralization."
"Our drilling in the core of Powerline (Figure 1) continues to confirm continuity of refined and high-grade mineralized domains," added Duncan Mackay, Vice President of Exploration. "With mineralized domains open down-dip (Figure 2) we also have the potential to add additional high-grade ounces while converting inferred ounces to indicated. We continue to intersect visible gold, in zones of high-grade mineralization (Figures 3 and 4), and throughout the Powerline deposit."
Figure 1: Plan map of the northeast portion of the Powerline Deposit. High-grade mineralization is associated with emplacement of sheeted veins in favourable host rocks, primarily based on rheology; more brittle rocks are favourable hosts for sheeted vein emplacement. Cross-section line for Figure 2 shown by gold line.
Sheeted-veins with visible gold, bismuth sulphosalts, and arsenopyrite are localized in higher concentrations in zones of more competent, brittle rocks (Figures 3 and 4). Veins are centimetre to decimetre in scale, generally with trace to 2% accessory minerals (bismuth sulphosalts and arsenopyrite). As rheology of the stratigraphy controls vein emplacement, detailed modelling is being carried out to refine the litho-structural model of the deposit and help define more refined mineralized domains. Many mineralized domains are open down-dip, with potential for more domains to be identified outside of the current mineralised envelope.
Figure 2: Cross-section of the Powerline Deposit at 466500 E. Refined mineralized domains (in magenta) intersected in the drillholes in this release reinforce continuity of high-grade mineralization. Down-drip extensions of mineralized domains have potential to convert additional waste blocks into ore as well as flatten the conceptual pit floor.
