Banyan Provides Summary of 2025 Diamond Drill Program for the
Flagship AurMac Project, Yukon, Canada
May 14, 2026, TSX-V: BYN
VANCOUVER, BC, May 14, 2026 - Banyan Gold Corp. (the "Company" or "Banyan")
(TSX-V: BYN) (OTCQB: BYAGF) is pleased to release the final drill results and provide
a comprehensive summary of the 2025 AurMac delineation drill program. The 42,000
metres (“m”) program included 178 drillholes at the AurMac Project, with the primary goal
of the 2025 drill program to maximize economic potential for the upcoming Preliminary
Economic Assessment (“ PEA”; expected second half of 2026) by targeting high -grade
domain and mineralized envelope extensions, and waste block conversion. Drilling took
place from March 27, 2026, to November 10, 2026. Drill results throughout AurMac
consistently intersected high-grade gold (“Au”) mineralization, including well mineralized
sheeted quartz vein domains hosting Bismuth-sulphosalts and visible gold throughout the
core of the Powerline Deposit (“Powerline”). Very high -grade gold mineralization
associated with sulphide replacemen t and skarn-style mineralization in the Airstrip
Deposit (“ Airstrip”) were intersected in a core high -grade contact zone between
calcareous metasedimentary rocks and a felsic aplite dyke . These findings follow up on
drilling conducted in 2024 (see news release dated February 19, 2025).
Assay highlights from this release:
• AX-25-692: 9.12 g/t Au over 1.5m within 0.78 g/t Au over 21.6m
AND 0.64 g.t Au over 15.6m
• AX-25-743: 0.90 g/t Au over 13.3m within 0.51 g/t Au over 25.9m
• AX-25-744: 2.59 g/t Au over 6.1m within 0.74 g/t Au over 26.3m
• AX-25-760: 1.00 g/t Au over 4.0m AND 0.7 1 g/t Au over 11.4m all within 0.43 g/t
Au over 58.4m
• AX-25-776: 0.82 g.t Au over 6.6m within 0.47 g/t au over 14.2m
• AX-25-790: 0.78 g/t Au over 16.8m within 0.5 g/t Au over 44.0m, including high
grade of 17.34g/t Au over 0.4m
“We are looking forward to incorporating the 2025 drill results into our upcoming Mineral
Resource Update and PEA, marking our first opportunity to speak about the economics
of the AurMac Project,” stated Tara Christie, President and Chief Executive Officer. “The
PEA will focus on the gold potential , while ongoing drilling of the exciting silver
intersections and metallurg ical work throughout 2026 will further define the silver
economics, potentially contributing to a future economic study.”

“Banyan was able to take full advantage of an expanded drill program of over 42,000m to
follow-up on high-grade zones intersected in 2024 , while supporting the upcoming PEA
through targeted drilling to convert in -pit waste blocks and expand high-grade domains
identified with the new 3D model,” stated Duncan Mackay, Vice President, Exploration.
“Drilling through 2025 further expanded the AurMac deposits, showcasing the potential
to connect the Airstrip and Powerline pits. We have identified areas where the conceptual
pit may be flattened and extended at depth, demonstrating the open nature of
mineralization, with 200-300m step outs hitting promising mineralization and visible gold
in several directions. In an exciting new dimension, we have successfully followed up on
bonanza-grade silver intersections in the core of Powerline and have identified at least
eight discrete Keno-style silver veins across the deposits.”

Airstrip Deposit:
Consistent high-grade drill intersections through 2025 reinforce the continuity of gold
mineralization associated with skarn-style sulphide replacement mineralization in Airstrip
and the potential of this near-surface deposit. The first visible gold intersected in Airstrip
is associated with skarn mineralization and is coincident with the highest-grade samples
we have seen at this deposit (13.4 g/t Au over 5.94m, including 41.1 g/t Au over 0.97m).
The potential of the high -grade contact zone in Airstrip is highlighted by samples in AX -
25-650 returning results such as 51.2 g/t Au over 0.63m, 32.7 g/t Au over 0.55m and 41.1
g/t Au over 0.97m (see news release dated June 25, 2025) . High-grade mineralization
was also intersected in approximately 200m down-dip step-outs in Cal 1 and Cal 2 on the
southern edge of Airstrip ( Figure 3; AX-25-799 – 7.04 g/t Au over 6.0m within 0.68 g/t
Au over 125.5m; see Banyan Gold News release dated February 8, 2026).

intersected in AX-25-799 and AX-25-807 in Airstrip represent large step-outs and down-dip extensions of the Cal 1 and
Cal 2 zones (see news released dated February 8, 2026). Drilling in Central Powerline successfully extended high -
grade mineralized domains at depth and supported continuity of domains and high -grade zones in th e core of the
deposit.

Powerline Deposit:
Drilling in 2025 successfully intersected high-grade intervals associated with mineralized
domains and sheeted-vein systems typical of Reduced Intrusion Related Gold deposits
(“RIRGs”) throughout the core of Powerline. With the improved 3D model for Powerline,
mineralized domains can be more effectively targeted with opportunities to convert waste
blocks; extend domains and flatten or deepen the conceptual pit floor; potentially extend
high-grade portions of the main deposit at AurMac ; and support the upcoming PEA in the
second half of 2026.
In Powerline, s heeted quartz-veins with visible gold, bismuth sulphosalts, and
arsenopyrite are localized in higher concentrations in zones of more competent, brittle
rocks. 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.
Continued drilling at Powerline has successfully confirmed mineralized domains in the
core of Powerline (Figure 5), refined and extended mineralization between the Powerline
and Airstrip main pits (Figure 3) and extended mineralization with potential to convert
waste blocks in the southwest of Powerline.

Figure 5: Cross -section 466700 . Drillholes AX -25-743, -692 and -790 extend and confirm continuity of high -grade
domains in the core and northern portions of Powerline.
Gold mineralization in southwest Powerline is consistent with mineralization seen in the
core of Powerline; gold mineralization is associated with discordant sheeted quartz veins
hosting sulphosalts and sulphides (predominantly sphalerite, arsenopyrite) , and is
preferentially hosted in silicified/altered host rocks. Additional step -out drilling has
intersected high -grade mineralization with potential to extend mineralized domains
outside the conceptual pit boundary (Figure 6).

Figure 6: Cross-section 466100E in southwest Powerline. Drillholes AX -25-760 and -776 indicated potential for new
mineralized domains intersected in step-out drilling. Coarse bismuth sulphosalts and visible gold have been intersected
in the area which warrants further expansion/exploration drilling.
Silver Mineralization:
The identification of high -grade silver potential along extended strike lengths in central
Powerline added a new dimension to the mineralization and metallogenic story for
AurMac.
Highlights from 2025 (see news release dated January 22, 2026) confirming the very
high-grade Keno-style silver mineralization in Powerline:
• AX-25-803 – 5,625 g/t Ag over 3.4m within 1,841 g/t Ag over 10.4m , with very
high-grade interval of 10,734 g/t Ag over 1.7m
• AX-25-790 – 110.7 g/t Ag over 0.8m within 22.06 g/t Ag over 5.7m
• AX-25-715 – 132 g/t Ag over 0.5m within 7.25 g/t Ag over 13.7m
