Banyan Gold Confirms New Gold-Silver Discovery at Seattle Creek with 5.70 g/t
Au and 544 g/t Ag over 0.5m, Nitra Project, Yukon
August 25, 2026, TSX-V: BYN
VANCOUVER, BC, August 25, 2026 - Banyan Gold Corp . (the "Company" or "Banyan")
(TSXV: BYN ) (OTCQB: BYAGF) is pleased to announce that the first drillhole at the
Seattle Creek zone on the greenfields Nitra Project (“Nitra”), has confirmed a new high-
grade gold and silver mineralized system 25 km west of the AurMac Deposit. Only the top
95 metres of the 600-metre hole have been assayed to date. Seattle Creek is located on
claims 100% owned by Banyan with no underlying royalties and is the second of eleven
exploration targets being drill tested in 2026 on Banyan’s broader 830 sq km AurMac and
Nitra land packages in the Mayo Mining District, Yukon (The discovery at the first
greenfield target, Roaring Fork and the discovery at Seattle Creek was announced on
July 28, 2026, with visible gold and photos of drill core at Seattle Creek.)
Highlights from Seattle Creek Zone at Nitra:
• NT-26-006 – 0.91 g/t Gold and 27.01 g/t Silver over 12.1 m from 41.7 m;
o including 4.04 g/t Au over 1.4 m and 3.32 g/t Au over 1.4 m; and within the
4.04 g/t Au interval, 0.5 m returned 5.70 g/t Au and 544 g/t Ag.
*Note: Only assays from the top 95 m of the 600 m NT-26-006 drillhole have been
received to date; assays for the lower portion of the hole are pending.
“Initial assays from the Seattle Creek zone have returned high-grade gold and silver
mineralization, adding another mineralized zone to our greenfields Nitra project,” stated
Tara Christie, President and CEO. “Diamond drillhole NT -26-006 intersected multiple
occurrences of visible gold hosted in extensional quartz veins with associated bismuth
sulphosalts and arsenopyrite. Together with the other geologic indicators, Seattle Creek
has the potential to expand with follow-up drilling. The discovery of additional visible gold
identified in drillhole NT -26-002, with assays pending, also supports the potential to
extend the Roaring Fork Zone.”
In June 2026, Banyan commenced its greenfields exploration diamond drilling program
at Nitra. The program is designed to test 11 regional targets identified through new
geophysical surveys, soil geochemical anomalies, placer-mining history and prospecting.
More than 7,500 m of drilling is planned to use three helicopter -supported drills to
minimize the initial footprint and accelerate target testing. Nitra benefits from an extensive
road network established by previous placer mining activities. The objective of the
program is to identify potential satellite deposits and additional expressions of Red uced
1
Intrusion-Related Gold Systems (" RIRGs") west of AurMac, where more than 95% of
Banyan’s district-scale land package remains untested by drilling.
“The large , annealed shear zone , brecciated quartz veins, and multiphase sulphide
mineralization, all spatially associated with high-grade gold mineralization in extensional
quartz veins, are encouraging indicators of a potential larger mineralizing system at the
Seattle Creek and Roaring Fork zones ,” stated Duncan Mackay, V ice President
Exploration. “ While visible gold can be an encouraging indicator, it does not always
correlate with assay grade . We are encouraged that the visible gold at Seattle Creek is
associated with high -grade assays and are planning follow -up drilling to test the extent
and geometry of the system.”
Figure 1: Location of the Seattle Creek Zone (Figure 2) in Nitra, approximately 25km west of AurMac and 2.5km north
of Roaring Fork Zone.
At Seattle Creek, a combination of soil geochemical anomalies (Gold, Bismuth, Arsenic)
and geophysical signatures (resistive anomaly) were used to identify the target. These
targeting indicators were combined with proximal placer mining in the creek drainage to
locate and prioritize the targets. Mineralization at Seattle Creek is predominantly hosted
in large extensional quartz vein hosting bismuth sulphosalts, arsenopyrite, pyrite, and
2
locally sphalerite (Figure 5), and foliation sub -parallel shear veins hosting bismuth -
sulphosalts, arsenopyrite, pyrite. Mineralization at Seattle Creek is spatially associated
with annealed (cemented) faults with brecciated quartz vein material and wall rock
entrained in a pyrite rich ground mass (Figures 7-9). Long lived/reactivated structures are
strong indicators for min eralization potential with complex structural regimes and fluid
pathways providing opportunities for mineralizing fluids to permeate the country rock and
precipitate gold.

Figure 3: Cross Section A-B in Figure 2 – Seattle Creek Zone – Nitra. Numerous visible gold occurrences in potential
mineralized zone between 36m and 53m primarily hosted in metasedimentary and metavolcanic rocks. Stratigraphy is
dipping moderately (~35-45 degrees) slightly east of south (approx. 165 -170 degrees). Extensional veins are dipping
moderately (30-50 deg) slightly west of north. Major annealed shear zone s at 110-115m (Figure 7 and 8 ) and 364-
367m (Figure 9). The orientation of annealed shear zones is yet to be confirmed and will require additional drilling.

Figure 7: Zone of intensely sheared/deformed rock in drillhole NT -26-006 (Figure 3). Spatial association with visible
gold mineralization from 36-53m in NT -26-006 is a strong indicator of potential for a more widespread mineralizing
system at Seattle Creek.
Figure 8: Brecciated quartz shear vein hosting bismuth sulphosalts, arsenopyrite, sphalerite, and pyrite. Late
brecciation and mineralization of existing shear veins indicate a long -lived structure which underwent reactivation.
Brecciation and mineralized ground mass may indicate high fluid flux through the system; reactivated structures may
act as major fluid pathways for concentrating regionally pervasive mineralizing fluids.
