Banyan Gold Continues to Delineate High-Grade in Powerline Southwest, AurMac Project, Yukon, Canada
Banyan Gold Continues to Delineate High-Grade in Powerline Southwest, AurMac Project, Yukon, Canada
VANCOUVER, BC / ACCESS Newswire / July 13, 2026 / Banyan Gold Corp. (the "Company" or "Banyan") (TSXV:BYN)(OTCQB:BYAGF) is pleased to announce it has intersected additional high-grade gold ("Au") mineralization in the Powerline Deposit ("Powerline") southwest of the main high-grade core. These diamond drill intersections highlight potential to upgrade domains in a portion of Powerline, AurMac Project ("AurMac"), Yukon, Canada.
Highlights from Powerline West:
AX-26-865 - 1.55 g/t Au over 5.4 metres ("m"); and
2.08 g/t au over 4.1m, within 0.86 g/t Au over 31.4m,
1.15 g/t Au over 12.6m, and
1.24 g/t Au over 11.6m,
all within 0.55 g/t Au over 151.3m
AX-26-855B - 2.44 g/t Au over 5.0m,
including high-grade of 15.76 g/t Au over 0.6m
AX-26-859 - 1.49 g/t Au over 8.8m,
including high-grade of 14.40 g/t Au over 0.8m
"Banyan Gold continues to intersect high-grade mineralization as we drill the Powerline Deposit, where our objectives are to convert inferred mineral resources to indicated and to drill beneath the conceptual pit to increase the quantity of inferred ounces at depth," stated Tara Christie, President and CEO. "Multiple high-grade intervals, like those intersected in AX-26-865, indicate the potential to upgrade mineralized domains both laterally and within section as we continue infilling Powerline. Additionally, there is strong potential for discovering new continuous, high-grade zones, including Powerline Southwest, which continues to demonstrate the potential to intersect new skarn horizons associated with sheeted veins and high-grade gold mineralization. Our drill program is ahead of schedule with over 33,000m completed out of our 70,000 m program."

Figure 2: Cross-section 466550mE from Powerline Southwest at AurMac. Mineralized domains are overlaid on the lithologic model. Mineralized domains are open up-dip and at depth, with potential to expand the mineralized envelope as well as convert significant un-estimated blocks that fall within the conceptual pit. Current Mineralized domains being tested during indicated infill drilling (magenta outline) have potential to be significantly upgraded as well with high-grade intervals. Lithologic domains in Powerline are dominated by metasedimentary rocks of various compositions, typically mica-chlorite schists with varying calcareous content. Domains in this section are: CLSR_4 and 5 - chlorite sericite schist; CSCH_1 and 3 - calcareous schist; sch_2 - heterogenous schist. The MRE block model is constrained by mineralized domains and the lithologic domains. Mineral Resource blocks are 10m x 10m x 5m. Only blocks >0.30 g/t Au cutoff and within the US$3,500/oz Au conceptual pit shell are included in the MRE.

Sheeted veins in the high-grade zone from 198.8-202.9m is spatially associated with calcareous metasedimentary rocks with replacement style sulphide mineralization. Within larger lithologic domains there are typically several different lithologies present, eg. AX-26-865 198.65-202.77m there are repeated intervals of calcsilicate-altered calcareous-schist with skarn-style replacement mineralization and muscovite-quartz schist with varying degrees of silicification/bleaching and sheeted quartz vein emplacement.

Analytical Method and Quality Assurance/Quality Control Measures
The reported work was completed using industry standard procedures, including a quality assurance/quality control ("QA/QC") program consisting of the insertion of certified reference materials, field duplicates and coarse blanks into the sample stream and utilizing certified independent analytical laboratories for all assays. Additionally, historic QA/QC data and methodology on the AurMac Project were reviewed and will be summarized in the Technical Report. The qualified persons detected no significant QA/QC issues during review of the data.
A robust system of standards, core duplicates and coarse blanks, was implemented in all Banyan drilling programs and was monitored as chemical assay data became available. All control samples were within accuracy and precision thresholds required to meet data quality standards. These control samples amounted to approximately 10% of all samples submitted to analytical laboratories.
All diamond drill core was systematically logged and photographed by Banyan geology personnel. All core samples (HTW and NTW diameter) were split on-site at Banyan's core processing facilities. Once split, half samples were placed back in the core boxes with the other half of split samples sealed in poly bags with one part of a three-part sample tag inserted within. Samples were delivered by Banyan personnel or a dedicated expediter to the Bureau Veritas, Whitehorse preparatory laboratory where samples are prepared and then shipped to Bureau Veritas's Analytical laboratory in Vancouver, B.C. for pulverization and final chemical analysis.
Core splits reported in this news release were analysed by Bureau Veritas of Vancouver, B.C., utilizing the four-acid digestion ICP-ES 35-element MA-300 or ICP-ES/MS 59-element MA-250 analytical package with FA-450 50-gram Fire Assay with AAS finish for gold on all samples. Samples returning >10 g/t Au were reanalysed by fire assay with gravimetric finish on a 50g sample (FA-550). High-grade samples with documented visible gold are also analysed using metallic screen fire assay (FS-652). Samples returning >200 g/t Ag (MA250 or MA300) were analysed by multi-acid digestion ICP-ES MA370. If samples returned > 1,500 g/t Ag, they were analysed by fire assay with gravimetric finish on a 50g sample (FA550). If samples returned > 10,000 g/t Ag, they were analysed by fire assay 2g sample (FA501). Bureau Veritas is an accredited lab following ISO/IEC 17025:2017 SCC File Number 15895. A robust system of standards, ¼ core duplicates and blanks has been implemented in the 2026 exploration drilling program and is monitored as chemical assay data becomes available.
