Banyan Announces 7 Million Ounce Gold Updated Mineral Resource Estimate, AurMac Project, Yukon, Canada

VANCOUVER, BC / ACCESSWIRE / February 7, 2024 / Banyan Gold Corp. (the "Company" or "Banyan") (TSXV:BYN)(OTCQB:BYAGF) is pleased to announce an updated Mineral Resource Estimate (the "MRE" or the "Mineral Resource") prepared in accordance with National Instrument 43-101, Standards for Disclosure for Mineral Projects ("NI 43-101") for the AurMac Project, Yukon Territory. ‎

The updated MRE comprises an Inferred Mineral Resource of 7.0 million ("M") ‎ounces ("oz") of gold (as defined in the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition ‎Standards for Mineral Resources & Mineral Reserves incorporated by reference into NI 43‑101).

The pit constrained MRE is contained in two near/on-surface deposits: The Airstrip and Powerline¹ deposits in the road accessible AurMac Project.

"With the AurMac Resource now at 7.0 Moz gold; 6.2 Moz in the Powerline Deposit alone, we can focus on delineating higher-grade zones, increase the confidence in the resource and further de-risk the project," stated Tara Christie, President and CEO. "Metallurgical studies to date have demonstrated that Powerline mineralization is amenable to conventional mining processes, including Carbon in Pulp ("CIP") and Carbon in Leach ("CIL"), flotation and heap leaching. Looking at the grade sensitivities, at a 0.60 g/t cut-off there are potentially 4 Moz at a grade of 1 g/t across AurMac, which highlights both the robust nature of the deposit as the cut-off grade is increased along with the potential for higher grade zones."
______________________________________________________________________

¹ _{Includes Aurex Hill deposit (Aurex Hill was included as a standalone deposit in previous May 18, 2023 MRE). The 2023 drill program connected Powerline and Aurex Hill deposits into a single deposit, now defined as Powerline.}

The updated MRE is summarized below in Table 1:

Table 1: Pit-Constrained Inferred Mineral Resources - AurMac Project^{(1)(2)(3)(4)(5)}

Notes to Table 1:

1. The effective date for the MRE is February 6, 2024.
2. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, changes in global gold markets or other relevant issues.
3. The CIM Definition Standards were followed for classification of Mineral Resources. The quantity and grade of reported Inferred Mineral Resources in this estimation are uncertain in nature ‎and there has been insufficient exploration to define these Inferred Mineral Resources as an ‎Indicated Mineral Resource and it is uncertain if further exploration will result in upgrading them to an ‎Indicated or Measured Mineral Resource category.
4. Mineral Resources are reported at a cut-off grade of 0.30 g/t gold for all deposits, using a US$/CAN$ exchange rate of 0.75 and constrained within an open pit shell optimized with the Lerchs-Grossman algorithm to constrain the Mineral Resources with the following estimated parameters: gold price of US$1,800/ounce, US$2.50/t mining cost, US$5.50/t processing cost, US$2.00/t G+A, 80% gold recoveries, and 45° pit slopes.
5. The number of tonnes and ounces was rounded to the nearest thousand. Any discrepancies in the totals are due to rounding effects; rounding followed the recommendations as per NI 43-101.

A NI 43-101 Technical Report supporting the updated Mineral Resource will be filed on SEDAR at www.sedar.com within 45 ‎days of this release.‎ The pit outlines used to constrain the MRE are shown in Figure 1. Detailed images of the Mineral Resource model, including an interactive 3D model and additional information can be found at: https://www.banyangold.com/projects/aurmac/

Powerline Deposit

The drill data for the Powerline deposit is comprised of 954 drill holes, representing an increase of 107 holes from the May 18, 2023 MRE.

There are several geologic controls on gold mineralization as per the current geologic understanding of the Powerline deposit. The mineralization model is comprised of eight (8) parallel and undulating mineralized zones. These zones trend east-west with a plunge of 5° to the west and dip of 10° to the north. The bulk of the gold resources within the updated MRE are hosted within quartz veins that dip 13° to 17° toward an azimuth of 329° to 335°.

The most common sampling length of the Powerline deposit is 1.5 metres ("m"), accounting for more than 50% of the sample data and is the composite length. Capping of high-grade outliers was carried out for each mineralized zone and ranged from 4.0 g/t gold to 11.0 g/t gold.

The estimation of gold grades into a block model was carried out with the Ordinary Kriging ("OK") technique on capped composites with the resultant block model comprised of a parent block size of 10m (easting) x 10m (northing) x 5m (elevation) and a sub-block size of 1m (easting) x 1m (northing) x 1m (elevation).

At a 0.30 g/t gold cut-off, the pit-constrained, Inferred Mineral Resources for Powerline are 312.2 million tonnes at an average gold grade of 0.61 g/t for a total of 6,158,000 ounces of gold. Cut-off grade sensitivities for the Powerline deposit are presented in Table 2.

Airstrip Deposit

The Airstrip deposit is delineated by 139 drill holes, representing no increase of drill holes from the May 18, 2023 MRE. Topographic control was from a detailed LIDAR survey dataset.

There are several geologic controls on gold mineralization as per the current geologic understanding of the Airstrip deposit. The Airstrip lithological model is comprised of eight (8) east-west oriented units, with six (6) of the units dipping at approximately 40° to the south. The bulk of the gold identified within the updated MRE are hosted within a calcareous package; a roughly 90-metre-thick east-west striking zone dipping approximately 40° to the south.

The most common sampling length of the Airstrip deposit is 1.5 m accounting for approximately 45% of the sample data; all composites were constructed at this interval. Capping of high-grade outliers was based on lithological domains and varied from 3.0 g/t gold to 9.0 g/t gold.

The estimation of gold grades into a block model was carried out with the OK technique on capped composites and the resultant block model comprised of a block size of 10m (easting) x 10m (northing) x 5m (elevation) and sub-block size of 1m (easting) x 1m (northing) x 1m (elevation). Density was calculated from a total of 418 measurements from the drill core. The average density per lithology type was assigned to the corresponding blocks.

At a 0.30 g/t gold cut-off, the pit-constrained, Inferred Mineral Resources for the Airstrip deposit are 35.2 million tonnes at an average gold grade of 0.75 g/t for a total of 845,000 ounces of gold. Cut-off grade sensitivities for the Airstrip deposit are presented in Table 3.

Quality Assurance, Quality Control Measures and Data Verification

The reported work was completed using industry standard procedures, including a quality assurance/quality control ("QA/QC") program consisting of the insertion of certified standards, duplicates and 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 NI 43-101 Technical Report‎. The qualified persons detected no significant QA/QC issues during review of the data.

A robust system of standards, ¼ core duplicates and analytical 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 geological data in the MRE was verified by Ginto Consulting Inc. ("Ginto") as being accurate to the extent possible and to the extent possible all geological information was reviewed and confirmed. Ginto made site visits to the AurMac Project on September 15^th, 2018, November 27^th, 2019, August 30^th to 31^st, 2021 and November 5^th, 2022, and observed Banyan's drilling and sampling techniques, as well as viewed AurMac drill core. Ginto confirms that the assay sampling and QA/QC sampling of core by Banyan provides adequate and good verification of the data and believes the work to have been done within the guidelines of NI 43-101.
