ORIGINAL: Banyan Announces 6.2 Million Ounce Gold Resource Estimate for the AurMac Property, Yukon, Canada

2023-05-24 09:53 ET - News Release

VANCOUVER, BC / ACCESSWIRE / May 24, 2023 / 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 Aurex ‎and McQuesten properties (together, the "AurMac Property")‎1 ‎located in the Mayo Mining ‎District, approximately 56 kilometres ("km") northeast from the village of Mayo, Yukon, and 356 ‎km north of Whitehorse, Yukon. ‎

The updated MRE comprises a total Inferred Mineral Resource (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) of 6.2 million ‎ounces of gold on the near-surface, road accessible AurMac Property.

The pit constrained Mineral Resource Estimate is contained in three near/on-surface deposits: The Airstrip, Powerline and Aurex Hill. The MRE is summarized below.

"This Mineral Resource update is an increase of over 2 million ounces or over 50% from the 2022 MRE," stated Tara Christie, President and CEO, "This was accomplished with 50,000 metres of drilling completed in a single season. With all three deposits remaining open, Banyan continues to focus on growth and has already drilled 15,000 metres subsequent to this Mineral Resource Update in our ongoing 2023 exploration program."

Notes: ‎

  1. The effective date for the Mineral Resource is May 18, 2023.
  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 0.25 g/t Au for the Airstrip and Powerline and 0.3 g/t Au for the Aurex Hill 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, UD$2.00/t G+A, 80% heap leach recoveries, and 45° pit slope.2
  5. The number of tonnes was rounded to the nearest hundred thousand. The number of 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 Mineral Resource Estimate will be filed on SEDAR at www.sedar.com within 45 ‎days of this release.‎ The pit outline on-surface of the MRE is shown in Figure 1 below.

About the AurMac Property

The AurMac Property is held by the Company under earn-in/option agreements (the "Option ‎Agreements") with StrataGold Corporation, a 100% owned subsidiary of Victoria Gold Corp. (TSE: VGCX) ‎‎("Victoria Gold"). The ‎Company has the right to earn up to a 100% interest in the AurMac Property, subject to royalties, ‎pursuant to the terms and conditions of the Option Agreements.3 ‎ ‎

The Airstrip, Powerline and Aurex Hill deposits contained within the AurMac Property are all on and near-surface deposits and potentially open pit mineable, with low expected strip ratios. The AurMac Property is located just 40 km from Victoria Gold's open pit, heap leach mine and 10 km from Alexco's mill facility at the High-Grade silver deposits of the Keno Hills District. The AurMac Property lies on existing transportation infrastructure (Main Yukon Government Highway System) and the all-season road to Victoria Gold's Eagle Mine. The Aurex Hill, Airstrip and Powerline deposits are within 1 km of each other and within 50 metres ("m") of year-round access roads, have 3-phase powerlines and benefit from cellular communications.

Airstrip Deposit

The Airstrip deposit is delineated by 139 drill holes, representing an increase of eight (8) drill holes from the May 17, 2022 MRE. Topographic control was derived 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 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 Au to 9.0 g/t Au.

The estimation of gold grades into a block model was carried out with the Ordinary Kriging ("OK") technique on capped composites and the resultant block model comprised of a block size of 10 m (easting) x 10 m (northing) x 5 m (elevation) and sub-block size of 1 m (easting) x 1 m (northing) x 1 m (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 0.25 g/t Au cut-off, the pit-constrained, Inferred Mineral Resources are 41.2 million tonnes at an average gold grade of 0.68 g/t for a total of 897,000 ounces of gold. Cut-off grade sensitivities for the Airstrip deposit are presented in Table 2.

  4. Mineral Resources are reported at a cut-off grade of 0.25 g/t Au, 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, UD$2.00/t G+A, 80% heap leach recoveries, and 45° pit slope.

Powerline Deposit

The drill data for the Powerline deposit is comprised of 504 drill holes, representing an increase of 338 drill holes from the May 17, 2022 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 six (6) 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 MRE are hosted within quartz veins that dip up to 13° toward 329°.

The most common sampling length of the Powerline deposit is 1.5 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 7.0 g/t Au to 15.0 g/t Au.

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

At a 0.25 g/t Au cut-off, the pit-constrained, Inferred Mineral Resources are 197.4 million tonnes at an average gold grade of 0.61 g/t for a total of 3,840,000 ounces of gold. Cut-off grade sensitivities for the Powerline deposit are presented in Table 3.

Aurex Hill Deposit

The drill data for the Aurex Hill deposit is comprised of 345 drill holes, representing an increase of 104 drill holes from the May 17, 2022 MRE.

There are several geologic controls on gold mineralization as per the current geologic understanding of the Aurex Hill deposit. The mineralization model is comprised of eight (8) parallel and undulating mineralized zones that trend east-west and have with a plunge of 5° to the west and dip of 20° to the north. The bulk of the gold resources within the MRE are hosted within quartz veins that dip up to 17° toward 335°.

The most common sampling length of the Aurex Hill deposit is 1.5 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 Au to 15.0 g/t Au.

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

At a 0.30 g/t Au cut-off, the pit-constrained, Inferred Mineral Resources are 74.3 million tonnes at an average gold grade of 0.60 g/t for a total of 1,444,000 ounces of gold. Cut-off grade sensitivities for the Aurex Hill deposit are presented in Table 4.

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 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 Property 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 resource estimate 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 property on September 15, 2018, November 27, 2019, August 30 and 31, 2021, and November 5, 2022, and observed Banyan's drilling and sampling techniques, and 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. Additional discussion on the AurMac Mineral Resource Model Data Verification will be included in the forthcoming NI 43-101 Technical Report to be filed on SEDAR within 45 days.

Qualified Persons

The updated Mineral Resource for the AurMac Property was prepared by Marc Jutras, P.Eng., M.A.Sc., Principal, Ginto Consulting Inc., a "Qualified Person" independent of the Company, as defined under National Instruction 43-101, Standard of Disclosure for Mineral Projects ("NI 43-101") who has reviewed and approved the contents of this release and has verified the data disclosed as it relates to the MRE.
