Vancouver, British Columbia, July 18, 2022 (GLOBE NEWSWIRE) — Asante Gold Corporation (CSE: ASE | GSE: ASG | FRANKFURT: 1A9 | U.S.OTC: ASGOF) (“Asante” or the “Company”) is pleased to announce preparation of an updated NI 43-101 Technical Report for the Bibiani Gold Mine (“Bibiani” or the “Project”), operated by Mensin Gold Bibiani Limited (“Mensin Gold Bibiani”), a 90% owned Ghana subsidiary of Asante (the “2022 Technical Report”). The 2022 Technical Report has been prepared to the level of confidence of a Pre-Feasibility Study and will be filed on the Company’s SEDAR profile ( within 45 days.

The 2022 Technical Report when filed will supersede the previous Bibiani JORC/NI 43-101 submissions by Resolute Mining Limited (“Resolute”) in 2018 (the “Resolute 2018 Technical Report”) and by Asante in November 2021, which were based on geological modelling for development of an underground mine (the “2021 Technical Report”). By re-configuring to open pit mining, Asante increased the 2021 Project Measured + Indicated Mineral Resources by 26.4% to 2.29 Moz. The Mineral Resource estimate included in the 2021 Technical Report does not include significant gold mineralization outlined beneath the current pit shells (see Figures 1 to 4 below).

In July 2018, Resolute, released an updated feasibility study for Bibiani (see Resolute’s ASX Announcement dated July 13, 2018) reporting JORC compliant Mineral Resources of 21.7 Mt at 3.6 g/t Au for 2.5Moz of gold, to be mined using underground methods to a depth of 475m. In November 2021, Asante released the 2021 Technical Report that was based on Resolute’s underground modelling and interpretations that considered open pit mining. It defined a 1.8M oz resource to be mined using open pit mining practices to a depth of 350m. The mineralized material from the Resolute 2018 Technical Report located below the pit bottom was not included in Asante’s 2021 Technical Report.

The 2022 Technical Report is based on updated geological data and resource modelling. It specifically reflects development of open pit mining plans, plus start of mining operation and processing facilities. The Measured and Indicated Mineral Resources have been increased to 2.29 Moz and are further classified as 1.95 Moz of Mineral Reserves. The open pit mine life has been increased from 6 years to 8.3 years, with more than 1.9 Moz of gold expected to be produced. The Bibiani Mine orebody remains open at depth and along strike. The Company continues with exploration at surface and will start an underground mine design project during Q4 2022, with a view toward commencing underground operations in 2024.
The 2022 Technical Report will include re-modelled and updated Mineral Resource and Mineral Reserve Estimates along with a detailed mining schedule and economic analysis relevant for an open pit mining operation. Asante plans to mine using staged cut-backs of the Bibiani Main Pit and two satellite pits, Walsh and Strauss.

Key highlights of the 2022 Technical Report, on a 100% owned basis, include:

  • Measured + Indicated Mineral Resources of 31.57MT at 2.25g/t Au (2.29 Moz) and Inferred Mineral Resources of 4.02Mt at 2.75 g/t Au (0.355 Moz)
  • Proved and Probable Mineral Reserves of 28.41Mt at 2.14 g/t Au (1.95 Moz)
  • Project Life of Mine (“LoM”) of 8.3 years (Open Pit)
  • Post-Tax IRR 43% and NPV (5%) of US$392 million at US$1,703/oz gold
  • Cash costs US$823/oz
  • AISC US$1,222/oz
  • Total gold recovered 1.9 Moz
  • Payback Period of 2.0 years
  • Measured + Indicated Mineral Resources Bibiani Main Pit, include a 54% increase in tonnes and a 25% increase in ounces (Indicated portion)
  • Measured + Indicated Mineral Resources Walsh Pit, include a 16% increase in tonnes, a 45% increase in grade, and a 68% increase in ounces

The mine design and schedule results in a mining inventory of 28.41Mt at 2.14g/t Au. The LoM is 8.3 years at a steady state of 4.0Mtpa from 2025. The total material mined reaches a maximum of approximately 8Mtpm with an average LoM strip ratio of 17.

The 3Mtpa Bibiani mine process plant has been refurbished and updated to 2022 standards, and 24 hour per day operation has started. Current plans are to treat approximately 3Mtpa of ore from 2022 – 2023, comprised of both fresh and oxide ore from the Bibiani Main and satellite pits. Asante plans to expand the processing capabilities to 4.0Mtpa throughput by 2025 to meet the requirements of the LoM Plan.

“We purchased the Bibiani Gold Mine in August 2021 and have recently announced the start of operations. We are pleased to report that our initiatives to conduct extensive near mine exploration, resume open pit operations and refurbish the Process Plant, have resulted in a significant increase to mine life and expected gold production at Bibiani. We continue our work to define and capture opportunity for significant upside at Bibiani. The Company continues with surface exploration activity and anticipates extending open pit mine life. An underground mine design program will start in Q4 2022, with a goal to start underground mining in 2024. These exploration, design and production initiatives are not considered in the 2022 Technical Report. Recently, we announced a forward gold financing agreement that will account for less than 30% of the next 12 months expected gold production at Bibiani. This agreement puts the Company on solid financial footing as we move forward,” stated Dave Anthony, President and CEO, who added, “Asante thanks the technical team of Mensin Gold Bibiani and principal consultants dMb Management Services Pty Ltd, BARA Consulting Pty Ltd and SNOWDEN Optiro for delivering the 2022 Technical Report ahead of schedule.”


Snowden Optiro have re-modelled the Mineral Resources to be applicable and pertinent to Mensin Gold Bibiani’s open pit operational plan. This Mineral Resource Estimate and associated Mineral Reserve Estimate supersedes all previous submissions (the Resolute 2018 Technical Report; 2021 Technical Report).

The effective date of the Mineral Resource estimate is February 28, 2022 and comprises the Bibiani Main Pit and Satellite Pits (Walsh and Strauss), which have been combined into a global Mineral Resource estimate as presented below.

Summary of Mineral Resource at a 0.5 g/t Au cut-off as at February 28, 2022
  Measured and Indicated Inferred
  Tonnes Au Grade Au Content Tonnes Au Grade Au Content

Bibiani Main Pit 30.20 2.23 2.170 3.90 2.69 0.338
Satellite Pits 1.37 2.62 0.116 0.12 4.57 0.020
TOTAL 31.57 2.24 2.286 4.02 2.74 0.358


  1. Tonnes and ounces have been rounded and this may have resulted in minor discrepancies.
  2. Mineral Resources are not Mineral Reserves.
  3. Mineral Resources are reported inclusive of any Mineral Reserves that may be derived from them.
  4. 1 troy ounce = 31.1034768g.
  5. A 0.5g/t gold cut-off has been applied and constrained by a RPEEE US$1,950 (metal price) Resource pit shell.
  6. A density of 2.75t/m³, 2.50t/m³ and 2.0 t/m³ on fresh, transition and oxidized sediments have been applied respectively.
  7. Geological losses and depletions have been applied.
  8. Inferred Mineral Resources have a great amount of uncertainty as to their existence and as to whether they can be mined economically. It cannot be assumed that all or part of the Inferred Mineral Resource will ever be upgraded to a higher category.

The Mineral Resource Model is supported by an updated lithological model, analytical data, recent infill and exploration diamond drilling and geophysical logging and survey results. The data used as inputs to the model have been collected and compiled at a high standard supporting the conclusion that the Project is a high-quality mineral asset.

The Mineral Reserve Estimate has been prepared by BARA Consulting using CIM, 2014 and procedures for classifying the reported Mineral Reserves were undertaken within the context of NI 43-101.

The Mineral Reserves were derived from the Mineral Resource block models and estimates. The Mineral Reserves are based on the Measured and Indicated Mineral Resources that have been identified as being economically extractable and which incorporate mining losses and the addition of waste dilution.

The mine design supporting the Mineral Reserve is based on an optimum pit shell using an US$1,850/oz Au price. The Mineral Reserve Estimate as at February 28, 2022 is presented in the following table.

Summary of Mineral Reserve as at February 28, 2022
  Tonnes Grade Contained Gold

  8. No Inferred Mineral Resources have been included in the Mineral Reserve estimate.
  9. Quantities are reported in metric tonnes.
  10. The input studies are to the prescribed level of accuracy.
  11. The Mineral Reserve estimates contained herein may be subject to legal, political, environmental or other risks that could materially affect the potential exploitation of such Mineral Reserve.

For readers to fully understand the information in this news release they should read the 2022 Technical Report in its entirety once available, including all qualifications, assumptions, exclusions, and risks. The 2022 Technical Report is intended to be read as a whole and sections should not be read or relied upon out of context.

Reasonable Prospects for Eventual Economic Extraction

Mensin Gold Bibiani holds the relevant mining lease, surface rights, major approvals and permits required for the planned and ongoing mining operations.

The Bibiani mineralization is part of a regional structure and is not the only deposit of its type in the region. The nature of the mineralisation style and setting are well understood and can support a declared Mineral Resource and further exploration potential.

Sampling methods, preparation, analyses, and security are performed to Industry Standards and subsequent data is fit for use in Mineral Resource and Mineral Reserve estimation. Appropriate QA/QC programs, to address precision and accuracy of information, are adhered to by the Company geologists and exploration teams.

The 2022 Technical Report provides an update of the previous Mineral Resource Estimate that was compiled from a geological model relevant to an underground operating strategy by previous owners. The Company has prepared a new geological model and updated Resource Estimate to satisfy the open pit operations. Snowden Optiro have remodelled the geological information to produce a revised and updated Resource Model and Resource Estimation for the Bibiani Main Pit and Satellites Pits (Walsh and Strauss).

The Bibiani Main Pit and Satellite Pits relevant to the 2022 Technical Report have been historically mined by both open pit and underground operations by several previous owners. Mineral Reserves are supported by a positive economic assessment assuming a US$1,850/oz Au price. The cut-off grade selected is appropriate for the Company objectives.

Recovery methods in the refurbished and upgraded process plant facility and gold recovery assumptions (92%) are supported by historical production and test work.

Mensin Gold Bibiani has received all necessary legal requirements and complies with environmental and social requirements. The Tailings Storage Facility was historically designed, recently refurbished, and continues to be managed under a current contract by Knight Piesold Ghana Limited.

Mensin Gold Bibiani has implemented a Resettlement Action Plan in alignment with the LoM Plan that will require a phased engineering and construction program to relocate the impacted community.

The discounted cash flow model for the proposed operation demonstrates that the Project is robust under the current techno-economic assumptions described in the 2022 Technical Report. The analysis supports the declared Mineral Reserve and supports the Company’s decision to progress the Project to full production.
