Hummingbird Resources provides Kouroussa Guinea update

Published by
Global Mining Review,


Hummingbird Resources plc has provided an update on the company's mine development progress and results from further assays of the 2021 resources and reserves infill drilling programme at the Kouroussa Gold Mine in Guinea.

Kouroussa update

The development and construction of Kouroussa continues to advance rapidly and remains on track to achieve the scheduled first gold pour by the end of 2Q23. The construction update is as follows:

  • Civil and construction works:
    • Civil works have begun, and earthworks are nearing completion at the processing plant with mine camp site areas to then allow for cement foundation works to begin.
    • Foundation concrete and steel reinforcement work is taking place for the CIL tanks installation.
    • Mine camp for construction personnel is now operational, allowing the company to have more construction personnel on site versus housed in the local areas, with over 350 construction, administrative and security personnel in place for the overall construction process.
  • Processing plant:
    • Fabrication of the CIL tanks have commenced on-site and are rapidly advancing towards completion.
    • Structural, mechanical, and piping works will begin following the completion of foundation works at the process plant area.
  • Long lead items, contracts, and community engagement:
    • Further long lead items have been purchased, including apron feeders, jaw crusher, SAG mill, cyclone cluster and agitators.
    • Construction equipment, tooling, machinery, personnel, and consumables continue to arrive on-site and are in position for the next phase of the overall build process.
    • Power plant and mining contractor contracts are in the final stages of negotiation and are expected to be awarded soon.
    • Detailed community engagement is taking place with our on-site health, safety, environmental and community (HSEC) teams.

Kouroussa drilling highlights:

Hummingbird has received assay results on a further 86 reverse circulation (RC) and 12 diamond holes on the high-grade Koekoe (KK) deposit, delivering approximately 9900 m of the company's c.24 000m infill 2021 drilling programme. The focus of this infill drilling programme has been to convert current in-pit Inferred material to Indicated and build upon the already extensive historical drilling to expand Kouroussa’s life of mine and overall Reserves base.

The company is awaiting the final c.3600 m of assays, which are expected to be received soon and will conclude the 2021 Kouroussa drilling results to be received.

  • Notable drill results from the KK deposit include:
    • KRC1953: 3 m at 18.63 g/t from 27 m.
    • KRC2003: 7 m at 2.98 g/t from 36 m.
    • KRC2036: 11 m at 5.62 g/t from 64 m.
    • KRC2041: 3 m at 34.84 g/t from 51 m.
    • KRC2042: 1 m at 47.60 g/t from 152 m.
      • Hole KRC2042 ended with mineralisation ongoing.
    • KRC2044: 9 m at 4.55 g/t from 34 m.
    • KRCD1886: 2 m at 9.65 g/t from 120 m.
    • KRCD1891: 8.6 m at 6.31 g/t from 107.6 m.
    • KRCD1896: 7 m at 9.83 g/t from 101 m.
    • KRCD1898: 12.6 m at 5.11 g/t from 66.45 m.

These and previous results continue to show the significant gold endowment at Kouroussa, with multiple high-grade zones that remain open.

These assays, alongside additional results from the Kouroussa and Yanfolila drilling programmes will feed into the updated company 2022 resources and reserves statement that is expected to be released in 2Q22.

Dan Betts, CEO of Hummingbird Resources, commented: “We are rapidly advancing into the next phase of the Kouroussa build process with civil works now underway. We remain focused on delivering Kouroussa on schedule and on budget for a first gold pour by the end of 2Q23, which will then more than double our current production profile.

“Our 2021 Kouroussa drilling programme continues to deliver results that highlight the significant gold endowment we have at Kouroussa. Our geology team has also identified thicker mineralisation zones and shallower dipping westerly zones than originally believed, which is a positive for future mining at Kouroussa. These results continue to be analysed and incorporated into our updated company resources and reserves statement, which is expected to be released at the end of 2Q22.”

Anthony Köcken, COO of Hummingbird Resources, added: “Our Kouroussa construction team is working well in advancing the project towards the first gold pour. We are now in the civil work construction phase, which involves a new level of technical expertise that our teams are now bringing into the overall process. The awarding of power and mining contractor contracts is nearing finalisation, which will also be a key milestone for Kouroussa, allowing key infrastructure and mining processes to begin.”
