Hummingbird Resources plc provided an update on the company's mine development progress and results from further assays of the 2021 Resources and Reserves infill drilling programme, including a notable hole of 24 meters ("m") at 5.33 grams per tonne ("g/t") amongst others, at the Kouroussa Gold Mine in Guinea. Hummingbird has received further assay results on 30 Reverse Circulation ("RC") and three diamond holes on the high-grade Koekoe ("KK") deposit, delivering approximately 3,200 meters out of the Company's c.24,000m infill drilling programme for 2021. To date, the Company has received c.10,050m of assays from the 2021 programme, with more expected in First Quarter 2022.

Notable drill results from the KK deposit include: 24m at 5.33 g/t from 28m (KRC1873), 3m at 16.06 g/t from 118m (KRC1890), 3m at 11.64 g/t from 55m (KRC1803), 4m at 10.31 g/t from 89m (KRC1858), 4m at 9.09 g/t from 49m (KRC1858), 4m at 9.76 g/t from 146m (KRCD1878), 2m at 8.48 g/t from 25m (KRC1824), 8m at 7.77 g/t from 95m (KRC1864), 4m at 6.17 g/t from 99m (KRC1890), 4m at 4.28 g/t from 35m (KRC1854), 8m at 3.22 g/t from 56m (KRC1874). The Company continues to receive ongoing high-grade drill intercepts, coupled with multiple thick mineralisation zones, from infill drilling campaign completed in 2021. These updated results continue to provide increasing confidence and geological knowledge of the high-grade nature of Kouroussa's key deposit KK.

The KK deposit has a current maiden Reserve of 408,900 ounces ("oz") at 4.38 g/t, with upside potential once all the 2021 c.24,000 m infill drilling data is analysed, and which will feed into updated company 2022 Resources and Reserves statements that are scheduled for release in Second Quarter 2022.
