Hummingbird Resources plc to provide an updated JORC-compliant Company Reserve statement (?reserve statement?), which includes a maiden reserve for the Kouroussa mine in Guinea. Hummingbird's updated reserves total 1.12 million ounces (?oz?) of gold (?Au?), a 438,600 oz increase to the previous Company reserve statement in October 2019 of 672,000 oz. Updated Company reserves as of 30 June 2021 total 1.12 million oz at 3.03 grams per tonne (?g/t?), comprising: Yanfolila mine in Mali: 705,800 oz at 2.57 g/t, being a net increase of 29,700 oz, including depleted reserves from mining since the previous Company reserve statement in October 2019. The Yanfolila mine reserves include both open pit reserves on six deposits totaling 503,600 oz at 2.30 g/t (including stockpiles) and a maiden underground reserve at Komana east (?KEUG?) of 202,200 oz at 3.64 g/t. Kouroussa mine in Guinea: 408,900 oz at 4.38 g/t establishing a maiden reserve at that asset. These reported reserves for both Yanfolila and Kouroussa have upside potential as they do not include the 2021 drilling campaign of approximately 68,000 metres (?m?) (approximately 44,000 m at Yanfolila and approximately 24,000 m at Kouroussa). The results of this year's drilling campaign will be included in the 2022 updated Company Resource and Reserve statements, scheduled to be released in second quarter of 2022. Yanfolila Mine, Mali - The majority of the JORC compliant Yanfolila reserves increase has come from two key future mining deposits, including the new underground reserves at KEUG and the maiden open pit reserves at the Sanioumale East deposit (?SE?). Identification of reserves at both deposits are a result of the Company's investment and focus on exploration in 2020 with a total of approximately 21,000 m being drilled, with potential for further increases in reserves with a total of approximately 41,000 m being drilled in 2021 at Yanfolila, but which is not included in this reserve statement, as noted above. The new reserves at Yanfolila from these deposits are split as follows: KEUG: 202,200 oz at 3.64 g/t; and SE: 100,300 oz at 2.64 g/t. Kouroussa Mine, Guinea - Kouroussa's maiden open pit reserve of 408,900 oz at 4.38 g/t, was from the main and large deposit called Koekoe (?KK?). The reserve is supported by the JORC compliant resource statement as completed by independent mining consultancy company, Mining Plus, in May 2020. As stated above, there is upside potential to the Kouroussa maiden reserve number in the 2022 Company Resource and Reserve statements with the inclusion of the 2021 infill drilling campaign of approximately 24,000 m. Further, the Company expects the large of the three other key deposits at Kouroussa, called Kinkine, to have a maiden reserve in the 2022 Company Resource and Reserve statements.
