2023 Updated Company Reserves and Resources Statements
Hummingbird Resources plc (AIM: HUM) is pleased to provide updated Reserves and Resources Estimate Statements for the Company as at 31 December 2022.
Updated Group Reserves totalled 4.03 million ounces ("Moz") of gold and Group Resources totalled 6.95 Moz, a net decrease of 98 thousand ounces ("Koz") and 327 Koz respectively, on the Company's 2022 Reserves and Resources statement ("2022 statement" or "2022").
Kouroussa Gold Mine, Guinea
-- Reserves at the Kouroussa Gold Mine increased 28 Koz to 676 Koz at 4.13g/t (2022 statement: 647 Koz at 4.15g/t) and total Resources also increased 30 Koz to 1.23 Moz at 3.06g/t versus the previous statement (2022: 1.20 Moz at 3.02g/t).
-- Under the current mine plan, Kouroussa has a defined life of mine ("LOM") of at least six years. The mine holds significant untapped exploration upside with the Company planning on starting and executing exploration campaigns over the next 12 months with the goal of lifting the LOM to 10-plus years and increasing the Reserve profile to over 1.0 Moz.
Yanfolila Gold Mine, Mali
-- Following the curtailing of exploration activities in 2022, operational depletion, and re-interpreting geology from grade control drilling and improved in-pit mapping that increased geological confidence for mining plans, Yanfolila saw total Reserves decrease 126 Koz to 593 Koz at 2.64g/t (2022: 719 Koz at 2.85g/t) and Resources decreased 360 Koz to 1.71 Moz at 2.21g/t (2022: 2.07 Moz at 2.22g/t).
-- Yanfolila has a projected LOM of approximately six years based on its existing Reserve profile. Despite the reduction in Yanfolila's Reserves and Resources profile through 2022, the Company remains confident in its ability to maintain and extend Yanfolila's LOM. Exploration plans on greenfield and existing brownfield sites at Yanfolila are currently being implemented and expected to add to the Mineral Resource base in H2-2023 through to 2024.
Dugbe Gold Project, Liberia
-- Reserves remained as per last statements at 2.76 Moz at 1.30g/t and Resources at 4.01 Moz at 1.27g/t, of which the Company retains a 51% controlling interest.
Exploration activity
-- As noted in the Q2-2023 Operational and Trading Update, the Company is currently finalising its exploration plans at both Kouroussa and Yanfolila, with extension drilling re-commenced at Yanfolila's Gonka and Sanioumale West deposits . Further detail on the Group's exploration plans, including updates on the completed extension drilling, are expected to be provided later in the year.
-- The core focus of the exploration programmes will be to increase the respective Resource bases and, ultimately, enlarge the Reserves bases and LOM at both assets. In particular, the Company believes there remains material upside opportunity at Kouroussa, which is located within Guinea's gold prolific Siguiri Basin.

Dan Betts, CEO of Hummingbird Resources, commented:
"The last 18 months have been a period of significant operational progress for Hummingbird, with the construction and ramp-up of Kouroussa, which is expected to reach steady state production in Q4-2023, and the successful return to more consistent operational performance at Yanfolila. We are confident that our asset base has material LOM upside, with exploration plans being developed, in particular at Kouroussa, where we are targeting to increase Reserves to 1.0 Moz and a 10-plus year LOM."

Yanfolila Gold Mine, Mali Reserves and Resources key highlights:
Reserves at Yanfolila totalled 593 Koz at 2.64g/t, a decrease of 126 Koz, and Resources totalled 1.71 Moz at 2.21g/t, a decrease of 360 Koz. The decrease has been primarily driven by the significant geological reinterpretation of several deposits at Yanfolila utilising additional data captured through detailed grade control drilling and improved in-pit mapping, increasing geological confidence in Yanfolila's overall Resource base.
The Company remains confident in the ability to maintain and extend Yanfolila's LOM, with property wide exploration plans being implemented and expected to accelerate in H2-2023 and 2024.
The Yanfolila gold mine is located within the Yanfolila exploitation permit area. This area contains the following key deposits, that are included within the 2023 Company Reserves Statement:
-- Komana West ("KW")
-- Komana East ("KE")
-- Sanioumale West ("SW")
-- Sanioumale East ("SE")
-- Gonka ("GK")
-- Guirin West ("GW")
-- Komana East Underground ("KEUG")
-- Run-of-Mine Stockpiles ("ROM")
For the updated 2023 Yanfolila Resources Statement, the above deposits are included in addition to the below:
-- Komana West Underground ("KWUG")
-- Gonka Underground ("GKUG")
-- Sanioumale West Underground ("SWUG")
-- Sanioumale East Underground ("SEUG")
-- Kabaya South ("KS")
-- Badogo-Malikila ("BM") (non-code compliant)
-- Heap Leachable Stockpiles ("HLS")
KE and KEUG
The KE open pit deposit holds Reserves of 63 Koz (2.73g/t) and are included in the KE open pit Resources of 340 Koz (3.38g/t) respectively. The remaining Reserves for the KE open pit are located at the North and South ends of the pit that are on strike with the mineralised trend. The KE open pit Resources are reported within a US$1,800 per oz Au conceptual pit shell, resulting in a deeper pit and bringing previous potential Underground Resources into the new theoretical open pit, hence reducing the Underground Resource when compared with the last Resource statement of 2022.
The KEUG Reserves have been adjusted by depleting mineralisation that was recovered in 2022 in the KE open pit, standing at 265 Koz (4.02g/t). The Underground Reserves were estimated using a cut-off grade of 1.87g/t Au at an input price of US$1,500 per oz Au. Remaining open pit reserves of the current KE open pit are expected to be mined in FY-2024. Notably, there exists potential for a longer LOM at KEUG, well above the deposit's current Reserves and Resources profile which remains open at depth and to the north of the deposit. This provides confidence that Reserves can be increased, and Resources can be upgraded from Inferred Resources to the Measured and Indicated category through additional drilling campaigns at KEUG.
KEUG is currently being developed in H2-2023, with the expectations that once it enters production, further underground exploration drilling will take place to extend the LOM for that deposit.
KW
The KW open pit deposit holds Reserves and Resources of 38 Koz (2.54g/t) and 133 Koz (2.07g/t) respectively, accounting for mining depletions and geological reinterpretation since the previous statements. This deposit retains its potential at depth and along its southern strike for LOM extension with further exploration.
GK and GKUG
The GK open pit deposit currently holds Reserves and Resources of 32 Koz (3.01g/t) and 192 Koz (4.09g/t) respectively, accounting for mining depletions and the additional remodelling versus the 2022 statements. The GK deposit is being gradually mined, providing ore to be processed at the mill.
For GKUG, there are no current Reserves, and Resources have decreased, now standing at 80 Koz (3.31g/t) since the previous update. The primary cause for the changes in Resources, beyond mining depletion, is the larger pit shell using an input price of US$1,800 per ounce Au, increasing the proportion of the Resources that are within the open pit.
The Company does not expect GKUG to be part of the mine plans for several years, with additional technical studies and drilling currently being planned. However, the Company views GKUG as a future high-grade ore source for the processing plant, like KEUG, with the belief that further drilling is needed to enhance its potential.
SE and SEUG
The SE deposit had a slightly reduced Reserves and Resources profile of 102 Koz (2.57g/t), and 161 Koz (2.58g/t) respectively versus the 2022 statements. The increased reduction at SE was driven by optimisation of the mine design to reflect an updated Yanfolila exploitation permit area. Additionally, a Resource of 53 Koz (2.70g/t) was reported at SEUG. As with KEUG and GKUG, the Company anticipates further potential for expansion of Resources and Reserves with additional exploration drilling.
Mining at the SE open pit deposit commenced in Q2-2023, ahead of schedule, and will provide increased ore to be processed through H2-2023. Over the near term, the SE open pit will be a primary source of material for the processing plant and the Company is looking to increase operational tonnages to improve blending opportunities.
SW and SWUG
The SW open pit Reserves and Resources have decreased, now standing at 28 Koz (2.19g/t) and 107 Koz (1.60g/t) respectively, after accounting for mining depletion. The SW open pit remains a source of oxide ore material within the current LOM plan.
A Resource estimate of 26 Koz (2.25g/t) has been established at SWUG. Like the Company's other underground deposits, it expects there to be further potential for open pit mineralisation through additional exploration drilling.
GW
A Maiden Reserve of 7 Koz (2.13g/t) has been reported for GW. The GW deposit is located near to the processing plant and could provide a future source of oxide material, with further exploration upside potential.
KS & BM
KS Resources classified under SAMREC protocols were maintained at 85 Koz (1.31g/t). Additionally, the deposit includes non-code compliant Resources of 46.0 Koz (1.50g/t). BM holds a total non-code compliant Resources of 61 Koz (0.81g/t).
HLS
HLS Resources have seen a slight reduction to 28 Koz (0.57g/t). Currently, HLS is not included in the Yanfolila LOM plans. However, the Company believes through additional studies, HLS Resources could be converted into Reserves, making HLS a potentially viable ore source for processing in the upcoming years.
ROM (stockpiles)
Presently, the ROM contains Reserves amounting to 58 Koz (1.08g/t), a rise of 31 Koz compared to the figures stated in previous statements. This increase is due to improved geological confidence in the ability to profitably mine the existing ROM stockpiles in the future.
Kouroussa Gold Mine, Guinea Reserves and Resources key highlights:
Kouroussa Reserves increased 28 Koz to 676 Koz at 4.11g/t and Resources increased 30 Koz to 1.23 Moz at 3.06g/t from previous statements.
The project holds significant exploration upside both on site and in the surrounding region. The Company remains confident in reaching its target of a 10+ year LOM and a 1.0 Moz Reserve at Kouroussa.
The current Kouroussa Reserves stated are for the Koekoe and Kinkine open pits only. Resources are included for other deposits and potential underground mineralisation below the Koekoe and Kinkine open pits for the following;
-- Koekoe ("KK")
-- Kinkine ("KI")
-- Bag Farm-Junction ("BFJ")
-- X-Vein ("XV")
-- Koekoe underground ("KKUG")
-- Kinkine underground ("KIUG")
KK and KKUG
Reserves at KK increased 28 Koz, to total 574 Koz (4.63g/t), while Resources increased 59 Koz, to total 763 Koz (3.90g/t) from the previous statements. At KKUG, Resources decreased to 133 Koz (2.11g/t) since the last statement. The principal factors driving these changes we re the inclusion of additional assay results not included in the previous 2022 statement, as well as the remodelling of the deposit which incorporated the shallower regions of the KKUG deposit into the KK open pit model .
KI and KIUG
The Reserve at KI remained unchanged from the previous statements, totalling 101 Koz (2.56g/t), while Resources also remained steady at 137 Koz (2.18g/t). Resources at KIUG have remained unchanged from the previous statements, totalling 24 Koz (1.75g/t). The Company believes that there is potential to grow the underground Resources at KIUG through additional exploration.
Bag Farm-Junction (BFJ) and X-Vein (XV)
The Resources for BFJ and XV have remained unchanged from the previous statements, at 89 Koz (1.59g/t) and 83 Koz (7.33g/t) respectively. Both deposits possess the potential to be develop into future mining deposits, pending more detailed exploration.
Dugbe Gold Project, Liberia Reserves and Resources key highlights:
The Reserves and Resources for Dugbe have remained unchanged since the previous statements, standing at 2.76 Moz and 4.01 Moz respectively. Hummingbird retains a 51% controlling interest in the project.
A strategic review of the Dugbe Project remains ongoing with the Company's joint venture partner, Pasofino Gold Limited ("Pasofino").

Notes to Editors:
Hummingbird Resources plc (AIM: HUM) is a leading multi-asset, multi-jurisdiction gold producing Company, member of the World Gold Council and founding member of Single Mine Origin (www.singlemineorigin.com). The Company currently has two core gold projects, the operational Yanfolila Gold Mine in Mali, and the Kouroussa Gold Mine in Guinea, which will more than double current gold production once at commercial production. Further, the Company has a controlling interest in the Dugbe Gold Project in Liberia that is being developed by joint venture partners, Pasofino Gold Limited. The final feasibility results on Dugbe showcase 2.76Moz in Reserves and strong economics such as a 3.5-year capex payback period once in production, and a 14-year life of mine at a low AISC profile. Our vision is to continue to grow our asset base, producing profitable ounces, while central to all we do being our Environmental, Social & Governance ("ESG") policies and practices.
