2022 Updated Company Reserves and Resources Statements

4.13 million ounces of Company Reserves

7.28 million ounces of Company Resources

Hummingbird Resources plc (AIM: HUM) is pleased to provide updated Company Reserves and Resources Estimate statements for each of its three gold assets which include: Yanfolila in Mali; Kouroussa in Guinea, including a maiden Ore Reserve at the Kinkine deposit and higher-grade Ore Reserves at the Koekoe deposit; and maiden Reserves for Dugbe in Liberia, as announced on 13 June 2022.

Hummingbird's updated Company Reserves have increased materially to 4.13 million ounces ("Moz") of gold ("Au") from 1.12Moz, as reported in November 2021 and Resources have increased 8% to 7.28Moz of Au since previous statements, as summarised in the table and key highlights below for each asset.

2022 Company Reserves and Resources Summary Table and Highlights:

COMPANY RESERVES		Reserves Summary			Net change from previous updates
Asset:		kt	g/t	koz	koz	% Change
Yanfolila, Mali (net of depletions)		7,853	2.85	719	13	2%
Kouroussa, Guinea		4,856	4.15	647	238	58%
Dugbe, Liberia		66,000	1.30	2,760	2,760	-
Total Company Reserves		78,709	1.63	4,126	3,011	270%
COMPANY RESOURCES		Resources Summary			Net change from previous updates
Asset:		kt	g/t	koz	koz	% Change
Yanfolila, Mali (net of depletions)		28,946	2.22	2,065	100	5%
Kouroussa, Guinea		12,365	3.02	1,200	22	2%
Dugbe, Liberia		98,100	1.27	4,013	447	11%
Total Company Resources		139,411	1.62	7,279	569	8%

All Company Resources and Reserves are shown on a 100% basis. Hummingbird will retain a controlling interest in Dugbe of 51%.

§ Yanfolila, Mali : Reserves and Resources total 719 thousand ounces ("koz"), an increase of 13koz (+2%) at 2.85 grams a tonne ("g/t"), and Resources of 2.07Moz at 2.22 g/t, an increase of 100koz (+5%) net of depletion from mining since the previous statements respectively. Notably underground Reserves at Komana East ("KEUG") increased by 75koz (+37%), to total 278koz at 3.94 g/t

o  With Yanfolila's current Reserves and Resources profile, the Company is confident of a minimum seven-year life of mine ("LOM") based on a c.100koz annual production profile, with potential to maintain and extend Yanfolila's LOM with further drilling campaigns, in particular at the underground deposits which are of higher grade

§ Kouroussa, Guinea: Reserves and Resources total 647koz at 4.15 g/t, an increase of 238koz (+58%) and 1.20Moz at 3.02 g/t, an increase of 22koz (+2%) since the previous statements respectively. Notably, key deposit Koekoe's Reserves increased by 137koz (+33%) since last reported to total 546koz and at a higher-grade profile of 4.69 g/t (+7% versus the last statement at 4.38 g/t). Further, a maiden Reserve was established at the other key Kouroussa deposit, Kinkine, of 101koz at 2.56 g/t

o  Kouroussa's Reserves profile provides the Company with increasing confidence of a robust and high-grade geology base as we move towards first gold pour by the end of Q2 2023. Further, given the significant exploration upside potential at Kouroussa, the Company is confident of extending the Reserves and LOM at this asset with further exploration, which is currently being evaluated

§ Dugbe, Liberia: A maiden Reserve of 2.76Moz and Resources of 4.0Moz as recently announced by our joint venture partners at Dugbe, Pasofino Gold Ltd ("Pasofino") on 13 June 2022, of which Hummingbird will retain a controlling interest in Dugbe of 51%

A core value-accretive strategy for Hummingbird has been to increase the Company's Reserves asset base through extensive drilling programmes.  Today's announcement highlights the success of these campaigns, with material Company Reserves and Resources increases which provide further Life of Mine ("LOM") extensions to our asset base.  

Dan Betts, CEO of Hummingbird Resources, commented:

"Two years ago, we set a key Company target to increase our overall Company Reserves profile to provide meaningful LOM extensions at our assets. In November 2021, we established maiden Reserves at Kouroussa in Guinea and added further Reserves at Yanfolila. In this update we have materially extended Kouroussa's Reserves profile to 647koz at 4.15g/t and added Reserves net of depletions at Yanfolila to total 719koz, including extending the underground Reserves profile of Yanfolila to 278koz at 3.94 g/t. Further, at Dugbe via our earn in partners Pasofino, final feasibility study results were recently announced, establishing a material maiden Reserves profile for the Project of 2.76Moz in which we will retain a controlling 51% interest.

As we rapidly move towards our other key strategic goal of being a multi-asset, multi-jurisdiction gold producer, with Kouroussa advancing towards first gold pour by the end of Q2 2023, we are cognisant to maintain and improve our overall Company Reserves profile. With today's results, and a large body of work now complete by our geology teams, the next steps include the further analysis of our extensive geological base and associated mine plans, as well as the next phase of our exploration campaigns in Mali and Guinea."

Anthony Köcken , COO of Hummingbird Resources, commented:

" Exploration and Resources and Reserves growth are key to achieving Hummingbird's strategic growth plans and creating value for all of our stakeholders. We have increased Reserves net of mining depletions at Yanfolila, in particular extending the asset's underground profile; materially increased the Reserves profile at Kouroussa; and maiden Reserves have been established at Dugbe. Further growth to the Company's mineral inventory is under review, with several high-potential targets being evaluated, including further extending underground targets at Yanfolila and several other deposits at Kouroussa."

Company Resources are shown on a 100% basis. Hummingbird will retain a controlling interest in Dugbe of 51%. Yanfolila and Kouroussa Resources effective date is 31.12.2021.  Dugbe Resources effective date as prepared by Pasofino is 17.11.2021. Footnotes: Due to the length of the footnotes to the Resources summary table, they are provided at the end of this document.

Yanfolila, Mali Reserves and Resources key highlights:

As per the highlights above, Reserves and Resources total 719koz at 2.85g/t, an increase of 13koz (+2%), and Resources of 2.07Moz at 2.22 g/t, an increase of 100koz (+5%) net of depletion from mining since the previous statements.

Notably underground Reserves at KEUG increased by 75koz (+37%), to total 278koz at 3.94 g/t and Gonka underground Resources totalled 225koz at high grades of 4.16 g/t, being an addition of 68koz (+43%) since the last statement.  With Yanfolila's current Reserves and Resources profile the Company is confident of a minimum seven-year LOM based on a c.100koz annual production profile, with potential to maintain and extend Yanfolila's LOM with further drilling campaigns, in particular at the underground deposits which are of a higher grade to the open pit operations.  

The Yanfolila gold mine is located within the Yanfolila exploitation permit area. The permit area contains the following six key deposits, that are included within the 2022 Company Reserves Statement, including run of mine ("ROM") stockpiles:

§ Komana East ("KE")

§ Komana East Underground ("KEUG")

§ Komana West ("KW")

§ Gonka ("GK")

§ Sanioumale West ("SW")

§ Sanioumale East ("SE")

For the updated 2022 Yanfolila Resources Statement, the above deposits are included in addition to the below:

§ Gonka Underground ("GKUG")

§ Guirin West ("GW")

§ Kabaya South ("KS")

§ Badogo-Malikila ("BM")

§ Heap leach Stockpiles ("HLS")

KE and KEUG

The KE open pit deposit has current Reserves and Resources of 106koz at 2.99 g/t and 115koz at 3.20 g/t respectively, net of mining depletions since last statements. It continues to be mined and is a primary source of higher-grade ore, in particular for the remainder of 2022 and into 1H2023 to the processing plant.  The open pit is scheduled to be fully mined during 1H2023 with other open pits providing future ore to the processing plant when KE is depleted as detailed below.

A key focus of our 2020 and 2021 drilling campaigns at Yanfolila has been to increase the Reserves at KEUG to provide high-grade future LOM ore at the asset.  This has been achieved with KEUG Reserves and Resources increasing 75koz (+37%) to total 278koz at 3.94 g/t, and 128koz (+30%) to total 555koz at 3.94 g/t since last statements respectively. 

There remains mineralisation extension potential at depth and to the north of the deposit providing the Company with confidence that both Reserves and Resources can continue to be extended with further drilling campaigns. KEUG is expected be a key source of base load c.40-50koz per annum high-grade ore for the processing plant in future years given the now material level of current Reserves. With the 2022 KEUG Reserves now complete, we are finalising our detailed analysis of the KEUG deposit in terms of economics, mining and when to incorporate it into our future mine plans at Yanfolila.  We will provide more details of these plans once finalised. 

KW

The KW open deposit has current Reserves and Resources of 75koz at 2.62 g/t and 353koz at 1.84 g/t respectively, net of mining depletions since last statements. It is a deposit which continues to be actively mined, being a pit that has four open pit phases. The deposit remains open at depth and along strike to the south, which our geology team are assessing the potential for future extension drilling campaigns at the deposit.

GK and GKUG

GK open pit deposit has current Reserves and Resources of 66koz at 3.15 g/t and 67koz at 3.45 g/t respectively, net of mining depletions since last statements. The deposit is currently gradually being mined, providing additional ore feed to the processing plant.

GKUG does not yet have a Reserve, however Resources increased by 68koz (+43%) to total 225koz at 4.16 g/t since last statements. With further drilling, the Company believes GKUG will be a future high-grade source of ore to the processing plant, like the KEUG. GKUG is not expected to be in our future mine plans for several years, with further technical studies and drilling expected to be undertaken in 2023.

SE

SE open pit deposit has a current Reserves and Resources of 112koz at 2.53 g/t, adding 12koz (+10%) and 236koz at 2.49 g/t, adding 32koz (+16%) since last statements respectively. The 2021 drilling campaign focussed on infill drilling for upgrading Mineral Resources and resulted in the conversion of 50koz Inferred to Indicated Mineral Resources, of which a larger proportion has the potential to be included in future Reserves dependent on economics. The secondary focus of the drilling campaign was on the 1.2-kilometre ("km") strike zone where the SE deposit lies in what is known as the Sankarani Shear Zone which also hosts the KE and GK deposits. As it currently stands the SE pit is made up of three pits, which are currently being prepared for mining. Our geology team is evaluating the SE geology databases and the potential for any of the three open pits to be connected into a larger pit formation, plus the potential for future exploration campaigns at that deposit.  

SW

SW open pit deposit has current Reserves and Resources of 55koz at 1.86 g/t, being a net increase of 5koz (+10%) and 191koz at 1.72 g/t, being a net increase of 27koz (+16%) since last statements respectively, net of mining depletions. The focus of the 2021 drilling campaign was infill drilling to increase confidence of the geology base, resulting in an upgrade of 29koz from Inferred to Indicated Mineral Resources. SW is currently being mined and is a source of oxide ore material within the current LOM plan.

HLS

The Company decided in 2021 to evaluate the potential for Heap Leach ("HL") at Yanfolila given the availability of lower-grade and more marginal resource stockpiles. The Company commissioned HL specialist consultants JUMPS and CSA Global Pty Ltd to conduct feasibility studies for HL potential at Yanfolila, which culminated in adding HLS Resources of 31koz at 0.60 g/t into the 2022 Company updated Resources statement.  At this stage HL is not in Reserves and is not in our current Yanfolila LOM plans.  However, the Company believes with further studies, Reserves for HL can be added to then allow HL to be a viable source of ore feed to be processed in the coming years.  

Kouroussa, Guinea Reserves and Resources key highlights:

As per the highlights above, Kouroussa Reserves and Resources total 647koz at 4.15 g/t, an increase of 238koz (+58%) and 1.20Moz at 3.02 g/t, an increase of 22koz (+2%) since the previous statements respectively.

The current Kouroussa Reserves are in the following deposits:

§ Koekoe ("KK")

§ Kinkine ("KI")

For the updated 2022 Kouroussa Resources Statement, the above deposits are included in addition to the below:

§ Bag Farm-Junction ("BFJ")

§ X-Vein ("XV")

§ Koekoe underground ("KKUG")

§ Kinkine underground ("KIUG")

KK and KKUG

In our November 2021 Reserves statement, a maiden Kouroussa Reserve at KK was established with 409koz at 4.38 g/t. With a c.24,000 m infill drilling campaign completed in 2021 at Kouroussa, KK Reserves increased by 137koz (+33%) to now total 546koz at a higher-grade profile of 4.69 g/t (+7% versus the last statement at 4.38 g/t). Further of note, KKUG Resources increased materially by 142koz to total 164koz at 2.30 g/t since the last statement, providing confidence of underground mining potential at Kouroussa.

KI and KIUG

As noted in the highlights, a maiden Reserve at the KI deposit was established of 101koz at 2.56 g/t being another key notable success of this year's Reserves statement for Kouroussa. 

The KI deposit is situated near the KK deposit and the processing plant, which is currently under construction. With further exploration, the Company is confident that the KI and KIUG deposits Reserves and Resources base can grow.  Although Resources at KIUG remain relatively low at 24koz, additional exploration has the potential to increases the underground Resources.  

The Company believes it has only just started its journey to tap the full exploration potential of the Kouroussa asset in the heavily gold endowed Siguiri Basin region. Underground extensions at both the KK and KI deposits exist with mineralisation remaining open at depth from multiple drill intercepts during the 2021 drilling campaign, in particular at the KK deposit. Further, other Kouroussa deposits, such as X-Vein and Bag Farm-Junction show potential to be future mining deposits yet to be fully explored. Future exploration plans are being formulated for Kouroussa, given the success of last year's infill drilling campaign, with the Company confident of reaching its strategic goal of having 10 years in Reserves mine life at this asset.

Dugbe, Liberia Reserves and Resources key highlights:

On 13 June 2022, Pasofino released  the results of the Dugbe Gold Project Feasibility Study ("FS"). The release highlighted a material maiden Reserve of 2.76Moz and Resources of 4.01Moz being an increase of 447koz since Pasofino's last Mineral Resources Estimate ("MRE") update, of which Hummingbird will retain a 51% controlling interest in the project.

As detailed in the FS release, Dugbe is a large-scale gold asset with a 14-year LOM, low All In Sustaining Cost ("AISC") profile of US$1,005/oz, with material exploration upside potential given only six of the probable 100 targets have been explored over the 2,559km² exploration license area.  

With the FS complete, the Company is working with Pasofino to conduct a strategic review of our options to best realise the maximum value of Dugbe for all stakeholders.

"Au"	the chemical symbol on the periodic table for the precious metal, gold.
"Cut-off grade"	the lowest or highest assay value that is included in a resource estimate.
"Deposit"	mineralisation which has been outlined on surface and via underground work or drilling sufficient for a Mineral Resource Estimate to be calculated with tonnage and grade but where there has been no ore production.
"Indicated resource"	that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade, and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings, and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed.
"Inferred Resource"	that part of a Mineral Resource for which tonnage, grade and mineral content can be estimated from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings, and drill holes which is of uncertain quality and reliability.
"JORC"	the Joint Ore Reserves Committee of the Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Mineral Council of Australia.
"JORC 2012"	the 2012 edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves.
"Measured Resource"	that part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade, and mineral content can be estimated with a high level of confidence. It is based on detailed and reliable exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings, and drill holes. The locations are spaced closely enough to confirm geological and grade continuity.
"Mineral Resource"	mineral of potential value but not necessarily proven as a reserve.
"Ore"	mineral of proven economic value.
"Ore Reserve"	the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined. Appropriate assessments and studies have been carried out and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social, and governmental factors. These assessments demonstrate at the time of reporting that extraction could reasonably be justified. Ore Reserves are sub-divided in order of increasing confidence into Probable Ore Reserves and Proved Ore Reserves. A Probable Ore Reserve has a lower level of confidence than a Proved Ore Reserve but is of sufficient quality to serve as the basis for a decision on the development of the deposit.
"Probable Reserve"	The economically mineable part of an Indicated, and in some circumstances, a Measured Mineral Resource.
