NEWS RELEASE SEPTEMBER 20, 2021

HANNAN CHANNEL SAMPLES 1.6m @ 5.3% COPPER AND 83 g/t SILVER

AND CONFIRMS REDUCED SHALE HOST AT TABALOSOS EAST, PERU

Vancouver, Canada – Hannan Metals Limited (“Hannan” or the “Company”) (TSXV: HAN) (OTCPK:

HANNF) reports on exploration program results from the Tabalosos East prospect within the San Martin JOGMEC

JV sediment-hosted copper-silver project in Peru (Figures 1 and 2).

Highlights:

 Surface channel sampling from ou tcrops at Tabalosos East, taken over a 500-metre strike, returned

s i g n i f i c a n t r e s u l t s f r o m t h r e e n e w o u t c r o p s . T h e z o n e i s l o c a t ed 1.9 kilometres north of previously

reported mineralization and is interpreted to be hosted in the same min eralized horizon. Better assays

included (Figures 1 and 2):

o 2.8 metres (“m”) @ 3.0% copper (“Cu”) and 48 g/t silver (“Ag”) (partially sampled)

 Including 1.6m @ 5.3% Cu and 83 g/t Ag

o 2.0m @ 1.1 % Cu and 11 g/t Ag

o 0.2m @ 2.2 % Cu and 27 g/t Ag (partially sampled)

 Separately, 1.2 kilometres east of the new outcrops, mapping ov er significant distances of mineralized

outcrops in trenches, exposed be neath soil anomalies, clearly d emonstrates that copper is hosted by a

fine grained, organic-rich reduced shale within a bleached package of shaly siltstones:

o A 10m wide altered and bleached zone with anomalous copper has been mapped and inferred

over 650m of strike with geochemical assays from 380m of strike including 1.2m @ 0.52% Cu

and 6 g/t Ag and 3.5m @ 0.73% Cu and 9 g/t Ag including 0.2 m @ 1.1% Cu and 13 g/t Ag;

o This is considered critical new geological information, as it is the first time that detailed mapping,

over the larger scale, has defined a mappable, consistent, and well-defined fine-grained, reduced

organic shale, previously only mapped between sporadic boulders and poorly exposed outcrops;

o This provides further evidence that the mineralization at San Martin and is of the reduced facies

sediment hosted copper-silver “Kupferschiefer” style;

 All mineralization described above is located at Tabalosos East where the company is currently preparing

an Environmental Impact Statement (Declaración de Impacto Ambie ntal, or "DIA") study. The DIA,

previously reported here, will allow low impact mineral exp loration that includes diamon d drilling of up

to 40 platforms in a 9 x 3 kilometre area. Subject to permitti ng, drilling is anticipated to take place in

Q2 2022.

Michael Hudson, CEO, states, "Further high-grade surface channel samples with a highlight r esult of 1.6m @

5.3% Cu and 83 g/t Ag from outcrop mineralization attest to the thickness of high-grade copper and silver

mineralization that we continue to uncover at San Martin over s uch large scales (Figure 2). However, equally

important is the first detailed work to emerge from the project that demonstrates a consistent and mappable

organic and reduced shale that hosts mineralization, that furth er geologically supports the reduced facies

sediment-hosted style. This geol ogical style globally forms the largest and most consistent sediment-hosted

copper systems, and includes the vast Kupferschiefer deposit in Eastern Europe and deposits of the African

Copper Belt in sub-Saharan Africa, two of the largest copper di stricts on earth. We hav e multiple geological

2

teams unravelling the opportunit y while permitting and social t eams continue to work together with all

stakeholders on the DIA, to permit diamond drilling.”

Detailed mapping of outcrops with correlating stratigraphic columns demonstrates that copper mineralization in

the new zone mentioned above is hosted by an organic rich shale facies within an approximately 10m thick

bleached/altered and copper anomalous package of shaly siltston es. This sequence represents a different

depositional environment of lower energy that has facilitated the deposition of a consistent organic-rich, reduced

shale facies. The impact on the exploration model is fundamental, as it supports the assumption of a widespread

reduced facies across the Huallaga basin.

Five geologists and associated f ield assistants, two social con sultants plus two local social support, two

archaeologists and other external environmental consultants related to the DIA program have been engaged at

Tabalosos East. In other work, a total of 2,329 soil samples have now been collected within the DIA area, and

22 pits and trenches have been dug below the soil samples. Additionally, a total of 90% of the 64,500 hectares

or 2,782-line kms of LiDAR have b een acquired at the San Martin JOGMEC JV sediment-hosted copper-silver

project with the survey to be completed in the coming weeks when weather conditions allow.

Technical Background

All samples were collected by Ha nnan geologists. Rock and sedim ent samples were transported to ALS in Lima via third

party services using traceable parcels. At the laboratory rock samples were prepared and analyzed by standard methods.

The sample preparation involved crushing 70% to less than 2mm, riffle split off 250g, pulverize split to better than 85%

passing 75 microns. The crushers and pulverizes were cleaned wi th barren material after every sample. Samples were

analyzed by method ME-MS61, a four acid digest preformed on 0.2 5g of the sample to quantitatively dissolve most

geological materials. Analysis is via ICP-MS.

Channel samples are considered representative of the in-situ mineralization samples and sample widths quoted approximate

the true width of mineralization, while grab samples are select ive by nature and are unlikely to represent average grades

on the property.

About the San Martin JOGMEC JV Project (Copper-Silver, Peru, 88 mining concessions for 660 sq km)

On November 30, 2020 Hannan announced that it had signed a binding letter agreement for a significant Option and Joint

Venture Agreement (the “Agreement”) with JOGMEC. Under the Agreement, JOGMEC has the option to earn up to a 75%

beneficial interest in the San Martin Project by spending up to US$35,000,000 to deliver to the joint venture (“JV”) a

feasibility study.

The Agreement grants JOGMEC the option to earn an initial 51% o wnership interest by funding US$8,000,000 in project

expenditures at San Martin over a four-year period, subject to acceleration at JOGMEC’s discretion.

JOGMEC, at its election, can then earn:

 an additional 16% interest for a total 67% ownership interest by achieving either a prefeasibility study or funding

a further US$12,000,000 in project expenditures in amounts of a t least US$1,000,000 per annum (for a

US$20,000,000 total expenditure); and,

 subject to owning a 67% interest, a further 8% interest for a t otal 75% ownership interest by achieving either a

feasibility study or funding a further US$15,000,000 in project expenditures in amounts of at least US$1,000,000

per annum (for a US$35,000,000 total expenditure).

Should JOGMEC not proceed to a prefeasibility study or spend US $20,000,000 in total, Hannan shall have the right to

purchase from JOGMEC for the sum of US$1, a two percent (2%) Pa rticipating Interest, whereby Hannan’s Participating

Interest will be increased to fifty-one percent (51%) and JOGME C’s Participating Interest will be reduced to forty-nine

percent (49%).

At the completion of a feasibility study, JOGMEC has the right to either:

 p u r c h a s e u p t o a n a d d i t i o n a l t e n p e r c e n t ( 1 0 % ) P a r t i c i p a t i n g I nterest from Hannan Metals (for a total 85%

maximum capped Participating Interest) at fair value as determined in accordance with internationally recognized

professional standards by an agreed upon independent third-party valuator; or

3

 receive up to an additional ten percent (10%) Participating Interest from Hannan (for a total 85% maximum capped

Participating Interest) in consideration of JOGMEC’s agreement to fund development of the project, by loan carrying

Hannan until the San Martin Project generates positive cash flow.

After US$35,000,000 has been spent by JOGMEC and before a feasibility study has been achieved, both parties will fund

expenditures pro rata or dilute via a standard industry dilutio n formula. If the Participating Interest in the Joint Venture

of any party is diluted to less than 5% then that party’s Parti cipating Interest will be automatically converted to a 2.0%

net smelter royalty (“NSR”), and the other party may at any time purchase 1.0% of the 2.0% NSR for a cash payment of

US$1,000,000. Hannan will manage exploration at least until JOG MEC earns a 51% interest, after which the majority

participant interest holder will be entitled to act as the operator of the joint venture. Initial exploration activities will focus

on the collection of the geological, geophysical, and geochemical datasets in the JV project areas.

Sediment-hosted stratiform copper-silver deposits are among the two most important copper sources in the world, the

other being copper porphyries. They are also a major producer of silver. According to the World Silver Survey 2020

KGHM Polska Miedz’s (“KGHM”) three copper-silver sediment-hosted mines in Poland are the leading silver producer in the

world with 40.2Moz produced in 2019. This is almost twice the p roduction of the second largest producing mine. The

Polish mines are also the sixth l argest global copper miner and in 2018, KGHM produced 30.3 Mt of ore at a grade of

1.49% copper and 48.6 g/t silver from a mineralized zone that averages 0.4m to 5.5m thickness.
