NEWS RELEASE March 27, 2018

HANNAN PLANS 20,000 METRE DRILL PROGRAM AND

PROVIDES FIRST YEAR UPDATE FOR THE CLARE ZINC PROJECT IN IRELAND

Vancouver, Canada – Hannan Metals Limited (“Hannan” or the “Company”) (TSX.V: HAN) (OTCPK: HANNF)

is pleased to present an update on exploration completed for the last year and announce plans are underway for a major

drilling program to test geological, seismic and soil targets on its Kilbricken zinc-lead-silver prospect near Ennis and on

other prospects in the group’s extensive prospecting licence area in Co. Clare, Ireland.

Key points:

 Following a successful exploration pr ogram completed by Hannan over th e last year, the Company is now

planning a 20,000 metre drill program to test geological, seismic and soil targets generated both at Kilbricken and

across Hannan’s large Clare prospecting licence. Immediate priorities on the regional basin-scale are structural

trends evident in seismic data that coincide with seven significant geochemical targets within a 12 kilometre

untested trend.

 Hannan’s first year diamond drill program comprised 12 holes for 6,492 metres and focused on expanding the

Kilbricken resource. Many drill holes intersected signific ant mineralization which extended both the Fort and

Chimney Zones (Tables 1-2, Figures 1-2). Drill highlights include DH 17-3679-217 (“DH217”) at the Fort Zone,

that was one of the most mineralized ever drilled at the property:

o 8.0 metres @ 4.1% Zn, 33.7% Pb and 174 g/t Ag (37.9% Zn+Pb) from 528 metres;

o 3.4 metres @ 5.2% Zn, 4.3% Pb and 33 g/t Ag (9.5% Zn+Pb) from 570 metres;

o 26.6 metres @ 7.5% Zn, 0.9% Pb and 14 g/t Ag (8.4% Zn+Pb) from 588 metres;

 A maiden resource1 was established comprising 2.7 million tonnes at 8.8% zinc equivalent (“ZnEq”), including 1.4

million tonnes at 10.8% ZnEq indicated and inferred resour ces of 1.7 million tonnes at 8.2% ZnEq, including 0.6

million tonnes at 10.4% ZnEq. for Kilbricken, which immedi ately ranked it as one of the top ten base metal

deposits in Ireland by tonnes and grade (data sourced from the Irish Exploration, Mining Division website);

 Close to 1,000 surface geochemical samples were collected which defined seven new anomalous areas within a

12km by 2km long north-west trending multi-element geochemical anomaly;

 A 40.6 line kilometre 2D seismic survey that delivered a critical new set of subsurface data across much of the

Clare prospecting licence;

 Locked cycle metallurgical testwork on massive sulphide mineralization from Kilbricken is now underway with

Wardell Armstrong with results available Q2 2018;

 Hannan has now made all cash payments totaling US$1,000, 000 (€810,000) to Lundin Mining Ltd to complete its

purchase of the project. Lundin will retain a 2% net sm elter return royalty on all sales of mineral products

extracted from the project area, subject to certain buy back provisions.

Mr Michael Hudson, Chairman & CEO states, “We are delighted with the progress we have made over the last year since

listing. After completing our purchase from Lundin Mining we now own one of the few high-grade zinc-rich sulphide

discoveries made over the last decade in Ireland within a st rategically important, regional-scale land package. We have

established a maiden resource estimate which our drilling has already expanded, while our seismic and geochemical work

has unlocked the potential which will form the basis for current and future drilling targets.”

After raising a total of C$4.8M in February and August 2017, Hannan has quickly progressed to become one of Ireland’s

leading exploration companies. The Irish midlands are a high pedigree zinc district, long favoured by major mining

companies due to the presence of large high-grade deposits often with simple process flowsheets and high value low

impurity concentrates. Hannan’s work to date at the Clar e project has focused on the capture of new data, including

extensive drilling, geological, seismic and geochemical work programs within its large pros pecting licence package. The

exploration team has completed all work safely, to plan, and to budget with full community cooperation, and is now

2

planning for follow-up work on a range of resource expansion to regional scal e targets with 20,000 metres of drilling,

which remains subject to further financings during 2018/19.

Twelve holes have been completed by Hannan at Kilbricken for a total of 6,492 metres over the last year. Since discovery

of the Kilbricken resource ten years ago, total drilling on the project comprises 163,017 metres with an estimated

US$30,000,000 spent on exploration.

Hannan’s drilling initially focused on expand ing the resource at Kilbricken with the many holes intersecting significant

mineralization and extending both the Fort and Chimney Zones (Figures 1-2). The true thickness of mineralized intervals

at Kilbricken is interpreted to be greater than 95% of the sampled thickness. Drill highlights include:

DH 17-3679-217 (“DH217”) at the Fort Zone, one of the most mineralized ever drilled at the property:

 8.0 metres @ 4.1% Zn, 33.7% Pb and 174 g/t Ag (37.9% Zn+Pb) from 528 metres, including 3.2 metres @ 8.4%

Zn, 72.8% Pb and 388 g/t Ag (81.2% Zn+Pb) from 528 metres;

 3.4 metres @ 5.2% Zn, 4.3% Pb and 33 g/t Ag (9.5% Zn+Pb) from 570 metres;

 26.6 metres @ 7.5% Zn, 0.9% Pb and 14 g/t Ag (8.4% Zn+Pb) from 588 metres, including18.8 metres @ 8.8%

Zn, 1.1% Pb, 19 g/t Ag (9.9% Zn+Pb) from 588 metres;

DH 17-3679-218 (“DH218”), drilled at Fort Zone intersected massive sulphides within a down-hole thickness of 55 metres:

 4.0 metres @ 0.7% Zn, 8.9% Pb and 31 g/t Ag (8.6% Zn EQ) from 526 metres, including 1.4 metres @ 1.6% Zn,

15.2% Pb and 53 g/t Ag from 526 metres and 1.0 metres @ 0.4% Zn, 13.8% Pb and 46 g/t Ag from 529 metres;

 6.0 metres @ 2.5% Zn, 1.8% Pb and 13 g/t Ag (4.4% Zn EQ) from 544 metres, including 2.1 metres @ 5.0% Zn,

3.7% Pb and 25 g/t Ag from 548 metres;

 6.4 metres @ 4.8% Zn, 1.3% Pb and 15 g/t Ag (6.3% ZnEQ) from 558 metres, including 1.1 metres @ 13.3%

Zn, 3.1% Pb, 34 g/t Ag from 558 metres;

 10.0 metres @ 3.4% Zn, 1.0% Pb and 13 g/t Ag (4.7% ZnEQ) from 571 metres;

DH 17-3679-219 (“DH219”), a 50 metre step out hole from the Fort Zone intersected massive sulphide mineralization

within a total down-hole thickness of 92.9 metres:

 8.4m @ 8.0% ZnEQ (6.2% Zn, 0.9% Pb, 15 g/t Ag and 0.35% Cu) from 599.0m, including 1.4m @ 20.8%

ZnEQ (16.8% Zn, 3.5% Pb, 30 g/t Ag, 0.2% Cu) from 604.0m

 12.8m @ 5.1% ZnEQ (3.2% Zn, 1.8% Pb, 13g/t Ag and 0.05% Cu) from 631.5m, including 0.9m @ 17.8%

ZnEQ (15.3% Zn, 2.1% Pb, 25 g/t Ag, 0.1% Cu) from 643.4m

DH 17-3679-220 (“DH220”) first drill hole to test along strike from the Chimney Zone, was a 75 metre step out:

 3.3m @ 10.4% ZnEQ (3.6% Zn, 6.5% Pb, 58 g/t Ag and 0.1% Cu) from 477.0m, including 1.0m @ 18.6%

ZnEQ (3.7% Zn, 14.5% Pb, 121 g/t Ag, 0.2% Cu) from 478.6m

The remaining eight drill holes of the 2017 program (DH 17-3679-221 through to DH 17-3679-229; DH 17-3679-225 was

abandoned at 72 metres) (see Tables 1 an d 2 and Figure 1) were drilled outside the Kilbricken resource area, based

primarily on soil anomalies. Hole 17-3679-221 intersected anom alous copper mineralization 300 metres along strike from

the Fort Zone. Hole 17-3679-226, drilled up dip from the re source area, intersected hematite alteration which is

considered a good indicator of proximity to mineralization . Drill hole 17-3679-228 contained bo th pyrite at the base of

reef with intense dolomitization and a fa ult in the stratigraphic footwall, which in dicates a drill target at shallower levels

up-dip of from the resource area. The remaining five holes did not intersect significant mineralization or alteration (Figure

1).

A maiden resource1 estimate was calculated for the Kilbricken project by Hannan using drill hole data acquired prior to

Hannan’s involvement in the project. A total indicated mineral resource of 2.7 million tonnes at 8.8% zinc

equivalent (“ZnEq”), including 1.4 million tonnes at 10.8% ZnEq and a total inferred mineral resource of 1.7 million

tonnes at 8.2% ZnEq, including 0.6 million tonnes at 10. 4% ZnEq was calculated. This resource estimate

immediately ranks Kilbricken as one of the top ten base meta l deposits discovered in Ireland by tonnes and grade (data

sourced from the Irish Exploration, Mining Division website);

Geochemical sampling grids at Hannan’s Clare County project now cover >200 km2 with a soil sample spacing of 500m x

250m (Figure 2). Over the Kilbricken prospect, a 30 km 2 area was covered with a denser grid with 250m x 250m spaced

3

samples. Recent sampling by Hannan now comprises a total of 961 samples and has defined seven new anomalous areas,

including a 12km by 2km long north-west trending multi-elem ent geochemical anomaly. Within this trend there are four

Kilbricken-sized multi-point anomalies which have never been drill tested, including a southerly extension to the

Ballyhickey historic mine (Figure 2).

Late in 2017 a 40.6 line kilometre 2D seismic survey was carried out on the Company’s 100%-owned County Clare zinc

project, which hosts the Kilbricken zinc-lead-silver deposit in Ireland. The regional seismic survey is a first for the area

and has delivered a critical new set of subsurface data across Hannan’s 35,444 hectare prospecting licence (Figure 1),

which will form the basis for current and future drill targetin g and prioritization. Combined with earlier surveys Hannan

now owns 68 kilometres of 2D seismic and a 1.5 square kilometre 3D seismic survey. Hannan has also invested

considerable time processing historic seismic data acquired in 2011 and 2012 by ea rlier operators, to further refine the

structural architecture on the project.

Hannan commenced locked cycle metallurgical testwork ut ilizing the services of Wardell Armstrong late in 2017 and

results will be available during Q2 2018. During 2017 the Company announced the results of a gap analysis on

mineralogical investigations on the Kilbricken project, Ireland by Dr. Kurt Forrester of Arn Perspective Ltd. Based on this

study and the available information, it is likely a conventional lead-zinc flotation circuit at Kilbricken should produce a

saleable mineral concentrate.

The Company also commenced a formal technical collaborati on and agreement with iCRAG at the University College

Dublin during 2017. iCRAG is an EU and industry funded resear ch centre with experts in Irish mineral deposits which will

aid in geological understanding and targeting of additional mineralization on Hannan’s Clare licences.

Hannan has now made all cash payments totaling US$1,000,000 to Lundin Mining Ltd to complete its outright purchase of

the project. The project was assigned to Hannan, and wa s acquired, effective September 21, 2016, pursuant to an

Assignment Agreement between the Irish Minister for Comm unications, Climate Action and Environment, Hannan and

Lundin Mining Exploration Limited (“Lundin”), a subsidiary of Lundin Mining Corporation (TSX:LUN). Under a separate

Asset Purchase Agreement, dated June 3, 2016, Hannan purcha sed all exploration data associated with the project from

Lundin for a cash payment of US$150,000. Hannan has no w made two additional cash payments to Lundin of

US$425,000 each in September 2017 and March 2018. Lundin will re tain a 2% net smelter return royalty on all sales of

mineral products extracted from the project area, subject to a 0.5% buy back right of Hannan for US$5,000,000, which

must be exercised within one year from the date of commercial production. Hannan is required to pay Lundin a one-time

bonus payment of US$5,000,000 within the ea rlier of (i) Hannan Ireland’s decision to proceed with mine construction or

(ii) within 90 days of the establishment of a commercial financing to finance capital costs for mine construction.
