HANNAN ANNOUNCES FILING OF 43-101 TECHNICAL REPORT

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

announces the filing of an independent National Instrument 43-101 Technical Report on The Mineral Resource Estimate for

the Kilbricken Zinc-Silver-Lead-Copper Project Co . Clare, Ireland For Hannan Metals Ltd (the “ NI 43-101 Technical

Report”) in support of the Company’s news release dated July 10, 2017.

The NI 43-101 Technical Report was authored by Mr. Geoff Reed of Reed Leyton Consultants and Dr. John Colthurst who

are independent “qualified persons” as defined by National Instrument 43-101. The NI 43-101 Technical Report may be

found on the Company’s website at www.hannanmetals.com or under the Company’s profile on SEDAR at www.sedar.com.

Mr. Michael Hudson, CEO and Chairman, states: “The initial resource outlined in the technical report that was filed today is

a substantial start for the Company. Our aim is now to grow the initial zinc resource by drill testing the areas that lie open

in all directions around the resource area. We currently have one drill rig operating and after closing our recent financing,

will soon be mobilizing an additional drill rig. Drill results are expected to be released shortly.”

Highlights of the initial Mineral Resource Estimate for the Kilbricken Project, include:

 Total indicated mineral resource of 2.7 million tonnes at 8.8% zinc equivalent (“ZnEq”), including 1.4

millions tonnes at 10.8% Zneq;

 Total inferred mineral resource of 1.7 million tonnes at 8.2% ZnEq, including 0.6 million tonnes at 10.4%

ZnEq;

 This resource estimate is the first for the Kilbricken deposit, and immediately ranks it as one of the top ten

base metal deposits discovered in Ireland by tonnes and grade (data sourced from the Irish Exploration,

Mining Division website);

 Two styles of mineralization are evident at Kilbricken. The upper Chimney Zone demonstrates the classic

high-grade (>10% Zneq) Irish stratabound mineralization targeted by Hannan . This body has been

drilled within an area of 750 metres by 200 metres and av erages 12 metres thickness. The lower Fort Zone was

found later than the Chimney zone and has been tested with fewer drill holes. It is structurally hosted, lower grade,

but thicker, averaging 40 metres, and drilled within a 400 metre by 200 metres area.

 Importantly, the initial resource is expandable at all scales, from near resource to prospect scale, and Hannan

has already commenced a drill resource expansion program;
