HANNAN SUBMITS DECLARACION DE IMPACTO AMBIENTAL (DIA) FOR THE TABALOSOS

PROJECT, PERU

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

HANNF) is pleased to announce the com pletion and submission of its Declaracion de Impacto

Ambiental (“DIA”) or Environmental Impact Statement /g4at its Tabalosos East copper-silver project in Peru. The

DIA is the primary environmental certification required to allo w low impact mineral exp loration programs, that

includes drilling programs, to proceed in Peru.

Highlights:

 The area for the DIA allows for 40 drill platforms and covers an area approximately 9 kilometres long

and 3 kilometres wide (2,700 hectares), at Tabalosos East (Figures 1 and 2);

 The copper mineralized shale drill target at San Martin averages 0.9 metres thickness at 1.9 % copper

and 27 g/t silver from 105 surface channels and has been further defined by soil sampling and LiDAR

over an area of 9-kilometre-long by 1-kilometre-wide area that is interpreted to extend with shallow

dips to the west for between 2-4 kilometres, with a target depth ranging from surface to 500 metres;

 Drilling tenders are being sought now and final DIA and other a pprovals are anticipated during the

second half of 2022 to allow drilling to start.

Michael Hudson, CEO, states “The submission of our DIA is a major milestone for Hannan. Our maiden low

impact drill program will consist of up to 10 drill platforms to thoroughly test the extensive copper-shale horizon

with holes up to 500 metres depth. We are thankful for all the detailed work of our employees and external

experts and the support of the local communities during the public participation meetings, as well as the advice

from various government agencies. The first drill program at San Martin will be a watershed moment, with the

opportunity to outline the scale and grade of the extensive cop per-rich shale horizon into the third dimension

after mapping continuity of the copper mineralized shale over a 9 - k i l o m e t r e x 1 - k i l o m e t r e s u r f a c e a r e a a t

Tabalosos.”

Work for the DIA included professional archaeological investigations, community workshops and liaison activities

to collect appropriate information necessary to make the submit tal for approval to the General Directorate of

Mining Environmental Affairs of the Ministry of Energy and Mines, Peru. The work program included:

 Environmental baseline monitoring for the project, conducted by third party experts;

 The Peruvian Ministry of Culture granted the CIRA (Certificate of non-existence of archaeological remains)

which declares that the project does not impact archaeological sites;

 Public participation meetings outlining Hannan’s exploration pl ans were held in the hamlets of Pucayoc

and Cunchiyacu, where the communities are on record as approvin g of the company’s proposed drill

program;

The DIA is the primary environmental certification required to allow low impact mineral exploration programs,

that includes drilling programs, to proceed in Peru. Final DIA and other approvals are anticipated during Q3

2022. Drill tenders are now being sought and Hannan continues t o explore, derisk and develop drill targets

within the large area at Tabalosos.

Tabalosos Copper-Silver Project

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. KGHM Polska Miedz’s

(“KGHM”) three copper-silver sediment-hosted mines in Poland (t he “Kupferschiefer”) were the leading silver

producer in the world and seventh largest global copper miner i n 2020. Quoted resources in 2019 for KGHM

were 1,518 Mt @ 1.86% copper and 55 g/t silver from a mineralized zone that averages 0.4 metres to 5.5 metres

thickness.

To provide context, Hannan’s widths and grade (0.9 metre @ 1.9 % copper and 27 g/t silver) from 105 channel

surface samples reported at San Martin (lower cut 0.5% copper), within an area about 9 kilometres long and 1

kilometre wide, compare with those found during the initial mode rn-day drill discovery of the

Kupferschiefer copper-silver deposits (Figure 2).

 In 1957 the discovery drillhole (Sieroszowice IG 1) intersected 2.0 metres @ 1.5% copper at the depth

of 657 metres.

 In 1959 the Lubin-Sieroszowice deposit, based on the results fr om 24 drillholes contained 1,365 Mt @

1.4% copper and 26 g/t silver in indicated resources, with a thickness ranging between 0.2–13.1 metres

in an area about 28 kilometres long and 6 kilometres wide between 400 metres and 1,000 metres depth.

Hannan’s sampling, to date, has been confined to surface channel sampling, although mineralization at Tabalosos

East is interpreted to extend with shallow dips to the west for between 2-4 kilomet res, with a target depth

ranging from surface to 500 metres (Figure 3).

Technical Background

All mineralized samples were collected by Hannan geologists. Sa mples 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 with barren material after every sample. Samples were analyzed by

method ME-MS61, a four acid digest preformed on 0.25g of the sample to quantitatively dissolve most geological materials.

Analysis is via ICP-MS. Channel samples are considered represen tative of the in-situ mineralization samples and sample

widths quoted approximate the true width of mineralization, while grab samples are selective by nature and are unlikely to

represent average grades on the property.

All soil samples were collected by Hannan geologists using an i n-house protocol for soil sampling in jungle areas. The

samples were subsequently analyz ed with a portable XRF deployin g a protocol developed by Hannan for the San Martin

project. The method is designed to minimize risk of contaminat ion and ground disturbance. In most cases the sample

media is the “B-horizon” of the soil profile. Only 100g of sample material is collected from each site. From the soil sample

a pellet is being produced which is dried and analyzed by a por table XRF (pXRF). Certified reference material, blanks and

field duplicates are routinely added to monitor the quality of the pXRF data. Gold was analyzed by ALS in Lima using a

standard sample preparation and 50g fire assay sample charge.
