BACKGROUND INFORMATION Galena Mining Limited (Galena) acquired exploration tenements in the Peak Hill mineral field in the Gascoyne region of Western Australia in 2017. These tenements contained the Abra base metals deposit. Exploration drilling further defined the mineral resource to the point that Galena prepared a Pre- Feasibility Study and then a Definitive Feasibility Study, to develop the deposit into an operational mine. On 12 April 2019, Galena provided an announcement to the Australian Stock Exchange that Toho Zinc Co. Ltd (Toho), via its wholly owned subsidiary CBH Western Australia Pty Ltd (CBHWA), had invested in a 40% joint venture in Abra Mining Pty Ltd (AMPL), to develop the Abra base metals project. The project, known as the Abra base metals mine, involves underground mining, base metals (lead /silver) concentrate production via floatation processing and road transport of the concentrate to the Port of Geraldton for export. The Abra project is located in the eastern Gascoyne region, approximately 180 kilometres north of Meekatharra (Figure 1). There are three occupied pastoral lease homesteads around the Abra project; Tangadee – approximately 40 km north east; Woodlands – approximately 40 km west south west and Mingah Springs- approximately 40 km south east. The Mulgul pastoral station homestead is unoccupied. The mine has an approximate life span of 15 years based on the planned production rate. The initial project Mining Proposal ID 76773 was approved on xxxx Due to a number of factors, some components of the project could not be included in the initial mining project scope and required new tenements to be lodged. For this reason, this infrastructure was excluded from Mining Proposal ID 76773 while the tenement lodgment and grant process occurred. Now that grant of this tenure has either occurred or is expected to occur within the assessment timeframe of the application, this Mining Proposal amendment seeks to add these infrastructure components in to the overall Abra project EGS. This clearing permit application does not include clearing on the communications tenements (L52/205; L52/206 and L52/207). These tenements are very small, with the communication facility component occupying an area of only 50m x 50 m. The extent of infrastructure and possible disturbance required on the tenement is likely to be even smaller. Figure 2 and Figure 3 show examples of the type of containerised and modular infrastructure required to be located on these tenements occupies the approximate footprint of a passenger car. This can usually be located on the tenement with little or no clearing. In any event, there is an exemption for miscellaneous clearing on a tenement of up to 10 hectares per year. In the case of the communication tenements, the total area of the tenement is 0.25 ha. Any clearing required on these tenements will be well under the exemption threshold. 1 W E E L A R R A D N A A O E T R H S E N 500000 600000 700000 800000 L 900000 W C O R D E E N K TO R R U O B H A S D A D OA NEWMAN ISSIO N R G M ON AL IG 0 J 0 ´ 0 0 0 4 7 AD A RO S K H EE D B R A UR C T E O ON P RE D R U R OWN EEKAT AIR T S M H S A ARR IE N A W N !( R D O O A A PORT HEDLAND D R R P R A A L IRI E E D E OW NS W RO A AD I N A V L Y S WEELA RRA W e s tt errn NA NO RTH B RO U PIN L A D A u s t r alia G L A u s t r alia AN O DY ROAD O D O W N ROAD S S R N O W A D O !( COBRA PERTH MOU D NT A Y UG E US L TU O S R O OADD 0 0 0 0 TANGADEE 0 3 7 L A N D O MOU NT AUGU R ST D U S WO M OD A LAN Legend O D O S R U R OA N D G T SITE LOCATION R Access to site A U U B D G L U A B Site Location E IE ROAD S YON D T W U WOODLANDS Principal Road S MULGUL R O D A A Secondary Road D RO MINGAH SP MARYMIA ROAD U L RIN ULG GS LL M R VERE O Minor Road DE A D RE ROAD T CLE Track UN MINGAH MO OR ND SPRINGS LA MILGUN M E E K A TH AR R A M DOWNS OAD O A LGETY LAN R U S DA DO R N H 0 T B 0 FORTNUM C U D 0 L R A 0 T E O 0 R O E R 2 R GOLD MINE N 7 O S A D O R D E W IV N R S E M E E R E H K T A W L T L IL H I U A H N A R K A N R E O A R P T R H YULGA JINNA O R O A A D D D A O R G N O Scale (A3) R 1:1,500,000 E Geocentric Datum of Australia 1994 B Datum E R Projection Map Grid Australia, Zone 50 IN G A R D Topography: Geoscience Australia, GEODATA Topo 250K R A Sources A O V3, © Commonwealth of Australia, 2006 C R BE U E L E L ELE 0 R A M D g003_IW186400_RegionalOverview_RevA (MR 18/07/2018) 0 O T H O A File 0 O A UN U R 0 D O N E 0 L M T A 1 H A 7 R MIL U EUR E A L NO I O M K AW JACOBS, 263 Adelaide Terrace, Perth WA 6000 A D R A Tel: +61 8 9469 4400 Fax: +61 8 9469 4488 R O A ROAD R K This map has been compiled with data from numerous sources with A E different levels of accuracy and reliability and is considered by the GOLD P authors to be fit for its intended purpose at the time of publication.

This document has been developed in support of a Purpose native vegetation clearing permit application. It has been prepared in accordance with requirements of the Environmental Protection Authority (EPA), the Department of Water and Environmental Regulation (DWER) and DMIRS. Clearing will be required to be undertaken from time to time to support the construction and operation of an aerodrome. Clearing will occur across mining tenement L52/198. A clearing area of up to 45.00 ha within a disturbance envelope of 265.00 ha is required to locate all project components. Figure 4 shows tenement L52/198 and the preliminary design of the aerodrome. 1.2 LAND OWNERSHIP The tenement covering this clearing permit application is L52/198. Holder- Abra Mining Pty Ltd. Status – Live.
