The following Mineral Resource and Ore Reserves estimates are produced in accordance with the 2012 Edition of the Australian Code for Reporting of Mineral Resources and Ore Reserves (the 2012 JORC Code); Deflector, Rothsay, Daisy Complex, Lorna Doone, Maxwells, Santa, Cock-eyed Bob/Anomoly A, Lucky Bay, Mirror/Magic, Rumbles, Karonie, Harry's Hill, French Kiss, Spice, Tank/Artredies and Tank South. The remaining Mineral Resource and Ore Reserve estimates were first prepared and disclosed under the 2004 Edition of the JORC Code and have not been updated since to comply with the 2012 JORC Code on the basis that the information has not materially changed since it was last reported.

The information in these tables that relates to Mineral Resources and Ore Reserves has been extracted from the ASX Announcement entitled "2020 Mineral Resource and Ore Reserves Statement" dated 19 August 2020 which is available to view at www.silverlakeresources.com.au

Notes:

Mineral Resources and Ore Reserves stated as at 30 June 2020.

Mineral Resources are reported inclusive of Ore Reserves.

Data is rounded to thousands of tonnes, thousands of ounces gold and hundreds of tonnes of copper. Discrepancies in totals may occur due to rounding.
