Gold and Base Metals explorer Auris Minerals Limited provided the following update on exploration completed by Sandfire Resources Limited during the March 2022 quarter across the Joint Venture Projects located in the Bryah Basin, Western Australia. MORCK WELL JV (SFR earning a 70% interest): Project Summary In February 2018, Auris entered a Farm-in Agreement with SFR in relation to the Morck Well and Doolgunna Projects which covers 430km². The Morck Well and Doolgunna Projects are strategically located 22km to the south-west and 4km to the southeast respectively, of Sandfire's DeGrussa Copper Mine in Western Australia.

The Morck Well project is also located 8km along strike from Sandfire's Old Highway gold deposit with comparable high-grade gold mineralisation being intersected associated within similar geology within regional Air Core drilling completed to date. Air Core Drilling Results were recently received for 15 holes (MWAC4242 ­ MWAC4256), completed in the December 2021 quarter. This programme was designed as a 400x100m infill pattern to provide high quality litho- geochemical data and key geological information to delineate the upper Narracoota stratigraphy, known to be host to VMS-style mineralisation.

No significant results were received. RC Drilling Two RC drill holes (MWRC0051 and MWRC0052) for 327m were completed to further evaluate interpreted supergene enrichment intersected at the base of complete oxidation within previous air core drilling including: 10m @ 0.42% Cu from 40m incl 5m @ 0.64% Cu from 40m - MWAC2870 15m at 0.46% Cu from 55m incl 5m at 0.89% Cu from 65m ­ MWAC3356 MWRC0051 was abandoned after 34m and the hole re-designed, MWRC00052, intersected significant copper, zinc and lead mineralisation and 2m of trace native copper between 118-120m. The drill hole encountered an extended weathered profile, intersecting weathered upper saprolite down to 136m, interpreted to be associated with preferential weathering along a structure.

Further RC drilling is being planned to test down dip and along strike to further evaluate the mineralisation intersected to date.

CHEROONA JV: RC precollar and diamond tail completed. Drilling was designed to target DeGrussa host stratigraphy and prospective structures. Results from 392.9m diamond tail are pending.
