Auris Minerals Limited provided the following update on exploration activities completed during the December quarter 2019 within the Morck Well and Cashman Joint Ventures with Sandfire Resources Limited in the Bryah Basin, Western Australia. Air Core Drilling: Regional air core (AC) drilling continued at the Tetris Prospect, with 222 drill holes (MWAC1968 - MWAC2000, MWAC2015 - MWAC2195 and MWAC2201 - MWAC2208) completed for a total of 15,025m. First pass air core drilling has now been completed at the Tetris Prospect.

All results from the completed drilling have been received and significant assays of 5m @ 1,080ppm Cu from 30m and 5m @ 1,290ppm Cu from 40m were returned from MWAC2139. Reverse Circulation (RC) Drilling: Five Reverse Circulation (RC) drill holes (MWRC0042 - MWRC0046) were completed within the Morck Well JV for a total advance of 2,092m. One drill hole (MWRC0042) was completed for 354m at the Tetris Prospect.

Drilling targeted an AEM geophysical anomaly and prospective stratigraphy along strike from Morck Well. Two drill holes (MWRC0043 and MWRC0044) were designed to test prospective geology and anomalous geochemistry along-strike from significant intercepts intersected in MWDD0004 and MWRC0010, including 10m @ 2,966ppm Cu from 175m, (MWRC0010). A further two drill holes (MWRC0045 and MWRC0046) targeted a MLEM anomaly identified from testing with the new ARMIT sensor.

No significant assays were received from RC drilling within the Morck Well JV. Results for MWRC0046 are pending. Geological Understanding: MWRC0042 intersected mostly dolerite, however a narrow package of chlorite altered sediments including siltstone, quartz arenite and wacke and minor sedimentary conglomerate was intersected.

This confirms the presence of prospective DeGrussa Member (Karalundi Formation) stratigraphy in the Prospect area. Air core drilling has intersected varying stratigraphy, confirming that the typical Doolgunna Formation, Karalundi Formation and Narracoota Formation stratigraphic relationships exist moving south-west along-strike from the Morck Well Prospect area. A review has been ongoing to ensure air core drilling is identifying the relationship between Magazine Member and DeGrussa Member of the Karalundi Formation, to enable better constrained and effective targeting.

MWRC0043 intersected a package of strongly chlorite altered and exhalative sediments with minor jasper and pyrite and chalcopyrite mineralisation, confirming the presence and continuation of the host sediment horizon to the south-west of MWRC0010 and MWDD0004. MWRC0044 intersected a thick sedimentary horizon of mostly sedimentary and minor mafic-derived conglomerates with only thin packages of chlorite altered siltstone in between. The strongly chlorite altered and exhalative sediments observed in MWRC0043 were not intersected in MWRC0044, suggesting that the geological interpretation requires a review in the immediate vicinity of the drill hole.

MWRC0045 was drilled relatively high in the Karalundi stratigraphy, close to the interpreted base of the Narracoota Formation. The stratigraphic position is higher than where typical anomalism is encountered elsewhere in the basin. The drill hole intersected predominantly sediments including mixed siltstone, arenites and wackes, with minor dolerite.

Of interest was a package of haematitic and exhalative sediments with minor chlorite and magnetite. MWRC0046 intersected a large package of silicified basalt and mafic derived conglomerate and breccia. Given that this drill hole is located 200m adjacent to MWRC0045, the significant change in intersected geology along-strike indicates possible structural complexity around the target MLEM plate.

Reverse Circulation (RC) Drilling: Two RC exploration drill holes (CHRC0003 and CHRC0004) were completed for a total advance of 694m within the Cashman JV. Drilling was designed to target anomalous geochemistry intersected in Air core and RC drilling completed by Auris adjacent to the Orient prospect. Geological Understanding: CHRC0003 intersected interbedded dolerites and sediments indicating the presence of prospective sedimentary package of the Degrussa Member.

The hole successfully intersected a magnetite and haematite exhalite sequence with jaspers and disseminated pyrite throughout, a potential indicator of nearby VMS systems. CHRC0004 intersected a thick package of varied sediments and mafics and no significant mineralisation of geologically favorable indicators were observed. Initial interpretation is that this drill hole may be drilled too low in the stratigraphy and intersected Magazine member lithologies of the Karalundi Formation. Drilling of the regional first pass air core programme has identified Doolgunna Formation, Karalundi Formation and Narracoota Formation lithologies, suggesting the stratigraphic relationships seen at the Ruby Well and White Well Prospects (Enterprise Project) continue south-west through the Cashman JV.

Integration with significant field mapping and geophysical datasets is suggesting structural complexity exists throughout the Cashman JV area with possible stratigraphic repeats, affecting ongoing interpretation and targeting.
