Aurumin Limited announced high-grade assays have been received from the November Reverse Circulation (RC) drilling at its 100% owned Mt Dimer Project, located 120km north-east of Southern Cross in Western Australia. Mt Dimer is a historical high-grade production centre, having produced over 125,000 ounces of gold, including open pit and underground production of 600,000 tonnes @ 6.4 g/t Au. RC drilling occurred at four deposits at Mt Dimer. Highlights from ech deposit (1m samples) include: Lightning is a high-grade unmined deposit at Mt Dimer. Mineralisation consists of multiple narrow high-grade quartz bearing ore shoots plunging steeply to the north, within a northerly trending structure primarily hosted by granite. Four holes were drilled in the November programme to follow up the northerly extensions of the deposit surrounding Aurumin's July intercept of 4m @ 48.69g/t Au, including 1m @ 153.50g/t Au (LTRC2106 - ASX release 01/09/2021). MD_LT_RC_21_0009 returned 8m @ 15.00g/t Au including 2m @ 57.35g/t Au and 1m @ 90.70g/t Au from this work. Additionally, three holes were drilled perpendicular to the ultramafic contact to test for mineralisation running along the lithological contact (not pictured on long section). These holes returned road lower grade mineralisation, including 5m @ 0.81g/t Au in MD_LT_RC_21_0013. The LO3 deposit is one of the three LO deposits mined in the mid 1990's at Mt Dimer. It has an open pit of similar scale to LO1 and LO2, however, unlike LO1 and LO2, has limited underground workings. The orebody has not been closed off along strike or below the underground workings and remnant potential exists directly below the open pit. Five holes were drilled in the November programme testing northerly extensions and depth extensions of high grade shoots. Highlights of the latest round of drilling include 4.0m @ 2.58/t Au including 1m @ 8.98g/t Au in MD_L3_RC_21_0014, located within a potential new structure parallel to the main ore body (not pictured on long section) and 2m @ 3.11g/t Au on the target structure in MD_L3_RC_21_0013. These results confirm the potential for future further extensions to the north and at depth, and also offer opportunity to follow up the potential new parallel structure. The southern extension of LO3 was not tested during this round of drilling and is still considered an attractive target. Frodo is a high-grade deposit at Mt Dimer previously mined as an open pit and has had limited underground work. Mineralisation consists of multiple narrow high-grade quartz bearing ore shoots plunging to the south, within a northerly trending structure primarily hosted by granite. Three holes were drilled during the November work, testing depth extensions. MD_FO_RC_21_0002 returned 2m @ 28.94g/t Au including 1m @ 50.10g/t Au. The remaining two holes did not return significant results, this has led to a review of the interpreted orientation of the mineralisation and a refining of high grade plunges targets.
