Enterprise Metals Limited Reports Mutiple Anomalous Gold Intercepts from Rc Drill Program
Enterprise Metals Limited reported that the first stage slimline reverse circulation (RC) drilling program at Mandilla was completed on 30 April 2021. 22 angled RC holes (1,808m, av. length 82m) were drilled to follow up results from Enterprise's 2020 aircore program and an Induced Polarisation (IP) survey completed in March 2021. Assay results have been received for 4 metre composite samples from the April drilling program. Enterprise's target at Mandilla is primary gold mineralisation, similar to that discovered on the western margin of the Mandilla Syenite by Anglo Australian Resources NL ("Anglo", ASX: AAR). AAR's drilling has demonstrated that shallow low grade gold intersections in saprolite and saprock may overly primary gold mineralisation. The three areas drill tested in the April program were: 3D-Induced Polarisation chargeability anomaly south of the Mandilla homestead, a gold-arsenic anomaly on the Ausrox Shear Zone (MEAC081 anomaly), and a gold-arsenic anomaly on the eastern margin of the Mandilla Syenite (Star anomaly). Four angled slimline RC holes (MERC005 and MERC015-017, total 300m) were drilled on three east-west lines, GDA94: 6528500N, 6528600N and 6528700N, to follow up a previous aircore result in MEAC081 of 12m @ 0.7 g/t Au and 586 ppm As from 32m, including 4m @ 1.8 g/t Au and 211 ppm As from 40m downhole, within a deeply weathered 60m zone averaging 615ppm As. All holes intersected fresh rock (silica flooded and quartz veined feldspar porphyry) with sulphides predominantly 1% -3% pyrite, and low gold contents at or below 50-60m downhole, which include, MERC005: 4m at 0.22g/t Au from 4m, and 48m at 370ppm As and 8ppm Sb from 8m MERC016: 28m at 25ppb Au and 8ppm Sb from 32m downhole, and MERC017: 36m at 6ppb Au and 10ppm Sb from 28m downhole to end of hole. Four angled slimline RC holes (MERC018-022, total 354m) were drilled on two east-west lines, GDA94: 6529100N, 6528800N, to follow up 2020 vertical aircore intersections which included MEAC055: 13m at 427ppm As from 12m depth to end of hole, and MEAC067: 8m at 47ppb Au from 32m depth to end of hole. These holes intersected sheared fresh rock (siliceous and quartz veined feldspar porphyry) with sulphides predominantly 0.1% - 1% pyrite, at or below 40-50m downhole. MERC018: 45m at 31ppb Au from 28m to bottom of hole, including 4m at 0.21g/t Au, 1.3ppm Bi and 2.7ppm Sb from 48m downhole. MERC019: 4m at 0.16g/t Au, 105ppm As and 6.3ppm Sb from 32m. Thirteen angled slimline RC holes (MERC001-004 and MERC006-014, total 1,154m) were drilled on two east-westlines, GDA94: 6527600N and 6527500N. Eleven holes intersected fresh rock (biotite rich and sheared felsic porphyry) with sulphides predominantly 1% - 3% pyrite, at between 50-60m downhole. These holes recorded low levels of gold in 4m composite samples, with between 1 and 8ppb gold in fresh rock, with minor associated silver (0.1ppm - 0.74ppm). Two holes (MERC007 and 008) intersected pyritic black shales with similar pyrite content and between 1 and 5ppb gold in fresh rock below 50-60m downhole. The Mandilla Prospect is located in the northern Widgiemooltha greenstone belt in the western part of the Kalgoorlie geological domain, some 100 kilometres south of Kalgoorlie by road and 20 kilometres south west of Kambalda. Significant nickel and gold deposits are present in the belt, the nearest mined gold deposit being the high-grade Wattle Dam Mine located approximately 3 kilometres to the west of Mandilla. Enterprise's Mandilla Prospect is comprised of granted Exploration Licence 15/1437 and Prospecting Licence 15/5885, both held in the name of Vera Olive Allen. The Mandilla Prospect lies on the margins of a porphyritic intrusion, the Mandilla Syenite. The syenite intrudes volcanoclastic sedimentary rocks in the area which form part of the Spargoville Group. Significant NW to WNW and NE trending structures along the western flank of the tenements are interpreted from regional aeromagnetic data to cut through the Mandilla Syenite and may be important in localising gold mineralisation within the Mandilla Syenite. Enterprise's recent limited Stage 1 scout RC program has recorded some encouraging assays of gold and associated pathfinder elements in 4 metre composite "scoop" samples that further point to the eastern margin of the Mandilla Syenite/granite intrusive complex being prospective for gold. The Company is currently collecting from the field original 3kg 1m samples for analysis.
