Asian Battery Metals PLC (ASX:AZ9) has enhanced the prospectivity of the Oval Copper-Nickel-PGE Project within the broader Yambat Project in Mongolia through the intersection of massive sulphides in a drill hole around 100 metres away from a previous intersection.
Drill hole OVD026 in the main part of the Oval gabbroic intrusion intersected 19.3 metres of combined mineralisation of massive-semi massive, moderate to dense disseminated, net textured sulphide from 91.2 metres down hole.
This included 1.9 metres of massive sulphide from 105 metres and 2.4 metres of semi-massive sulphide from 102.6 metres.
OVD026 is 100 metres northwest of the previous 8.8-metre massive sulphide intersection identified in drill hole OVD021.
All assays are pending and will be finalised within the next 5 to 6 weeks.
May represent extension
Asian Battery Metals said the massive sulphide intersection in OVD026 was of particular significance due to its location within the Oval area, around 100 metres northwest of the previous intersection identified in drill hole OVD021.
This intercept may represent an extension of the known massive sulphide mineralisation in the area and highlights the potential for further expansion of massive sulphide zones within the broader prospect area.
To date, five drill holes - OVD022, OVD023, OVD024, OVD025 and OVD026 - have been successfully completed in the Phase 2 drilling program.
Testing DHEM conductor
Hole OVD026 was designed to test a Down-Hole Electromagnetic (DHEM) conductor plate identified as OVD007_L2_B which exhibits a conductance of 1,000 siemens. This was a reinterpretation of OVD007_L2_A by Southern Geoscience Consultants.
This low conductivity plate was previously discounted as being significant owing to its low conductivity, modelling uncertainty and low correlation to then-understood geology.
The OVD007_L2_B plate was measured in drill hole OVD007 based on DHEM survey down to only 60 metres in the drill hole due to blockage.
Hole OVD026’s average mineral content was 3.0% chalcopyrite, 2.0% pentlandite, 27.0% pyrrhotite and 2.0% pyrite based on visual estimates.
The complete mineralised intersection consists of 87 metres of trace mineralised gabbro, 3.6 metres of moderately disseminated mineralised, 4.8 metres of densely disseminated mineralised, 6.6 metres of net-textured sulphide mineralised gabbro, 2.4 metres of semi-massive sulphides and 1.9 metres of massive sulphide mineralisation.
True thickness of the massive sulphides is 1.4 metres.
Semi-massive mineralisation from 102.6 metres to 105 metres has geological characteristics of massive sulphide stringers, veins and sulphide-matrix breccia within net textured sulphides.
