ABSTRACT:Great Boulder Resources [ASX: GBR] is pleased to report on the results of recent drilling at its Winchester copper-nickel sulphide project in Western Australia. Four holes were drilled at Winchester in late March as part of an EIS co-funded drilling program. Two deeper diamond holes were drilled to test down-plunge positions of the main sulphide mineralization, while two RC holes were drilled to test positions to the north and northwest of Winchester. Diamond hole 20WNRCD002 intersected 4.4m @ 0.8% Cu, 4.7g/t Ag, 0.08% Ni and 0.01% Co from 201.86m within the main sulphide shoot, including 1.14m @ 1.3% Cu and 6.7g/t Ag in a higher grade zone. This mineralisation sits approximately 250m down-plunge from the interpreted top of the shoot, or 80m down-plunge from the nearest drill hole. Mineralisation remains open to the west and at depth. Hole 20WNRCD001 was designed to test the structure approximately 100m east and down-plunge of 20WNRCD002. This hole did not intersect any significant Cu-Ni mineralisation. It was extended through a black shale marker horizon to allow a down-hole EM survey to be conducted at a later date, to test for further sulphide conductors at depth.
