ABSTRACT:Great Northern Minerals Limited (“Great Northern Minerals” or the “Company”) (ASX: GNM) is pleased to announce the receipt of assay results from the remaining six Reverse Circulation (RC) drill holes at the Company’s Big Rush Gold Project in Northern Queensland (Figure 1). Best intersections, calculated at nominal 1 g/t cutoff, are highlighted below with detailed data in Table 1. A total of 8 RC drill holes for 1,042 metres were completed at the project in early December 2019. All holes tested mineralisation beneath the historical Central Pit workings (Figure 2) along 200m of strike length, notionally, 75m below original surface and up to 60m below the pit floor. Samples were collected for each metre and split through a rig-mounted cone splitter with 10% of each sample (approximately 2.5-3kg) collected in a calico sample bag for assay and bulk samples stored on site in plastic bags. Gold assays were all by fire assay. Only very minor water was encountered and all samples were dry and of even volume. The objective of the programme was to validate previous drilling results to enable a maiden JORC-compliant resource to be calculated. Analyses have confirmed the width and grade of historic drill intersections and resource estimation work has commenced.
