| ABSTRACT: | Great Boulder Resources (ASX: GBR) is pleased to announce the latest assays from its Mt Venn copper-nickel-cobalt project in WA have confirmed the project is a significant discovery which remains open in all directions. The assays, which come from the RC and diamond drilling programs completed late last year, confirm extensive mineralisation within the Central zone at Mt Venn. They also confirm the presence of multiple, steeply dipping lenses over a 500m x 200m area, increasing the contained metal per vertical metre and development potential of the Central zone. In light of these results, infill drilling has been brought forward to better define these multiple mineralised lenses, with a 2,500m RC drilling program scheduled to start in two weeks. Given the combined strong copper-nickel-cobalt results, metallurgical testwork will commence next week following receipt of assays from hole 17MVDD002. The core is currently stored in a freezer to inhibit the oxidation of pyrrhotite prior to flotation and leach test work. Metal recovery and the production of copper concentrate and nickel and cobalt sulphate will be assed and then used to help target future exploration at Mt Venn. A Downhole EM (DHEM) survey will commence next week on all available holes from the December drilling program. The results will be used to define extensional targets at the margin of the Central zone and further along the western magnetic trend north and south of the Central zone. Importantly, mapping and surface sampling over the Eastern Mafic complex has identified a suite of mafic-ultramafic rocks that may represent a different intrusion phase to Mt Venn and is considered a target for nickel sulphide mineralisation. | |
