ABSTRACT:Helix Resources Limited (ASX:HLX) (Helix or the Company) is pleased to report an interim maiden Indicated and Inferred Mineral Resource estimate for the Central Zone portion of the Collerina Copper Deposit, located in the Cobar Region of Central NSW. High grade copper from near surface at Collerina provides scope for potentially advantageous development optionality and the Project is well located in a region with increasing development and exploration activity. The interim Indicated and Inferred Mineral Resource estimate is 2.02 million tonnes grading 2.03% Copper, 0.1g/t Au and includes a high-grade massive sulphide component of 1.4 million tonnes grading 2.6% Copper, 0.2g/t Au (see table below). The mineral resource has been reported by an independent resource specialist, PayneGeo. This Resource announcement has been delayed from earlier expectations due to a substantial reinterpretation of the mineral systems localised geometry, particularly in the deeper parts of the system, and with several delays in drilling. The new interpretation will be a critical part in the planning for future drilling to expand on the Resource estimate. The review has established a robust and refined interpretation of the broader Collerina copper system. It provides clear vectors to expand the known copper mineralisation envelope, well beyond the current drill pattern. The challenge of drill density in the resource modelling is illustrated in the photographs of Collerina drill core in Figure 2, which is a fractal representation of the larger scale. In the absence of close-spaced drill density, zones of structural thickening (and generally increased grade) are insufficiently represented in the resource database and shape.
