Goldgroup Mining (OTC Other: GGAZF; TSX: GGA) has completed 175 metres of underground tunnel development at Caballo Blanco, further confirming past drill results and the Company’s recently announced updated resource estimate. The tunnel at the La Paila Zone is being driven to collect bulk-sample material for ongoing metallurgical test work. The tunnelling also provides direct access to the mineralized zone allowing the Company to enhance its understanding of the geological and geotechnical characteristics of the mineralized silica body. Assay highlights from the tunnel include 34.2 metres of 0.77 g/t Au and 30.9 metres of 0.68 g/t Au from channel sampling in the main tunnel, and 42.2 metres of 0.46 g/t Au from sampling in the cross cut off the main tunnel. The results to date show good correlation between the channel sample results and blast material sample results.
