Big River Gold Limited announced that drilling is underway at the Borborema Gold Project to test depth and high grade shoot extensions which can be incorporated into mine planning for expanded production scenarios. Big River's objective is to better define the width and grade of the resource at depth for improved mine planning and investigation of expanded production scenarios for the Borborema project. In addition there are significant previously reported high grade intercepts that appear part of a southerly plunging shoot development and warrant follow up. These intercepts include 50m at 4.95g/t Au (CRDD-138) and 47m at 2.31 g/t Au (incl 15m at 3.61g/t Au) in CRDD -134. Big River has planned approximately 5,000 meters in the first stage diamond drilling program initially targeting the high grade down plunge and below pit extensions. This comprises: Step out drilling 100m down plunge from prior intercepts will test continuous higher-grade zones. Pit optimisation work is limited to the current drilling and Big River is confident this current drilling will identify and extend mineralisation down dip >100m over 1.2km strike, and Additional infill drilling will be planned once this initial stage is completed.
