Geological and geochemical investigations undertaken in the vicinity of the historic Mucatoona copper occurrence indicate that the Angepena ?diapiric breccia zones have no potential for hosting economic mineralisation. There is only a marginal association of malachite/azurite/limonite mineralisation with the perimeter of the North Breccia Zone, in a situation which could also apply to the three other smaller breccia bodies nearby, and this small occurrence is believed to arise from the passage of hypogene copper-bearing fluids, with metal precipitation occurring in the wall and roof rocks. Two prospects (Mucatoona and the 'Angepena gossan') were RAB drilled for copper and gold respectively, with disappointing results. 6 holes for a total penetration of 750 feet were drilled to test the oxidised white shale, Wearing Dolomite Member lode rocks under cover at Mucatoona. 8 holes for 1094 feet were drilled to test for an inferred auriferous pyritic bedded ironstone unit that might underlie the 20 foot wide and 26,000 foot long gossanous zone that outcrops immediately upslope from the Angepena alluvial gold diggings.
