Doolgunna Base Metals Project
The Company has a strong land position centred approximately 110km northeast of Meekatharra and its tenements cover Palaeoproterozoic rocks affected by the Capricorn Orogen predominantly located within the Yerrida Basin. The primary target sought is one or more large mesothermal‐style gold stockwork systems and/or volcangenic massive sulphide systems. Sandfire Resources NL have reported that ground EM surveys identified two major sub-surface conductors in the Narracoota Volcanics, and subsequent drilling defined the DeGrussa mineral resource of 9.62Mt @ 5.5% copper, 1.8g/t gold and 14g/t silver.
Doolgunna Project Geology and Tenement Plan
The Company controls a significant strike length of the Goodin Fault, which separates the Narracoota Formation volcanics from the Doolgunna Formation sediments. The Goodin Fault has a strike length of approximately 100km, and is interpreted to be a major structure that may have provided conduits for mineralising fluids during collisional tectonics.
During 2009 Enterprise’s exploration and drilling program focussed on its granted tenements covering the Doolgunna Formation sediments of the Yerrida Basin. This was the first test by deep drilling of the Company’s alluvial gold and base metal targets along the 50km long magnetic trend termed the Southern Boundary Fault (“SBF”). Reverse circulation (“RC”) drill testing of various gold/copper and geophysical targets was completed in September/November 2009. A total of 40 holes were completed for 8,831 metres.
The best 2009 RC drilling results came from geochemical targets in the area around No. 2 Bore, which lies within the Narracoota Formation volcanics, adjacent to the Goodin Fault, approximately 6-9km NE of Doolgunna homestead. The southernmost drillhole (NBRC010) along a fence of holes testing a weak linear NW striking VTEM anomaly and a historical geochemical anomaly intersected narrow veins of chalcopyrite, pyrite and carbonate from 107m-115m, which included 1m @ 0.4g/t Au and 0.9% Cu from 114m.
In 2010, the Company commenced infill soil geochemical along the Goodin Fault where it contacts the Narracoota Volcanics. Although this work is incomplete, a number of significant base metal anomalies have been identified for further infill.
Upon completion of the soil programs, RAB and RC drilling programs will be implemented.
