-
Initial RC drilling successfully completed at the Doolgunna Project. Sulphide mineralisation confirmed.
-
Hole DGRC007 at Doolgunna Prospect yields 8m @ 1.01% Cu from 144m. Broad zones of elevated copper intersected in Narracoota Volcanics. Management encouraged by these results and follow up programme being developed.
SUMMARY
Enterprise Metals Limited (“Enterprise” or “the Company”, ASX: “ENT” ) wishes to announce very encouraging results from an initial reverse circulation (“RC”) drilling programme at its Doolgunna Project located 100km NE of Meekatharra and 750km NNE of Perth.
At the Doolgunna Prospect just north east of Doolgunna Homestead, RC drillhole DGRC007 , drilled to test an IP anomaly in close proximity to the interpreted position of the Goodin Fault returned 8m @ 1.01% Cu, 1.6g/t Ag and 16.5 ppm Bi from 144m . The copper occurs as disseminated chalcocite hosted in fresh volcanics with associated quartz veining. DGRC007 is the first drill test of the prominent linear IP target located close to the Goodin Fault. The Company holds 12 strike kilometres of the Goodin Fault in the vicinity of the Doolgunna Prospect.
Management is developing a follow up programme to further test the extent of this sulphide mineralisation and to test other anomalies.

BACKGROUND
The drilling programme (31 holes for 5,049m spread over the three prospects) confirmed the presence of sulphide mineralisation. It successfully tested coincident IP and elevated coincident multi-element surface geochemical anomalies in Narracoota Formation volcanics and associated sediments adjacent to the Goodin Fault. The anomalies were considered to be indicative of the presence of sulphide mineralisation at depth, with potential for volcanogenic massive sulphide (VMS) mineralisation similar to Sandfire Resources NL’s De Grussa copper-gold deposit.
RC DRILLING RESULTS
Doolgunna Prospect
Ten RC holes for a total of 1,518 metres were drilled to test coincident IP and elevated coincident multi-element surface geochemical anomalies in Narracoota Formation volcanics and associated sediments adjacent to the Goodin Fault. (Refer Appendix 1)
Hole DGRC007 was drilled to test an IP anomaly at or close to the interpreted position of the Goodin Fault. The hole returned a highly significant intersection of 8m @ 1.01% Cu, 1.6g/t Ag and 16.5 ppm Bi from 144m. The copper occurs as disseminated chalcocite hosted in fresh volcanics with associated quartz veining, in close proximity to the interpreted position of the Goodin Fault.
The ENE trending Goodin Fault separates the magnetically complex Narracoota Volcanics (with interbedded sediments) to the north from the magnetically “quiet” Doolgunna Formation sediments to the south, and is potentially a pathway for the mobilisation and/or deposition of copper mineralisation. In the vicinity of the Doolgunna Prospect, the Company holds 12 strike kilometres of the Goodin Fault, and DGRC007 is the first hole to be drilled close to the Goodin Fault. (refer Figure 1)
The presence of elevated copper values within volcanics in holes DGRC004 and DGRC005 is considered significant because these values are three times greater than average crustal abundance for basalt (refer Table 1 below). In addition, these holes lie 2km SW along strike from hole NBRC010 drilled by Enterprise in late 2009, which intersected an 8m wide vein of chalcopyrite, pyrite and carbonate from 107m-115m. Within this vein, a 1 metre intersection assayed 0.9% Cu, 0.4 ppm Au, and 352 ppm Bi from 107m. The intersections in holes DGRC004, DGRC005 and NBRC010 have highlighted a sizable area within the volcanics, within which there is potential for higher grade mineralisation. (also refer Figure 1)

Ruby Well West Prospect
Eight RC holes for a total of 1,450 metres were drilled to test coincident IP and elevated coincident multi-element surface geochemical anomalies in Narracoota Formation volcanics and associated Karalundi Formation sediments adjacent to the Goodin Fault west of Ruby Well.
Ruby Well East Prospect
Thirteen RC holes for a total of 2,081 metres were drilled to test coincident IP and elevated coincident multi-element surface geochemical anomalies in Narracoota Formation volcanics and associated Karalundi Formation sediments adjacent to the Goodin Fault east of Ruby Well.
The RC drilling has adequately explained the targeted IP features, with several holes returning narrow intervals of sulphide mineralisation with elevated gold and copper values. The broader surface copper geochemical anomalism is thought to be a reflection of a general increase in the copper content of the volcanics in the vicinity of Ruby Well, i.e. a lithological association. A summary of significant drill results are in Table 2 and drill hole locations are shown in Figure 2.

COMMENT
The Company holds approximately 70 kilometres of the Goodin Fault zone, most of which is covered by varying thicknesses of younger transported sediments. In the immediate vicinity of the Doolgunna (Homestead) Prospect the Company holds approximately 12km of the Goodin Fault zone, and DGRC007 is the first hole to be drilled in close proximity to the Goodin Fault. The Company is therefore encouraged by this strong copper intersection from its initial RC drilling program.
The geological and 4m composite geochemical results are currently being assessed in relation to the IP geophysical data, and a comprehensive follow up program will flow from this and the results of re-assay of selected 1 metre samples.
