SUMMARY
Enterprise Metals Limited (“Enterprise” or “the Company”, ASX: “ENT” ) is pleased to announce that exploration at its Doolgunna Project, 130km northeast of Meekatharra, has identified a 1,000 m long goldin-soil anomaly, now called Vulcan . Work recently completed at Vulcan and its immediate environs includes preliminary aircore drill testing of the soil anomaly, excavation and sampling of a costean, the completion of 140 hole aircore drilling program, and regional soil and rockchip sampling.
Vulcan Prospect
Following the discovery of visible gold in a shallow pit NE of the Doolgunna homestead, Enterprise completed two vertical aircore holes (DNAC069-070) drilled 40m apart either side of the pit. DNAC069 returned encouraging gold intervals of 3m @ 2.03 g/t Au from 1m and 11m @ 0.58 g/t Au from 92m to end of hole, (ENT:ASX announcements: 7[th] and 18[th] June 2012).
Based on these results and the lack outcrop, Enterprise excavated a costean to provide sub-surface geological/structural information as well as the character and setting of the visible gold. An estimated 500 tonnes of material was excavated from the costean and a total of 47 ounces of coarse gold was recovered with a metal detector, implying an undiluted grade approaching 0.1 ounce per tonne. This figure applies to the coarse “detectable“ gold portion only, and does not take into account the presence of any “fine” gold.
Four angled aircore drillholes (DNAC131-134) were completed targeting the down dip extension of a gossanous unit exposed in the costean. Due to hard ground and high water flows, hole DNAC132 failed to intersect the projected target zone but nonetheless intersected shallow mineralisation. (refer Figure 1 & Table 1 for hole locations) Anomalous results include:
Vulcan Prospect: Hole DNAC132 24m @ 0.19 g/t Au from 8m Incl. 4m @ 0.62 g/t Au from 16m Hole DNAC133 24m @ 1.67 g/t Au from 16m Incl. 8m @ 2.77 g/t Au from 40m Incl. 12m @ 1.38 g/t Au from 52m

Regional Aircore Drilling Program
A regional aircore drilling program comprising 134 holes for 7,790m, with holes at 200m spacings along lines 1km apart, was completed at the Doolgunna, see Figure 1. The drilling was targeting a supergene copper-gold enrichment “blanket ”, which may be developed below a “leached cap”, and above deeper primary sulphide copper-gold mineralisation within the Narracoota Formation volcanics. Anomalous results for gold were returned from the drilling as shown below.

All anomalous gold and copper results are summarised in Tables 2 & 3. Interestingly, coincident high values for gold and copper do not occur in the same hole, suggesting varying mobilities within the regolith profile for the two elements.

Proposed Drilling Program
At Vulcan, additional aircore drilling is planned over a 1,000m x 400m ENE trending area of nodular lateritic cover in the vicinity of the costean testing for repeat structures/mineralisation supported by anomalous gold results in soil samples.

A regional infill aircore drilling program comprising 250 holes for 10,000m has been designed in the general area. This drilling will initially focus on the area surrounding the Vulcan costean and anomalous soil sample results to define geological/geochemical targets for follow-up RC drill testing.
Follow-up of all anomalous gold and copper intersections from the previous regional aircore program is planned, along with infill lines targeting geochemical/structural trends between the original 1km spaced lines
