Major 10,000m infill aircore drilling at Vulcan and surrounding anomalous drill targets to commence late September.
SUMMARY
Enterprise Metals Limited (“Enterprise” or “the Company”, ASX: “ENT” ) is pleased to announce the results of detailed soil sampling which have defined a coherent and partly coincident gold/copper soil anomaly over the Vulcan Prospect, with one rock chip assaying 810g/t gold with associated high copper, silver and bismuth. In addition, fire assay results of 1m re-splits from the recently completed aircore drilling program have confirmed previous assays of 4m composites.
The Company’s Chairman, Dr Jingbin Wang, commented: “The recognition of coincident copper/gold anomalism over a significant area at Vulcan, coupled with a VMS multi-element soil anomaly on the eastern edge of Vulcan which is still open to the east, indicates potential for a base metal mineralised system at depth.
We are dealing with a very deep zone of oxidation, and before we drill deeply, we need to further define our target area with aircore drilling. An aircore drill program will commence in September to better define the Vulcan anomaly and test other nearby copper/gold anomalies in the oxide zone, in preparation for deep RC drill testing of these targets”.
Vulcan Prospect
Results from the Company’s ongoing soil sampling program over Vulcan have defined a 1,500m long NE trending zone of copper, with anomalous gold. A new base metal multi-element association comprising gold, silver, arsenic, lead, zinc, molybdenum, antimony (Sb) and cadmium has been identified on the open, eastern margin of Vulcan. Further soil sampling is in progress.

A rock chip sample with visible gold, located in the general vicinity of the Vulcan soil anomaly, returned 810g/t Au, 0.1% Cu, 18.3g/t Ag, 1.0% Bi, 132ppm Mo and 2.7ppm Sb , which supports the base metal prospectivity of the area. This gold/base metal association is similar to the VMS pathfinder elements reported from the DeGrussa deposit 13km to the NE. Both DeGrussa and Vulcan are hosted by the Narracoota Formation volcanics, adjacent to major regional faults.
Figure 1 shows the location of the copper/gold soil anomalism, current aircore drill hole locations, and the 810g/t Au rockchip sample (Refer Tables 1-3)

- Fire Assay of Aircore 1m Re Split Samples Confirms Strong Oxide Gold Mineralisation
All 4m composite samples with values >0.1g/t Au from the June-July aircore drilling program were re-sampled at 1m intervals and analysed by the fire assay method. Table 3 summarises the best results, while the drill holes are located on Figure 1.
The widths and grades of these intersections are considered highly encouraging given that they are from first pass, broad spaced drill holes. All of these oxide intersections remain essentially “open” in most directions and follow-up drill testing to define their relationship with primary sulphide mineralisation is required.

New Vulcan Drilling Program to commence in September
A 260 hole aircore drilling program will commence late September at the Vulcan prospect and surrounding area testing previous gold intersections and multi-element geochemical anomalies.
This program is designed to enhance Enterprise’s understanding of both the bedrock geology and the distribution of gold, copper and pathfinder elements in the regolith, with the ultimate aim of delineating VMS and gold mineralisation in the primary (fresh rock) zone.
Regional Drilling Program planned for October
A regional aircore drilling program comprising 250 holes for 10,000m along 12 traverses has also been designed and submitted for approval to the DMP. This drilling will focus on the copper/gold mineralisation associated with the Southern Boundary Fault and Doolgunna Formation.
The traverses will test a combination of geochemical and geophysical targets over a 60km strike length located southwest of Vulcan, and drilling is scheduled for October-November.
