SIGNIFICANT COPPER – GOLD DISCOVERY CONFIRMED AT PASKEVILLE, SA.
Highlights
-
Un-bottomed intersection of 42 metres at 1.10% copper and 0.11g/t gold in drillhole PAC006, including 5 metres at 2.93% copper and 9 metres at 1.69% copper , confirms significant discovery at Paskeville Prospect, SA. Other new hits include:
-
7 metres at 1.16% copper and 0.13g/t gold in PAC005;
-
7 metres at 1.07% copper in PAC009;
-
7 metres at 1.40% copper and 0.26g/t gold in PAC016; and
-
5 metres at 1.05% copper in PAC024.
-
These results follow the 19 March announcement of intersections of 10 metres at 1.06% copper and 9 metres at 1.27% copper in the first hole drilled at Paskeville.
-
Significant silver present with best intersection of 10m at 26.6g/t silver in PAC009.
-
Compelling targets exist along strike from the area drilled to date, and on the broader Paskeville geochemical anomaly which is much larger than the area drilled so far. In light of these excellent results the company’s Board has approved additional funding to immediately commence follow-up drilling.

Background
The Moonta Project falls towards the southern end of the Olympic Copper Gold Province on the Yorke Peninsula of South Australia. The majority of the project tenement is 100% owned by Adelaide Resources Limited, while in the Moonta Porphyry Joint Venture the company holds 90% equity with Breakaway Resources holding the remaining 10% (Figure 1).
On 19 March 2012, Adelaide Resources Limited announced that its very first drill hole completed at the large, previously undrilled, Paskeville geochemical target had intersected two zones of significant copper mineralisation. The Paskeville Prospect falls in the east of the Moonta Project tenement in an area wholly owned by Adelaide Resources. The first drillhole, PAC001, returned 10 metres at 1.06% copper from 11 metres downhole, and a second zone assaying 9 metres at 1.27% copper from 58 metres down hole.
New Results
Following PAC001, a further 23 aircore holes and a single diamond drill hole have been completed at Paskeville. Figure 2 presents a plan of the small part of the Paskeville Prospect drilled so far, and shows the location of the drillhole collars which are located on six, 50-metre spaced, northeast oriented drill traverses.
The basement host rocks to mineralisation are buried beneath several metres of unconsolidated sand and clay cover. Weathered bedrock comprises a clay rich saprolite which persists to various depths below the cover sediments, while unweathered bedrock is a fine grained metasediment that shows evidence of hydrothermal alteration.

In many drillholes copper minerals, including malachite, azurite, native copper and chalcopyrite, were visually observed during geological logging. Assaying of the samples collected from the 23 aircore holes is now complete and confirms that copper mineralisation is widespread and developed over widths and grades that indicate the Paskeville Prospect is a significant discovery. A list of drill intersections is presented in Table 1, while Figure 3 presents a cross section along one of the drill traverses completed at Paskeville. Logging and sampling of the single diamond drillhole, PASDD001, is still underway with assays anticipated in the coming weeks.
Hole PAC006 (Figures 2 and 3) has returned a highly significant intersection. PAC006 intersected 42 metres at 1.10% copper and 0.11g/t gold commencing from 56 metres downhole. The intersection is un-bottomed with the hole remaining in mineralisation at its final depth at 98 metres. Sub-zones of higher grade mineralisation in PAC006 include 5 metres at 2.93% copper and 0.21g/t gold commencing from 62 metres downhole, and 9 metres at 1.69% copper and 0.14g/t gold from 78 metres. Metal grades in individual 1-metre samples from PAC006 range up to 8.56% copper and 0.60g/t gold.
Further intersections of note occur in holes located on four of the five other drill traverses at the prospect, and include 7 metres at 1.16% copper from 58 metres in PAC005; 7 metres at 1.07% copper from 22 metres in PAC009; 7 metres at 1.40% copper from 49 metres in PAC016; and 5 metres at 1.05% copper from 38 metres in PAC024.

Higher grade zones of copper are generally contained within broad zones of lower grade mineralisation. Examples of these broader zones include 32 metres at 0.51% Cu from 32 metres downhole in PAC024, 45 metres at 0.45% Cu from 35 metres in PAC017, 55 metres at 0.39% Cu from 30 metres in PAC005, and 23 metres at 0.48% Cu from 22 metres in PAC009.
Several holes finished in copper mineralisation confirming that the mineralisation remains open at depth in addition to remaining open along strike in both directions.
Anomalous to low grade gold is commonly present with the best 1-metre sample assaying 0.82g/t gold in drillhole PAC016. Silver is commonly associated with copper mineralisation and in places reaches potentially significant concentrations, with Table 2 presenting silver intersections of note. Along with copper, gold and silver, the mineralisation has elevated rare earth elements (lanthanum and cerium), completing a geochemical fingerprint that is indicative of a geological affiliation to the highly pedigreed iron-oxide copper-gold class of deposits.

Discussion
Copper mineralisation in the area of the Paskeville Prospect tested to date is widespread and achieves attractive grades and downhole widths in several holes, most notably in the 42 metre intersection at 1.10% copper returned in hole PAC006.
Additional exploration drilling is required before a confident interpretation of the distribution of mineralisation can be made, however the early results suggest the mineralised system in the area drilled possibly has a northwest trend, essentially orthogonal to the current drill traverse direction.

The mineralised zone remains open along its possible strike to both the northwest and southeast, and the continuation of mineralisation to the bottom of several holes confirms it remains open at depth. Compelling targets exist in each of these areas and clearly warrant further exploratory drilling.
Most significantly, the area drilled to date at Paskeville is only a very small part of the broader surface geochemical feature that defines the prospect. Calcrete anomalism occurs over an area approximately 4.5 kilometres by 2.0 kilometres in size, with drilling to date confined to a sub-area of just 250 metres by 200 metres (Figure 4).

Other than an unassayed hole drilled in 1975, there is no recorded historical drilling in the broader Paskeville anomaly and exploration targeting the full extent of the geochemical feature is also clearly warranted.
In light of these exciting results, the company’s Board of Directors has approved further funding to complete immediate follow-up drilling at Paskeville. The aircore drill rig has been secured and follow-up drilling is anticipated to be underway by the end of this week. Initial holes will be sited to locate extensions to the already defined mineralisation, while first pass drilling designed to evaluate the broader Paskeville geochemical anomaly is also planned.
