ASX ANNOUNCEMENT
ASX : CXO
23[rd] April 2013
2.2 kg/t silver and 10% copper assays from rock-chip sampling at Blueys Prospect, NT
HIGHLIGHTS
-
2.2kg/t (2,200 g/t) silver and 10% copper in re-assay results of rockchip sampling from Core’s Blueys Prospect, Northern Territory
-
Soil surveys are currently underway at Blueys to prioritise targets for drilling
Very high grades of 2.2kg/t (2,200g/t) silver and 10% copper at surface have been confirmed by results from the re-assay of samples from Core Exploration Ltd’s (ASX:CXO) first reconnaissance mapping and surface rock-chip sampling at the Blueys Prospect within the Company’s Albarta Project in the Northern Territory.
The samples taken by Core from Blueys are described as intensely altered, granitic textured host rock with secondary copper mineral veins containing malachite and azurite. The assays are tabled below (Table 1):

Mineralisation sampled by Core appears to occur in the basement in brecciated and carbonate-silica altered granite. Core therefore believes that Bluey’s prospect is also related to Meso-Proterozoic basement as opposed to the previous focus in the overlying NeoProterozoic (younger) Bitter Springs Formation (Figure 1). This greatly increases the prospectivity for a much larger scale mineralising system at Blueys.
The orientation of the mineralised structures has yet to be well defined at Blueys and mineralisation seems to be open in most directions except to the south east. Isolated

gossanous outcrops occur in the area surrounding Blueys and may be related to the same mineralising event.
The Blueys Prospect is within Core’s Albarta Project that covers over 2,000km[2] of the newly recognised, highly prospective IOCG Aileron Province, 100km NE of Alice Springs in the NT. Core’s tenements include a number of significant copper, gold, silver, uranium and rare earth element (REE) mineral occurrences (Figure 2).
Blueys Prospect background
A limited amount of shallow drilling has been conducted previously at Blueys (Figure 1). In 1986, a short drilling program comprising 9 holes for a total of 178m, came up with a best result of 10m at 14g/t Ag and 0.2% Cu (BSA02 0-10m).
A RC drill program comprising 11 shallow vertical holes for a total of 433m (max depth 52m) was completed by Silver Standard in 2001 (Figure 1). Very high levels of silver, lead and copper were intersected in most holes. The best drill intersections are summarised below :
| Hole | from(m) | to(m) | interval(m) | Ag (g/t) | Pb(ppm) | Cu(ppm) |
|---|---|---|---|---|---|---|
| BS01 | 13 | 14 | 1 | 22 | 5200 | 135 |

Next Steps
Core currently has a regional soil sampling program underway on EL 28136 with more detailed infill sampling planned around the Blueys Prospect. This exploration work as well as additional mapping and sampling will be utilised to prioritise drill target for Core’s first drill program on the Albarta Project in 2013.
