Summary
Core Exploration (ASX: CXO) announces further excellent drilling results from recent RC drilling at its 100% owned Fitton project (EL 4569), which is located in a proven world-class uranium mining region, 500 kilometres north of Adelaide in South Australia.
Core’s drilling has hit exceptionally thick and high grade uranium intercepts which have continued to extend uranium mineralisation at Fitton (Table 1 & Figure 1-3).
Core’s exploration work and drilling at Fitton has now confirmed that:
-
uranium mineralisation outcrops
-
uranium mineralisation contains both thick and high grade intersections
-
uranium mineralisation extends to at least 150m downhole depth
-
mineralised structure is over 1km long and open in both directions
Core’s Fitton project is located in some of Australia’s premier uranium acreage (Figure 4), being just north of:
-
Beverley Mine (46Mlb U3O8 Resource 7.7Mt @ 0.27% (21,000T U3O8)
-
Beverly North Mine (8.8Mlb U3O8 Resource 2.2Mt @ 0.18% (4,000T U3O8
-
Four Mile project (71Mlb U3O8 Resource 9.8Mt @ 0.33% (32,000T U3O8)
-
Mt Gee (69Mlb U3O8 Resource 51.0 MT @ 0.06% (31,400T U3O8))
The remainder of the assays from the recently-completed Core Exploration drilling program are to be received toward the end of May 2013.
Results
Core’s recent RC drill program, comprising 23 holes for a total of 1836m, was focussed on the Scott Lee prospect and has extended the strike length and increased the depth of the mineralisation discovered at Scott Lee prospect by Core’s first drill program in November 2012 (Figure 1).
Drill Section 365575E
Section Drill holes SLRC017 and SLRC022 were drilled to test the depth potential of previous elevated uranium anomalism in SLRC003 identified in the first drilling program at Scott Lee.
SLRC017 and SLRC022 consistently intersected high grade results mineralisation including 6m @ 978 and 6m @ 1112ppm respectively within a broad 20m wide mineralised zone.

SLRC028 was drilled at 75 degrees to the south from the northern contact of the dolerite in order to test for mineralisation at depth down the schist whilst still crossing the unit to test each side of the contact (Figure 2).
60m thick drill intersection of uranium mineralisation grading @ 482ppm (0.05%) was hit by SLRC028 from 53m depth (Table 1).
Cross sectional view across the Scott Lee prospect illustrates that the schist is steeply dipping to the south to sub vertical with the uranium mineralisation more prevalent on the southern contact of the schist with the granites (Figure 2).
Drill Section 365500E
Section Drill holes SLRC021 was drilled to test the depth potential of previous elevated uranium anomalism in SLRC008, 11 and 12 identified in the first drilling at Scott Lee.
SLRC021 intersected broad uranium intervals of 21m @ 230ppm toward the southern contact of the schist from 110m (Table 1).
SLRC029 was drilled at 75 degrees to the south from the northern contact of the dolerite in order to test for mineralisation at depth down the schist whilst still crossing the unit to test each side of the contact.
75m thick drill intersections of uranium mineralisation grading 268ppm (0.03%) U3O8 were hit by SLRC029 from 82m depth. The hole ended in schist with elevated uranium levels.
Interpretation of the data is similar to section 365575 with the schist is steeply dipping to the south to sub vertical with the uranium mineralisation more prevalent on the southern contact of the schist with the granites (Figure 2).
Geology
Core has been comparing uranium mineralisation at Fitton with geological analogies locally and around the globe.
Uranium mineralisation at Scott Lee is associated with a mafic/dolerite system (reductant) within and adjacent to structures which are interpreted to penetrate both the uranium rich crystalline basement and nearby uncomfortably overlying sediments.
Notably, Scott Lee prospect is positioned only a few hundred metres below the major unconformity between the uranium rich Mesoproterozoic Mt Painter Inlier granites and the overlying upper Proterozoic Adelaidean sediments (Figure 3).

Unconformity related uranium systems in the Athabasca in Canada and McArthur Basin region in Australia are large in scale and drive and host large high grade uranium mineralisation. Uranium mineralisation in these unconformity related terrains is hosted in both the uranium rich basement and overlying sediments.
In addition to the work to targeting high grade mineralisation identified in and around Scott Lee, Core will expand its exploration to test the large package of Adelaidean rocks within a few hundred metres of Scott Lee.
