ASX ANNOUNCEMENT
ASX : CXO
4[th] December 2013
IP DRILL TARGETS FOUND UNDER HIGH GRADE SILVER
BLUEYS, NT
HIGHLIGHTS
-
IP drill targets identified below very high levels of silver at surface at Blueys and Inkheart Prospects
-
Confirmed drill targets show strong correlation between:
-
High-grade silver mineralisation at surface
-
High silver, copper and lead in soils at surface
-
Chargeable IP anomalies at depth
-
Targets now ready for RC Drilling planned for early 2014
Core Exploration Ltd.’s (ASX: CXO) recent Induced Polarisation (IP) geophysical survey has identified highly prospective drill targets at both the Blueys and Inkheart Prospects within the Company’s larger Albarta Project in the Northern Territory.
Core believes that these new IP targets in combination with high silver in soil and high-grade rock chip results are a very strong indicator of significant mineralisation at depth (Figures 2- 6). In anticipation of these positive results, Core has already commenced processes to enable drilling at Blueys and Inkheart as early as possible in 2014.
The bulk of the chargeable IP targets appear to be between 75-150m depth and are underlying silver (± copper ± lead) soil anomalism and mineralised rocks at surface (Figures 2-6). Drilling has never been conducted to these depths at Blueys so these targets are untested.
Previous mapping and rock chip sampling at Blueys has identified a broad zone of pervasive stock-work veining associated with malachite and azurite (copper) and argentiferous galena (lead/silver) minerals at surface. Rock chip samples from sampling at Blueys graded up to 4,065 g/t silver (Ag), 8% copper (Cu) and 25% Lead (Pb) (Figure 1 and Table 1).
Core’s recent soil results have also defined an exceptionally high core of silver anomalism at Blueys and Inkheart Prospects (Figure 1).

Soils at Blueys have defined a sizeable silver footprint of 700m x 400m with a peak of 25,250ppb silver. Very high silver in soils has also been defined at Inkheart Prospect over a distance of 2,000m with a peak of 19,552ppb Ag. These very high values are spectacular when considering that 100ppb is commonly regarded as anomalous silver in soils (Figure 1).
Core’s recent soil results have also confirmed a strong correlation between lead and copper in soils and the high silver anomalism that characterise both the Blueys and Inkheart Prospects.
The Blueys and Inkheart Prospects (EL 28136) are 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 (+ silver) occurrences. Core is currently earning a 51% interest in EL 28136 and has also has the right to purchase a 100% interest in the tenement at any stage.
Induced Polarisation (IP)
Induced Polarisation (IP) is a geophysical technique that involves transmitting electrical current into the ground. From measurements of the induced potential field the chargeability and resistivity of the subsurface rocks can be calculated. In comparison to Electro-Magnetics (EM), IP measures a different physical property of the rock.
In this instance, Core is utilising IP to measure the potential level of sulphides in the rock.
Next Steps
Core is currently planning to commence an RC drilling program as early as possible in 2014, subject to having required approvals in hand. To this effect the company has commenced the process of securing land access approvals to enable the drilling program to proceed.
Core is currently undertaking further modelling of the IP data and will update the market regarding the details of the upcoming drill program in due course. The depth, dimension and intensity of the chargeable features will be better defined through further processing of the data.

| done by | 1983. Two phases of relatively shallow drilling has been undertaken at the | ||
| other parties | prospect since then. An airtrack percussion 9 hole for 178m program was | ||
| undertaken by Petrocarb Exploration in 1986. A reverse circulation drilling | |||

|
| Drill hole Information A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collaro elevation or RL (Reduced Level – elevation above sea level inmetres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception deptho hole length. If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. N/A |
|
| Data aggregation methods In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated. N/A |
|
| Relationship between mineralisatio n widths and intercept lengths These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). As the geochemical results thus far collected by Core Exploration are from surface, Any potential depths of mineralisation or orientations can only be inferred from geological observations on the surface and hence are speculative in nature. |

| intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
|
| Balanced reporting Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. Displaying details of all rock chips collected in parts of the Blueys prospect is impractical due to the scale of sampling, as such figure 1 displays the geographic locations of all samples that are listed in Table 1, the highlighted samples are those samples which had >100ppm Ag, all sample coordinates and assays are provided in the Table 1. |
|
| Other substantive exploration data Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. See release details |
|
| Further work The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.
