High grade silver discovered in new western-zone at Blueys, NT
HIGHLIGHTS
-
1,533g/t (1.5 kilogram per tonne) silver discovered 500m west of previous high grade samples
-
Results significantly increase the scale of high-grade mineralisation
-
IP geophysical survey to start this week
New high-grade silver mineralisation has been discovered by Core Exploration Ltd(ASX: CXO) at the recently recognised western zone at Blueys Prospect. Core’s latest results have significantly increased the potential scale of the mineralised system at Blueys Prospect within the Company’s larger Albarta Project in the Northern Territory.
The new results and mapping have expanded the extent of mineralised outcrop at Blueys by 500m toward the western contact between the Bitter Springs Formation host rock and amphibolites in the basement rocks (Figure 3).
Core’s recent soil survey highlighted this area as having highly anomalous silver and lead in soils, which then led to Core’s discovery of this additional high-grade silver at surface in the new western zone at Blueys (Figure 2).
The western side of Blueys has not been tested by previous exploration, which was focused on the eastern flank.
The highest grade silver results have come from surface rock-chip sampling of a red-purple fine grained siliceous unit which is near the contact with the basement amphibolite (Figure 1 & Table 1). This hydrothermally altered unit appears to overly the carbonate rocks hosting mineralisation at central and western zones at Blueys.
The mineralised siliceous unit on the western end of Blueys is highly prospective due to the presence of mineralised surface rocks within a broad and coincident silver, lead and copper soil anomaly, as well as the evidence for intense fluid flow (stock work veining) at the contact between the Bitter Springs Formation and the basement.

Mapping and rock chip sampling at eastern Blueys has identified a broad zone of pervasive stock-work veining associated with malachite and azurite (copper) and galena (lead/silver) minerals at surface.
The Blueys and Inkheart Prospects 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 (Figure 4).

Next Steps
An Induced Polarisation (IP) geophysical survey is scheduled to commence this week to map mineralisation at depth and define drill targets at Blueys and Inkheart Prospects.
In parallel with Core’s field work, the Company has also commenced land access procedures to enable the required approvals for drilling at Blueys and Inkheart.
