Very high grades of graded up to 4,065 g/t silver (=4kg/t) (Ag), 8% copper (Cu) and 25% lead (Pb) have been identified in surface rock-chip sampling at the Inkheart/Blueys Prospect within the Company’s Albarta Project in the Northern Territory.
Soils have also 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.
Mapping at Inkheart/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.
Core’s first discovered high grade silver, lead and zinc mineralisation at the Inkheart Silver Prospect, which is defined by a 2km long silver in soil anomaly to the north east of the Blueys Prospect .
The Inkheart Prospect had not been drill tested prior to this drill program.
Drillhole IKRC002 hit high grade silver lead and zinc mineralisation at 112m down hole with a 4m intercept @ 195g/t Ag, 5.24% Pb and 2.49% Zn from 111m including 1m @ 354g/t Ag, 11.13% Pb and 6.51% Zn. This higher grade mineralisation is within a broad lower grade halo of 36m @ 29g/t Ag from 90m down hole drilling in 2014 at Inkheart/Blueys has intersected broad zones of silver and lead mineralisation including high grades.
The mineralised zone at Inkheart containing wide and high-grade intersections has now been intercepted consistently for at least 500m along strike within the targeted Bitter Springs Formation.
The mineralised zones at Inkheart are open to the north east, at depth and potentially to the south west. Core believes there is potential for further mineralisation over a much larger area within the target Bitter Springs Formation geology. This reinforces the tenement wide and regional potential of the Bitter Springs Formation for the discovery of economic precious and base-metal deposits.
