TORONTO, ONTARIO -- (Marketwired) -- 04/23/13 -- Dalradian Resources Inc. ("Dalradian" or the "Company") (TSX: DNA)(OTCQX: DRLDF) is pleased to provide an update on its on-going evaluation of a previously overlooked vein set (the "C-veins") at the Curraghinalt gold deposit in Northern Ireland. While work is ongoing to assess the potential impact of the C-veins on the existing resource, early results are very encouraging. A previously reported intercept in Hole 12-CT-170 of 0.76 metres grading 33.60 g/t of gold (PR Feb 13), has been expanded considerably to 7.21 metres grading 7.58 g/t of gold by incorporating the adjacent C-vein material.
"Although final results from this study are expected to take several more months, initial findings show the C-veins may have a positive influence on future resource estimates, at least in key portions of the deposit," says Patrick F.N. Anderson, Dalradian's CEO. "It is becoming apparent we need to think of the deposit in terms of broader mineralized zones rather than discrete narrow veins."
Until recently, the main resource veins (D-veins) at Curraghinalt have been thought of as discrete, individual units hosted in barren wall rock and historically the system was sampled on this basis, with little or no attention paid to the material outside of the main vein intercepts. The July 2012 Preliminary Economic Assessment, for instance, incorporates more than 2.5 million tons of material that falls outside of the main veins and was calculated to contain 0 g/t of gold.
Recent and ongoing work recognizes that this discrete single vein interpretation is overly simplistic. New results from sampling over broader intervals on existing and historical core support the idea that mineralization at Curraghinalt is hosted in a suite of sub-parallel Vein Zones comprising one or more shear veins (the historically recognized main veins) and Extension Veinlets (C-veins). By interpreting the mineralization into wider Vein Zones, the historical D-vein mineralization would still remain as the key or anchoring component, however, the wider zones of mineralization and structures will increase confidence in correlating mineralization on cross-section and from section to section. The result both advances our understanding of the geometry of the mineralization, and provides an improvement on the geological model previously utilized in resource estimation.
Ongoing logging and sampling of drillholes from key cross-sections, using both the current drill program and the historical core, will provide data to support a re-interpretation of the Vein Zones, leading to an updated resource estimate in Q4 of 2013. The updated resource will include approximately 35,000 m of new drilling and a portion of the historical core which was previously un-sampled.
Preliminary C-Vein Data
While the evaluation of the C-veins is expected to continue through to at least mid-2013, preliminary data from three holes shows that the C-veins are capable of contributing to wider mineralized intercepts than would previously have been defined by the main veins (D-veins) alone. The locations of the three holes are shown in Figure 1.
