Due to unforeseen circumstances, Michele Coté, VP Exploration for Dalradian Resources Inc, will be giving this talk in place of Tim Warman. 


Ms. Coté has over 17 years of experience as an exploration geologist where 16 years were spent with MPH Consulting Ltd. Over the past few years, she was involved in the conceptual development and management of exploration programs. She has worked on numerous projects worldwide, from grassroots to advanced stage, for a variety of commodities including: gold, base metals, nickel, uranium, rare earth elements, diamond, and iron ore deposits. She has prepared or assisted with many independent, technical National Instrument 43-101 reports on mining properties. She possesses a wide range of technical and managerial skills related to mineral exploration including 3D modelling of mineral deposits, and interpretation and analysis of geological data using GIS software. Ms. Coté is a graduate of the University of Toronto (BSc and MSc) and a member of the Association of Professional Geoscientists of Ontario.



Abstract

Dalradian Resources’ Curraghinalt high grade gold deposit is located in the Sperrin Mountains of Northern Ireland about 100 km west of Belfast.  Hosted by Neoproterozoic metasedimentary rocks affected by the Caledonian Orogeny, the deposit consists of a series of structurally controlled, high-grade gold bearing quartz-carbonate veins.  The current 43-101 resource (Hennessey and Mukhopadhyay, 2012) includes 0.47 M oz at a grade of 13.0 g/t gold in the Measured and Indicated category and 2.23 M oz at a grade of 12.7 g/t  gold in the Inferred category.


The geological model underlying the current resource assumes a series of parallel, mineralized quartz-carbonate veins surrounded by barren country rock and undisturbed by post-mineral faulting. Dalradian geologists now recognize that this model is overly simplistic, with results from relogging and sampling over broader intervals on existing and historical core supporting 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 and individually-named D-veins) as well as numerous extension veinlets (C-veins) which surround the D-veins. Dalradian is currently undertaking a major reinterpretation of the deposit based on this new model, which is anchored on the named D-vein mineralization but incorporates the surrounding C-veins as well as accounting for obvious fault offsets. The potential for the C-veins to contribute additional ounces to the resource is not yet clear, although there have been some encouraging early results from the C-vein sampling program.


Currently, Dalradian is awaiting permission to conduct an underground exploration program which will aim to confirm continuity, grade and tonnage of the mineralized veins and collect a bulk sample metallurgical testing.



Dalradian Resources Inc. is a TSX-listed, Canadian based exploration company engaged in the acquisition, exploration and development of gold, base metals and other precious metals projects. With a European focus, our most advanced property is in Northern Ireland and focuses on and around the high-grade mesothermal gold deposit, Curraghinalt.
