Company Director / Senior Geologist


Dave graduated with a B.Sc. in Geology from Queens University Belfast in 1987. He obtained professional accreditation from the Institute of Geologists of Ireland in 1999 and a M.Sc. in Geotechnical Engineering, Design and Management from Nottingham Trent University in 2010.


Dave joined Rio Tinto in 1987 as a junior exploration geologist eventually assuming the role of Country Manager in 1995. He joined Noranda Exploration Ireland in 1996 as Senior Geologist, with responsibility for the implementation of their Irish carbonate hosted Zn / Pb programme, discovering the Pallasgreen Deposit

in 2002.


In partnership with Graham Reid, Dave founded BRG Ltd. in 2003 working on a wide range of projects in the exploration and mining, extraction, engineering and environmental industries. He was intimately involved in developing Pallasgreen from a minor exploration project to its current status as the second biggest Zn-Pb deposit in Ireland (in terms of contained metal) and he continues to be responsible for the management and implementation of the technical exploration programme at Pallasgreen project on behalf of the owner Glencore Zinc Ireland Ltd.




Graham Reid B.A., Eurgeol, P. Geo

Company Director / Senior Geophysicist


Graham graduated from Trinity College, Dublin with a BA (Hons) in Geology in 1979. He was accepted into the Institute of Geologists of Ireland as a professional member in 2003, and is currently serving as a committee member of the organisation.


After graduation Graham worked in the offshore oil exploration sector in areas including the North Sea and Canada. A move to mineral exploration geophysics in 1981 proved to be the catalyst for the rest of his career in which he has specialised in the design, implementation and interpretation of geophysical surveys – responsible for the implementation of cutting edge spatial and interpretative software as a GIS manager for a major mining company.


Graham founded BRG Ltd with Dave Blaney in 2003. The company has been involved in projects from Mineral Exploration to Geotechnical and Geophysical.
