Edward Peacock, P.G., P.E., Hydrogeologist / Principal

areas of specialization salar hydrogeology, groundwater supply development, fractured rock hydrogeology

Ed Peacock’s expertise in the hydrogeology of salars — the high, salt-encrusted basins found in the arid Altiplano regions of Chile, Perú, and Bolivia — has been a valuable asset to M&A since the early 1980s. Much of his work has focused on designing and overseeing field operations for exploration programs associated with planned and active mining operations, both in the U.S and in South America. He has extensive experience designing and overseeing drilling, construction, and testing operations for large-scale production wells, monitoring wells, and piezometers. In addition, Ed has used his modeling skills to evaluate the effects of groundwater development in both brackish and fresh water environments, as well as to assess water supply and dewatering requirements for mines. He has conducted numerous water supply and wellfield investigations in Northern Arizona.

Another area of Ed’s expertise is characterizing and quantifying brine resources that contain potentially economic quantities of lithium and potassium brine; he designed and managed field investigations for brine resource characterization in the Salar del Hombre Muerto in accordance with Canadian Securities Administrators National Instrument (NI) 43-101 and Australasian Joint Ore Reserves Committee (JORC) guidelines.
