Representative Projects

Mining, Tailings and Water Management

Endeavour Silver Corp / AMEC Environment and Infrastructure

Bolanitos Silver Mine, Guanacevi Silver Mine, El Cubo Silver Mine, States of Durango & Guanajuato, Mexico

2011 to Present. Associate Engineer and Project Manager. These three silver mines in Mexico are typical of Mexico’s rich history of silver mining. There are numerous underground workings for ore production that all report to a single processing location which generates raw tailings in ever increasing production rates. The tailings facilities are drilled and sampled for geotechnical data and modeled and studied to generate stability quantification that allows AMEC to consult the mine operators and owners through the important process of properly stored tailings, reagent contamination containment, wastewater and stormwater management, solution capture and storage, and fresh water recovery for system replacement. Included in these projects are wet and dry storage of tailings, filter press plants, cyanide neutralization process, stormwater capture, mine reclamation and closure costing and reporting, permitting support, mine expansion value engineering, and overall tailings process management.

Great Panther Silver / AMEC Environment and Infrastructure

Cata Silver Mine, Topia Silver Mine, States of Durango & Guanajuato, Mexico

2012 to Present. Associate Engineer and Project Manager. These two silver mines in Mexico are also typical silver producing mines with tailings management and water resources management challenges. The Cata Silver Mine is part of the Guanajuato Mine Complex which for 250 years produced two-thirds of the world’s silver. These historic and large silver mine facilities have proximity to urban development and thus are critical to achieve a very high level of stability and runoff output quality. AMEC E&I provides annual assessments for SEMARNAT, Mexico’s environmental protection entity, and ongoing stormwater and solution capture assessments to facilitate the high Canadian standards for environmental care.
