Project History

Commercial copper mineralization was initially discovered in Lisbon Valley and mined during the 1890’s at the Big Indian Mine.  Copper was mined on a small scale in Lisbon Valley until the 1960’s when modern exploration techniques were used to begin defining what is now the Centennial Pit which is being actively mined by the Company today.

The Lisbon Valley project was permitted in 1999 and Constellation Copper Corp, a Canadian company formerly publicly traded on the Toronto Stock Exchange, took ownership and capitalized the project between 1999 and 2004. Construction to build the surface infrastructure for the mine began in 2005.  The mine produced its fist copper cathode in 2006 and has continuously produced copper cathode since that time.

Constellation Copper Corp. was unsuccessful carrying out its business plan for the project and when copper prices sharply declined during 2008-09, mining was suspended and the parent company filed for receivership in Canada.  During 2009, a new private equity ownership group took control of the Lisbon Valley Mining Company through a Chapter 11 proceeding which resulted in a re-capitalized balance sheet supporting a modified turnaround business plan.

The Company’s turnaround effort was successfully carried out during 2009-2013 with an average monthly production increase of over 100% since 2009.
