The 100% owned Lexington-Grenoble Deposit was developed as an underground copper-gold mine by Merit Mining Corp and saw a short period of production in 2008 by Merit Mining Corp., after which it ceased operation due to lack of funding indirectly related to the 2008 market crash. It has been kept on care and maintenance.

A total of 54,237 tonnes of ore were mined from the underground Lexington-Grenoble Mine by Merit Mining Corp. from April to  December 2008 and processed through the Greenwood gravity-flotation plant, producing 5,486 ounces gold, 3,247 ounces silver and 860,259 pounds of copper. Only a portion of the Lexington-Grenoble Deposit was mined in that episode.

The remaining resource estimate, based on a total of 232 drill holes, is given in the table below.

(1) Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues. It is noted that no specific issues have been identified as yet.
(2) The quantity and grade of reported Inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured mineral resource category.

(3) The mineral resources in this report were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council
