2 Useful information with respect to mineral processing of DeLamar Area gold-silver mineralization by milling and subsequent cyanide leaching is derived from mill production records from the historical open-pit mining operations from 1977 through to the end of 1992. All ore during this time period was mined from the DeLamar Area and was processed by crushing, grinding,

exploration and heap leach operations commenced in the 1980's and Perseverance produced a total of 7.5 t of gold from these operations. By December 2001 open pit oxide ore reserves were exhausted and mining operations ceased. During 2001 and 2002 the main activities were drilling of the primary deposits and leaching of existing heap leach pads. 1
