Notable exploration on the Copper King Property began in the 1960’s with initial investigation of the copper potential of the DS and Sixty claim groups. Geological mapping, hand trenching and sampling, and an electromagnetic survey were completed over areas where disseminated and vein hosted copper±gold±silver was encountered.
In the mid-1970's, Canadian Superior and BP Minerals explored the Z claims for Sustut-style copper replacement in porous Takla Group tuffs. Geological mapping, geochemical sampling, induced polarization ("IP") and ground magnetic surveys were conducted over the claims and three short diamond drill holes completed in two areas.
Over 2,000 historic soil, talus, sediment and rock samples collected on the property have been digitized and outline several geochemically anomalous areas that warrant further exploration.
In 2015, PEMC completed a reconnaissance IP survey over areas of interest that identified two areas of anomalous chargeability for followup exploration. Rock chip sampling was completed in 2015 as well, expanding the footprint of anomalous copper rock geochemistry. In 2016 and 2017, PEMC completed two airborne magnetic surveys over the northeast portion of the property. This data has been integrated with the existing dataset to develop exploration targets for 2018.
