Bundle Description

All pXRF analyses were acquired using a Thermo Scientific Niton XL3t GOLDD portable XRF spectrometer (serial number 37005) on the surface of cut exploration diamond drill core. The spectrometer is equipped with a Cygnet 50 kV, 2 watt, Ag Anode X-ray tube and a XL3 silicon drift detector and was mounted in a Thermo Scientific mobile test stand at the Agnico Eagle Mines Meliadine exploration camp. Analyses were repeated in ‘soil’ (optimized for element concentrations <1 wt. %, i.e., minor and trace elements) and ‘mining’ (optimized for concentrations >1 wt. %, i.e., major elements) modes for each sample spot using a 60 s dwell times for each of the Main, Low and High filters (total analysis time = 180 s; see Knight et al., 2013, GSC OF 7358 for further analytical details).

These data are published in GSC Open File 7711.
