Report and Map
No Digital Data
Size 4 microfiche
Comment Diamond exploration included 2 ground magnetic surveys (192 line km in total) and a 2.7 line-km TEM survey. Two diamond drill holes totalling 206 m tested 2 geophysical anomalies. A diabase dyke and granite were intersected.

Activity Drilling
Comment Two NQ holes, totalling 206 m, were drilled by Midwest Drilling. The holes tested 2 separate targets identified by airborne and ground geophysics. No kimberlite was intersected in either target.

Activity Geophysics, Ground
Comment Two ground magnetometer surveys totalling 19.2 line km were completed over anomalies derived from airborne geophysical data. The survey areas were grid picketed and then traversed using Omni EDA IV magnetometers with a staff length of 2.5 m. Zonge Engineering and Research Organization collected nanoTEM survey data over one anomaly totalling 2.7 line km.

Activity Lab Work / Physical Properties
Comment Sample processing took place both on site at Lac de Gras and at Kennecott's heavy mineral laboratory in Thunder Bay, Ontario. Processing included desliming, classifying, magnetic separation and liquid separation. The magnetic, heavy mineral concentrate was sent for picking by Kennecott staff trained to recognize kimberlitic indicator minerals. Picked grains are studied in detail and those that merit were submitted to R.L. Barnett Geological Consulting in London, Ontario for electron microprobe analysis.

Activity Sampling
Comment Heavy mineral sample collection took place during the 1994 program and was based on results from the previous years of sampling on the claim blocks. Along with regional sampling, infill sampling over the northwestern part of the property reduced the spacing of the grid from 1000 m to 500 m. A total of 435 samples were collected.
