Jul 07, 2010 (A Wilson) - Large numbers of veins have been discovered and developed on the property. The most productive veins lie near the No. 3 and the No. 6 shafts with an area of unproductive veins in between. The veins near the No. 3 shaft strike either northeasterly or northwesterly. The veins near the No. 6 shaft strike north of west or northerly. All ore shoots occur within steep veins cutting relatively flat-lying Huronian Coleman Member siltstone and conglomerate lying beneath a Nipissing diabase sill.
