Partners Spider Resources (SPQ-A) and KWG Resources (KWG-T) have made a “somewhat unique” diamond discovery within exposed bedrock along the Trans-Canada Highway.
The partners recovered 64 mostly fragmented diamonds, including 8 macros, from 67.6 kg of rock taken from the side of Hwy. 17 in Ontario.
What makes the occurrence unique is its host — a mafic-to-ultramafic tuff horizon encased in Archean metavolcanics and metasediments. The highway outcrop has also been described by the Ontario Geological Survey as an intrusive breccia, or possibly a dyke of unknown affinity.
The so-called Sandor Diamond Occurence, which contains mostly clear, white fragmented stones, was discovered on a 45-sq.-km property optioned by Spider and KWG. The partners have now applied for a 204-sq.-km exploration licence (around and including the option property) from Algoma Central.
A program to locate and sample the vent that produced the diamond-bearing tuff will begin shortly.
