In granite pegmatite.
"The dyke is exposed on the north side of a hill on the east side of Blackstone Lake. It is about 18 m wide and is exposed for a length of 21 m. It was opened by a few small pits in 1922 by Robinson and McQuire for radioactive minerals."
Visited the property on Oct 10,2009 and discovered that the pits are now on private property (posted No Trespassing) and have been rehabilitated ( pits filled in with earth ). Someone built a cottage about 100m from the site and the road to the cottage passes within metres of the site. All that remains is a small pile of overgrown pegmatite fragments (quartz,mica,&feldspar) down slope.
