The specimen is from Ben Grguric. As he describes on his label: Cross-fibre vein of iowaite lizardite altered dunite with blebs of pentlandite. You will note his specimen on Mindat also states the rock matrix is altered to Dunite and the Iowaite is altering to pyroaurite. Note also the Woodalite crystal grains to 1mm in the matrix. The Iowatie "vein" is 5mm across.
