The two shiny metal blebs in the grey-blue lithology measure 3/4-1mm across. They are very distinct. Closer to the boundary between grey-blue and brown, there are a couple others but they're not as reflective and appear altered. I checked the brown matrix very carefully on both sides of the slice and did find one, fairly shiny metal bleb and a few, small altered bits of metal. In any case, the parts that have the strongest attraction to a magnet are highly altered, very dark veins that have a flow pattern in them.
