They are talking about microscopic black holes. These things will have a radius of 1nm ( I.e. you'd need a microscope to see the track through a rock ).
Something this size would have the mass of a very large mountain ( 10^15kg) , and take 10^20 years ( universe is 10^10 years old ) to evaporate.

I'm skeptical because if these things are kicking about in any appreciable numbers, they would fall into stars and completely eat them.
Still worth looking for, would be a simple job for a team of students.
