(2) The nature, extent, and cost of the work performed;

(3) The basic findings of the surveys; and

(4) The name, address, and professional background of persons conducting the work and analyzing the data.

(c) You may not count these surveys as assessment work for more than 2 consecutive years or for more than a total of 5 years on any one mining claim.

(d) No survey may repeat any previous survey of the same claim and still qualify as assessment work.
