Procedure 1:
Sample Preparation
Purpose:
Samples are prepped for analytical work.
Description:
All samples are dried, crushed and ground. Assays are performed on <200 mesh (-75um) material and reported on a dry basis. Approximate 30 gram sample size required of mineralized geological rock chips or grains. Samples must be submitted in provided envelopes.
10 sample minimum for all procedures.

Procedure 2:
Qualitative Economic Scan
Purpose:
Geological sample economic survey to determine if further assay work is warranted.
Description:
All samples are examined semi-quantitatively for La-Lu, Y, Zr, Hf, Nb, Ta, W, Sn to determine if concentrations are significantly above crustal abundance and further analytical work is justified.
Note:
All unknown samples receive procedures 1 and 2, unless otherwise discussed with GTA staff.
