Please read these notes before sending your samples to GSS:
1) Please break samples into small fist-sized chunks prior to shipping – best done on the outcrop to minimize contamination.
2) For most lithologies, please send no more than 1-3 kg of material per sample. If low yields are expected, please inquire about the additional cost for processing additional material.
3) Generally, GSS will crush, sieve, and wash all material provided for each sample. However, the amount of washed material processed through both heavy liquids (LMT and DIM) and three magnetic separations will depend on indicated apatite and zircon yields. Regular price includes processing of up to 400 g of material through the first heavy liquid (LMT).
4) We do not process the entire sample if adequate apatite and zircon yields are indicated. Please note that the cost for each separation will depend on the size of each sample provided. If a client wishes for the entire sample to be separated, independent of yields, please inquire about the additional cost for this service.
5) If you want to keep a hand sample or a chunk for a thin section, please reserve those pieces before sending the sample(s) to GSS.
6) As part of the per-sample rates, GSS returns all mineral concentrates and magnetic fractions.
7) Unless GSS is asked to also return any excess material, GSS will retain excess material for a period of 90 days after completion of the project and shipping of the mineral separates – after which the excess material will be discarded. This excess material can be returned if requested for an additional shipping/handling fee: Domestic: $30/box; International: actual cost.

Pack Your Samples Carefully!
When packing your samples to send them to GSS, ensure that when you pick up the box and shake it, nothing is loose and able to move around in the box.
You do NOT want your sample boxes to arrive looking like the ones shown below...
