Measuring gold particle sizes tells us this is 0.012 grams gold nugget with length of about 2 mm

We measured the gold particle sizes so to easier estimate the outcomes during field assaying. With this big gold particles of 2-3 mm in its length, we know how many of such similar nuggets we need to one gram of gold. Estimates and learning of field assaying process is part of the program Start Your Own Gold Mine. Without practical experience on the field, person may be confused on how to estimate alluvial deposits.
