Measuring gold particle sizes tells us this is 0.032 grams gold nugget with length of about 3 mm

We measured gold particle sizes to more easily estimate outcomes during field assays.

With these large gold particles measuring 2-3 mm in length, we know that at least 30+ such particles are needed to reach one gram. Estimating and learning the process of field assaying is part of Start Your Own Gold Mine program. Without practical experience on-site, a person may be confused about how to estimate alluvial deposits.
