Measuring gold particle sizes tells us this is 0.032 grams gold nugget

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. Without practical experience on-site, a person may be confused about how to estimate alluvial deposits
