Experience on a similar epithermal silver deposit in Mexico where 170 porosity measurements were made showed that the inclusion of the porosity information had little effect on the dry bulk density value, changing it by just one percent. It is therefore quite practical to use the average in vein SG value as a dry bulk density figure.
