Examining the physical properties of the suspected silver ore can lead to discerning the true identity of the mineral. Silver ore is heavy, malleable and sectile. In other words, the mineral can be forced out of its original shape and cut into pieces. Silver ore is very rarely found isolated in individual nuggets of pure silver.
