Beautiful Miners Pickaxe found in our cellar, 1840s

This was leaning against the wall in our cellar dirt floor, house was built 1801, My wife's family moved in after Civil war 1870s, Charles Pickett married a famous women who had a baby. He and his brother traveled in 1840 to the California gold rush, came back to Salem Ma for the war. This pickaxe is from these years, very heavy 12 lbs, and i wonder if i can find out which years actually this came from? would he bring back across the USA from Cal to Mass.
