 Montana's motto, "Oro y Plata", Spanish for "Gold and Silver", recognizing the significant role of mining, was first adopted in 1865, when Montana was still a territory.A state seal with a miner's pick and shovel above the motto, surrounded by the mountains and the Great Falls of the Missouri River, was adopted during the first meeting of the territorial legislature in 1864–65.The design was only slightly modified after Montana became a state and adopted it as their Great Seal in 1893.
