The Altar District of Sonora, Mexico, stretches nearly 300 miles along the American border and approximately 200 miles along the Gulf coast. This particular district was noted for its rich placer deposits and gold ledges before the Spaniards ever settled the region. Several antiguas (Spanish mines) were later developed by the Europeans and were again being operated by the Americans as early as 1904.
