New Mexico Mineral Symposium — Abstracts

The occurrence of tungsten-bearing minerals in the Ortiz area has been recognized for many years. During the 1950's, fruitless efforts were undertaken to develop an economic scheelite concentrate from the very ores that are successfully mined today for gold. While several tungsten minerals have been found in the area, scheelite is by far the most abundant and the only one to produce collector-quality specimens.
