MLA 81-82 - Mineral Investigation Of The Madison Rare II Areas (No. 1549, Parts E, J, N, R, And S), Beaverhead And Gallatin National Forests, Madison And Gallatin Counties, Montana ? Summary

The Madison RARE II study area has four prospects with identified resources. These are listed in table 1 and are described in the following text. A high potential for Sillimanite exists at the Placer Creek occurrence (fig. 1, no. 7) and potential for phosphate rack in all areas underlain by the Phosphoria Formation. Some prospects exhibit minor potential for copper, lead, zinc, silver, and gold in the southern portion and very minor potential in the northern portion. Deposits in the northern end also have low potential for rare earth, asbestiform anthophyllite, or kyanite group minerals (including sillimanite).
