| Description |
Core samples were roll crushed to a minus 10 mesh. Soil samples were roll crushed and ground in pebble mills to pass a 100 mesh sieve. The material was treated on a wet, low-intensity, magnetic separator. All 335 core samples obtained from the 11 holes were analyzed for total iron content. Representative head samples, carefully prepared from the general composite, were analyzed both chemically and spectrographically. Semiquantitative spectrographic analysis revealed the presence and approximate quantities of the metal listed in table 4. Any other elements, if present, are in amounts lower than the minimum detectable by the routine technique employed. |
