Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comment (Location): Antelope Project includes 4 main claim blocks: AB (Antelope), RF (Twin Buttes), SM (Sheep Mountain), WY (formerly JAB) claims as well as other mineral claims. Emphasis is on the WY 1-40 (JAB) claims in the Tech Report. Wy 41-81 (Cyclone) claims are also part of the Project. Lat/longs are given for each of the 5 blocks. Perhaps each should be a separate MRDS record?
