Fertility control will be used on animals released back into the wild following capture.
The muster is scheduled to begin early in September.
The bureau says the muster is needed to maintain a thriving natural ecological balance for the remaining wild horse population, wildlife and vegetation.
"The current wild horse population in the herd management area is twice what the range can handle," said Tonopah field manager Tom Seley.
If the bureau reaches its target, another muster is not expected to be needed in the area for 3-5 years.
