The producer confirmed that shooting on the Gore Verbinski-directed film is almost complete, in a post on his official blog.
"Almost done with filming of The Lone Ranger," Bruckheimer wrote. "125 days of shooting seemed to fly by. We dealt with winds up to 70 mph, rain, snow, and even wildfires but nothing has stopped us from filming this incredible movie.
"The cast has been absolutely amazing and we could not have asked for a better crew. Everyone has been extremely dedicated in making this film a major success.
"We have a few more filming days back in California and then post-production goes into high gear. Before we know it, it will be July 3rd, 2013 and we can't wait to share this incredible film with everyone."
Bruckheimer also posted several photographs of the film's locations in New Mexico, Utah, Colorado and Arizona.
The Social Network star Armie Hammer plays the iconic lead role of John Reid / The Lone Ranger, while Johnny Depp plays his companion Tonto.
Helena Bonham Carter, William Fichtner and Tom Wilkinson also star.
The first footage from The Lone Ranger was screened at Comic Con this year.
