Budget estimate

$500,000 – $2,000,000

The budget for this project is likely to be in the range of $500,000 to $2 million, based on the scope of work and the number of hazardous mine openings to be closed. The project requires heavy construction and engineering services, which can be costly. Additionally, the project is located in a remote area, which may increase the cost of transportation and labor. However, the exact budget cannot be determined without more information about the project's specifics.
