Budget estimate

$500,000 – $2,000,000

The budget for this project is difficult to estimate without more information on the scope of work and the requirements of the remediation. However, based on the fact that the project involves remediation of 9 abandoned mine features, the budget could be in the range of $500,000 to $2 million, depending on the complexity of the work and the materials required. Factors that may influence the likely payment range include the cost of labor, equipment, and materials, as well as any potential environmental or safety hazards that may need to be addressed.
