A general contractor has been selected and all other major contracts have now been concluded. Key corporate systems, such as safety and environment, are now in place and implemented. All other corporate systems, such as the Enterprise Resource Planning (ERP) are nearing the completion of the implementation process.

On the personnel side, one of the key hires is Cregg Bossard brought aboard as the senior project manager responsible for mine construction. Mr. Bossard has more than 42 years' experience in the mining, environmental remediation, and construction industries. He has worked in operations, research and development, technical sales, engineering, and construction across the entire spectrum of the mining operations.
