Three-dimensional geology models were constructed to identify the mineralized domains of the mineral deposit. Mineralization is constrained geologically to the mineralized domains to accurately reflect the is situ mineralization. The mineral resource estimate was completed using Vulcan scientific software in a 3D block model, with blocks ranging from 4x4x4 meters down to 2x2x2 meters which is a size reflective of the selective mining unit envisioned for underground mining of the deposit.

The mine plan in the PFS is based on Mineral Reserves, as summarized in Table 5, which have been estimated for a combination of sub-level extraction and long-hole open stoping underground mining methods.
