The engineering work completed to date has been much more detailed than is normal for a project at the preliminary economic assessment (PEA) stage. We believe that Zenyatta is a leader in developing a new cost-effective process for the production of ultra-high purity natural graphite. Further purification test work is underway to produce a potential range of purities that are required by end-users. This is based on discussions with interested end users related to strict specifications under signed confidentiality agreements.

above from last NR interpretation is as we have concluded, both the "demand for further purification" and "more detailed work than a normal PEA" (more like a Pre feasability PFS) looks clearly driven by the NDA companies which is great because once delivered these companies will be satisfied to make offtakes or outright acquisition. we are on the right track. PEA will not necessarily be required for one of these entities to make a move IMO
