The assets pledged to back the launch of Greybull Investments' token are in the form of a precious metal-bearing concentrate material which has been prepared for processing and refining.  Industry leaders in the precious metals refining and materials analysis markets have performed rounds of test run work on dore bar samples that were smelted using the concentrate as the refining feedstock.   

Firms such as Umicore Precious Metals and EAG Laboratories have issued their certified findings on the precious metal content found in the dore bar samples.  The pledged concentrate material is barreled, inventoried and held in secure safe-keeping facilities in favor of the Greybull Investment token project.

As the concentrates secured by the Company are advanced to finish refining steps the resulting metals, known as platinum group metals ("PGMs) and rare earths, have application in the areas of AI systems development, drone and space travel, and other futuristic technologies.
