Ann: Black Rock signs POSCO Strategic Alliance & Development MOU, page-143

positive news from EGR today, which may indicate why BKT's nearby graphite is wanted by POSCO:

Results confirmed the preferred EcoGraf™ feedstocks, including the Company’s Epanko material, consistently outperformed existing material under various electrochemical test conditions. The testwork also confirmed that the physical properties, mineralogy and degree of crystallinity of each natural graphite source directly affects battery anode performance within the lithium-ion battery. This is a significant observation as each graphite source has its own unique geological setting, with some sources unable to meet the strict specifications of the battery manufacturers. Crystallinity is an important property in the lithium-ion battery as the level of crystallinity affects the electrochemical performance. In natural graphite deposits, crystallinity is determined by the geological setting and the extent of natural temperature, pressure forces and time that has been applied in the formation of the graphitic rocks. Higher crystallinity results from higher temperature and rock pressures for a longer period of time
