Good Morning Bernard. Great news... Thanx for the added info. Big Koodos to your team. I have a question in regards to the purity of the Quartz ? " conversion of Low purity Quartz into 4N+ Silicon Metal " Correct me if i'm wrong...... UBR changed its name to HPQ because of the "High Purity Quartz" that was discovered? What is the % difference between High Purity Quartz & Low Purity Quartz ? Thanks in advance for your time Regards . WPW
