1. Work is now transitioning from bench scale testing to Pilot Plant, as PyroGenesis approaches completion of phase 1 of the Process Characterization phase. Bench scale testing will continue and overlap with the start of equipment purchase and assembly of the Pilot Plant. The purpose of the Process Characterization bench scale work is threefold:
   • Determine the best and most efficient way to scale up the PUREVAP™ QRR process
   • Generate the necessary data required for the design of the 200 Tonnes Per Year High Purity to Solar Grade Silicon Metal pilot-scale system announced on August 2nd 2016;
   • Complete tests at different operational settings to identify the best and most efficient way to produce High Purity to Solar Grade Silicon Metal.
2. Payments totalling $1,072,000 were made in two tranches to Pyrogenesis in February and March to continue the work on the design and fabrication of the PureVap™ pilot plant equipment. Since August 2016, HPQ as invested $2,925,200 for the pilot equipment.
3. PyroGenesis has continued testing modifications to the process to include upgrading the Bench scale testing Plant process from batch to semi - batch processing to test for improve efficiencies.
4. The previously announced bench scale testing for 5N purity will commence shortly. HPQ has carefully prepared batches of 99.5% SiO₂ derived from its Roncevaux quartz property, selected and sorted using XRF scanning, manually crushed and has now been delivered to PYR. Once completed, a report on the purity testing, as mentioned in January (press release January 29,2017) will be finalized.
5. Project work remains on time and on budget, equipment procurement phase for the Pilot Plant has begun, all payments are up to date, and after May payment of $531,000, the next substantial payment will only be due in October to coincide with the delivery of the Pilot Plant furnace. Discussions with government agencies regarding other sources of financing are ongoing.

Bernard Tourillon, Chairman and CEO of HPQ-Silicon stated, "We continue to make positive progress with the PureVap™ process and are now setting our sights on final bench scale purity tests and the Pilot Plant. The bench scale test work has achieved most of our goals and we will report on details in each area described above as results become available. I would like to take this opportunity to thank everyone for their kind words, condolences and support during this difficult personal period."
