While we wait for Bernard's response, see the following quote from the November 24, 2017 HPQ press release which gets at your question:

Bernard Tourillon, Chairman and CEO of HPQ Silicon stated: "Demand for the placement exceeded the over allocation allotment potential, however we decided to closed the placement and limit dilution at this time. This round of funding provides HPQ-Silicon with the resources and flexibility to continue the advancement of the Gen2 testing and Pilot Plant Equipment project with PyroGenesis. With this round closed, the funding required for the remaining capital expenditure to complete the entire project, including running the Pilot Plant Equipment, is estimated to be $3.2 million. Regarding the financing of the $3.2 million, HPQ management is in discussion with institutions in order to complete the financing package during 2018."

Regards, Duff.

Hello Bernard

I'm curious when these questions will get answered? 

Basically, I just want to know how much money has been spent on the 200MT per year plant to date and where we are (approx in percentage) to completion of this plant?

GEN 3 as you call it.
