Dear Steven,

The idea of building a smaller scale pilot plant was only first mentioned in our May 4, 2017, press release.

The timeline in the presentation was done beginning sept 2017, and in our September 19 Press release we describe the program as:

HPQ Silicon Resources Inc (“HPQ”) (TSX Venture: HPQ) is pleased to advise shareholders that an advanced, second stage bench testing program is about to commence. PyroGenesis Canada Inc (PyroGenesis) has informed HPQ that the Gen 2 PUREVAPtm Quartz Reduction Reactor (“QRR”) reactor, 1/250 scale model of the planned 200 tonnes per annum (tpa) Pilot Plant will be operational in the coming weeks.

Furthermore later in the same press release, we said:

Based on Gen 1 PUREVAPtm results, PyroGenesis completed the detailed engineering and design of the 200 tpa pilot plant, including substantial process modifications. Gen 2 PUREVAPtm therefore is an upgraded version of the Gen 1 Purevaptm that will be a true 1/250 scale replica of the planned larger pilot plant (Gen 3 PUREVAPtm).  The Gen 2 PUREVAPtm is undergoing final manufacturing, assembly and testing and will be operational during the first weeks of October 2017.

The question of cost and budget having been covered by other posters and by the new corporate profile on Agoracom, I have nothing else to say on that subject.

So in conclusion, I hope this cover what you were looking for.

Regards,

Bernard Tourillon
