Dear silverbed79,

Thank you for your questions, please find below my answers.

UPDATE ON PUREVAP DEVELOPMENT

As stated in our May 4 PR, the lab scale Purevap equipment is being modified to allow its operation in a semi-batch process mode.  Will these modification are being made, purity testing are still ongoing using the old set-up of the PUREVAP™ lab scale equipment.

UPDATE ON ONGOING SILICON METAL PURITY TESTING

In our June 23, 2017, Press release we talked about our new testing protocol:

“The new testing protocol will first assess the homogeneity of the silicon phase by Scanning Electron Microscope - Energy Dispersive Spectroscopy (SEM-EDS) in back scattering mode before any destructives test are completed.  While the addition of this step increases the time before we get any results above 3N+ purity, this step was deemed critical in assessing sample purity level.”

“Once these results have been analyzed, the material will be sent to a third-party laboratory for either Glow Discharge Mass Spectrometry (GDMS) testing or Inductively-Coupled-Plasma Mass-Spectrometry (ICP - MS) testing and in some case even both.”

We then finished the PR with:

Testing for the purity of some of the material produced using lower quality feedstock (test #54 to #74) and some material produced using high Purity Quartz (99.5% SiO2) (Test #75 and above), but still using the old set-up of the PUREVAP™ QRR, have begun this week.

At this time, all that I can add is that we have completed the (SEM-EDS) in back scattering mode testing and material is being prepare to be sent to a third-party laboratory in the USA. 

As a matter of policy we do not give anymore any timeline on test results completion, but are committed to make timely disclosure of material events.

UPDATE ON PILOT PLANT

We are very satisfied with the progress being made and have nothing new to add other then things are advancing as planned.

GOLD SPIN OUT UPDATE

Patrick issued an update on Agoracom a few days ago, nothing as change since then.
