HPQ Silicon Reports 1,900 % Increase In Total Mass Of Silicon Metal Produced By Gen2 PUREVAP Versus Baseline Gen1 Result

MONTREAL, QUEBEC -- (Marketwired) -- 02/15/18 -- HPQ Silicon Resources Inc ("HPQ") (TSX VENTURE: HPQ)(FRANKFURT: UGE)(OTC PINK: URAGF) is pleased to inform shareholders that PyroGenesis Canada Inc (PyroGenesis) has submitted an updated progress report on the ongoing Gen2 PUREVAP(TM ) Quartz Reduction Reactor ("QRR") test work. The Gen2 PUREVAP™ process improvements and design modifications continue to produce very encouraging results.

GEN2 AN INVALUABLE BENCH TEST PLATFORM TO COMMERCIAL SCALABILITY OF PUREVAP™ QRR

Increasing yield (Si quantity) and Production Yield of Gen2 PUREVAP™ are key objectives of the ongoing program. The results include the latest tests completed, which attained the following key milestones:

--  Total mass of Si produced during Gen2 test #007 was 28.1 grams; 20 times
   greater than the baseline Gen1 test #63 result of 1.4 grams and 1.4
    times greater than Gen2 test # 003 result of 19.9 grams(1);
--  Gen2 test #007 28.1 grams is the highest quantity of Si produced to
    date: 3.2 times greater than the best results of 8.8 grams from Gen1
    test #32(2);
--  Gen2 test #007 achieved a Production Yield(3) of 13.4%, the highest to
    date: ten times greater than baseline Gen1 test #63 Production Yield of
    1.3% and 1.8 times greater than Gen2 test # 003 Production Yield of
    7.4%;

PRODUCTION YIELD A KEY CONTRIBUTING FACTOR THE FINAL PURITY

Gen1 testing confirmed the key relationship between production yield and purity (November 1 2017 release) and from these results and ongoing tests PyroGenesis extrapolated as follows:

A.  These results support the expectation that under a semi-continuous
    PUREVAP(TM ) process, assuming standard production yield of 90%, it
    would be possible to transform Quartz (SiO2) into Silicon Metal (Si)
    with purity levels acceptable to the solar industry (4N+ or 99.998%
    Si)(4);
B.  The positive correlation between production yield, purity, and
    PUREVAP(TM ) QRR reactor size is optimized with a 50 Tonne per year
    reactor;
C.  The Gen2 PUREVAP™ reactor capacity has limited achievable production
    yield at 15% (+/- 3%).

IMPLEMENTING ADDITIONAL METHODS TO INCREASE PURITY BECOMES KEY FOCUS

With the Gen2 reactor now operating within the 90th percentile of its achievable production yield, test work in the current phase will concentrate on establishing a repeatable process at maximum yield prior to moving on to implementing and testing additional pathways to increase the final purity of the Si produced.

Purity of Gen 2 test #007 material was analyzed at (CM)(2) (Ecole Polytechnique de Montreal) using the SEM-EDS method(5) and result confirmed, as expected, the production of 99.9+% pure Si, using low purity feedstock, 98.84% SiO2.

Subsequent Si produced will be sent to outside laboratories for bulk purity analysis using ICP-OES (inductively coupled plasma optical emission spectrometry). In this area, the expertise of Apollon Solar will be a great advantage given their long track record of conducting these types of tests for material very similar to the one currently being produced by the Company.

Bernard J. Tourillon, Chairman and CEO of HPQ Silicon stated, "Our methodical approach is yielding exciting results and the Gen2 is proving to be an invaluable bench test platform for testing new design and process improvements prior to the final design and assembly of the pilot plant equipment later this year. Our objective for 2018 continue to be building on our technical successes as we get ready to commence the Pilot Plant phase with our 'Solar Silicon Team' of Pyrogenesis and Apollon Solar, as well as, building market awareness of our progress and plans. With every successful milestone, we are de-risking our project, while our ongoing tests are providing valuable information to implement the adjustments needed to produce the Solar Grade Silicon Metal necessary for the manufacture of multi and monocrystalline solar cells for high performance photovoltaic conversion."

KEY MILESTONES MOVING FORWARD

Milestones of the GEN2 PUREVAP™ program in 2018 are:

--  Tapping Silicon Metal from the Gen 2 PUREVAP™;
--  Increasing Production Yield of Gen 2 PUREVAP™ over multiple test
    cycles from high grade feedstock;
--  Testing the Purity of the Si produced and implementing additional
    methods to increase the final purity of the Si produced;
--  Testing electrical parameters of the High Purity Si;
--  Provide additional data to calculate the economics of PUREVAP™ QRR.
--  Adapt the methods and processes developed in GEN2 PUREVAP(TM ) to the
    final design and assembly of the Pilot Plant equipment.
