RE:DWSTime will tell, but here's my take - The high of $0.38 you mentioned was on June 26, 2018, not June 1, 2018. The very next day, the year end audited financials were released (check Sedar) and we can all see the trend from that day on.
In the two previous fiscal years, EBITDA was north of $3m. In Q4-18, that was their worst March quarter and it was driven by lower ROW sales (if I recall correctly, a commercial agreement in China was terminated or scaled back). The Company hasn't been able to replace those revenues and profitability since. The MD&As contain segmented revenues so you can see for yourself.
I can't explain the current support, but good on you for those who've hung on to benefit from the recent uptrend. Sticking to the sidelines for the foreseable future.
