Also keep in mind that an individual/party recently took part in the non-brokered private placement as the sole placee. This placee funded HPQ Silicon for $3,604,000 (for 6,800,000 shares).
Keep in mind the impact that Covid had on everybody/everything, the whole world got a little sidetracked/disrupted.
Patience is required. This is highly technical work that HPQ/PYR are doing and I'm fully confident that us shareholders will see not only success but massive industries' disruption and adoption. Patience will be rewarded!
