Q: This company advertises that both Eric Sprott and First Majestic are investors. Are the size of these investments significant enough to indicate a fairly strong conviction?

On the Insiders report on your site I see the following during Sept 2020:
Shares Traded: 4,621,241
Transaction: Buy under a prospectus exemption at $1.40 per Share
Value: $6,469,737.00
Shares Held: 0

There are three separate transactions listed with the same figures, except that one shows Shares Held as > 0.

What should this tell me? Why is "Shares Held" = 0 after two of the transactions?

Thanks,
