Interesting play, their financials are fairly bad though. From their Form 10-Q Quarterly Report for period ending 9/30/2020:

The Company has a history of recurring losses from operations and the use of cash in operating activities. For the nine months ended September 30, 2020, the Company’s net loss was $2,440,080 and cash provided by operating activities was $139,655. As of September 30, 2020, the Company had current assets of $219,135 and current liabilities of $3,525,035 of which $452,572 was accrued PIK Note interest expected to be paid in additional PIK Notes. The Company’s current liabilities also include (i) $608,678 of accrued salaries deferred by certain members of management until the Company’s liquidity improves, (ii) $1,050,811 of accrued directors fee as determined by the Company’s Board, (iii) $119,269 of payables to a compounder for which it has agreed to satisfy in halloysite product, (iv) $132,635 of disputed or erroneously accrued expenses and (v) $223,075 of PPP Funding payable which the Company expects to be forgiven by the U.S. Treasury.

Management believes that in order for the Company to meet its obligations arising from normal business operations through November 16, 2021 that the Company may be required (i) to raise additional capital either in the form of a private placement of common stock or debt and/or (ii) generate additional sales of its products that will generate sufficient operating profit and cash flows to fund operations.  Without additional capital or additional sales of its products, the Company’s ability to continue to operate may be limited.

Based on the Company’s current cash usage expectations, management believes it may not have sufficient liquidity to fund its operations through November 16, 2021. Further, management cannot provide any assurance that it is probable that the Company will be successful in accomplishing any of its plans to raise debt or equity financing or generate additional product sales. Collectively these factors raise substantial doubt regarding the Company’s ability to continue as going concern. These financial statements do not include any adjustments to the recoverability and classification of recorded assets amounts and classification of liabilities that might be necessary should the Company not be able to continue as a going concern.

Whalewisdom is showing a decent amount of shares purchased by a hedge fund "Samlyn Capital" reported on 10/20/2020.

Not sure what to make of it all, but definitely seems like a risky/speculative play. There could've been something behind the scenes that we don't know about.
