One thing you learn in this end of the market is patience and time frames may sometimes be stretched.

This is from the ann on the HOA -

The transaction is subject to conditions such as both parties having the right to complete due diligence within 60 days, Tychean shareholder approval and satisfaction of all legal and regulatory requirements.

Give it a week or two for them to finalise details and I am sure they will announce once any legal & compliance issues are sorted.  

Also take in context the following information from the AGM ann in regards to Juniors requirements from ASX and DD issues.

• ASX has released more stringent Listing Rules regarding ‘backdoor listings’ that preclude
  Tychean from disclosing any arrangements until after a transaction has been consummated
• Each transaction also subject to individual confidentiality agreements preventing public disclosure
• Listing Rules now place significantly higher hurdles on new transactions for junior companies such as Tychean
• Tychean to continue to conduct thorough due diligence in the best interests of existing shareholders so as to stimulate interest in the company and lead to positive outcomes

Hope this helps.

Cheers.
