NO it is not too late.

If your holding becomes marketable ( worth $500 or more) by the end of the Notice Period then your shares will not be touched. The end of Notice Period is 29 January 2019. So people can buy on market until then.

Extract from the letter :

"If the market value of your Flinders shares increases during the Notice Period, due to an increase in the Flinders' share price, so that your shares that were previously identified by Flinders as being an unmarketable parcel become a marketable parcel (i.e. their value becomes equal to or greater than A$500), the Company will not sell your shares.

Alternatively, if you increase your holding of Flinders shares during the Notice Period to a marketable parcel, Flinders will not sell your shares. If you sell your Flinders shares prior to the end of the Notice Period, no further action will be taken "
