Ann: SFR: Doolgunna Project Exploration Update, page-12

SFR's SP is up again strongly today, up 3.92% to $9.27.

From the last QCash Report of AUR:

The balance of cash and cash equivalents at the end of the quarter does not include the Company's shareholding in Sandfire Resources NL (ASX: SFR) of 166,006 shares. As at 31 March 2018, the SFR share price was $7.32 equating to a total value of $1,215,163.

I assume that AUR still owns these shares. If so, then the paper gain is $323, 700. 00 as of now. Total value is now $1,538, 875.00.
