Ann: Hillgrove Antimony-Gold Project Delivers Compelling DFS, page-126

No, you aren't right.
You have taken a 'life of mine" FCF (1.7B) and applied a P/E ratio to that.

You need to take "annual" FCF and apply the P/E ratio to that.
This will bring you to a valuation in the $2B range, rather than your $17-24B range.

As a rule of thumb, 100k oz producers are currently valued around $1.4-$1.5B

LRV, although using a conservative 85,000 oz Equivalent, will, at spot, be cash-flowing 350M which is similar to a 115-120k oz gold producer in FCF.

So, a rough valuation would be 1.45 B x 1.2 (120k oz equivalent) = $1.74 B

Again, within the range mentioned above.

When you come up with valuations that are 8-10x what established peers are valued at, it's probably an error in calculation.
