It's interesting doing this sort of analysis. I took a look at the share prices of 3 miners - Sandfire, Chalice and De Grey to see how much of the price gains were in the first 12 to 18 months from discovery / when they began their runs.
De Grey - 5c Jan 2020 to $1.50 in Sept 2020 - Just 9 months and now trading around $1.18
Chalice - 16c March 2020 to $9 in June 21 - Just 16 months and now trading around $8
Sandfire - 15c May 2009 to $7 in Dec 2010 - Just 20 months and now trading around $6.70
A small sample pool I know but if we in fact do have a major discovery on our hands then looks like it pays to hold onto your shares for at least about 18 months while it plays out.
