Is Regis Resources (ASX:RRL) Undervalued On The Duketon South Mine Shutdown?

Regis Resources (ASX:RRL) is in focus after a contract worker died at its Duketon South gold mine, leaving the Rosemont process plant shut and raising fresh questions about operational risk and valuation.

Yet Regis Resources still shows a 1 year total shareholder return of 7.37% and a very large 3 year total shareholder return, suggesting long term momentum has been far stronger than the shorter term pullback.
