The regional geological and temporal framework of the Thorn Property in the Stuhini Group of the Stikine Terrane has yielded new insights.  In particular, the Thorn high sulphidation mineralization appears related to a quartz - feldspar porphyry, the Thorn Stock.  Newly released age data for samples of mineralization yielded 91.1 Ma (Ar/Ar date on white mica) and 93.3 Ma (U/Pb on Zircon) on the stock.  Plutons along strike are 83 and 87 Ma.
