Comments on the production information

Significant Development Has Occurred At The Golden Sceptre Mine For Copper And Silver; However, No Production Has Been Recorded Exploratory Mine Work At The Golden Sceptre Mine Exceeds 1500 Meters But Followed A Prospective Gold/Quartz Vein Rather Then The Thorium Rich Quartz/Calcite Vein.

Comments on the reserve resource information

Yttrium
The Group Consists Of Golden Sceptre, Wawa, Old Outcrop, Pyrite Zone, And Tmu. Ore Mined Ug And Op From 1939 To 1949. Second Owner Is Hall Mountain Thorite (Bruce Berringer)
