Ore controlOre Is Localized At The Intersection Of N25w And N35e Fault Sets. These Faults Have Been Intruded In Places By Igneous Dikes. Thin Bedded Siliceous Sedimentary Rocks Immediately Above Massive Limestone Are A Less Important Stratigraphic Control.
Geology
Host rockMudstone
Associated rockDiorite
StructureRoberts Mountains Thrust Fault., Multiple Fault Sets Are Recognized. North-Striking High Angle Normal Faults Are Offset By Nw- And Ne-Striking High Angle Normal Faults. E-W-Striking High Angle Faults Offset All Other Structures.
AlterationSilicification And Argillization. Silicification Of Both Carbonate And Siliciclastic Sedimentary Rocks Predates Gold Mineralization. Late Stage Argillization Overprints Silicification Near Dikes And Structures And Is Associated With Gold Deposition.
