| alteration: | Wall Rocks Are Chloritized, Kaolinized, And Sericitized. At Least Two Stages Of Mineralization And Alteration Have Been Recognized. During The Earlier Stage Wall Rocks Were Silicified, Whereas Later The Wall Rocks And Wall Rock Inclusions In Quartz Were Pyritized And Gold Was Introduced With Fine-Grained Pyrite. Pyritization Usually Extends Only 50 Cm Or So From The Vein, Whereas Chloritization May Be Recognizable As Much As 150 Cm From The Walls. |
| conc_proc: | The Veins Are Oxidized To Depths Of 40-60 M Below The Surface, But No Secondary Enrichment Has Been Recognized |
