Description: The Width Of The Vein Varies From A Few Inches Up To 3 Or 4 Feet And The Ore-Bearing Streak Is Likewise As Inconstant In Its Dimensions, Changing Abruptly In Places From A Barren Vein Into Several Inches Of Ore And Again Pinching Out As Suddenly. This Is Probably Due To Post-Mineral Longitudinal Faulting, Both Horizontal And Vertical, Which Is Very Much In Evidence In The Property, With The Result That The Deposits Are Pinched In Several Places
