Comments

Comment (Deposit): One Large Cut and Several Small Pits Were Dug Along Quartz Veins 15 Cm Or Less In Width. Quartz In Dumps Is Composed of 95 Percent Quartz and 5 Percent Combined Pyrite, Chalcopyrite and Malachite. Seven Samples of Dumped Vein Material Assayed A Trace To 5.82 Grams Gold Per Metric Tonne, 1.03 To 205.6 Grams Silver Per Tonne, and .66 Percent Copper; Although Veins Are Probably Too Narrow For Potential Resource.
