Feb 06, 2018 (Therese Pettigrew) - Tanton (1931) reports that on mining location T 200, one-quarter of a mile south of the southern vein of the Porcupine mine, there is a caved adit on the western side of the same hill on which the Porcupine workings are located. No vein is visible. The material on the dump is shale with veinlets of quartz, calcite, and pyrite. The adit trends north 45 degrees east. Fifty feet south of the adit, there is a trench 60 feet long in drift. Sample GCP84-363, collected by the OGS, returned assays of 0.01 opt Au and 0.18 opt Ag, with calcite and massive sphalerite. 1970 reports from Creswell Mines record assays of 25.3 opt Ag over 0.3 m, 3.2 opt Ag over 0.4 m, 27.2 opt Ag over 0.4 m, and 16.4 opt Ag over 1.5 m.
