Point Location Description: AMIS adit location
Location Method: Conversion from MDI
Access Description: Proceed west on Highway 11-17 to Highway 588. Turn left (south) onto Highway 588 and proceed SW for 12.5 km. At this point there is a gravel road on the left. Turn onto the gravel road and proceed westward to the old Porcupine mine site. From the Porcupine mine site clearing, proceed at a bearing of 031 degrees azimuth through dense bush for 345 m. The Silver Creek Mine adit is located in this vicinity, in the east face of a mesa.
1883: vein was discovered by O. Dounais. 1885-87: 22.9 m tunnel and a small test pit deep in the tunnel. A 6.1 m winze was developed. Development ceased in 1887. 1919: an unspecified amount of development work was reportedly performed by Canadian Mineral Resources Company Ltd. 1931: a few feet of rock had been removed to a height of 6.1 m above the portal of the tunnel. 1933: Animikie Mines reported the tunnel was 47.5 m deep. Near the entrance to the tunnel was a 13.7 m shaft. Trenching was conducted. 1965-70: Creswell Mines Ltd. conducted geological mapping, and the mine was dewatered and sampled. 1993: J.W. Redden conducted stripping.

Feb 06, 2018 (Therese Pettigrew) - Flat-lying Rove shales are capped by a Keweenawan diabase sill. A brecciated zone occurs along a fault found on the property. The main fault trends 065 degrees and dips 80 degrees to the SE. A fissured and brecciated zone up to 1.2 m wide occurs along the fault. The zone is cemented by vein material consisting of calcite, quartz, amethyst, and green fluorite. Sparse mineralization of galena, sphalerite and pyrite is present. Local concentrations of argentite and native silver were also found in the vein material (Tanton, 1931). A 5 oz sample assayed by the Geological Survey of Canada in 1887 gave 2.567 opt Ag. A.C.A. Howe International Ltd. conducted a sampling program across the entire length of the Silver Creek adit. Assay results from the samples indicated a grade of 2.2 opt Ag across an average width of 0.5 m for a length of 56.1 m.
