Point Location Description: Trenches and diamond drill holes.
Location Method: Conversion from MDI
Access Description: The occurrence is located approximately 304 m east of Winston Lake, about 32 km northwest of Schreiber (claim TB38697, claim map G-606, Pays Plat Lake). Access may be gained using the Winston Lake Mine road which departs Highway 17 approximately 8 km west of Schreiber.
Circa 1900: The occurrence was discovered and tested by 3 trenches over a strike length of 35 m by person(s) unknown. 1951: The property was staked by G. Prudehomme, who transferred all interest to S. Ciglen as part of a 40 claim (Ciglen) group. A preliminary investigation was requested by L.C. Anderson and J.W. MacKenzie and a report submitted by M.W. Bartley. 1952: Geological mapping, prospecting and trenching was undertaken on 24 claims, with prospecting and partial mapping of 16 claims. Trenching, totalling 621.8 m, over the property further exposed the main showing on TB 41534. A report of development work was submitted by A.F. Banfield, Behre Dolbear and Company. 1957: The occurrence was staked by T. Pelto, but no work was reported. 1960: The occurrence was restaked by J. Halonen. 1961: No work was recorded and the claims lapsed. 1964: The property was restaked by R.G. Roffey. 1965: All interest was transferred to Zenmac Metal Mines Limited. Two diamond drill holes, totalling 219.5 m were drilled on TB 11055. 1970: E. Starr restaked the occurrence 1971: No work was recorded and the claims lapsed. 1979: The occurrence was restaked by E.J. Nabigon, and all interest was transferred to Falconbridge Copper Ltd. Ground geophysical (Mag, VLF EM) surveys were conducted over TB 386797 (main showing) and the contiguous claim group by Superior Northwest Inc. 1984: Corporation Falconbridge Copper completed surface stripping over the showing and conducted geological mapping. 1994: Surface diamond drilling was conducted by Metall Mining Corporation, with 10 DDH totalling 316 m on the Ciglen showing. 2012: Silvore Fox Minerals carried out sampling. 2013: Golden Share Mining acquired Silvore Fox Minerals and carried out prospecting, sampling, and channel sampling. 2017: Ophiolite Consultants Pty Ltd. carried out sampling.

Dec 07, 2005 (B Nelson) - Pye (1964, p.27) described the Ciglen VMS deposit: It lies in and along the hanging wall side of a narrow band of intimately interbedded garnet biotite quartz feldspar gneiss and garnet biotite quartz schist; like these metasediments, it strikes N.10 degreesW and dips 35 degrees 45 degreesE. It is up to 17 feet thick, and has been traced along strike for 180 feet. About 30 feet east of the south end of the deposit lies a second mineralized zone. This zone has an average thickness of about 6 feet. Like the first, it strikes N.10 degreesW, dips 35 degrees 45 degreesE, and occurs in and along the hanging wall side of a narrow band of garnet schist. It is similar to the first in character, the principal sulphides being pyrite and pyrrhotite, and the suggestion has been made in an unpublished report by Banfield (1952) that it may be a segment of the first or main zone that has been cut and displaced at its south end by a fault striking N.15 degreesE. This zone has been traced in trenches for a length of 110 feet. *Banfield (1952) reported on the main showing: The mineralized zone lies in siliceous sediments which, in the vicinity of the mineralization, have been altered to chlorite mica schists, with abundant red garnets interbanded with highly siliceous bands which are up to 3 inches wide. The altered zone has an average width of about six feet, varying from 3 feet in Trench No. 3 to 19 feet in Trench No. 1. In the immediate vicinity of the trenches, schist and garnets are found only near sulphide mineralization. The mineralized zone strikes about North 10 degrees West and has an average dip of 45 degrees East.

Dec 07, 2005 (B Nelson) - The Ciglen occurrence is hosted by bimodal intermediate to felsic metavolcanic rocks. the metavolcanic rocks display hydrothermal alteration with anthophyllite, cordierite, biotite and garnet present. These altered felsic metavolcanic rocks were previously mapped as metasedimentary rocks.

Dec 07, 2005 (B Nelson) - Mineralization extends over a width of four to six feet. It consists of pyrite, pyrrhotite and sphalerite. These minerals occur in bands up to an inch wide. Some bands contain the three minerals; others are composed of only one sulphide. The sulphide bands are parallel to the schistosity and general structure of the surrounding rocks. From visual inspection, the sulphides comprise from ten to twenty percent of the mineralized zone. Chalcopyrite is present in amounts less than one percent. Pye (1964, p.27) notes that: Associated with the sulphides is considerable fine grained to medium grained smoky quartz. Much of this quartz is thought to be an original constituent of the schist; some of it probably was introduced with the sulphides. Pye (1964, p.27) reported that: The best sample ... was found to contain 5.09 percent zinc and 0.08 percent copper over a true width of 2.8 feet (Banfield 1952). The average grade of the material exposed in this trench over a true width of 16.8 feet, was calculated to be 2.17 percent zinc and 0.08 percent copper.
May 17, 2019 (Therese Pettigrew) - Sample 27552 collected in 2012 by Silvore Fox Minerals returned an assay of 50,800 ppm Zn (5.08% Zn) (Assessment report 20000007517). Grab samples collected by Golden Share Mining in 2013 assayed 14.9% Zn (with 499 ppm Cu), 9.52% Zn (with 342 ppm Cu) and 4.50% Zn (with 415 ppm Cu). The best channel sample intersection was 1.47% Zn over 5.5 m, including 4.84% Zn and 434 ppm Cu over 1 m (Assessment report 20000008045).
Dec 07, 2005 (B Nelson) - The mineralized zone lies in siliceous sediments which, in the vicinity of the mineralization, have been altered to chlorite mica schists, with abundant red garnets interbanded with highly siliceous bands which are up to 3 inches wide. The Ciglen occurrence is hosted by bimodal intermediate to felsic metavolcanic rocks. the metavolcanic rocks display hydrothermal alteration with anthophyllite, cordierite, biotite and garnet present.
