Point Location Description: Shaft 1 AMIS location

Location Method: Data Compilation

Access Description: These occurrences are located on the north shore of Little Duck Lake about 2.5 km west of Duck Lake. The area is approximately 25 km north of Schreiber (claim map G-609). Corporation Falconbridge Copper make reference to Little Duck Lake #1, #2 and #3. Little Duck #1 is located just west of line 25W at 8+00S. Little Duck #2 is located on line 31W and line 30W at 7+50S. Little Duck #3 is numerous pits in the vicinity of line 27W, 7+75S. Easiest access is by aircraft from Thunder Bay or Pays Plat to Little Duck Lake. The deposits are on the north side of the lake. A diamond drill trail leads from the Winston Lake mine to Big Duck Lake.

Exploration History

1915: Known as TB 746. 1918: The claim was held by the Duck Lake Mining Company who performed surface work and underground development. 1927: Harrison Syndicate held the property. 1930: Haslat-Duck Lake Mines performed surface work and underground dev't including 3 shafts. One shaft is reportedly 18 m deep with 21 m of crosscutting. A second is reportedly 36.5 m deep. On Dec. 15, 1929, operations were closed down. 1951: The property lay idle for many years. It was acquired by S.J. Zacks in 1951, and 2 of the deposits were drilled by Magnet Consolidated Mines Ltd. Ten holes, totalling 896 m, were drilled. 1954: Property was further investigated by Bathurst Mining Corp. Ltd. and Maritimes Mining Corp. Ltd. An EM survey was carried out. Anomalies were further investigated by mag surveys and trenching. Twenty-five trenches, totalling 518 m were dug to test the geophysical work--these failed to locate anything of value. 1959: The Little Duck Lake deposits were acquired by V.B. Feeley and J.P. McDermott of KRNO Mines Ltd. 1980: T.W. Noble staked the showings and transferred all interests to Noranda. 1981: Ground mag and unspecified geophysical surveys were completed. 1982: Geological, geochemical and geophysical (mag, EM and IP) surveys were completed. 1983: Airborne Mag-EM survey conducted. 1984-87: Noranda transferred all interest to Falconbridge, who carried out a geochem survey, geological mapping, and power stripping. A substantial drill program was conducted. 1990: An IP survey was conducted. 1993: Rusty Lake Resources and Metall Mining Corp. conducted diamond drilling mainly on the Coco-Estell and Nelson Pit occurrences. 1995: The Big Duck Lake property is held by Inmet Mining Corp. 2013: Clear Gold Resources Inc. carried out prospecting and sampling.

Geology Comments

Dec 07, 2005 (B Nelson) - The average width of the No. 1 deposit is about 20 feet. It is not a simple vein, but rather a composite structure, made up of bands of chloritized hornblende schist or metadiabase alternating with veinlet, stringers and lenses of fine-grained, sugary textured carbonate. The sulphide content varies greatly; in some places, the sulphides are present in small amounts as disseminations; in other places they form small lens-shaped or irregular-shaped masses. The No. 2 deposit is a vein found about 1700 feet west of the No. 1 deposit. About 10 feet of its total width is exposed at the lakeshore, in a pit and trench, for a distance of about 75 feet. It strikes N15 degrees E and, as far as can be ascertained, dips steeply west. It is a sugary-textured carbonate vein, in hornblende schist, and is well mineralized. The No. 3 deposit is exposed in a deep open cut about 25 feet long and 10 feet wide, approximately 700 feet east of the No. 2 deposit. It is in hornblende schist, and is a lens-like body not larger than 15 feet long and 8 feet wide, of quartz and abundant metallic sulphides. The lens strikes N60 degrees E, and dips about 75 degrees NW.

Mineralization Comments

Dec 07, 2005 (B Nelson) - Wells (1984) described the Little Duck #1 as a carbonate-quartz vein with pods of massive sulphides (sp, py, gn, cp) crosscutting stratigraphy. An intensely biotitic and chloritic QP dyke is intimately associated with the mineralization. The carbonate vein is thought to be related to a north-south structure but it is uncertain as to when the actual vein was emplaced or where the source of the metals is located. The Little Duck #2 consists of massive sulphides (sp, po, py) exposed in a trench, with exposure too poor to establish the nature of the style of mineralization. Little Duck #3 is similar to #1. The carbonate veins are polymetallic (sp, gn, py, cp). There are lenses of massive sulphides exposed in one of the pits. A 100 lb bulk sample tested at Ottawa returned values of 4.94% lead, 8.05% zinc, 0.19% copper, 0.11 oz/ton Au and 2.06 oz/ton Ag. Tin was nil. Wells (1984) took a grab sample from Little Duck #3 which assayed 9.82% Zn, 7.65% Pb, 238 g/t Ag and 41.5 g/t Au. Two grab samples (TBS 1560 and 537) assayed 0.11% Cu, 9.49% Zn, 7.1 g/t Ag, 0.16 g/t Au; and 0.06% Cu, 25.5% Zn, 0.01% Pb, 9.1 g/t Ag and 451 ppb Au respectively.

May 17, 2019 (Therese Pettigrew) - Samples collected by Clear Gold in 2013 returned the following assays: Sample 237003: 24 ppb Au, 201 ppm Cu, 27 ppm Pb, 9952 ppm Zn; Sample 237005: 298 ppb Au, 6 ppm Ag, 3451 ppm Cu, 316 ppm Pb, 96021 ppm Zn (9.60% Zn); Sample 237006: 506 ppb Au, 25 ppm Ag, 2674 ppm Cu, 412 ppm Pb, 47172 ppm Zn (4.72% Zn); Sample 237007: 868 ppb Au, 31 ppm Ag, 3811 ppm Cu, 379 ppm Pb, 61321 ppm Zn (6.13% Zn); Sample 237020: 527 ppb Au, 41 ppm Ag, 529 ppm Cu, 60168 ppm Pb (6.02% Pb), 58403 ppm Zn (5.84% Zn); Sample 237027: 57 ppb Au, 5 ppm Ag, 693 ppm Cu, 575 ppm Pb, 45661 ppm Zn (4.57% Zn); Sample 237029: 85 ppb Au, 18 ppm Ag, 1769 ppm cu, 4658 ppm Pb, 77430 ppm Zn (7.74% Zn); Sample 237031: 887 ppb Au, 23 ppm Ag, 609 ppm cu, 37984 ppm Pb (3.80% Pb), 61529 ppm Zn (6.15% Zn) (Assessment file 20000008066).

Alteration Comments

Dec 07, 2005 (B Nelson) - The schist enclosing the lens (No. 3 deposit) has been altered, and exhibits some biotite and chlorite.
