Location Method: Field Visit with GPS
Access Description: Very easy access is possible as the old workings are near an exploration camp on the Chester Shannon mine access road. From the camp a new road which leads to the Chesbar site passes the workings.

Dec 07, 2005 (S Fumerton) - Within the chlorite alteration zone the foliation is not well developed. Based on diamond drilling it would appear that the quartz veining within this mineralized zone is discontinuous.

Dec 07, 2005 (S Fumerton) - The mineralization is hosted in various phases of the Chester Granitoid complex. These are mostly coarse grained, hornblende bearing quartz diorites cut by finer grained, more felsic phases. In some of the quartz diorite phases secondary, diffuse feldspar porphyroblasts are developed. Chlorite is the dominant alteration mineral and is associated with shearing. Locally the intensity of the chlorite and biotite alteration in the sheared zones imparts a schistosity to the rocks. Associated with the sheared granitoids is a cataclastic phase which consists of large (<3mm) angular blue quartz grains set in a fine grained chlorite rich matrix. The blue quartz grains are probably porphyroclasts and the rock is probably derived from granodiorite. At the east end of exposed shear there is a late stockwork of very fine grained and diffuse alteration veins which are enriched in calcite. These are in turn cut by numerous short and thin (<20cm x 2cm) carbonate veins parallel to the shear direction.

Dec 07, 2005 (S Fumerton) - The main sulphides present are pyrite and pyrrhotite with lesser amounts of chalcopyrite which occur in fine grained (<<1mm) trails or larger isolated grains (<4mm) within a diffuse zone centred upon the host shear zone. These sulphides locally form up to 3% of the rock. In addition to this semi-massive, medium grained, pyrite and chalcopyrite locally occur together quartz in short veins up to 20cm thick within the altered shear zone. The other sulphides reported occur in minor amounts.
Dec 07, 2005 (A Wilson) - Grades in underground channel samples in 1933 reportedly ran between 7 and 50 g/t over 1.5m. Resampling of the vein on surface by Murgold in 1983 returned values of 16 g/t Au across 0.85m.

Date: Jul 28, 1954
Geologist: W Savage
Notes: In his 'Makwa-Churchill' report, on page 77, Laird mentions a new showing on the Labbe property which was optioned by Porcupine Crown Mines Ltd. It was on this showing that Gomak Mines Ltd. sank an inclined shaft in 1935 and built a small mill which treated 1387 tons of ore for gold before closing down in 1936. The Gomak property was purchased in 1948 by Chesgo Mines who at that time were diamond drilling adjoining claims. The Chesgo camps, which are located on the northwest shore of a small lake about 1/4 mile east of the Gosselin camps are still in good repair. The old shaft and mill can be seen northeast of the Chesgo camps at the north end of the lake, on claim S-20009(P). The shaft is inclined at 60 deg on a bearing N28E. A trench strikes N50W from the shaft and swings to N80W. A number of old water-filled pits in the trench were put down on a small irregular quartz-sulphide veins in a blocky jointed dark coloured granite. There are flat dipping joints and two sets which strike N80W, dip 45N and N40E, dip 60NW respectively. Twenty five feet to the south of the west end of the trench, another deep trench strikes N70W. The north wall of this second trench is sheared and dips 50deg to the north. A narrow quartz vein containing stringers of chalcopyrite can be seen in the shearing at the foot of the north wall.

Geologist: S Fumerton
Notes: A brief visit was made to the area. The old mill is in a state of utter ruin with various belt drives, boilers and crusher foundations sticking out of the pile. Little is left of the shaft except scrap rails as the shaft has recently been filled in. The nearby exploration camp is in general state of disrepair and some widely spaced equipment has been burnt down. In contrast the core racks are largely intact with legible labelling.
