Point Location Description: The original discovery trench on the north shore of a small lake
Location Method: Field Visit with GPS
Access Description: The easiest access is via canoe down the Three Duck Lakes from a landing on the upper lake where the Chester Shannon Mine access road passes the lake. This road connects with Highway 144 via Lake Mesomikenda. The bulldozer trail in from the Chester logging road is not really viable but does provide easier walking for part of the distance from the lower Three Duck Lake.
1931: Working for unknown people, James Cryderman staked a number of claims covering an auriferous vein on the north shore of a small lake. Assays of 37 g/t Au and 33 g/t Ag were reported ($25.0 and 0.96opt) and the vein was traced a hundred metres to the east. 1970: Messrs John Jones and Henry Gonzales exposed the vein in a series of trenches and pits. 1979 Ken Lytle resampled the vein on surface and tested the vein with a short drill hole. Average surface sampling gave 11 g/t over a 0.5m quartz vein (0.32opt/ 1.7') and 9.0 g/t over 5.5m (0.26opt, 18.1') downhole. Assays from the drill hole included mineralized wall rock. A second hole drilled in the next year failed to duplicate these results. 1981: Hanson Mineral Exploration optioned the ground and drilled seven short holes. These were located along 30m of strike length of the vein. The best assay in a limited number was 0.9 g/t Au (0.028opt). Two additional short holes were drilled in the next year with trace quantities of gold being the best result. 1983: Mr Lytle drilled another two short holes on his own account with negative results. 1987: Consolidated Silver Butte optioned the ground and carried out a program that consisted of geological mapping, soil sampling, lithogeochemical sampling and VLF electromagnetic surveying. A number of soil geochemical anomalies were recognized and one roughly coincides with the known vein. The best assay came from the original discovery and was 41 g/t Au (1.2opt). In the following year the eastern extension of the vein was stripped together with parts of the bulldozer access road from the southwest.

Dec 07, 2005 (S Fumerton) - The dominant structure in the area is the north - south jointing which is parallel to the agmatitic zones and the diabase dykes and trend 348/90. Faulting along this trend are probable and there is a chance that the vein in the discovery trench has been offset across the diabase dyke.

Dec 07, 2005 (S Fumerton) - The host rock is a massive, coarse grained granodiorite with some quartz diorite phases which have the characteristic blue quartz of the Chester Granitoid Complex and hornblende forms up to 10% of the rock with some disseminated magnetite. This unit has been intruded by some large mafic dykes that have been in turn re-intruded by late granitic phases and pegmatitic phases derived from he granodiorite. In places these later granitic intrusions are small dykes up to 20cm thick and have a rectangular alignment but more commonly the mafic dyke fragments have been rafted into the main body of the granodiorite giving rise to an agmatitic texture. Because the mafic material was derived from mafic dykes, the agmatitic texture occurs in several zones trending north south. Parallel to the agmatitic zones are more recent diabase dykes that are up to 4m thick.

Dec 07, 2005 (S Fumerton) - Very fine grained sparsely disseminated pyrite occurs in the quartz vein in the original trench which is clear to milky white. The vein is a simply parallel sided vein with a little shearing along the margins. The other reported sulphides were not observed. To the east the vein is cut by a diabase dyke and some possible associated faulting in a section of low ground. East of the diabase a thin (<5cm) quartz vein can be traced intermittently. Unlike other mineral occurrences in the Chester Granitoid Complex there are few shears which have an easterly strike, and those that do occur are poorly developed.
Dec 07, 2005 (A Wilson) - Cryderman obtained assays of 37 g/t Au and 33 g/t Au from the vein. Lytle (1979) obtained average values of 11 g/t Au over 0.5 m and 9.0 g/t Au over 5.5 m. The best result from sampling conducted in 1987 was 41 g/t Au.
Oct 29, 2013 (P Bousquet) - Hanson Mineral Exploration Limited (1981) drilled seven holes along the vein. The intersections thicknesses vary from 0.6 to 2.9ft, with grades from 0.01 oz/t to 0.68 oz/t gold. The best intersection came from hole C-6 with 0.68 oz/t gold and 0.57 oz/t silver over 0.9ft (T-2636).
