Point Location Description: A site within the area of the original claim S. 24,803.

Location Method: Data Compilation

Access Description: Easy access to the area is possible via the Chester Township access road that branches off the Sultan Main Haul road which connects the village of Sultan to Highway 144 near the watershed. Just south of Bagsverd Cr there is a secondary forestry road that loops around to the east and must come close to the original discoveries.

Exploration History

1934: Leslie Corbett sampled a number of widely spaced quartz veins in trenches and obtained up to 3 g/t Au (0.09opt) in channel samples from claim S. 24,803. The #4 post for this claim was supposedly located 400m east of a point where the township line intersected Schist Creek (Bagsverd Cr). Another vein was located with higher grade values in grab samples and a channel grading 1.7 g/t Au (0.05opt). This second vein was located in claim S. 24,936 which in turn was located just north of Bagsverd's lake South Arm with the #1 post on the shore of the main lake. 1984: Blue Falcon Mines carried out a regional airborne VLF-EM and magnetic survey which covered the area. 1985: Nu-Start Resources drilled three widely spaced holes on claims adjacent to the two original claims. These holes intersected a series of sericite schists described as both tuffaceous and sedimentary with minor gold values, up to 0.9 g/t (0.027opt) in small quartz carbonate veins. 1988: Seaway Base Metals Ltd held the ground and flew an airborne VLF electromagnetic and magnetic survey over the area. No ground follow-up has been reported from this survey. 2007: Augen Gold Corp. – AEM, AMag, ARAD. 2008: Augen Gold Corp. – Assays, Pr. 2010: Trelawney Augen Acquisition Corp. – Assays, GC.

Geology Comments

Dec 07, 2005 (S Fumerton) - The original discovery is located on a sheared contact between metasediments and a small porphyry lens. Crenulation folds and lineations in several directions occur in the area. Tectonic banding 3 to 10mm thick also occurs and locally represents transposed bedding.

Lithology

Lithology Comments

Dec 07, 2005 (S Fumerton) - The mineralized quartz vein is hosted in sheared arkoses which have been intruded by a quartz porphyry. The arkoses are now sericite schists with local patches of carbonate and hematite alteration.

Mineralization

Mineralization Comments

Dec 07, 2005 (S Fumerton) - Some disseminated pyrite is reported in both the quartz-carbonate veins found in the area and the sheared metasediments.

Dec 07, 2005 (A Wilson) - Grab samples at the time of discovery returned values of 3 g/t Au, channel sampling returned values of 1.7 g/t Au. Minor gold values 0.9 g/t Au were obtained during sampling completed in 1985. Grab samples collected by the OGS in 1994 returned values of 0.64 g/t Au and 0.1 g/t Ag; 0.12 g/t Au and 0.3 g/t Ag.

Geologist: S Fumerton

Notes: An attempt was made to locate the original trenching carried out in the 1930s. Since that time the ground has been disturbed by logging activities and no old trenches were found. However, a more recent backhoe trench was located southeast of the expected location and this trench was sampled. In this trench the host rock is a sericite schist with variable amounts of carbonate, based on the brown weathering probably ferroan dolomite. Subhedral, medium grained, pyrite is disseminated in the schist. A zone 2m thick subparallel to the schistosity has more intense carbonate alteration and numerous quartz carbonate veins typically up to 4cm thick which make up about 20% of the zone. The individual veins are zoned with brown carbonate on the margins and quartz in the centre. Locally quartz veining up to 10cm thick occur as boudins. No visible sulphides occur in the veins.
