Point Location Description: Veins on east side of Surluga Road on claim SSM 183 (DJ 11)
Location Method: Based on Assessment
Access Description: Drive south from highway 101 along the Surluga Road to the bridge over the creek, a distanc of approximately 5.5 km. The veins are located in the outcrops on the north side of the creek.
Although the veins were known to exist during the operational period of the Grace/Darwin Mine, exploration specific to the viens was not conducted until the 1980's. 1980-83: Dunraine Mines Ltd - diamond drilling, stripping, sampling, mapping. 1984: Dunraine Mines Ltd. - Dasher Resources - diamond drilling. 1988-90: Citadel Gold Mines Ltd. - stripping, sampling, mapping.

Metamorphism Type: Regional
Metamorphism Grade: Greenschist
Dec 07, 2005 (A Wilson) - The property is underlain by Jubille tuffs which are andesitic to dacitic in composition and appear to lie between intermediate to mafic and intermediate to felsic metavolcanic rocks of the 2750 Ma cycle. These rocks are only locally distributed and are absent between the intermediate to felsic and intermediate to mafic metavolcanics elsewhere in the greenstone belt. The Darwin Shear lies to the west of the veins.

Dec 07, 2005 (A Wilson) - The Nyman Vein consists of two veins within a sequence of pillowed feldsparphyric amygduloidal intermediate metavolcanic rodks. Marginal to the veins are 1 to 5 foot zones of sheared wall rocks which consist of strongly foliated wall rock with books of fine to medium-grained biotite. The veins extend eastward onto claims SSM 2401, 2401 and 2403. This area has not been very well explored.

Dec 07, 2005 (A Wilson) - Quartz in the vein is fine to medium grained and semi-granular to sugary, translucent whith to grey and has a vitreous lustre. Up to 2% fine grained pyrite and traces of arsenopyrite and rare specks of visible gold are present. Surface sampling yielded values averaging 0.554 oz/t Au across 1 foot over 110 feet of strike length and 0.58 oz/t Au across 1 foot for 50 feet of strike length. Both veins are widest at their west ends and pinch out to the east. The further projection of the trend is under an east-west segment of Trout Creek. This eastern extension is devoid of gold values.
