Location Method: Field Visit with GPS
Access Description: From Highway 144 access to the occurrence is easy. Initially by taking the Mesomikenda Lake Road to the lake of the same name then the mine access roads to the Young Shannon and Gomak Mine sites. Leading off the mine access road are a series of good drill roads which end at the occurrence.

Dec 07, 2005 (S Fumerton) - A series of narrow, closely spaced, steeply dipping, anastomosing, shear zones occur as discontinuous structures in a broad zone. Locally in some of the shear zones a cataclastic microbreccia has been developed with the blue opalescent quartz grains forming common 'elliptical' porphyroclasts and less common angular clasts. In such cases the matrix to this microbreccia is strongly foliated and rich in calcite and chlorite. Individual shears are mineralized with sulphides and commonly measure 0.1 - 2m in width and greater than 20m in length and the broad zone which contains the individual shears is roughly 30m wide. The broad shear zones themselves are repetitive and some of the smaller ones are spaced about 50m apart. Adjacent to the shear zones where the host rock is altered, a strong foliation is developed.

Dec 07, 2005 (S Fumerton) - The mineralization is hosted in the more mafic phases of the Chester Granitoid complex with coarse grained diorite phases with up to 50% mafic minerals. The mafic minerals are hornblende, pyrite and ilmenite. Chlorite plus epidote occur as an alteration product. This mafic phase is cut by a number of irregular, medium grained, leucocratic granodiorite dykes that are up to 5m thick. Some of these granodiorite dykes contain small, altered, metavolcanic xenoliths. The deposit is bisected by a number of northwest trending diabase dykes and smaller dykes which are parallel to the mineralized shears. In addition to these diabase dykes there are a number of small irregular dykes rich in brown carbonate and chlorite. Widespread pervasive brown carbonate alteration occurs in the general vicinity of the shear zones. Closer to the shear zones chlorite and biotite occurs in coarse disseminated grains and in finer, subparallel grains which tend to be concentrated in bands and impart a gneissic appearance to the rock. There is also a broader distribution of fine disseminated pyrite grains. Locally within the alteration zone there is a patchy development where anhedral grains of feldspar occur in <1cm aggregates with a hornfelsic appearance. Adjacent to the larger shear zones the host diorite has been altered to a fine - medium grained felsic unit. This unit also has a higher sulphide content than the adjacent diorite.

Dec 07, 2005 (S Fumerton) - The discontinuous shear zones are the locus of the mineralization. Some of these shears have an axial quartz, or quartz / carbonate or massive to semi-massive sulphide veins. The sulphide veins are up to 5cm thick and the less common quartz veins tend to occur in pods up to 30cm thick. Pyrite, chalcopyrite, pyrrhotite and pyrolusite form between 1-30% of these veins. In the wall rock sulphides occur within the alteration zone as disseminated medium to coarse grains, fine scattered veinlets or in thin stringers. The chalcopyrite tends to be coarser than the other sulphides and concentrated in the veins and sulphide stringers. Some sulphides also occur in the open voids associated with the development of north trending joints and some local brecciation. This suggests two stages to the mineralization but the second may be remobilisation of the earlier phase.
Dec 07, 2005 (A Wilson) - Chip samples collected by the OGS in 1980 returned values of 3.77 g/t Au and 6.2 g/t Au.
Dec 07, 2005 (A Wilson) - Chlorite, biotite and carbonate are also present as alteration minerals.
